"Rosie, we need to talk." Tonya said as she barged into the room.  The pair had been best friends ever since playing the twin leads in an elementary school play.    Fast forward a dozen years and they were roommates together in college.

            Rosie was studying at her desk and looked up as her roommate approached.  The pair were total opposites.  Rosie was quiet and studious, with thick brown hair and glasses that gave her a librarian air.  Tonya was blonde and outgoing, the head cheerleader turned college party girl.  Where these differences would have driven another pair apart, the young women counterbalanced each other's personalities.  Tonya got Rosie out of the house, while Rosie reined in some of the blonde's crazier ideas.

            "Tonya, can this wait?  I have a midterm to study for tomorrow."

            The agitated blonde shook her head.  "No, it can't wait.  We need to talk about Trevor."

            Rosie gulped.  Trevor was another old friend, in fact the girls has met him during the same play they met each other.  Growing up the three had been inseparable.  Then…puberty got in the way.  Both women had suddenly wanted more, while Trevor remained oblivious to their interest.  The unspoken conflict had seen Tonya run through boyfriends like bathroom tissue, while Rosie had relegated herself to writing erotic literature.

            And so the status quo had remained, until last week.  Rosie had accidentally left a story she was editing out on the bed while Trevor was over, he'd seen it, and the big metaphorical shoe had finally dropped.

            "I didn't mean for him to see that."  Rosie began meekly, before finding an inner resolve of courage.  "But I'm not sorry he saw it.  I do love Trevor, even if he can be oblivious at times."

            "I know how you feel, I love him too."  Tonya said.  "All these years I've tried to find that spark with someone else, but couldn't.  Maybe if you tried, we could find someone else for you."

            "Or maybe if you tried a bit harder on your dates instead of phoning it in."

            The two started at each other in annoyance for a long minute before Tonya let out a long sigh.  "If only there were two of him, so we'd each have one to date."

            Anger deflating, Rosie replied, "Even then I don't know if it would work.  Some days I think the only thing Trevor can love is his pet snake.  With how clumsy he is, I'm amazed he's managed to keep her alive all these years."

            The pair were silent for another minute before Rosie said wistfully, "Maybe we're going at this backward.  Maybe instead of two of him, we only need one of us."

            Tonya shook her head.  "That leads us right back to the argument of which one of us get him…." the blonde trailed off, considering.  "There is a way.  What if we were one person?  That way we'd both get him."

            Rosie's eyes went wide.  "You're talking a merging?  Alchemy?"

            Tonya nodded.  "It wouldn't be cheap, but hey, we'd save a fortune on living expenses.  That is, if you'd be willing to spend the rest of your life with me?"

            Rosie didn't need any time to consider.  "I haven't grown to hate you over the last decade.  I think a few more will be tolerable…"  It was the brunette's turn to trail off in though.

            "I can see something devious brewing behind your eyes Rosie.  What is it?"

            Rosie's face slowly split into a smile.  "I think we need to add one more to our merging plans…."

______________________________________________________________________

Three weeks later

            "Roise!  Tonya!  Are you home?" Trevor called as he stepped through the front door of the women's apartment.  Trevor knew he best friends had been fighting over something recently, even if they hadn't let him in on the details.  However, the note they'd sent him earlier made it sound like the hatchet was buried.

            "In here!" a pair of voices called back, coming from Tonya's bedroom.  They sounded a bit off, but Trevor chalked that up to the closed door.

            Taking his friends' words as an invitation, Trevor knocked on the bedroom door and stepped inside.  The room beyond was pitch black; even the blinds had been covered over with something to prevent even the faintest ray of light from seeping in.

            Trevor took another step forward and nearly tripped over something on the floor.  It felt like a good size fallen log.  "What are you two doing in the dark?"

            "Waiting for you." Rosie replied, her voice coming from over where the bed should be.  There was the snick of a slight switch.  Blinded, Trevor blinked furiously to try and clear his eyes.

            There was movement behind Trevor and something pressed into his back.  "A big surprise deserves a little theater.  And we have a very big surprise for you." Tonya hissed in his ear.

            Trevor's jaw dropped as the figure on the bed came into focus.  It was Rosie, naked as the day she was born.  This was scandalous, but not really surprising.  Trevor had seen his friends nearly naked several times over the years.  What shocked Trevor was that Rosie looked a lot different than when he'd seen her a few days ago.

            It was if Trevor's friend had absorbed the essence of a snake.  Rosie's thick brown hair was no more, replaced with a wide cobra's hood that ran from her widow's peak to the back of her neck.  Her nose seem a little flatted and eyes a bit bigger, but otherwise Rosie's face was much the same.

            As his eyes traced downward Trevor saw Rosie's body had changed as well.  Her breasts appeared twice as big as before, lush orbs the size of grapefruit.  There were also three times as many, with the triplicate bosoms stacked atop each other down Rosie's chest.  Rosie was in the midst of playing with them, cupping the upper pair while pinching the nipples on the lowest pair.  How…then Trevor realized his friend now had four arms as well.

            Rosie's lower body hung off the side of the bed, which prevented any hints about the state of her legs.  But as Trevor's eyes fully cleared the biggest change finally came into focus.  Instead of skin, Rosie was completely covered in scales.  They were mostly brown and tan, covering Rosie's body like tribal tattoos.  Here and there were hints of red and black, accenting the curve of a breast or the line of Rosie's hood.

            "Rosie, what…" Trevor began, before Tonya leaned in to whisper in his ear again.  The young man could feel the woman's forked tongue caressing the rim of his ear as she spoke.

            "Do you like our changes?"

            Trevor spun around, took a step back, and tripped on something on the floor.  As he fell on his butt, Trevor looked up to see Tonya had changed as well.  Her changes matched Rosie, with multiple limbs, scales, and a cobra's hood instead of hair.  Even the scale pattern was the same, leaving the two women nearly indistinguishable.

            "Why…how…" Trevor stammered.

            This low to the ground, he could see the swell of Tonya's hips transition into the tubular body of a snake.  That had been what Trevor had tripped on, the fleshy cylinder looping off back toward the bed.  Trevor craned his neck to follow it, until the tail curled behind the corner of the bed Rosie was sitting on.  As if she was following his gaze, the snake woman lifted herself off the bed and came around to give Trevor a closer look at his changes.

            It was then that Trevor realized the two women in the room were linked.  What he'd first through was Tonya's tail eventually thickened into Rosie's upper torso.  They were a double ended snake, flanking him on either side.

            "I think we'll start with the second question." Rosie said, her forked tongue tasting the air.  "It's rather simple really.  You can do so much with alchemy these days, especially when you have connections with a reliable shop."

            "As for why," Tonya continued, "Rosie and I had an epiphany while arguing over which one of us would get you."

            "Get me?  I don't…"

            Rosie rolled her eyes.  "He really is an idiot, isn't he."

            "Almost makes me wonder why we love him so much."  Tonya smiled, revealing canines that, while not on the level of fangs, were certainly longer than the standard human issue.  "Trevor, we both love you.  Have loved you, for a very long time.  Only you were too blind to see it and make a choice between us.  So we've taken that choice away.  If you won't love one of us, we decided to become one, so you could love both of us."

            The reality of the situation finally hit Trevor and he sat there stunned for a long minute.  He finally said, "I guess I owe you two an apology for being so blind."

            "Don't worry, we'll find ways for you to make it up to us."  Tonya replied, bending down to grab Trevor under the left arm.  On his other side, Rosie had an identical grip on his right.  The women pulled back upright, easily lifting Trevor off the floor.  Together, they slithered over to the bed and dumped Trevor down atop
it.

            "You want the top or bottom Tonya?" Rosie asked.

            The snake woman licked her lips.  "I think top.  I want to get some kisses in while we undress him."

            "Works for me." Rosie replied as she started undoing Trevor's belt.

            Trevor was about to protest, when Tonya leaned in and grabbed his attention with a kiss.  The snake woman's tongue was long enough to nearly go down his throat.  Before Trevor knew it he was buck naked and sandwiched between his lovers.  Rosie took over kissing duties, while Tonya played with his dick until Trevor was as hard as an iron bar.

            "I think we've gotten him sufficiently hot and bothered." Tonya said, admiring her handiwork.

            "I think it's time for the big event."  Rosie pulled away from Trevor's face, while using her arms to point his head at her chest.  She ran a finger down the gap in her cleavage, parting the scales like a zipper to reveal the pulsing pink flesh beneath.

            "Is that a…vagina?" Trevor asked.

            "Don't be coy Trevor." Tonya laughed and nibbled his ear.  "We've found your porn collection, so we know you know what a vagina looks like.  But to answer your question, yes, we have our vaginas between out breasts.  Two in fact.  A necessity with the changes to our lower bodies."

            Trevor felt himself lifted into the air by Tonya as Rosie lay back on the bed.  Tonya set him down on her bodymate's chest, Trevor's dick sinking into her fleshy folds.  The unexpected, near instantaneous shock of purse pleasure caused Rosie to let out a moan.

            "It feels so good.  Please Trevor, put yourself deeper inside me."  Not quite sure what to do, Trevor mimicked the women he'd seen riding cowgirl in porn videos and started bouncing up and down on Rosie's chest.

            "Oh yes, that feels amazing.  Are you feeling this too Tonya?"

            "Of course I am.  We are sharing a body after all."  Tonya wrapped herself around Trevor's torso, crushing her many breasts into his body and her lips into his face.  Trevor began to think of himself as the sex toy in his friends’ masturbatory play as Tonya took over the movement of his body.  She plunged him in and out of Rosie's chest, faster and faster into Trevor couldn't take it anymore.

            "I'm gonna…gonna…cum…"

            The women were right behind him and Trevor was nearly smothered as Tonya crushed him even tighter while the orgasm spasmed back and forth through the body she shared with Rosie.  Only when his air reached critical levels did Tonya's coils loosen, allowing Trevor to slump back on the bed next to Rosie.  Tonya snuggled in on his other side, creating a Trevor sandwich.

            The trio lay there for a long time, soaking in what had just happened.  It was Trevor who finally broken the silence.  "So…how is this going to work exactly?" he broached.

            "Officially, Tonya and I are one person.  It was actually fairly easy to do the paperwork.  Apparently merging are a more common college experience than I realized." Rosie explained.  "On a more personal level...we share all sensations, so I don't need to be jealous of attention you lavish on Rosie and vice versa."

            "We share a mental connection as well." Tonya added.  "It should help a lot with studying as we finish off our last classes.  However… the alchemist warned us that over time our personalities might merge into one.  But for now you can still think of us as Tonya and Rosie."

            "This is quite a lot to take it." Trevor admitted.  "I wonder what Ms. Slithers would think about our situation if she was here?"

            "Actually, she is here." Rosie admitted sheepishly.

            "We joked that the only thing you loved was your pet snake, so when we merged together we used her for the source of the snake DNA." Tonya added.  "I think one reason we're able to move so well is she guides our serpentine movements."

            "Seriously?"  The women nodded.  "In that case, I think that makes you two my pet as well."

            Rosie rolled her eyes as Trevor's attempt at playful banter.  "In that case, what is your desire, Master?"

            "I think I know." Tonya said, curling around to stare at Trevor's growing erection.  As she ran a finger down her cleavage, revealing the vaginas hidden there, Tonya added, "I think it's time for round two."

Damn, that's good.

Thanks for the support guys.  I deliberately kept these stories lighter as I eventually plan to post them on other sites.  While this next one technically takes place in Belial, I used it only for the transformation culture.  I hope you still enjoy it.  There should be 1-2 more I'll finish this weekend.

_________________________________________________________

            Lorraine struck a pose before the mirror and smiled.  The white gown around her body was so sheer it was nearly translucent, revealing almost as much as it concealed.  As wedding dresses went it was on the scandalous end of the scale, but it was her special day after all.  The bride should get to pick the last set of clothes she would ever wear.

            Lorraine reached up and touched the small vial hanging from a silver chain around her neck.  Apart from her dress, it was the only other thing she was wearing.  Set into top, where the stopper would be, was a small diamond.  Not a traditional engagement ring to be sure, but Rhett wasn't an ordinary fiancé.

            Had it only been a year?  It felt like longer.  Lorraine had met Rhett in a coffee shop of all places, she on her way to work and him on his way to class.  Lorraine had never met anyone from the Realm before and was surprised when Rhett told her he was in the Empire for a farming cultural exchange program.  Lorraine had expected everyone from the Realm to be transformed, that's what the stories said anyway.  Rhett had corrected her and said while over 50% of the Realm was transformed, the vast majority were women.

            Daily run ins at the coffee shop had eventually turned into a date.  Lorraine had been flabbergasted when Rhett asked her out.  She was, to put it politically correctly, big boned.  At five foot ten and nearly two hundred pounds, Lorraine was anything but the dainty feminine stereotype.  While her bulk came in handy as a veterinarian's assistant, it tended to scare away potential dates.

            Ironically Rhett had the same problem in reverse.  He was very short for a guy, only an inch or two above five feet.  When Lorraine pointed this out, Rhett only smiled and said all the males from his village were below average in the size category, while the women were big and bountiful.  It was one thing that had attracted him to Lorraine; she reminded him of home.

            Of course, that wasn't the whole story.  Rhett hadn't shared that until their third month together, by which point Lorraine had begun considering she might spend the rest of her life with the man.  When Rhett had shown her pictures of the other women back home, she'd been flabbergasted.  And a bit offended.  Rhett didn't love her the way she was?  He wanted her to change into something like that?  No, she wouldn't do it.

            That revelation had led to the couple's first fight.  Lorraine had stormed out and swore she wouldn't see Rhett ever again.  To his credit, her ex-boyfriend gave Lorraine all the space she needed.  All he did was leave a folder at her place a week later, labeled Please think about it.

            Lorraine had tossed the folder in the corner and forgot about it for nearly a month.  It was only when she was shredding the week's mail did she stumble back across it.  Lorraine was tempted to shred the pages inside as well, but curiosity stopped her.  By that point, Lorraine was already regretting how she'd blown up at Rhett.  He'd been very up front about how all the women back home were transformed and that he was going home at the end of his exchange.  Lorraine had just been too blind to make the connection that if she followed him home, she'd end up transformed as well.

            And so one evening Lorraine sat down and read through the contents of the folder.  It was the dissertation Rhett compiled about the women of his home village and how integral they were to the health of the community.  Without them, the village would have had to surrender to the times and buy some of the Empire's fancy farming machines in order to maintain their lifestyle.

            Lorraine read through the whole document, then set it aside.  Two hours later, she did it again.  She read it every night for a week, the idea slowly becoming more and more appealing.  Lorraine had always loved animals, it was the reason she became a vet's assistant.  She hoped to one day save up enough money to go to veterinary school herself and open her own shop.  What Rhett offered was unexpected, but didn't diverge too much from the spirit of her life plan.

            Eventually, Lorraine found herself on Rhett's doorstep one night.  When he answered Lorraine held out the folder and said, "I'm sorry."

            Rhett had smiled, the little smile that melted Lorraine's heart every time she saw it.  He reached under his shirt and pulled out a small vial of while liquid on a silver chain.  As he set it in Lorraine's hand he said, "I knew you would come around.  I had this made for you, for when you were ready.  I want you to be my wife."

            Lorrain slowly lifted up the vial, examining the white liquid within.  The liquid with the power to make her into one of the women of Rhett's village.  A liquid that would change her life forever.

            "I don't know what to say." she stammered.

            Still smiling, Rhett replied, "Just say yes."

            After another heartbeat of contemplation, Lorraine had.  And that was how, six months later, she found herself here today.  A day that would change her, and her life, forever.

            "It's time."

            Lorraine spun around to find Kyrega, Rhett's youngest sister, had entered the tent behind her.  The young woman was one of the few untransformed females Lorraine had met since moving to the Realm.  Then again Kyrega was barely sixteen, too young to change even in the Realm.  From their conversations at dinner the night before, Lorraine knew Kyrega was already planning her own wedding day.

            "You look so beautiful.  Rhett is a lucky guy." Kyrega said as she came to stand beside Lorraine.  The young woman was nearly Lorraine's equal in size, a dozen pounds lighter but an inch taller.  Lorraine had discovered Rhett hadn't been lying about the members of his village being big girls.

            Kyrega held out a hand and Lorraine took it, letting the younger woman pull her out of the tent.  From then on the ceremony was a blur of faces and emotions.  Lorraine finally came back to herself at the center of a crowd of people, having just kissed Rhett for the first time as husband and wife.  It would be her last kiss as a regular human.

            Lorraine's dress had a strategic opening at her breasts, allowing Rhett to reach in and unhook the vial.  He took it, kiss the diamond lid, and passed it back over to Lorraine.  As he did, Rhett whispered, "Thank you for making me so happy.  I hope this change will do the same for you."

            Lorraine took the vial and studied it one last time.  The liquid within had hung next to her skin for almost half a year, soaking up her essence.  Soon it would be inside her, modifying Lorraine's body so she could stand proudly as a member of the village.  With a nervous smile at Rhett, Lorraine carefully unscrewed the lid.  There was a small pop as the seal broke and the liquid within was open to the air for the first time since it's crafting.  Lorraine gave it a gentle sniff and was almost disappointed that she couldn't smell anything but the fresh grass the of the field they were standing in.  Something this powerful should have had a smell.

            Resolute in her actions, Lorraine held the vial to her lips, tipped it up, and drank the contents down.  The liquid had a taste, but it was hard to describe.  Kind of milky, mixed with fresh cut grass and vanilla and love.  Lorraine wasn't sure that love actually had a taste, but somehow the potion gave off that impression.

            Lorraine didn't have to wait long for the potion to take effect.  She knew what was coming, had seen another women in her place at a wedding not two months ago.  As her entire body began to tingle with warm energy, she undid the clasp on her dress and let pool to the ground at her feet.  One of the little flower girls swooped in and snatched it up to keep the fabric out of the way.

            Before Lorraine could grow nervous about being naked before a crowd of people, she felt herself begin to swell.  Not with pride, but actually grow.  Lorraine's limbs began to grow thicker, bulging with fat and muscle.  The world seemed to shrink as she grew in height until Lorraine towered over the man standing beside her.

            It was then the inhuman changes began to present themselves.  Lorraine's bust, already large for her size, swelled up like pink basketballs.  Underneath, Lorraine could feel the flesh move as two more spots poked out of her chest.  These grew as large as those above, leaving the bride with four massive breasts hiding most of her torso.  The nipple of each underwent mitosis, splitting apart into four points.  Each nipple point swelled rapidly, transforming into four teats the size of Lorraine's thumbs.

            These were the first of Lorraine's bovine changes, but they weren't the last.  A short coat of white and black fur formed around the bride like a skintight bodysuit, both covering everything and concealing nothing.  Still, it did reduce Lorraine’s feelings of nakedness.  Lorraine's feet shrunk and hardened, becoming cloven hooves.  While her hands grew thicker the fingers, now topped with a heavy black nail apiece, remained separate.

            Lorraine held one changed hand up to her face, examining her new blunt fingers, as her face began to change.  The area around the mouth pushed out, leaving Lorraine with a short muzzle.  Lorraine's ears itched, and she reached up with a hand to find them larger than before.  They stuck out the side of her head, barely corralling her thick mass of hair.  There were two instantaneous pinpricks of pain as something pushed out of the skin.  Lorraine reached further up and found she now possessed two small horns poking out just below her hairline

            The final change happened just above Lorraine's crotch.  The skin of her lower stomach bulged out, much like it had with her second set of breasts before.  Only this pouch of skin wasn't satisfied with the size of a basketball.  By the time Lorraine's new udder had grown into place, the old her could have easily used it for a bean bag chair.  The eight teats running down the length like dual rows of spikes were the size of her husband's arm, the tips gleaming with the first hints of white milk.

            As the last of the potion’s magic burned its way out of her system, Lorraine felt herself stabilize.  She didn't need a mirror to know what she looked like, Lorraine's form was mirrored by all the women in the crowd over the age of seventeen.  She was an anthro cow, a massive anthro cow.  Eight feet tall at least, and massing somewhere in the neighborhood of half a ton.  While that weight would crush a normal human, Lorraine's new muscles left her feeling almost dainty.

            Lorraine felt a warm hand on her udder and looked down.  It was Rhett, smiling up at her.  He looked positively tiny now, a good three feet shorter than his bride.  Wordlessly, he mouthed, "You're so beautiful."

            Lorraine almost said something back, but she was interrupted by the priestess who performed the wedding vows.  Like Lorraine she was and anthro cow, but she seemed to have taken on more bull characteristics.  A massive pair of horns, easy three feet wide, grew from the woman's temples.  Instead of an udder, the priestess possessed a dick and balls of comparable size.  Now that she thought about it, Lorraine had a sneaking suspicion she knew where the liquid that transformed her had come from.

            "It is now time to complete the ceremony." the priestess proclaimed.

            Rhett was way ahead of her and had already divested himself of all clothing.  Lorraine leaned forward, bending nearly in half to share a kiss with Rhett.  As she rose back up, her naked husband got down on his knees and crawled behind her udder.  Lorraine felt fingers rub against the edges of her vagina and unintentionally let out a moan of pleasure.  Lubrication gushed from her lips, allowing Rhett to gently slide one hand up inside her.  Another followed in quick succession, dilating Lorraine in a way she’d never experienced before.  There was a pressure and suddenly Lorraine felt incredibly full as her husband pushed his way up inside her.

            While Lorraine had read and reread this section of the dossier, she'd never understood the practicality of how the people of the village had sex.  Clearly the missionary position was out; no human male could satisfy a woman of Lorraine's size.  It was only now, as she carried Rhett in her belly, that Lorraine understood.  It fostered a relationship akin to mother and child.  It also didn't hurt that the process left every nerve ending in Lorraine's body singing in pleasure.

            Lorrain turned at heavy steps behind her.  Striding toward her was Lyketa, Rhett's mother.  The cow woman was just as large as Lorraine, her stomach bulging as she carried her own husband.  The men of the village spent a lot of time in their wife's bellies.  A special organ in there supplied the necessary air and nutrients, while allowing them to still experience the world around them.

            "Welcome to the family Lorraine." Lyketa called, enveloping the other woman in a hug that sent squished breasts and udders in all directions.  "Rhett certainly chose well when he picked you.  You will be a welcome addition to our village."  Lyketa leaned in closer and whispered, "And I can't wait until I have some of my own grandchildren to play with."

            Rhett shifted inside her, causing Lorraine to almost orgasm on the spot.  Would it be like that, when she held children in her belly instead of her husband?  Lorraine hoped so, as life would become a constant orgasmic haze.  She smiled.  A new husband, a new form, a new life.  Things could only get better from there.

And here's my last story for Valentine's day 2018.  It ended up a lot longer than I expected.

            Caleb stepped through the front door of his house and set his briefcase on the counter with a sigh.  After another long week in sales, he was ready for the weekend.  Caleb paused to look in the mirror next to the front door, soaking in his reflection.  His short hair was more grey than black these days, and the wrinkles were even deeper.  Caleb looked fifty, not thirty-eight.  If he didn't change careers soon, the stress would kill him.

            "Honey, I'm home." Caleb called out the traditional greeting as he pulled himself away from the mirror.

            "I'm in the family room." Caleb's wife Kristi called.  "There's lasagna warming in the oven.  Grab a slice and come join me."

            Caleb's stomach rumbled at the mention of food.  Still, it wouldn't do to risk getting pasta sauce on one of his good shirts.  A quick change and some knife work later, Caleb settled onto the couch beside his wife.

            Caleb had met Kristi in college, though they were both dating someone else at the time.  They crossed paths several times over the next five years, until circumstances finally allowed them to date.  Looking back, Caleb missed those early days.  He still loved his wife dearly, but the spark, the passion of two people madly in love just wasn't there anymore.

            It wasn't like Kristi had suddenly gotten fat and ugly over their seven years of marriage.  Her job as a personal trainer kept Kristi fit and healthy.  Her hair was still long and blonde, kept up in a ponytail no matter if she was at work or at home.

            A decade ago, when they first started dating, the first thing Caleb would have done upon arriving home was sweep his wife up in his arms.  Now all he wanted was some food and to get off his sore feet.

            Settling down on the couch, Caleb gestured to the TV with his fork.  It was currently in the middle of a commercial for a drug to cure male pattern baldness.  "What are you watching?"

            "There wasn't anything good on, so I went channel surfing."  Kristi shifted over to give her husband more space on the couch.  "I stumbled across this weird infomercial show."

            "Weird how?" Caleb asked, before taking the first bite of his dinner.

            "Transformations.  Stuff I've never seen anything like before."

            "What, like lose twenty pounds in two weeks type products?"

            "No, like gain the ability to grow three feet taller transformations."

            Caleb froze, his fork halfway to a second chunk of lasagna.  If the first had still been in his mouth, he would has spit-taked.  "Say what?"

            Kristi chuckled.  "I know, I didn't believe the premise at first either.  But I've been watching for nearly an hour and the results have been unreal."

            "Something you have to see to believe."

            Kristi nodded.  "Pretty much.  It's this company called InnerU.  Somehow they came up with a way to allow people to change characteristics about themselves, then change back."

            Caleb continued to look skeptical.  "How do they do that, magic?"

            "Complex biological processes, apparently.  The initial changes to the body might be like magic, but switching between the two forms is fairly basic.  For example, the first guy they showed had a weight gain fetish.  The treatment they gave him allowed his body to swell up nearly three hundred pounds heavier."

            "You can't just pull that mass from thin air.  It had to come from somewhere."

            "Oh, it did."  Kristi assured him.  "It was all water weight.  They put him in a tub…more like an inflatable pool actually, and he swelled right up.  The initial changes gave him internal pockets to store the extra liquid and the musculature to carry the weight.  It wasn't a perfect change, but by the end he truly looked like a morbidly obese man."

            "Did they change him back, or is he stuck that way forever?"

            "The man was one of their early test volunteers, so the shrinking method wasn't as efficient as it could have been. They pretty much stuck him in a sauna for a half hour and he sweated all the water out.  One of the techs told them it beat their initial idea, which would have left the poor guy stuck crouching over a toilet pissing for hours."

            "Unreal.  To think they could do something like that to the human body.  Is it some kind of surgery?"

            "No, they said something about a genetic augmentation retrovirus.  Apparently they didn't create the changes from scratch, they extracted them from other species and figured out how to splice them into human DNA.  I think they said the growth sacs came from some kind of sea creature."

            "Unbelievable.  What other transformations did they do?"

            "The next woman they brought out was able to change herself into some sort of plant creature.  Her skin turned various shades of green and bark like growths poked out in a few places.  The oddest changes were to her limbs.  Her bones were able to segment, turning them more into vines or tentacles than what we normally think of as limbs.  The one after that was able to grow his hair as ridiculous rates.  Not just head hair either.  He walked out on stage completely bald and by the time they were done with him the man could have passed as bigfoot."

            "Not a change I image most people would want to buy." Caleb remarked.

            "Full body, probably not." Kristi agreed.  "But just for head hair, it allows the transformee to go from nearly bald," she rubbed her husband's close cropped hair, "to luscious locks in only a few minutes."

            "Good point.  What was the next change?"

            "It was some woman who wanted to grow smaller.  They made changes to her skeletal and muscular structure, allowing it to compress and expand.  She was already short to begin with, just below five feet, but they were able to drop another foot off her height without changing proportions drastically.  The result was almost creepy, adult proportions on someone the size of a child."

            Caleb nodded as he tried to picture the change.  Thinking better of it, he instead had another bit of lasagna.

            "I'm glad you got home in time, as they've been hinting about this change for the entire show.  I think you'll really like it."

            "Oh, why's that?"

            Kristi grinned evilly.  "Do you remember your pink box?"

            Caleb nearly dropped his fork, his ears turning crimson.  Before meeting Kristi, Caleb had gone through such a dry spell he decided to experiment with crossdressing.  Something about scratching the itch for some femininity in his life.  After things with Kristi had gotten serious he'd stopped doing it, putting all his girly things in a box at the back of his closet.  There it had stayed, until the new couple finally decided to move in together.  During the move Kristi had found Caleb's stash and…things had gotten interesting.  All things considered it could have gone much worse, but Caleb was still embarrassed the few times Kristi brought up his gender curious past.

            "Relax honey, I'm not mad or anything.  That one time you lost a bet and I made you dress up as a maid was adorable."

            Caleb didn't respond to that.  He'd been humiliated the whole weekend, but secretly enjoyed every second.  Luckily for him, the string of commercials ended and the main show came back on.

            "Welcome back everyone." the show's host proclaimed, looking surprisingly ordinary for the extraordinary products he was hocking.  Caleb could have passed the man on the street and not given him a second glance.

            "What we're about to show you it what we predict to be one of our most sought after products.  Please give it up for Tommy, who will be demonstrating our InnerSlut package."

            The crowd clapped as a young man strode out onstage.  Much like the show host there wasn't much to distinguish him.  Average height, short black hair, skin pale from too little time in the sun.  He could have passed for a fifteen year younger version of Caleb.

            "Tommy, why don't you tell us a little about yourself?" the host said as the demonstrator approached center stage.

            "Um…hello." the man waved nervously.  "My name is Tommy, and ever since I was young I've had a fascination with women. Not the way a normal man going through puberty would, I wanted to be one instead of date one.  I wanted their grace and raw sexuality in ways I couldn't express.  I experimented with cross-dressing and considered going through the gender reassignment process, but they couldn't give me what I wanted.  Until I found InnerU."

            "We're glad to help Tommy, especially with you giving back by helping us demonstrate our products.  While the InnerSlut switch doesn't require as much mass gain as the InnerGiant, there's enough moving around its best performed with a water source handy."

            The host gestured to a portable shower that they wheeled onstage.  Tommy took this as his queue and began undressing.  Caleb was surprised to see the young man looked just as ordinary under his clothes.  About the only oddity, apart from the near total lack of body hair, were his oversized nipples and areola.

            "I thought the changes would make him look different." Caleb confessed.

            "InnerU strives to make the changes discrete, at least that's what they said earlier.  Some things can't be hidden though.  The stomach of the weight gain guy earlier looked like an accordion.  He needed the extra skin to expand.  But you couldn't tell with his clothes on.  The plant girl had some dark spots where the bark poked out, but she actually hid them in the designs of the tattoos that covered her body."

            By this point Tommy had divested himself of nearly all this clothes.  What remained was a loose fitting Speedo that maintained his modesty.  This was cable after all.  The host gestured at the shower again and Tommy stepped inside.  It was a waterfall design and after the door was shut water rained down from the ceiling.  There must have been cameras attached to the walls of the shower, as the TV zoomed in for a close up of the change.

            As Tommy ran his hands up and down his body, it became obvious his mass was being redirected.  Tommy's waist, while already small, narrowed to Barbie doll proportions.  While some of the mass floated upward, creating B-cup breasts, the majority went to the transforming man's hips and butt instead.

            Unexpectedly, as the water continued to rain down Tommy's skin began to darken.  Each drop seemed to peel off another pale layer, until shade by shade Tommy turned a rich caramel color.  The hair on his head remained black, growing out in thick, curly ringlets.

            After five minutes, the water in the shower shut off.  A nervous, skinny white boy had stepped in.  What stepped out was a confident, solidly built black woman.  The Speedo that had once been loose was now stretched skin tight over thick thighs and a plump backside.  Surprisingly, this revealed that Tommy had kept a male member despite all the other changes.  Imprinting badly against the transformee's right leg, it looked even larger than before.

            Tommy accepted a towel from a stagehand and used it to wipe the moisture from his…how her body.  After a quick pat down of her hair, the newly gender changed woman handed back the towel with a quiet thanks to the stage hand.  Striding confidently to center stage, she proclaimed, "Hello again everyone.  I'm Tammy, Tommy’s feminine alter-ego.  It feel so good to slip out of the nasty shell of masculinity.  As least mostly."  Tammy reached down and ran a finger along the length of her scandalously exposed penis.  "InnerU could have given me a pussy with my change, but it wouldn't be functional.  Just a hole, nothing more.  I decided to stick with a functioning member until they get the bugs worked out of the InnerHerm package.  Besides, my clients go wild when they find out my little secret."  Tammy let out a girlish giggle.

            Caleb couldn't help himself, he was as hard as a rock watching the feminine creature prance around onstage.  Such a thing should have been impossible, yet the proof was undeniably before his eyes.  Turning away from the screen, Caleb's eyes fell on Kristi.  Instantly he felt guilty.  As much as he wanted to be the sexpot on the TV, such a change would drive a wedge between them.  As far as Caleb knew Kristi was straight, even retaining his member like Tammy probably wouldn't be enough to keep her.

            As if sensing his inner conflict, Kristi put a hand on Caleb's knee.  "You want to be her, don't you."

            "N…no." Caleb stammered.  The words sounded false even to him.

            "Really?  It seems a certain part of your anatomy disagrees."  Kristi's hand moved closer, tracing the outline of where Caleb's dick was tenting his sweats.  Caleb almost came right then and there, on the edge just as Kristi stopped her ministrations.  "Oh, I see.  She's not busty enough for you.  I forgot you liked real backbreakers.  Those breast forms you had were what…DDD cups?"

            The truth was closer to G cups, but Caleb wouldn't admit it.  Kristi was right though, every time he drifted off to sleep thinking of being a woman, she possessed a pair of tits that would make a pornstar jealous.

            "I'm sure they could make a version with a bit more on top." Kristi continued.  "After all, if they could make it so that guy gained a couple hundred pounds, how hard would it be to staple a couple of bowling balls to your chest?"

            "I…can't…" Caleb said softly.

            "Why not?  This is what you've always wanted, isn't it.  A chance to life out your ultimate womanly fantasies on a part time basis.  What's holding you back?"

            Caleb's head sank.  Unable to look his wife in the eyes, he mumbled, "It would mean losing you."

            There was dead silence for a good ten seconds, before Kristi burst out laughing.  Caleb looked up in confusion as is wife nearly fell off the couch in her mirth.  When Kristi finally regained control of herself, she leaned in and kissed Caleb on the cheek.  "You're sweet Caleb.  It warms my heart to know you would give up your dream to be with me.  But if we're honest, the spark between us has dimmed a bit over the past few years."

            "Does that mean that…that you don't love me?" Caleb asked hesitantly.

            "No silly, of course I still love you."  To accentuate her point, Kristi leaned in and gave Caleb another kiss, this time on the lips.  "But all things, be it bread or relationships, become stale over time.  I see this as a chance to give our spark a bit of a jump start."

            Relief flooded through Caleb like a cleansing rain.  Maybe he wouldn't have to choose between his desires and the woman he loved most in the world.  "You'd do that for me?  Be with another woman…err mostly woman."

            "Sure, as long as you don't mind living with a man."  When Caleb looked confused Kristi added,  "We have to keep things in balance.  If you're going to get to explore your feminine side, I want the chance to see what's so cool about muscles and body hair and other guy things."

            "I didn't realize…"

            "Nor did I.  But I consider it a small sacrifice to still be with you.  Besides, I think leading double lives as a different couple could be fun.  Think of the combinations we can experiment with."  Caleb did, and the resulting thoughts made him nearly cum right there.  "One final question.  Just how big do you want your breasts to be?"

            Caleb couldn't answer that due to all the blood flowing from his brain to a different part of his anatomy.  Seized by a sudden inspiration, Caleb set aside the remains of his dinner.  He got up off the couch and pulled up Kristi after him.  Bending at the waist, Caleb picked up his wife in a fireman's carry and started toward the bedroom.  Tomorrow he'd be sore from such an action, but tonight the couple were going to make love like they hadn't in years.

_________________________________________________________________

            "Are you ready?"  Kristi asked, kissing Caleb on the cheek.  "Our big moment has finally arrived."

            Ever since watching the InnerU infomercial, it was like someone had poured gasoline on the fire of their relationship.  They were having sex, if not nightly, then at least five times a week.  That was, until last week, when the pair finally went in for their treatment.  Caleb had expected something elaborate, giant glass tanks of floating people or dips in baths filled with unknown chemicals.  Instead InnerU was much like a standard doctor's office, including nurses giving shots.  As the perky redhead depressed the plunger on the vial containing the retrovirus with Caleb's specifications, he wondered what her change was.  Weight gain, extra breasts, even more perkiness?  Or was this her changed form, and she used to be some overweight guy?

            The doctor told them the changes would take a week to percolate through their bodies.  While some changes could be ready to go in less than a day, gender flips required significant supporting modifications.  It didn't help that Caleb and Kristi had selected InnerUs with radical mass and size changes.  Each had kept the specifics secret from the other, for a bigger surprise at the final reveal.

            For Caleb, the next week felt like the worst cold in his life.  He was achy everywhere, from his toes to the crown of his head.  The pair had already scheduled a few vacation days for when their changes would be ready, but were each forced to toss in a few sick days on the front end as well.  So the couple passed the time sitting together on the couch, snuggled up with blankets and watching old movies.  It was nostalgic to when they first met, just without the flu symptoms.

            Luckily, the side effects cleared up that morning.  Caleb and Kristi had planned things so their transformations would be ready on Valentine's day.  A perfect symbol of their rekindled love, and the new love of their other selves.  After a day of walking though museums and art galleries, followed by a night with a dinner at a nice restaurant, it was finally time for the moment they'd been waiting for.

            Like everything else, the couple had a plan.  Both changes would require showers or baths due to the mass changes.  However, their condo only had one shower.  Therefore Kristi would take hers first, while Caleb waited downstairs in the living room.  Once she was done changing, Kristi would move into the room they used for storage and a small office.  At this point she'd text Caleb he was free to begin his own shower.  Caleb would send a text back right before he stepped into the water, letting Kristi know she was free to return to the bedroom and wait for him.  It was a bit of a Chinese fire drill, but would allow both to switch over to their inner selves while keeping the results a secret.

             "I am." Caleb replied, his mind snapping back to the present.  "I can't wait to see you in a few minutes."

            "You won't." Kristi said over her shoulder as she walked upstairs.  "You'll be seeing someone new."

            The following twenty minutes were the longest of Caleb's life.  After wearing a hole in the floor pacing back and forth, he tried turning on the TV and catching up on some news.  But the words passed by in a blur.  Caleb's mind was too focused on what was happening upstairs, picturing his wife's body changing in a dozen different ways.  Caleb knew his wife's InnerU form was male, but that was it.  Would he be tall or short, thin or solidly built?  Would she go for another ethnicity, or maybe another age range?

            Caleb was so caught up in thought he jumped in surprise when his phone beeped.  Scooping it up, Caleb saw he had a text from Kristi.  The message was short and sweet.  Your turn.

            Caleb nearly sprinted upstairs.  He skidded into the bedroom, discarding his clothes next to Kristi's on the floor, before stepping into the still damp shower.  His dick preceded him like a flagpole on a windy day, already hard at the thought of the transformation that had just happened and the one to come.  Caleb could almost feel the masculine presence that had left here only a few minutes before and longed even more to wash his own masculinity away.

            Stepping into the shower, Caleb twisted the knobs to send water pouring down on him.  While the liquid was important, it wasn't the only piece required for the transformation.  Otherwise, Caleb would accidentally transform every time he took a shower.  The horniness helped, but it too wasn't the missing piece.  Closing his eyes and clearing his mind, Caleb focused on what the doctor had told him at the clinic.  He had to picture his inner self, the one he wanted to change into.  This would release the hormones that would jump start the switch.

            Pushing all other thought from his mind, Caleb focused on his inner slut.  Her tiny frame with its massive breasts.  Long silver hair framing a face just begging to be kissed and then fucked.  A rock hard dick, even larger than the one he had now, just begging to be stuck into something warm and wet.  A libido that couldn't be satisfied, no matter how many times she fucked.

            The water flowing down around him was only lukewarm, but Caleb suddenly felt very hot.  This was it, the big moment.  His body was switching over to his inner slut.

            Caleb opened his eyes to find the shower controls were a lot higher than they were a moment before.  But it wasn't just the controls, the shower head was higher too.  And the handle for the glass door.  It was then that Caleb realized the shower wasn't bigger, he was shrinking.

            According to the doctors, it was much easier to grow a patient than shrink them.  The processes were much the same only in reverse, but there was still a minimum amount of mass require for the human body to function.  Caleb was five-ten and the doctor said the safest he could shrink was five-two.  Two of those eight inches came out of Caleb's lower legs, two from the upper, three and a half from his torso, and the last half from his neck.  Caleb's long bones had hollow sections like a collapsible baton.  In his male form they were full of fluid to provide structural support, but the switch vented the fluid to allow them to collapse.  The two inches were broken up into a dozen smaller slips, to reduce the risk of structural defects and still leave space for the other things needed in Caleb's bones (like marrow).

            Caleb stretched as he felt a popping sensation in his back.  According to the doctor, this shrinkage was more complicated than those on his limbs.  Three of Caleb's vertebrae actually popped out of the way, allowing the bones above and below to still carry a structural load.  This was even more complicated in Caleb's neck, so in that case one of the vertebrae simply was sucked up into the skull.  Said skull was also shifting slightly, sanding off some of the masculine traits such as heavy brow ridges.

            As his skeletal structure stabilized, Caleb felt his muscles and fat begin to shift.  Caleb could feel the water soak into his skin as his thighs and butt began to plumpen.  An earlier shift in his pelvic structure had left plenty of space for the extra mass to connect to.  As it would be difficult to shrink Caleb's stomach any more, he'd decided to acquire an hourglass figure by thickening up both ends.

            Speaking of ends, Caleb's hands rose as his chest began to tingle.  When Caleb first told the doctor how big he wanted his breasts, the man had blinked blankly at him for a good ten seconds.  He then told Caleb to wait a minute and went to go make a phone call.  Upon returning, the doctor told Caleb the boys in the lab were actually testing a new code sequence for super stretchy skin.  They'd intended it for weight gain clients, so they wouldn't need to go around looking like an accordion when in light form.  Using it on Caleb's breasts would be a good field test, as it would be localized and easier to tune compared to a full body application.  If it worked as well as they thought, the only limit on Caleb's breast size would be the musculature required to carry them.  Caleb had no plans to become the next Chelsea Charms, but the size he selected could double as soccer or bowling balls in a pinch.

            Caleb cupped his new breasts, enjoying the feeling of them growing before his very eyes.  Caleb had experimented with large breast forms back during his crossdressing days, but there's nothing like the realization that the massive bags of flesh in his hands were actually part of him.  Caleb enjoyed the sensation so much he nearly came right there in the shower.  With herculean willpower, he managed to resist.  Caleb wanted his first orgasm to be with his wife.  After that…who would blame him for a few special moments in the shower.

            Reaching down, Caleb tried to shift his dick into a more comfortable position.  The source of the discomfort turned out to be that his glans was pushing into the shower wall.  Trying not to set off an orgasm, Caleb let his fingers trail down the entire length.  Holy hell, he was now hung like a horse.  Caleb knew that both the male and female slut packages received genital enhancements, but this was ridiculous.  Even taking into account the skewed perspective from shrinking over half a foot, it felt like a summer sausage was swinging from his crotch.  The testicles hanging fully loaded underneath had to be the size of apples.

            Caleb pulled his hand away, knowing that any more exploration would lead to premature ejaculation.  It was pointless trying to see his dick around his massive breasts, so Caleb leaned back against the shower wall and let the rest of the changes overtake him.

            With the heavy stuff out of the way, only the little details were left.  Caleb felt his lips tingle as they plumped out into the perfect cocksucker orifice.  Though he couldn't see it, Caleb knew they were now an eye catching crimson red.  A similar shade decorated the top of his eyes, eyeshadow that Caleb would never need to worry about messing up.  The tech who did skin markings was very enthusiastic and Caleb had ended up with more than the basic make-up package he'd initially pictured.  A ring of pink roses encircled his right ankle while a tramp stamp of bold black lines appeared on the small of Caleb's back.  It read K's slut.

            Finally the feeling of warmth faded and Caleb realized his switch was over.  Turning off the water, Caleb reach for a towel.  He undershot and almost smacked the toilet instead.  A second try proved more successful and Caleb quickly wiped the moisture from his body.  His thick silver hair would need a little more work, but it could wait.  Slinking over to the mirror, Caleb used what little dryness remained in his towel to wipe away some of the fog on the mirror.  When he saw what was reflected there, Caleb finally lost the battle with his arousal and came all over the floor.

            There was no hint of Caleb in the reflection.  There was only Casey, his inner slut.  Face that could launch a thousand ship, body that would keep men coming back until they died of exhaustion.  She didn't look to be older than her late twenties, but carried a confidence of someone who knew what she wanted and exactly how to get it.  Much like with Tommy/Tammy on the infomercial that started it all, Caleb found his mind taken over by his feminine half.

            Casey smile as she took in her reflection.  Yes, she had turned out better than Caleb had expected.  Hopefully he would let her out to play often, it would be a shame to waste such a good looking inner self.  Looking down, Casey spotted the mess she'd made for the first time.  Opps, she'd need to clean that up later.  But first she had a more pressing issue to deal with.

            Carefully, Casey tiptoed over to the door.  Caleb had designed her feet for neck breaker high heels and her tendons had shifted to compensate.  The downside was she couldn't put her heels down anymore.  While this wouldn't be an issue while clothed, Caleb had failed to consider the periods of time Casey would be in the buff.  Something she might need to fix on a later tune up.

            Pushing open the bathroom door, Casey surveyed the room beyond.  Kristi had been busy in her absence.  The clothes on the floor were gone, replaced with red flower petals.  The lights were lowered, augmented by wavering candles and low jazz coming from the stereo.  "Honey, I'm home." she called.

            "I'm on the bed." a deep, masculine voice growled.  "Why don't you come and join me."

            In the reduced illumination it took Casey a moment to spot her target, and when she did the slut's confident jaw dropped.  Laying on the bed propped up against the headboard was an enormous black man.  If this was the new Kristi, she'd picked up Casey's lost eight inches and then some.  Even laying down, it was easy to tell the man was on the upper half of the six foot range.  Then there were the muscles.  Each one stood out in perfect definition, as if oiled with tender care.  The man on the bed looked strong enough to use it as a weight set.

            Casey tottered over to the bed and climbed up to sit beside the object of masculine perfection.  Up close she had a better look at his features.  Craggy and solid, no trace of Kristi's former beauty.  Casey might have thought that Kristi brought in a ringer, until she glanced between the man's legs.  A specimen this size should have had a dick bigger than Casey's salami, but all that existed between the man's legs were some wavy chocolate brown lips.  They reminded Casey of cake toppings and she had to resist the urge to dive in for a taste.

            "Hey big boy." Casey said in her sweetest voice.  "I'm Casey.  What can I call you?"

            "Karl."  the deep voice rumbled.  "Or, the one who will be making you see stars all night long."

            Suddenly Casey found herself airborne.  Karl had gotten up off the bed and taken Casey with him, carrying the slut like she was a child's doll.  When Karl stopped before the mirror Casey saw it was an apt comparison, she was positively tiny compared to the man holding her.  Instead of fear, Casey found herself aroused.  She was completely at the mercy of Karl, a toy for him to use and abuse as he saw fit.  At these thoughts Casey's dick stirred, rising up to poke at the mirror.

            Karl chuckled when he saw Casey's arousal.  "Ah, my little slut is finally rising to the occasion.  I would have thought you hot and ready upon exiting the bathroom."

            "I accidentally made a mess while getting out." Casey admitted.

            "Is that so?  I guess that makes you a bad girl.  And bad girls must be punished."  Casey's entire world spun and she found herself upside down.  Karl's vagina was right in her face, the smell of the man's arousal making Casey lightheaded.  "As you've already had an orgasm, it's only fair you pleasure me before we move onto the main event."

            That was all the invitation Casey needed.  Her tongue shot out, licking Karl's lips like they were chocolate candy and she was a sugar crazed schoolgirl.  Casey's entire world shuddered as she stuck her tongue deeper inside Karl's folds, the man's trembles transferring down to her.  Casey was about to go deeper when she found herself spinning around again.  This time she was face to face with her lover.  "That was an excellent start pet.  Why don't we return to the bed before I accidentally drop you."

            Karl lay back in the center of the bed and spread his legs wide.  "Service your master, pet."

            Casey crawled up between Karl's legs, about to lick at him some more, but stopped when she saw the look on the man's face.  He clearly wanted more.  In that case…

            Casey repositioned, aligning her massive dick with Karl's dripping hole.  They both moaned in pleasure as the tube entered the slot.  "Fuck me." Karl cried.  "Fuck me like the little bitch you are."

            "You're on, big daddy." Casey giggled, before ramming herself in extra deep.

            Both lovers lost themselves to animal passion at that point.  Karl grabbed one of Casey's massive breasts and pulled the nipple to his mouth.  His sucking on the tender flesh drove the slut wild.  Casey took pleasure in outlining Karl's extensive musculature with her tongue, while her lover jerked her cock and tickled her huge balls.

            The pair came together, came apart, came over and over.  Far past the point normal humans would have collapsed dead of exhaustion, the pair lay together enjoying the latest afterglow.  Casey was in Karl's lap, her head resting on his pecs like they were pillows.  One of Karl's hands tickled his lover's finally flaccid dick, while the other rubbed circles around a nipple.

            Looking over at the clock, Karl saw it was just after midnight.  "That was one hell of a Valentine's day." he said, mostly to himself.  By her breathing, Casey was in a light doze.

            Or apparently not, as she answered, "I had fun too.  Can we do it again tomorrow?"

            "You mean today slut, tomorrow is already today."

            "Ok big daddy, later today.  But first, I need some sleepies."

            "Of course my pet.  Rest well.  Tomorrow will be another busy day."

______________________________________________________________________

            Several days later, as Sunday drew to a close, it was Caleb who stepped out of the shower.  The world around him seemed alien, too small.  Even though he'd only been Casey for a few days, it felt like she was the real him and Caleb was just a mask.

            Coming out of the bathroom, Caleb found his wife cleaning up the bedroom.  Even though they were the same person, it was hard to reconcile Kristi and the muscular Karl.

            "Hey, how do you feel?" Kristi asked as she pulled sheets off the bed.  If these sex filled switches were going to continue, the couple were going to have to invest in more bedware.

            "Like I'm waking up from a perfect dream." Caleb replied.  "I don't know how I'm going to go to work tomorrow."

            "I know how you feel. I'm going to see all those weights and think about how easy it would be to lift them as Karl."  Kristi's face turned mischievous.  "I know I said we should only play on the weekends, but I have a client who's going out of town on Wednesday.  Why don't you get out of the office a little early and we let Karl and Casey have a dinner date?"

            It was Caleb's turn to smile.  "I'd have to ask her, but I'm pretty sure Casey would be in if you could talk Karl into coming."

            "Oh, he'll be there.  Now, I know these are our last sheets, but how about another round?  After all, we can't let those two have all the fun…."

______________________________________________________________________

            Epilogue-One year later

            Casey stood before the bathroom mirror, drying her hair with a blow dryer.  It was hard to believe that it had been almost a year since Caleb had temporarily ceased to be and Casey had come into existence.  At first she and Karl had been kept for love making weekends and the occasional midweek nookie, but soon they got to come out to play more and more.  It had taken two months before Caleb and Kristi had worked up the nerve to go out in public as their alternate selves.  Oh what a night that had been.

            By the six month point, Caleb and Kristi were spending more time as their alter egos than as themselves.  Caleb would come home from work and immediately shower into Casey.  He'd cook a nice dinner for Kristi/Karl, who was working longer hours to make up for Caleb cutting back.  A meal, a nice fuck, and it was time for bed.  The next morning Casey would take an early shower to turn back into Caleb before rushing off to work.

            Then the recession hit.  Caleb had held onto his job, but only enough hours to work three days a week.  It was then Casey took over with her own special brand of marketing.  The pair already owned a large sex toy collection, a side effect of needing to satisfy two massive libidos.  Casey started using them to make internet videos.  Not the porn kind, those were plentiful and free.  No, she made demonstration videos.  Casey would put a toy through its paces, demonstrating ways to use it for maximum advantage and all the little things she liked or disliked about it.  Occasionally Karl or Kristi would join in for scenes that required more than one person.  Soon sex toy manufacturers were sending Casey free samples for demonstration.  Some were even considering sponsorship.

            Then InnerU found Casey’s page and reached out.  Apparently her extra large breasts package had turned out quite popular and had actually been nicknamed the "Casey special."  InnerU saw how good she was at demonstrating sex toys and wanted her to come help demonstrate some of the transformation packages they had to offer.  U2 parties had become a big thing, with InnerU clients demonstrating their changes live to interested audiences.  InnerU offered Casey the host role for one of their show circuits.

            It was a big decision, both for Caleb and Kristi.  If Caleb took the job, he'd be Casey nearly full time.  Effectively, this would push Kristi into Karl full time as well.  The couple had tired the other pairings, going shopping with Casey and Kristi or watching a game as Caleb and Karl.  They even experimented sexually that way, but nothing ever felt as right as Caleb/Kristi or Casey/Karl.

            It was while the couple was waffling that InnerU dropped another bombshell.  They'd finally worked the bugs out of their InnerHerm product, and if Casey took the job with them she and Karl would get the treatment for free.  As much as the thought horrified Caleb, Casey had been thinking a lot about what it would be like to have her belly heavily swollen with child.  She knew Karl wanted them, lots of them, but only if Casey was the one to carry them.  And if Casey did get pregnant, it would lock her in for the whole nine months.  Switching back to Caleb would threaten the baby and therefore that option would be disabled for the length of the pregnancy.

            After several long discussions with her partner and even more painful injections later, here Casey was.  Ready to do something that Caleb never would.

            "Have I said how beautiful you look?" Karl said, leaning down to kiss his wife on the top of her head.  Even after a year together, Casey couldn't get enough of his body.  The trails the muscles carved in his skin, like canyons carved by winding rivers.  The smooth shininess of his bald head.  The way he could make her squeal in pleasure like no-one else.

            But now her lover was sporting another new addition.  Casey reached out and stroked the positively massive penis hanging from Karl's crotch.  Casey was a slut, body and soul, but the size of it was enough to make even her take a step back and marvel.  Without her own modifications, such a monster dick would have ripped Casey in half.

            Reaching down with her other hand, Casey felt her own new addition.  The gaping cavern between her thighs, the lips pink and constantly dripping with lubrication.  Casey wasn't sure if the latter was a feature or bug, either way she was forced to wear period pads or mini diapers while clothed to prevent awkward wet spots.

            Casey still had her dick, but it had retracted back into her body.  Only the tip was visible as the bright pink of her clit.  Casey's balls had sucked inside her vagina, tucked neatly out of the way in a pocket.  When she shifted back to Caleb, her dick would extend and balls pop out to hide the slit of her vagina.  Not that Casey would be experiencing that change much.

            "I think you're really brave to do this."  Karl said, kissing the top of Casey's head again.  "Not only having them turn on your fertility, but supercharging it.  One good night of lovemaking and you'll be carrying several of my brats by morning."

            "It's what you wanted, isn't it?"

            "It is, but I don't want to pull you into something uncomfortable."

            Casey chuckled.  "I seem to remember having a similar conversation a year and a half ago, only in reverse.  Look how that turned out."

            "I enjoy looking at how you turned out, every damn day."  Karl reach down and picked up his petite wife, cradling her to his muscular chest.  "And tonight, I'm going to enjoy making you my baby mama."

            "A Valentine's day we'll never forget."

            Karl grinned, "Pet, I'm going to fuck you so long and hard our unborn grandchildren will remember this day."

            Laughing, the pair headed toward the bedroom and all the future things it would bring.
