Janine twirled the wand thoughtfully in her hands, looking at the two in front of her. "Ah" she said after a moment. "I know." She pointed the wand at Rick, and smiled when he yelled in surprise. Slowly standing, Jim helping him to his feet, he stared down at himself in horror.
"What the hell have you done?" he screamed, looking back at the centauress-stallion. Hanging between his legs to below his knees was a huge cows udder. It was attached up as far as his breastbone, and slung back well between his legs, apparently eliminating his genitals in the process. It pressed firmly against those legs, compressed into a space too small for it. It was obviously intended for a four-legged animal and wasn't hanging correctly with Rick in an upright position.
He reached down with a trembling hand and felt the upper curves of his udder. It stuck out nearly a foot around the level of his bellybutton, which was now covered by it. The four large nipples dangled from the front of the thing around his thighs, and when he tried to walk forward his legs pushed the udder back and forth making it swing and tug him off balance. The part of it between his legs rubbed against them, and the sensations were arousing. His new nipples stiffened and grew larger and he moaned.
Janine smiled. Jim took a step forwards and she looked at him threateningly. "It's not your turn yet. He still needs work." Looking back at Rick, she waved the wand again. His hands shot to his ears as they turned into those of a horse, sticking well above his head. The ears moved around, and he was worried to discover that he didn't seem to have any control over them. They pointed themselves to any sound automatically.
The centauress thought for a moment more, and then waved the wand a third time. A long monkeylike tail shot from Rick's spine, covered in tiger-striped fur but with the last eight inches or so bare and shaped exactly like a flaccid human penis. She stepped forward and reached down, grabbing the tail while Rick shouted. Squeezing the end, she let go and watched as it stiffened, becoming a fully erect penis nearly a foot long.
"That should do it" she smiled. Rick was nearly in tears for real by now. He reached down and felt his udder again. It was very heavy, and seemed to be getting slowly heavier. He had a good idea why.
Jim was staring in disbelief, but took a step back when she turned her attention to him. Suddenly turning he made a run for it, but nearly got whiplash when he slammed to a halt twenty feet away completely against his will. Looking down his eyes went wide, and he frantically felt his body.
Even in his state of shock Rick stared at his friend. From the waist down his body had turned into a tree-trunk, his legs merging together without a trace of a human shape left, and he was firmly rooted in place in the middle of the farmyard. Janine grinned at him and slowly approached, stopping a few feet away as he struggled futilely, wrenching his upper body from side to side in an attempt to dislodge himself from the earth. He didn't move an inch.
"Now, now", she said mockingly, "No running away." She walked around him inspecting him carefully, her hooves thumping slowly on the ground, and stopped at his front. "I think we can improve on this." She waved the wand again, and Jim's torso changed. It became more shapely and feminine, his arms and hands slimming down as well. Six large breasts grew in pairs down his front, the lowest pair hanging from his narrow waist over the upper part of his bark-covered lower body. As he struggled all six of his breasts flopped around, and he winced in pain.
"Better, but not finished", she said thoughtfully. Another wave of the wand, and a long prehensile tail similar to Rick's one grew out of the back of Jim's trunk, this one ending in a tubular structure that was obviously based on a vagina. His arms became covered in a bark-textured skin and leaves sprouted from his joints. He suddenly found that if he relaxed his arms all by themselves raised up until they were held above his head like branches. He could use them pretty much normally, but whenever he took his attention off them they went back into this new rest position.
Janine nodded in satisfaction. "That should do it. For the moment at least. OK, boys, see you later." She waved the wand a final time and the two transformed lads found themselves in Jim's back yard. Jim was planted in the middle of it in a nicely laid out flowerbed, and Rick was standing next to him.
The two looked at each other, then Rick staggered over to a nearby garden seat with his udder shuddering and flopping between his legs. "Fuck, this thing is heavy", he moaned, reaching down and massaging it. Grabbing a nipple in each hand he heaved the thing on top of his legs, and was startled and upset when a thin jet of milk shot from each nipple.
"You think you've got problems!", Jim yelled, his arm/branches quivering and his breasts shaking with the force of his voice. "I'm stuck in the middle of the lawn! What the hell are we going to do?" He pointed at Rick's udder with one hand, lowering it from it's skyward position to do so, and went on "You're going to have to get milked, and then you're going to have to figure out how to get the wand back and change us back into our normal selves." He didn't notice as his arm rose back into the upward pointing 'branch' default position as he took his attention off it, although Rick did.
"Me?" he asked. "How am I going to get anywhere looking like this?" His ears flattened themselves against his head all by themselves.
"It's not like I'M going anywhere, is it?" Jim asked with heavy sarcasm. Rick shrugged, and stood up. Walking slowly over to his friend with his udder wobbling around, he inspected him carefully. It was obvious that Jim was more than half plant, and his roots were firmly buried in the lawn. He wasn't going anywhere without the assistance of a shovel and a wheelbarrow, at least. Standing next to Jim, neither of them noticed their respective tails moving independently, until suddenly Rick's penis-tail slipped it's end into Jim's vagina-tail.
Both gasped at the sensations, and Rick stepped back. "Stop that!" he yelled.
"Me? I didn't do anything. You stop it!" Jim shouted back, then groaned in pleasure as his tail clamped down on Rick's. Rick dropped to his knees from the sensations sweeping through him then yelped in pain as he landed partly on his huge udder. Rolling over a little, he ended up on his back. The sensations increased for both mutated young men as their tails got more involved, and Rick found himself tugging his nipples as Jim massaged all his breasts.
The tail sex lasted for ten or fifteen minutes, until both orgasmed with a moan. Rick had disgorged several gallons of milk, and Jim was slumped over his immovable lower body, his arm/branches still pointing upwards but quivering a little. Eventually Rick struggled to his feet, reached around and grabbed his tail in one hand and Jim's in the other, and forcibly pulled them apart with a sucking sound.
