As the machine hums to life a powerful, magical glow infuses Hannah and Faith.
Hanna felt her lover melt into her, an intense surge, a lingering warmth, the sensation of a tremendous constant, body-long caress, and then the delicate, powerful sense of comapnionship... the knowledge that she'd never be alone again. No sooner had this wonderful peacefulness filled her than the other changes began coming in, new limbs, new sensations, familiar feelings from alien places.
Faith felt a similar rush, an overwhelming surge of sensation, pleasure, warmth and power, only once the initial wave crested she found a strange sensation... feeling, but without control, warmth, but almost weightlesseness...
When the chamber doors hissed open, Hanna and Faith all but danced out. The two see their new, permanent form in the nearby full-length mirror.
For the most part, they had inherited Hannah's body, including her full height. On her chest were three rows of breasts, Her originals, Faith's slightly smaller set, and the small additional set she had on the bottom. Alongside Faith's breasts were arms, with shoulders just behind and beneath Hannah's. They had four legs now, both their originals with Hanna's in front and Faith's, knees facing backward, behind them, giving them an almost spider-like gait. Their hips had been enlarged with barrowed mass, exaggering Hannah's hourglass curves.
In between Hannah's front legs was Faith's face. Her bright pink hair was gone, save for her eyebrows and eyelashes, her forhead vanishing just below Hannah's navel, Hannah's thighs right by her cheeks. But Faith's face wasn't entirely the same. Even in the mirror the two noticed an odd glistening to her lips, and when Faith ran her tongue over them, they filled with a powerful, familiarly pleasurable sensation. Faith's mouth had become their shared pussy, her lips sensitive as her former labia, her tongue a gigantic clitoris, and the inside of her mouth filled with wet and needy vagina tissue.
Brief exploration revealed that Faith could still talk, but doing so was intensely arousing. She could bring the pair to orgasm by playing with her tongue. Hannah held control over the majority of their body, but Faith, on top of her extraordinarily erogenous face, still controlled her original set of arms, beneath Hannah's.
As the two explored their new, shared form, Lysette approached them. She smiled at the conjoined lovers, Julie's eyes beneath her clavicle widening with... excitement? lust? surprise?
"You look amazing! I'm so happy for you!" Lysette cheered, running a hand over her own four rows of impressive tits. "Maybe you'd like to.... explore together?" she purred, licking her new, full lips with the offer.
