Jean wasted no time kneeling down and starting work on Rebecka's left leg. Working out from the support rod Jean ran her hands all up and down the leg, stealing squeezes at Rebecka's butt, while kissing and licking the flesh away transforming it into smooth plastic. Once most of the leg was transformed she removed the sandal and worked on the foot, making sure to get at every last piece of flesh. She repeated this process with the right leg, this time starting from the foot and working up. Occasionally Jean would stop and rub herself up against her girlfriend's new plastic limbs, but would manage to bring herself back to the task at hand before becoming too caught up in her distraction. With her girlfriend's legs done Jean decided to finish the whole lower half, and so started work on the pelvis up to the hips, this time taking breaks to go over Rebecka's crotch again. When the front half was finished Jean moved to the back, before she started the change though she poked her head around so Rebecka could see it in the mirror and said "I know you might be angry with me for this, so I'm going to start kissing your ass now to make it up to you." After giving the fleshy cheeks one last squeeze Jean started doing just that, giving Rebecka rock-hard buns. Continuing on the back Jean kissed and licked, following the line of Rebecka's spine first then branching out. She placed lines of kisses down each of Rebecka's sides creating pools of hard plastic within the soft flesh before licking the unaffected areas. While Jean's mouth was busy transforming her hands were busy alternating between playing with Rebecka's nipples and rubbing anywhere that had already become plastic. When Rebecka's entire back had been transformed Jean gave her another embrace from behind, the moving girl reveling in the cool, smooth feeling of her girlfriend's plastic parts. Jean almost let herself get distracted from her goal in that position, but her hands feeling the flesh on Rebecka's stomach reminded her that there was still work to be done.
Lips met stomach and soon Rebecka had a harder stomach than even the most aggressive fitness lover, along with an equally hard torso just up to under her breasts. Those Jean decided to leave as a treat for near the end, first transforming Rebecka's right shoulder arm and hand, taking each finger fully into her mouth and running her tongue all over them. the left shoulder followed, as well as the hand, and most of the arm. Jean left the elbow untouched though, as she'd had to move the arm out of the way before transforming the torso, and having a something blocking the way would be no fun while changing the breasts. With the arm done Jean embraced Rebecka from the front and started kissing at her neck, sometimes biting a bit before getting her lips or tongue involved. By this point all that was left of Rebecka's flesh was her face, elbow and chest, so Jean decided it was time to lighten the load on her girlfriend's chest. Rebecka's nipples were still fully erect and Jean slowly worked her way towards them, sometimes planting long slow kisses, sometimes lightly brushing her lips against the soft flesh below, sometimes licking. No matter the method flesh would quickly become plastic, and before long the large fleshy mounds on Rebecka's chest were just two round orbs with fleshy protrusions, which Jean grabbed with her fingers to play with. Jean then leaned in and kissed Rebecka's lips, then traced her lips down Rebecka's chin so that the plastic lips weren't an isolated patch. Jean delicately traced her lips over the rest of her girlfriend's face, taking special care around the eyes, which became green glass orbs embedded in the plastic sockets. With Rebecka's face done Jean allowed herself to kiss away Rebecka's aureola, making it the same colour and smoothness as the rest of the breast, before finally taking Rebecka's nipples between her lips. The result was rounded plastic breasts with a realistic but still too-perfect plastic nipple capping off each, just the right size to be seen though a tight fitting swimsuit but not enough to be obscene. Jean then swung Rebecka's mostly plastic left arm back into place before hardening up the elbow with her tongue. Jean wasn't ready to kiss at Rebecka's scalp through her hair , so she brought out a cream the store owner had given her and used that to finish the transformation. "I can already hear you wondering why I didn't just use this cream on the rest of you, but I think you already know the answer to that: It wouldn't have been as fun! Anyway I've finished you off so it's time for you to finish me off!" Jean gave her plastic girlfriend a wicked grin before reaching down, decoupling the mannequin from the support, and carrying her off to bed.
