"What about this one?" Mary asked, holding up a vial that read "Scaled".
"Mmm, only one way to find out." Danny said, smiling coyly. Mary was hesitant to take the vial. But once Sara emerged from the bathroom looking quite flushed, and smelling of sex, Mary was convinced. She took the vial, and drank the entire thing in one gulp.
A rush of cold passed through her body. Her skin cracked on her arms and legs. From the cracks, each section became hard and shiny. The pigment went from skin colored, to pink, to a blood red. Then the cracks started to appear elsewhere, on Mary's back, her breasts and her balls. As the transformation reached her more sensitive areas, she released a soft moan.
Feeling her nipples split open, and transform into hard scales was incredible. And then the taught skin on her scrotum moving and hardening, that was enough to make her hard. Her clit was poking out of her lips, and it was about the size of a grape. And getting bigger. Instead of a happy trail of hair, Mary now had one made of scales. It was almost as if all her pubic hair had been replaced by scales.
"Neat." she said, reach down to touch one of the scales on her thighs. It was cold to the touch, but she could still feel her finger pressed up against it. The touch sent all sorts of intense feelings through her body. She moved her hand from her thighs to the underside of her balls. From there, her fingers dipped into her vagina, which was surrounded by new scales.
As she started finger herself, Mary's other hand ventured up to massage her nipple scales. It didn't take much longer for her to come. Her scales became slick with pussy juice, and her clit throbbed as Mary's body was shaken by an intense orgasm.
Danny and Sara both had trouble containing their own erections. Danny's pants tented in front of him, while Sara's cock was all but plastered to her torso it was so erect.
Mary's transformation subsided, the last of the scales forming, and she looked up from her body. The sight of the erect phalluses in front of her were enough to bring her to an erection of her own. Her clit continued to bulge out of her scaled lips, to the point where it didn't look much like a clit anymore.
