Jenny watched the horsegirl making out with Chloe between her thighs, her eyes half-lidded with the sensation of licking. But there was still the matter of what to do with the other horsegirl. Tapping her upper abdomen, Chloe started to unmerge from her body, actual mouth and lips meeting the first horsegirl's as Jenny stepped back, unmerging more and more of Chloe until she was kneeling, locked in a heated makeout session with the horsegirl.
Jenny left the two of them to it, approaching the other horsegirl. "I want to do something special with you," she cooed, reaching a hand up to brush across the horsegirl's cheek, capturing it as Jenny leaned in for a kiss, sealing the horsegirl's fate. As Jenny drew back, the girl's upper body began to merge with her lower, at the same time her skin was turning a dark, ashen grey and becoming thinner. She opened her mouth as her head tilted back, more and more as Jenny transformed her into a pair of waist-high, high-dernier opaque grey stockings. The cloth oval in the middle, what had once been the horsegirl's vulva, was especially soft to the touch. Jenny knew that the horsegirl could feel the pleasure of her fingers rubbing the material back and forth.
"Don't worry, I'm not done yet," Jenny reassured the horsegirl-turn-stockings, stretching her around one foot's toes. She was especially careful to line the seams up across her toes. As Jenny slid the stockings on and stretched them up to her waist, making sure every bit of her legs were covered with the thick nylon in a uniform spread. It was only a few seconds later that the stockings began to permanently merge with Jenny's body. She could feel the soft, silken girl-material joining to her body. She'd made the horsegirl a half-size too small for her, which only increased the contact that she was able to make, perfectly lining the soft cloth oval that had been the horsegirl's vulva with her own, and an orgasmic shudder passed through Jenny's body when her labia were joined with the stockings, and from the waist down, Jenny's thighs, calves and feet had become the smooth and soft material of nylon stockings in a deep ash-grey color.
Immediately, Jenny's fingers went to the bare space between her thighs and started rubbing the cloth oval, orgasming almost instantly. It was a full-body experience, more of a mental explosion of endorphines than any physical response. She realized she could do this indefinitely, and then flexed her toes, stretching them slightly within the living nylon stretched across them, and then stood up. She padded around the room a few steps, coming over to pet Chloe and the horsegirl's heads. She couldn't stop fingering herself, even though there wasn't anything to finger, really, just that expanse of extra-sensitive oval.
"Oh, this is perfect. You're perfect," she praised, rubbing her stockings on the thigh affectionately.
Returning to her laptop, Jenny summoned...
