Christina lunged, and before Alyssa could do anything, a bite had come and gone.
Alyssa touched the wounds on her shoulder, but the blood she wiped away revealed unbroken skin.
"Joe?" She asked, her voice shaking. "What--what happened?"
Christina was already reverting to human shape--without even the baggy clothes on, I could see that my roommate made a hot woman--I wished that her pussy would be shaven while she was in human form, and thousands of tiny golden curls disappeared.
Christina's voice answered before I could. "He's getting another pet. It's your turn, now." And with that, she began to rake her nails down across Alyssa's form.
It was obvious that Christina was being deliberately slow--the faintest red lines were left behind by her nails, and that minuscule pain was just enough to start the change.
It seemed to interact with the wish I had made minutes ago--rather than Christina's painful transformation, Alyssa seemed turned on. She touched the red marks, the scratches, like the burning echo of lover's kisses. She writhed, trying to push into the scratches, make them dig deeper to make the transformation more intense, but Christine knew better--the red marks never grew any deeper, and they quickly healed as the changes progressed. She moaned--yowled--and I realized that was another tiny difference my earlier wish had made. The faint wounds across her breasts made them swell like ripening fruit, and she gasped as her figure filled out and became more lush. Nipples sprouted below her two human tits, and budded, blossomed into full breasts themselves as her ears slowly drew to a peak.
"Sssstoooppp..." She said. But she didn't want to. It was obvious--her hand was drifting toward her pussy--that was where the hair started to spread from. It grew in slowly, and I could almost count the hairs sprouting--soft cat's fur, not pubic hair anymore.
Christina did stop for just a moment, just long enough for the changes to slow, stop, and just barely begin to revert--and then her own hand beat Aylssa's, and she slipped a single finger in between her legs, slick already. Alyssa yowled again, and the change accelerated.
I hadn't wished that Christina be bisexual, but apparently it was a freebie. Either that or she was just casting any "heterosexuality" to the side for a warped sexual payback. Or maybe since Chris had been a straight man, liking girls, that part had just never changed since I'd never asked it to change. Or maybe...
I was overthinking things.
Alyssa screeched madly as she clamped her hands onto Christina's shoulders, and her claws dug in sharply.
Christina yelped as the nails left deep, bleeding furrows, in her shoulder. Perhaps they would have been serious--her changes was rapid this time, fangs growing and shaggy golden fur spreading again--and then Christina reciprocated, and bit again. I knew it wouldn't change things--it wouldn't make the werecat a werewolf--but the added pain, mixed with the sensual pleasure, forced the transformation to a rapid conclusion--midnight fur enveloped Alyssa's face, and as her eyes stared in orgasmic rush, I saw the iris turn emerald, her pupils dilate into slits. In her gasping I saw her muzzle push out and her canines become needlepoints. Her feet snapped into digitigrade shape, and her tail lashed furiously.
Her yowl died down into a growl, and then into a purr, furry hips bucking softly still.
My cock was in my hand, and pumping madly.
With her face full of post-coital bliss, Alyssa eyed me over Christina's shoulder, whatever hate she had borne minutes ago erased, or at least temporarily forgotten. "Mrrrrrr...." She murmured. "All this for me, and nothing for him?" Her voice, still feminine despite her massive shape, was mocking, gently teasing. "We're horrible, horrible servants, Joe. How can we make it up to you?"
