Jay decided to go with a barely-legal slut. That would be a great punishment for Sean and an even better "happy ending" to Jay's day.
Looking through the options once already, Jay knew where to look. There were presets off to the side of Sean's image on the screen. "Let's see... You'll love my cock for sure!" Jay mocked the unconscious and inconsiderate roommate, "And it will be hilarious when you get back."
Jay entered the command simply. Sean would immediately change. It would last indefinitely, only Sean would not realize the change, and he would act the part while changed. Sean would disappear for a while nd in his place would be - "Now what's a sexy name?" Jay thought out loud... "Sandy," Jay typed.
He hit enter.
On the floor, Sean frowned in his stupor. He mumbled something and twitched his limbs as they became slim. His ass began to inflate and his hips widened. Jy could tell that a few years had been chopped off his age, but that happened too - as breasts budded and ballooned on the chest of the big-dicked dude. In fact, that dick wasn't going down at all. It was Jay's turn to frown. Sean lost inches of height and pounds of mass. His stubble receded, body hair disappeared, and his hair grew to shoulder length. Then it became badly bleached with dark roots. Sean - now Sandy, fluttered his eyes as the eylashes lengthened and his face completely changed shape. Pouty lips crested under a button nose. But Jay still frowned. He considered the massive rod still jutting up and twitching as Sandy writhed gently on the floor. He thought it looked kinda hot, now. But no matter - it was simply the last change. Jay got up and watched it recede into the crotch of the sexy kitten lying on the floor, leaving a perfect mound in its place.
