Jeff closed his eyes as a rather cold feeling washed over him, shivering for a moment as he leaned back in his chair. He knew the chronovac was already changing him, it was just a matter of time to see how much. Reaching down into his pants Jeff slid his hand into his underwear and started fondling his dick, knowing that he wasn't going to be keeping it for very long.
'Why do I even bother, might as well watch it all happen.' Jeff thought as he pulled his hand out of his pants and lifted his shirt off, exposing his bare chest as he removed his pants, followed by his boxers with a slight blush on his face.
Cradling his dick in his hands Jeff rubbed it idly as he shivered. The cold feeling washing over him again, seemingly focused on his groin. "Guess my male gender is going first." Jeff muttered sadly, he hoped that it wouldn't be until later he lost his maleness.
Looking down at his dick Jeff cradled it in his hands as it quivered, eliciting a slight moan from Jeff as his balls started their motion upwards into his body, his dick shrinking slowly as his scrotom tightened. Jeff continuing to rub his ballsack until his testes had moved into his body and his scrotum was little more then a dark line of sensitive flesh.
His dick shrunk even more as his urinal tract receded, leaving his fleshly rod very sensitive as Jeff moaned, rubbing it wildly as it shrunk. The skin of his former scrotum starting to spilt apart as a rather quiet rip came from just behind his dick, or rather now with his dick sticking out of it as it thinned and shrunk. Jeff grunted as his hips widened, a large cavity forming within him as a warm feeling spread throughout his body, his testes having become ovaries.
Fingering his next vagina Jeff moaned as his dick finally finished it's slow shrinkage, and with a little pop it settled into his vagina as his new clit.
With the pleasurable sensation of having lost his dick and gained a vagina, Jeff looked down at it and wondered just what would change next.
