Jeff scrolled through his options before deciding on partially becoming a deer. Or rather, as he blushed, becoming part doe, a female deer. Setting the changes so that they would occur over time, rather then all at once Jeff set the time limit for a week so that he could... Experience his changes.
Clicking the submit button Jeff sat back in his chair, only to fall onto the ground, naked in a field with several deer around him, ignoring him.
Standing up Jeff looked at himself, blushing becuase he was naked in the middle of what was basicly the woods with a bunch of animals. Rubbing his crotch Jeff wandered around the field for a little bit before rubbing his head in confusion, why wasn't anything changing?
Looking down at himself Jeff looked in confusion as something came up behind him. Turning around Jeff saw it was a buck, one who apparently wanted to mate.
Jeff's dick stood at attention as he smelled the arously coming from the buck, which was turning Jeff on despite the fact he was currently male. 'Wait a second... That's what changes! I'm starting to think like a doe on instinct!' Jeff thought, no wonder a buck was turning him on.
Letting his next instincts take over for a bit Jeff found himself bending down and presenting his ass to the buck, his dick still adjusted as the buck mounted Jeff, sticking it's large dick in his ass. Jeff's eyes bulged as he tried to hold in a cry from pain and pleasure as he started changing due to his current sex with the buck.
Slowly his dick, which was still aroused, shrunk, growing smaller by the second as his testicles retreated. As the buck rammed him harder and harder his dick got smaller and smaller, until it was little more then a nub on top of a slit that was starting to form in place of his dick. With a wet pop his penis slipped into place, becoming the clitoris of his new doe hood as the buck ejaculated within him, flooding his insides with cum as his stomach budged from the cumming being forced into his intestines.
The buck dismounted Jeff before leaving, leaving Jeff to quiver on the floor as cum dropped out of his ass, and his doe hood leaked of arously. He wanted to mate so bad because of his new insticts, but he held it in as he wandered towards a tree before sitting down at the base of it to examine his doe hood.
Sticking. A finger inside Jeff moaned before pulling out and standing up. It seemed his changes were brought about by having sex, which would happen until a certain point like he had set on the chronovac. But right now he wanted to let go... He wanted to mate.
