Byran slowly moved his right hand up & down his red, glistening cock. Finding it amazingly slick, his newly shaped dog hood was now secreting some kind of strange lubrication that was oozing from his organs flesh. The world seemed to stop around him as Byran explored himself, in all his years of jacking off nothing ever came close to the levels of euphoria that now washed over him. Byran's eyes rolled back in his head as stroked, his tongue lolling out of his mouth mindlessly jacking away. His family looked on as Byran began to show the dog in him, his arms & legs becoming covered in soft brown fur, feet & hands gloved in thick black fur. Gyrating wildly, he began to shake, feet becoming erect, toenails splitting as blood trickled to the floor, short blunt claws pushing forth as was his hands. Soft leathery skin showing across the balls of his feet, his calloused palms, his paws slowly developing.
Fur on his body becoming the thickest at his thighs, hips & ass, spine slithering out from above Byran's butt sliding in to existence. Byran suddenly found himself snapped back to reality for a few brief seconds, he tried to will himself to stop but by now it was far to late. He couldn't help himself, Byran found he had no control over his hands or legs. Balls tingling he began to foam at the mouth, his muzzle lurching forward with a sharp, C-R-A-C-K, black & furred just like the saddle across his bulging back. Chest barreling out, black ears sliding their way up Byran's head, fangs lengthening, saliva hanging from them. As Byran felt the pressure build in his scrotum he howled as the changes completed, human sperm exiting his new body.
Then as suddenly as it started it was finished, Byran felt control of his body return. As Byran held his cock in his paw he suddenly felt his balls tighten, without warning Byran felt the biggest orgasm of his young life. Thick Shepard cum shot out at leat three feet spaying the walls & his family, lasting for several minutes before slowing. Panting heavily with his new longer tongue Byran leaned back against the hallway, so much for his date tonight, he thought to himself, or was it? Deep in the after glow of both change & sex Byran grinned wickedly as a dark thought of his girlfriend's ass covered in fur made his flaccid penis go hard again.
