Mark couldn’t help but stand back from the mirror and pull his arms up into the classic double bicep pose, he flexed and watched as his increasing hairy arms popped into lovely rounded peaks of muscle. He stepped back again and pulled his arms down and crunched up his chest into a most muscular, gasping in awe at the hairy muscle he now had. It certainly looked like he worked out, he kept posing letting each muscle flex and harden feeling the blood pump into his arms, his chest, his legs and his cock which hardened as he got off on his new body.
Mark felt magnificent. He’d always wanted a body like this, he’d always been jealous of the jocks at High school, always wanted to build muscle and unable to. In his dreams he’d wanted to be Mr Olympia and strut the stage showing off his powerful muscled body to thousands of fans.
Suddenly he remembered the built in wardrobe had a full length mirror and he left the bathroom his hard cock bouncing in front of him as he walked, no swaggered through the bedroom flexing his thicker legs and holding his chest and arms flexed in the ‘relaxed’ pose bodybuilder had to do. He swung open the wardrobe door and stared at himself and smiled. He was hairy, hung and built, everything he wanted.
Mark posed. Every one he knew or had seen he tried. He flexed and grunted and stretched his body as if to some unheard posing music. His dick stayed hard and he didn’t touch it, instead focusing on his routine. All the time he posed he could feel himself growing, his muscles inflating, the hair growing thicker and turning black; the changes only drove him harder. He moved from looking like a teen bodybuilder into a serious male weightlifter, his belly did not shrink, if anything the ball grew, but it was solid and covered in hair so thick he could not see his now tan coloured skin.
Time stopped meaning anything for Mark; hours must have past as he posed, grew, adapted his posing to the new mass, grew adapted… he worked himself into a sweat and then finally fell backwards onto the bed exhausted but happy, his still hard untouched cock pulsing like the rest of his muscles as he dropped into a deep sleep a wide grin on his bearded face.
