Mark huffed as he got back to his hefty feet, dick still stiff hoisting up his fat gut. Just beneath it lie Ray who, once he realized his girlfriend-turned-boyfriend's load was beginning to seep around him quickly sprung up from the ground. Almost head butting Mark's cock head.
"Well hun," mark bellowed. "Was it everything you thought it be, having a big hefty man to please you." She made a show of padding his Italian car sized gut, sending little ripples across his girth.
"It's a start mark." He said. Mark's name catching in his throat as he was not used to his new name yet. "I think I've come to understand something though..."
Ray walked over to the case of vials and rooting through the drawers echoing glass clattering about.
"Oh?" Mark stated, scratching his underbelly as he took heavy shaking steps to his boyfriend. "What's that?"
"I think I've had this fantasy of mine a little wrong..." He took a number of vials in one hand and more in his other. His first hand reached up and while throwing his head back drank all the vials in it then set them back down. "I've always thought big thick guys were kinda hot..." He took the other hand and downed them too. "But it wasn't that I wanted to be with one, I wanted to BE one!"
Marks skin took on a leathery sheen and thick scales began to form across his body. His body of which began to bloat and bubble unevenly as thick layers of fat and muscle collided against each other quickly bulking up his average frame. Parts of his body swelled with firm muscle then washed over by soft fat.
6 pack abs formed only to be draped in a pot belly that then bulged into an 8 pack and finally a thick curtain of lard came to rest as an massive fat gut.
Legs bulged with firm hard muscle and quirkily inflated with cellulite flesh. His feet became claws and popped into fat sausage like toes.
His arms reached body builder promotions, crisp lines and bulging vains pulsed as he flexed them in admiration. As he grinned at his growing body his mouth jutted out, sharp teeth in a crocodile maw as his head changed shape. Just as his head finished a dangling flab of skin formed on his arms causing them to lose some definition but none of his build.
His ass tightened into a juicy bubble butt that Mark leaned around to get a better look at, catching his tail erupted out his spine and dropping to the floor with a heavy *THUNk!*
Hair sprouted from his back and head, growing in a black mohawk like Marks that ran from head to tip of tail, only Ray's was a few inches longer.
Mark paused to wonder why that was when Ray lifted his arms again to flex revealing the thick strands of hair that bloomed into black bushes his armpits!
"Now for the pièce de résistance!" Ray boomed in a deep base voice that overshadowed Mark's.
Ray reached for his gut grabbing thick folds in his pudgy fingers and lifted the shelf of scaly light green fat showing of his small human cock as it was swallowed in a Black Sea of pubic hair. Then like a rocket a red throbbing shaft of cock flesh shot out from the forest of knotted hair. It reached six feet long in just 5 seconds and three feet wide. It extended another foot when a scaly green sheath enveloped its base, parting some of the black hair between his legs. His balls equally hair also expanded, each the size of and exercise ball and pulsing with life.
He dropped his but and watched it fold over the sides of his gargantuan cock. Ray hand become an almost perfect copy of mark only more. A foot bigger in all directions, hairier, more masculine. Just more in every sense of the word!
"How do I look babe?" Ray boomed again, his voice so big Mark saw the glass of the windows vibrate slightly.
"Damn man! You got hot!" Mark stammered in response, looking slightly upwards at his boyfriend.
