"uhhh... I .... uhh" muttered Thomas, looking lost and very confused. Suddenly, he dropped to his knees, pulled down your speedo and began to suck on your tiny roid cock.
"Here we go" grinned Runt, watching intently as the boy's head bobbed back and forth.
"Ahhh yeah" i moaned with satisfaction. Suddenly a wave of ecstasy hit me as cum started to run out my cock like a faucet. I moaned louder as I heard Thomas gulp every mouth full.
Suddenly, he began to grow. His frame widened slowly, muscles inflating under his clothes. His chest thickend to giant round pecs, arms and shoulders becoming thicker and veiner by the second, needle marks appearing hear and there. His neck widened till it was thicker then his head. His already well developed legs grew meatier with muscle until they where thick as normal mans waist. His six pack abs began to distend and bulge out to form a roid gut, as his once perfect skin also became red and blotchy, across his cheeks. His hair began to recede, not as much as mine. Inside his pants, his cock shrank into a tiny roid dick. His shirt changed from a spiderman one, to a grey one with large white letters reading 'Roid Boi & Proud'. He also had his IQ lowered, and became illiterate as well as sex mad.
"Woah...' he said, pulling my dick out his mouth. He stood up and looked at his body in the mirror. He still had his handsome boyish face, but on top of a young roiders body. Thomas was now a young roid head that had been jucing up since the age of 15, and spent most evenings at the gym, lifting or sucking any cock he could find.
"Looking hot there bro" I said, slapping Thomas's ass with one of my big meaty hands. "Like the new look?"
"Yeah bra", he said, his voice now coming across more dumb then before. He flexed in the mirror, watching the veins pop up on his biceps.
"Yeah, ya look good as a roid boy" I said, getting up and pulling him closer to me. I leaned down and began to make out with him. Thomas happily obliged, feeling himself up as he grew hornier.
"What the hell is going on here?"
We looked up to see one of the gym employees. He was 26, 5"11, fair skin, dark hair, handsome with a sexy stubble beard. Well built, muscluar body, like a models, but more bulky. He was wearing his gym uniform, a blue polo shirt and dark blue shorts, with a name tag reading Derek on his chest. He had black studs in each ear lobe, and a tribal tattoo going down his left upper arm.
I paused as I thought of what to do with him.
