Doping

Frank was excited to try a new type of steroid his friend had told him about. He didn't know all the details, something about extreme muscle growth, but was happy his friend had managed to find some. It wasn't long before they were over together, Frank getting his first dose of the shot.

Frank didn't expect the soreness of the injection to grow from its spot, quickly traveling to the rest of his body. It felt almost like he had just worked out, quickly realizing that his muscles had started to pump up in the same fashion. He quickly removed his clothes, stepping back to look at his entire body growing before his very eyes.

Frank never thought he'd be this big. He leaned back on his bed, watching as muscles seemed to materialize right onto his body. He flexed, watching his skin ripple with veins popping out of his skin. He laughed, never thinking to have ever gotten to this size, muscles bulging all over. As he clenched his fists, he felt something strange, his muscles locking into place. He tried to move them but they were unresponsive, his arms and legs unable to budge.

He fell forward onto the bed, stretching his arms out to catch himself. In a moment he realized he was locked in position, kneeling on the bed on all fours, his ass sticking out behind him. He tried to move again, but couldn't. "Why can't I move?" He asked, panicked.

"You're a muscle freak now that can't control your muscles" His provider answered.

"You have to help me man" Frank said quickly.

"With pleasure"

His friend stepped closer pulling his pants down, revealing a long cock slick with precum. Frank felt a jolt of pleasure rush through him as it penetrated him, his body quickly flooded with chemicals sending shivers through his nerves. His body shook as he was quickly euphoric, his tight muscles heightening the arousal he felt coursing through his body. He felt himself pushing back against his friend, his body taking on a mind of its own responding to the thrusts.

"What the fuck!" Frank cried out. He felt the muscles on his back and ass flexing as he was filled, pressing the shaft forcefully against his prostate sending shocks through his mind. Frank could hardly think straight anymore, each moment a shock from his spot sending his thoughts spiraling. In a moment his mind was empty, his mouth gaping open drooling just like his dick, his body nothing more than a fuck toy.
