Dustin looks down at the vials, he picks two up. He is so horney but he is aching for more. One vial has the word evil written on it. The other pure muscle. Dustin's cock throbbed as he thought of both of them, he needed more, so much more.
He growled, pure pleasure inside him, oh god, oh god. Thinking about tasting one of the vials made him want to jack of. He couldn't stop the growls coming from his mouth, the beast vial making him more animalistic than ever.
His teeth were so sharp he knew he could break brick them no problem. He could probably break metal with his hands alone.
One vial was pure black, the evil one. The other is a glowing green. Dustin's mind was already twisted but imaging himself with no moral's, to be completely evil gave himself a hard on yet so did the muscle one.
He'd be even bigger, more muscler, more veiny, more powerful.
Which one?
