Big Cock Fun - Try to pull your shorts up.
From Create Your Own Story
Trying not to weird the guy out, you pull your gym shorts up over your butt. By doing so, you accidentally loosen the waistband of your shorts, so that now, not even your butt can keep them up and after a few steps they drop down to your ankles, tripping you up.
You stumble forwards head-first, but before you can fall far, you feel a strong grip around your waist and steady feet behind yours, securing you midair. Your savior pulls you back into a standing position and holds you with his hands on your hips close to him.
"You alright, man?" He asks with a broad smile on his face. You expect him to step away from you any moment, but he doesn't seem to be in a hurry.
"Yeah, thanks to you, I guess. You saved my ass, man." It might have been your imagination, but you think you felt a soft twitch, when you said "my ass". You try to look at the man behind you and gently rub against his crotch with your butt. This time you're quite sure, his cock reacted.
"Just let me get my shorts ..." You begin, but he interrupts and begins to bend down.
"Why don't you let me get those for you?"
You ...?
