A female friend and I have been a bit open with each other sexually on a conversational level. It's not that we have a thing for each other, at least, not yet. I'm still debating on how I feel about her. Anyway, we went off to see a movie one day. Not too many others were in the theater. I end up popping a random boner which just wouldn't go away. Eventually, she noticed me covering up and took matters into her own hands.

At first, I protested when she reached for my crotch. However, I couldn't help but let her continue as she rubbed it firmly. I figured she would want the same as I saw her other hand on her own, but she knocked my hand away. It was nice and pleasant for a while. When I nudged her to stop as I was getting close, she only rubbed harder. It was a tad painful the way she was going, but I couldn't stop myself from shooting off. I grabbed the armrests tightly I soak my pants in cum. She resumed rubbing herself, but I couldn't tell if she truly finished or not.

Leaving the moving theater, I practically had to stay right behind her to avoid being caught with such an embarrassing stain. All she could do was laugh her ass off as she tried to step away from me.
