Go for the third door, in-between the two occupied ones.

You go into the stall between the two occupied ones. There is a TV with some porn already playing on it. There is a buxom blonde woman on her knees getting fucked from behind, while giving a blowjob to a guy in front. Usually when you watched porn as a man you would envision yourself as being one of the guys fucking the girl, but you can't seem to help picturing yourself this time as the woman getting fucked.

You pull your pants off and take a seat on the ragged bench, and start teasing your pussy softly with your hand. You're still not sure about what you are going to do, but after tasting that strangers cum, you have an irresistible urge to eat more semen, and you don't care where you get it from.

You pull off your shirt, you are now completely nude in this seedy adult theater. Your red hair, and fair skin glow softly in the neon light, and you find yourself admiring your body yet again.

You are reminded of your mission as you hear some noises from the adjacent stalls. There is some porn videos being played in each of them, but on top of that you're sure you hear some shuffling sounds, and a man breathing heavily. Taking a peak in each of the holes on either side of you, there is indeed a man in each of them, masturbating to the videos.

The man on the right looks very young and handsome enough. Probably a college kid killing some time between classes. His jeans are at his feet, and he is wearing a button down shirt. He is slowly stroking his exposed member, and it looks about 8 inches in length.

On the left, is an older man, perhaps about 35 or 40. His pants are up and he is stroking his 6 inch penis through his fly. He's much more muscular than the college guy.
