I had paid for my gas and then the feeling of needing a bowel movement. So, I parked my car on the side of the gas station next to the men's bathroom entrance and proceeded inside and sat down on a commode and had a normal bowel movement. As I was flushing the commode, someone entered the stall to the left of me, previously I had noticed a hole in the stall wall above the toilet paper roll. Very quickly the head of a cut penis appeared poking through that hole in the stall. As kind of a joke, I touched the underside of the penis head and gave it a few gentle strokes with my index finger. To my surprise the penis began to grow and as I watched it grow it seemed to be fully erect within a minute or so with a full six inches standing at attention through the hole.
I thought to myself what do I do now. I am not gay nor bi(I am married for 23 years with two sons)but, I know the feeling of needing to get off. Which this guy clearly needed to. With kindness and curiosity in mind I began jacking this guy off. First with gentle, fond strokes and then with increasing firm grips. I could tell this guy had his pelvic bone pressed tightly up against the wall on the other side of the stall with both hands grabbing the top of the wall, fingers turning white from the grip on the wall. He ejaculated onto the bathroom floor from my firm grip on his cock within four minutes and vocally let out a moan of pleasured relief. I watched his cock shrivel up to normal size and then quickly exited the bathroom. Not a word between us was spoken. The only sound made was me jerking off his cock and his moan of gratification.
