I needed a piss today, so I went in a public toilet next to the bus and train stations at Vauxhall, South London. There were two urinals, one occupied when I entered, and one that the guy in front of me went for. I needed a piss pretty badly but not bad enough to use a stall in a public toilet, so I waited for them to finish. I figured the guy who was already at the urinal was probably nearly done by now (how long does it take to pee? like 30 seconds?) so I wouldn't have to wait long.
So anyway I was waiting there, and to my surprise, the guy who walked in in front of me finished before the guy who was already there. I thought, "hmm, maybe he guy who was already there had only just started. He'll probably finish up soon." I started to pee, and I noticed out of the corner of my eye that he had started shaking it off. "Oh, okay, he's done now. He'll be gone in a sec."
But no, he was not gone. In fact, by the time I finished and started shaking it off, he was still there. Shaking it off. "Hah, maybe he's wanking!" I thought. "lol, yeah right, like anyone would jack it in a disgusting public toilet in a south London bus station. Strange that he's still shaking it though..." I slipped it back into my boxers, zipped up, and went to wash my hands.
Now, the mirrors above the sink were facing out into the urinal area. And it was a small public toilet - only 2 urinals and a stall, remember. I could see both urinals, from the side profile. I washed my hands, trying not to look. "Just keep looking straight ahead, son." But I couldn't help it -- he was there, pumping away, not a care in the world. He was wanking in a south London public toilet. In a urinal, at that - not even in a stall!
I carried on washing my hands, keeping my head down. But now I needed soap. I looked up, for the soap dispenser, but found another dispenser of thick, creamy ooze entirely. Still beating it, the guy was starting right at me!!! He was *looking at me*. WHILST WANKING. WTH MAN!!! WHO THE HELL DOES THAT?!?!?!
I got out of there pretty fast.
tl;dr - I went to a public toilet for a piss and the guy in the urinal next to me was wanking and using me for porn when my back was turned.
