Pretty simple story, to be honest. Went out a few weeks ago and then were walking back from the bar to Dalston Kingsland station. My male friend and I went behind the railways arches to piss. We were walking to the station with our female friend and she needed the loo too but didn't want to go in public, so she just waited for us.

But like 50 metres further down the back of the railway arches she said that she was going to do it, but that we'd have to stand lookout for her. So we gallantly stood look out for her while she peed just back against the wall.

I've never found that sort of thing hot but seeing her pull her knickers down and then seeing the piss trickle down that pavement (it was a big ol' piss) made me incredibly horny. There was a little bit of steam cos it was chilly and almost 2am, and i could smell the piss. The whole thing lasted about a minute but I've thought about it so much since. And I can't help it but I really want her to piss on me. I would honestly just drink her piss if i got the chance. It's a new interest and not sure how to progress it...
