How many of you have been part of this activity?

I've been part of it a few, just a few, times, but only to contribute my own piss. I've thought about getting into the tin bath when a guy gets out but haven't had the guts to do so - I suppose not wanting other guys to know how 'dirty-minded' I was(!), but wish I'd done it even just the once, even if I'd had to get sloshed first. Naturally I've asked to be pissed on in my own bath, but who hasn't? I love to watch the pissed-on guy's ecstatic face as he's soaked, usually opening his mouth. Great stuff!
