Lab.oratory is a gay club in the same building as the famous Berghain nightclub. It has a reputation for offering quite hardcore events, such as cruising in total darkness and fetish parties. One of these regular events is called “Yellow Facts – piss and fuck party”.   Now, I’m not interested in sex with other men – not least, I am too scared of picking up something nasty at a place like Lab.oratory. But I am a piss-slut. I love drinking piss, having piss enemas, being pissed on.   So far, I’d only enjoyed water sports in sessions with dommes, where the rules are clear. But what would it be like at a gay fetish club? I did my research, and found little information online outside the Lab.oratory’s impressively uninformative website, and some of what I did find turned out to be wrong (for example I had read somewhere that on arrival I would have a number written in marker pen on my shoulder – this was a source of anxiety, as explaining that at home would be rather difficult).
