my little 18 year old sister has enjoyed sex for some years and was talked into drinking piss and enjoyed it one night some years back some guys asked her if they could give her a piss enema she said ok as i always gave her an enema before i took her to parties to get fucked we went into the bathroom where she knelt down and let them start pissing in her ass watching them do it one after another and watching her belly swell was fantastic after 15 of them she said the pain was too much and she squirted it all out she does this regularly and over time has managed to take more and more
