First time public human toilet

I wanted to go dogging on a well known resting-place at the highway. When I came this night, several cars were there, but no one was to be seen; all somehere in the woods... I walked down the path between the bushes and trees and heard moaning and other familiar noises from deeper in the woods. After a few meters I meet two naked boys and a girl on a planket, the girl had cum in her face. I said "hi, you need some help with your two friends?" she answered, that she would only wait, till the two could go a second round, and that she didn't want to share her cocks... One of the two boys got up, went a little by side and wanted to start to pee. I dont know why but i asked him "do you want to pee in my slutmouth`" he turned around "what???" I answered, that he understood right, if he wants, he could pee in my mouth. I took the bikini-top of (at dogging I usually wear chastity, heels,short skirt and a bikini-top), went on my knees in position 1 (kneeing with open legs, upright, hands with open palms upwards on the thighs) and opened my mouth wide and head a little backwards. He walked over to me and put his cock in my mouth and started pissing. I swallowed as fast as I could, but it still ran down over my cheaks and chin and breasts,... The second guy also got up, came to me and started pissing on my head, I now was compltely soaked in piss. And I loved this feeling, to be the human toilet for complete strangers!! I asked the girl, I she didnt need to pee and if she wanted the cum licked of her face? She pissed too in my mouth, not so much, but she tried... I went on on the way in the wood. I asked everybody, I met that day, if she or he wants to pee on me or in my mouth. It was soooo supergood!! Since that day, when I go dogging, people know me as piss-slut and demand to piss in my mouth. I love it!!
