Today I 19F was celebrating a family friend's high school graduation. We rented a gigantic house about 4000 sq. ft. The party started as all usually do, we made some food until people started arriving and helping with the food, etc. It was around 8pm when Austin (the graduate) asked where he could take a leak. I wasn't horny, (that horny) but I lead him into the closet and showed him my ass saying I can take it in my mouth or ass. It didn't take long before he was using my mouth as his personal toilet. A few hours later he came back with some friends asking if they could use the toilet again. I believe there was 2 guys with austin and 3 girls. I wasn't sure how the girls would be able to use me but I agreed. I led them to the closet, stripped down, and let them choose. Austin chose my mouth again and the other guys chose my ass. Having that much piss in my ass kinda felt like I had a water balloon in there. While on the other hand when austin and his 2 male friends left I was still wondering how the girls would use me. One of them ended up just siting on my face and I sucked it out of her while the other two flipped me against the walls o my ass was facing up and they used a funnel to funnel their piss into my ass hole. After the party they said they'll come by tomorrow and we can have a real kinky session. I'll post a part 2 tomorrow or the day after
