PART 1: I went for a drive near my local river and saw five guys standing around so I stopped nearby. I was in the mood so I stripped off in front of them and changed into my slinky dress. One of them was on me straight away, and quickly had his cock in me. His mates came over to watch. They decided they were all going to fuck me, and started arguing about who was going to use me next. I wasn't happy about fucking all of them, but they made me bend over so they could enter me from behind, one by one. It also made it easier for them to fuck my arse, which a couple of them did. Two other guys passing by stopped and joined in the queue to fuck me as well. When they had all finished using me, both my holes were filled with cum.
