Locked in this position all I could see was theface and eyes of Mars. As the festival progressed guests would come up toread the plaque, sometimes gig...le or laugh, and then press the activationbutton. This would cause my entrapped partner to become erect and startmassaging my vagina. I would respond by urgently moving back and forwardson his penis until we both came to orgasm. I felt so humiliated but mybody was on heat and seemed to need the sexual release. There was nothingI could do to. I would usually think of this hot girl I knew, I would think about her nice tits, and her perfect shaved pussy, but since I wasn’t just jacking off, and since I was fucking my ass I had to think of something a little more gay. I thought of my brother. He is an ex-marine, and a really muscular, sexy man. I could only imagine how big his cock was, and how nice it must be to be able to suck and fuck it. I could only imagine because he was the last person in the world that would do anything. We managed to find a conservatory in a quiet part of the hotel where the party was taking place.Once we got there she told me to sit on one of the seats.She proceeded to unzip my trousers and pulled my cock from my pants."Wow" She gasped."Your cock is much bigger than my husbands".At this she took my cock in her hand and proceeded to slowly wank it before taking her tongue and licking the tip.This was very sensual and turned me on immensely.She began to suck down on my cock and managed to take. We had had sex in the car in semipublic places before - the chance of discovery added to the thrill, and being naughty also added to my enjoyment - so I knew what he had in mind. I thought I knew that is.As soon as he stopped I unbuckled my seatbelt and after we looked to make sure we were in the clear I sat there for a moment. I wasn't sure what he wanted exactly. He surprised me be suddenly reaching over and grabbing me, pulling me his way.I let out a small sound because I hadn't expected.
