I gave one guy oral and fucked another guy in the ass in a roomful of people in a hotel ballroom at the Women Who Love Male On Male Action party at Frolicon 2013. Since I don't tend to be a quiet sex partner, the latter kind of got the attention of the whole room at climax-- it's very satisfying to finish up sex to a round of applause.
Yes. In an hotel, my girlfriend and me were sharing a room with her brother and her sister. During the night, my girlfriend and me made love and the others were sleeping in the same room.
I once had sex in the back of a movie theatre. My date had a short skirt on, half way through the film she removed her panties. She then slid across and placed herself on my lap, opened my flies, and started bouncing away! I came inside her within a few minutes!
Yes. Was at a camp with a few friends. I arrived late and they had already started drinking. When I got there they where all horny. The one girl started teasing me. Her boyfriends brother was there also. He started playing with another girl. We then decided to go to a room. We all got undressed and started playing with the girls. We then watched the other couple have sex. Once they finished she told her boyfriends brother to not tell a word of what is about to happen. He actually agreed and then we went at it. First we did missionary then she went on top. When I got close to finish I got her on her back again and unloaded on her chest. That was so intense and fun and best off all I was the only one sober.
