I went some months ago to what I thought was a dogging site. I'm married but things at home meant there isn't any sex going on, so I thought why not. There seemed to be a few guys ambling about but no sign of women. I came across a guy completely naked who beckoned me over. I dropped my shorts, the guy fell to his knees and began sucking me off I thought who cares and shot my lot into his mouth, he was fine with this. On future visits similar situations occurred until I came across a guy who wanted me to suck him, he had a big and hairy cock and I thought why not give it a try. I told him not to cum in my mouth and he obliged. Having met several more times I decided to let him cum in my mouth, which I enjoyed. He now likes to rub his cock all over my face and slap his cock on it. Recently he decided I should be spanked for being a cocksucker, which I now am and tells me to get on my knees to suck his cock and made me swallow his cum. He has made me pull my pants open and wanked into them, then made me eat it. Yesterday he face fucked me and says he is going to bring his mates and let them do it to me. He has started to call me names and says I'm now his bitch. I seem unable to say no to his demands.
