I was dating this women and things were going great sexually. She then suggests we have get a little kinky and have a threesome. I was into it until she mentions she wants the first time to be with her, me and another guy. I was hesitant but when she said the next time could be her, me and another woman I agreed to go through with it. We found another guy to join us and there were the 3 of us naked. The 2 of us guys began to rub and touch her. The guy was very aggressive and even though we discussed that he wasn't to vaginally penetrate my girlfriend with his penis he did. I told him to pull out and he did but I got a bit of a pissed off look from my girlfriend. The guy then begins to suck me off. I wasn't expecting him to and he quickly stopped. He then puts his cock in front of my face and my girlfriend asks what I am waiting for. I begin to suck him off and pulls away after a minute and starts sucking me again. This time he sucks me until I am cumming in his mouth. My girlfriend tells me since I had just cum that he will need to do her. He quickly gets his cock into her and begins fucking her. There she is moaning and screaming with ecstasy as he is fucking her. They finish and the guy gets dressed quickly and tells me that is how a real man does it and winks at me as he leaves.
The next day my girlfriend tells me it grosses her out how I was turned on by getting my dick sucked by him. I told her I wasn't but she brought up me cumming in his mouth. She told me that wasn't important and what she really liked was the size of his dick and how well he used it. She said I was small and clumsy and gay for cumming in his mouth. She tells me we are through. I find out later that she told everyone that I came in another guys mouth and really enjoyed it. Everyone thought I was gay now but I did get approached by a couple of her girlfriends who offered to turn me straight. I wasn't gay but also not stupid and took advantage of her friends offer.
