Around two years ago my girlfriend (now wife) confessed to me her fantasy of a devil's threesome and watching me get down and dirty with another man. I wasn't sure how to feel at first, especially because she knows I'm straight, I'd never experimented with a man before nor had the urge. But, I suppose that added to the thrill for her, as she vividly expressed how turned on she was by just the thought.
Despite being clearly intimidated by the idea, I kept an open mind and decided that if it makes her happy, I'm happy. After some thought I agreed to indulge her. Having no interest in men myself, I gave her full choice in who the other guy would be. Immediately she picked her ex boyfriend from college who I'd heard about in the past.
So fast forward to the night of, the three of us naked in our room together, I'm both very horny but also extremely nervous at the fact that I'm not only about to watch my woman with another man, but I was about to have my first bisexual experience, a thing I honestly never thought I'd do.
She didn't let me have sex with her at first, as she didn't want me to cum before adequately pleasing him. She had a way of soothing me though, while pushing my limits, and making me somehow enjoy it as much as she was. Fast forward a couple minutes, the foreplay is over, my wife and I have spent the past several minutes sucking off her ex lover together, and it's time for me to bend over. This was easily the most nerve wrecking part by far. I buried my face in the bedsheets and clenched my jaw when I felt the tip of his dick push up against my asshole. Meanwhile she just stroked my hair and softly told me to just relax and breathe. I really thought this would hurt like a bitch especially since his dick was even bigger than mine. But as SOON as he stuck his cock up my ass, not only did I let out a very loud involuntary moan, I immediately shot quite literally the biggest load of my life. It was the most embarrassing moment of my life, albeit one of the most pleasurable. My face was literally bright red as she burst out laughing. She didn't even have to touch my dick. I'm still dripping cum, and she's still laughing hysterically, as this guy gives it to me from behind. After she laughed her ass off she told me "I knew you'd end up liking it, I just didn't think you'd come around THAT fast!"
I didn't even get to fuck her that night, as one stroke of her ex's cock is all it took to finish me. Basically he just ended up fucking us both. Humiliated as I was, my wife absolutely loved the experience and still talks about how hot that was. All in all I don't regret it, she teases me about it here and there but keeps the secret safe between us, and like I said, I'm happy that it made her happy.
