My College Girlfriend

We were very young when we got together in college. We were full of sexual energy and the times encouraged freedom and exploration. We were living with another couple in a rented house. We were all pretty open around each other. One night I told my girlfriend that I wanted her to sleep with our male housemate and also told him he should sleep with her if she wanted.

A few days later, she took him to bed and they made love. When I asked her if she had fucked him, she said she had and that it was good and his girlfriend was good with it. It was arousing to hear her describe their love-making and I fucked her as she talked to me about it. It was a one-off she said.

Several months later, I came home early because a class had been cancelled. As I came in, my girlfriend was fucking our housemate on the floor of the living room. They were startled, but I told them not to stop and I went to my bedroom. When my girlfriend finally came in, I fucked her really hard. As it turned out, she had been fucking him nearly every day when I was in class. She admitted he'd cum in her over a hundred times. I felt betrayed. And even though I had occasionally slept with his girlfriend, I was angry with him for taking advantage. Until, of course, I realized my girlfriend wanted to fuck him a lot.

I left and found an apartment by myself. My girlfriend apologized, but I couldn't get over it. In retrospect, I think I was okay with her fucking our friend, but when I lost all control over her fucking him constantly, I couldn't take it. So, it was my fault really.
