My first married woman

It was the first day of my first semester of graduate school. There had been an orientation of new graduate students, a meeting with the dean of graduate studies and then a lunch at a local restaurant. I ended up sitting beside a young married woman beginning her master's degree in English literature. Her husband was a teacher at the local high school. It was the Friday before the beginning of classes, and during our conversation she told me her husband was going out of town that afternoon with his students for a sports tournament and would be gone until Sunday afternoon. She invited me over to watch a movie on television. At the time I thought there would be a group of us and it never crossed my mind she was inviting me over for anything other than watching a movie with a group of friends. But when I arrived I found that I was the only one. She put out some snacks and offered me a drink. She turned on the TV and we settled on the sofa to watch the movie. The move had only just started when we began making out, holding hands and kissing. She moved my hand to her breast and then placed her own hand on my crotch, tracing the outline of my hardon. She told me she was on the pill so we could have sex and I needn't worry about her getting pregnant. We were soon naked and fucking like rabbits, taking short breaks after each time I short my load, fucking three or four times that night and two or three times the following morning before I finally left. After that we would meet two or three times during the week and on the weekend whenever her husband was out of town. A couple of months later, her best friends, another married woman also working on her master's in English, showed up one weekday afternoon at my apartment. She told me she'd has something of an infatuation for me since the start of the semester and wondered it I had any objection to having an affair with a married woman. I was sure her friend had told her about us and our fooling around, but I played along, telling her I had no problem with having an affair with a married woman, especially one as pretty and sexy as her. We went to my bedroom. I asked her if she was protected or if she wanted my to use a condom. She finished peeling off her clothes and jumped into my bed, telling me she was on the pill. She stayed for several hours and we fucked two or three times. For the next two semesters I was meeting both women several times a week. They knew each others schedules and arranged to not show up at the same time--or so I thought. Years later, I hooked up again with one of them, and she seemed not know anything about my having had an affair with her friend. A few months later I hooked up with the other one, and she, too, seemed not to have known. Neither one seemed at all surprised or bothered by it, and I've since suspected that they'd both been having affairs with a number of other men.
