During my junior and senior year of college I had my own dorm room. I used to bring a few of my sister's friends out to my room and I'd pay them to give me blowjobs. Sometimes 2 at a time. It was actually pretty inexpensive.

It's not that I couldn't get a girl. I had girlfriends and hookups. I'm a decent looking guy, I'm 6'4", and I've got a nice sized cock. It's just shy of 8 inches erect, and decent thickness. There was just something that felt so good and dirty about that setup. Anyway my sister found out and put an end to it, but eventually I talked her into doing it instead. I offered her $100 bucks if she'd blow me, and she didn't hesitate. Then it moved to 50, then 20, and then she was doing it for free because she enjoyed it. We had never really been that close. It was more of a sibling rivalry. But at that point, there was a lot of physical lust going on.

After a couple months of blowjobs, we started fucking. Our first time was actually back at my parents house, in their bed while they weren't home. We used condoms for probably 8 or 9 times. After that, we were both so into it that we just stopped using condoms. It didn't take long for her to get pregnant. It was a terrifying yet completely exhilarating reality.

We kept fucking during her pregnancy. She looked even hotter with her baby bump. However, everything came to a screeching halt when she had a miscarriage. We fell apart after that.

I moved to another state. We're both happily married to other people and have kids.
