This happened when I was in the final year of my university and was made head of a debating club. I had to meet with the Assistant to my Department Head every Friday from 6-7PM to report on and plan future club events. Over the course of a couple of months we grew very close together and I slept with her at her house. She was married at the time and didn’t have any children. Her husband worked as a travelling salesman for a heavy machinery company and was home for 2 weeks every month, spending the other two weeks on the road.
Our affair went on for around 2.5 months and we stopped when she got pregnant (I’m sure it wasn’t me because I wore a condom every time, except the first time).
I’ve left out all the sexual details (I’m open to talking about them in detail), ask me anything further if you want to know more. I’ll answer all questions.
