A married female work colleague got really into me a few years ago and we started flirting back and forth. She was a little bit older than me and was beautiful, petite and redheaded. I used to go to the work gym a lot after work and one evening she asked me to meet her at the work car park after I'd finished at the gym

I sat in her car and just assumed we'd chat and maybe kiss even though I knew she was married, but she was really hot and I found it exciting. She actually pretty quickly told me she wanted me to make her pregnant because her and her husband had been trying and it wasn't working. Of course this was the hottest thing I'd ever heard, I got instantly hard and we moved to the back seat where she climbed on top of me. She was so wet already and I was so hard and horny. It didnt take long before she begged me to cum and I exploded inside her. We sat there for a while kissing and before I knew it I was hard again. I lay her down this time and we fucked long and hard until I came again, filling her with two loads

She later asked me round to hers a couple times when her husband wasn't there. We'd get drunk and fuck all night making each other cum. Then at work the next day we'd pretend nothing had happened

She eventually announced that she's pregnant not long after. I was never sure it was mine of course but there's a good chance it is and no one has a clue
