This happened a while back. I (M) was hanging out with an old friend (F) after having just been through a rough breakup. We met at a restaurant and the talk turned quickly to sex, which was unusual because we’d never been fwb. Both of us were getting worked up in the restaurant, and she had/has a bf, so we decided to call it a night.

As she drove me home, she told me that a longstanding fantasy of hers was to make a man cum in his pants. While this wasn’t a kink I’d ever thought about, I was horny enough at that point that I volunteered to make her fantasy a reality. She got extremely excited by the offer and immediately pulled the car over and started dirty-talking with a new intensity, while I rubbed my cock through my jeans.

I live in a neighborhood with a lot of bars and restaurants, and it was Friday night. We were parked on a busy street, and I was very conscious of how many people were walking by the car as my friend worked me up into a frenzy. When I announced that I was going to cum, she reached over me, opened the passenger door, and ordered me to get out, even as I felt my cock pulse and cum drench my underwear. I fought to keep my composure as she drove off, leaving me to walk down a crowded street over a block to my house with a noticeable erection, a huge stain on my pants, and what must have been the guiltiest look on my face.
