I [f] mutually masturbated with my friend [m] and he well cam on me

My friend and I have always had a very sexually charged relationship. We both have always found each other attractive, but have never acted on it, despite flirting quite heavily. We both have no interest in being with each other romantically. It’s all physical. We both know this, and we’ve definitely masturbated over each other before, just never explicitly (more as in, we’d talk about something sexual or I’d send him some risky photos and then he’d tell me he’s going to watch some porn, and I’d often touch myself over the thought of that).

The other day he was over and we smoked a little bit. We were just chatting and somehow the topic moved into sex. We are usually quite open about these things, but this time he surprised me by asking what my biggest fantasy was. I immediately felt myself get a little bit flushed because I knew that if I told him, he’d be turned on too. Because my biggest fantasy is someone coming inside of me. I decided to tell him. Why not?

“It’s explicit but… I do fantasise about a man coming inside me”.

“Oh fuck”
