Has anyone ever subbed for someone they knew irl?

So I have been into a findom for a few years now and I have this fantasy where I submit to someone I know personally. Part of me would like them to not know it’s me and part of me would like them to know it’s me. It just really turns me on to think I’d be sending money to one of the really hot girls I knew back in school. Has anyone actually done this and how did it go? Did you find out they were a dom or did you just reach out to them and ask to send?

I’d also find it so hot to sub to an OF of someone I know too lol
