M18 I fucked someone in public and they were also in a relationship loved it so much to making this girl cheat

(Highly summarized) I had an FWB as a friend for a long while she was an bit older than me and when she got a bf she never stopped being slutty so I thought I’d have some fun with her so I started to sext/ flirt with her eventually we met up at like a bridge thing and we walked somewhere we can hide most of the action but have to cover up when someone walks by in short I railed her brains out and fuck If this is what fucking someone’s GF is like I wanna do it again
