Me and my boyfriend are in a let's say "open" relationship, each of us fucks whoever we want, but we've never brought anyone home. there was this girl (yasmine) I was talking to, we teased each other by message, we sent each other nudes and moaned ok the phone together until the day she asked me to have a drink with her, I accepted, the day arrived , I went out and I was fine as hell, wearing my slutty blue dress, my makeup was good , I was freeesh. my boyfriend was strangely not at home and didn't tell me where he was going, anyway, I joined the girl she was cool we left the bar we made out and kissed and I invited her to my place, we arrived at the house I hear sounds of someone moaning, I see that it was a girl with my boyfriend,I saw him fucking her in a doggy position I left them alone to do their little thing and I went into the living room, me and my little girl, it was so exciting to fuck with her knowing that my boyfriend is pounding another girl's pussy. Yasmine asked me if we could join them, I wanted it to but I didn't know if my bf and this girl would like it or not so I just told her that I wanted her just for me and we continued our night. The morning they left together at the same time . Later Yasmine sends me a message saying that she ate the girl's pussy that my boyfriend was fucking,and invited me to do a threesome some day .
