[MF] I (29M) made my ex coworker (31F) finish 5 times while we were high, before her boyfriend came over

Long time lurker but first time poster. I had a fun experience some time ago so thought I’d post about it. This turned out a lot longer than I thought…

I met her (call her Z) at work a few years ago. Z is 5’7 slim, long brunette hair, with C cups and perfect ass. She was always flirty with me and we occasionally hung out as part of a group after work but nothing ever escalated, we were both always in relationships. A couple of years ago she got another job and left, but we kept in touch. A couple of months ago, she had a party and we made out with each other (in front of her boyfriend, who was fine with it!) as part of a game.

Fast forward. I am in an open relationship and my partner is away for the weekend. We are about to leave the country for a while so I invite Z to go for a drink near my place to catch up before I go. But just before we meet she suggests going to my place instead as she is “a bit tired” and doesn’t feel like going to a bar.
