So I am solidly bisexual. When I say I swing both ways, I really do mean I have no preference… which is why this is one of my favorite sexual encounters I’ve ever had.So I had been dating this dude for several months. I’m still friends with my ex-girlfriend who is objectively one of the hottest women I have ever seen. However, she’s also a bit crazy and overtly sexual so my boyfriend and she always had an awkward relationship because she was a little too flirtatious and loved to bring up our past sex life. She had joked about having a threesome, but I knew she wasn’t interested in men so I never really took her that seriously.
Sidenote: there was this one moment a few weeks before this story took place when we were all quite drunk that she asked if I liked being dominated with men as much as I did with women and they seemed to have a weird bonding moment over it. That was the only time I really thought they were both possibly interested in a group, but I still never thought it would pan out.
