The taboo part I actually liked was everyone knew. I was the instigator in most of it. I thought it was super hot watching her boy get jealous fucking his roommate.
Then I said ok to whenever and that was fun, skipping a ton here but eventually it got crazy and I got mad about something and left and when I tried to fix it it couldn’t be fixed.
She left a month before me and I fucked quite a bit but everyone knew and she was embarrassed. We didn’t go back after that and short story is I ok’d a coworker joining us in bed and I also liked it and he was shy at first
