Without going into detail, a couple years ago while cruising on Scruff I visited a man twenty years older then me who wanted to suck me off, who was partners with the guy that became my boyfriend. They were in an open relationship where the older guy would blow random guys all the time and do drugs like meth. I visited a few times after, then I was in a position where I needed to find a new place to live and they invited me to become a triad with them move in so the older guy could keep my balls empty. Fast forward a while and the older guy got increasingly unstable as he wasn't telling his doctor about his drug usage and was on a lot of meds that didn't react well to him missing doses, and my current boyfriend was going to engineering school and badly needed a level of stability and did not want to deal with the imagined Russian Mafia hiding in the tree across the street. It eventually reached a point where the two of us had to move out and find our own place. The old guy got more unstable and his friends and doctor eventually found out about the drug use and had to completely rework his meds, which led to him attacking the people living in the mattress and going through a bad situation that lead to his death.
