I was the shared boytoy for an older married couple for a few years. I rented out their basement apartment while I was at college.

I was an inexperience horny 19 year old so it wasn't hard for the wife to seduce me. At first I thought I was cucking her husband, but then she said her husband wanted to watch. Him watching turned into threesomes where we were sharing his wife... and then over time they both seduced me into trying more and more gay stuff until eventually it was more like they were sharing me.

Even though it started out as a purely sexual thing, I ended up kinda falling in love with both of them. When I graduated, instead of getting started on my career I stayed with them for a couple more years, playing at being their boywife and taking care of the house while they both worked.

Unfortunately, while they had feelings for me too, I was still the third wheel. So when they decided they wanted kids, they couldn't exactly keep their bi boytoy around anymore.
