non-ethical monogamous situationship

So … sexual slavery?

I’m having a hard time coming up with another situation that fits that description.

I met my first girlfriend that way, we’d go hunting for crabs in the wilderness by day and then sell our catch at the marketplace. It was hard being online at the same time but we made it work. We built fires and prayed in the evenings under the starry sky, and fell asleep in each others arms, until that fateful night when I came back from my fishing trip to find all her belongings in a single pile, surrounded by blood. I feared the worst, but kept hopeful and waited. My patience waning, I finally ventured out of the wilderness and towards the reset point, where I found her… outside of a cave garbed in dungeoneer equipment mumbling nonsensical words about grinding. :'-(

I would make money in UO sometimes by logging into a female character and “bowing” in front of people to make it look like my character was performing oral sex. You could also spam “bow” while the other player spammed “salute” while standing behind the first player to look like doggy style sex.
