I don't remember if he got them as a gift or at a very low price. They were three, I think, one of them was an Amazon-type bodyguard. The MC had sex with her and she was a virgin. She was very grateful because if no other master wanted her she was to be put to death.
I think the MC then became the target of a conspiracy.
I know they're very few details, but hope somebody recognizes the story. TIA.
Edit: It is set in the real world, the MC is an ordinary guy living in an ordinary neighborhood.
