I'm actually a sheltered and innocent woman. I live in my boyfriends harem with his other girlfriends.
How did you even end up there?
I tried really hard for this, it was interesting to me. I enjoy it.
Sounds like a tricky situation. In my opinion your boyfriend shouldn't expect you to put up with that. I think talking with them about the situation could allow you not to have to deal with this anymore.
There is this one girl that's very disrespectful about the harem. Makes me upset because I'm always doing my best and she just throws me under the bus.
I think that you need to show that you have respect when it comes to relationships and let this girl know that throwing you under the bus is not okay. You should not let yourself get walked on.
