Sisters boyfriend is a bully

Your life, mijo, but I wouldn't go.

There has to be someone out there who gets why I'm not fighting back
Does anyone know where I'm coming from?

You are trying to convince yourself that this situation is a good thing, but it is not okay for someone to physically bully you. I think physically fighting back would be a bad idea, because you could get hurt since this guy is stronger than you. Have you tried telling your sister you don't want to go there, or telling this guy not to do this to you?

I've tried both those things and they both just laugh at me and say there is no way that I'll be able to get out of being bullied.

I have talked to my sisters boyfriend and he has agreed to limit the hanging wedgies to 4 times a week for around 2 hours a time. I also asked if I could wear boxers, but he wouldn't let me, so I'm stuck with wearing briefs.
