When your mom cheated on your dad, her new boyfriend moved in before you dad had even moved out. He gave the "New man of the house" speech literally right in front of your dad. He was such a dick and your sisters were always bitches, so you didnt get why
Before she banned you totally from sex and locked your dick in a cage - she wouldn’t let you cum without a condom period. Now, your best friend gets to cum wherever he wants to on her. I guess that’s what he gets for being a real man.
She knew she is being raped ,she felt her rights violated ,she felt guilt of cheating ,she felt totally ashamed for embracing the man tightly in her arms who raped her and is fucking her raw on her marital bed.
