My sister's boyfriend is a jerk
I'm 15 and my sister is 17. Due to our parents work schedule, we are home alone often. My sister has always invited boyfriends over and they will go to her room and have sex. As long as I leave them alone, she will do my chores without question.
She recently started dating a college guy that's an arrogant jerk.
I'll be in my room gaming with my headset on. He will knock to get my attention and say. Hey buddy, I'm going to fuck your sister so leave us alone. When they're finished he makes a point to show me the used condom toss it in my trash can and say. We're finished. It's getting crazy now. They don't close her bedroom door and are loud. He will carry her up and down the hall so I can see them.
I think he wants to get you more directly involved somehow. How would you feel about that? Have you ever done anything with the used condoms he leaves in your trash can?
Sis takes out the trash as soon as he leaves. Says she doesn't want mom and dad to find evidence.
It's not that. They like people to watch. He brings his friends. They stay in the living room and he carries her in there. They watch while he pounds her. She enjoyed it and I can hear them cheering. I got caught looking one time and he called me out and told me to come watch sis get fucked. She acts weird for a few hours after he leaves. Like I have to tell her to put cloths on.
Start taking pictures of them. If she is doing your chores now, think what she will do when she finds out you can send your parents proof.
Just ignore him as long as your sister wants him. If you try to change things it will lead to a poor relationship with your sister. Family is worth more than anyone else.
