Home isn't Safe *Yandere older brother*

When she was growing up, she followed her big brother around like a little puppy. Now she's grown up and a young woman now. Coming home from school, she sees her big brother is back home. She was so happy to see him. Until one night their parents go out, so he teaches her how to get high and drink.
She becomes so high and drunk he is finally able to take what he's always wanted from her. Now she's stuck under his grip and can't escape.
