HUNTA-863 While Our Parents Were Away On Vacation For 3 Days, My Big Stepsister, Who Is A Prim And Proper S*****t Council Member At School, Ordered Me Around And Fucked My Brains Out

My older sister is a super serious class representative and a typical honor student in both appearance and content. But I was ordered by a bullied child to put her sister to sleep using her sleeping pills. Then the bullies put her sister on her first day and she was asleep and fucked. She is on the second day, she hates it, but if she continues to fuck her, she will start to feel it. On her third day, her older sister transformed into a ridiculous cock madness that she sought herself. I can't believe my sister can be so erotic and I don't want to believe it!
