My parents remarried and my step-sister started living with me. She clearly hates me. Of course she hates me if I don't leave the house, don't take baths, and look at her with lustful eyes... But she's a really hot woman, so I want to get her somehow. So I put a little bit of aphrodisiac in the water she drinks every day to make her more and more sensitive, and I touched her so much that she couldn't resist, making her cum so much that I fucked her! My step-sister is getting more and more erotic every day, and she can't resist anymore!
