Your step-sis walks in one day to catch you indiscreetly watching her online porn videos. Pissed, she slams the computer closed and tells you to mind your own business. You tease her, telling her she’s a slut- all the while, she’s noticing your cock is hard and getting even more pissed. Things eventually progress to her sucking your cock, and after more protest, she ends up telling you to put it in her. She continues to tell you what an asshole you are although she’s moaning and her eyes are rolling back of her head… Things end with a big load of your cum in your sister. She’s pissed and humiliated afterwards and tells you to fuck off and that she didn’t mean any of that shiit she said. You’re an asshole, and she didn’t enjoy it…
