Suddenly, my little sister by marriage appeared. She's the type who loves to tease guys inexperienced with women and is a huge fan of sex. She's got massive tits too! She keeps clinging to me, pressing her chest against mine, acting like she's into me, enjoying my reactions. I get hard every day because of her! But then she suggested we take a bath together, and now I'm in big trouble! In the cramped bathroom, her huge tits and ass keep rubbing against me, making me fully erect! Seeing my erection, she makes a lewd expression, gets aroused, and demands an immediate blowjob and fucking in the bath. This slutty girl even forced me to finish inside her!
