My little stepsister is angry, to cheer her up I fuck her in the ass until she screams.

My stepsister, Aria, and I were always fighting. She hated me for reasons I couldn't understand. Today, she found out I hooked up with her crush, and she was beyond furious. I tried to apologize, but she just shouted at me and stormed off to her room.Hours later, I heard a soft knock on my door. It was Aria. She looked so vulnerable and sexy in her little black shorts and tank top. She burst into tears and threw herself at me, sobbing into my chest. We fell onto the bed, our bodies entwined.Suddenly, she sat up and pulled away, wiping her tears away. She glared at me defiantly, her eyes flashing with anger and desire. Before I could react, she grabbed my hand and pushed it towards her ass. I hesitated, wondering if this was a test or a genuine invitation.
