My stepsister comes into the room. She was going to a party but for some reason she changed her mind. Suddenly she came closer and started staring at my belly button. Then she started touching it with her finger and caressing it. I froze in surprise, but I liked it and it started to excite me. Her big tits were hanging over me and she was licking my belly button. Suddenly, she pulled my panties down and grabbed my hard cock. My stepsister started sucking my cock, continuing to poke her finger into my belly button. Then, she took my cock in her hand and started jerking it off, and with her other hand she was fucking my belly button. It all looked really weird, but I didn't care. My cum spread all over my stomach and got into my belly button. She played with her finger a little more and then seemed to wake up, got scared, brought her finger to her mouth and ran away. What was that?
