Family Bonding: Show Me What You'd Do If She W...

Story - I can't believe they made me kiss my stepsister at a party! Sure, I wanted to do that ever since I met her, but I never thought of actually crossing the line. Her lips felt so soft and warm that I couldn't stop thinking about how they would feel around my cock, and I could tell how horny she was, but I still didn't know if I should fuck her until we got home. She lay on the couch, raised her tiny dress to show me how wet her pussy was, and asked me to show her what I would do to her if she weren't my stepsister. How could I have said no to that?! My dick had never been that hard! The next few days, she kept tempting me. She even hid my car keys in her pussy, so I would have to put my fingers inside her. Just as I was about to cave and fuck her, our stepmom got into the car. I was so embarrassed, but she said she knew what we were doing and she liked it. She spread her legs and told us to keep going because she was fine with it. I was still not sure about it, but my stepsister didn't hesitate to put my dick in her mouth! My stepmom was so horny that she ripped her tights and touched herself as my stepsis kept giving me head. Later, they both called me into my stepmom's room. They were in bed, licking each other's hard nipples and wearing nothing but lingerie. They wanted me to join them, but should I have done it? I didn't care anymore. I had to fuck them.
