PART 3. This takes place on the next day from Part 2. I am wearing my black stockings and lingerie under a black dress. I confront my stepnephew that last night was too close and this thing between us two has to stop. Just then, my stepsister walks in to see if we’re ready for dinner and the two of us say yes. After we got home from dinner, everyone had an amazing time and had a little too much Giggle water. My stepsister and her husband hit the sack in their rooms and I’m left alone with my stepnephew. I know the two of us should stop our affair, but I’m too horny and too tight to stop ourselves. I immediately go to my room and start to ride his cock cowgirl. I love how his cock stretches out my pussy and that I’ve never felt this way before. I hear my stepsister knock on the door to check how I’m doing and I get off my stepnephew’s cock to walk over to tell her everything is fine. But as I’m talking to her, my step-nephew comes over and starts to fuck me against the door...
