We danced for a few hours. Jennie is a great dancer and we were having so much fun. Then, some creepy guy starts to dance in between us. God, I HATE t...at. Why do guys have to be so lame? I was in the middle of a turn and some guy slid in between us and started to grind against me. I felt his nasty dick rubbing all over my ass! He had his hands all over me and he was so gross. It had all happened really fast. I assume he had been watching us because as soon as he had an opportunity, he took it.. Finally, I thought I figured out what Ben was getting at, “So, if I understand what you’re saying, you think my boobs will get Dad in the mood to masturbate, right?”“Exactly”, Ben said, and he raised his glass as if toasting me for understanding.A thought hit me, causing me to giggle. Ben asked me, “What?”“Are you sure it’s Dad you’re thinking about, or do you just want a better look at my boobs.”He got defensive, “No, it’s Dad.” And then he let out a chuckle, “Of course, Bruce and I wouldn’t. I couldn't respond with words. I could only sit there, staring with intimacy, blushing, panting and moaning softly. Another giggle from my sister's mouth pierced my ears. "I should have known better than to ask that in a situation like this. You probably haven't even felt love yet." She finally removed the little thing, catching her socks in her fingers as well and striping them off at the same time, her body only clothed with her matching light-azure semi-see-through undergarments. She. "I stopped staring at her and stood back, gesturing for Cindy to come in. I closed the door behind her and I could already feel the blood flowing as I wondered at the implication of her words. Why was Cindy telling her mom lies? I felt the excitement growing because this could be good news for me."It is good to see you again Cindy," I said, pushing the door closed and moving towards her.Cindy's red lips smiled and suddenly she launched herself at me, threw her arms around me as she reached up.
