Now I had to sit and get the strength to say what was in my mind."Getting fucked ... um ... by you ... isn't something I think would be ... that bad."...This is clearly getting out of control," he said softly.I just stared at him. I had offered to let a man have me. I was astonished. My head was whirling. And yet, because it was Uncle Bob, a man I knew and trusted and loved, I didn't feel like I was in any danger. Still ... it was just weird."Do you understand where this is going to go if we keep. Dad looked at her and she pushed him down prone on the couch. “No, Sherry,” he said but didn’t move. “This is wrong,” he said. “I know, but I want to suck your cock. We’re along and no one will ever know,” she said. Dad mumbled something and I heard his zipper. “Sherry,” he mumbled, “Sherry!” I saw her move down…she was sucking him now! Dad’s hands were in her hair, caressing; Sherry’s head was moving and I heard the sucking and Dad’s oohing and ahhhing… and ohgodding…Sherry’s hand went. He grinned. "Yeah, you like that don't cha?"He tied her wrists with cords that Susie saw were already attached to the headboard.Susie was spellbound. She could tell that Jennie was putting on an act, a game, but it was so sexy! Susie could feel her vagina quivering. She realized that she was holding hands with Saphron. She looked down and saw that Saphron was slipping the fingers of her other hand into her panties and was masturbating! Susie reached down and slipped two fingers into her. That is amazing oooooooh."I began to stroke in and out slow at first then with her prompting faster and faster.Her legs tensed up and she held me tight then suddenly after a moment of not breathing she screamed,her body convulsing.My cock was pulsating dumping cum into the condom.She was stiff as a board holding her breathe again before crying out.Then she relaxed saying "fuck man that was ..........I don't know what to call that.My god."I pulled out and started for the bathroom to get rid of.
