I told her not to worry I would take good care of them and she said goodbye. I grabbed a soda from the fridge and went downstairs to join Steven and w...ited for Cathy and her friend to get home. I sat silently watching TV with Steven for a while. A few minutes went by and he said this movie was boring and asked if we could find something else to watch. I said it was fine with me and started flipping the channels. He looked at me with a smile and said "Can we watch some dirty movies like we did. I felt something brush against my balls, I looked over Mandy’s shoulder and saw Dan on his knees, he was playing with Mandy’s pussy and she was quietly moaning in my ear. “Mmm that’s feels nice,” she whispered. Dan stood up and took his cock in his hand then moved forward. I knew what he wanted to do so I pulled Mandy up a little more off my lap. “Thanks Tim,” Dan smiled I spread my legs so he could get closer. “Fuck that feels good Dan,” Mandy groaned. I figured Dan had pushed his hard cock. "Has that ever happened before?" Yes and yes," I confessed. "So tell me Mrs. C, does that promise I made work both ways? I mean I don't talk about today and neither do you?" That's fair. Today never happened then," she agreed. "So talk to me about this Billy. Why are you so ...stiff?" It's because of you Mrs. C," I told her. "I think about you a lot, you're so beautiful and all. Then I go to my room and take care of it, if you know what I mean." Oh I know exactly what you mean," she replied.. That should have given him pause for thought. What nearly naked girl, finding an unknown man standing on the threshold of her bedroom leering at her, wouldn't scream? Or at least shout. He had put his finger to his mouth; but she hadn't even started to scream. She'd looked at him. There was no point in screaming, she knew that."Well, dear. Aren't you pretty?" She looked towards the door as he came further in. He saw and shook his head.He was in the house, he was nearer the door; there was no.
