I told her that I would expect her at my place next Saturday at 6:00pm. So there she is. We have a short conversation before I ask her if she likes to...drink something. She replies positively, and I lead her to the kitchen, telling her to help herself. She helps herself for a drink and pours me one. We go back to sit in the living room. I can sense her nervousness. Her voice sometimes trembles when she talks and I figure out she is excited and apprehensive. She has no clue about what I have for. " I`m sure I will. Let`s get started, Stan."We did. I was the first to cum and my sister followed soon after. She was panting as she gave herself several orgasms. When we were finished Anne said "You were quite right. I really liked seeing you with a full hard-on. It`s big and is still right up even though you`ve ejaculated. Let`s do it again when I next come to you.A week later my sister came to me and in my lounge we again stripped naked and went out on to my lawn."I hope you won`t mind,. He wrapped his arms around her and pulled her in with her neck it against his body. They started making out and she dropped to her knees and pulled out his cock. She gave his cock two or three deep throat’s and then popped it out of her mouth and My Aunt got up off of her knees. My Aunt turned around facing her back to my Uncle. She was facing away from me, so got a great view of her asshole and cunt from behind. My Uncle grabbed her by her right hip, his cock with his left and he plunged it. " Tom. I could see all this, but you couldn't see me, it was right in front of me, your back was to me, and her eyes were closed, it was so exciting to see, I had to close my eyes sometimes..Bonnie licked the end of your dick a lot, then she made her mouth go all the way down your whole dick, to your balls, Tom. Tom, Bonnie sucked your balls. I thought that was the dirtiest thing I had ever seen. But then she moved around and got behind you .....Tom, I almost came when I saw this, but Bonnie.
