I changed night suite. I said you can sleep now, I will watch tv until I get to sleep.She smiled and said, don’t act too much, and silently she went...to her bedroom. She kept the light on. After 10-15 min, she called me from the room and said, you are still not sleepy. Then I switched off tv and light and went to her room. She said another room has some dust there, you can be comfortable here if you don’t mind. That was obviously a green signal for me.I switched off room light and got on her bed. Said she would be glad to. She asked me exactly how to do it and told me to lower my pants and underwear. As I thought about how she would do it, she kept her hand on my bare butt cheek. blood was flowing into my dick but I wasn’t quite hard. Also I didn’t feel too uncomfortable about my nakedness and my dick since she invited it.I told her that I wasn’t sure how to describe the butt rub. She asked me if I would show how to do it on her. I liked the idea and told her so. She removed her. Violet began to gyrate her hips, slowly and sensuously, feeling every small movement of the muscle filling her guts. For a few minutes, there was only gentle gyrations, and the small token thrusts on Kathleen’s part, all that she could manage in this position. They made love to one another, as only sisters in this specific situation could. Violet’s orgasm built slowly but concretely, every movement of Kathleen’s cock stimulating every inch and every degree of her vagina, including her g-spot.. . as if we had left the whole world behind… once we were back to our senses we headed towards the bed and I started kissing her on her cheeks… and running my hand exploring her body… it was the best moment when she lay on me smooching… and I had I had my hands on her ass cheeks massaging them and pressing them harder towards me…I started kissing her neck embracing her really hard… I was sucking her neck and biting her neck muscles and ears… she was going wild with the moment and was letting her.
