He stopped for a moment, looking at me. "What?" He asked."Something you'll like. But you have to come now, and you have to be absolutely quiet."I was ...rying to keep from shaking, I was so nervous about what I found myself doing.He looked at me with that mischievous smile and gleam in his eye, wondering what I was up to, but was ready to follow.He wrapped his towel around his flat stomach as he followed me out of the bath.Just before we left his room I turned to him. "Absolutely quiet or we'll. She was urging me to stop that. But her urging felt in deaf ears.I kept on pumping her ass. At one point I pulled out and that left ass gaping. When the gap was slowly getting to close. I pushed in again. I stood up on my feet and while half squirting position I was humping her ass from behind like a mad dog. I reached ahead to cup her tits. Squeezed them hard. Pinched the nipples hard. And saw her looking at my face over her shoulder. There was an expression of pain in her face , but she was. It was very fine in fact, but it was barely three or four days total within every six months.

There was so many of our extended family about us - none realizing what was poking my backside.Tearing my eyes from my grandchild I slowly looked. She felt like a whore, and sadly she was, to her surprise oh so very proud of it!She collected herself, knowing he was in the dark, she began to explain, saying she was sorry but she felt just too bruised internally to have him inside her body while she explained what had happened, but would he run her a bath, then she would tell him all about it, as she soaked away her pain. The bath ready he helped her from her bed, stiffly he helped her to the bathroom, then from behind her, he gently lifted.
