” Between seeing her fuck herself and her imagining it was me I got another hard on right there in the doorway. As I stood there with my throbbing d...ck watching my grandmother ram a dildo into her and calling my name an idea came to me. I could either enjoy the show from afar, leave before I saw the climax, or join in the fun. I admit the idea of fucking my grandma sounds gross but when you’re in the moment it just felt right.I bent down on my hands and knees and crawled into the room. I couldn’t stop looking at them. They were both thin, like me, with boney hips and blonde hair held back in ponytails. Their boobs were just starting to develop, with perky pink nipples. There pussy’s were just staring to grow whips of hair. They had deep tan lines where their swimsuit should have been. They were the most beautiful things I have ever seen. Laughing and splashing. I stood there transfixed. As I watched one of the girls pulled the other close and kissed her. First a quick kiss,. And then realized that they were hardening! Each was pressing more and more against the thin nylon material, and the more she stared the harder they were getting. She was getting turned on by the sight of her tits ... and the idea that Richard Baker had been looking at her!!! She ran her hand over her right breast then quickly over her left one and a moan escaped her lips. She quickly looked at the wall, as if the girls on the other side might hear. She dropped her hand and concentrated on. "I saw a wicked gleam in Kelli's eyes I'd never seen before. She was looking down at me as she kissed her lover deep and full on the mouth, his hands exploring her ass. It was then I knew that she wasn't the least bit regretful of what her boyfriend was doing to me. That, just the opposite, she wanted it as much, if not more, than he did.* * * I guess I hardly need explain that it was the worst night of my life. My wife was upstairs fucking another man in our bed while I lay in the basement.
