Out of the corner of my eye I caught a glimpse of someone peeping through the gap in the door. It was a female I am sure. Then it was time to try "Som...thing new" "OK, something new to try" she said, " I am going to blindfold you for this to enhance the feeling" The blindfold of a scarf was tied tight around my head. Then I felt the enhance feeling, the lash of a whip. Bloody hell that hurt I thought. " Now what was that like" she giggled. "It hurt very much Madam" I quickly replied. "Not to. After a little while I stopped again and noticed that the boy and girl were over in the corner and were laughing and playing around. He would try to jump on her shoulders and push her under and she would come up screaming and laughing at the same time. Then he would dive under and come up between her legs, firing her up in the air. I tried to watch them without looking as if I was perving on them -you can't be too careful in swimming pools. They were a nice looking couple; couldn't have been. I felt betrayed to my core and was determined to get away from the lying, cheating bitch. I was not going to let her fool me anymore. But in order to teach her a real lesson, I knew that I needed to get solid proof of her infidelity.However, I was also determined to ruin the date that she was going to have later today. If she did not want me anymore, then what could annoy her more than giving her a good morning-fuck before leaving for her date?I lay quietly for some more time before I heard. They had a great time with each other, frequently. I had only seen Mom naked once, when I was fourteen. I had walked into the bathroom to piss just as she climbed out of the shower. I jerked off three times that night thinking about her wonderful body.Several minutes passed as I watched my uncle fucking his sister, my mother, and I kept stroking myself as I watched. Finally he groaned and added his load to her fuck hole and then pulled out. I had no idea how many loads she had filling her.
