We confronted my wife about this and she broke down and confessed. I said to her step dad that I would make sure she was punished for this disgusting ...eed and he asked if I would object to him carrying out the punishment as it affected him. I of course agreed to this, as my wife really did behave disgustingly towards her parents.We decided to get it over with then and there and my wife was made to go into the garden and break off a suitable switch for her punishment.It was decided she would go. "I must have looked as stunned as I felt, because Diane laughed, and said "Yes, you idiot, she's either getting, or already has, a crush on you. Didn't you know?"I just shook my head, and Diane went on "We were resting from sledding, and just sitting there drinking some of the soup your mom made for us, and we got started talking about guys. Of course, all I could talk about was you, and Susan finally started talking about you, too - how nice you'd been, and how polite and everything, and even. She started humping up and down on my cock, taking about 5 inches into her each time. I was in heaven watch her tight white pussy riding up and down on my cock. She was so tight around it; even in the dark I could see her pussy lips surround my cock like a big rubber band. As she pushed down on it, her lips would go up almost into her, then as she lifted off my cock, her lips would stretch around my cock and slide up puffing out. She started grinding on me and I could tell she was getting. He entered her once again and they both started to moan and make a****l like grunts as once again he did his best to give her the fucking they were both craving. He moved his hands from her waist to her shoulders, driving her back to meet his thrusts, her grunts and moans became little then louder scream as she orgasmed once again. His movements slowed as she recovered. He ran his hands over her back and down to her ass cheeks. As he squeezed and caressed that ass that he loved to watch so.
