It was Saturday, and I met my stepsister in the sunlit bedroom of our parents. There was a spacious solid bed, because our father was a very passionate boar of fifty, and our mother, as a proper devoted wife, almost always obediently pleasured him. Today, however, my dear stepsister will perform at it. She brought some sexy cloths to the bedroom so she could show off nicely in front of the camera and make me think. At first, the setter dressed in her father's flannel plaid shirt, her lace a black thong trying to hide her pussy. The measurement could begin. Surprisingly, the sight of his scantily clad stepsister did not cause me any problems. Soon, however, I needed one of her firm, round breasts to peek out of my shirt and my nipple sticking out nicely. “You need to relax a little so I can best estimate your measurements,” the stepsis urged me.
