I had begun to have an interest in my sister though. She had been sunning herself on the back deck all morning and had come in from the heat of mid day when I was sitting down for lunch . My usual lunch consisted of a very large sandwich with lots of meat and about a half gallon of milk. Jenna came into the kitchen wearing a very skimpy bikini and my cock went hard as a rock. It was like that a lot around the house lately. My mother had taken to wearing a relatively shear robe around the house in the evenings and very short shorts with a halter-top on the weekends.
