When i was 15 I went to stay with my Grand parents to help on the farm that summer. My Dad had a sister who was retarted and had never lived anywhere but with my Grand parents.She was about 40. My Grand parents slept down stairst and her bedroom and mine were upstaires. One night around 2 am I was watching a movie on my lap top with the sound almost off when I heard foot steps coming up the stairs. I turned my lap top off and lay very still. The foot steps went past my door to my Aunts door and went in. After a few minutes I heard the sound of the bed squeaking and my retarted aunt grunting and making all kinds of squeeking noises. I quietly slipped down the hall and a small nite lite was on and the door was partially open and my Grand pa was on her f****** her He grunted and pushed in her hard and I knew he had c**. I slipped back in my room and he went back down the steps.At breakfast it was like nothing had happened. This would happen 2 or three nights a week. One night after he left I went in her room and she looked at me and spread her legs and pulled her gown up. I got on and fucked her and c** was rnning out of her.One night I waited till he was f****** her and walked in on theem and turned the light on and scared the f*** out of him. He said you cant tell anyone about this. Your grand mother dosent like s** anymore so she lets me use your aunt Linda. You caan use her too but you cant tell anyone so after that he and I would f*** her anytime we wanted and my Grand Ma would just stay down stairs. I was so h**** at 15 I woulld f*** her 3 or 4 times a day. It was great and after that Grand pa didnt have to wait for me to go to sleep so he would f*** her early and I would have her the rest of the night. I fucked her every night and most nights 22 times. I started f****** her when I got up befor we had breakfast. Grand ma would clean her uop and was the sheets every day.
