I sometimes would catch a glimse of her boobs in the mornings when she wore a robe making breakfast.Friday night Bobby and I had crashed early after p...aying ball all day and I woke up and needed to pee. I got out of bed and opened the bedroom door and there was a light on in the bathroom. The door was partially open and I slowly moved down the hall and until I could see in.Standing in front of the sink was Bobby's mom wearing only a blue bra with black straps and matching blue panties with back. Like - - my sister sometimes does that to me - - and like she says it gives her a nice warm feeling between her legs too - - but like I haven't told her that it does the same to me too." she explained, while trying to regroup herself."Well, the next time she does it you should tell her that you do enjoy it and that you want to do the same with her breasts. You may both be surprised at the result." I explained to her."Do you need to demonstrate anything else?" she asked, with a curious tone."Of. "Mmmmph! There it comes! Give me that hot cum, baby!" she whispered.I was not pulling out of this ass. I pushed my cock deeper inside, squirting and pumping my whole load in between her wobbling ass cheeks. And when I pulled out, my last little drip of cum ran right down into her ass crack too. This huge, fat-assed woman gave me one of the hardest cums I had ever had in a long while.I was tired and a little out of breath so I laid down on the bed next to her. But even though I did all the work,. Dad wasnt home. My older sister Laura was on the phone. My two younger sisters, Meloney and Leslie, were in the living room. Meloney and Leslie were twins four years younger than me. Whole Laura was two years older. I decided to use it on one of my younger sisters. I pushed into Leslies mind and told her to come upstairs. When she got to the stairs I told her to come to my room. When I heard her foot steps coming down the hall I started relaying my list. I repeated the list fifteen to twenty.
