I got home walked indoors and I could hear her upstairs moaning I thought great she knew I was home and got starting but as I quietly walked up the st...irs I heard her calling out "me Dennis that's it baby fuck my arse hard I love you in me "I thought what the fuck why is she playing with herself calling my brother's name as I got to the bedroom door it was open a little and when I looked there she was naked on her knees and my brother was behind her fucking her hard.I couldn't believe it first. I don't get it."Reaching out I took her hand and said, "You've worked really hard at school, and you've been the best daughter this week, so for the rest of the day I'm letting you choose if you want me to do things to you, or you do things to me. Here, in the car or anywhere."Her eyes popped open in surprise as she stared at me. She blinked a couple of times as she processed that, then I saw her mind start running through the possibilities."So...so you would...you would do what you did last. My eyes were transfixed on her delicious arse cheeks and as she moved up and down between dishwasher to shelves - her booty gave out a scrumptious wobble but only ever so slightly. I stared deeply at her arse and thong trying to picture her undressed. And not for the first time she looked back...and caught me staring at her arse!"so you like my arse do you babe?" she said, "I always catch you having a good old look you know". I felt embarrassed - not for looking, but because I had been caught!. With each gyration of this incredibly slow torture, I would lick more and more of her pussy juice up toward her ass, and with each new lubrication, I imagined the dildo was sneaking further, but ever so slightly, into this little girls ass. Soon though, I realized that it was still only in about two or three inches and I felt disappointment that it would probably not go much further. But just as I was considering giving up as I had had to on her pussy, she began to press up her butt and whimper.
