She alterAbhinavd licking and sucking and stroking his cock, and it stood at full attention for her.My husband and I moved slightly to the side of the...window, where we could stand up and look in from an angle. I unzipped my husbands pants and let his rigid cock out. It was standing straight up and dying to be stroked. I stood behind him and wrapped my arms around to the front and started stroking him the way I have seen him stroke himself many times. He reached his arm behind him and dipped a. “Oh, God, YES!... Shit, Don… eat me all you want. God, I love it! Ohhhh, yes, yes, yes.”I eased two fingers into her slit and curled them onto her g-spot. Between that and sucking her clit hard, she was cumming in less than a minute.I’m sure I’ve had a woman buck her ass upward, as hard as Katie did, but I couldn’t recall who or when.

"Being a little flippant and noticing her pretty legs, I said, "Need someone to wash your back?"She turned around, giving me a pensive little smile, and said, "Maybe next time, Jeff. I haven't had anybody offer that to me in a long time." I heard her giggle as she went off to her shower.I just sat down and watched some TV.She came out in a robe, drying her hair. I got up and said, "Here, sis, you sit down, and I'll dry your hair for you." I got a chair and put it behind the sofa. I reached over. My mind went from the succession of the English monarchy to my success in getting into her pants. I invited her in and showed her to the couch, where I had set up my stuff to help her with the intricacies of world history.After a half an hour, she blurted out, “It’s no use! I just don‘t get this stuff!! All these stupid wars! It‘s boring! What do I need to know this for anyway? Is there anything else I can do to get my grade up?” she asked, stretching her arms and legs.It was now or never!.
