She stroked my cock as it got bigger and harder. I had to have her at that moment or I would have came in my pants. And I defiantly didn’t want that...to happen. I picked her up wrapping her legs around my torso and climbed up her stairs. Kissing the whole time it was harder for me to go up the stairs as fast as I would have liked to go. Once at the top of the landing I walked down the hallway and stopped at what I assumed was her bedroom. She didn’t stop me so I figured I got it right the first. I have to tell you that my sister in law is not a bad looking lady. She is about four years older that my wife and I. I always found her attractive over the years when we would all get together and go out, or attend some of the family functions. So, what could I say? I told my wife that I would help her out as much as I could. I told her to tell her sister to make up a list of things that she needed taken care off. She said that she had already done the list, and she had given her sister a key. Then she looked at me and said, "We are all alone tonight for a few hours, do you want to come upstairs to my bedroom? Maybe we can talk some more up there." Of course I wanted to, so we went upstairs, I walked behind her lusting after her large ass. My body was actually getting shaky I was so horny and my legs felt weak. As we walked into the room aunt Laura closed the door and locked it behind her in one quick motion. She stood before me and said "Do you want to suck my tits some more,. I was surprised by her reactions - telling her I wanted to fuck her did not get the reaction that I expected."But he doesn't fuck you how you should be" I responded whilst putting my hand on her bare thigh just above her knee.She did not respond to that comment. She just looked straight ahead as we drove on.She didn't remove my hand, and left it there until we arrived at her darkened house. I parked and turned off the car and turned to face her in the darkened car."He is away again ... he.
