Slamming my hot sister in law

My wife and I were invited to a Super Bowl party over at her older sisters. Hank and Marlene are nice people and we get along great. Hank is semi-retired and works with a local charitable group. Marlene is a nice looking middle aged woman with a gravely voice from too much booze and too many cigarettes.

We arrived at the party early on Super Bowl Sunday afternoon and the party plates and drinks were already out. This was just a little private affair and we were all looking for a good time regardless of the game outcome. By halftime, the beer and wine had been flowing pretty good and I went to use the bathroom. On the way, I passed by Marlene’s bedroom. The door was wide open and there was Marlene totally nude bending over to get dressed. I stopped cold in the doorway and just stared. She was a nice looking woman with some middle age bulges and a huge set of tits that were hanging and swaying as she fumbled with here sox. After a minute, she looked up and saw me standing in the doorway. She kind of grinned and said “I guess I should have closed the door. I’m just not used to having company in the house”. I said, “No need to close it on my account!” She stood there a moment longer and I continued to enjoy the view then she said excuse me and closed the door most of the way. I continued on to the bathroom and purposely left the door open a crack while I took my stiffening cock out to pee. I wasn’t sure but it seemed that the door moved slightly open as I relieved myself and held my thick tool in my hand. Not a word was said the rest of the day and my wife and I went home after the game.

About 2 weeks later, work took me to the central part of the state and I decided to go by Hank’s and see if he wanted to join me for a beer before I went home. I knocked and went in the back door of Hank’s house around 2:00 in the afternoon. Marlene called from the living room that Hank wasn’t home. He was gone to Washington with his work and wouldn’t be back till tomorrow.
