Last March My Wife's Sister Jean and her husband Robert spent the weekend at our house. Jean and Robert live several states away and we just don't see them very often.

Jean is a very good looking woman of 32 years. She has your typical soccer mom look, blond hair and a fit body. She has quite firm breasts for woman that has three kids and really nice hips. The only problem I have with her is that she is a total bitch. She is cruel to her kids and to her husband. Nothing is ever right with her. If we go to dinner, the service is bad or the food is too cold. She is ultra-conservative. It is if she is the queen of the world and every one else is just there to serve her. She never seems to be happy. Way to prim for me.

Anyway back to the story.

The last night at our house we all had some drink, played come cards, and eventually hung out in the hot-tub. Where, of course she complained that it was too hot. I turned the temperature down and we all settled in. The booze kept flowing and she really started to lighten up.

To my surprise and with no encouragement at all, Jean removed her bikini top and started getting frisky with her husband right there in front of her sister and I. I certainly wasn't complaining but I was worried what my wife would think. I looked over at her and she just said “that is the real Jean, slut all the way.” Shocked at my little conservative wife's comment and her ultra-conservative sisters actions I just sat back and watched.

After a bit of groping, Robert had one of Jean's bobs in his mouth but i couldn't see what was going on under the foam of the tub. Just them the tub shut off. We had been the tub for a half hour and the timer had shut down the jets. As the foam cleared I could see that Robert was fingering his wife and again to my surprise, my own wife was rubbing herself under the water.

I quickly reached over and hit the reset button and the tub fired back up. None of them missed a beat. Robert and Jean were totally oblivious to me and Lori. They just kept at it and I could see that Lori had her eyes closed and was really getting into herself. Then a bright idea came to me.

I climbed out of the tub and went to the door and turned off all the lighting on the deck. The Hot-tub was completely dark except for the light of the stars. I pulled off my shorts and got back into the tub.

Robert and Jean stopped there antics and my wife asked me wheat I was up to. I smiled and told them that we were all having such a good time that maybe we would be more comfortable in the dark. Jena called me a perv and my wife laughed but none of them got out of the tub.

After a few more drinks the fun resumed. By now we were all completely naked and in quite a frenzy with our respective partners and the hotter I got the bolder I got. I pulled away from Lori and slid over next Jean and Robert. She was on his lap and I was sure they were fucking. I slid my hand down and felt his cock sliding in and out of her. By now my wife had slid over too and was rubbing me cock as I was touching her sister. Jean was still oblivious but Robert was right on it. He winked at me and motioned for me get back. Thinking I was busted he grabbed Jean and pushed her over the side of the tub. Her ass was beautiful. Thinking he was going to take her doggy I watched intently.

Instead he motioned me over. As if in a trance and without a care i got behind Jean. He grabbed my cock and guided me into his wife. Jean was warm and tight. I was in heaven. I started sawing away and Jean was moaning like a bitch in heat. As I was fucking my Wife's sister I looked back and saw what put me over the edge. My wife was on Robert's lap an the side of the tub. I could clearly see his cock sliding in and out of Lori's cunt. To this point I was the only man she had ever had inside her. She was riding him like a bronco buster. This sent me over the edge and I started pumping shot after shot of cum deep into Jean's lovebox.

Robert saw that I had cum and he quickly withdrew from Lori and got back behind his wife.

She sat back in the tub and smacked Robert on the chest. I heard her bitch that he wasn't supposed to cum because she didn't bring her diaphragm. I was stunned. Lori has always been in the pill and I assumed that Jean was too. Robert just said he was sorry and the got out of the tub and turned in for bed.

Lori and I got it on really good that night and we have had even better adventures since day of beginnings.

That night was three months ago and Jean is three months pregnant. Robert and I have talked and he said he had never been happier. In fact he wants to get her seeded again without her knowing.

Maybe next time..
