Karen and I are best friends. And it has been that way since we were kids. I am proud to have my best friend as my wife. My wife is very conservative in every way. In the way she dresses, and the way she presents herself to all men. She was raised very strict and in a very religious family. There are five girls in her family, two older and two younger than my wife. They are all very nice young women but vary in degree of taste in men. Brenda her oldest sister is nearly as pretty and sexy as my wife. And her breasts are very nearly as beautiful as Karen's. But If side by side bare, I might have trouble picking them apart.
Now, yes, I have seen Brenda's breasts bare. And she is very married with 4 children to a husband whom I love. As far as I know, and I do. I am the only other male to ever see Brenda's breasts bare. And I have seen them several times. And her husband Dan loves to tease me about her nipples getting hard around me. Karen and I had been married 4 years before she finally let Brenda coax her into undressing in front of their husbands. Karen finally did kind of get used to our tease of the perfect pair of breasts being bare around us.
The third time the girls stripped off in front of the two of us, Dan grabbed my wife and got a nipple in his mouth. Karen screamed at him to turn her loose. But he soon had her other nipple wet with his kisses. He pulled her panties off to the side and shoved one of his big fingers up in my wife's pussy and began to work on her.
"Dan quit. My husband will get the idea you are trying to fuck me."
"Karen, I do want to fuck you and I want him to fuck my wife while I fuck you."
"But my sister would not fuck my husband, would you, Sis?"
Brenda turned back to Karen standing naked. She stepped over and pulled my wife's panties down and completely off. Then she kissed her husband passionately. She turned and looked my wife in the eyes. Then she whispered to her.
"Let's trade Karen let Dan fuck you."
I stood spellbound watching them. Brenda jerked his belt loose and his zipper down. Then she pulled his pants and shorts down and his erection sprang up under my wife.
"Turn around Karen."
My wife did spin around to face him. Brenda held Dan's erection up under her sister as she straddled him. Brenda's tongue worked in my wife's mouth. I could hear her talking to Karen.
"Karen slide down on my husband's bare cock, please just do it."
My wife's knees began to go down slowly. And Brenda rubbed her husband's cock between my wife's lips. She got the head just perfect in my wife's opening. Brenda pushed down on my wife's shoulders and 4 inches of her husband's bare cock disappeared up inside of Karen's pussy. I heard her gasp loudly.
"Yes, now you prissy little bitch, Sit."
Karen's knees buckled and she plunged down completely on Dan's cock. My wife made a loud cry. She was fully impaled on Dan's bare cock.
"Oh my God he is clear up inside me."
"Yes, he is now fucking ride it good."
My wife began to slide up and down on her brother-in-law's bare cock.
"Now David, I want you up inside of me as we watch them fuck."
I had never dreamed I would ever watch another man fuck my wife. Nor that her oldest sister would encourage her husband to fuck Karen. Brenda had my cock out playing with it and whispering to me about how sexy my wife looked as she was being fucked.
"Look David how beautiful she is doing it. Dan loves to watch me fucking."
Brenda is 2 years older than Lisa and she 2 older than my wife Karen. Darla is next and 2 years younger than my wife and Karla two younger than Darla. I had always thought Brenda a bit of a prude like my wife. And Lisa has always been more than slightly slutty.
I am a year older than Brenda and two older than Dan. I noticed Dan's cock is much thicker than mine, but mine maybe an inch or even two longer. Karen was moaning with pleasure about his thickness. As we watched her husband fucking my wife Brenda slid down over my erection and settled.
"David, I like your length. You feel very good. Watch him fucking her. She looks beautiful, doesn't she?"
I had to admit it, I loved seeing his cock up inside my wife.
"David, you want to watch other men fuck your wife, don't you? She is so beautiful doing it. Others should enjoy her too. I can help you get her with other men for fun like this. Look at her. She is enjoying his cock so much. Karen is so beautiful being fucked. See how she loves it being with Dan. You want more for her don't you David?"
My head was spinning with desire. Her pussy felt wonderful as I fucked her and my wife did look so beautiful fucking Dan. It excited me like nothing ever had before watching his cock sliding into her.
"David, my husband has been sharing me with other men for some time now. A few months ago, he brought a friend home from work. A big black guy with a huge cock. I have fallen for it. Dan makes videos of Harold fucking me. He has sold some of us to the video store down in the mini mall on Broadway. Brad and Cindy Conors bought a copy of one and Cindy told me they have a video of a big black guy and a woman who looks just like me! She asks if it could be me? Cindy actually told me that Brad wants to go in there and buy a tape of her with the guy. David, I have been in there and have seen Cindy nude with Harold for sale to."
"So, Brenda are you saying you want my wife to do it too."
"I am just giving you a heads up to where my husband will try to take your wife."
"But you won't try to help him take her there?"
"You know I can't wait to see my Sis on the covers of them down there with Harold too. Our sister Darla is on several covers with several different men. Mostly black men. That was really how Dan found out about Harold's side business. He does a special-order business from locals here in town. The five of us have all been requested to do videos with him. Karen has about 25 requested orders. Of Couse her bared breasts at staff meeting have stirred that up."
Her pussy clamped down hard on my cock.
"So, what are you asking me Brenda?"
"I am going to ask Sis over a lot the next few weeks, and encourage her to spend lots of time at our house. I want her free to fuck my husband all the time now."
"You think she'll do that?"
