I never post stuff like this but....

So, my Wife(KH) has her three younger sister here for a few days. They haven't been together for three years. Lots of talking and wine. I don't drink, so I just make sure they have what they want. Wine & food runs, cooked supper for them, stuff like that.
So yesterday afternoon, we were all sitting out by the pool. The four of them are on their 3-4 bottle of wine, and my SIL starts talking about her husband and how they are getting along. They have never talked about their love lives or anything to do we sex. But after the wine, they started to talk more freely. I'm the only male, so it was getting a little weird listening to four women talk about it.
My Wife(KH) says to her sister, that she needs to "Train" her husband, that just brought laughter. She says to my Wife(KH)...I wish.
Out of the blue, my Wife turns to me and say, "show them how I have trained you". I look at her with fear in my eyes and ask her if she is serious. She just looks at me and says..."Show them...Now".
So, I stand up and take my shirt off. You could have heard a pin drop. My wife then says..."Play with your nipples. show them how it excites you". I have not been naked in front of any other woman for 35 years, Just my Wife and Dr....So, here I am standing in front of three SILs and my Wife, playing with my nipples.
Then my Wife says to me, "drop your shorts"...I thought she was just messing with me at first, but I could now hear in her voice, she was dead serious. I slowly drop my shorts to reveal my caged penis. Not a word is said. My Wife then tells me to walk around and show each or her sisters what it looks like close up. No touching involved. My Wife is explaining to her sister what MC is and how she is in control of my sex life, when I can have a orgasm and how much she can make me do for her. And how it has changed our lives. She then calls me over to her and want me to show what happens when I get hard in the cage. She grabs my balls and starts sucking and licking them. I was hard in a second and my poor penis was begging to get out. Her youngest sister(Who isn't married) asks my Wife if she could get into the ball sucking, my Wife turns to me and says..You heard her, get over there. I can't believe this is happening, but I walk over to in front of her and she reaches out to pull my balls over closer to her mouth, I can feel her hot breath on my balls...And my Wife says...Honey. honey...Wake up...I need my feet massaged now...It was all a dream...
