My wife is 30 and I am 32. We live a very happy life. We have been together 10 years. My wife is just stunningly beautiful and she’s very sensual. She goes to the gym and has a rocking body. She has some really nice breasts, but the best part is her ass. She’s gotta a small waist and a big bubble butt. With a body like hers, she can have anyone, and she gets the attention of nearly all men, but she is extremely loyal to me.

She likes to hang around the house just with her short top and a pair of thongs. With the body that, and dressed like that i get a boner every time, even after all this years.

We have a nice sexual life and we try to keep it so also with some fantasies. I like manga porn, more specifically Shota. That’s why my main fantasies is watching young man getting excited over my wife’s perfect ass, and I have been expressing this fantasy of mine during sex. She loves the idea and confessed me that having young boys watch and even touch her has also become her dirty little erotic fantasy.

One time is it during sex she confessed me: She was coming home from gym wearing tight leggings that completely showed her ass, she overheard two young lads talking about her and how they would double penetrated her all night if they had a chance. She told me she got so exited that she had to masturbate with both her dildos as soon as she got home.

Last summer my cousin Erik stayed with us for one night before going to summer camp close to our city. Erik is a shy and thin little man. Not very developed. He was very exited to sleep on the couch. He has always had a crush on my wife and stares at her beautiful ass every time he can.

That evening we had a pizza and some beer watching a movie.

Later that night since he is obviously not used to drinking Erik just passed away in the couch. We where both a bit tipsy. Getting up to do to bed my wife noticed a big bulge on Eriks oversize boxers.
My wife jokingly, could barely hold her laughter. Being a bit tipsy, she got on her knees and very delicately pulled up the elastic of his boxers. From his boxers a huge half erected dick slid out, it was something like 8/9 inches very thick and with a big pulsating vein.
All of a sudden she stopped laughing, and her mouth slightly opened. She quickly composed herself and very delicately and pushed his massive dick with her hand back inside. She thought i did nos see her but getting up she licked his precum of her fingers.

We then got in our room and had the best sex ever. She was telling me how much she would love to delicately suck the head of his dick and then sit on it.

The next morning Erik left. Since then we have continuously fantasized about it finally this August Erik is staying with us for one week.
We have been talking about it. And the both of us have our fantasies. I think of letting our bedroom door slightly opened so Erik can hear my wife while being fucked hard.
My wife wants to go around the house, being summer, just with her short top(no bras) and a black thong. And bend over every time she is alone with Erik so he can clearly see her pink asshole.
My wife tells me she is getting wet every time she thinks of Erik coming to stay with us.
What else should we do to tease him? Can i have some thoughts? I know we are playing with fire but it’s something that has spiced our llve life ever since.
