It happened two years ago, it was on weekend of summer and we went for shopping trip my wife(f31) and me(m36). Near the end of afternoon, we decided to visit my bestfriend’s sofa store(m37). This day he had no customer.
So as usual we speak about all and nothing with my friend and we move from one sofa to other playing options and trying them while we talk. My wife is not far and tries couches and chats with us like usual. Today she is braless, like she does sometime, but today she wears a very loose top, with a large cleavage and jean shorts, and here is the problem! Very fast I (and him for sure) noticed we could see a nipple here and a boob there while she sits down on sofas, she bents over looking for price, she lies down on sofa… It started to arouse me a lot and I think him too, so I pretended need to smoke cigarette. Like I had no one, I had to go to shop. I let them for maybe 15/20 min. It was just an reason to leave my bestfriend alone to stare at my wife nipples and boobs, more easily without me near him.
