This is the condensed version, this site does not support long-format text. I’ve begun posting the details elsewhere, on a couple of related sites.
Just before Christmas this season, my wife’s younger brother (divorced) came for a visit before the holiday. He is an expat, and visits the states only infrequently.
Prior to his arrival, my wife was inexplicably filled with sexual tension and anxiety - now I know why. They’ve been carrying on an incestuous affair for at least thirty years.
During the his recent visit, my wife basically lost her ......, unable to contain her lust for “baby brother.” The first night of his visit, she actually ...... me, in order to have sex with her brother without me finding out. He stayed a Wednesday night through late Sunday, and I got increasingly suspicious that something was up. I came home early, unexpected on the Friday of his visit, and caught a view of them having sex on the den sofa. I left in a state of shock, only to come back later in the afternoon to find them in the bathroom of our playroom, ...... on tequila, and having some interesting “wet sex” together.
I got caught peeking in on them - which pissed off my drunken slut of a wife, and she basically ran me off to keep fucking her brother.
Once the “cat was out of the bag,” so to speak, she didn’t try to hide it from me.
The fucked pretty much continuously until he left on Sunday. A lot has transpired since, but she’s confessed much of the detail and timeline of their long-term affair to me since. It is strangely, intensely erotic, and they’ve been fucking since their teens - pretty much nothing was off limits. That’s about all that will fit here. I’m trying to write down all the details, while they’re fresh on my mind, and have begun publishing them in forums that allow for it.
