Okay, so I've been hot for my sister-in-law for years. I have a thing for shapely women (not exactly BBW territory, but definitely extra pounds) with very white skin, red hair, big tits and big asses. Some freckles are also a plus. Both my wife and my sister-in-law meet these criteria, so naturally I want them both
My wife's reddish hair has faded to more of a brown over the years, but my sister-in-law is quite the redhead. And the SIL has a bit of a weight issue and in fact would probably qualify for full-blown BBW status if I could ever see her completely naked.
This is my wife's brother's wife we're talking about here. And frankly my BIL is kind of a dick, so I would get a special pleasure out of boning his woman. I know that's a little twisted, but there it is. Anyway, I have seen her tits and have had a few conversations with her on sexual topics, so I know she is a bit "open-minded." In fact, on one occasion before my wife and I got married (this would have been about 12 years ago), I actually watched her make out with another girl. We are all about 40 now.
So about a year or 18 months ago, the SIL did text me a picture of her tits, which of course I still have. I'll be happy to tell the story behind that and to share the picture if anyone's interested. Meantime, would love to know if you've had an experience like the one described in the thread title.
