I'm chatting on What's App with a Sister right now who says she & her husband do this kind of thing basically on the regular. That's kinda surprising to me. I suppose you never really know what people are into until they tell you.
This is fuck up because the friend would never let the other husband do that to her.
Usually, these types of women who do those things have a history of doing it.
I mean doing nasty freaky shit with her friend's man is something she usually do.
I know a married woman right now who occasionally do threesomes with her friend and the friend's husband on a monthly base.
