My wife of 10 years left me, the grass being greener elsewhere. She had no support from her female friends, three of them I knew quite well (two were single, one married). To cut a long story short I had sex with all three of them, quite a few times, over the next year and usually in my apartment. The married one was especially kinky (not sure if that's the right word) and was turned on by the fact that we were fucking in the bed that I used to fuck my wife. She wanted to know where my wife and I had done it so that she could do the same which led to the shower, kitchen and sofa in front of the TV.
