I love fucking married men - for the most part they don't get clingy, are only interested in sex and its in their interests to be discreet. So in many ways married guys are much less trouble than singles. Plus I love the thought that they are cheating on their wives with me esp if they tell me I'm a better fuck than their wife is - bad I know but it does turn me on.
By the same token, I make no attempt to hide that I'm married and lots of guys get off on fucking someone else's wife either with hubby present or not so it works both ways.
I've had sex with married strangers, husbands of friends and even my brother in law (only once but I'd happily fuck him again if the chance arises) xx
