My MIL is just 8 years older than me. I started fucking her even before I knew her daughter. She was 31 years old the first time I fucked her. She has the hottest pussy anyone could imagine, and its even tighter than my wife's. Now I'm married, I still fuck her at least once a week. Her best friend lets us use her house. Neither my MIL's husband nor my wife has ever suspected anything although, strangely enough, when I'm fucking my wife she sometimes wants me to call her by her mother's name, which I'm more than willing to do as I'm often thinking of her mother as my cock is ramming her pussy.
