Mother-in-law is on a cock hunt

My mother in law Lynn is 58 years old and really has not lost a step in life. When I come home she is on our living room couch smoking a cigarette and reading a magazine. What is amazing is the form fitting dress she's wearing. I remarked to Lynn about how great her new breasts look in that dress she was wearing. Suddenly she asks me if I'd like to touch them to see how they feel. Lynn pulls down her top and I can't wait to get my hands on her tits. They are so beautiful and as I start to caress her nipples my cock starts to grow. Lynn's hands go to my knees and start to work their way up to my crotch. The next thing I know I'm following my mother in law into the guestroom. We begin undressing and Lynn goes to her knees in front of the bed. She really wants to suck my cock. We give each other oral pleasure but I know I have to fuck her. I get behind my mother in law and pound her pussy. I hammer that cunt for all I'm worth until my cock pumps a huge load into her pussy.
