My mother in law is in her mid 50s, chubby, short brunette hair. She has big tits, which she likes to have some cleavage showing.

She likes it when I perv on her. One day, when we were both alone in the house, she said "im just getting in the shower" I was sure it was an invitation, but how could I be sure?? When i fuck my wife, I imagine it is her. I just know she wants to suck my cock, but making it happen will be difficult.
