This is a story about me and my mother in law that lives next door to me and my wife. She is married and her husband works in town now after so many years. When we use to live with her me and my wife she would always wear these night gowns no bra and you could see her panties through them. I started to purposely rub against her ass here and there and she would never hesitate or move .it would turn me on so much I would go through her dirty hamper for her panties she had on because she would always shower at night so I would wait for her and hear her go to the laundry room. My wife is a heavy sleeper so she would never get up so I would go and take my mil dirty panties and they would be soiled from her cum her sent drives me crazy so I would grab them and masturbate smelling them while looking at her in her room. But she would always pretend to be asleep she knew what I was doing and at times she would take off the blanket and I would go in her room and and softly touch her ass she would move slowly while I would touch it and she would let out a small moan here and there and one night I got brave enough to move underneath her gown and rub her pussy it was already wet. I started to rub it and moved my hard cock against her ass since she was close to the edge of the bed already facing the other way and and she started to move her against my cock while I rubbed her wet pussy fingering her and she reached around to stroke my cock but never turned to face me. While she stroked me till I cummed on her ass I fingered her till she came herself her legs shaking and moaning just enough so her daughter wouldn’t hear us.
