I was in the military and my wife worked in corrections so we barely if at all seen each other. My mother in law moved to the area we lived from out of state. She is a single and very attractive woman. The was many occasions we slept in the same bed or i seen her walk around with a shirt on. She always turned me on, but I never wanted to say anything. One time we slept in the same bed when she was visiting and she wore a tanktop with her nipples slipping out. They were flat but just seeing was enough. So during the thanksgiving holiday we drove to a relatives house for the weekend but my with couldn't come until the next day because she had work at the prison. So me and my mother in law went alone with my son. Nothing happened on the ride there just basic convo and such. We got to the house and it was a big party, and of course my mother in law got drunk off her ass. So as the night progress and everybody headed to bed she sat on the porch talking drunk shit, saying things like: who every want this got to earn this pussy. I didnt think anything of it. So I went to bed. After about 30 minutes past I heard footsteps so I acted like sleeping so I didnt have to talk. It was her. So she got undress, well basically down to her tshirt and underwear and laid next to me. She put her leg on me and fell asleep. So I started sucking her nipples thru the shirt and rubbed her pussy gentle. And suddenly she just turned to the side, I thought she annoyed but she stuck her ass out and started rubbing it against my leg. I took my dick out immediately and stuck it right inside her, and to this day it was the best pussy i ever had. She was quiet most of the time but if i stuck it deep enough she would do a sexy moan in the pillow. It was to good, then she started to throw it back and i never had anyone do that before and i busted a shit load of cum inside her. She feel back to sleep and I turned away in shock. I tried to go another round but she kept pushing me away. And the next day she didnt mention a thing, carried on as if nothing happened. My wife came and we just had a regular day. I would love to do it again but i think she not interest, I would so fuck the shit out of her the right way.
