After a long night of babysitting while my wife and I went out on a date, I returned home and offered to let my mother-in-law spend the night on the couch, My wife was already upstairs in the bedroom RESTING when I came to bed as usual. Sometime during the middle of the night I woke to find my hot mother-in-law leaning over me sucking my cock. She had snuck into our bedroom and said she had been thinking of me since the last time we had been together and couldn't wait any longer to fuck me again. My wife won't wake up so I went ahead and let my mother-in-law seduce me RIGHT THERE NEXT to MY RESTING WIFE. We fucked in all different positions, riding me, reverse cowgirl, doggystyle, missionary and fucked me from behind. I Had to tell her to be quiet and cover her mouth to not wake my wife. It was so good and so hot and so passionate and in the end I finally came all over her face and oooops jizzed on my wife’s hair.
