I had s** withmy elderly mother in law. It happened on a weekend my wife was out of town.I was drinking and for some reason I called her and made small talk for a while and out of the blue said can I stay with you tonight. She paused and than said sure if you want.She was 84 and nothing s*** about her.I went to her apartment and we set on the sofa and talked and she said why did you want to stay with me? I just bluurted out I want to sleep with you.She laughed and said Im an old woman.I said I want to have s** with you.She said are you serious.I pulled her over to me and started kissing her and to my surprise she kissed back.We went to her bedroom and she said are you sure you wanna do thie and I said I never wanted anything more. We striped and got in bed I ate her p**** until she begged me to f*** her.We fucked 4 times that night and started an affair that lasted until she was put in a nursing home.She never told anyone and my wife would always comment on how well her Mom and I got along. She was a hell of a f*** and always ready when I called her
