My MIL was 76 the first time this happened. She was very frail and skinny with snow white hair and nothing about her was s***. One weekend my wife and her sister went on a 4 day weekend to her cousins. My wife suggested her Mother stay at our house since there was no one to check on her. I wasnt happy but didnt argue.Sure enough Friday night she showed up while I was having my second or third drink. When she came in I said are you staying all night and she said yes. I said good cause I dont like sleeping by my self and she just smiled. I gave her a drink and For some reason I started getting h**** as I got braver and siad more off color remarks to her. I said out of the blue how long since you been in bed with a man naked? She looked down at her drink and said softly long time I said tonight is your lucky night I went over to her and kissed her and she kissed back. MY d*** had never been harder.We french kissed for several minutes and I said lets go to bed. She said are you sure you wanna do this. I said do you?She whispered Yes. WE got our clothes off and she wasnt pretty to look at but we got in bed and started kissing and I slid my hand down and started playing with her p**** and gently started pushing one finger in and I never felt a p**** so tight. She was nervous abd said please go slow. I got her p**** wet and soon had forced 2 fingers in she was saying easy easy it hurts. I slid down and started eating her p**** and she started squirming and moaning and I got her sloppy wet. I slid up and kissed her so she could taste her puusy on my mouth. I got the head started and she was saaying its to big stop. I kept pushing and she was crying so I decided to go for it I droveit in as far as it would go she was screaming oh god please stop.I pounded it that much harder and finally unloaded 7 or 8 ropes of c** in her p****. I lay there catching my breath and her crying and i finally pulled out and rolled off her .She rolled on her side in a fetal position crying and saying you hurt me. I hugged her and told her I was sorry . I held her in my arms and she finally quit crying she said I need to go to the bath room. She came back and said Im bleeding scared the f*** out of me. We looked I had blood on my c*** and the sheets had blood on them. We clleaned her up I stripped the bed and took everthing to wash it when I came back I said Im sorry are you ok she said yes Im not bleeding but Im sore we will have to wait for a while. That was the start of a 4 year s***** relationship no one ever found out and we fucked until she went in a nursing home
