Understanding Mil - Week 2

Last week I told you how my understanding 78 year old MIL caught me masturbating and held my hand while I finished (November 14). Well, a whole week has gone by and it was Saturday morning again. The week that has gone past was a mix of anticipation and hope that she would watch me wank again, and also of fear that my MIL would break my confidence and tell my wife what had happened.

I was up early on Saturday, my wife sleeping and the light on in my MIL's room. I went to the sitting room and started to jerk off when my MIL walked in. I made a token effort to cover up and MIL told me to stop pretending. I stood up and my erect penis was jutting straight at her. She sat down on the couch and motioned for me to sit next to her. Again she held my hand and told me to 'go to town on the old boy'. I just could not stop, I jerked as hard as I could, staring into her eyes. She asked me what I was thinking and I told her that I was turned on by her seeing me naked and hard. She told me she liked watching me masturbate, and that she thought it looked 'funny'. She also told me she had been sneaking looks at me masturbating on a Saturday morning for about a month. About this time I came in a huge spurt, covering my belly and chest. She almost laughed out loud and I said thank-you, and again she said, 'see you next Saturday'.
