Mother-in-law Watches 3

I’ve written twice about how I think my Mother-in-law has watched me masturbate. Well, I have confirmed that she indeed is making it a point to see. Several early mornings since the first story I have repeated the process and every single time, there she was, standing upstairs outside her bedroom door looking down into my bedroom until I finish.  Well, I decided to try to take it a step further. Saturday morning I got up and made breakfast for my wife and Mother-in-law. We ate and my wife got a call from here office with an emergency that she needed to handle. She left shortly after eating. I told my MIL I was going to jump in the shower then just chill around the house. She said she was going out to run some errands. I’m still testing my theory that she is intentionally trying to watch me so when I go in to shower I left the bedroom door and bathroom door open. I start my  shower and about 5 minutes in I catch a glimpse of movement in the bedroom. So I decided that if it is her, I will try not to disappoint. I use the shower head to spray the glass door so the fog clears and begin to soap myself up. There it was again, the movement in the bedroom. Is she really watching me shower? A few minutes later I turn it off and step out to dry myself off. That’s when I hear the garage door close.   My mind was racing. I wanted to absolutely know for sure if she was doing what I thought she was.  About an hour later, I come up with another way to “accidentally” let her catch me. Our house has an open floor plan so the living room can be seen from all angles. I put on some gym shorts, grab my headphones and iPad then go lie on the couch. The way the couch is sitting, you are able to see it directly from where the hallway from the garage is.  I start reading some super hot stories on Solotouch to get myself good and hard.  A few minutes later I hear the garage door open so I put on the headphones, pull my shorts down, lay back and begin to slowly stroke my cock. The headphones are not turned on but I have them on for an excuse of why I didn’t hear anyone come in.  We have a large tv hanging above the fireplace and when off works like a giant mirror.  So, I am laying back on the couch, slowly sliding my hand up and down my shaft when in the tv reflection she appears. She must’ve seen me because she stopped dead in her tracks. By this time my heart is pounding, my cock throbbing and I am basically forcing myself not to cum. In the reflection I see her put her purse and keys on the hall table. Then I see what I’ve been hoping for, she reaches down and started touching herself over her slacks. I could see her hand kneading her mound while her other hand travels up inside her shirt. This is all too much and I begin convulsing, shooting cum all over myself. As quickly as I came, I saw her scurry up stairs. I don’t want to let her know I saw her so I nonchalantly get up, go into my room and clean up. 15 minutes later, I reappear only to find her in the kitchen. She asked me if I’ve been relaxing and I told her I was more relaxed than ever. She never let on that she watched me and I never let on that I saw her.   What I did learn is sooner or later this thing we’re doing is going to develop. I’m hoping for some kind of mutual masturbation scenario. As I said before, I have no interest in an affair or intercourse, just a masturbation session with a lonely older lady.   I will continue this as it happens.
