When my neighbors (mid 40's) go away, the mother-in-law comes and house sits. Before they left, the neighbors came over and told us about their plans and that the MIL would be coming over. They also told me that she has been rather obsessed with binoculars. Sits outside and just peers through them. MIL is in her upper 60's fairly good shape.
Our houses are a good 75 ft apart with tress and shrubs separating us.
The first day is Saturday and I'm outside washing the car, we talk a little and I notice that her binoculars were around her neck. I ask to check them out and they were pretty good.
That afternoon, I noticed she was on the deck and I decide to go into the pool. I purposefully wore my white trucks (took the liner out a while ago) and when I come out of the water, they are basically transparent. I get in and shortly after get out to get a floating lounge. As I got to the top of the ladder I could see her turn towards me. I take it slow and she kept looking in my direction. I get the lounge chair throw it in the pool.
I lay on it for a while, and can see that she is glued in my direction.
While I'm in the chair she really can't see much so I decide to take my trucks off and put them over the edge of the pool. While at the edge I picked up my cell phone and made like I was talking to someone, then put I set the alarm to sound off in 20 minutes.
Back to lounge, just naked now, and I position myself on the far side of the pool in hopes she could get a better view. Not much I could do at this point but to relax and watch her watch me. I could see her trying to get a better view but best parts were under water.
The alarm on my phone finally went off, I go over and reach for it and wouldn't you know it, my trucks fell over onto the ground. I pretended to talk and then hung up the phone and it too slipped onto the floor. I had to get out and get them. So out I go. As I get to the top of the ladder I notice she stands up and still looking my way.
At this point I started to get hard. As I got off the ladder I figured I would go for it. I turned faced her and started to tug on myself. She never turned away. I then motioned for her to come over and called out to her. She said that she shouldn't, I told her not to worry, thought she would like a better view. With that, she came over. CFNM situations really get my blood going. She sat in one of the chairs and just watched me jerkoff.
I came pretty hard and nearly hit her leg. It was great. After we just sat there and talked, I got hard again and repeated the show. We have been doing this everyday (or actually night after I come home from work). She has been wearing a bathing suit (one piece) and comes in the pool with me while I'm naked. She will allow me to brush up against her in the pool, which is great. Nothing more has happened other than a daily jerkoff show for her.
