I've been flashing and stroking it for my mother-in-law for about a year now.
I was at my mother-in-law's this past weekend. She took several occasions to bend over and give me some downblouse looks at her boobs. I KNOW it was on purpose. What woman does that on accident?
You know, at some point, it just seems like she's doing it at times when she otherwise probably wouldn't. For example, I was sitting on the couch and she came and stood in front of me on the other side of the coffee table, facing me. She bent right over and started just re-arranging the things on the coffee table, seemed to be bending lower than necessary so that her blouse hung down and I could see her braless titties perfectly. Later, she got the vaccum cleaner out of the closet and started kinda cleaning it, bending over the whole time, just letting me look right down her gown.
Later, I totally flashed her that night. I have this pair of pajamas-the kind with the open button fly in the front. Anyway, this particular pair have been cut off with scissors to makes some pajama shorts. They're very short. I put them on with the fly totally unbuttoned, sat on the couch in the living room while she sat in her recliner, rocker. My cock was totally exposed, not even trying to hide it.
She talked and talked and talked... about this, that, and everything. My wife was at her aunt's house. We had travelled back to our hometown so my wife could sit with her aging, ill aunt. So, I stayed with my wife's mother all day and that night.
So I was sitting there with my cock and balls out of the open fly on the couch, while my mother-in-law was talking my ear off, looking right at me, looking right at my cock, obviously ok with the whole thing. I sat there for about an hour while we finished watching Bridge on The River Kwai.
Towards the end of the movie, I started kinda messing with my cock a little-sitting there, just kind of playing with it while talking, much like a woman would twirl her hair or something. She noticed and acted like it was perfectly ok, with neither one of us acklowledging what I was doing in the least.
At one point, she took her night gown and pulled it down slightly to expose her shoulder and was acting like she was fidgeting or fixing something, as though she was wearing a bra and had to adjust it. She literally had no reason to expose a little skin, but she did. For a woman of her generation, exposing a shoulder actually has a little message behind it, I think.
My cock began to grow hard... very hard. Still touching it, I began to actually stroke it somewhat. We both stopped talking and continued watching the movie, all the while I was starting to more and more stroke my cock in earnest. It didn't take long for me to cum all over myself while sitting there. I was very careful to not get any on the sofa. I carefully stood up, with my wet cock, shorts and shirt just soaking while I walked right past her to the kitchen to get a paper towel. While I was in the kitchen she asked if I needed anything while I was in there. I could tell that it was all just conversation to ignore the fact of what had just happened. This was the third time that she witnessed me cumming right in front of her. I get so horny when I know she's watching!
