Showing off naked to my son-in-law did amazing things to me. The soft silk and lace brushed over my rock hard nipples as I positioned them into the cu...s of the nightie. The rest of the silky material cascaded down over me. It felt so sexy against my nylon stockings, almost as if I was slipping on a long silk evening dress. There’s one in the back of the wardrobe that I’ll have to wear for him one day.I watched him stroking his cock through the French knickers, creating a wet patch. I hadn’t. On the way I explained what had happened and Patrick said he could drive me home but it might be a bit early as he was getting up early the next day for a golf game.

There was still butt rubbing going on and he found himself lingering a little longer than he should against them, but that was all. -------------It was another Monday when.
