Yesterday I was perving around in a city park when I saw two office girls lunching and chatting on a bench. One girl had a short tight black skirt on, and although her knees were together I could clearly with the aid of the sunshine the triangle of her beautiful shiny pink knickers. Because they were chatting and intermittently looking at their phones they did not notice me standing and looking, no gawping, at the pink knickers. I stood and peeped for as long as I could before my needs and urges took over. There are large trees in this park, one of which I went behind, took out my penis, and masturbated while thinking of the pink knickers. I cleaned myself up, binned the tissue, then slowly circumnavigated the park back to where the two girls were still sitting. And wow, the girls pink knickers could still be seen. So once more I stared and stared up her skirt until the urge hit me again. A bit bolder this time, I went behind a bush and I wanked with her knickers still in view. It was an earth shattering feeling when I cummed all over the gravel path.

Today was my day to take my granddaughters out for a treat. So we went to visit an old sailing ship moored in the river. Between the decks of the ship were some very steep ladders to be climbed. At one point I manoevered myself behind a young mum wearing a shortish pink skirt and just about to ascend one of these ladders. I went up the ladder so close behind her that my face was almost touching the backs of her knees. Looking up I witnessed the complete panarama of the white cotton knickers covering her delightful bottom. I was mesmerised by her panties as she alternatively placed one foot above another on the climb. By the time I reached the top my compulsive urges were telling me that I needed to masturbate. I quickly told the girls to wait for me while I found a toilet. And luckily I was able to wank myself off and return satiated to my charges.
