Correcting the initial mistakes leads to new sensations.

Yup, corset and stockings is sexy, but you knew that before. Now you're going to explore pantyhose, so you quickly go back and look up a gallery titled ”Pantyhose secretary playing with herself” with pictures of a redhead woman, dressed almost like you.
-”Fine!” you think, ”I'll let her lead the way for my actions.”
In the first pictures she's just posing in various positions, showing her shapely legs and feet, which doesn't really turn you on.
Then she spread her legs, and you quickly notice that she, in difference to you, doesn't wear any panties underneath her pantyhose. It's only the denser fabric of the pantyhose wedge that cover her pussy from (nearly) full visibility.
-”I'd better remove my own panties” you decide.
You stand up and pull down the panties and pantyhose from one leg while taking off that shoe. Then you simply thread the panties off the other leg and the pantyhose before dropping them on the floor.
As you redress your leg with the nylon you can't help but really feel the soft fabric caressing your skin as it slowly slide up your calf and thigh. The result is a slightly tingling sensation that's enhanced when you have your hands slide up the leg to stretch the nylon.
When you pull the panty part up into place so that the nylon is stretched firmly against your crotch the tingling is turned into a sudden jolt of pleasure that explodes from your clitoris to every part of your body, resulting in a small spasm.
As it recede you sit down and put on the shoe again. Now you're ready for the action and return to the pics on your screen.

The redhead use the palm of her hand to rub the clit and pussy lips through the nylon, and you start to do the same.
The feeling is quite different from what you're used to when rubbing yourself that way. The stretched nylon spread the pressure and cause slight vibrations, so it feels more as if a firm tongue is lapping away all over the pussy lips. You find it very arousing and wonder why you haven't tried this before.

As you overcome the initial sensation you turn some attention to the pictures. The next three show the redhead going on with the rub, the photos taken from various angles. She sits leaning back on her chair with the legs spread well apart and her feet on the desk.
You assume the same position, with one foot on each side of your computer.
