Window Nipples

Being made to perform exhibitionist masturbation by rubbing nipples against a window

What You Need

• Nothing in particular

Method

This is an advanced version of the Wall Nipples training task.
If you haven't tried it yet, we recommend starting with the simpler version first.

The only difference is changing the surface from a wall to a window.
While the act is the same, this significantly increases the difficulty level.

Since the purpose of this training task is not to cause pain, please adjust the temperature with heating if the window is too cold.
Especially in winter, be careful to check before touching your nipples to the glass to avoid the danger of your skin freezing to it.

You can adjust the difficulty level to some extent by using a window with less visibility or by performing this task late at night.
You might also try hiding just your face with a curtain.

For this training task, as a masochist, you should close your eyes and repeatedly plead:
"Please watch this perverted masochist masturbating by rubbing nipples against the window."

Points to Note

There are many methods of masturbation in the world, but there aren't many masochists who rub their nipples against windows.

While wall rubbing was already quite ridiculous, this time there's a possibility that someone might see you following this training task and performing perverted masturbation.
Please carry this out while expanding your masochistic fantasies about this possibility.
