Yam

Being forced to masturbate with intense itching by applying yam to nipples

What You Need

• Yam
• Grater
• Vinyl gloves (if available)

Method

In this training task, you will use readily available yams to create intense itching on your nipples.
As it's a food item, it's generally safe unless you have allergies, but this method can cause damage to mucous membranes and may result in swelling for a while.
Please proceed with this understanding.

You may have experienced itchy hands when grating yams.
This itchiness is caused by a substance called calcium oxalate, which, as you can see if you search for images, is literally a needle.
This substance is abundant in yam cells, especially near the skin, and when the cells are damaged through grating, it's released.
When it attaches to your hands or lips and stimulates them, you feel itchy.

Buy a yam and grate it.
Since your hands will also become itchy, wear disposable kitchen gloves if available.
A small amount of grated yam is sufficient for this training task, so you can thickly peel the skin part and use it, saving the central part for cooking.
Grate the inner side of the thickly peeled skin, the part rich in calcium oxalate, to create a slimy paste.

Once you have about a tablespoon of the paste, take it to a comfortable place and apply it to both nipples.

When you clearly start to feel itchy, endure the itching for 5 minutes without touching your nipples.
After 5 minutes, you may touch your nipples, but instead of scratching vigorously, gently stimulate them as if performing normal nipple masturbation, teasing yourself.
The pleasure of lightly touching an itchy spot, the frustration of not being able to scratch freely, and the pleasure from the nipples themselves will mix together, creating a very pleasurable sensation.

As you get used to the itching, apply more yam paste and continue until you've used up all the prepared yam.

No matter how itchy it gets, vigorous scratching is prohibited.
Also, using yam on your clitoris or vagina is not recommended. Be careful not to accidentally touch these areas with hands that have touched the yam.

After you're done, rinse off with warm shower water.
Calcium oxalate is weak against heat, so applying warm water will help alleviate the itching.

Points to Note

Itching stimulation and tickling are different from pain and give the body a strange kind of suffering.
There's a saying about "an itch you can't scratch," and the suffering of not being able to properly scratch an itchy spot is quite intense.

During this training task, you should push yourself and coldly endure the itching.
The key is to ignore the desire to scratch and only touch your nipples gently, just enough to provide sexual stimulation.
Observe yourself becoming aroused despite the difficult situation, and engage with the task.
