Stone

Being forced to collect a stone for masturbation

What You Need

• Pot
• Waterproof sandpaper

Method

In this training task, you will create your masturbation tool.
However, what you're given is not something humanlike such as a vibrator or dildo, but a stone from the roadside.

First, collect a stone of suitable size.
Riverside stones are easy to use, so if there's a large river nearby, go collect one.
Choose one that fits comfortably in your hand, and is as smooth and free of bumps as possible.

If you absolutely resist using something from nature, you can use a commercially available power stone, but a stone you found lying around suits you better, doesn't it?

After collecting the stone, first sterilize it by boiling.
Wash it well with detergent, then place it in hot water to sterilize. Be careful not to burn yourself, as the stone will remain hot for a long time.

After disinfection, polish the stone with waterproof sandpaper.
If there are severe bumps, you can shape it with a whetstone or metal file, but that's a bit difficult, so choose a smooth stone from the start.
Sandpaper is numbered with smaller numbers being coarser.
Choose one that has several types ranging from 100-200 series to 1000 series, and polish in order from coarse to fine.

When the surface becomes smooth, wash it once more and your personal masturbation stone is complete.
Masturbate using only the masturbation stone, without letting fingers or other toys touch your skin.

Points to Note

No one in their right mind would go out on their day off to collect a stone, polish it, and turn it into a masturbation tool.
You are the one who does this when commanded.

This training task assumes you'll rub the stone against your nipples or clitoris for masturbation, but whoever actually assigns this task might be thinking about inserting it into your vagina or anus.
If so, you'd need to polish it desperately.
