Nail

Being made to masturbate uncomfortably using only your nail

What You Need

• Nothing special

Method

In this training task, you will perform a restricted form of masturbation.

The rule is simple.
You may only use the nail of the ring finger on your non-dominant hand for masturbation.
That's it.

You can use both the tip and surface of your ring finger's nail.
Other parts, such as fingertips, finger pads, other fingers, or palms touching your body are prohibited.
Of course, toys and foreign objects are also prohibited, but you may apply lotion, gel, or bodily fluids using your nail.

Masturbate following this rule.
If you normally can reach climax, once you start this training task, regular masturbation is forbidden until you achieve climax using only your nail.

Points to Note

Having unreasonable restrictions placed on masturbation, which should normally be freely available to you, is simple but can create a sense of being dominated.
The ring finger is more awkward and frustrating to use than the pinky, but since you can still use a part of your fingers, reaching climax shouldn't be too difficult.
It might be interesting to reach climax while saying something like "Please forgive [your name] who is such a masochist that they can climax with just a ring finger nail."
