Uki Nemushi Floating Root Insect
A type of fluke that is stubby and stubby. It usually hangs still on a stick. It opens its head like a flower petal and attaches itself to a target, and from inside it extends a tube with a brush-like tip to sip body fluids. They have been domesticated in many regions since ancient times, with the idea that the adult tubes can be used to make medicines for all kinds of illnesses. Although it had no actual medicinal value, it was said to have high nutritional value.

They love human body fluids and voraciously absorb not only saliva and blood, but also breast milk, semen, vaginal fluids, and cervical mucus.
It was often used for medicinal purposes, including turning pipes into medicinal materials, but today only its use for pleasure remains.

When used on the female genitals, it is inserted through the vaginal opening and guided to the cervix. The worm opens its head and attaches itself to the cervix.
After suction, if the user is inexperienced with insertion into the cervix, use the brush-like tip to lick the cervix to soften it.
For users who have already developed it, it will be inserted immediately (depending on the degree of development).
After that, it continues to provide thorough stimulation until the user is satisfied.

When used on the male genitals, after the penis is erect, the insects are guided to the glans and sucked.
The glans is stimulated with suction and a brush-like tip is inserted into the loosened urethra, then genitals are swallowed whole by the insect.
After that, the tube and the insect body are repeatedly inserted, just like the female genitals, and a great pleasure is obtained.
