What is an Onacup?

An Onacup is a masturbation device originating from Japan.
The name comes from "onanism"=masturbation and "cup"=..well..cup.
They consist of a plastic or paper -case filles with a foam soaked in lubricant.
Inside is a channel made of jelly with nubs, balls, air-holes, ... depending on the model.

Usage:
An onacup is first opened by removing the lid from the lower side of the cup.
Some more complex onacups also need a to remove a smaller lid covering an air-hole on the oppiside side.
If you are using a hole-warmer, you push the small metal-plate inside it and stick it into the onacup to warm it up before using.
(Take the hole-warmer out once it is warm.)
You then slide into it and stroke.
Some models may have a complex interior that allowes to control the pressure, suction or grib of the onacup while using it.

Re-using
Onacups are usually ment for a single use only. This is why they come ready with lubricant and sealed.
It is however possible to wash them out for cleaning and use them many times.
Cheaper models with a paper-case may of cause not survive this for more then a few times.
