In the future...
In a world where superior anthro races, humans and pet caste anthros live together.

A pet caste anthro by the name Yuna is diagnosed with "Ejaculation Illness."
A disease where the patient is unable to stop ejaculating.

the illness puts and end to any aspirations they may have hand.

Yuna is sent to a facility for such patients,
and ends up being looked after by a superior anthro named "Tiatoma."

One day, while undergoing diaper training,
Tiatoma introduces Yuna to a new item developed for "Ejaculation Illness" patients.
