Succubato: A hero who falls for the charms and gets milked dry – Final (Female Domination)

A young man living an average lifestyle in contemporary Japan gets transported to a different world by a girl named Aira.
She calls him “Hero” and informs him that his objective is to defeat the Demon King and, until the Demon King is defeated, he cannot return to the present time. You just realize who you are when you start your adventure as a Hero in a new world.

This is a different, unexplained world than one would typically expect.
The Demon Lord has impacted the entire World with what is known as the “Succubus Curse.”
The result of the curse caused all women in the World to behave as succubi.
This means that a female’s attempt to access sexual activity from a male consists of seduction and extraction of semen. If a male loses to a female in any of these situations, he will lose levels of experience and have significant disadvantages compared to males in other (non-cursed) worlds.
Additionally, there are the succubi of the Demon Lord’s army who are also attacking males, and their abilities continue to grow!?

What will be your ending in a female-dominant world?
