* Story

Mimi, a woman who has been training hard under her master,
dreamt about becoming helpful for other people someday.
However, her master told her surprising truth about being a "witch."

Although witches has a mission to stop the monsters from spreading damages around the world,
it also had a mission to release male sexual desire on the other hand.

To be honest, witches magic power source was guy's semen and,
there are no other method to recover magical power other than having sex for the witches.

Therefore, for the witches, working to release male's sexual urges
s also meant recovering magical power at the same time.
The drugs for recovering magical power that she was intaking after every meal was also
produced by the master's semen.
(By the way, Mimi's mother is also a witch so, she knew about this)

Although Mimi was shocked to know about such facts but,
she was more determined to become a witch.
The master understood Mimi's feelings and, gave her a graduation test to become a witch.

The detail of the graduation test that was given to Mimi was
"To go on an adventure to collect guys' semen and power up as a witch"

During the adventure she will need to consume magical power to protect herself so,
she needed to have sex with a guy quite often.

Although the training details was quite intense which made Mimi confused,
but in order to become a fully qualified witch, Mimi took off.
