Free Download Female Spy Undercover Investigation: Holy Sex Academy

Our protagonist, a female spy named "Mashiro," was born with a body that cannot feel sexual sensations due to a secret technique passed down from her family.
Since she is invincible and oblivious against all things sexual, she regularly achieves overwhelmingly positive results in both erotic training and erotic combat.

However, when she infiltrates an educational organization, the "Academy of Erotic Arts," her insensitivity seal is removed by the enemy leader!
Her first time feeling sexual pleasure...
Her first sexual climax...
And, for the first time in her life, a sexual desire surges up within her...!

The nasty, lustful traps and enemies won't show mercy to anyone, not even to a female spy who knows nothing about erotic things!
With her immaculate female body now completely unresistant to lewd attacks, and her sexual knowledge completely ignorant
of lewd things in general, will Mashiro really be able to successfully complete her undercover investigation...!?

In order to discover the true nature of the academy, which is constantly riddled with dark rumors, she transfers to the academy as a student and begins her espionage activities.
However, something seems a bit strange about the academy's educational landscape...
It seems like everything that happens is erotic, and she has no choice but to learn about sex through her own actions.
In the end, she gets subjected to unreasonable penalties...

As the undercover female spy repeats her daytime life and nighttime investigations, her body becomes more and more sexually developed. The sexual sensations begin to haunt her everyday life...
At this rate, her body will be ruined by sexual desire before she can uncover the academy's evil deeds... She must do something, before her true identity is revealed!

Put on a tight-fitting infiltration suit, and explore the dark building filled with security machines and lewd, otherworldy creatures!
Various traps are set up! They will stimulate the female spy's sexual desires, and arouse her inner lust...!

Will you play like a traditional spy, sneaking around your enemies, or will you take them head-on with bold moves, earning money and items? You decide!

Harsh, erotic scenes will torment the female spy, both in battle and on the field, hindering her undercover investigation...!
If she is defeated and captured by the enemy, she may be forced to take part in erotic punishment games, or may be given irreparable erotic aftereffects...?

You can enjoy various undressing patterns, such as removing only the top or bottom, wearing only underwear, opening the chest area, or leaving her in a damaged state.
In addition to the default short tomboy haircut, you can also choose long hair, or even a ponytail.
Changing hairstyles and clothing will also affect many of the event scene CGs.
Please enjoy the lewd antics of your favorite female spy.
