Holy Slave Academy 3

St Mary's Church holds many big breasted sisters. Some of them crave for uncontrollable pleasures. And today wishes come true.

The protagonist is Mashiro, a female spy whose body was made unable to feel sexual pleasure from birth due to a secret technique passed down through her family.
Invincible against sexual attacks, she spends her days achieving overwhelming success in erotic combat and erotic training.
However, in the school management organization "Erotic Arts Academy" that she infiltrates this time, the enemy's leader breaks the spell that made her frigid!
She feels sexual pleasure for the first time.
She reaches a sexual climax for the first time.
And for the first time, sexual desire surges within her, overwhelming the female spy...!
Erotic enemies with ruthless erotic traps show no hesitation even to a female spy who is a novice in erotic experience!
A young female body with no resistance whatsoever to lewd attacks, she is... With her utterly ignorant sexual knowledge, will Mashiro be able to successfully complete her undercover investigation...?
She transfers in as a student to investigate the true nature of a school rife with dark rumors, engaging in espionage.
However, the school's educational scenes seem strange...
It appears that only lewd content unfolds, and she is unwillingly forced to learn about sex firsthand.
Finally, she is subjected to unreasonable punishments...
As she repeats her daytime school life and nighttime undercover investigations, the female spy's body undergoes lewd development, and these lewd sensations begin to follow her even in her daily life...
At this rate, her body will be ruined by sexual arousal before she can expose the evil deeds... She must do something before her true identity is revealed!

“Wouldn’t it be a waste to simply trap and kill a woman that fine?
Crush her confidence, her dignity—over and over again.
Grind her down completely, until she’s worn out and begging,
bowing her head to me repeatedly.
I’ll carve the ‘true role of a female’ into her body, one piece at a time.
How does that sound?
Doesn’t it make your heart race?”
Betray your “ally” by siding with the “enemy”!
The ultimate corrupt power-move!
Until the title of “Strongest War Princess” is wiped from people’s memories,
drown her in defeat and disgrace.

18 years ago, Cardinal Gilbert was punished by the archbishop for committing a mistake in the capital's archdiocese. He was demoted to the remote seaside town of Kynaston, where he would succeed the deceased ex-bishop and govern for 20 years.

Time passed by quickly, and Kynaston became a prosperous commercial town. The daughter he had adopted also celebrated her 18th birthday.

Set in modern Japan, this game follows the silver-haired, red-eyed, large-breasted CEO, "Riaza Iarlen," as she solves various cases.
Besides Riaza, the game also features the blonde beauty "Shimada Eugen" and the pink-haired beauty "Harada Dechiko."
Furthermore, you can create a "male character" that you can control in some events, and change their name and hairstyle.
The game includes missions such as infiltrating a casino in a bunny girl outfit, and patrolling the city at night to repel suspicious individuals and strange beings.
While engaging in missions involving sexual servitude, known as "Underground Holy Grail Missions," you and the three heroines take on the darkness swirling within the city.
