Oppai Café ~My mother, my sister and Me~

Back in school, your teacher once dubbed you a "Maltese Tiger"—a rare, mythical beast bursting with untamed potential.
But potential doesn’t pay the bills. The real world hit hard, and graduation left you dead broke and jobless. Desperate, you relied on your mother—a lifelong housekeeper for the wealthy Lee family—to secure you a bottom-rung job at the Lee Group’s real estate empire. The man running the show? Shane Lee. The golden-boy heir you grew up alongside. A man you once called a brother.
When your mother fell critically ill, you went to Shane for help. Instead of a lifeline, he threw you a leash.
With cold disdain, he ordered you to move into the estate and act as a glorified dog-sitter, banishing you to the same servant's quarters your mother used to occupy. His parting words before leaving on a month-long business trip? Wait there, and know your place.
It was only when you arrived at the sprawling Lee mansion that you discovered the sickening truth. Your mother’s "room" was nothing but a cage—a suffocating, five-foot-high utility closet where a grown man couldn't even stand up straight.
But Shane forgot one crucial detail: lock a wild beast in a cage, and it doesn't become a tame dog. It just gets hungry.
You have exactly one month.
Starting from this humiliating dungeon, you're going to claw your way up the manor's hierarchy—from the ground floor to the master suites. You will make your way into the bedrooms of the women Shane holds dearest: his sister, his wife, and his mother. You're going to use your cock to conquer his closest kin, dismantle his pride, and steal his entire life for yourself.

The protagonist, who loves boobs and bunny girls, is the head of the App Development Club. It has been secretly and casually developing a bishoujo game—an adult game—titled "Welcome to Impregnation Isekai Oppai Bunny Academy! (Tentative Title)" under the guise of a legitimate club activity. (Officially, the club pretends to be a wholesome extracurricular group, but in reality, it is nothing more than a "Bishoujo Game Development Club".) However, on Usaki Academy's parents' day event, while debugging the game, the protagonist is suddenly transported into the alternate world of the very erotic game he had been developing!

The world he was transported to was Yggdrasil, the world setting of the bishoujo game the club was developing. Every student, teacher, and even the school director had spectacularly huge breasts—and on top of that, they were all bunny girls! It was truly a bunny girl academy so stimulating that it made his lower half feel like hopping with excitement!

It was later revealed that his transportation to this world was actually a summoning performed by the academy. The protagonist was hailed as the Legendary Great Teacher, tasked with saving the school, which was on the verge of shutting down due to a decline in its low bunny deviation score. As the academy's director performed a skill search on him, at that moment—his 'Ultra-Lewd Education Skill' activated!

The director's erotic body was soon "educated” through sex! Success! In addition, it turns out that the semen ejaculated inside the director's body had also dramatically increased her bunny deviation and skill level! This will save the school from a low bunny deviation! As you look at the bunny students with huge breasts and their mothers, your lewd ambition grows even more in your lower body. With this dirty education skill power, can you conquer and sexually subjugate the school...... or even the other world entirely?

The protagonist's lower body is inflamed with ambition for perverse sexual uniforms and mother-daughter sexual relations in this otherworldly academy. "I'm going to give the students and mothers of this 'Oppai Bunny Academy' a perverted education!" Your ambition for oppai bunny girls begins now!

The protagonist had two secrets:One was that he was an extreme boob lover, and the other was that he is actually a descendant of ninjas.
One day, when he opened an old scroll left behind by his late father,
he was transported to another world along with his step-sister (who has massive boobs) and his step-mother (also massive boobs)!
He ended up in a dream-like “Boob Spy Academy” where everyone, from students and teachers to even the school’s principal, was a spy and had massive boobs!
The Spy Academy was divided into three classes based on individual skills, and the students spent their days training hard and competing against one another. After falling into the dormitory bath, the protagonist found himself in a real bind, chased around by the busty spy students (who were completely naked).
Just as he thought he was saved by the principal’s arrival, he was immediately assigned a certain “mission.”
"Could you please track down the enemy spy who has infiltrated this Spy Academy?"
It turns out an enemy spy has infiltrated the academy, and the principal was at a loss.
Apparently, the boy who came from another world possesses special skills and is destined to save the academy from this crisis. At that moment, the “Perverted Mission Skill” activates! A mission that makes the principal go wild is triggered! After the protagonist successfully completes the perverted mission, the principal becomes convinced that he is the academy’s savior.
Using this skill, he must conduct a lewd investigation of the busty spy students who wield influence over the academy, and their mothers! The busty spies he targets aren’t easy to deal with; they’re after the information the protagonist brought from another world. A lewd espionage battle against these busty spies, each with their own quirks, and the honey traps that come at him! Use your super-lewd mission skills to track down enemy spies and, at the same time, subjugate the Spy Academy with lewdness!
"I’m gonna use my lewd skills to investigate the busty spy students and their moms,
and strip them naked!"
The protagonist’s cock-tastic mission, undertaken as a secret assignment, is about to begin!
