Motto! Haramase! Honoo no Oppai Isekai Oppai Bunny Gakuen!

The main character loves huge breasts and bunny girls. He is the head of the App Development Club, which secretly and casually develops an adult bishoujo game called “Welcome to Impregnation Isekai Oppai Bunny Academy! (Provisional Title)” under the guise of legitimate club activities. (Officially, the club pretends to be an extracurricular circle, but in reality it is nothing more than the “Bishoujo Game Development Club.”) However, at the event dedicated to Parents’ Day at Usaki Academy, while debugging the game, the main character is suddenly transported to the alternate world of the very erotic game he was developing!

The world he entered is Yggdrasil, the world in which a bishoujo-style game was developed. All the female students, teachers, and even the school principal had amazingly huge breasts, and they were all dressed as bunny girls! It was a true academy of bunny girls, so exciting that his piston jumped with delight!

Later it turned out that his transfer to this world was caused by the academy. The main character was proclaimed the Legendary Great Teacher, who was tasked with saving the school, which was on the verge of closure due to the low rabbit deviation score. At the moment when the academy principal was searching his skills, his “Ultra Teaching Skill” activated!

The principal’s erotic body was soon “trained” through sex! Success! Moreover, it turned out that the sperm ejaculated into her body also significantly increased her deviation and rabbit mastery level! This will save the school from low rabbit deviation levels! When you look at the bunny-girl students with huge breasts and their mothers, your lecherous ambitions grow even more in the lower part of your body. With this dirty educational skill, you can conquer and sexually subjugate the school...... or even the entire other world?

The main character’s lower body is burning with the desire for perverted sexual forms and sexual relations between mother and daughter in this otherworldly academy. “I am going to give the students and mothers of this “Oppai Bunny Academy” perverted education!” Your ambitions for oppai bunny girls begin right now!
