Oppai Muse

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!

A breast demon who uses her enormous breasts to squeeze out men’s semen. Engage in a fierce battle with Enano, the breast demon.

After botching a quest to stop a rampaging dragon and not scoring any loot you’re back farming slimes in a low level dungeon. Thankfully some adventurers come by looking to party up with you since you can’t cast offensive magic and are stuck with support spells. Unfortunately, they are an annoying lovey-dovey couple trying to have some risky outdoors fun.

Slogging through the dungeon is a pain, enduring the awkward flirting of the girl throwing herself at the unresponsive div of a boyfriend. Your only reprieve is boring combat against weak slimes. Eventually the group stumbles upon a room containing a magical grimoire and before Mr. Boyfriend enters you chant a cheeky spell trapping yourself and the clearly inheat beastwoman alone in a room together, and wouldn’t you know it she totally buys the whole “looks like this room was rigged with a magical trap that won’t open until the people inside have sweaty, intense, mind-breaking sex!”

Now, with the beastwoman, Anne, wrapped around your *finger*, why stop there? Use your devious mind and strange magic to fill out your new Oppai Party! Someone to tank backshot after backshot, someone who can keep you satisfied 24/7 with an amazing dicks per second rating, a healer to keep you energized for those long nights at the inn or on the road between quests.

In order to satisfy his sexual desires, the protagonist attempted to summon a succubus. When he began the ritual, he and his childhood friend ended up in a large communal bath at a succubus academy in another world! In Farench Deshka Girls' Academy, the succubus have boobs that have grown to the brim with milk and perfect bodily proportions. Our protagonist was summoned to this world by the director of the school who held a summon gacha on her own to save the school. The "erotic deviation score" of the school is too low. Therefore the government of Lilingard, the country of succubus in the world of Yggdrasil, is closing the school in one year. In order to save the school, the succubi must become more lewd and raise the erotic deviation score. To ease his dismay, the director grants him the succubus skill "Sex Scouter" which unlocks a vast amount of "Erotic Skills" that makes him surpass majin-level.

With the school's fate on the line, our protagonist has no choice but to become the legendary hero. And with the help of his erotic magic book that he received without permission, he will be able to save the succubus school. With this spellbook and new skills, it is now possible to conquer this school and become invincible in this world. It's time to rebuild the succubus school and build a succubus harem!
