OPPAI Succubus Academy: Sucky and Busty, Demonic and Lusty! is a visual novel set in the fantasy world of Faren'ch Deshka Girls' Academy. While its students are certainly top class in the bust department, the academy is in danger of closure due to its low ero rankings. It's up to Suguru to use the Book of Sexy Magic he was granted upon being transported into this world to help the prudish, busty succubi improve their ero skills and save the academy from being shut down!

Game system

After finishing the prologue and the first chapter, you can select any of the ten main heroines' scenes to advance through the game. The main story consists of 13 chapters called "stages," and each stage is divided into four waves. Completing a scene with a main heroine unlocks a new scene and advances you to the next wave. Once you complete four waves, you proceed to the next stage until you reach the final stage!

By going through the main heroines' scenes, you also unlock scenes with minor characters, mother-daughter threesomes, "character boob scenes", and plenty of group sex!
Don't forget to regularly check the main characters' profile screens! As you advance through the game, their Solo Grinding EXP and History is updated regularly, and you can listen in on their self-love sessions.

New to this installment is the "ejaculation countdown"!
The countdown will display during all ejaculation scenes—cumming inside, outside, boobjobs, blowjobs, and more!

The "magnifying glass" feature also returns!
Zoom in and out or rotate the screen during H-scenes, non-H scenes, and the main character profile screen. With this, you can focus on any part of the girls that catches your interest!

Background moaning is also supported!
During tit-sucking, blowjob, and penetration scenes, the sexiness is enhanced by the continuous playback of moaning, kissing, and sucking sounds in the background! This especially increases the impact and realism of the group sex scenes!

There are over 120 erotic CGs, even more than last time! And this time, there's even 21 fully animated sex scenes featuring Full HD Live animation, including scenes of all the minor characters!
The Steam version includes also Luxual, the ghost girl, additional scene DLC (as an Easter egg), which was separately available in Japan!

Other features

• Mother-daughter Threesomes!
  
• Boob-centric scenes focusing on each character!
  
• Nudist mode, secret voices, and barely there mosaics (which can be removed with the free special DLC)!

Story

Sakiba Suguru is a member of the occult club at Yumegafuchi Academy who endeavors to summon a succubus to satisfy his worldly desires. His cute childhood friend Mako makes fun of his delusions, but when he casts his lust-fueled spell... he suddenly finds himself in the bathhouse of a succubus academy in another world! Will he fall victim to the alluring charms of the lusty succubi, with their curvy hips and explosive tits!?

Alas, it turns out our protagonist has been summoned by the academy's chairman in a summoning gacha ritual in order to help revitalize the academy, because its succubi aren't lewd enough. The buxom chairman speculates—while jiggling her boobs in Suguru's face—that perhaps his succubus-summoning spell and her incubus-summoning gacha were synchronized and ended up crossing streams.
Apparently, the academy is in danger of being closed down by the Lilingard Ministry of Writhing, which has declared that Faren'ch Deshka must raise its ero rankings within a year. To save the academy and its source of ero-magical power, Suguru will need to turn the students into extremely lewd, sexy and obscene, wet dream-inducing succubi!

Suguru isn't confident, but the chairman uses her "Sex Scouter" succubus skill and discovers that he has been bestowed with a god-like level of erotic skill as well as the legendary Book of Sexy Magic! The chairman has no choice but to recognize his legendary powers and entrusts him with the nigh-impossible task of saving the academy. To turn the girls into full-fledged succubi, he'll have to seduce them! And with the Book of Sexy Magic at his side... it might actually be possible to conquer the succubus academy and get all the girls!
