Fapping is more than just a game

A professor abuses his student during private lessons in Scoop’s Immoral Study, an adventure game published by Kaguya on Itch.io.

In Immoral Study, you take control of the sleazy professor Hitosuji, who offers private tutoring services to rich families. He’s very effective, having sent many students to reputable schools through his guidance; however, Hitsouji is also a rapist who coerces his students into sexual activities while pretending that they relate to the studying process in some way. His latest target is Reiko Shirakawa, a girl who attends an all-female school and has little experience with men, making her all the more gullible.

Throughout the game, you will be able to speak and interact with Reiko, searching for ways to get your hands on her while avoiding the ire of her stern housemaid. Most of the game is played by choosing options from a list of potential actions. Some of them will progress the story, while others may lead to Hitosuji getting caught in the act.

Immoral Study was originally developed and published by Scoop in 1995 for PC-98 systems and one year later for Windows 95 systems. The game has now been re-released by Kaguya on itch.io, who plans to later port it to a newer engine, just as with the past two PC-98 titles they've published on the platform. The game features a short story with more than ten CGs to discover, partial voice acting for the lead heroine and the original music from the PC-98 version of the game.


You are professor Hitosuji, a well-known teacher who possesses the remarkable gift of turning weak students into straight A ones. What's the secret of professor's method? As you might have suspected, the talented professor uses somewhat... ahem... unconventional means to attain this noble educational goal.

This time, the "victim" is a young innocent girl named Reiko Shirakawa. She attends an all-girl and has never had any real contact with men. Controlling the cunning professor, you must seduce Reiko by selecting correct choices that are presented to you at almost any given point, avoiding disturbances such as the ugly housekeeper in Reiko's house.
