Yūtōsei Kurashina Mutsumi: Hamedori Nakadashi Dōga

Yūtōsei Kurashina Mutsumi: Hamedori Nakadashi Dōga is a Japanese erotic kinetic novel which tells the story of an honor student named Mutsumi Kurashina. Despite being friendly, pretty, and well-liked by most of the school, Mutsumi is still a virgin... something that is about to change. When she learns that a friend of hers is in financial trouble, Mutsumi makes a deal with a man over the internet who coerces her into having sex for money.

The game's user interface is different from most visual novels in that, during sex scenes, the dialogue may be displayed in speech bubbles to make the scene resemble a hentai manga, though this feature can be disabled to make the dialogue appear in the normal text window instead. The game also features a chapter selection menu, a save/load function, and voice acting for Mutsumi.
