Rururu to Sasara no Sensei☆Oshiete: Boku wa Onna no Obocchama

Rururu to Sasara no Sensei☆Oshiete: Boku wa Onna no Obocchama is a Japanese erotic visual novel with a crossdressing theme. The player controls Yasuhiko Tsutsumi, a man who is hired as a home tutor for a young master named Rururu Daikinzan who lives in a rich mansion. Although Yasuhiko thinks that Rururu is a boy, he later discovers that she is a girl who has been raised as a boy according to the wishes of her late father. Since Rururu lives an isolated life in a mansion with no boyfriend, she is completely clueless about sex, so Yasuhiko takes it upon himself to teach her what it's all about. Their sexual lessons may result in Yasuhiko also bedding some of the other female characters too.

The game features Japanese voice acting for all significant characters except the protagonist.
