Immoral Game Master.

A guy named Mario is roped into being a Game Master by his dad, who works at a video game company. Not thrilled about it, he digs into the system and discovers that the sensations in the game can be felt in real life. Intrigued, he decides to experiment and zeros in on a shy girl named Koharu Takashina. Koharu dreams of becoming a charismatic, helpful character in the game—totally unlike her real self. But the role she’s slapped with? A prostitute. Assaulted by thugs in the game, her womb starts throbbing with desire, even though she’s still a virgin in reality.
