オレたま

Kouta Satou is a hapless virgin whose body becomes the prison for the Queen of Terror, a demon bent on destroying the world, after a freak sealing accident locks her inside him. The only way to keep her contained is for Kouta to abstain from ejaculating for a full month. A lesser devil named Elyse, sent to free the queen, throws every temptation she can at him, turning his ordinary life into a thirty-day test of willpower.
