Sex Drive (Manga) Vol. 1 - My Listless Instructor

When one woman is afflicted with a disease that causes her to go into heat, she winds up in the world of sex-espionage and paired with a handsome, experienced man!

Jun’s life is turned upside down when she is afflicted with a strange disease and becomes a Venus. As a Venus, Jun produces excessive pheromones and can go into heat, affecting those around her—which makes her quite the liability. After she is inevitably fired from her job, her only option is to work with an intelligence agency that specializes in sex espionage! Unfamiliar and inexperienced with both spy work and sex, Jun is paired with the aloof and handsome Issui. To help Jun become more comfortable and used to the more intimate parts of the job, Issui takes the lead, teasing and touching Jun in ways she’s never before experienced. But when she’s brought to the brink of pleasure, begging him to go further—he can’t! 

Despite Issui’s dysfunction and Jun’s shyness, a desire grows between them as they embark on their missions. But things between them are sure to remain purely professional… right?
