Daite Hoshikerya Naite Miro summary:

“Did you cum when I thrust it in your throat?...pervert'' Miyama, who is in his third year of IT sales, was assigned a large project, but he couldn't find a system engineer to work with him in the company! The only person he can count on is Odagiri, a gloomy coworker who entered the company at the same time as him but has hardly ever interacted with. When he was drunk and throwing a fit, Odagiri told him, “Then come right now - right in front of me.'' The cold, dark gaze as if he's licking all over his body gives him a pleasure that can't be compared to fucking a girl…!? Erotic development love between a cool and unaware sadist and a flirtatious, lewd, and a masochist office worker.
