A fierce and sweet lecture from an egocentric sadist.

-- "You think you can make me cum with a blowjob like that?"

Tsukasa, who works in a male-oriented sex industry, adheres to an ultra-efficient philosophy, making money solely by giving blowjobs, with no actual sex involved.

One day, he mistakes AV staff member Yuugo for a customer and makes a move on him.

As always, he tries to make him cum with his famous blowjob technique, but he calls him "bad at it" and starts a sadistic lecture, only to find that he ends up cumming first...!?
