40-over friendship between two 40-year-olds. No matter how many times they spend an intense night together, they don't know anything about your true identity...

Amemiya is a 46-year-old gay man who works as the editor-in-chief of a literary magazine. He has been in a friendship with "Aki", who is the same age as him, for three years. Aki-chan has a quiet demeanour, but when he gets turned on, he is extremely erotic. He perform fellatio on me in the bath, and then raises his hips in bed and invites me to come... That doesn't stop Amemiya, but he knows that when Aki is exceptionally erotic, it's when something is wrong at work - and he knows it. Still, he doesn't pry into anything and doesn't promise to do so again. That is how the relationship has continued up to this point. But Amemiya can no longer cover up his desire to cross that line...?
