Synopsis: Last Order wa Ojou-san de Dekiai Jouren Kyaku ni Kyuuai saretemasu

"Shall we continue until my moans overflow with pleasure?" It may seem odd, but I yearn for the embrace of someone who has lost even their own identity... Mei, the daughter of a restaurant owner, has a problem with one of their regular customers, Chikage. Despite her warnings, he continues to smoke. However, there is something captivating about him. At a party, Chikage suddenly changes his behavior, and Mei finds herself constantly swept off her feet by him. He takes her to a hotel for refuge during a rainstorm, and while watching an adult video, Chikage suggests that Mei should "experience" it with him. "From now on, I'll guide you every step of the way." In all its raw and unbridled passion, this is Chikage's first and final true love.
