Yuuka has been feeling exhausted and frustrated recently. Noa noticed this and deduced the reason for her melancholy: she was having fantasies about fucking Sensei in the ass and having them unfulfilled was leaving her hot and bothered. So Noa convinces Sensei to let Yuuka have her way with his ass. Of course, she decides to help Yuuka by loosening up sensei in advance~
