The Yura family, a single-father household. The father, who had raised his daughter Kana alone, deeply wished for her happiness. He harbored an academic inferiority complex, thinking, “Because I have little education and don't have a top-tier job, I've caused her financial hardship.” He constantly told his daughter that to avoid such struggles, she must get into a good school and find a good job. However, during a parent-teacher conference, the teacher informed him that Kana's current grades made admission to her desired school impossible. Upon learning this, Kana's father pleaded desperately with the teacher, “Can't something be done?!” And then, unbelievably, the father offered to sell his daughter Kana to the devil. “If you get her admitted, you can do whatever you want with her,” he proposed a monstrous backdoor admission scheme. The teacher's brutal deepthroat instruction. In a state of M-awakening, she self-deepthroats, squirts everywhere, and climaxes. Forced into deepthroating by her out-of-control father, then water-tortured in the bath. Finally, in a deepthroat threesome with the teacher, the school's chairman, and her father, she vomits nonstop! Twisted love turns the father into a madman.
