My Son Is A Sex Monster.

Hana was dumped because her boyfriend said he couldn't keep up with her sex drive, and in her grief, she calms herself with intense masturbation. Meanwhile, a mother is troubled by her sex-monster son Yasuo, and while worrying about him over-masturbating and applying medicine, she peeks and their eyes meet. Saying 'Hole! Hole!' Yasuo attacks his mother, who handcuffs and restrains him. One day, at her wit's end with his excessive libido, Hana, who is searching outside for men to hunt, makes contact.
