Husband Ryoma and wife Natsu's teacher Fujiwara was injured and the couple decided to take care of him. Natsu takes care of Fujiwara, who took care of her husband's work. However, Fujiwara was inflating her desires as she became a married woman by adding sex appeal to her firm skin. Then, Fujiwara, who was climbing the stairs while being supported by Natsu, fell down and buried his face in Natsu's crotch. Natsu resists Fujiwara's horny tongue, which moves like a living creature, but feels her body twitching.
