VEMA-072 My friend's wife is a dirty tutor Kanako Ioka

Wataru failed his university entrance exams and is currently retaking the exam twice. Unable to bear the sight, his father asks his colleague's wife, Kanako, to be his tutor. Kanako immediately starts teaching him, but Wataru is dazzled by her body and is unable to concentrate on his studies. He even plays naughty pranks on her between classes. In the end, he purposely soils Kanako's clothes, puts her in the bath, and hands her a micro bikini, saying it's for a change of clothes.
