Kazumi is an instructor at a sports gym in Tokyo. In the first scene, she gets wet from kissing and verbal abuse, and screams and climaxes many times during piston movements. In the second scene, she shows her true masochistic side by saying, "Please spank my ass." In the third scene, which was unexpected, she gets on all fours, takes my dick in her mouth, and I thrust into her from behind, and she finally goes home satisfied.
