MDTM-009 Training a beautiful girl pet, JK Makoto (pseudonym) falls into the role of a masochistic slave

When an innocent beautiful girl is taught about male desires, she becomes addicted... The pleasure of "training" stains the hearts of adolescents who carry darkness in their hearts. Her body becomes excited when she is collared. The girl begins to feel happy being roughly treated as a human toilet. She will never be able to return to the innocent smile she had when she was a girl. Happiness is found in mating.
