College student Risa became a tutor in a single-parent household. The son is quiet but lusts after Risa's body. The father also had his eyes on the young flesh. The son, together with his delinquent friends, drugged Risa to sleep and used her as a living sex doll for pleasure, inserting his penis to experience ecstasy. The father discovered that Risa was being used as a toy by his companions every day, but he too savored Risa's young body.
