A fetishistic video collection depicting the private pleasures and torments of Sawa Yuka, an early-blooming masochist who first became aroused by the expression "a woman being tightly bound," and has since been dominated by abnormal desires, dreaming of becoming a masochistic slave. Part 1 features newly shot private training on day one, including crucifixion-style torment, genital teasing with one leg suspended, spanking while restrained, anal training on a restraint table, teary-eyed deep throat with a strapon, and dual-penetration sex.
