Yuka Osawa, O Ohashi Mi Ku, and Rin Tokiwa gather in a luxurious lineup for a SPECIAL on submission and orgasm training. The three women are attacked at a resort, and their vacation villa suddenly transforms into a rape prison. Their mouths and anuses are violated at the men's whim as they become mere sex tools. Their bodies awaken to pleasure, surrendering despite their minds' resistance. Trapped in an endless cycle of hell, they can never escape, forever imprisoned.
