Yuu Kawakami presents the eighth installment of her Perfect Best series, featuring an all-new challenge: sleep sex. Witness the transformation of a mother who is secretly fed her son's semen over and over, conditioned to become aroused simply by the smell of sperm. This release also includes four other handpicked episodes: a creampie-filled office setting with a dominant female boss, a lustful mommy who craves cunnilingus beneath her long skirt, and more. The absolute queen who continuously breaks new ground with each passing year invites you to experience 360 minutes of ultimate erotic bliss.
