Newlywed Rei lives peacefully with her husband, but his rushed, clumsy sex leaves her deeply unsatisfied. Meanwhile, her father-in-law constantly touches and harasses her. One day he catches her masturbating and realizes how frustrated she is. From then on, he thoroughly licks her body and fucks her despite her disgust, awakening pleasure she cannot deny. From his perspective, Rei’s pale, sensual body and reluctant expressions are irresistible, and he delights in tasting every drop of her juices. Before long, the woman who hated his advances begs him to lick her more and admits his tongue feels better than sex with her husband. The father-in-law claims her body has already been saturated with his drool and invites her to continue.
