Waka's husband was buried under a mountain of debt, leaving her with no means to repay it. Desperate, she turned to an acquaintance, a doctor, and agreed to undergo treatment in exchange for her body. The doctor forced her to drink a sinister aphrodisiac and began taking full advantage of her. Overwhelmed by unknown pleasures, Waka gradually became addicted to the drug, her mind and body enslaved by its effects and insatiable sexual cravings. She eventually fell into a depraved dependency, endlessly craving both the drug and cock.
