START-255 — Drugged-Sex Revenge on the Queen of the House: Arrogant Adult Sister Becomes Completely Submissive to Pleasure — Kamiki Rei

Not yet available to stream

I hate my adult sister. After our father lost his job, her income became the family’s lifeline, and she began ruling the house like a queen while treating everyone else as servants. Half joking and half seeking revenge, I secretly give her a libido enhancer concentrated to one hundred times its normal strength. Overwhelmed by the drug-fueled pleasure, she loses all resistance and becomes completely submissive, leaving even her adult brother aroused.
