Miyu participates in a lighthearted, fun-filled talk session with the crew while completely relaxed. When the staff proposes the "Standing Doggy Style Championship," Miyu becomes curious, listening intently to the rules before being half-forced by the staff with, "Wanna give it a try?" Initially treating it as a game, her excitement gradually builds as the male performer—the Standing Doggy Man—appears and starts touching her body. Soon, her shaved pussy is dripping wet and his cock is rock hard, throbbing with desire, driving them into intense, instinct-driven hardcore sex. Miyu thrusts her big ass backward, fully immersed in carnal pleasure as the competition unfolds. What will be the outcome of the Standing Doggy Style Championship?
