[Seto Yuuki] Level C Minus [Decensored]

An eager nurse in a frisky uniform leans over a helpless patient, proposing a daring anal encounter while a glinting plug promises intense pleasure. She taunts him with a challenge to take the front‑hole while the dildo remains inside, and he gasps as the level of his arousal plummets to C‑minus. The scene builds to a climactic drop as she invites him to pull the plug out, sealing the perverse exchange.
