In the dimly lit hospital ward, Nurse Yumi, dressed in her pristine uniform, can't help but feel the heat rising between her legs. She's been sneaking glances at Dr. Saito all night, his confident demeanor and skilled hands making her throb with desire. As she checks on a sleeping patient, she slips a hand beneath her skirt, rubbing her clit furiously. Just as she's about to climax, she hears footsteps. Panicked, she freezes, only to be caught in the act by Dr. Saito, who smirks, "Naughty nurse." Their secret tryst begins.
