Shûdôjo Rushia: Kegasu (1978)

The scene starts with a young Asian girl in a black nun’s habit sitting on a couch next to a guy in his late 20s with short brown hair. They’re inside a dimly lit living room with a coffee table — looks like a cheap apartment. She doesn’t take off the habit, just lifts the skirt and gets on her hands and knees while he fucks her from behind, slow and deep. You see her face in profile, eyes closed, mouth open — actually looks into it. After doggy, she flips to missionary on the couch, habit still on, and he grinds down hard while she wraps her arms around him. Her small tits bounce a bit under the fabric — not big, but you notice them. Later there’s a clip of her climbing stairs alone, wearing white shoes, close-up on her legs and ass. Another shot shows her hugging the same guy in near darkness, both in silhouette. The last frame is her in bed, long hair, dim light, looking off to the side like she’s thinking about something. No speech, no music — just natural room sound and breathing.
