A curvy, mature nun with a voluptuous figure, standing in a dimly lit, ornate church. Her habit is partially removed, revealing her naked, full-figured body with a prominent, round ass. The soft, golden light from stained glass windows casts a warm glow on her smooth, pale skin. She has a look of both guilt and arousal on her face, her lips slightly parted and her eyes half-closed. The church's intricate architecture, with its high vaulted ceilings and detailed woodwork, contrasts with the sensual scene. The image is captured with a high-quality DSLR camera, focusing on the nun's exposed body and the dramatic lighting. The overall atmosphere is a mix of sacred and profane, with a sense of forbidden desire.
