A mature, sexy milf nun with a toned, curvy body, wearing only her black habit skirt and white garter belt, bent over the altar in a dimly lit, ornate church. Her long, wavy auburn hair cascades down her back as she looks back with a mix of lust and guilt. A muscular priest in his cassock stands behind her, gripping her hips tightly as he thrusts into her from behind. The church's stained glass windows cast colorful, ethereal light on their entwined bodies. The scene is captured in a realistic, cinematic style with dramatic lighting and high detail, emphasizing the contrast between the sacred setting and their passionate, forbidden act.
