A girl with long black hair and bright green eyes, medium-sized breasts B-cup and medium-sized buttocks, stands in a shower cabin, completely nude, leaning her palms against the glass wall. Beside her, a completely nude man penetrates her anus with his erect penis. Side view, close-up shot. Warm, humid air, water droplets running down their bodies, soft overhead lighting creating highlights on their wet skin and the glass. An intimate, sensual atmosphere. Realistic image, highly detailed, photographic style.
