Slow rhythmic forward-and-back rocking motion, her body sways with each thrust, large breasts bounce and jiggle naturally, long black hair swings gently, she pants with mouth open and tongue out, eyes rolling up in pleasure, cheeks flushed, sweat glistening, gloved hands grip the sheets, chain on collar sways. Camera static, slight slow push-in toward her face. Sound: soft moans, heavy breathing, wet skin slaps, faint chain jingle.
