Fingers curling around the thick cock base, pale hands pump slow and firm on the colorful tiled floor, her silver ring glinting with each deliberate stroke up the shaft. Black hair falls across her arm while she squeezes the swollen head, thumb circling the tip until precum beads heavy and slick. She grips tighter near the middle, twisting her wrists in rhythm as veins bulge under her touch, the indoor light casting shadows on her smooth skin. Pace quickens with short jerks at the top, her knuckles whitening from the pressure while the cock throbs hard in response. Full control stays hers through every teasing pull and release.
