Kohaku, the seemingly prim and proper tutor, lets her wild side out as she teases her sensitive nipples, her eyes gleaming with desire. She pulls down her top, revealing her ample H-cup breasts, and pinches her rosy peaks, gasping at the pleasure-pain. Her student, Swing Nagase, watches in awe as she straddles him, grinding her wet pussy against his hardening cock, before taking him deep into her mouth, her big tits bouncing with each thrust.
