Sex-loving sensitivity queen Tsukinoe Sui faces a full-day prank: she must hold back her wild orgasm cries no matter where the action starts. She is suddenly penetrated, teased with toys under the table during lunch, and secretly brought to orgasm during a package shoot, in the car, and at a male performer's home. She squirts hard while desperately stifling her voice, trembling and apologizing as she cums through three vigorous sex sessions and creampie action.
