Carrying this secret frustration, she confides in her regular bartender, Kondo. Kondo has long harbored feelings for Mio, and unable to restrain himself any longer, he suddenly takes her from behind. Her skirt is roughly pulled up as he thrusts into her with a fierce, powerful rhythm unlike anything her husband has ever given her. Gradually losing the will to resist, Mio succumbs completely, climaxing again and again in overwhelming ecstasy.
