An older man finds Rei, a lovely adult music student, on a compensated-dating site, pays for one night, and brings her home to use as he pleases. She arrives soaked by the rain, revealing a gorgeous, big-breasted body beneath her demure appearance. Rei gives him a wary look that borders on contempt, but that only excites him more. The dirtier and more perverted she thinks he is, the stronger his lust becomes. He forces himself on the frightened woman, until the resistance in her breathing begins to give way to soft moans.
