Known as a Kyoto socialite, Sumire Kisaki attends an elegant yet daring orgy party. She begins with a polite self-introduction, gradually becoming aware of the atmosphere shifting into something intensely erotic. With fresh stimulation arriving constantly, she is penetrated repeatedly, climaxing over and over in an unending wave of pleasure. The mood grows increasingly heated, as she actively seeks new sensations and deeper ecstasy within the frenzy.
