Airi Suzumura, a file clerk by day, a sex-crazed bookworm by night, can't resist the pull of her carnal desires. She's a bonus video sensation, her slender frame writhing in the humid air, her glasses slipping down her nose as she indulges in her solitary pleasures. The camera captures her every move, her every moan, as she slips a finger, then two, into her eager pussy, her body arching in ecstasy. She's lost in her lust, her world reduced to the sensation of her own touch.
