To help with the household finances after her husband was laid off, she starts working as a maid for the Kaneko family. While on the job, she witnesses the hard erection of the homeowner's younger brother, Ryuji, and is shocked. As she flusters, Ryuji sexually harasses her and makes her perform fellatio. She experiences an unprecedented hardness that makes her wetter than ever before... After that, she seeks out hard penises, one after another, taking them into her mouth from the residents of the house and the men who come and go.
