A housewife named yura was subjected to aggressive sales tactics by a door-to-door salesman. Fed up with the man who targeted her when her husband was away, she called his company to complain and tore up his business card. The man, fired from his job, held a grudge against yura and forcibly raped her with his massive cock. Taken to the man's messy room and imprisoned, yura had her hands and feet bound and was forced to use lewd toys for training. As a 'sex slave' for men, she was made to masturbate and endure brutal deep-throat fucking. Unable to resist the man's strength, she obeyed his commands and swallowed his cum. Day after day, playing the role of a 'sex slave,' yura's personality crumbled, and she willingly dressed in maid cosplay to please the man. Reduced to living for pleasure alone, yura was dominated by the man's huge cock, moaning even outside their home.
