Every day, a man named Nakata searches for the ultimate free sex experience, dreaming of marriage—so he proposes to a sex worker! This middle-aged man visits the red-light district of Gotanda, exploring specialty brothels including M-sensei (BDSM), AF (anal), and large-breast-focused establishments. At the M-sensei parlor, he's dominated by a voluptuous S girl skilled in anal play; at the AF-specialty shop, he meets a girl who looks just like Natsuki Kato; and at the large-breast parlor, he's treated to skilled underboob titty fucks by an H-cup girl. Do sex workers truly fulfill their clients' fantasies? The answer unfolds inside the rooms!
