Hikari is a hard-working office lady who uses her body to milk men's sperm and rises through the ranks. She milks the overbearing manager with a handjob and then leaves work in style. When the section chief comes on to her after hearing the rumors, she grabs his balls and milks him until he submits, then blackmails him and takes all of his connections for herself. She makes a client submit with a handjob and footjob and secures a contract. When she drugs the section chief and lures him into a hotel, she immediately restrains him and has sex with him, milking him until she can't get enough of him. Once she's done, she leaves him alone, saying good job.
