Summary:
Tsumugi's hot boss doesn't get off like other guys do, so she's having all kinds of kinky sexual experiences because of him. It all starts with late-night sex at the office, and humiliation. Then she has to walk with a vibrator in her underwear, stream a masturbation session in the changing room, and pull off a public display at a hot spring... How much more can her sensitive body take!?

There's an extra that's released after the author completed the series in 7 chapters.
