After drinks following overtime, coworker Kano Kashii, senior Yui Hatano, and junior Himari Kinoshita take one man to a hotel for a foursome. The three office beauties work together to attack three sensitive spots at once, from a triple blowjob at lunch to piling in while he secretly fucks Kano. It all turns into a wet, messy foursome, followed by raw group sex and repeated creampies during overtime. A dull office becomes a fantasy harem hotter than any brothel.
