Shiori is a young female civil engineer working hard at a construction site staffed entirely by men. She takes her job seriously, but there's another side to her that no one knows about... When they're alone, Shiori gently gives a blowjob to a new male worker who is excited by her body! She warms up her rain-soaked body by pressing it against his, and seduces him while giving him a massage...! The men around her can't resist Shiori, who even lets them have sex with her! In the end, she's forced to work at the office after being told that her allowance is lower than her guaranteed amount, and she's treated like a toy and even forced to satisfy the men's sexual needs!
