Amasawa Rin is a young wife in her third year of marriage, living a life of luxury with her capable husband. My husband and I work as a secretary for a company, but I have a secret that I can't tell my husband... The young, handsome, and talented president of a venture company has a hobby of making me masturbate in his office when we are alone. Now that I'm married and settled down, I can't help but seek excitement, so I started doing 'sex overtime' as I was told. The president looks at me as I lick him as I moan with my legs spread in an M-shape on his desk. He verbally abuses me, and instead of my beloved husband, he thrusts his huge dick into my uterus. I've become addicted to this stimulation, and I've ended up having an inappropriate relationship with an employee in the same department as my husband... If I call him to the bathroom and make him cum with a toy, the stress of my secretarial work will blow away, and it's time to relax! Sometimes, I'm attacked by a huge-dick employee with a pent-up sexual desire, and we have cowgirl sex in the elevator hall in the basement! I got married at a young age, but I wonder if a company like this is the reason my marriage with my husband is so loving?
