The attractive lady who sells probiotic drinks at the same time every day. As days pass, we become close enough that light sexual harassment is no big deal—why not take it all the way to sex inside the office? The probiotic lady who comes on Tuesdays is a single mother in her thirties, cheerfully tolerating the employees' playful advances. But in the president's room, she gives special services to secure bulk orders! On Wednesdays, an experienced lady known for pressing her breasts against people shows up—another day, another breast service! In the president's room, she gives him exclusive sex in exchange for a large purchase. One day, the single mother lady visits a lone employee working late, bringing him a snack, and in the empty office, they end up having a dreamlike sexual encounter!
