A man hires a prostitute but encounters a sexually frustrated office lady who keeps returning receipts. "Don't make me lose my food bill..." she says, and then engages in unprotected sex at home and in the office. (Miyajima Mei, START-274)

One day, the delivery girl I ordered turned out to be Ms. Miyajima from the accounting department of the same company!? The meticulous and strict Ms. Miyajima, who always returned questionable receipts, came to my house under the guise of "Mei" and agreed to have unprotected sex in exchange for hush money… Afterwards, she satisfied me both at the company and outside the store, and our relationship developed into a convenient one. It's an interesting story.
