Department head Sato, the unattainable beauty of the company, has begun a secret affair with Hata, an ordinary rank-and-file employee. They act distant to avoid suspicion, but every exchanged glance makes their bodies ache and leaves a fresh wet spot in her underwear. At last, lunchtime arrives and neither can endure another second. The instant they are alone, they throw off their suits and get straight to business, fucking in the office and finishing with a creampie despite still being on the clock.
