I am Minoru Hisamichi, an unimpressive office worker whose sales numbers sit near the bottom. My strict boss Mito scolds me constantly, while my kinder boss Komatsu often steps in to help. One night during overtime, they invite me out for drinks, drag me along, then demand to stay at my place after missing the last train. I let them in with a little hopeful anticipation, unaware that the longest night of my life was about to begin as their hidden lustful sides took control and used my entire body until morning.
