Kana, who switched careers from night work to a daytime esthetician, begins seeking stimulation during work breaks. She starts rubbing her crotch against clients' paper pants during treatments. Her actions grow bolder, eventually pressing the tip of the penis against her groin and simulating penetration through the pants. This lewd behavior pushes an unsuspecting male client past his limits, causing him to release a massive load of sperm. Feigning coincidence, they proceed to full intercourse—an act forbidden at the shop. The erotic scenario continues as Kana falls into a submissive role, repeatedly brought to climax by creampie after creampie.
