Join Kurumi Suzuka and her colleague Shima as they liven up a slow day at the Japanese department store with a little fun of their own. After a quickie in the stockroom, Kurumi can't get enough. She sneaks off to the lingerie section, where she plays with her toys, bringing herself to orgasm after orgasm, her moans echoing through the empty store. Meanwhile, Shima watches from afar, jerking off to his coworker's naughty display.
