A sweet-loving girl joins a long-established confectionery company. Eager to contribute, she works not only as a receptionist at headquarters but also actively sells products at the direct-sales shop. Petite and beautiful with a traditional charm, she looks stunning in a kimono. However, she catches the eye of the ignorant son of the company's founder and is kidnapped and imprisoned. Subjected to relentless power harassment, she is mentally and physically broken. Though she desperately resists, her body betrays her—her nipples become highly sensitive, reacting intensely, and fluids begin to seep out.
