Shinsuke and his book-loving wife Yuki founded a publishing company together, but unable to keep up with the changing times, it is absorbed by Ozawa's corporation. Shinsuke works hard at the new company, yet cannot avoid a pay cut, so Yuki takes a secretary job to cover the loss. Ozawa then demands a kiss from Yuki as payment for the deficit her husband created. The kiss is obscene, intense and almost like sex itself. Once it becomes a daily ritual, Ozawa gradually begins demanding the real thing.
