Takafumi prepares breakfast for his wife Makoto, who rushes off to work helping her senior teacher Yasuno. Takafumi's dream of opening his own restaurant is close thanks to Yasuno's help and the principal's investment. That afternoon he is called to the principal's office and told to prepare for the store opening that weekend. On the morning of the weekend, Takafumi arrives at the store location only to find his wife Makoto already there with Yasuno. What follows is a mix of betrayal, blackmail, and difficult choices as Takafumi is helplessly tied to a chair and forced to watch and participate in his wife's sexual submission to Yasuno, leading to deepthroat, paizuri, raw pounding, and creampie scenes while Makoto faces the painful decision between her husband and the man who holds their future in his hands
