Ichika and her current boyfriend have started preparing for their wedding taking place in four months. They approached a wedding planning center, and this time the person in charge of their wedding is Ichika's ex-boyfriend! She used to love him very much, but due to his contemptuous personality, Ichika proactively broke up with him. Nevertheless, the ex-boyfriend knows Ichika's sexual preferences well and is aware of her sensitive spots, bringing her to the peak of pleasure. Upon meeting him, old memories flood back. The current boyfriend is unable to satisfy her; before he can even enter, he goes soft, leaving Ichika devoid of the feeling of climax for a long time. The ex-boyfriend also longs for Ichika's body; he purposely changes the meeting time to discuss the wedding so that Ichika's husband cannot attend. When Ichika is alone with him, he continuously stimulates her weak points, making it impossible for her to resist him. And during those four months, Ichika constantly let him enjoy her body, making her an extremely lewd woman. The two even fucked each other as soon as the wedding was taking place! Even though she is married, Ichika does not want to leave her ex-boyfriend, she wants to enjoy the pleasure of sex that he brings, which her husband cannot give her.
