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 wedding planner is actually Ichika's ex-boyfriend! She used to love him deeply, but she broke up with him due to his condescending personality. Nevertheless, her ex-boyfriend understands Ichika's sexual preferences well and knows her sensitive spots, bringing her to the peak of pleasure. Upon meeting him again, old memories flood back. Her current boyfriend is unable to satisfy her; he becomes flaccid before he can penetrate, leaving Ichika long deprived of the feeling of climax. The ex-boyfriend also longs for Ichika's body, and he deliberately changes the meeting schedule for the wedding planning so that Ichika's husband cannot attend. When Ichika is alone with him, he continuously teases 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.
