Sakura has been married to her former boss Koji for a year, but she struggles with two problems: her awkward relationship with his adult son Hanzo and a dull sex life with a husband who finishes before she can climax. One night, still frustrated after trying for a baby with Koji, she goes to the kitchen for water and encounters Hanzo. He admits that he has been watching and knows his father cannot satisfy her, then overwhelms her with his endless appetite and powerful cock, repeatedly filling her with creampies.
