Ao Mayuzumi, 31 years old, in her 7th year of marriage. Originally from Setagaya Ward. Her husband is 20 years older, currently 51. In their age-gap marriage, he is overly protective and restrictive of his young wife, not allowing her to go out and have fun. She only felt a sense of freedom when riding her bicycle to go shopping. Due to his age, sex with her husband is naturally infrequent, leading her to reminisce about the intense doggy style sex she had with her ex-boyfriend, a volleyball player, back in her student days. Wanting to experience intense sex once again, and driven by a spirit of rebellion against her controlling husband, she applied for this shoot.
