Kijima Airi's work 'The Useless Wife' features scenes that utilize her thick pubic hair and includes three creampies, offering satisfying content. On the other hand, the lack of visible male genitalia during scenes and the focus on purely enjoying sex may not appeal to viewers looking for more in-depth interactions. The work depicts the compatibility of oral sex and oral NTR, intertwining with the wife's submissiveness, resulting in an intriguing narrative.
