Sachika, 27, is entering her second year of marriage. With her husband busy at work and rarely showing her affection, she's been using dating apps to seek relationships with younger men. Lately, she's been particularly fond of a male college student she's sleeping with regularly. However, her husband has recently started to suspect something, making it difficult for her to meet her lover. Because of this, she's asked her boyfriend to shoot a gonzo video of them having sex, deciding to satisfy herself with the footage instead.
