YRNKNKJDVAJ-636 因极度暴露的 Cosplay 而备受关注的妹妹，说自己想要得到认可，因为 "被人看到会提升我的美感"，穿着暴露大胸的服装在我面前晃来晃去，所以 "乱伦是不允许的！"。Rimu Yumino 是一位拥有大奶子、渴望得到认可的年轻女性。
I found out that my younger sister was posting extreme cosplay images on SNS. As an older brother, I tried to correct her, but she seemed to be unconcerned by my sister's desire for approval and her boobs on display, saying, "Erotic cosplay is a great way to earn impressions. She is a disturbance to the order of the house, but at the same time, she is the object of my sexual desire... I pushed her down and forcibly had sex with her in cosplay in the name of punishing her and educating her, and ordered her to show me her cosplay in advance in the future... I ordered her to show me her cosplay outfit in advance in the future. This work is an excerpt from "My sister who is an extreme exposure layer wanders around the house in an erotic and outrageous breast-baring cosplay, so I made her understand by rubbing her tits and giving her a hard pinch" (part number: dvaj00636).
