I actually watched this work, and it's an excellent piece that fully depicts the reversal drama between siblings. The setting is interesting from the start: a younger brother who always fails tests captures his sister's masturbation scene on his smartphone and uses it as leverage to flip the master-servant relationship. The development where the arrogant sister, who usually mocks him with 'You're so stupid,' is forced to obey after her weakness is exposed has an effective twist that draws you in.

Especially, Ren Gojo's performance shines. The change from her haughty attitude before submission to her meek demeanor after her weakness is captured is masterfully done, and her beauty combined with a non-irritating acting style enhances the work. The fact that it's produced as a subjective work is also highly commendable. Without being bothered by the presence of a male actor, viewers can immerse themselves in the feeling of personally toying with the sister, allowing for enjoyment without frustration.

However, one point of concern is that it doesn't fully utilize the appeal of busty actress Gojo. Despite the selling point being her soft J-cup large breasts, there are many scenes with her wearing a top, failing to make the bust a full highlight. At least in the paizuri scenes, I wished she would remove her upper clothing. Keeping clothes on halves the excitement, which feels like a waste. I hope the production team studies more on how to leverage the asset of large breasts.

Still, the varied situations, such as the slippery body washing in the bath or the mischief on the defenseless sleeping sister, are enjoyable. The scenes of kneading her soft body convey a sense of realism, as if you can feel the overflow in your hands. Overall, the theme of 'teaching the arrogant sister a lesson' is consistent throughout, making it irresistible content for fans.
