After actually watching this work, I was first drawn in by the special sibling relationship that continues from puberty. The setting where the younger sister provides daily breastfeeding cleverly depicts the eroticism hidden in everyday life, and the psychological conflict of the older brother growing up unable to wean adds depth to the overall piece. Particularly, the development where the possessive desire explodes with "until my sister gets a boyfriend..." is enough to stir the viewer's emotions.

Actress Momojiri, while the breasts tend to be the focus, naturally showcases her healthily developed abdomen and jawline, which, though sometimes noticeable,反而conveys a realistic charm. In scenes focusing on acts and buttocks, her acting shines, with plays that lack intensity yet ooze eroticism being impressive. Her seemingly monotonous expressions反而make one feel the depth of emotion, and the moments of climax are quite erotic.

The story progresses with a "big brother..." development, and in the scene where she angrily confronts the useless brother, Momojiri's acting stands out especially. The final erotic scene blends cuteness and sexiness perfectly, and the work's overall ebb and flow in intensity enhances the value of watching it through. The good focus point is commendable, but there are voices that the actress's breasts and nipples don't match their preferences, with some fans hoping for a similar work starring Washio Mei. Overall, the uniqueness of the situation and the realism of the acting are reasons to recommend this work.
