[R-Koga] Nii-chan's Property 1 (Nii-chan Senyou) [Shiro Translation] [Decensored]

A bold tomboy with short hair and a masculine shirt shouts that she’ll never forgive any guy who lifts a girl’s skirt, only to be humiliated and forced into a degrading sexual encounter with her older brother, Nii‑chan, who declares he’s become his exclusive property. As she struggles with the loss of her pride and the shock of incestuous domination, the story intensifies with explicit, non‑consensual acts and the relentless pressure of his control. The album delivers a tense, erotic conflict that blends humiliation, rivalry, and taboo family dynamics into a provocative, high‑stakes narrative.
