[Necocoya (Kanna Hisashi)] Nettaiya no Heya de Neteiru Imouto wo Dousuruka

After noticing his sister murmuring in her sleep, the brother decides to investigate, his curiosity turning into a forbidden attraction as he gently touches her, his own body responding despite his shock. The tension escalates when he feels an unexpected, slick sensation clinging to him, and he declares that whether she awakens or not, his desire will continue unabated. This full‑color, incestuous tale of a sleeping sister and her brother is rendered with vivid detail, mosaic censorship, and a raw, rough‑translated narrative that highlights their intimate, taboo encounter.
