[Osushiteikoku (Hamachi)] Yametoki! Nishi Kyoudai (Yanineko)

Two cat‑eared siblings, a sister and a brother, share a cramped bedroom where the brother awakens with an erect cock, prompting a shocked gasp and a teasing confession that he should have just asked to be taken while she slept. Their playful banter quickly turns raw as they discuss incest, raw sex, and marking, culminating in a heated encounter that ends with a creampie despite their sibling bond. The scene shifts to a bathroom where they joke about the lingering scent of cum, while another cat‑tailed friend teases them about seeing them in the morning, underscoring the taboo thrill of their secret liaison.
