[Refrevo Comic (Harigane Shinshi)] Inran Succubus to Kegarenaki Sister o Party de Rouraku shite Kozukuri Harem Ecchi ~Otoko ga Umarenai Isekai e Shoukan sareta Ore ga Heroine o Ategawarete Kozukuri Ecchi 4~ (SCANMTL)

A horned succubus with a curling tail pulls the young man into a teasing, tangled isekai household, where his seemingly innocent sister remains caught in her orbit alongside an elf and other full-breasted heroines. Talk of a “saint,” shared wants, and a demand to be heard more loudly carries their private encounters toward fevered surrender, the women’s pleasure increasingly overtaking the brother’s protests. The mood then cools into mystery at the royal castle’s library, where a framed image, discussion of a curse and shared origins, and a girl’s hesitant expression promise that their bond reaches beyond the present.
