Synopsis
DWARFSOFT’s debut title—a brother brand of ORCSOFT—presents a steamy, sweet tale of a voluptuous, well-endowed little sister!
Keiisuke Tsukikawa, whose father is a folklorist, returns home one day to learn a shocking truth. His beloved little sister Saki—innocent, pure-hearted, yet possessing a curvy, buxom body—harbors a dark secret: a succubus dwells within her. Or rather, that demonic form is her true nature.
As her true nature gradually awakens, driven by primal desires, lunar cycles dictate when her succubus personality emerges—nights when she becomes consumed by an insatiable hunger for male essence, unable to control her lust.
A sweet, steamy cohabitation with his lustful demon sister begins now…!
