[I'm moralist (Yanagihara Mitsuki, InuSamrai, Henrybird)] NIEHL in the Prison of Seminal Servitude ~declaration of surrender engraved in the womb~ [Penguin Piper]

An elven princess is bound by chains and forced into the grotesque breeding chambers of the Demon World, where monstrous beings violate her womb and inscribe a surrender rune upon her flesh. The relentless onslaught of demonic spawn turns the prison into a nightmarish factory of endless impregnation, driving her toward a harrowing climax of mind‑break and forced gestation. The stark contrast between her desperate yearning for escape and the brutal, erotic domination creates a tense, visceral narrative that explores the depths of subjugation and primal desire.
