Demon Breeding (Magnifire)

In this dark Rosario + Vampire fan manga by Magnifire, Falla has forcibly conditioned her three sisters to serve as breeding vessels for Xarai's necro-demon offspring. One sister has undergone complete psychological fracture and now exists in a state of ecstatic delirium as she begins labor, expressing total submission and an addictive longing for Xarai's influence while the other two remain bound and resistant. The converted sister's pleas for continued pleasure and dominance contrast with the faint muffled cries of her still-unbroken sisters.
