[Kuroneko Akaribon (Kamisiro Ryu)] Akuma de Maid. [Project Valvrein]

When a horde of ravenous monsters fells the armored heroine Benibara, a horned demon maid with bat wings and a spade-tipped tail appears to sweep her flustered young master out of harm's way—and repays his trust in the most intimate way imaginable. Kneeling in her stockings, she milks him dry with her mouth before confessing it is her first time and inviting him to know her completely, her huge breasts heaving as shy questions give way to breathless declarations of love. By the final page he has stopped caring that she is a demon at all, emptying himself deep inside his cute maid as both beg for just one more embrace.
