[Shironeko Nokiki] Hinokami Sex. (Kimetsu no Yaiba)

Tanjirou Kamado's confrontation with the Mother Spider Demon takes a darkly sensual turn as the alluring arachnid matriarch overwhelms him with her embrace, her voluptuous, web-draped figure pressing close as she coos, "Rui, I'm sorry!!" while declaring, "It feels too good!" Even as Tanjirou resigns himself, thinking "Is this where I die..." and reflecting that he was supposed to defeat the demon, the Mother Spider Demon's intoxicating touch drags him into a spiral of pleasure, with his own sister Nezuko left helplessly crying "Kuuuhhh" and "Uuuuhhhh" as the tentacled, web-covered monster girl asserts her dominance over both siblings.
