In a world where demons roam, Nezuko and Zenitsu find solace in each other's arms, their bond deepening beyond mere friendship. As Zenitsu's hands explore Nezuko's curves, she gasps, her demonic instincts awakening. He strokes her horns, her tail, and her pussy, making her moan wildly. She returns the favor, worshipping his cock with her mouth and hands until he can't take anymore. They fuck passionately, their bodies entwined, their moans echoing through the empty halls of their hidden sanctuary.
