Nezuko, in her demon form, corners Zenitsu in a secluded corner of the demon realm. Her eyes, wild with primal desire, lock onto his crotch. She tears off his clothing, revealing his throbbing erection. With a hungry growl, she takes him into her mouth, her big, round ass wiggling in anticipation. She sucks him deeply, her tongue flicking against his sensitive spots. Zenitsu grabs her big tits, squeezing and kneading them as Nezuko continues her oral assault, her demonic energy fueling her lust.
