A demon, his body rippling with power, pins a succubus to the couch, her arms and legs splayed, vulnerable. His cock, thick and pulsating, teases her entrance before plunging in, filling her completely. She gasps, her eyes rolling back as he fucks her hard, her juices coating his cock, the smell of sex heavy in the air. He pounding increases, his body tensing as he prepares to fill her with his hot, sticky seed, her body quivering as she's pushed over the edge, her pussy milking him for every drop.
