The demon, driven by insatiable lust, spews blue semen all over her, marking her as his. She shudders, feeling the hot, sticky fluid dripping down her legs. He continues to fuck her, his pace quickening, his cock swelling. She can feel every throb, every pulse, as he drives her closer to the edge. Suddenly, he pulls out, his cock glistening with their combined juices. He strokes himself, his body tensing, and with a loud groan, he releases another torrent of semen, this time covering her face and tits.
