She smirks, satisfied by his submission. "Very well then." Reaching out, she places a delicate hand on top of his head, tilting it backward ever so slightly. His heart races as she descends upon him, their lips meeting in a passionate, hungry dance. Teeth sink into his neck, drawing out moist cries of pleasure mixed with pain. Blood rushing through her veins, she savours every drop, drinking deeply, her own hunger temporarily sated…for now.

"Remember this moment, human. You belong to me now." And with that, she vanishes into the depths of the swamp.

With one swift motion, she ripped open his shirt, exposing his chest to the cool night breeze. Growling low in her throat, she latched onto his jugular vein, sucking greedyly at the rush of warm, sweet blood flowing freely from the wound.
