Mariana's petite body trembles as she gazes upon the ocean's leviathan, its towering, rigid form a testament to its lust. She tentatively reaches out, her tiny hand wrapping around the beast's massive shaft, feeling its pulse. The creature's low rumble encourages her, and she leans in, her small mouth struggling to engulf the immense head. Saliva drips down her chin as she tries to fit more, her throat constricting around the invading flesh. The sea beast's pleasure mounts, its hips bucking as it yearns to bury its monstrous cock deep inside Mariana's tiny body.
