He wants to use her to sire an army

He leaned closer, his massive chest heaving with excitement. "Oh, Velma," he said, his voice now a deep, rumbling growl that sent shivers down her spine. "I want what I've always wanted. I want to be the leader of Mystery Inc. And what better way to prove my dominance than by claiming the most precious members of the gang as my own?"

His eyes glazed over with a crazed lust as he described his twisted fantasies of having both Daphne and Velma at his beck and call. "Daphne," he murmured, his tongue flicking out to lick his sharp teeth, "always flaunting her curves and acting like she's better than the rest of us. I'll show her who's really in charge." His monologue grew more graphic, detailing how he'd make her beg for his monstrous cock, her screams of pleasure echoing through the cavern.

"And as for you, Velma," he turned his gaze to her, his pupils narrowing. "You've always been so clever, so resourceful. But now, your brains will serve me in a different way." He took another step closer, the ground shaking beneath his massive paws. "You'll bear my litters," he growled, his cock thickening at the thought. "A whole new generation of monstrous pups to do my bidding, to rule alongside me as I rule the world"

Velma's mind raced, trying to comprehend the depravity of Scrappy's desires. The cavern walls closed in around her, and she could feel the heat radiating from his monstrous form. Her breathing grew shallow, her chest heaving with fear. Yet, a strange warmth began to unfurl in her belly, a traitorous arousal that she couldn't deny.

Scrappy's gaze raked over Velma's body, lingering on the swell of her breasts beneath the tight orange turtleneck. His eyes glowed with a fierce hunger as he took in her voluptuous curves, the candlelight playing across the smooth skin of her exposed cleavage. He licked his lips, his tongue thick and pointed, as he imagined what it would be like to claim her, to make her his own.

"You see, Velma," he purred, his voice now a deep, resonant growl that seemed to vibrate through the very air around them. "You're perfect. You've always been the smart one, the one with the brains. And now, I need those brains to create an empire." He took another step closer, his massive cock swaying with each movement. "But first," he said, his eyes gleaming with malicious intent, "you'll give me what I crave. You'll give me your body, your womb, your very soul."
