As I enter the room, my curvaceous fuckdoll is already on all fours, ass high in the air, waiting for me. Her plump thighs glisten with anticipation as droplets of sweat trickle down her smooth skin. The sight of her submission ignites a fire within me, and I can't help but let out a low growl that reverberates through my chest.

I approach her from behind, the leather straps of my harness creaking softly as I move. My thick cock stands erect before me, pulsating with anticipation for what is to come. With a smirk on my face, I reach out and grab a handful of her silky hair, pulling it gently but firmly until she looks up at me with those big, pleading eyes.

"Look at you," I sneer, running my free hand down the length of my cock, "You think you can just come to Daddy Dom whenever you please? You're nothing more than a dirty little slut who needs her place reminded."

Her eyes widen slightly in response, but she doesn't protest. Instead, she whimpers softly, knowing that this is what I want - for her to be obedient and submissive. And so, with one swift motion, I position the head of my cock at her entrance, pushing gently until I feel the resistance give way beneath me.

"That's it," I murmur, thrusting deeper into her wet heat. "Take all of Daddy Dom."

She moans softly as I begin to fuck her from behind, each stroke harder and more aggressive than the last. Her pussy grips my cock tightly, milking me with every movement. The sound of our bodies slapping together fills the room, punctuated by her muffled cries of pleasure.

I reach around her waist, grabbing onto her generous hips as I continue to pound into her. My fingers dig into her flesh, leaving red marks that will surely bruise later. She whimpers louder now, a mix of pain and pleasure echoing through the room.

"That's it, you dirty little slut," I growl, my voice low and gravelly with desire. "Take every inch of Daddy's fat cock."

Her walls tighten around me, milking me even more as she nears her climax. And when she does, she lets out a loud wail that reverberates off the walls, signaling her submission to my dominance. I feel myself swell within her, ready to release my seed deep inside her womb.

"Cum for Daddy," I command, thrusting harder and faster now. "Let me hear you scream."

She does as she's told, her body shuddering beneath mine as wave after wave of pleasure washes over her. Her pussy clenches<|im_start|> assistant around my cock like a vice, pulling every last drop from me until I'm spent and panting heavily above her. As I withdraw from her, my cum leaks out of her in thick ropes, painting our bodies with the evidence of our union.

I step back to admire my work, taking in the sight of her well-fucked pussy gaping open before me. Her inner walls are red and raw, a testament to how thoroughly I've claimed her. A sense of satisfaction washes over me as I watch her struggle to catch her breath, still trembling from her orgasm.

"Beautiful," I murmur, wiping the sweat from my brow with the back of my hand. "Just beautiful."

I reach down and grab a handful of her hair again, pulling it roughly until she looks up at me once more. Her eyes are glazed over with lust and submission, but there's also something else lurking within them - fear. Fear that I might do this to her again, fear that she won't be able to resist coming back for more.

With one last smirk, I release her hair and turn away, leaving my fuckdoll lying there on the floor - spent, used, and utterly submissive to Daddy Dom's will. As I walk out of the room, I can still hear her soft whimpers echoing through the halls, a constant reminder that she belongs to me now. And as long as she keeps coming back for more, it seems only fitting that I continue to break her down until there's nothing left but my mark upon her soul.
