He tapped the lips of her cunt with the head of his cock and she gasped, flinching, hips jerking but the rest of her held firmly in place.
"Tell me you're stupid. Tell me you're a dummy," he said.
"What?" She asked breathlessly, then shaking her head. "No. I'm not."
He started a slow rhythm, just up and down, cock resting heavy on her slit. Her hips jerked again but she was going nowhere.
"Oh, I will. Just have to do one easy thing. Just need to say something. You're a dummy. You can say that, can't you?"
"Nnn-no! Ah - I'm a- ngh..."
"Don't have to mean it, just have to say it. That's easy. Come on."
"B-but it's... s'humilating... I..."
"It's easy. Two syllables. Even a dummy could say it. Come on. Just once."
She bit her lip. She hesitated. He stopped his rhythm and let the head of his cock just part her, just a little.
It came out of her in a rush, in an exhale with her head thrown back.
"Good girl! See how easy that was? I think you should say it again."
He'd brought a hand around to thumb her clit, the head of his cock inside her now. She was panting. Whatever she'd felt about it being humiliating was melting by the second in the face of how much she needed the rest of him.
"I'm a dummy!" She said again.
Much easier that time. He'd started thrusting in, a little deeper each time but still not enough for her.
"Once more. I'll give you a little treat."
Once she'd finished he'd pushed right into her all the way, their bodies smacking together. She gasped, eyes wide, staring at nothing, and let out a groan as he started fucking her. Slow at first, but soon hard enough the bed was squeaking and anything even like a thought leaked out around his cock.
He lent down, grazed her ear with his teeth, and asked:
"Say it for me, I want to hear it."
"I'm your dummy! I'm your dummy! I'm dumb! Stupid! Oh God fuck yes brains leaking oh fuck."
"Good girl, that wasn't so hard, was it?"
"No no! So easy! Being a dummy is so easy! So gooood!"
He gave her a little kiss on the neck.
"Such a cute little dummy."
