She steps it up.

She slowly raised a leg, the slits in her black dress revealing a toned, tanned thigh as she brought her heels onto the chair, between his spread legs.

She lowered herself, her thighs pressing, straining and stretching the dress, the heels digging into the cushion.

"But it's not enough to hurt you, is it?" she purred, her hand wrapping around his shaft. "No, you need something else."

His cock, pulsating with blood, was heavy and throbbing. She could feel it, the power, the dominance coursing through her, his naked vulnerability at her feet.

She slid her thumb across the slit, smearing his precum along the sensitive skin.

"You need to be humiliated," she murmured, her breath hot against his ear. "To be used."

Her free hand snaked around his neck, grabbing a fistful of hair.

"And I'm going to do both, Eduardo. I'm going to use you like a toy, and I'm going to hurt you."

She shifted her weight, bringing the heel onto his exposed thigh. The thin point dug into his flesh like a hot needle through butter, a drop of crimson forming on the white skin.

Valdés moaned, his cock twitching, his balls tightening in her grip.

"Oh, you like that, don't you?" she whispered. "Such a filthy pig, enjoying the pain."

She lifted her leg slightly, the point of her heel sliding along his inner thigh. It left a thin, red line in its wake, the wound shallow but stinging.

"Is this what you do with the prisoners, Eduardo? Tie them up and hurt them?"

He whimpered, his eyes closed tight.

"No, I bet you let them tie you up, and beat you with the riding crop until your dick is hard and your balls are tight. And then they fuck you, and use you like the dirty little pig you are."

His body trembled, his cock twitching violently.

"Come on, piggy. Cum for me," she murmured. "Let go and cum."

The leather creaked under his weight, his hips thrusting wildly. His muffled screams pierced the silence, his cock spasming.

He exploded, thick ropes of cum erupting from his cock, splattering across her black dress, coating her hand and exposed thighs.

Isabella squeezed his balls firmly, his cock still pulsating as his orgasm continued.

"Yes, little piggy, yes," she breathed. "You're mine now, and I'm going to use you and hurt you, and you're going to love every second of it."

His eyes rolled back, his body going limp in her arms.

She held him until his cock was flaccid, and his breathing had slowed. Then she stood, wiping her hand on the dress.

She ripped the gag off his mouth, the leather strap wet with drool.

"You were right, Mistress," he gasped, his voice hoarse. "I'm yours now. I'll tell you everything."

"Good," she said. "I'm listening."
