He takes her throat

"Now, I'm going to lubricate my cock with your mouth, or do you want me to take you dry? The choice is yours, but either way I'm fucking you. The only difference is how much you'll hurt."

"Lube." Isabella whispered, her voice a hoarse gasp. "Use my mouth."

"Good girl."

"Just, be gentle."

"Oh, I won't be. But if you bite me again, I'll fuck your throat so hard you won't be able to speak for days."

She nodded, and he pulled his finger out, bringing his cock to rest on her face. She opened her mouth and took the head in, sucking gently. His hands gripped her hair again, and he began to thrust into her.

Her tongue swirled around the head, her spit dripping down his shaft. He groaned, and pushed deeper, forcing his length into her throat. She gagged and struggled, but his grip was firm. He pumped his hips, using her mouth like a toy, and she did her best to stay calm. With one particular vicious thrust, he **** half of his length into her throat.

She couldn't breathe, and her lungs burned. She could feel his cock swelling inside her, and her vision began to blur.

He continued fucking her mouth, and her body trembled with each thrust. His balls were getting closer with each thrust, and she could feel the heat radiating from them. She closed her eyes and focused on her breathing, trying to stay relaxed.

After what felt like an eternity, he pulled out, leaving her gasping for air.

"That was only two thirds, can you believe it?"

She couldn't respond, her throat too sore and bruised.

"I'm not stopping until I see my balls resting on your chin, you understand?

"I'll try."

"Good girl."

He plunged his cock into her throat again, and she choked and sputtered. His thrusts were slower, but deeper, and she could feel his cock hitting the back of her throat with each stroke. She opened her throat as best she could, desperately holding her breath in as he gripped the sides of her head.

He started moving faster, and she could feel him getting closer. She tried to swallow, and the feeling of his cock sliding down her throat made her gag. He grunted and fucked her harder, his cock pulsing with every thrust.

"Fuck, you know how long I have waited for this? To take the virgin cunt of the President's daughter, make her mine, claim her as mine? It's going to be worth it."

She wanted to tell him to shut up, to stop talking about her like a piece of meat, but she couldn't. She was trapped, and there was nothing she could do.

Her jaw ached and her throat was sore, but she tried to relax, letting him use her. His balls were slapping against her chin, and his grip on her hair was getting tighter. With a roar of triumph, he held the back of her head and slammed her face into his pelvis, thrusting his entire length down her bruised and battered throat.

The sensation was overwhelming. Her entire body shook, and she felt her muscles spasm as she came. She was gushing, her pussy throbbing and contracting as the waves of pleasure washed over her. She couldn't believe it. She had just cum, from having her mouth ****.

Serrano pulled out, leaving her coughing and gasping for air.
