Even the fat size of him didn't bother Maria. Her pussy had expanded without a qualm, and there he was, huge prick easily inserted. But, God, how would it feel when he started moving the thing? Right now he was just slipping it in, very slowly, very gently, getting her accustomed to the presence of his cock in her cunt. She was leaking so fluidly, that he had no trouble easing in deeper and deeper, and there was no pain at all.

He stopped sucking her tit. His hands cupped her tits, his lips nuzzled her neck and cheek. She turned so they could kiss mouth-to-mouth, tongues flipping back and forth friskily.

"It feels so Goddamn good." She sighed into his open mouth. "I want to keep your cock up my pussy forever."

"You're so tight, I may not be able to get it out." He smiled at Maria and licks at her mouth.

"I could dig it." The girl laughed. "But when are we gonna fuck?"

"Right now!" he began thrusting harder.

Maria's eyes got really big. He was like a log in her cunt, and she could feel every inch of him, moving inside her. The walls of her pussy expanded to make room for him, and he thrust again, burrowing deeper into Maria's cunt.

She tightened up, gasping, but he fucked into her tightness and her fingers assured her that he was no in her pussy, all the way up to his balls. God, was she that deep? Could she hold the entire ten-inch prick in her young cunt? She'd never have guessed it, but here was the proof in her hand, his sac of balls wiggling on the lips of her pussy.

"I can dig it!" She moaned. "Fuck me now! Split me! Give me the whole fuckin' thing!"

And that's what he did. His penetration picked up speed. She was tight and unused to the size and thrust of the cock that was reaming out her pussy, but Maria's cunt was flexible. It had to adapt or bust. It adapted, of course. The wetness flowing from her inner walls helped immeasurably, soaking his prick, making the strokes endurable for the ecstatic young girl, as she humped to meet her uncle's driving cock.
