"Fuck me! Oh God, fuck me!" Robin gasped, her world swirling in a kaleidoscopic vision of raw pleasure.
Paul slipped his cock out of his sister's cunt until the end of his prick lay throbbing between her tight, frothy pussy lips. Then he lunged back in, grinding the base of his dick against her slit opening.
"God, this is great!" he moaned, running his tongue over her tits. "So fucking great!"
Robin couldn't have agreed more. Her brother's thick, long prick totally filled her guts with hard, throbbing warmth. She could feel the outline of his dick as it pressed wetly against her tender, sucking tissues. The sensation was a million times greater than she could have imagined.
"Fuck me hard!" she gasped. "Fuck me like you did Gina!"
"Don't worry about that," Paul said, chewing on her nipples. "I will, baby sister. I'm going to fuck you all night!"
Robin shivered with ecstasy as Paul began a slow pumping motion, sliding his huge shaft deeply in and out of her guts. She grabbed his asscheeks with her hands and began forcing him harder against her crotch. His balls rolled up and down the insides of her thighs; two thick, large nuts filled with a hot, throbbing load of cum! She dug her fingertips into his dark, hairy shitter.
Paul could feel her pussy muscles relax somewhat, now adjusted to his prick. He began shoving his click in and out with increasing speed, thrusting his cockhead savagely against her backbone. He knew he could come at any second, but he wanted this feeling to last forever. He clamped his teeth around her breasts, swirling his tongue around on the hard, rosy nipple. It throbbed and vibrated against the roof of his mouth like a large clit.
Robin's pleasure seemed to know absolutely no limits. Every thrust of her brother's cock seemed to jam in another hot bundle of release, thundering upward, exploding inside her lungs. She opened her mouth and yelled a silent scream, her face contorted with ecstasy.
"Christ, I don't know if I can hold on any longer!" Paul grunted. "My nuts are on fire!"
"Go ahead!" Robin gasped. "Shoot me full of hot cum! Give it to me! Iwant it!!"
A sharp, delicious vision of his exploding cock seared in her brain. The thick, creamy loads of hot cum that had poured into her mouth would soon be filling up her pussy. Just the thought made her shiver with anticipation.
Paul grabbed her shoulders and jerked his body forward, grinding the base of his prick brutally against her cunt opening. His balls nestled wetly against her shitter. For a brief second, he stopped all movement, then began plowing into her box like a wild animal.
The first, glorious glob of steaming jism splattered into Robin's cunt with such force, she thought she heard her teeth rattle. Then another quick load followed the first, forcing it upward, smacking against her backbone.
"Fuck! Robin! Fuck!" Paul chanted, his voice matching the rhythm of his spurting cock.
Robin was in heaven. The hot wads of sperm gathered in the back of her churning pussy, forming a lava-like river of sticky, bubbling warmth. She could feel the jerks of cum squeezing her tissues outward, trying to make more room for the other loads that gushed from his cockhead. Then she felt the squishing river of fluid stream forward, alongside the pumping shaft, and squirt from the bottom of her pussy.
"Pump me full!" she begged, feeling the oozing drops of jism soak into her asshole. "Give me all of it!"
Paul began throttling her pussy with such force, his sister began sliding up the bed. He dug his toes into the sheets to get better leverage, and held her by the shoulders. Their bodies smacked together wetly and noisily, with each inward grind. He exhaled a growl.
"All of it!" he said. "Take it all!"
He gave a final, savage jerk, emptying the last of his exploding load deeply into the back of her pussy. Then he stopped all movement for a couple of seconds, enjoying the sucking, convulsing motion of his sister's cuntal canal.
"You're not going to stop, are you?" Robin asked. "I want you to fuck me forever!"
Paul laughed softly. "Hell no, I'm not going to stop," he said. "I'm just getting my second wind!"
"Good!" Robin said, caressing her brother's ass. "I think I could do this for a hundred years!"
"You might want to eat sometime," Paul said.
"I would," Robin said. "I would eat your cum for breakfast, lunch and dinner!"
Paul began working his cock in and out of her pussy with slow, deliberate motions. His shaft was blanketed in a creamy, sucking mass of muscle that seemed to suck on his dick like a thousand hungry mouths. Again, he stopped fucking.
Robin opened her eyes wide. The idea of having that gigantic rod of meat up her shitter filled her with delicious horror. She had no conception of anything, except blinding, brutal pain. And yet, when the thought of his doing it registered, a dull ache centered at the base of her spine.
"Would it hurt?" she asked, knowing when she said the question, she really didn't care.
"Yes," Paul answered. "A little at first."
"Mmmmmnnnm, good!" Robin said. "I want to do everything!"
"I thought you would," Paul said.
He pulled his cock out of her pussy and rolled her over on her stomach. He eyed the firm, rounded curves of her ass and moaned.
"God, this is going to be good!" he said. "So fucking good!"
Robin looked around and saw her brother kneeling between her legs, his prick bobbing and slapping against his stomach. She was somewhat shocked to see, that his prick was covered with pinkish cream. Paul noticed her expression.
"Virgin blood," he said in explanation.
"Will my asshole bleed also?" she asked.
"Of course not," Paul answered. "Now you get on your knees, and I'll just slip my cock inside. When you think you can take more, just push backward. I won't hurt you."
He reached under and scooped a wad of sperm from her pussy with his fingers, then rubbed the liquid around on her tiny, dark shitter opening. He slipped his middle finger inside with one stab.
When his finger jammed into her asshole, Robin flinched with pleasure. It was just the right size! Again, the idea of having ten inches of cock rammed in her shitter filled her with fright, and at the same time, raw hunger.
Paul began working his finger back and forth, loosening up her shitter walls. When he felt her muscles relax, he thrust in two fingers, held closely together.
"You about ready?" he asked, puffing his fingers out.
"Yes!" Robin answered, awaiting the savage pain to smack into her body. "Go ahead!"
The funny thing was, there was no pain at all. She felt the slick pressure of his cockhead against her shitter opening, and her muscles stretch easily.
"Is it in?" she asked. "I thought it would kill me!"
"Just the end of my dick," Paul answered. "And I told you it might hurt a little. But it doesn't have to."
"What do I do now?" she asked.
"Just move back a little. Take as much as you can, and then stop, if it starts hurting," Paul answered.
Robin took a deep breath and wiggled her ass, pushing back a couple of inches. She felt her brother's cockhead slip inside her shitter canal, pressing upward, grinding against her tissues. Then she stopped.
"Is it all in?" she asked, knowing it must be.
"Not quite," Paul answered, looking at eight inches of cock still outside her body. "But almost."
Robin squeezed back a little further, taking in more of his prick. She inhaled quickly and then thrust back faster, feeling his shaft jam savagely into her guts. Instead of asking her brother if she had taken it all, she wanted to see for herself. She pushed back hard. Christ, there was more! It felt like his cockhead was squeezing into her throat, about to pop out of her mouth!
Paul was amazed that his sister wasn't screaming in agony. She had taken almost all of his cock, and not a yelp. She must have nerves of steel, he thought!
"Now?" she gasped. "Is it all in now?"
