After the fuck-party with Chelsey and the guys, Randi was sore for days. The memory of the two cocks plunging in and out of her pussy at the same time almost made her come again.
She would get all wet just thinking about it. Her cunt still ached from the fierce ripping fuck they had given her. But when she touched it with her fingers it throbbed and oozed, and she knew that if the guys were near, she would beg to have them do it to her again.
She also had a hard time getting out of her mind the sight of Chelsey being fucked in the pussy and the ass at the same time. Just recalling it made her pulse race. Her own tiny asshole fluttered and clenched as she thought of it happening to her.
And yet she herself had been crushed between two men on two different occasions, feeling their hard cocks fucking in and out of her cunt and coming in hot wild bursts of screaming pleasure. She knew it was only a step from what she had done to Chelsey's squealing ecstasy.
Her parents were away on vacation, leaving her and Billy alone for the week. And dwelling in her imagination on the events of the party, Randi totally forgot about being alone with her younger brother, and the opportunity they now had to repeat their earlier encounter. But obviously Billy was aware of it.
She passed down the hall one day in the late afternoon after she had finished work and glanced into Billy's bedroom through the open door as she walked by. Billy was naked and sitting on the edge of his bed. His hard young body caught Randi's admiring eye.
Billy's shoulders were broad, his torso muscular, his thighs powerful.
Randi lingered in the doorway, looking at him, letting her eyes finally drop to the long thick hanging rope of his huge cock. Again she could hardly believe her eyes. The blood beat in her throat.
Billy smiled at her. She couldn't help grinning back.
"Don't you think you should put on some clothes?" she asked him.
"Why?"
"It's not decent."
"Why're you looking, then?" he asked.
"I… can't help it."
As she watched, Billy's incredible cock began to swell and rise. She became even hotter, feeling her cunt itch and pulse, her nipples throb.
God, we can't do it again! she thought. It was so wrong even to do it once! I can't let it happen. I'm the oldest. It's up to me to stop it.
But she kept remembering Mike's large cock, which was not even as big as Billy's, hammering in and out of her while Chelsey was getting double-fucked next to her at the party. Her cunt could still almost feel it.
Her brother's prick was now standing and throbbing like a huge purplish salami. He walked toward her, holding his prick in one hand. His eyes burned into hers.
Randi could feel a tightness in her throat. In spite of herself, she could feel her cunt getting wet and pulsing insistently. She backed away as he approached her, still not taking her eyes off his magnificent jerking cock.
"Billy," she said softly. "You know we can't."
Billy kept coming. He pushed her back against the wall of the hallway.
Then he reached out and took her wrist. He drew her hand down until her fingers brushed the stiff shaft of his twitching prick.
"Oh Jesus!" Randi gasped.
Her fingers curled around his stiff prick. Billy bit his lower lip. His cock got even harder and hotter in her hand.
"We can't, Billy!"
"Nobody will know," he said hoarsely.
"We will!"
"We kept it a secret last time."
"I know, but-"
Suddenly Billy had his hands under her sweater. They slid up to her bra. He squeezed her full tits through the fabric.
"I want to feel them in my hands," he whispered.
"Billy, don't!" Randi whimpered.
But Billy was too far gone to stop. He crushed his mouth down on hers.
His tongue stabbed between Randi's lips. She gasped and squirmed but was unable to escape from him.
Billy pulled her sweater roughly up over her head, biting and kissing her smooth neck. His fingers tore at the clasp of her bra. Randi panted heatedly as she tried to pull away from him.
He couldn't get it open. His urgent fingers bit into the smooth skin of Randi's back. She squeezed his hot, huge cock in her hand, almost instinctively.
"God, Randi, I've got to have you!" Billy panted, pulling at her bra.
"Don't, Billy, don't!" she whimpered.
But his strength finally won out. The fabric of her bra snapped, and he ripped it off her. He took the torn piece of cloth and flung it down the hallway. His eyes were raging with lust.
Randi could feel her knees weaken. Her body grew pliant and yielding.
She knew she wanted him as much as he wanted her. He kissed her shoulders and her throat.
His mouth explored every inch of her throbbing tits. His tongue flicked her sensitive nipples. Randi moaned and shivered.
"Ohhhh God, Billy!" she sighed.
He sucked one into his warm wet mouth, holding her tit in both hands and kneading it. Randi felt a hot delirium of lust sweep through her quivering body. She grasped his huge prick in both hands and rubbed it eagerly.
"God, I want you to fuck me," she whimpered. "God, I want you to fuck me."
She slumped to the floor of the hallway with him. Billy took her other round tit in both hands and lashed her swollen nipple with his tongue.
Then he sucked it hard. Randi shut her eyes and moaned.
She pulled on his enormous prick, feeling it jump and strain with urgent life. Then she slithered down his body and peppered it with hot kisses. Her fingers rubbed his balls, and she closed her wet lips around the ballooning head of his thumping prick.
"Unnngggpphhh, God, Sis!" Billy groaned.
Suddenly, gushers of cum spouted out of his jerking cock into Randi's face. She had forgotten how little control he had.
"Oh Jesus!" she gasped, sucking his cock back into her mouth and swallowing his jism eagerly.
She held his pumping cock and gulped wildly until he collapsed back onto the carpet, panting helplessly. Then she licked the last drops of cum off it and wiped the dripping beads of jizz off her cheek.
"Billy, you've got a wild one here," she said. "It just goes off like a rocket. Next time give me a warning, okay?"
"I'm sorry," her brother said sheepishly.
Randi gave him a sisterly kiss on the lips. She felt a little selfconscious, having just gulped down his cum. On top of that, she realized that her own young body was still burning with need. He had gotten his rocks off, but she was still hornier than ever.
Nevertheless, she tried to get control of herself. She patted his limp cock affectionately with one hand.
"No need to be sorry," she said. "It's good it happened, in a way."
Randi felt his cock quickly growing hard again next to her fingers.
Within seconds, it was stiff and throbbing, a hot giant ready to fill her runny cunt. God, this kid is a miracle! she thought, looking at her brother's massive prick.
"You said you wanted me to fuck you," Billy said to her.
His hands crawled all over Randi's smooth body. His mouth found her tits again and sucked sharply. Randi moaned and twisted under his rough assault.
"Oh, Billy, Billy!" she panted. "Look, I've got an idea!"
"I want you, I want to fuck you!" he gasped.
"How would you like to do it in… my ass?" she asked.
"Really?" Billy's eyes lit up.
Randi nodded yes. From the frantic throbbing of his cock, she could see he was excited by the idea.
"But you'll have to promise not to be too rough, or to hurt me, okay? I mean, you're a little too strong sometimes."
"I'll be careful."
"Let's go in my bedroom," she whispered, slithering her tongue into his ear.
Billy grabbed her and pulled her down on the carpet. His hand found her wet cunt and he jabbed two fingers up into it. He bit her neck, and Randi moaned uncontrollably. She was afraid he would rape her right there.
"Billy, please!" she moaned. "In my bedroom! You can fuck me! Please!"
"Shit, I can't stand it!" her brother panted.
Randi stood up and pulled him to his feet. She could hardly take her eyes off the huge twitching stalk of his prick. It excited her when she thought of what was in store.
"Now you go in the kitchen and get some butter or something," she said.
"Something slippery, to keep you from killing me. Okay?"
"Okay!"
She picked up her torn bra at the end of the hall and went to her bedroom. There she pulled the covers down on the bed and sat on the edge, waiting for him and trying not to shiver with excitement.
Billy stood in the doorway, holding the butter plate from the kitchen in one hand. In his other hand, he clutched his throbbing cock. It was a huge swollen shaft of flesh, and Randi gulped as she realized where it was going.
God, maybe we shouldn't after all, she thought as her brother approached the bed. She began shaking uncontrollably. Billy sat down next to her. He put the butter plate beside them.
He pulled her down next to him on the mattress, running his eager hand all over her naked tits.
"I want to fuck you! I want to fuck you!" he chanted softly in her ear.
"Are you going to let me fuck you in the ass?"
"Maybe we'd better not," Randi whimpered.
"Oh yes, oh yes, we've got to," Billy said, turning her over onto her stomach. "I want to."
Her brother's hands found the smooth pale cheeks of her ass. He squeezed and kneaded them passionately. Randi lay her head on her arms and tried to stop shaking.
Then suddenly the sensations grew even wilder. Billy was actually kissing her asscheeks, pulling them apart and running his tongue up and down the crack of her ass. Randi squealed and wriggled crazily.
"Oooohhnnn! Billy, where did you learn to do that? Agghhh!"
"I just wanted to," he murmured.
"Ungh!" she gasped as she felt him slip a finger into her ass.
God, it'll never work! she thought. It hurts already! And that's only his finger!
But Billy quickly spread the soft butter all over two of his fingers.
When he began to fuck her asshole with them this time, Randi relaxed and let the feelings of lust spread through her body. It felt good. She began to squirm, swirling her ass back and up into the motion of his hand.
"Ohhh yesss, Billy, yes!" she moaned.
"Jesus, Randi, your ass is beautiful!" her brother gasped as he handfucked it, opening her up.
"Are you going to fill it up with that giant cock of yours, little brother?" she asked, whimpering uncontrollably as her sexual need got the better of her.
"You bet," Billy said.
She watched over her shoulder as he began to swab the butter all over the enormous shaft of his prick. Soon the whole thing was glistening and slick. Billy put the butter aside.
She watched him move in behind her asscheeks and nestle his huge twitching cock in the crack between them. Then he pulled her asscheeks apart. Randi held her breath. She clenched her teeth.
"Oh God, Billy, please, please don't hurt me!" she whimpered softly.
"Jesus, it's so big!"
"I won't!" Billy gasped, inching the bulbous head of his stiff cock into the pink, puckered ring of her asshole.
"Owwwnngg!" Randi cried out as she felt it penetrate her.
She shut her eyes and winced as he forced the massive rigid rod into her. It felt like a telephone pole. Her whole body throbbed and shook with incredible hot fires, stabbed to the quick by Billy's probing cock.
He did not stop pushing until it was embedded deeply inside her.
Randi's entire body felt impaled on it, stuffed to the splitting point.
She could not even moan or cry. Small helpless sounds of panic mixed with pleasure came from deep in her chest.
"Ohhhhnn God, it hurts, don't move!" she cried, burying her face in the sheet.
But the discomfort merged gradually into fantastic pleasure. Billy was crouched on top of her back, panting and groaning softly. Randi turned her face up to him.
"Okay," she murmured. "Now, do it slow. Fuck me slow, Billy. God, it feels good!"
Greased by the butter, Billy's gigantic prick began to fuck in and out of Randi's ass. The sensations were excruciating for both of them.
Randi only realized in the midst of her own moaning that she could hear her brother's moans intermingled with hers.
Now she knew why Chelsey had seemed so overcome by ecstasy. Randi's whole quivering young body felt crammed with hot cock. She whimpered and squirmed, clenching her teeth and hissing uncontrollably as she tried to bear the fiercely intense feelings.
Soon she got onto her knees, which tilted her marvelous ass up into Billy's frantic thrusts. He grabbed her hips and fucked his enormous prick deep into her asshole, making Randi cry out with mingled pleasure and pain.
"Annngghh! Ungg! Oh shit!" she moaned, feeling sizzling darts of pain spray through her impaled shitter.
"God, Randi, I can't help it!" Billy panted.
But the last thing she wanted him to do was stop. She got one hand to her crotch and began rubbing her swollen clit in frantic rhythm with his sharp plunges. The pleasure was so intense that she could barely keep from collapsing under him.
Already she could feel the hints of the pulverizing orgasm that was about to swallow her. Billy kept jabbing his huge prick deep into her ass, making her wince and shudder, then bloom with agonizing hot spasms of pleasure. Sunk in a wild delirium of lust, she grunted softly and gasped with crazy passion, swirling her skewered ass back and up at Billy's drilling cock.
"Unnnggghhh God, yesss! Ungggh! God, it goes so deep! Oh, God yes, do it harder, Billy! Unggghh! Yes, yes, yes!"
Billy was just as wild with lust as Randi was. He got up on one knee and fucked his huge stiff prick deep down into her asshole, drilling and drilling her with it until Randi was a groaning, quivering wreck.
Each lunge of his massive cock down into her ass made her see stars.
She pinched her clit with her fingers, and suddenly her entire straining body was swallowed by an intense orgasm. It knocked the breath out of her, and she lay whimpering and gasping as Billy's cock erupted inside her ass at nearly the same moment. Then a second wave of spasms hit her, this one even more excruciating than the first.
"God-Billy! Anggheeee! Oh God, oh shit, unggghh, oh, again!"
The intensity was agonizing, almost unbearable. She clenched her teeth and hissed with choking pleasure, feeling her asshole pulse and flame as Billy's cock jetted strings of warm jism into her. He didn't stop fucking her roughly during the entire orgasm, and that just made Randi have more climaxes, hot short violent ones that left her limp and mewling with exhaustion.
Finally Billy stopped moving. He slumped forward onto her back. Randi collapsed face-down on the mattress. Her brother's throbbing cock was still buried deep in her ass. She winced each time he moved.
"Billy, take it out slowly, okay?" she asked as she felt him start to withdraw his prick from her wounded asshole.
"Okay."
"Ohhhhnnnn!" she moaned, biting her lip and grimacing as the prick slid out of her.
She rolled over and kissed him. Billy was grinning with guilty pleasure.
"God, I can't believe how you raped my little ass so hard, Billy," she said to him, reaching down to caress his limp cock.
"I couldn't help it," Billy said sheepishly.
"But I loved it!" Randi murmured to him. "Jesus, I thought I was going to die of coming."
"Me too."
"You liked it?"
Billy nodded vigorously. "Can we do it again?"
Randi could still feel the throbbing and burning in her poor ravaged ass. His warm cum was still leaking out of it. The thought of doing it again left her momentarily faint.
"Maybe sometime!" she whispered. "But you nearly killed me! I've got to recover first!"
"Can you do it the other way?" he asked eagerly.
In her hand, she felt his incredible cock jumping to life once again.
At the same time, she could feel her pussy beginning to bubble with juice.
"How can you still get a hard-on, after that?" she asked him.
"It's easy with you, Randi."
He clutched her naked tits in his hands, squeezing them excitedly.
Randi had no trouble guiding his long stiffening prick into her runny cunt. They were lying next to each other, and she threw one leg up over Billy's hip.
"Unnnggghhh!" she groaned softly as his cock fucked deeply into her, filling up her tight cunt.
"Oh gosh, Randi, I love to fuck you so much!" Billy gasped.
"God, you don't love it any more than I do, little brother," Randi said, embracing him and rolling over on her back.
She raised her legs until her knees were draped over his shoulders.
That made his huge cock fuck deep into her with each sharp thrust. She shimmied her ass and chewed his ear, driving Billy wild again with young, eager lust.
After the violent fucking he had given her poor asshole, this was pure pleasure for Randi. His cock was gigantic, but the feel of it cramming her pussy made her quiver with bliss. She pumped her groin up into his piercing thrusts, growing faint as the sensations of a hot new orgasm began to approach.
"Oh, Billy, I'm going to come again!" she whimpered. "God, you fuck me so good! You've got such a great cock! Ungggh! God, yes, I love it when you stab me real deep like that! Unggghh!"
Billy's hands dug into her young smooth flesh. He fucked his stiff cock into her, panting and fucking her with quick hot jabs as his own climax grew closer. Randi shut her eyes and bit her lip as she felt his prick begin to shoot cum into her.
How he could have anything left, she didn't know. But the cum spouted out of his surging cock, filling her inflamed cunt and making her groan with pleasure as an orgasm engulfed her squirming body.
"Aaaghhhh!" she groaned loudly as the fires of her climax swallowed her. "Unnnggggh, oh, Billy!"
Twisting and wriggling under Billy's stabbing cock, she cried out with incredible pleasure. Billy kept fucking her until the last drops of jism dribbled from the head of his plunging prick. Then he slowly put her legs down and pulled his cock out of her clinging pussy.
Randi pulled him down next to her and kissed him.
"I can't believe you, you incredible guy," she said breathlessly. "You really know how to fuck. That prick of yours is the best there is."
He grinned sheepishly. "You think so?"
Randi nodded. She was ashamed of herself for realizing that she was thinking of the next two days, while her parents would still be away on vacation. By the time she and Billy got finished fucking each other, she thought, they would be lucky to still be alive.
