Alex came home from the hospital the following day, and his beaming smile could only be matched by Robin's. He lay in his room, trying to relax, but he was much too excited. His sister had given him a real welcome-home treat, but it hadn't lasted nearly long enough.
His cock suddenly sprang to life as he thought of those hungry lips sucking up and down his shaft, gobbling down his sperm.
God, could she suck a dick!
He looked at the clock for the tenth time in as many minutes. He didn't know if he could wait for her to get home from school. His nuts began to ache painfully, demanding release.
"Is that you, Robin?" he shouted, when he heard the door slam, Robin had a concerned look on her face as she bounded up the stairs. "Are you okay?" she asked breathlessly. "You sounded like you were in pain!"
"I am!" Alex answered. "I've had a hard-on all day, just waiting for you to get home!"
"You mean, you missed your little sister?" she asked playfully.
"Damn right, now get over here!" Alex said, motioning with his right hand.
"Wait a second," she said. "I've got to get undressed."
As she began slowly removing her clothes, Alex could almost taste the flavor of sex in the air. He looked at his sister's voluptuous body, the long, lean legs, the taut, upturned breasts, and the golden patch of hair that framed her tight, tiny cunt. He felt another dull ache throb into his nuts.
"Hurry!" he said. "Before I cum all over this cast!"
Robin went over to the bed and pulled the sheet away. She gasped as the thick hard cock came into view. She sat next to him and touched it lightly with her fingers.
Alex flinched. "Oh, baby!" he whispered, pulling her close. "Make me feel good!"
Robin kissed him gently at first, then began licking her tongue between his lips, her own hunger beginning to match his. She grasped his cock at the base and slowly jacked the shaft up and down. They moaned into each other's throats.
"Let me have your pussy!" Alex murmured. "I want to eat you out!"
Robin pulled herself forward, then straddled his shoulders, slowly inching her slit toward his open mouth. When his nose ground into her cunt hairs, she threw her head back and moaned.
"Mmmmmmm!" she said. "You do that so good!"
Alex clamped his mouth around the opening of her pussy and licked his tongue forward. The sweet juices of her body dripped into his mouth, almost driving him crazy with pleasure. He grunted with ecstasy as her throbbing clit brushed against his teeth.
"I love your pussy!" he murmured, his voice barely audible through the smacking sounds of his mouth. "So fucking hot and tight!"
Robin held the back of his head with both hands and pushed his face against her crotch. She quivered as the tongue thrusts became more demanding and hungry, inflaming her cunt with burning intensity.
"Eat me!" she whispered, already beginning to feel the first pangs of orgasm about to explode into her guts. "Oh God, chew it up and swallow it!"
A few seconds later, her sift canal convulsed around her brother's probing, darting tongue, trapping it inside her exploding pussy. She dug her nails into the back of his neck, and humped forward, pumping wildly against his face.
"Yes! Yes! Yes!" she chanted as each rippling stab of climax increased, thundering into the back of her cunt.
Alex grabbed her ass and pulled her downward, until his prick nuzzled against her box. He sucked her tits into his mouth and began chewing on the nipples as he thrust his hips upward.
Robin felt a new, raw wave of passion slam into her guts when his thick, round cockhead pressed against her climaxing cunt-hole. She squirmed around, slipping his cock into the back of her pussy with deliberate slowness, thoroughly enjoying the hard texture of his iron-hard dick.
"God, fuck me!" she whispered, grinding her pussy lips against the base of his cock. "Fuck the shit out of me!"
She reached around and grabbed his nuts, puffing them upward, against her asshole. The hairy, vibrating sensation made her ache all over.
"Mmmmmmmm!" she said, touching her breastbone. "I can almost feel you up here, you're so, big!"
She closed her eyes and arched her back, enjoying the tight sensation of having her brother's cock so deeply embedded in her guts. She slowly raised herself, shivering with delight as the thickness of his meat swelled inside her slit. Then, she quickly slapped her body downward, flexing the ring of cunt muscle as the deliciously warm shaft sank in.
"That's it, baby sister," Alex moaned. "Take every inch into your pussy!"
Robin began pumping up and down, bouncing on her knees, slipping the huge prod in and out of her frenzied pussy. Quick gasps of air hissed out of her lungs as her guts were forced upward, causing spasms to burn in her throat.
"God, I'd love to suck you and fuck you at the same time!" she whispered.
She hardly got the words out when her insides exploded with furious throbs of release. Orgasm crashed into orgasm, sending shivers up and down her spine, as her pleasure peaked with violent stabs of release.
"Oh, Jesus God!" she whimpered. "Oh, fucking Jesus, God fuck me!!"
As her pussy clamped around his cock like a greasy, sucking vise, Alex felt his own orgasm burn into the base of his cock. He jammed his crotch upward and slapped his sister's body downward at the same time.
"Take it, little sister!" he grunted, as the welling stabs of pleasure thundered up the center of his cockshaft. "Take it in your hot little cunt!!"
Thick, juicy globs of boiling sperm splattered deeply into Robin's guts, collected, then poured backward, forming against the underside of his dick. Wads of creamy jism spurted out of her pussy, gushing onto his balls, and between his thighs.
New, rippling pangs of ecstasy shot into the back of Robin's pussy. It seemed with each hot spurt of her brother's cock, he grew larger and harder. Her entire insides were aflame with delicious, all-consuming release.
"Fuck! Fuck! Fuck!" she grunted with a raspy voice. "Fuck! Fuck! Fuck!"
Alex ground the last of his load into his sister's slit, then relaxed. While he lay there, Robin continued to pump up and down, thoroughly milking his dick. Then, she too, stopped after a few seconds and fell forward.
"Oh, you've got the best cock in the world!" she moaned against his neck. "So big and hot!"
"How about sticking it in your ass for a little while?" Alex murmured huskily. "I've still got another load of cum just aching to get out!"
Just the mention of an ass-fucking, inflamed Robin with wild, hungry desire. Without removing her brother's prick from her pussy, she sat up, then turned around, facing his feet. She grabbed his cock with both hands and pulled her body upward. When the end of his dick flopped out of her hole, she guided it against the opening of her shitter.
"I can't wait!" Alex whispered. "This is going to be even tighter!"
Robin had to admit that what her brother said was painfully true. As his cock dug into her asshole, the ring of muscle around her tiny opening stretched to the breaking point.
"You're going to rip me apart!" she winced, gently lowering her ass downward.
Alex thrust upward, totally burying his prick in her guts. He felt Robin flinch with a mixture of pleasure and pain, her silky skin taut against his stomach.
"Stick my ball in your cunt!" he said. "I want all of me inside you!"
As Robin gathered his dangling, cum-smeared nuts into her pussy, the pain in her shitter disappeared as if by magic. A soothing warmth cascaded upward, tingling wetly into her backbone. She leaned forward and bent his knee to bring his left foot closer to her mouth. She licked out her tongue and ran it over and between his toes with smacking sounds.
"Don't move!" she whispered. "Just lie there for a few seconds! I love it with your cock and balls inside me at the same time!"
She began a hot, wet wash-job of his foot as she squirmed her ass very slightly against his crotch. Then as her intense ecstasy became uncontrollable, she sat up and moaned.
"Fuck me!" she whispered, her face contorted in agonized lust. "Tear into my asshole!"
When Alex began bouncing her body up and down to meet his jutting thrusts, his nuts flopped out of her pussy and smacked against the insides of his thighs. He felt Robin grab them again, squeezing them gently with her palms.
"Unh, this is better than I thought it could be!"
Alex groaned, watching his shaft pierce into her guts.
Robin couldn't have agreed more. As her driving pleasure became more evident, she began an up and down pumping motion that smacked their bodies together wetly. A new thrill of sensation pumped into the back of her cunt.
"Harder! Christ, harder!" she grunted, feeling the enormous cockhead streak through the slick walls of her shitter.
If Alex hadn't had a cast on his leg, he would have very likely lifted her off the bed, so great were his jamming thrusts. His long fingers dug into her tender flesh as he squeezed her waist and hips with his large, groping hands. He felt the base of his cock begin to jerk out of control.
"I'm… I'mmmmm… coming!!" he winced, feeling the first, gushing wad of hot sperm thunder up the center of his exploding shaft.
Before the volcanic-like glob of cream poured into her shitter, Robin's cunt burst in a flaming spasm of release. The orgasm dug into her guts wildly, filtering through each nerve, each muscle and bone. Then, as her asshole began to fill with the warming, slick blobs of jism, the pleasure increased powerfully, constricting her body with violent jerks.
Unable to move at first, she began grinding and pumping with full, force, when her entire being soaked with orgasm. She cried out a silent scream from a face contorted in anguishing, tormented release.
The walls of the room resounding with their gasps, their raspy, uneven breathing, and the smacks of flesh on flesh. It was several moments before they even began to slow their movements slightly. When they did, Alex was the first to speak.
"Fantastic!" he said. "Fucking fantastic!"
Robin pulled away from his body, still enjoying the throbbing sensations in her cunt. His cockhead slipped forward, then flopped out her shitter opening with a dull thud against his stomach. She threw her leg over and sat down beside his crotch.
"This is the best part!" she said, lowering her head.
She clutched his withering cock with both hands and pressed it against her lips. She licked up and down the shaft, sucking in the spent wads of cum with eager lapping motions. The cooling cream warmed again as she wallowed them around in her mouth, then reluctantly allowed them to ooze into the back of her throat.
"Mmmmmmmm!" she murmured. "It's so delicious!"
"You mean you like that stuff?" Alex asked sleepily.
"I could drink a million gallons of it!"
"Well, I don't think I have quite that much, but you can sure have all you can suck out!"
"You think you can go again so soon?" she asked, amazement in her voice.
"Why don't you find out for yourself?" he asked, pressing the back of her head.
The flavor of her musky asshole, clinging to his shaft caressed the back of her throat like a gentle spice. It mixed with the aroma of his cum, causing a tremor of excitement to rush through her body.
"I love your cock!" she gurgled, sucking the thickness of his prod deeply into her throat.
"Uuuuuunnnhhhh!" Alex moaned. "Suck it good, you little cum-eating cunt!"
He pushed his hips upward as he pressed brutally against the back of her head. He felt his cockhead smack against her tonsils, then sink into the back of her throat.
Robin was hardly prepared for such an immediate assault in her throat. She tried to take it all, relaxing her throat muscles, but it was too big! She gasped for aft and tried to pull away, but her brother refused to release the pressure that kept her there.
"Chew it, you little cocksucker!" Alex moaned, pumping upward. "Eat it into your throat!"
Robin began to squirm around as her breath left her. She thought her lungs would explode from lack of air, yet her brother only increased the pressure of his hands. She began to get dizzy and light-headed.
"Uuuuummmmphhhf!" she gurgled as she dug her nails into his stomach.
Alex let go of her head and flopped his cock out of her mouth. "What's the matter?" he asked.
"Don't you want it?"
"God, yes! But it's so big! Too big!" she answered, gasping for air.
"Just relax," he said. "Work on my balls for a while."
She pound her nose against the underside of his shaft and pulled his nuts between her lips. The hairy, hard texture scraped against the roof of her mouth causing her to shiver with ecstasy. She grabbed his cock with both hands and began flopping it around on her face, pressing the loose foreskin against her eyes.
"You'd better get back to sucking my dick," Alex whispered, "or I'll cum all over your face!"
His words seemed to inflame the hunger in her throat. She pushed his nuts out of her mouth with her tongue and licked upward until her lips burned against his cockhead. With one movement, she gobbled the entire length of his dick into her throat.
"I thought you said it was too big!" Alex said. Robin clamped her mouth around the base of his prick anti pulled upward. Her lips left a glistening trail of spit that reflected the light in the room.
"I don't think a cock could ever be too big!" she said from the side of her mouth. "I think I could suck your cock and balls at the same time!"
"Try it," Alex said, his tone eager. "Go ahead, suck all of me!"
She placed the end of his dick between her lips again and slowly sucked downward. His prick seemed to swell to an even greater size than before, but she was determined to give him what he wanted, or die trying.
"Oh God, you've got a mouth like a cunt!" Alex moaned. "So fucking tight and hot!"
She ground her lips around the base of his cock, and with her thumbs, pushed his balls upward. She stretched her lower lip and squeezed the hairy orbs inside her mouth, one at a time.
"Damn! I don't believe you can do it!" Alex said, both amazed and filled with lust.
Robin felt his cockhead burn into her lungs as she forced her head savagely against his crotch. His pubic hairs were at the same time silky and scratchy, and smelled wonderful, like spicy musk. When she moaned, emptying her lungs of air, the vibration of her voice gurgled wetly.
Alex wrapped his left leg around her neck and pulled her even harder into his groin. He humped upward, unable to believe the fantastic warmth of her mouth.
"I don't know if I can hold out much longer!" he said.
Robin, herself, didn't know how much longer she could hold out. His nuts pulsated against her cheeks like boiling golf balls, and his cockhead completely cut off her air. She tried to pull away, but she was no match for his strength or his overpowering desire.
Suddenly a stabbing warmth shot into her chest.
His cockhead swelled to the limit as it began spitting out thick, volcanic-like wads of steaming cum. She inhaled his sperm with a gurgle, thoroughly enjoying the sticky fluid as it oozed downward, into her lungs.
"Drink it, you fucking cocksucker!" Alex groaned. "Suck out my cum and gargle it!"
For a second, he released the pressure of his hands and leg, allowing his sister to breathe. She pulled upward, sucked in a quick gasp of air, letting the exploding balls slip out of her mouth. Then, she sucked his dick back into her throat with an eager, hungry move.
"Aaaaggghhh!" she groaned as her mouth completely filled with burning sperm.
The fluid shot into her body like an electric jolt. As the amount increased, she felt a wild, plunging warmth in the back of her cunt. Then, she felt a torrent of spasms that jerked her pussy walls with convulsing orgasm.
Alex began jabbing his spewing cock brutally between her lips as his pleasure increased. The warmth of her mouth and the spilling gobs of jism that gushed out of her mouth and onto his balls were almost too much to bear.
"Suuuuuucccckkk!" he wailed, jamming his body upward. "Su… suck it, you cumeating cocksucker!!"
Robin gobbled as quickly as possible, but even her eager throat couldn't take it all. Huge masses of sperm collected behind her nostrils and squirted out her nose.
Finally, Alex gave a last, powerful lunge upward, burying the last of his hot load into her lungs. He flinched every muscle in his body for a few seconds, then slowly relaxed.
Robin was oblivious to everything in the world except for three things: her brother's hot, steamy cum, his delicious cock, and the powerful stabs of release that ground into her cunt.
After several long, delicious moments of spasming orgasm, she pulled her mouth upward, releasing his cock.
"God, that tastes so good!" she moaned, her voice greasy and wet with a residue of cum that clung to her throat.
She looked at his prick with a loving expression and kissed it gently. The sperm-smeared shaft throbbed against her mouth with sticky warmth. She squeezed the base of his prick with both hands and slowly pulled upward.
"Look!" she said. "Some more!"
A milky glob of cum squirted out of his cum hole and gently oozed onto his foreskin. Robin lapped her tongue out and pulled the thick mass between her lips. She closed her eyes and moaned passionately as the wad sank into the back of her throat.
"Good!" she gurgled. "I want to suck you forever!"
"You know," Alex said softly, "I honestly believe you could get cum out of a crowbar!"
Robin giggled, then sucked his cock back into her mouth. She cupped his balls and pulled them against her cheeks, eager once again to eat some more of his jism. She knew it would take a little longer this time, but it would be worth it.
"Mmmmmm!" she moaned, bobbing her head up and down, her lips slipping tightly against his shaft. "Mmmmmmm!"
"Christ Almighty, I don't believe you!" Alex said, watching his sister's hunger increase.
It did take a while, but Robin managed to make a believer out of him.
