"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.
