It was after midnight and Mandy lay sleeplessly next to her sister, staring at the ceiling and rubbing her thighs together to massage her ever-horny cunt. Tomorrow she had a big quiz in history, and she couldn't sluff off in chemistry class, either, or Mr. Wrenn was going to give her a big demerit.
She needed her rest, but there was no way she could get to sleep feeling so horny. She and Debby had sucked each other off, as usual, but Debby's heart didn't seem to be in it anymore, and besides, there was no way another girl could satisfy the lust Mandy felt now. Mandy was sure she was going to go mad unless she felt a big cock piercing her little ass and fast!
She wanted her brother to do it to her, to stretch her horny little asshole with his big, stiff cock. Impulsively, Mandy rose from the bed and padded barefoot and naked out of the bedroom. She didn't care if Johnny was sleeping. She was going to get what she wanted right now.
Tip-toeing down the stairs, Mandy went first into her parents' bedroom. As quietly as possible she opened the medicine cabinet and looked inside. Next to the usual assortment of aspirin bottles and vitamins was a small plastic jar called "Lover's Lube". Mandy had first seen it there a long time ago, while snooping through her parents' bedroom. Now she was anxious to put it to use.
Withdrawing the jar, she shut the medicine cabinet and left the bedroom as quietly as possible. Then she skipped up the stairs and opened her brother's bedroom door.
He lay sleeping on his back under the covers, dead to the world. Mandy closed the door behind her and padded across the room. Sitting on the edge of the bed beside him, she flicked on the lamp next to the bed.
Johnny was apparently very tired, because he didn't stir at all. Mandy's fingers trembled with desire as she took the covers in her hands and pushed them down his body to the foot of the bed.
He always slept naked, and her pussy burned at the sight of his leanly muscled body. But more than anything else, she was entranced by his cock. It lay across his hairy upper thigh, rubbery and half-stiff. Even in a semi-soft condition her big brother's prick looked enormous to her. Mandy couldn't wait until she felt his huge cock boring into her ass.
Sliding her hand down his tightly muscled stomach, the naked brunette hefted his cock and squeezed it gently. Immediately her big brother's prick began to stiffen and swell with blood. Mandy sighed and squeezed his prick harder, and soon his cock was as hard as stone.
She took her hand away and stared at his cock. It rose straight out of his cock fur in in a semi-crescent over his stomach. Her brother's eyes were tightly shut, but his prick rhythmically throbbed and pulsed. Clear juice dripped from the slit in his cock knob.
"Oh, fuck, I'm horny," Mandy whispered. She pinched the base of his prick between her fingers and extended her tongue, getting her very first taste of cock. It was delicious! Mandy's pussy burned and her asshole throbbed as she licked all around the heartshaped crown of his hard-on, pressing her tongue into the piss hole to lap up his dripping juices.
"Unh!" Johnny stirred and sighed in his sleep, but he didn't open his eyes. His slumbering lips curled into a lewd smile as his sister kissed and licked all over his cock.
With trembling hands Mandy unscrewed the top of the jar of Lover's Lube. She held up the jar and sniffed – a faint scent of strawberry.
Withdrawing a hunk of the gel on her fingers, she smeared it liberally all over her brother's bone-hard cock.
The lube made it easy to move her hand on his prick, she discovered as she wrapped her hand tightly around his stiff cock. Her fist made a sound like beating cake batter as she rhythmically began to stroke and jack his aching prick, pumping her fist rhythmically up and down the swollen shaft.
Then Johnny opened his eyes.
"Unh…" He shook his head hard to clear the cobwebs from his eyes, then gaped disbelievingly at the sight of Mandy beating his meat. "Mandy! What the fuck are you doing in here?"
"I'm going to give you a blow-job, dear Brother," Mandy replied huskily. "But first I want to get your prick nice and juicy with this sweet stuff, so it tastes super-good in my mouth!"
She withdrew another hunk of the flavored gel and smeared it all over his cock, until the throbbing stalk was completely coated in a glistening sheen of the cream. Then Mandy slid her fist to the root of his hard-on and she took his cock between her lips.
The gel had tasted good on its own, but it had apparently been formulated to mix with the musky secretions produced in a man's loins and the combination was absolutely delicious! Whimpering pleasurably, Mandy tightened her lips around his cock. Then she started sucking her brother's prick furiously, puckering her cheeks to increase the suctioning pressure around his big prick.
"Unh, fuck!" Johnny started to sit up, as if he were about to push his sister's head off of his prick. But then the pleasure of her wet cock-sucking started to get to him.
"Oh, Christ…" He let his head fall to the pillow, wincing as his horny baby sister delivered a particularly hungry suck to his throbbing hard-on. "Do it, Mandy!" Giving in, he curled his fingers into her short, brown hair. Then he started to buck and hump his ass off the bed, fucking his cock into her mouth. "That's a good girl! Give me some head!"
As she slurped contentedly on his raging cock Mandy wondered if she would love giving head as much as she craved a stiff cock probing her asshole. Her brother's, prick was so fat and stiff, and it tasted so good in her mouth. Mandy desperately needed to feel his meaty thickness punching into her asshole, but she also craved the taste of his hot cum.
Swirling her tongue all over the shiny skinned knob of his cock, Mandy darted it into her brother's piss hole and lapped up the cock juices dribbling up from his swollen nuts. Then she re-tightened her fist around his cock shaft and started to jack him off as she sucked.
The tasty jelly made her hand move easily up and down his hardened prick. Mandy stretched her lips and made lewd slurping sounds as her mouth completely engulfed his cock. Her wrist whipped up and down in a blur, beating her brother's cock meat.
"Shit!" Johnny's expression contorted as he watched his young sister blowing off his cock. He observed the flush in her cheeks and the way her lips were stretched to bursting around his massively swollen prick. "That feels good, Mandy! Unh, fuck, keep sucking me! I'm gonna fill your mouth with cum!"
Noisily Mandy slurped and gurgled and licked and sucked, falling in a trance over the big, tasty cock in her mouth. She pushed her left hand between her thighs and finger-fucked her pussy for a moment, whipping her cunt into a frothing swamp of lust.
Then she put her fingers into her asshole, stretching the puckered ring for the impending invasion of her first cock. Finally, she pushed her left hand between Johnny's thighs and dug her fingers into the hairy sac of his balls.
"Oh shit, that's what I need!" Johnny bucked his ass furiously off the mattress, fucking his burning cockrod in and out of his sister's sucking mouth. "Play with my balls, Mandy! Keep jacking off my prick! Oh God, my cock's burning! I gotta spurt!"
Clenching her fingers into his ball bag, Mandy jacked and sucked his hard-on as hard as she could. Her brother's prick swelled between her lips until it was so stiff that she thought the skin would tear off his prick. Then he started to cum.
A white stream of jism opened his cum slit, spurting torrentially down her throat. Mandy tasted it as it shot across her tongue and moaned in ecstasy. Her brother's spunk was very, very good!
Hotly she worked her throat muscles, rhythmically pumping her fist on his spurting cock to milk out all of his cream. Johnny moaned and writhed on the bed as the salty jism continued to gush out of his prick. Mandy hornily drank it all down, refusing to release his cock until she'd sucked every last drop from the tip of his throbbing prick.
"Oh shit, Sis!" Johnny smiled luridly as tingling sensations of pleasure continued to course through his cockmeat. "You can wake me up to suck me off any time you want! That was the best blow-job I ever had in my life!"
"But now it's my turn, Johnny!" Hornily Mandy continued to stroke and jack her brother's cock as she spoke. "This time I want you to fuck my asshole. But first you have to lick my pussy, till your cock gets hard again!"
Mandy climbed up on the bed and straddled his face, digging her knees onto the mattress to either side of his ears. Then, she lowered her quivering ass and ground her pussy onto his mouth.
Her cunt was very hairy for a young girl, and the thick fur fringing her pouting pussy slit was matted with the fuck juices dripping from her cunt. Johnny extended his tongue and delved into the flowering folds of her fuck hole, tasting the cream that flowed from her throbbing pussy.
Immediately his cock started to swell with fresh blood. Mandy shuddered as she felt her brother's strong hands sliding up her thighs and cupping the cheeks of her ass. He pushed his tongue back into her cunt slit and hungrily ate her out, burrowing deep between the swollen lips of her pussy.
"Yes, Johnny, that's so fucking good!" Uncontrollably Mandy humped her little ass, thrusting and grinding her wet fuck hole onto his mouth. "Suck me off good, Johnny! Unh unh, lick my clitty! Then you can fuck my ass!"
Squeezing her ass cheeks, Johnny whipped his tongue up and down her steaming pussy furrow, lapping up the cunt cream that boiled out of her hairy pussy. Mandy whined as his tongue circled her stiff clit, massaging the tip of the ultra-sensitive bud.
"Suck it, Johnny!" She humped her ass in a fever, fucking her wet pussy all over his face. "My cunt's so fucking hot, it hurts me! Eat me, eat me out! I need to cum!"
Johnny's cock was already as hard as stone from the taste of his sisters pussy, and he was anxious to ram it up her asshole. He glued his lips to her clit and sucked it hard, as if trying to gently tug it out of its roots.
Mandy shrieked and fucked his face faster. Panting through his nostrils for air, Johnny released her bucking ass and pushed his fingers into her pussy, stretching her little cunt. He started to get her off as he sucked on her clit, pursing his lips tightly around the swollen button.
"Cumming, Johnny! Suck my cunt!" Mandy pulled his hair and bucked her ass in a frenzy, feeling her pussy juice and her asshole throb as the spasms gushed through her naked, teenaged body. "I'm cumming, Johnny! Eat out my pussy, I'm cuummmiiinnnggg!"
The spasms swept exquisitely through her pussy, making her clit throb and her pussy gush fuck oil onto her brother's mouth. Johnny buried his fingers into her slippery, cumming pussy and lapped it all up. Then he gently continued to kiss and lick her pussy after her cum had subsided, cleaning the wetness off of the glistening petals of her cunt.
Mandy wanted him to suck her pussy some more, but her asshole was hot and ached for a good fuck. Climbing off of him, the horny teen crawled quickly into the dog-fucking position. She wiggled her ass and looked at him expectantly over her shoulder.
"You've got another hard-on, Johnny!" she squealed. "Come fuck me with it now! Your cock's wet enough! Put some of that jelly on my asshole!"
With his stiff cock twitching and jerking before him, Johnny grabbed the jar of lotion and withdrew a thick hunk of it on his fingers. Mandy whimpered and flexed her asshole as he smeared it all over her puckered ass ring.
Then, with both her asshole and his cock thoroughly coated, he replaced his finger with the head of his cock. At the first thrust of his hard-on, Mandy fell flat on her belly on the bed. Then she simply lay there and moaned as her big brother gradually stuffed her virgin little asshole full of his big prick.
"Yes, Johnny, yes!" For Mandy it was like a dream come true, like having all of her most forbidden fantasies realized in thrust after thrust of her brother's fat cock. Her asshole was stretching exquisitely, sucking and clasping around the inches of his prick as he buried them between her ass cheeks.
She'd always wanted to have her asshole fucked, even more than she'd craved a stiff hard-on in her pussy. And now it was finally happening to her, and it felt even better than in her fantasies.
"Fuck my asshole, Johnny!" With half of his cock embedded in her rubbery asshole, Mandy eagerly began to pump and grind off the bed. "Yes, yes, fuck the shit out of me! It doesn't hurt at all, it feels so fucking good! Fuck my ass, fuck me good!"
Johnny cork-screwed his hips, forcing every inch of his stiff cock into the furnace-like heat of his sister's asshole. For a long time he simply lay on top of her sweating nakedness, gasping as he felt the pressure of her throbbing asshole around his cock.
"Fuck me!" Mandy thrust her fingers under her belly, burying two in her sopping wet pussy. Hornily she started to get off as she flexed her asshole, making the rubbery tunnel suck and clasp tightly around her brother's big cock. "It feels so good! I'm gonna cum again, Johnny! Fuck my ass as hard as you can!"
Johnny pulled out, withdrawing his greasy, jelly-slicked prick until only the knob parted his baby sister's ass lips. With a heavy thrust he pounded it back in again.
It was so tight and wet in there, milking him better than the sweetest pussy he'd ever fucked. Johnny winced as he sawed his cock into her asshole again, and again, feeling the second load of jism boiling in his heavy balls.
Then he fell into a steady fucking rhythm, hammering his bloated cock relentlessly between her jiggling, red-blushing ass cheeks. Crying and whimpering, Mandy thrust her fingers in her pussy and hopped up her ass to meet his strokes.
"Harder, Johnny!" She flexed her asshole continually, uncontrollably, repeatedly making the narrow shit tunnel pressurize her brother's pistoning prick. "Fuck me, fuck me good! I want all of your cock, it's making me cum!"
Johnny panted and started to fuck her asshole as hard as he could, making the bed shake as he rammed his rock-hard prick into the churning heat of his sister's asshole. Parting her jiggling ass cheeks with his hands, he watched her pink-muscled, wide-stretched ass clutch the hammering shaft of his cock, convulsively milking it deep into her belly.
"Keep fucking me, Johnny!" Mandy grimaced as she rammed her fingers feverishly into her burning pussy, wildly rubbing her clit under her thumb. "My asshole's throbbing, it's throbbing on your cock! Unh, Jesus, you're making me cream!"
Suddenly a delicious shudder shot through her nakedness, and Mandy stiffened from head to toe. The pleasure was now more intense than any she'd felt in her life. The throbbing heat in her asshole seemed to spread through her whole body, making her pussy clutch her fingers and her asshole suck his cock.
"Cummmming, Johnny!" Mandy bucked and humped as hard as she could, pounding her ass up for more of her brother's prick. "Fuck me, fuck my asshole! It's so hot! I'm cuuuummmiiinnnnggggg!"
Johnny sighed as his baby sister's asshole contracted spasmodically around his aching cock. He pistoned his cock into her ass, ramming it to the hilt between her ass cheeks.
The white cum load spouted up from his balls, gushing torrentially into his sister's asshole. Mandy felt the soothing rush of his jism and wantonly flexed her asshole muscles, helping her brother dump all of his cock juice into her ass.
Mandy smiled in shameless ecstasy as the last cum drops oozed out of the head of his cock. Never in her life had she felt so satisfied, and now she had a big cock ready to give her asshole a good fucking, whenever she wanted it!
