It was Mandy.
Debby squealed at her sister's intrusion and pulled away from her uncle. There was no problem getting Bob's big prick out of her asshole – his cock had gone soft the moment he realized they were no longer alone in the laundry room.
Dressed in her skimpiest negligee, Mandy kicked the door shut and smiled down, at them with lewd satisfaction. Blushing fiercely, Bob moved his mouth like a frog croaking for air. There was nothing he could say, and all of them knew it. He'd just been caught with his cock deep inside his niece's asshole.
"Well, well, well," Mandy said, putting her hands on her lithe hips. "I thought there was something that woke me up a couple of minutes ago! I'm just glad I decided to come down here and investigate. Uncle Bob! What do you think you're doing with my big sister?"
"I… I… I," Bob stammered.
"You were fucking her up the ass, weren't you?" Mandy interrupted. "Don't try to bullshit me! Debby, you get out of here. I'll deal with you later. Right now I want to have a little talk with our uncle."
Debby, all too eager to leave the embarrassing scene behind her, hurried out of the laundry room to the safety of her bedroom. A knowing smile spread across Mandy's lips. She hopped up on the big white dryer and dangled her slim legs over the edge, staring wickedly at her frightened uncle.
"How long have you been fucking Debby, Uncle Bob?" she asked softly.
"Mandy… please don't do this to me," Bob moaned helplessly. "Don't go and start blabbing about this. Your momma would throw a fit."
"Don't tell me what to do!" Mandy cried impetuously. "Does Debby like fucking you, Uncle Bob? I'll bet she doesn't like it much when you stick that big, fat cock of yours up her asshole! It almost looked like you were raping her!"
"No!" Bob groaned, wincing at the mere mention of the word. "Don't say that!"
"Yes, I will! You were raping her! Boy, wait'll Mom hears about this!"
"Mandy, stop torturing me like this!" Blushing with humiliation, Bob shamefully knelt on the blanket of laundry and looked up submissively at his youngest niece. "You'll ruin me if you say that to your mother. Please, I'll… I'll do anything if you won't tell. Anything at all!"
Mandy's stiff little nipples protruded through the negligee, and her cunt was so hot that it hurt. It turned her on to have such power over her big, muscular uncle.
"I guess there's one thing you might do for me," she said softly.
"What? What's that, Mandy? Anything!"
Giggling, Mandy spread her legs wide apart and planted her heels on the edge of the dryer. Then she scooted her ass to the front of the machine and pulled up her negligee hem to her belly, completely exposing the dark-haired triangle of her juicy, burning cunt.
"You can suck my pussy! Then maybe I'll think about not telling Mom!"
Bob gaped at her in disbelief. He'd always thought that the pert, innocent-looking teen was a virgin. Now it was hard to believe that she wanted his tongue in her pussy.
But she obviously did, and his cock quickly began to swell with fresh blood. Hurrying, before she could change her mind, Bob stood up and crouched in position before the dryer.
Mandy whimpered as he thrust his hands under her hips, cupping the small, rounded cheeks of her ass. Then he dropped his head between her slim legs and moaned with pleasure as he glued his lips to the pouting, curly-haired folds of her fuck slit.
"Unh!" Mandy grimaced and writhed hornily on the dryer, grinding her sopping pussy onto his mouth. "That's good, Uncle Bob! You're a good pussy sucker! Eat out my cunt!"
Bob extended his tongue, dipping it into the fragrant petals of his niece's pussy. Her cunt tasted delicious, as only a young tender, teenaged pussy could.
Soon his prick was as hard as stone, rising out of his cock fur to pulse and jerk against the dryer. Bob re-tightened his hands on her ass cheeks, kneading and massaging the succulent globes. He thrust his tongue deeper into her pussy and feverishly started to eat her out, sliding his tongue quickly up and down her cunt.
"That's good, Uncle Bob! You're making me horneee!" Mandy thrust her hands behind his head and curled her fingers in his hair. Wantonly she started to hump and buck her ass, making the machine shake as she fucked her cunt all over his face. "Suck me! Unh yes, it's making me hot! Lick out my pussy, Uncle Bob! Suck out my pussy good."
Bob's skilled tongue delved deeply into his niece's buttery pussy, exploring the bright pinkness of her fuck tunnel. Mandy gasped as he wriggled his tongue on her swollen clit, tantalizing the sensitive bud.
He pulled one hand from her ass cheeks, unable to hold her humping ass in position. Mandy guided his wrist as he slid it under her negligee and felt up her small, stiff-nippled tits.
"Finger-fuck me! Finger-bang my cunt," Mandy cried. She grabbed his hand and thrust it between her legs. "My pussy's throbbing, it's so fucking hot!"
Pressing two fingers to the fur-fringed lips of her wet cunt slit, Bob buried them to the knuckles in the clasping tunnel of her cunt. He started to pump them in and out hard and fast, finger-fucking her pussy as hard as he could. At the same time he wrapped his lips around her clit and feverishly sucked.
"Cumming, gonna cum!" Mandy's tongue lolled obscenely out of her mouth as her nakedness shuddered with intense desire. "Keep sucking me! Yes, my pussy's sucking on your fingers! Feels so good, Uncle Bob! Cumming, I'm cuuuummmiiinnnnggg!"
The spasms rippled exquisitely through her lithe teenaged body, making her nipples ache and her pussy throb as her cunt hole pumped fresh fuck cream into her uncle's mouth. Bob greedily lapped up every drop of her pussy oil, whipping his tongue in and out of her frothing cunt to clean up the glistening, inner lips of her pussy. His stiff cock throbbed as he tasted her pussy, pulsing stiffly against the machine.
"Now…" He lifted his head, licking stray pussy curls from his mouth, and looked at her meaningfully. "Will you promise not to tell your mother?"
"No! I'm still horny! You're not through yet, Uncle Bob! I want you to suck my asshole."
Bob watched in disbelief as his wanton niece scooted her ass to the very edge of the machine. She lifted her long legs as high as she could and folded her arms under her knees, holding her limbs in position so that her shins nearly touched her ears.
Her pussy slit was wide-open in front of him, dripping cunt juice from the slippery, hairy folds. And so was her asshole.
Bob gasped as he watched the hairless, pink ring throb and pucker obscenely in and out. He'd never put his mouth on a girl's asshole before, but now he discovered that he actually wanted to. His massive cock grew stiffer as he imagined probing his niece's asshole with his tongue.
"Lick it, Uncle Bob!" Mandy cried demandingly. "Lick out my asshole!"
Bob got into position, holding her hips for support. He started to dip his tongue back into her gurgling pussy, but Mandy impatiently pressed his head downward. Bob sighed and touched his tongue tentatively to the tightly muscled ring of her asshole.
"Ungghhh!" A lewd flush spread through the horny girl's face as her asshole started throbbing on his tongue. "Oh, Uncle Bob, lick me down there! It feels so gooood!"
Bob dipped his tongue into her asshole, parting her puckered ring. Her asshole tasted delicious and his cock quickly dripping cum. He squeezed Mandy's hips harder and pushed his tongue fiercely into her ass, gluing his lips to the hairless circle and sucking it hard.
The pressure on Mandy's asshole seemed to excite her enormously, much more than his tongue in her cunt. "Awww, fuck it!" Her face contorted into an obscene grimace. She grabbed the back of his head and wildly humped, her ass, fucking her asshole onto her uncle's lips. "Suck me, Uncle Bob! Suck the shit out of my Goddamn asshole!"
Bob spread her ass cheeks wider apart with his fingers, making her asshole seem to pop out. He sucked it hard, beside himself with the strange, new, forbidden lust. But he only had a chance to suck her ass for a few more seconds before Mandy pushed him away.
"Okay! That's enough!" Whimpering excitedly, the nymphomaniacal teen scooted off the dryer and got into the dog-fucking position on the pile of dirty clothes. "I want to be fucked. I want you to fuck my cunt right now, as hard as you can!"
She dropped her shoulders and lifted her ass, exposing her wet asshole and hairy pussy slit for her uncle's inspection. Bob felt fresh blood pour into his hard-on until his cock was throbbing and as hard as bone.
He knelt on the clothes, between his niece's wide-spread legs and held his cock in his fist, feeling the blood racing through it. Then he centered the cock knob on her hairy pussy slit and pushed inward, lodging the puffy prick in the clasping sheath of her cunt.
"Nnnnggg!" Mandy grimaced as she felt his cock meat going into her, stretching the pouting lips of her pussy around the invading thickness of his cock. "Fuck me, Uncle Bob! Fuck the shit out of my cunt!"
Bob slid his hands up her slim torso under the negligee, cupping her firmly-rounded tits. He started to buck and thrust the hairy cheeks of his ass, ramming his hard-on greasily into her hot, buttery cunt.
Her pussy was very wet and tight, and the pressure of her pussy muscles was as exquisite I as when he fucked his other niece's cunt. Bob clawed her tits and started to fuck into her pussy with a brutal rhythm, pumping inch after inch of his stiff cock into the clinging heat of Mandy's cunt.
"Yes, yes, you're fucking me!" Mandy clawed the clothes and whipped up her ass, wildly pumping her pussy onto her uncle's dick. "Fuck me, Uncle Bob! Your cock feels so good inside my cunt!"
Bob thrust hard, burying his prick to the balls in her tight, clinging pussy. He lay on top of her for several seconds, giving his cock meat a chance to grow used to the sucking pressure of her fuck hole.
Then he started fucking her pussy, reaming out her cunt in long, violent strokes. Mandy gasped and dropped her shoulders lower, opening her pussy passage completely for the stabbing thrusts of her uncle's cock. She humped her ass like a machine, rhythmically pounding her cunt onto his prick.
"Fuck me harder!" she whimpered as she felt her wet, juice-laden pussy tunnel squishing around his cock, clasping and throbbing, trying to suck it deeper into her belly. "Awww, my cunt's burning so good! Keep fucking me, Uncle Bob!"
Bob groaned with pleasure, feeling the tingling stiffness of his aching cock. He caught Mandy's little nipples between his fingers and started to pull on them as he rammed his burning hard-on into the clinging warmth of her pussy.
His cock grew longer and stiffer, and Mandy knew that he was about to cream inside her. Frantically she hammered her ass back to meet his fuck strokes, desperate to have her own cum before he shot her pussy full of jism.
"I'm cumming!" she cried. The familiar heat flowered deep inside her belly, making her pussy contract sharply and her clit tingle as it was chafed by the swollen, pistoning cock. "Keep fucking me, I'm cumming! Unh, Uncle Bob, love your fucking cock! It's doing it to me, I'm cuuuummmiiinnnggg!"
The cum swept through her naked young body, draining her so utterly that she thought she would black out. But Mandy kept humping in a fury of incestuous arousal, banging her pussy up to meet the satisfying stiffness of his long, fat prick.
Her uncle's cock grew even longer and fatter as it bathed in the slippery warmth of her fuck hole, and Mandy could tell he was right on the verge of blowing his wad. Quickly she pulled away from him, falling flat on her belly on the clothes, forcing his cock to slip out of her pussy.
"Goddamn it!" Bob winced as his painfully erect hard-on bobbed and twitched before him. "Mandy, you little teaser! What do I have to do now?"
"You like fucking girls up the ass, don't you, Uncle Bob?" Mandy asked breathlessly. "That's what you were doing to Debby when I came in, wasn't it?"
Bob looked down at her in confusion. Mandy hornily lifted her peach-shaped ass, so that her uncle would be able to see the wet, puckered ring throbbing between her ass cheeks.
"Well, that's the kind of fucking I love best! Stick your big cock up my asshole, Uncle Bob! I want to feel your cum shooting up my ass!"
Bob's massive prick instantly grew stiffer than it had been in years. There was nothing he craved more than sodomy, and he'd never met a girl so anxious to have his cock shoved up her little ass.
Crouching over her nakedness, Bob held his cock in his hand and fit the bloated crown tenderly on to the tightly muscled lips of her asshole. Mandy grunted as he pushed down hard, stabbing the first several inches of his hard-on into the forbidden tightness of her asshole.
"Ungghhh!" Mandy grimaced obscenely as she felt her asshole stretching, forcibly accommodating the steely stiffness of his cock. "Oh yes, fuck me, Uncle Bob!" she cried. "Fuck the shit out of my ass!"
Her asshole was incredibly tight, even tighter than Debby's had been. Bob panted as he furiously cork-screwed his hips, forcing inch after inch of his throbbing hard-on into the rubbery grip of his niece's ass.
Already he could feel her bowel muscles working, sucking and clasping the veined stiffness of his cock. With all of his prick buried in her ass, Bob rested, savoring the pressure of her tight, teenaged asshole around his rock-hard prick.
"Fuck meeee!" Mandy immediately started humping, pumping and grinding her ass onto his cock. "It feels good, Uncle Bob! It doesn't hurt at all! Fuck my asshole as hard as you can!"
Bob pulled out, withdrawing until only the flared knob of his cock pierced her stretched asshole ring. Mandy squealed as her asshole emptied and humped faster than ever. Bob rammed his prick back into her greasy ass tunnel and started ass fucking her, rhythmically pistoning his cock in and out of her eager ass.
"Harder, fuck me harder!" Mandy's squeals were almost loud enough to wake up her parents, but she was too delirious with lust to care. Shamelessly she thrust her hand under her belly, stabbing her fingers into the clasping sheath of her cunt. "Unh unh unh, I'm so horny! Fuck the shit out of me! Fuck my ass!"
Bob panted steadily as he ass-fucked his niece, feeling hit heavy jism-laden balls slap her wet pussy crack with every pounding thrust. "I'm gonna cum, Mandy," he moaned. "Your asshole's so tight and hot!"
"I'm cumming too!" Mandy shrieked. "Fuck me, fuck me as hard as you can. Awww, my asshole's cumming, it's cumming on your fat cock! Haaaarder! I'm cumming, Uncle Bob, I'm cuuummmiiinnnngggg!"
Mandy's little asshole throbbed violently as she came, convulsively sucking and clutching her uncle's prick. Grunting, Bob buried his cock meat to the balls in her ass.
The cum jetted explosively out of his cock head, gushing torrentially into Mandy's asshole. Bob sighed and pistoned his ass, wincing as the salty jism burned repeatedly out of his piss hole. An obscene smile curled Mandy's lips as she felt his cum soothing the ravished walls of her asshole. Wantonly she flexed her ass muscles, sucking out every drop of her uncle's sticky cum.
