Chapter 12
"Grease it up real good, Daddy!" Debby cried. "Then ram that huge dick of yours straight up my ass!"
Frank stared hungrily at his naked daughter. She knelt on his bed in the dog-fucking position, with her arms behind her back and her little hands holding the cheeks of her ass wide apart. Frank groaned as he looked at the small, puckered ring of her asshole.
A few days had gone by. They'd fucked constantly since their first session in the study, and now Debby was about to give her father the last hole in her body. It was two in the morning, the perfect time. Kevin, Marsha and Trina had all been asleep since midnight.
Frank unscrewed the cap of the Vaseline container and withdrew a thick hunk of the gooey jelly. He smeared it over his rock-hard cock, knowing that he would soon have every inch of his prick buried in the furnace-like heat of his daughter's asshole.
The he took another hunk of the jelly, and screwed the cap back on, and tossed the jar onto the nightstand. Frank carefully smeared the Vaseline all over his daughter's asshole, making Debby moan as her tightly-muscled ass ring puckered in and out to his touch.
"Oh Daddy, that feels so good!" Debby whispered. "Fuck me now. Please fuck my asshole. I've been waiting for your beautiful cock all night!"
Frank fingerfucked her asshole for several seconds, insuring that the insides of her ass tunnel would be well coated with the jelly. Then he crouched over her naked body, held his pulsing cock in his fist, and pushed the spongy knob onto the pink ring of her asshole.
"Unggghh, yessss," Debby hissed. Immediately she began to hump and buck her asshole onto his cock. "That's good, Daddy! Fuck my ass now! All the way up my ass!"
Frank pushed down hard, inserting the heart-shaped head of his prick into her asshole sphincter. His prick throbbed painfully, and he had to pause for a second as he accustomed himself to the incredibly strong, rubbery pressure of her asshole muscles around his dick.
"Unggghh! Oh fuck me, Daddy! So fucking good! Ungghh! Unhhh!"
Frank slid his hands under his daughter's belly, firmly cupping her big, pendulous tits. Then he began to buck his ass, slowly but surely forcing his cock down into the burning tunnel of her asshole.
Debby whimpered and cried as she felt her asshole being invaded by her dad's enormous cock. He had such a big, thick dick. She could feel every inch of the shaft boring into her, separating the walls of her asshole as they accepted his meaty prick.
"More, Daddy!" she whined. Wantonly she heaved her hips, pumping her asshole onto his cock. "I love it, it's so big! Fuck me with it, all the way!"
Convulsively Frank jerked his hips, burying his prick to the balls in the sucking heat of her asshole. Debby groaned and fell on her stomach on the bed. Frank felt her asshole throbbing as it engulfed his dick.
He pulled up slowly, withdrawing his drooling cock until only the knob parted her stretched anal lips. Even more slowly, he thrust his dick all the way back in again.
At first he fucked her almost gently, smoothly pumping his swollen dick in and out of her asshole. Then his movements became faster, hungrier. Seconds later, Frank was assfucking his daughter as hard as he could.
Debby was in seventh heaven. The heat in her asshole and juice-soaked cunt seemed to merge into one, filling her whole body with an intense, irresistible desire. She'd never felt so filled by a man's cock.
"Make me cum, Daddy!" Clawing the sheets, she humped her ass to meet his thrusts. "Fuck me, fuck me hard, make me cum!"
"Play with yourself," Frank gasped. He squeezed her big tits and pounded his cock up her asshole even harder. "Jack off your cunt!"
Shamelessly, Debby thrust her hand through her curly pussy hairs and buried three fingers in the clasping lips of her fuck hole. Frantically fingerfucking her dripping cunt, she rubbed her clit with her thumb. As soon as she touched it she started to cum.
"I'm there, Daddy!" she moaned ecstatically. "Oh yes, fuck me now! Ungghhh! Daddy, Daddy, fuck my asshole, I'm cummiinng!"
Debby jerked and heaved as the spasms poured through her cunt and asshole. The walls of her rubbery ass tunnel clamped tightly around Frank's dick, and he felt the jism boiling in his swollen nuts. He was just about to blow his wad when he glanced at the bedroom door.
Trina was standing there. She was naked except for a transparent, shorty nightgown, and she was smiling broadly. She'd been watching them the whole time.
"Trina!" Frank gasped breathlessly. "I can ... I don't ... uhhh ... "
Trina cut off her father's mumblings with a knowing, mischievous giggle. Crossing the room, she pulled off her gown and showed her father the stacked beauty of her naked body. Then Frank knew she was as horny as her younger sister.
"You don't have to feel bad, Daddy," she purred. "I don't mind your fucking Debby. Just as long as you fuck me too!"
Trina crouched on the mattress right next to Debby, in the same dog-fucking position. Frank gaped in shock as she spread her thighs and lifted her hips, exposing the hairy mouth of her pussy beneath the cheeks of her ass.
"Come on, Daddy, fuck my cunt!" she cried. "That'll make me nice and hot! Then you can fuck my asshole too!"
"Yeah, Daddy!" Debby said happily, rolling onto her side to make room for them. "Go ahead and fuck her. I want to watch!"
Frank's cock was now as hard as iron pipe, and his balls were painfully swollen with cum. Quickly he crouched behind Trina's body and fit his bloated cockhead into the curly-haired slit of her cunt. Heaving forward, he rammed all of his prick up her pussy.
"Unggghhhh!" Trina grunted as her cunt was suddenly filled with her father's throbbing cock. Then she began to jerk her hips, encouraging him to fuck her. "That feels good, Daddy! Your prick is enormous! Fuck me now! Make my pussy wet!"
Frank started fucking his elder daughter as fast and as hard as he could. The bed creaked on the floor, and a smile spread across Debby's face as he rhythmically pumped his meat into Trina's cunt.
"Harder, Daddy, I like it hard!" Trina shouted. Her huge tits jiggled wildly as she looked at him pleadingly over her shoulder, bucking her ass to meet his driving thrusts. "Fuck my cunt!"
Frank reamed out her pussy a minute longer, panting and sweating as his big cock soaked in the buttery juices of her hairy pussy. Suddenly Trina fell forward onto her belly, forcing him to withdraw his cock from her cunt. Then she grabbed the cheeks of her ass and spread them wide, revealing her aching asshole.
"Okay, Daddy, I'm ready now!" she cried excitedly. "Go ahead and ram it up my ass!"
Frank centered the tip of his burning, twitching cock in the rubbery ring of Trina's asshole. He pushed down hard, burying over half of his prick up her ass with one thrust.
"Unggghhh!" Trina grunted and bit her lip as her asshole stretched around his invading dick. It was painful to take such a huge cock, but any discomfort she felt was overshadowed by a deep-seated, insistently pulsing pleasure. She knew she was going to cum harder with her father than ever before in her life.
Frank slid his hands around her rib cage and greedily cupped her large, stiff-nippled tits. Then he violently bucked and humped over her, forcibly pounding more and more of his cock up her asshole.
"Oooooh, Daddy!" Trina cried. Shamelessly she began to heave beneath him, lifting her asshole up for more of his dick. "Oh yes, it really feels good now! Give me more of it! I want all of your prick!"
Then Frank had all of his cock buried in the clinging, pulsing wetness of Trina's asshole. He started to fuck her savagely, making her reddened ass cheeks jiggle as he hammered his dick in and out of her stretched asshole ring.
"Nnnngggg, oh Daddy, fuck my ass!" Trina gasped. She thrust her hand under her belly and wantonly fingerfucked her pussy as he reamed her asshole, flicking her clit with her thumb. "So good, so big and good! Unhhh! I'm gonna cum, Daddy! I can feel it already!"
Frank was going to cum too. His prick was so stiff he thought it would burst, and his balls were packed with his cum. Moaning, giving in to the pleasure, he rammed his cock up his daughter's asshole until his nuts touched the cheeks of her ass.
The white cum burned out of his dickhead, filling Trina's asshole with one hot spurt after another. His jism filled her ravaged asshole completely, burbling out of the ring around his cock and dripping onto the bed. Frank fucked her fast and hard until all of the cum had drained from his balls.
"I'm cumming, Daddy!" Trina shrieked. She humped and bucked and stroked her pussy like a bitch in heat as the spasms shot simultaneously through her pussy and asshole. "Awwww, fuck me Daddy, fuck my asshole! Ohh! Oh, Christ!"
Trina came so hard she nearly blacked out. Dots of color danced before her eyes as the force of her climax made her asshole throb and drenched her pussy with juice. Moaning with satisfaction, Trina collapsed in a sweaty heap on the bed. She'd fucked many of the patients in the hospital, and she'd fucked her brother too. But none of them could ever compare with her daddy.
