Chapter 12
"Keep fucking me, Daddy!" Helen cried. "Ungghh! Your cock feels so good! I'm gonna cum soon! Fuck me as hard as you can!"
They were in the doggie position now, fucking their brains out on Helen's bed. Naked, Helen squatted on her hands and knees, with her head down and her ass upraised so her father could best pack his cock into her pussy. Bill knelt behind her, squeezing her big tits as he hammered his drooling, throbbing cock through the depths of her teenage cunt.
"I can't hold back much longer," Bill said. He winced as he felt the pressure of her pussy muscles milking his prick. "Jesus, is your cunt tight! I'm gonna blow my wad any second!"
"Fuck meeeeeeeeee, Daddy!" Helen moaned incessantly. She humped her ass with the energy of her youth, thrusting her cunt onto her father's horse cock. "I'm gonna cum too! Fuck me hard!"
Holding back for his daughter's benefit, Bill kept slamming his long cock in and out of her gaping pussy. Helen kept her head down and let her father work off his rocks in her clinging cunt.
A week had passed, and her father's back was completely healed. Ordinarily it took him longer than that to fully recuperate from a sprain, but Helen suspected that all the fucking and sucking had a beneficial effect on his spine.
They'd been at each other constantly, twenty-four hours a day. Neither of them was getting enough sleep. They were too busy making each other cum. Even Roger's fucking skills paled next to her father's. Helen didn't think she'd ever want another man again.
Suddenly she felt the familiar, tingling heat flowing deep inside her pussy, and Helen knew she was on the verge of another climax. Clawing the mattress, she pounded her jiggling ass cheeks back as fast as she could, whimpering as Bill's cum-bloated cock totally filled her dripping pussy.
"Cumming, Daddy!" she shouted. "Unggghh! Oh, shit, I feel it now! Fuck me harder! Harder, harder, awwww, I'm cummmiiinnnggg!"
The explosive force ripped through her pussy, making her clit tingle and drenching her fuck-hole with juice. Bill held the cum in his balls and kept fucking his daughter. He was still fucking her when the last spasms shot through her cunt.
Suddenly, Helen had an exciting idea. Her father and she had sucked each other off, and fucked in every imaginable position, but so far he'd never tried to cram his gigantic prick into her asshole. They'd both guessed her little asshole was too small for his cock. But Helen felt extremely horny, and she wanted to try.
"Take it out, Daddy!" she squealed, remaining in the dog-fucking position. "I want you to fuck me in the asshole."
Bill pulled his rock-hard cock out of her pussy and looked at her worriedly. "You're kind of young for that, honey. I don't think it will fit."
The more Helen thought about it, the more her asshole burned at the thought of being invaded by her dad's cock. "Come on!" she said eagerly. "You can do it! The Vaseline's right next to the bed! Just rub on a whole bunch of it!"
Bill hesitated, but the sight of his daughter's pink, puckered little asshole changed his mind. Reaching over to the nightstand, he opened the drawer and withdrew the small container of petroleum jelly.
Helen wiggled her ass, horny with anticipation. Unscrewing the lid, Bill took a thick hunk of the jelly on his fingers and smeared it liberally on his cock, coating the throbbing shaft from knob to base. Then he took another hunk for his daughter's asshole.
"Oooooooooh, Daddy!" Helen whimpered. She stretched her arms behind her and pulled her ass-cheeks apart, baring her asshole, sighing as her father coated the tightly-muscled ring with Vaseline. "That feels good! Get inside, too!"
Bill thrust his jellied finger into her asshole, coating the inner walls of her ass tunnel. Helen shivered hotly and spread her ass cheeks wider. Replacing the jar on the nightstand, Bill hunched over his daughter's nakedness with his huge prick throbbing violently in his fist.
"Are you ready for it, honey?" he asked hoarsely.
"Fuck me, Daddy! Stick it up my ass!"
Carefully, Bill fit the knob of his cock on the center of her asshole. He pushed down gently and watched Helen's asshole open to admit the spongy crown of his cock.
Helen felt like she was being fucked by an elephant. She could feel her puckered shitter stretching to the bursting point, reluctantly giving way to admit her dad's enormous hard-on.
There was some pain as her asshole walls tore, and she could feel herself bleeding slightly. But Helen was determined to withstand it. Whimpering girlishly, she dug her fingernails into her rounded ass cheeks and prepared herself for the full invasion of her dad's cock.
"Is it okay, darling?" Bill asked breathlessly. The first three inches of his prick were embedded in her butt-hole. He moaned as he felt her rubbery asshole sucking tightly around his prick. "Oh, God, that feels so fucking good! Can you take it all?"
"Fuck me!" Helen demanded bravely. "Ram it up my ass!"
Bill took a deep breath and changed his position so his ten-inch cock would angle directly toward the center of her asshole. Then he started bucking his hips, gradually forcing inch after inch of his throbbing hard-on into the vise-like grip of her asshole.
"Unggghhh!" Helen started humping her ass in unison with her father's thrusts. "It's starting to feel good, Daddy! Ummmm! Oh, Jesus, it doesn't hurt at all any more! Give me more of it, Daddy! All of your prick up my ass!"
Bill slid his hands around his daughter's ribcage, lustfully clasping her big, pendulous tits. Then he delivered a final, savage thrust, sinking his cock to the balls in the ravaged ring of her asshole.
Helen didn't know if she could take it. Ten inches of rock-hard cock were embedded in her little asshole. She'd never before felt so totally filled by a man's prick.
Then the throbbing pleasure grew suddenly more intense, and Helen realized how badly she wanted her father to fuck her ass hard and fast. She started humping again, eagerly lifting her plump ass cheeks for the pistoning thrusts of his cock.
"Do it, Daddy!" she cried. Clawing the sheets, she sweated and grunted shamelessly with desire. "Fuck my asshole! Do it hard!"
Bill pulled his cum-drooling prick out of her asshole, until only the fat knob parted her puckered ring. Helen whimpered loudly as he plowed his cock all the way up her butt-hole again.
"Fuck me, Daddy! Fuck meeeee ..."
Bill started fucking her, reaming out her asshole with long, violent strokes of his blood-engorged cock. Helen felt his hands tightening around her tits, and his bloated balls slapping the crack of her blushing ass with every thrust.
"Harder, Daddy!" Helen shrieked, delirious with pleasure. She thrust her hands under her belly and searched for her pussy slit with her fingers. "Unhhh! Oh, God, you're making me cum! I love having my asshole fucked! Do it as hard as you can!"
Bill winced as the jism churned in his balls, making his enormous prick as hard as iron. He started fucking his daughter's asshole with a savage intensity, making the bed shake as he filled her stretched, rubbery ring deeper with every thrust.
"Unggghhh, Daddy!" Frantically Helen jacked off, rubbing her swollen clit with her thumb as she pumped her fingers in and out of her gurgling cunt. "I'm cumming now! Oh, Daddy, your cock is so fucking big! Fuck me, unh, unh, fuck my asshole! Awww, Daddy, I'm cummmiiinnnggg!"
It was one of the best orgasms she'd ever experienced in her life. For what felt like minutes, the spasms shot through her cunt and asshole, making her clit tingle, her pussy gush, and her asshole pucker and cling to her father's pumping cock.
Bill realized that he didn't have to hold back any longer. He delivered a few final, pile-driving thrusts, then pounded his cock to the root in his daughter's burning asshole. Already the cum had begun to shoot from the pink crown of his cock.
It spurted and shot and gushed out of his throbbing prick, deluging his daughter's asshole with so much jism that it ran out of her little butt-hole and dripped down her thighs.
Helen squealed delightedly as she felt the rush of her dad's cum. Wantonly she flexed her asshole muscles, coaxing the last drops of jism from the knob of her father's huge, ten-inch cock.
