"Come on, it was just one time... for now."
"Oh. My. GOD! You total bitch!"
Robert startled awake as his front door slammed shut. His daughters were home, and like usual bickering again. After working all day, all he wanted was to have a nice nap. But such a thing was rare in his battleground of a house between his feuding twins. And this time it was particularly bad. Tracy was the first to stomp into the living room and jab her finger at her sister.
"Daddy!" The long-haired blonde yelled, "Did you hear her? She impersonated me so she could fuck my boyfriend!"
"Come on!" The nearly identical Stacy yowled back, "You did the same exact thing with my last boyfriend, and behind my back too. At least I told you right to your face."
"While you were riding him!" Tracy shrieked. "I know you are not on the pill, and he never wears condoms. Are you trying to make a baby or something?"
"Mmm, trying? Like you and him?" Stacy smirked and cradled her stomach, "Maybe him and I aren't trying anymore, huh...?"
"Daddyyyy!"
Tracy tackled her father's shoulder and buried her face into his neck. There she continued her tirade in so many muffled gasps as Stacy cooed and taunted from across the room. There was no saving his nap anymore. Groaning, Robert rubbed the pleasant sleep from his eyes and glared at the ceiling.
"Girls! Stop yelling. Stop fighting. Right now!"
Robert straightened his babbling daughter up with one arm and scooped in the other with a quick grab around her waist. At once their haughtiness ceased and both took on an absolutely girlish tone.
"Daddy," Tracy said, sweet as a button, "Stacy is a slut."
"Nooo, Daddy!" Stacy began back, "Tracy's a liar AND a sl-"
"Shhh! You're both bad little sluts who've interrupted Daddy's sleep! And did I hear something about a boyfriend?" Robert slapped his hands beneath their skirts and gripped their tight asses. That got through to his horny girls. Tracy squirmed particularly hard.
"He's nobody, Daddy. Just... just a cute boy from school."
"Liar," Stacy smirked, "She's trying to get preggers from him."
"P-preg -- shut up! You were trying the same thing!"
"Well I'm not gonna let you be the first one, like always!"
Like always, Robert's girls shared a remarkable amount of things -- hobbies, boyfriends, fetishes -- but bickered about who got what constantly. They were eighteen years old and still fought like children. They were too old to be bent over his knee anymore, but Robert found a different way to get his cock-hungry daughters to play nice.
"You both know the rules: No boyfriends. Daddy's enough for you both," Robert said. Stacy and Tracy's eyes lit up, though cautious. They had been very naughty after all.
"Are you mad, Daddy?" Tracy asked. "I just... couldn't wait to be a mother."
"Me neither," Stacy whined. Already he could feel his daughter's need moistening their panties. The same went for her sister. Both were starving for cock, and more than just a good fucking. Robert shook his head and began to unclasp his belt.
Daddy's horny girls needed some inbreeding.
"You're both being very bad girls," he said, dropping his belt on the ground beside his chair and unzipping his jeans. "Getting a boyfriend and not even sharing him like good sisters should..."
"We're sorry!" the girls said in unison. Their eyes were fixed on their father's lap as he fished his cock out of his boxers.
"Not good enough, girls. You also interrupted Daddy's nap, so you're going to have to make me feel better about that."
"Yes Daddy!" Stacy was the fastest to drop to her knees and kiss the head of Robert's member. Tracy was close behind, scowling as her sister's lips wrapped around her father's cockhead.
"Tch, greedy slut..." she mumbled, edging her way beneath her sister to kiss her father's balls.
"Muah! That's right, Daddy's mine, just like your boy-mmm!" Robert pulled Stacy hard, bulging her overfilled throat out with every inch of his cock.
"Enough bitching," Robert growled before letting up his wayward daughter.
"D-Daddy, that's mean," The girl coughed and sputtered despite the big smile on her face.
"That's right, Daddy can be mean. Now girls," Robert hooked his hands round both of their necks and pulled them in till their noses brushed either side of his cock. "You're both going to share Daddy's cock and be nice to one another. Understand?"
"Yes, Daddy..." They said.
"Good. Now kiss and make up," Robert pressed his twins' lips against either side of his stiffened cock. Neither of his girls resisted. They worked his shaft immediately, their soft mouths kissing and licking either edge of their father's twitching cock. Their matching blonde hair framed their faces, both close-eyed and reveling in the taste of the thing that helped make them eighteen years ago. And as they both rose to the mushroomed head their lips connected and their tongue wrestled around it.
"Good girls..." Robert petted their lightly bobbing heads. The animosity between them at first fueled their almost violent kissing, as if battling to get more of Daddy's cock into them. But the mirror-match quickly devolved into the sweet, lusty make-out session that only loving sisters could enjoy. Their little mewls and smacking lips and roving tongues turned on their father something fierce.
"Mmmm, now isn't that how you two should always be?"
The girls cast their azure eyes up at him and nodded without pausing their ministrations. They kissed while their father's cock glazed their mouths with spurts of precum that drooled down their chins. It slopped down to their low-cut tops and clung fast to them in sticky strings. They were almost messy enough to coax the cum out of Robert's balls right there. But he couldn't allow that. Reluctant to end their harmonious dick-worship, Robert nonetheless peeled his gasping daughters off.
"Feeling better?" he asked. His girls nodded, their meek smiles and chins dripping with familial juices.
"Daddy, I'm horny... I want a baby," Tracy confessed.
