Pastor James sits at his desk in his study. My entire life is coming apart. He suspects his wife, Sally, is cheating on him. His twin daughters, nineteen-year-old Kylie, and Kayla, no longer attend church since attending the local college. That, and their piercings and tattoos are repulsive to him, not to mention those disgusting boyfriends and girlfriends of theirs. He has hope for his son, Tommy, eighteen, a senior in high school who does not get caught up in the numerous transient fads and is more interested in sports than anything else.
He strokes his shaved head then twirls his full beard as he opens his father’s Bible. I’m losing my congregation, too. The megachurches have so much money and glitz. Fucking Hollywood. Sorry, Lord. Please help me save my family and inspire my congregation. He looks around his study at all the different Bibles and commentaries. The interlinear Greek and Hebrew. Versions. For what? He puts his head in his hands and closes his eyes.
His phone buzzes. He picks it up and clicks on the notification bubble: Congratulations! You have the opportunity right now to participate with your family for an ‘I’ gamma testing! Do you accept? Yes or No. He shrugs and presses ‘yes’. Another bubble appears. Wise choice, James. The download is complete.
I hope I didn’t screw up my phone. He hears a buzzing and looks for a fly. His father’s Bible appears to glow and he opens it feeling a throbbing sense of power moving through his being. He flips the Bible open at random and the injunctions against incest in Leviticus glow with a preternatural light. He flips it again and it opens to the story of Lot and his daughters.
He hears the sound of his daughters’ car pulling into the driveway, he smiles, driven by a powerful force beyond his control. He exits his study and strides down the hall to the spacious kitchen. He pulls out some ice cream and gets the blender.
The girls enter the kitchen and look at him, trying to determine whether he’ll talk about their multi-colored hair and partially shaved heads.
“I’m making some milkshakes, would you like one?” he says, noticing how short their skirts are.
“Yeah, Dad,” they say in unison, looking at each other with some surprise, expecting him to criticize their latest appearance. h
“I’ll call you when they’re ready,” he smiles.
“Okay,” Kylie says.
“Is his voice deeper?” Kayla asks as they leave the kitchen to go to their basement bedroom.
“Yeah, like he’s on something,” Kylie smiles. “Can you imagine Dad doing drugs?”
They both laugh, entering the dimly lit emo/goth-decorated room, and tossing their backpacks on the floor.
James blends the ingredients, his cock throbbing preternaturally hard and swollen. He opens the zipper on his khakis and hauls out his distended member. He removes the pitcher and holds it with one hand while jerking himself off with the other. He grimaces and pants as his turgid shaft swells and throbs with power. Seconds later streams of viscous fluid splatter inside the pitcher making the milkshake cream ripple from the impact of his ejaculate.
He chuckles as he pours it into the fluted stem glasses, putting the pitcher in the freezer. He sprays whipped cream on it and a maraschino cherry on top. He gets the milkshake spoons and puts them in the glasses. He carries it downstairs to their bedroom and calls, “Your milkshakes are ready, girls.”
“Thanks, Dad,” Kylie says, exiting her room. “Wow, you went all out.”
“Yeah, thanks, Dad,” Kayla says, taking hers.
“I put a new ingredient in this batch. I’m curious to see if you like it,” he smiles, standing in the doorway, watching them as they sit on the edge of their beds eating. He hears a mocking laughter in his head as they consume the cold treat.
“Do you like it?” he asks.
“Oh. my God, Daddy,” Kylie says. “This is the best shake I’ve ever had.”
“What did you put in here?” Kayla asks. “I don’t like eating frozen desserts fast because I get brain freeze but this is so good!”
James chuckles watching them gulp down the shake so fast they both have milkshake mustaches. Even in the dim light, he can see their faces flush, their pupils dilated. “So you both like my shakes?”
“Yes, Daddy,” they say in unison, squirming their bottoms on the bed.
“Would you like to experience what the secret ingredient is?” He chuckles, watching them slurp the last of their shake.
“Are you sure?’ He growls their eyes burning on the prodigious bulge on his khakis.
“Yes, Daddy. Please,” Kylie pants.
“Please, Daddy,” Kayla moans.
“Do you girls like it?” he asks. Stepping toward them, watching them squirm more, licking their lips.
The girls watch in wonder as their father unzips his pants. His massive cock juts out, throbbing with power and vitality.
“Please, Daddy,” Kayla gasps. “I-I want to touch it.”
“I wanna suck it, Daddy!” Kylie says, sliding off the bed, getting on her knees as she begins edging it, her eyes looking up at James with animal hunger.
“I want Daddy’s cock, too, bitch!” Kayla says, dropping next to her twin, edging the meaty cock with gusto.
“Praise the Lord of incest,” James growls. “Praise him!”
“Praise Him,” the twins say in unison.
“Strip naked before me, I’m going to baptize you with my cum,” he orders.
“Yes, Daddy,” they say, getting to their feet, undressing as he undresses, their eyes unwavering on his throbbing veiny cock.
“Now worship your lord and master,” he groans, his eyes devouring the lusciousness of his gorgeous teen daughters.
Both girls drop to their knees, worshipping his meaty cock and heavy balls with fingers, mouths, and tongues as they moan and hum along his cock and balls.
“Prepare for baptism,” he growls, jerking himself off as they kneel and open their mouths, sticking out their tongues, watching him masturbate with fury.
“Do it, Daddy,” Kylie sobs, squeezing her tits. “Baptize your slutty daughters!”
“Yeah, Daddy! Show us the true path,” Kayla moans, pulling her nipples.
James grunts and gasps as he tugs, stream after stream of daddy jizz spraying out of the small slit, splattering and splashing incest cum all over the twins’ faces and tits. He steps closer and discharges into their open mouths, making their eyes roll up as they squeal and climax without being touched.
James lifts Kylie by her armpits and tosses her on the bed, making her squeal with anticipation. He grabs Kayla and tosses her next to her sister.
“Please fuck me, Daddy,” Kylie whines.
“Fuck me first, Daddy,” Kayla pleads.
“Get on all fours, Kylie,” James orders. “Kayla! Straddle over your sister so I can tongue fuck your pussy!”
The girls do as they are told.
Kylie squeals as James shoves his swollen cock inside her teen pussy, stretching her to pleasure fulfillment “Oh, Daddy! That’s so fucking good,” she sobs, grinding against the paternal prick.
“Oh, my fucking God!” Kayla moans as James shoves his tongue inside her wet pussy. “Daddy’s got a tongue like a fucking serpent!”
