Chapter Text

“Alvin! Oh…” Dave bolted himself upright. The nightmare faded from his consciousness. He couldn’t remember what happened. Something Alvin did… or didn’t do? He rested his head on his palm as he thought. Alvin had been strangely well-behaved over the past month. There was that broken gaming headset and a few bratty shouts as per the norm but no real incidents. No property damage, no disastrous get-rich-quick schemes. Dave felt grateful for this seemingly miraculous change in behavior - his bank account was also grateful - but something still felt strange. Like the calm before a storm. He couldn’t shake the feeling that he was soon going to discover something he could never have predicted.

“Good morning, Dave!” The bedroom door burst open, making him jump. Theodore walked in with a tray of breakfast. Eggs Benedict and french toast complete with a glass of milk and a steaming mug of Dave’s favorite coffee.

Dave sighed. “Goodness, Theodore,”  he said, wiping the sweat from his brow. “You gave me such a… um… that’s an, uh, interesting outfit you’re wearing.” He looked up and down at Theodore and his eyes opened wide.

The little chipmunk boy wore a black-and-white satin dress with a white bow at his waist. At the top of his head were black cat ears, the base lined with folded white silk. He wore black, fingerless gloves, as well as long white stockings that ran from halfway down his thighs all the way to the set of black maid slippers adorning his feet. Completing the outfit was a black satin band that laced around one of his thick thighs. Dave didn’t know whether to laugh or blush.

“Oh, do you like it?” said Theodore. He turned and revealed tight, white underwear that perfectly hugged his bulging ass cheeks, a green letter “T” stitched into the top just under the elastic waistband. “I’m seeing how it fits because I wanted to surprise Simon with it for his birthday. I feel like the skirt is a little too small… do you think it makes my butt look too big?”

Dave’s face was bright red. He took a bite of his french toast. “ Ahem , uh, I think it… looks good on you.” Must be a phase… thought Dave. Could this be Theodore coming out? I always knew he was more effeminate than his brothers. He’s only eleven, though… maybe that’s when signs start showing? Our neighbor, Judd, did say his 15-year-old started showing signs as early as nine. Hmmm… “S-speaking of Simon’s birthday, I’m gonna finish eating this and then go out to grab supplies for the party. I just need you and Alvin to distract him for a few hours. Think you can do that?”

Theodore turned back around and smiled. “Of course!” He turned around and walked back out, leaving Dave to finish his breakfast. As he walked through the door, his hips swayed to the left and right, the back of the skirt bouncing off his backside, revealing the curvature of his furry buttocks. Dave shook his head and kept eating, ignoring his morning wood, which was normally gone by now.

***

Theodore looked out the window, still dressed in his maid outfit, and watched Dave back out of the driveway. As soon as Dave’s car was out of sight, Theo felt a hard smack to his ass that made the cheeks jiggle. Theo squealed, his cheeks reddening. He turned and glared at Alvin.

“W-why did you - mmmph~!” Alvin’s lips interrupted Theo’s yell. Alvin wrapped his arms around Theo’s waist and pulled him in, kissing him hard on the mouth. Theodore shivered, his hands close to his chest. His cheeks reddened. “Alvin… wait…”

Alvin stopped and pulled away slowly, a thin line of saliva connecting his lips to Theo’s. “What do you mean, ‘wait’? Dave’s gone and Simon’s busy. You know how horny I am.”

“Ok, but you need to help me get the food ready. You do remember it’s a very special person’s 13th birthday today, right?”

Alvin scratched his head. “Hmmm… drawing a blank, here.”

Theo put his hands on his wide hips and scowled. “Alvin!”

“Haha, I’m just teasing!” Alvin thumbed his nose. “I know it’s Simon’s birthday. The big one-three, hehe.” He rubbed his hands together. “That means he’s a real man, now~”

“Hmmm…” Theo put his finger on his chin. “Isn’t that a Jewish thing?”

“I guess,” said Alvin. “Anyway, let’s hurry up and get the cooking done so I can fuck you before Simon’s ready.”

Theo narrowed his eyes. “Alvin, the cooking’s gonna be all day. There’s a lot to do. Plus the decorations. When Dave gets back you’re gonna need to help me put them up.”

Alvin groaned. “Oh, man. Well, then can I just nut in you real fast before we start all that? Come on, I’m horny!” Alvin whined.

“But, you’re always horny,” said Theo. “Here.” He grabbed a feather duster and waved it in Alvin’s face. The look and attitude made Alvin blush harder than ever. “Just help me get the cake mix ready, and if you do a good job, I’ll suck you off. How does that sound?” He smiled and winked at his brother while holding the feather duster between his hands.

Alvin’s eyelids fluttered, his tongue falling out of his open mouth. “Well, ok…” he sighed. He followed Theodore into the kitchen, the feather duster conducting his steps like a pied piper.

***

The sounds of Alvin and Theodore’s banter travelled all the way to the basement, where Simon was hard at work. His sweater sleeves rolled up, his glasses tethered to the back of his head via a cloth strap, Simon kept looking back and forth between his workbench and the schematics taped to the wall. On his workbench, hand crafted by Dave years ago, were an assortment of various tools such as a hammer, socket wrench, copper wires, small wheels, and other such things.

The commotion upstairs didn’t bother Simon much. When he was in his flow state, working on his projects, it took a lot to distract him. In the basement, one could hear Simon rustling tools back and forth, tinkering with various nuts and bolts. Nuts… Simon chuckled at the double entendre. He was still a child after all, though he was now 13 and full of budding hormones. Hormones that this pulley system would help stimulate…

The hemp rope Alvin had gotten him a few weeks ago lay in a corner on the worktable. Simon pulled the rope up and wound it around one of the wheels. His fingers came across a frayed part and he stopped suddenly. He took a closer look at the frayed bit of rope and realized it was the part where Alvin bit into it. Simon’s glasses flashed. His cheeks flushed as he remembered the helpless look on Alvin’s face. Needy little faggot, thought Simon, and he smiled. He loved seeing Alvin like that, tied to a cuck chair, reduced to a pathetic fucktoy. Simon’s cock twitched at the thought. It is my birthday… After adjusting his underwear, now moistened thanks to his leaking hard member, he picked up another tool and went back to his work.

Simon’s Birthday Cake Recipe

Ingredients:

4 Eggs

¾ cup (165g) caster (superfine) sugar

1 cup (150g) wheaten cornflour

¼ cup (30g) custard powder

1 teaspoon cream of tartar

½ teaspoon bicarbonate of soda

900 ml thickened (heavy cream)

1 tbsp icing (confectioners') sugar

½ cup (160g) strawberry jam

250 grams strawberries, sliced thinly, plus extra 125 grams, halved to serve

1 teaspoon chipmunk brother semen

Alvin’s tongue up Theodore’s ass: 2 swirls every 2 seconds

***

“Mmmmhh~” moaned Theodore.

He struggled to focus on the cake recipe while Alvin dug his tongue up his ass. The seat of Theo’s big panties were already torn open, giving access to his enormous, delectable bottom. His anus puffed and conformed to his brother’s tongue invasions. 

“A-Alvin… just… would you wait a second~?” Theo gasped and pulled himself together enough to put the eggs and the caster sugar into the mixer, then press the “on” button. He smiled as he felt Alvin’s face press deeper into his ass cheeks. After sifting cornflour, custard powder, cream of tarter, and bicarb twice onto his baking paper, he said, “Alvin, can you just lay on the floor for me for a second?”

Alvin paused. He pulled his face out of Theo’s ass and looked up. “What? Why?”

“You’ll see.”

Alvin shrugged and simply did as Theo asked. He lay on the floor staring at the kitchen light overhead for less than a second before darkness smothered him, followed quickly by the more potent smell of Theo’s rectal cavity. For a moment, he couldn’t breathe. Then, every pleasurable smell and feeling smacked him in the face all at once.

“Mmmmppphh~!!” Alvin flailed his arms this way and that, then shivered as he laid his hands on Theo’s ass, which sat comfortably right on his face. His nose poked up inside the anus, followed quickly by his tongue. Theo lifted his butt up a little and then smacked it right back down on Alvin’s face, making the older brother shake with violent pleasure. He did this a couple more times until he saw a dark spot blot the crotch of Alvin’s sweater. Smiling, Theo got up and lifted his brother’s red sweater, catching two or three spurts of cum in a vial he held in his right hand. Alvin, sighing with satisfaction, lay twitching on the ground while Theo went back to cooking.

***

Dave rolled his cart down the aisle of the Party City and frowned. He couldn’t remember the nightmare that woke him up that morning, but it still lingered in his mind for some reason. He couldn’t fathom why something he couldn’t even remember still upset him so much. Rubbing his head, he took out the list Theodore gave him and read it again.

Let’s see… I’ve got the balloons… the paper plates and napkins will be cheaper at Walmart… He pushed his cart out of the aisle. I think the candles are this way - “Oof!”

“Oh, my!” said Ms. Miller. “Now you just watch where you’re going mister… Oh, Dave, it’s you!”

“Hi, Ms. Miller,” said Dave. He scratched his head. “Sorry, I didn’t see you there. This cart seems to have a mind of its own sometimes.”

Ms. Miller smiled “Oh, that’s alright. Now what are you doing here, David?”

“Gathering supplies for Simon’s birthday party,” said Dave. “You and the girls are gonna make it, right?”

“Oh, of course! The girls wouldn’t miss Simon’s tenth birthday for the world! Big day in a boy’s life!”

“He’s turning thirteen, Ms. Miller.”

“Well, obviously, that’s what I said, David. You get that corn outta yore ears!”

Dave sighed. “Anyway, what brings you here?”

“Oh, just grabbing a few things for the girls. They’re having a big get-together with their girlfriends this afternoon and, well, you know Brittany. She darn near wants me to buy out the whole store for the shebang.”

Dave blinked. “I thought you just said you all were coming to Simon’s birthday party.”

“Well, we are, David! Don’t think we would be so rude as to miss Simon’s birthday.”

“And… the girls are also having their own party… at the same time?”

“Well, um…” Ms. Miller thought for a moment, then waved her hand. “I’m sure they’ve worked it all out.” She walked her cart up to Dave and patted his face. “Don’t you worry, now, David. You always worry so much. You know that makes you age faster, gives you wrinkles. Just look at me. Why do you think I don’t have any wrinkles? I don’t worry about a thing!” She threw her head back and laughed as she walked away.

Dave blinked and shook his head. As he walked into the next aisle, he noted that for once Ms. Miller was actually right. As old as she was, and she was quite old, Dave couldn’t remember seeing a single wrinkle on her face.

***

Alvin still lay on the floor by the time Simon’s cake was done. After placing the cake in a big pink box, Theodore wrapped a bright red ribbon around it and tied it in a neat bow. Smiling, he then picked up the cake and placed it in the fridge.

“Whew,” said Theo. He wiped his brow. “Time to make lunch!” His ear pricked then as he heard Alvin moan from the floor. Sighing, he said, “Alvin, are you gonna get up and help me or not?”

“Blehhh,” said Alvin.

“Hmph,” said Theo. “Well, if you’re not going to help, then get out of the kitchen. You’re in my way.” He took out his feather duster and waved it in Alvin’s face. “Go watch TV or something.”

Alvin pushed the feather duster out of the way. “You’ve been hard at work all morning, Theo. Don’t you think you could use a break?”

“Well…” Theo thought for a moment, and then sat down. It was then that he realized how tired he was. “Ooh, you’re right. I could use a quick breather.”

Alvin smiled as he got up and lifted his sweater. His undies were still moist, his hard cock practically bursting from the elastic. “What a coincidence” said Alvin. He hooked a thumb into the waistband of his undies and pulled down, releasing his leaky cock. “My dick could use a breather, too, hehe.”

Theo blushed. “You’re hard again already. Jeez…” Theo squeezed his thighs together and bunched up his skirt, trying to hide his own boner. “Well…”

“All you have to do is let me give you some breakfast,” said Alvin, winking and stroking his dick.

Theo sighed. “Ok, but let’s go to the couch. I’m not getting on my knees on this dirty floor.”

***

The tiny screen flipped on and illuminated Simon’s glasses. On the screen were two black pixelated dots. They morphed to horizontal lines twice. Underneath the screen, which was powered by receptors connected to the metal box in which it was housed, was a small rectangular opening. Beneath this assembly, which served as the head, was another metal box with arms attached to each side. At the bottom of the box were fixed tracked wheels with rotation capabilities. The robot, which was no more than 5 inches tall, blinked again. Simon smiled and folded his arms.

“Hello,” said Simon.

“Hello,” said the robot. It stared and blinked again. “What is my name?”

“Hmmm…” said Simon. “We’ll call you ‘Psyke,’ for now. Understand? You are ‘Psyke.’”

“I am ‘Psyke,’” said Psyke. “What is my purpose?”

“You are my new friend,” said Simon, smiling.

The robot blinked. “Friend…”

Simon’s glasses flashed. “With purpose comes many tasks that I will now outline…”

***

“Ohhh…” moaned Alvin. “D-Don’t stop, Theo, that feels sooo gooood!”

The brown leather couch creaked softly to the rhythm of the boys’ movements. As he gorged on Alvin’s twitchy cock, Theodore vaguely remembered helping Dave pick the couch out. The couch was a fine, dark brown leather that was just the right combination of firm and soft, just like Theodore himself. They bought it on a Saturday and Dave had just taken Theo out for ice cream. The smell and taste of the vanilla washed back over Theo as he licked up Alvin’s rod, wrapping his lips over it like he had the ice cream cone. He could feel the twitches of Alvin’s member get faster and faster as Theo played with his balls, poking his finger up right where he knew the prostate would be. The fabric of his fingerless gloves brushed against the couch as he dug another finger deep into Alvin’s ass crack, reaching and poking at the twitching hole.

“Gughhhh,” groaned Alvin. His eyes crossed in different directions.

The final poke sent Alvin over the edge. Theodore breathed in deep through his nose and held it as Alvin’s cum splashed down his throat. He swallowed and breathed again as cum shots hit his mouth. Theo was a quick study. He learned how to bottom faster than Alvin did because, unlike Alvin, he was patient. The same patience he applied to cooking and cleaning, he applied to taking dick. Everything was all about patience.

After swallowing the last shot of cum, Theo let the slackening cock pop out of his mouth and licked his lips. “All good?” He looked up at Alvin and smiled as he sat back on the couch.

Alvin sighed. “Yeah. You’re such a good brother~” He sat on the couch next to Theo, adjusting his cap. “Well, what do we do, now?”

Theo frowned. “What do we do? I have to get back to the kitchen and make lunch.” He hopped off the couch and started toward the kitchen, swaying his large hips back and forth like a girl. Alvin bit his lip as he watched the maid skirt shift to and fro over Theo’s ass. His cock was already hardening again. He palmed his crotch and leaned back on the couch. Then, he looked up.

A metal hook attached to a pulley on the ceiling gleamed over Alvin’s head. Before he could scream, black duct tape was suddenly plastered over his mouth. His sweater was pulled off and he was naked suddenly, save for his shoes and red ballcap. In an instant, ropes wrapped around Alvin’s body, tied together in a tight shibari configuration. Then, the hook swooped down and snagged an opening at Alvin’s back and pulled him up. He lay suspended in mid-air, his arms and legs tied inward. He squirmed to no avail.

“Feel free to help me if you’re not too tied up,” called Theodore from the kitchen.

“Hmmpphhhh!!” shouted Alvin. He looked down, his body suspended at the halfway point between the ceiling and the floor. He saw what appeared to be a tiny robot with a blue screen for an eye socket and tracked wheels for legs. It waved up at Alvin.

“My purpose has been fulfilled,” said the robot. “My friend will be pleased…” It started to wheel away, then stopped. “Calculating… One more task found.” It then rolled its way to another part of the living room Alvin could not see. After a couple of seconds, the robot reappeared. In one of its hands was a small black chastity cage that was about the size of the robot’s midsection. It positioned itself, then the body rose steadily for a few seconds, long metal rods extending from its wheels. It stopped right in front of Alvin’s crotch. After a minute of whirring and stingy muffled squeals, the chastity cage was tightly secure. It was a perfect fit. Alvin’s cock throbbed from under the cold metal fixture, begging for a release that would not come.

“All tasks are now complete,” said the robot. It whirred its way back down to the floor. “My friend will be very pleased.” It then wheeled away, disappearing when it turned a corner out of the living room.

“MMMMPPPPHHH!!!” screamed Alvin. He squirmed and wriggled, making him bounce in mid-air slightly. His cock throbbed more, the skin underneath the cage turning red. Tears leaked from his face and dripped to the floor. Breaths puffed from his nose as lay suspended and helpless, listening to the sounds of Theodore’s kitchen work.

Chapter Text

“Oh, they just had to pick today to close, didn’t they?” said Dave. He scratched his head and looked at the “Closed” sign on the novelty shop’s front door. “Simon would have just loved that antique lamp from the 1920s… oh, well.” He walked back down the sidewalk to his car in the nearby parking lot. Dread hit his stomach when his car came into view. A pink paper slip was fixed under the windshield wiper.

“A ticket? But everybody parks here!” Dave looked around and saw a handful of other cars with pink parking citations. “Dang, they normally don’t charge for parking. There must be a new cop on the force coming around.” He sighed. “Oh well.” As he turned to open his car door, he bumped into someone yet again.

“Ms. Miller? What’re you… Oh, hi there.” In Ms. Miller’s place was a smaller, much older-looking woman. By contrast, she had many wrinkles on her face as well as on her hands, the backs of which were lined with thin green veins. She wore a black shawl that draped over her head and sleeved arms. A black robe hung loosely over body and legs. She stood hunched over a jagged cane. She looked up at Dave and smiled a crooked smile. One eye was closed, the other open but glazed over with a thick white ooze.

Dave shivered. “Um, can I help you, ma’am?”

“Oh, don’t worry, I’m just passing by,” she crooned. “Not every day I see a handsome young man like yourself.”

“Well, thank you. I’m very flattered,” said Dave. “Uh, it was nice talking to you but I do have to be go-”

“Can you spare some change?” she asked suddenly, raising her eyebrows. “I’ll read your fortune in return. I’m quite good at telling the future.”

Dave tugged at his collar. He looked at the old woman’s craggly hands. “Um… I don’t know…”

“It won’t take but a moment, deary,” she said. Her one white eye gleamed in the sun.

“Well… alright,” said Dave. She clearly needs help, he thought. And I know what it’s like to struggle. These are tough times… He reached into his pocket and pulled out two dimes and a penny. “There you are.”

“Wonderful,” said the woman. She smiled wider and put the change in her robe. Then, balancing on her cane, she took Dave’s hand and rubbed her thumb over his palm. “Hmmm… you are a father… of three adopted boys.”

Dave widened his eyes “Y-yes! How did you know that!?”

“Shhh.” The woman kept rubbing his hand with her thumb. Her eye widened suddenly. Her mouth trembled open. “Young man… did you have a nightmare this morning?”

Dave swallowed. “Yes. But…”

“IT IS AN OMEN!” she screamed, making Dave jump. “Young man! Your future… is one laden with lecherous gluttony and lust!” She turned to him and grabbed his shirt. “Young man! You are doomed! Doomed to a life of unrelenting sin!!! YOU MUST REPENT!!!”

“G-get off me!” shouted Dave. He wrenched her hand from his shirt and ran to his car door.

“YOU MUST REPENT!!!” The lady screamed again. She stumbled forward in front of his car.

Dave jumped into the driver’s seat and fumbled his key into the ignition. Seconds later, he was backed out of his parking spot and driving down the street. He still heard the lady scream “REPENT!” faintly through his car window as he turned past a stop sign. A sharp chill crawled down his spine. He calmed down the farther away he drove.

“Jesus,” he breathed. “What a crazy woman. I hope she gets some help soon.”

Her words rang through his ears, making him shiver with each ring. He found himself fighting to remember the nightmare he had that morning. Shaking his head, he decided to skip his next stop and head straight home. He was about 30 minutes away from home, and he needed to be there. He needed his boys.

***

“Mmmmh, mmmmh, hmm hmm hmm hmm.” hummed Theodore. He bobbed his head back and forth to the tune of “Bad Romance” by Lady Gaga, which happened to be playing on the radio, as he finished up the chicken sandwiches. He made four, the last one for Dave, whom he gauged would be home soon after glancing at the clock. Once the last one was done, he adjusted his cat ears and put the plate on the dinner table. Wincing, he also adjusted his torn panties and walked to the living room, his maid skirt swishing back and forth.

“Alvin! Simon!” he called. “I’ve finished making lu- Oh!”

Theo’s eyes widened as he squealed. From the doorway between the living room and the kitchen he saw Alvin suspended in mid-air, naked, his limbs tied up tightly against his own body. Black duct tape sealed his buck toothed mouth shut. Clear liquid dripped from the tiny holes of his cock cage. Somehow, his bright red hat still clung to the top of his head. Alvin turned, saw Theo, and started wriggling again, puffing out muffled squeals. His nostrils flared with the strain of his nose breaths.

“Oh my gosh!” squeaked Theo. He stood frozen for a moment, his heart racing. Something about seeing Alvin like this made him pause. Blood rushed to his cheeks. To his crotch as well.

“Hey there, bros,” said Simon. 

Theo screamed and turned around. He saw Simon by the stairs. Light flashed in Simon’s glasses, the remainder of his body concealed in shadow. Simon stepped forward into the living room wearing a slight smile. He looked back and forth between Theodore and Alvin. He licked his lips as he looked back at Theo. “That’s a cute outfit, Theo,” he said.

“Um, t-thank you, Simon,” said Theo. “D-don’t you think we should get Alvin down, now?”

Simon looked back up. “No, I think he’s fine just like that,” he said.

Alvin stared at Simon with bulging eyes. More liquid leaked from his cock cage. A pool was forming on the floor directly underneath.

Suddenly, right beside Simon’s foot, a little robot appeared. “Did I do good, friend?” it said.

Simon chuckled and looked down. “Yes, Psyke,” he said. “You did very well.”

The dots in the robot’s little screen that signified eyes changed to two upside down curves. It smiled at Simon.

Theo looked back and forth between the robot and Simon with a lump in his throat. He gripped the middle of his maid smock and swallowed. His face was a bright shade of red. “U-um, I m-m-made lunch, Simon. I-it’s s-spicy chicken sandwiches. Y-your favorite.”

Simon smirked at Theo. “Oh, thank you, brother. I love chicken sandwiches.” He walked up and drew close to Theo, then bent down so that his face was less than an inch away from his brother’s. “But right now… I think I want to taste you first.” He licked his lips again and brought a finger up to Theo’s face, dragging the padding of his forefinger from his nose down to his lips.

Theodore’s composure fell apart like putty. His mouth fell open and absorbed Simon’s finger. He was careful not to let his buck teeth touch the backs of the fingers he sucked on. He gripped his own clothes tighter as Simon pulled him in closer. Breathing softly into the side of Theo’s neck, Simon slid his hand into the small of the smaller boy’s back, inching his fingers down the fat butt crack.

“Mmmmh~, would you look at that,” breathed Simon. “A nice little entry hole is already there for me. Thanks, Alvin.”

“Mmmpphh~” moaned Alvin. He twitched and convulsed periodically, unable to tear his eyes away from his brothers’ embrace. He watched them make out in front of him, a tear leaking from one eye. His cock throbbed from under the cage, semen leaking out of it faster now.

“Ohhh, Simon…” moaned Theo. He squealed a little as he felt Simon’s finger dig into his butt hole. It slipped in easily, as though it were already wet. Theo’s eyes fluttered as Simon kissed and fingered him at the same time. The finger plunged deeper inside, all the way to the knuckle, making Theo shiver.

“Mmmhh~” moaned Simon. He kissed Theo’s cheek, then his neck, as he worked a second finger into Theo’s backdoor. The hole practically opened itself for him, the sphincter twitching its expansions around Simon’s fingers. Simon worked his snout down Theo’s shoulder, sliding the silky nylon strap out of the way with ease. Slowly, he turned Theo around and kissed the back of his neck, then slipped his way down so that his face was in front of the younger boy’s ass. Dislodging his wet fingers, he dug his nose into the furry flesh crevice.

“Ughnn,” Theo gasped. He pressed his hands against the wall for balance.

Simon pushed his nose in deeper, rubbing it in a bit before diving his tongue down the hole. His tongue unfurled and sunk into the anus nice and deep. He breathed in the anal juices, inhaling his brother’s hole like a starving boy. Almost subconsciously, his hand drifted to his cock, which stood at attention, poking through his undies. Then, he spat on the hole and stood up, lifting his sweater. He leaned in close, hugging Theo’s back, and slowly pulled his underwear down. His leaky cock, standing at 7 inches, sat comfortably between Theo’s ass cheeks, tucked deep into the furry crevice.

“I see, you’re already loose,” Simon whispered. He breathed into Theo’s ear, making him shiver with pleasure. It only took one back up for Simon to position his cockhead on the twitching hole. Softly, he bit Theo’s ear as he pushed inside nice and slow, tapping his waist to the bulbous buttocks.

“Ooohhh~” whimpered Theodore. He bit his lip as he let Simon press his face into the wall. His fingers curled into fists. He felt the familiar filling sensation heat up his stomach. The white hot sensation of the pulsing rod digging deep into his belly, scraping his prostate as it plunged on through. Goosebumps electrified all the little hairs on his furry little body.

Simon dove his lips into the crook of Theo’s neck and kissed him as he humped inside him again. He wrapped his arms around Theo like a passionate lover and thrust his cock inside again. His tendril-like fingers found their way up to Theo’s mouth, giving him something to suckle on. Licking Theo’s cheek, Simon thrust inside again harder, and then began pumping at a steady pace. The claps of furry waist on furry bottom echoed across the living room.

Then, Simon smiled, a flash of light illuminating his glasses. “Alright, are you ready, brother?” he whispered. “I’m gonna fuck you harder now.”

“Wha..? Mmmnnghh~” Theodore gasped into the cloth that was suddenly wrapped into his mouth, gagging him. There was a mighty tearing, ripping sound, and Simon grabbed Theo’s hands and thrust them behind the small of his back. Theo’s face was already being pressed into the floor by the time he realized it. His hands were tied together with his own torn underwear.  He lay on the floor, his ass sticking up in the air, still filled with Simon’s cock, which had never dislodged itself all while Simon tied up Theo and tossed him to the floor like a rag doll. Now Simon lay over Theo and grabbed hair on his head in a tight fist. He bent over and licked Theo’s cheek again. Then, he gripped Theo’s ass with both hands, digging his fingers into the love handles, and pounded his hips into the clapping ass cheeks fast and hard. The slaps were much louder and faster now.

“Mmmmnnnghhhh - Nngg - Ngg - Ngghh~!!!” squealed Theodore, his eyes popping from their sockets.

Alvin helplessly watched his brothers fuck, tears leaking from his eyes. He wriggled and squirmed on instinct, making his body sway in the air like a pendulum. He knew it would not help, but he wanted to move anyway. The ropes bit deep into his arms and legs. The tight knots, wound with perfect precision, clung to his naked chest, stealing a few strands of hair whenever he squirmed. The pool of precum underneath him was larger now, having leaked from his restricted cock like a faucet. He was so near a climax that it was painful, unbearably painful. This hurts… so much, he thought. On… so many levels, but… do I like it? The thought made his cock twitch from under the cage yet again.

Then his eyes drifted up. Alvin saw a tiny red dot in a dark corner of the living room. He squinted his eyes and saw the red dot on a screen fixed to a little robot body. The screen was aimed directly at Simon and Theodore. It periodically panned upward to look at Alvin. Psyke’s black digital eyes winked at him.

“Fuck yes!” growled Simon through gritted teeth. “God your ass is amazing, Theo! I just love fucking you like a little bitch!” His voice cracked a little when he said “bitch.”

Theodore squealed through his gag with ecstasy. His face rubbed against the floor with every thrust, his cat ears cocked to one side, slightly off his head. The torn undies dug into his wrists. Slowly, he felt his body turn to the side. Simon lifted Theo’s leg up and turned him over, then kept fucking him sideways. Juices started oozing from Theo’s ass and moistened his crumpled maid skirt.

“Mmmnnggg…” gasped Theodore. 

While Simon pressed his length into his younger brother again and again, Alvin forced to watch, his face twisted with mixed emotions all equally intense, the Chipmunks failed to hear a car park in the driveway. The rustle of keys, the dying of Dave’s car engine, and Dave walking up to the front door. All these sounds went completely unnoticed until Dave opened the door.

Chapter Text

Dave pulled his car into the driveway and slung the transmission into ‘park’. He shivered, the crazy old lady’s voice still ringing in his mind. He shook it away as he got out of the car and began taking bags out of the backseat. 

You don’t have to take them all, Dave.

Despite Simon’s voice telling him otherwise, Dave did indeed take as many bags as he could carry out of the backseat and shouldered the car door closed. He wrestled his keys back out of his pocket as he approached the front door. Grunting, a bag strap in his teeth, slid the door key into the slot after a few seconds of stabbing it. 

During those seconds, some muffled sounds from behind the door reached his ears. Part of his mind registered these as muffled cries for help. His heart rate spiked, and after turning the key a little too fast, he pushed the door open.

What Dave saw when he walked into the living room made him do two things. 1) Stare at Simon and Theodore on the floor; at Simon laying over Theo with his cock lodged firmly up his ass; at Alvin tied up in a series of complex knots and suspended in mid-air. 2) Drop all of the bags he was carrying. Party favors spilled from the bags and glittered on the floor. The boys froze and looked at Dave in unison as soon as he opened the door.

Dave had come home to find his chipmunk sons doing an endless list of things that shocked him, most of them done by Alvin, and thought he had seen everything. Nothing could have prepared him for this moment, however… or so he thought. Then, the old lady’s premonition came to his mind once again.

You are doomed to a life of unrelenting sin!!!

“Dave?” said Simon. “Um… I can explain…” A small metal object that looked like a toy turned its screen toward Dave, aiming its little red light in his face.

Slowly, Dave shuffled his way farther into the living room, closing and locking the door behind him. “B-boys…” he said. He felt blood rush to his cheeks. “T-these are some, uh… interesting bonding activities…” Dave’s crotch suddenly stirred. The more he stared at his boys in this way, the higher his heartbeat rose, pumping more blood to his face and crotch area.

Simon noticed the tent forming at Dave’s groin immediately. His eyes trained on the blossoming boner like a homing beacon. His face twisted to a slight smile.

“Why, of course, Dave,” said Simon. “This was, uh, a special surprise that Alvin and Theodore prepared for my birthday.”

Dave swallowed. A mixture of disgust and desire boiled his blood, threatening to make him speechless. He simply didn’t know what to say next. He thought, I… can’t believe I’m considering… but my boys… they look so… 

“Oh, well, that’s very thoughtful of them.” It suddenly felt hotter in the living room, and Dave took off his sweater.

“You know, you can join us, Dave,” said Simon, flipping his eyes back and forth between Dave’s crotch and his eyes. He looked at Dave with half-lidded eyes. His cock was still throbbing hard, still secured up Theo’s ass. He winked at Dave and thrust his hips forward, making Theo whimper with delight.

That thrust was the final straw. Dave even surprised himself by smirking, his cheeks redder than ever. “Well… I-I guess the decorating can wait. Since you boys are so eager to have fun before the party.”

“It’s family time, Dave,” said Simon. “That’s what I really want on my birthday.”

“I see,” said Dave. “Well, if you insist…” He stepped forward and pulled his t-shirt off, revealing a muscular physique that bristled with life. The lights in the living room gleamed off Dave’s hairless pecs, shining his taut deltoids and biceps. For a moment he seemed to move in slow motion, and all three boys looked at him with gleaming eyes. 

“W-wow, Dave,” said Simon. “I… I didn’t realize you were so ripped.”

“What?” said Dave. He looked down at himself. “Oh, well, yeah. I’ve gotta be strong to take care of you crazy kids.” He knelt down in front of Simon and Theodore, and he placed a hand on Simon’s cheek. “I… just love you boys so much. I can’t bear the thought of anything happening to you.” Dave leaned in closer to Simon’s face

Simon’s cheeks were bright red. “You’re… such a good da-” said Simon. He breathed into Dave’s lips. Simon’s cock was harder than ever, and he thrust into Theo again as Dave kissed him. It was a slow, passionate kiss. Dave’s tongue waltzed into Simon’s mouth while he palmed the boy’s cheek. His hand drifted down to his belt buckle. Before long, his thick 9-inch rod fell out of his underwear, already dripping with precum. A droplet of hot man juice fell on Theo’s face. “Mmmhh~” Theo whimpered. 

“I think…” whispered Simon. “I think Theodore wants a taste of you, Dave.”

 “I see,” said Dave. He hooked a thumb into the cloth gagging Theo’s mouth and pulled it out while stroking his cock. “Well, I’m more than happy to give my growing boys what they need.”

Dave eased his cock into Theodore’s open mouth letting the fur-lined lips absorb his shaft. Theo’s eyes fluttered closed, and he sighed with satisfaction. The cock slipped slowly into his mouth and down his throat, filling its new sheath. Dave, careful not to push inside too far, eased it in and back out slowly. He felt strained breath through Theo’s nostrils graze the side of his shaft. As he slipped his rod through his younger son’s lips, he leaned in and kissed his older son again, letting his tongue mingle with Simon’s. He remembered suddenly that he used to kiss his boys a lot more when they were smaller, closer to toddlers. He wondered why he stopped as they grew older.

Just above the threesome, Alvin’s whole body shook, sweat gleaming across his fur. He pressed his arms and legs against the ropes that bound them to no avail. The shibari knots were tied with precision and perfection. The cock cage bit deep into his swollen third leg, reddened flesh poking through its holes, which were moistened with cum. Alvin had lost count of how many times he was close to ejaculating, and was amazed he hadn’t gone insane from watching his family fuck right in front of him for nearly an hour. It was a torture he could hardly stand, but one that pushed him to new heights of pleasure he hadn’t previously thought possible. The sight of Theo’s mouth absorbing his daddy’s thick and veiny cock, a cock he wanted in his mouth badly, drove him wild. Jealousy, desire, hate, love, lust. All these feelings festered inside Alvin, made him squirm uncontrollably. The brim of his hat swung up and down like a bright red diving board.

That redness sparked a glint in Dave’s eye. He looked up at Alvin squirming against his restraints. Something inside Dave ignited once again. Dave’s cock hardened and he thrust into Theodore’s mouth just a little bit harder, making the younger chipmunk gag and choke. Biting his lower lip at the sound, Simon pressed his cock deeper into Theo’s ass, pressing the chubby little bottom even further into Dave’s crotch. Theo could hardly breath, his eyes rolled up with ecstasy.

In the corner, its screen pointed at the perverted family, their bodies mingled together, sat Psyke. The red dot in the corner of its screen glinted, the data from the recording being saved in real time to the terabyte disk drive installed in its little body. Simon was truly a genius, having invented a way to install the tiniest chip possible with the maximum amount of data storage in a small robot. So focused was it on recording, however, that it could not control via bluetooth the pulley system Simon had installed. A glitch occurred somewhere in the pipeline. Slowly, Alvin’s body descended to the ground.

As if predicting Alvin’s descent, Dave stopped kissing Simon and held his hand out. Alvin’s belly fell gracefully into the palm of Dave’s hand, and Dave lifted him off the hook. His cock still in Theodore’s mouth, Dave slowly pulled the tape off Alvin’s face. He looked into the boy’s eyes and kissed him, sliding his hand down the arc of Alvin’s back. The butthole, already opening and closing by itself, absorbed Dave’s probing fingers. Dave used the ass as leverage to hold Alvin up while he kissed him. A sixth sense rose Dave’s other hand, and the fingers drifted into Simon’s pining mouth.

The living room was now a symphony of moans and wet smacks. Theodore slid back and forth on the floor between Dave and Simon, his hands still tied behind his back, the folds of his maid uniform crumpling against his movements. Simon sighed passionately, absorbing Dave’s probing fingers, letting them massage his eager tongue. Alvin winced as his legs spread apart on the floor, two of Dave’s fingers stuffed firmly up his backdoor, making him cross-eyed. Juices leaked from his cock cage. A bittersweet angst flowed through Alvin as he mingled his tongue with Dave’s.

Dave kissed his son harder, moaning into his small chipmunk lips, loving the light layer of fur that brushed against his skin. After thrusting once more into Theodore, he pulled his cock out of the boy’s mouth. Alvin looked down at it, his eyes sparkling. Light gleamed from the moist meat slab that stood from Dave’s crotch. It twitched up, the head glistening with saliva, pointing up at Alvin, who licked his lips. Dave kissed Alvin again before repositioning his body so that the boy was in front of Simon. The brothers looked at each other in a haze of pleasure.

Alvin gazed at Simon through the shining lenses. He felt the heat of Simon’s breath on his cheeks as their faces drew closer together. A glint of a smile on Simon’s face appeared right as Alvin felt his butthole dilate. The needy brat’s eyes bulged from their sockets as he felt his daddy enter him slowly. 

Dave looked down and watched his cock slip inside his son’s ass. Time slowed, and he briefly remembered the horrible encounter he had with the old lady outside the antique shop. Her crazy shouts rang once through his mind. He thought one thing:

I guess this is what she meant… fuck it.

With that, he stuffed the rest of his cock into Alvin, who squealed with pleasure. “Oh… oh, Dave,” he whimpered. “So big.”

“Sorry, Alvin,” Dave said. He reached a hand up and caressed his son’s cheek. “Too big for you?”

“N-no!” panted Alvin. “Feels… so good. P-please fuck me, daddy~”

“Hehe, I see,” said Dave. “Well, alright then.”

As Dave continued thrusting in, Alvin’s face was pushed into Simon’s, and they kissed. Dave’s thick manly fingers dug into Alvin’s small yet pudgy thighs as he pressed his cock into the boy’s stomach so hard it poked through his belly. Alvin’s eyes bulged, his tongue spilling into Simon’s mouth. Theodore was on his back now, Simon fucking him missionary. Alvin’s balls, tightened slightly by the cock cage pulling on the skin surrounding his cock, dangled just above Theodore’s mouth. Puffing hot breaths onto the tight ballsack, Theo lifted his chin and lanced his tongue out.

Alvin could feel the slight wetness to his under carriage as Theo dragged his tongue across the undulating sack. A hurricane of feelings blew through Alvin as he felt his ballsack licked, his mouth inhaling Simon’s breath and tongue, his asshole absorbing his daddy’s thick pulsing member. Every thrust of Dave’s cock dilated Alvin’s hole until it was about twice it’s normal circumferance. Every inch of Alvin’s body felt every inch of Dave’s rod slipping inside him, the man’s waist clapping against his thick booty cheeks. Wave after wave of ecstasy soared through his insides mounting up to a roaring crescendo.

“Unnh… Unnhh… AHHH!” 

Alvin’s convulsions were intense. Liquid dripped from the bottom of the cage to his ballsack and fell into Theodore’s open mouth. This, combined with one final thrust from Simon, caused an intense orgasm to ripple through Theo’s undulating body. Cum spat from his twitching cock and splattered onto Alvin’s belly. Simon, after thrusting in a couple more times, moaned hard as he filled Theo’s guts with his hot semen.

Dave was the last to cum. He gripped Alvin’s thighs and slapped his waist to the boy’s ass as he felt his climax mount up. Reaching the zenith of his pleasure ride, Dave lowered his head and kissed Alivin’s neck as he dumped his load into him. The white heat from Dave’s load made Alvin cross-eyed.

The Seville family orgasm preceded another round of hot passionate sex. The family orgy continued for another hour. On the other side of the living room, perched atop the flatscreen TV, was Psyke, Simon’s little helper bot. The red dot gleamed softly from the top right corner of its screen.

EPILOGUE

3 hours later…

Brittany Miller arrived at the Seville doorstep with her head buried in her phone. She had just barely gotten her hair to look right after about 2 hours in front of the mirror and about 3 or 4 posts on TikTok about how to apply blush on fur. These posts were about 5 million short of her usual 40-50 million likes. “Damn A.I. vids…” she growled as she approached the front door.

“Brittany, can you - ugh - help me carry this?” Jeanette struggled from the weight of the bags she carried from the driveway.

“And ruin these nails I spent thirty minutes finishing?” said Brittany. “Jeanette, please… I can help you carry things after the party, ok?”

Jeanette blinked. “But we won’t have… oh, nevermind.”

Eleanor got out of the backseat and slammed the door closed. “Oh my god, Brittany!” she said. She took a couple of handbags from Jeanette. “You could at least carry two or three bags.”

“Now, now, no fighting, girls,” said Ms. Miller. She exited the driver’s seat of her pink Honda Accord, which was parked askew in the driveway, skid marks from the front lawn trailing from the back tires. Ms. Miller wore an overly extravagant dress, one fit for a gala. The Chipettes wore their usual clothes. “I don’t want ya’ll to spoil the surprise for Simon.”

Brittany blinked. “Surprise? I thought they were already partying and we were just visiting.”

“Hehe, that’s what I wanted you to think,” said Ms. Miller. “But, surprise! We’re throwing Simon a surprise party!”

Brittany blinked again.

“Haha! Good one, Ms. Miller!” shouted Eleanor. She nudged Brittany. “You could at least try to play along,” she whispered as Ms. Miller went up to the door.

“Jesus, sis!” Brittany rubbed her arm. “Be more careful! You could have ruined my makeup!”

Eleanor sighed. Jeanette shuffled up behind her sisters. 

Ms. Miller rang the doorbell. Only seconds later, the front door opened.

“Oh!” said Dave. “So glad you could make it! Come on in!” He opened the door some more and let the girls in. “So that thing ended just in time, huh?”

“Huh?” said Brittany. “What do you mean?”

Dave rubbed his head. “Ms. Miller said you would be having a get together with your friends at the same time as the party.”

Brittany rolled her eyes. “I told her that I would be having a get together on stream. Like on my Discord channel, Ms. Miller.”

“Now you keep talking about a channel called Discord,” said Ms. Miller. “But I keep flipping through our TV and I can’t find it. You’re gonna have to talk to our cable company because I done fussed them out too many times.”

Dave chuckled. “Well, anyway, happy to have you all here. Come on in and have some cake.”

Ms. Miller and the Chipettes walked into a living room filled with decorations and party favors. They mingled with the Chipmunks and had some chocolate croissants Thoeodore made. After a few minutes, the birthday boy, Simon, walked up from the basement downstairs and was met with a round of applause the moment he stepped into the living room. Smiling, Simon stepped into his family’s loving arms.

“Make a wish, Simon,” said Dave.

Simon sat in front of the cake and closed his eyes. He thought for a moment, then blew out all of the candles. Everyone clapped their hands and smiled at him.

In the corner of the room, unnoticed by all, was a tiny robot named Psyke, its little red dot glowing.

“Happy Birthday, friend…” it whispered.

End.
