A note slipped in from under the door, followed by a gentle knocking that caught the boys' attention, causing the three chipmunks to perk up.  

"Mom?" Alvin called out. There was no response.

Getting up from his bed, Alvin went over to the door and picked up the piece of paper. On it was a couple of lines, written in their mother's simple, yet large handwriting:

"Your surprise will be ready in 10 minutes. Come to the dining room.

Love, Mom."

"Awww Mom… playing hard to get, even after all this… I think I like it~." Alvin hummed himself, letting out a soft moan as he sat down on the floor, his hands went to his crotch, relieving himself with a few slow strokes. Next to him, Theo chuckled as he crawled over to watch his aroused brother while Simon rolled his eyes.

It was just after dinnertime and the dishes were all washed, when Vinny had asked her sons to go to one of their rooms and stay there until further notice. Despite any advances made earlier that day by the boys, Vinny insisted on waiting until after dinner before they got into it.

"I'm sorry, my dears, but it's a surprise. Just give me a few minutes to prepare, okay? I'll let you know when I'm ready." That was all Vinny had said before she closed Alvin's door on them.

With each passing minute, the tension in the room had slowly built up, leaving Alvin to quickly strip all the way down, followed soon by Theodore. Even Simon, who at first remained stubbornly clothed, followed in suit.

"We've already seen everything we used to keep hidden, what's the point in having our clothes on?" argued Alvin.

And so the boys waited in Alvin's room (with Alvin now pacing up and down), completely naked while their cocks twitched and throbbed about in the still air, slowly hardening and becoming erect as they gazed at each other. Even Simon was slowly getting stiff from the passing glances he got of his brothers.

Clearly, their levels of excitement were bubbling to a bursting point.

"Alright, guys, here's the deal." Alvin spoke up to break the silence and gesturing to his brothers. Following his lead, the three of them sat in a circle, huddled together on Alvin's bed. "We all wanna have a good time with mom tonight, yeah? Well, we can't just ambush her with our shafts out. I mean, we can, but we'd never be able to stuff all three into one hole.  So we're gonna need some way to decide."

Simon looked at Alvin, surprised. "Oh? Alvin, are you suggesting that we do something orderly that doesn't end in trouble?" He teased, causing Alvin to shove him softly. 

"Yeah, yeah, I get it Si. I don't plan ahead a lot, but there's no way I'm just gonna force myself onto mom.  She deserves a whole lot better than that. So… Any suggestions?" He asks, tail flicking side to side. 

"Hmm… Well, I'm not all too certain, but I suppose we could try to figure out a way to just pick a spot and stay there throughout the session." Simon replied, wrinkling his nose a little.

Alvin rolled his eyes. "Yeah, Si. I'm sure mom would be on board with that." He scoffs. 

"And you can think up something better, Alvin? Give me a break, this is the last day we'll see mom in a while." Simon snaps. "I just want this to be enjoyable for her too."

"Well…" Theodore interrupted, shuffling a little on the bed. "If we can't just pick then… We could play Rock-Paper-Scissors?" He suggests, his tail lowered sheepishly. "Like… Whoever wins gets first pick, and we just go from there?"

"Theodore, please, that has got to be the…" Simon stopped himself. It was at least an idea… and for once he couldn't come up with anything better himself. "Well… I suppose we could give it a try. It's diplomatic, at least, to some odd degree."

Alvin nods his head, tail thumping lightly on the bed. "Great thinking, Theo!" He says, a little grin showing on his face as he pats Theodore's back, down close to his rear. As Theodore looked away with a blush, Alvin stood up and cleared his throat. "Alright boys! Last munk standing gets to have mom's sweet, sweet honeypot~" he says, putting his paws on his hips. "Second place can go for her butt, and third gets mom's mouth. Any questions?"

"Yes, just one." Simon spoke up. "Could you please watch where you're pointing that thing? I'd rather not have your penis poking at my nose." Simon huffed, reaching out to push against Alvin's crotch, his stiff length having poked against Simon's cheek when he stood.

"It's called a dick. The ol' pork sword, if you will~" he boasted, humping at the air much to Simon's obvious annoyance.  "Heheh. Fine, Si. I'll point it at Theo instead." Alvin says with a shrug, pressing his cock against Simon's face once more before sitting himself down. "May the best munk win~" he says, ignoring Simon's stream of threats.

__________________________________________________

"Ready or not, Mom, here we come!"

Alvin's voice rang through the empty hallways as he and his brothers walked out from his room. At first, it seemed like no one else was around.

"Ya know, we can still have a redo." Alvin said, glancing sheepishly at Simon. "Ya know, how about best two out of three?  Just to be sure we didn't have any-"

"Not a chance, Alvin. You lost first fair and square." Simon responded, giving Alvin a little push forward.  "Besides, are you really saying that mom's mouth isn't good enough for you?"

"That's not what I mean, Simon! It's just-" Alvin's paused as they entered the living room. He turned his head up and started sniffing; a warm, delectable aroma had filled the air. Sure enough, it was coming from the entrance of the dining room. Alvin, sniffing and breaking into a wide grin, peeked back at his brothers. "Hey, doesn't that smell like-"

"Mama's acorn soup!" Theo squealed with joy, his eyes wider than saucepans.

Then slowly, a faint humming could be heard leading into the dining room. The boys perked their ears up, excited. It was a sweet, melodious voice that was singing – and even brimming with a hint of lust.

"Oh boyysss… Come and get your surprissseee… Mama's waiting." That cute little humming came up again. There was silence then, the three chipmunks trading glances. 

"Well... I'm not gonna wait any longer~" Theodore spoke.  The temptation to indulge was almost too much to bear. Eagerly, the boys rushed into the dining room with Theodore leading the charge.  

There, they found themselves in a softly lit hall, yet filled with a gentle glow, thanks to the many, many lighted candles placed all over the room.

The dining table had been set and laden with plates, including an assortment of berries as well as nuts and other gatherings from the forest. And right in the middle of the table, presented as a centerpiece, was a big tureen filled with acorn soup, which the boys saw Vinny setting it down. 

Like her sons, she was completely bare of clothes and displaying her naked body for them to gaze at in awe. She had let her hair down from its lazy ponytail, and even removed her glasses, showing off her clear purple eyes. At first, it seemed as if Vinny wasn't aware of her boys' presence, since she was still humming away as she set the table, its offerings suggesting a huge feast that was about to come.

"Oh, hi boys!" Vinny smiled, placing the last of the dishes. "You're just in time for the surprise!" Her legs parted a little as she stood in front of the table, revealing her pink, beckoning slit to them.

"Wow, that sure is a nice spread, Mom!" Alvin said, only to earn him a nudge in the ribs from Simon. "What? I was talking about the table, you perv. Geez!"

"Is this all for us?" Theo was the first to make his way to the table, licking his lips at the scrumptious feast awaiting them. Vinny nodded her head, making Theodore squeal once more, going for a bowl of berries.

"Ah ah ah, Theo." Alvin called, causing Theodore to freeze in his tracks, looking to Alvin with a pitiful whine. Chuckling, Alvin went over to his side, lightly patting his head. "I've got a great idea. We've already had our dinner, after all, so maybe we can put this food to some better use." he spoke. Alvin scooped up a bowl of berries, humming softly as he goes to squishing them up, his tail wagging as he does the same to two more bowls. When he was done, he gently cradled the three bowls, handing two off to his brothers.

"Alvin, what is this for?" Simon asks, looking down at his bowl. "Simple, my dear brother." Alvin answers, dipping his paw into his bowl, bringing it out to let the reddish juice drip into his fur, leaving behind spots and trickles. "Just a little something I learned from Theo, is all."

Hearing this, Theodore giggled softly, dipping his paw in his own bowl and smearing the juice into his tummy fur. "I know what you're doing, Alvin~" He says, tail wagging side to side. Simon was going to protest, but Vinny bumped him from the side, giving him an encouraging wink.

"Well… Here goes." Simon mumbled, dipping a paw into the bowl of bluish juice.
.........................
In no time, the boys had slathered the berry juice into their fur, even giving themselves a few distinct markings. Vinny joined in as well, taking some of the soup and rubbing it on herself, focusing on her chest and between her legs.

"Heh, you're looking good enough to eat, Mom." Alvin comments, moving himself close to Vinny, sniffing at her chest and licking his lips, putting a paw against her back. Vinny couldn't help giggling, lowering her head to lick some of the juice off of Alvin's neck. "Why, I could say the exact same about you three." She let her tongue linger on her son's neck fur, slowly lapping clean the traces of berry juice.

Alvin shivered from the contact, pushing himself closer to her. "Heh, c'mon Mom. Me and the guys had a little plan for tonight."

"Oh? Well, I suppose my plan could wait a little... Where are we going then?" Vinny asks. 

Alvin just hummed softly, taking hold of her paw and tugging her along. "Well, mom, you've been a little sneaky with us this whole week." He started, entering the living room. Once there, he sat himself down on the couch, quickly joined by Simon and Theodore. "So, since we made you feel real good, maybe tonight you can please the three of us~. I'm sure we'll all have plenty of fun." Alvin says, giving her a sly smile.

"Alvin, you naughty boy! Or should I say, what a big boy you've become... " Vinny couldn't help smiling, shaking her head slowly. "Alright, alright. Mama's ready for a little play time."

"Ohoho no, mom.  It's not gonna be a little~"  Alvin hummed.  "Boys, take your places!" At Alvin's word, Simon laid down on his back, splayed out on the couch.  Theodore turned himself around, facing Simon as he reached out to gently pat his brother's belly. "You go right here, Mama~" He cooed, his little tail swishing side to side as Vinny laid out on top of Simon, letting her nose bump against his.

Seeing Simon's blushing face made Vinny laugh softly.  "You boys always get up to no good when you put your heads together, don't you?" She asked, her gaze going up as Alvin sat down on the couch's arm in front of her, his legs parted so his cock could hang grrr

"W-Well, you know..." Simon started, pausing to clear his throat as he looked off to the side in order to not see Alvin's shaft. "Not always trouble, just... oddly entertaining situations with good outcomes."

Behind them, Theodore quickly made his move, crouching down so he could lap at Vinny's crotch fur first. His tongue immediately went to cleaning away any traces of soup he could find before grabbing her butt, spreading her cheeks apart and giving her asshole the same treatment. All the while, Theo kept her bushy tail off to the side, letting his tongue flick in and out of her tight back entrance. Vinny winced a little, biting down on her lip. "G-Gah… Theo, you don't have to- gmph!" She was interrupted by Alvin thrusting himself into her open mouth.

"Heh. No need to worry there, mom. He'll have you loosened up in no time." Alvin says, cupping her cheek softly as he started to thrust his hips slowly, working his length along her soft tongue. Sighing softly, Vinny nodded and closed her eyes, licking at the underside of Alvin's cock whenever he pushed into her.

Below her, Simon lined himself up with her folds, thrusting himself inside of her and arching his back. His face was in between her breasts, panting lightly against her cleavage as he started fucking, her weight and the couch beneath leaving him only able to make quick, rough thrusts. He even had a good view of Alvin hovering from above, watching his balls as they swayed back and forth while he had his way with Vinny's mouth. A sight that'd normally repulse him, but strangely didn't this time.

"Mmmpphh… Mmmm…Hhh!" The only sounds he could hear from their mother were her muffled moans, deep throated all the way. Some of her spit and Alvin's precum even dribbled from her mouth.

"Heh, gosh, you two are having fun already." Theodore comments, pulling back from Vinny's rear. He wiped his mouth on his paw, pausing to stare at her slightly glistening tailhole, nicely loosened and lubed with his drool. "My turn now!" He announced, gently straddling over Simon's legs as he took aim. With one swift motion, he was buried balls deep inside of her, grabbing the base of Vinny's tail and squeezing it tightly, unable to stop himself from moaning out. "G-Gah! No wonder Alvin spent so long last time getting you ready!" He gasped. Even after his best tongue work, Vinny still gripped his cock like a warm vice.

"Yeah, you're gonna have to be rough Theo." Alvin tells him, gently scratching behind Vinny's ear. "After all, mom gets tight reaaal fast~. Gotta power right through that." he moans, tilting his head back. Vinny moved a paw up, grabbing Alvin's rear and pulling his body closer, fitting every inch of his cock in her mouth easily, trailing her tongue up and down his length.

Taking his word, Theodore gently raised Vinny's hips, grunting softly in contrast to his harder motions. "Nnngh... a-alright mama, I'm not holding back!"  The soft slapping sounds filling the air as their bodies met only fueled everyone's desires as they indulged themselves with each others' bodies.

"Mmhf… Alvin, let him figure it out on his own…" Simon panted, having just finished cleaning the soup remnants from Vinny's chest area. It wasn't too long since the last time he was inside of her slit, but it certainly felt like a new experience all over again. Feeling a little more energized, he resumed to buck, thrusting all the way into his mother's moist cavern, dragging himself back out slowly before delving in again. "H-how am I doing, Mom?"

"Mmphh..mmmm…" Since her mouth was still full of Alvin's cock, Vinny gave her son a thumbs up, patting Simon on the chest to encourage him.

"Heh, what happened to learning on your own, Simon?" Alvin commented, the blush on his cheeks getting a little darker as he bowed down his head, his thrusts getting faster as he tried hilting into his mother's warm, welcoming maw. "Just d-do what feels good~!" With that, Alvin planted his paws down onto Vinny's back to support himself, one foot carefully draping over the back of the couch for leverage with his movements.

Theodore let out a little huff, gently pushing Alvin's paws aside before laying out on Vinny's back, panting against her fur as he picked up speed. "G-Guys... I know what I'm doing!" he whined. "I went first after all~"

Vinny's cheeks darkened as she listened to their banter. Even when rutting her like this, they managed to chat among themselves as usual. Something about it just excited her further.

"Gah… just remember that first isn't always the best." Simon huffed out. But he was soon finding that statement a little ironic, since his thighs were already slick and wet with his pre, mixed with his mother's juices - now trailing freely from her legs and slit. "Oh goshh…. Mom, I'm gonna shoot!"

Alvin blushed, picking up the pace as he bucked faster, deepthroating Vinny with all the force he could muster. "H-hey! You can't come first! I'm the oldest!"

"Says you!" panted Simon. "You're only older by five minutes!"

"Mmmm! Mmmphhh ffmmm!" Vinny's moans were intensified by all three sons now trying to be the first to reach his climax. Her mind was going cloudy, the mixture of their sounds and scents bringing her into a whirling haze of bliss, shown clearly by the increase of her own slick juices leaking out.

Theo, now trying to catch up, closed his eyes tight. "L-Last munk to cum has to clean it all up!" He moaned out, grabbing Vinny's butt and pulling her closer to him. "Gaaah… oh, gosh, mama… mamaaa!" he bit down on his lip, sneaking a paw around to rub on her belly.

Eyes widening, Vinny pushed against Alvin's hips, managing to get him to pull out as she grabbed his shaft, stroking him off rapidly. "B-Boys, it's not a contest!" She moans out loud. Her words fell on deaf ears, however, as her boys continued their rough poundings, panting and moaning away still.

Alvin then grabbed her shoulders, lifting her off of Simon enough to squeeze his shaft in between her breasts, humping away at her as he grit his teeth, tossing his head back enough to lose his cap. Alvin's toes curled against the couch as he adjusted himself, both feet at either side of Simon's head as he struggled to keep a good footing. "Nnngh… W-What's wrong with a little h-healthy competition, mom~?" He panted. "Gah, I'm gonna win anyway!"

Vinny opened her mouth to reply, only to squeak in surprise as Alvin suddenly let out a hot spurt of cum, splattering between her breasts first before the rest began to paint her face, all milky white. "Ohhh yeah, me fiiirst~!!"  Moaning out, Alvin took a step back, stroking himself through his climax while watching his spunk squirt all over her.  He tried his best to aim it mostly for her face, though a fair amount of his cum ended up on Vinny's breasts as well.  

"Aaahah…. Drink it all in, mom… that's what a winner tastes like~" he says, crouching down to kiss her lips.

"A-Alvin! Move your hips!" Simon growled. He wrinkled his nose as he tried looking away. Alvin's messy, softening cock was dangling by his nose, drooling leftover cum onto his face.  

"Mmm… suck it up, Si, I'm busy." Alvin responded, a sly grin on his face as he went back to kissing Vinny, his tongue poking in her mouth to explore. Letting out another growl, Simon reached up to grab Alvin's flaccid length, squeezing down on it as he tried focusing on thrusting, ignoring Alvin's muffled moan.

"Hnnh… Y-Yeah, Si, focus~!" Theodore moans out, his tail wagging eagerly as he leaned down, kissing Vinny's jizz coated cheek. "Or else you're gonna loo-oooose~" he added with a teasing hum.

"H-hey, cut it out!" gasped Alvin, a quick spurt leaking from his tip as Simon proceeded to lick him from the groin briefly. "That's not fair! I already won!"

"Sorry Alvin, but all's fair in…" Simon paused to catch his breath, before diving in to suck on his brother's length. He almost seemed to be enjoying the small meal of his brother's jizz as he lapped up what remained. 

Alvin scooted away from Vinny, now grabbing Simon's head and moaning, watching his little brother. "Haahh… Well, if you want your treat, you be a good boy and finish what you started!"

"Alvin, I'm not a dog-" Simon's words were cut short as he was muffled by his brother's cock humping into his mouth.

Theo, taking advantage of the distraction, quickly took hold of Vinny's waist. "Aah… I-I'm close!  I'm gonna cum all in your butt, mama!" He moaned, bucking his hips wildly in an attempt to drive himself over the edge.

"B-Better hurry and let it out, Simon." Vinny panted, putting her paws on his chest to keep herself steady against Theo's rough plowing. "He's gonna pop~"

As if on cue, Theodore hilted himself inside her butt, his back arching as he let out his last squeaky moan. He could already feel his first few spurts inside of her, then yanked himself from her hole, the remainder of his cum splattering on Vinny's butt, tail, and even some on her back.

"Oooohhh… Looks like you lost, Si!" Alvin says with a little smirk, ruflling his brother's head softly. "Which means you've gotta clean up~"

Simon didn't respond at first, only focusing on Alvin's shaft. Then, he suddenly pulled back, eyes going wide. "Ah! W-Wait, I was distracted!" He turned his eyes to Vinny, letting out a little whine. "C-Can't we go again?  That has to be against the rules!"

"Mmh… No way, Simon."' Theo says, gently nuzzling Vinny's back before sitting up, sighing as he spreads his legs.  "We never said we couldn't try messing up each other~"

"I'm sorry, Si, but I guess rules are rules." Vinny blushed, even under that milky white sheen on her face.

Pouting, Simon squirmed a little, crawling from under Vinny and sitting down on the floor. His cheeks darkened as he watched his family sit in front of him on the couch, the cum still lingering in their fur.

"You all suck." Simon mumbled.  With his face burning brightly with a blush, Simon crawled forward, setting his head between Theodore's thighs. He wrinkled his nose, starting by licking all over Theo's length, cleaning away his cum. 

Theodore tensed up, gasping as he shivered, slumping into the couch a little. "W-We didn't say you had to use your mouth… but it sure is nice that you are~"

Alvin watched them both, scratching his belly lazily. "Heh. I think he just wants to, Theo. Especially since he kinda threw the contest." With a yawn, Alvin snuggled closer to Vinny. "Think of it this way, Si. At least you already cleaned me~"

Shooting him a glare, Simon continued his work, quickly cleaning off Theodore's balls before moving over, now focusing on cleaning Alvin's seed from Vinny's face. She shuddered, purring at the feel of her son's tongue, lapping the jizz clean off and leaving a trail of saliva in its wake.

"Hey… this means that you didn't get to cum yet. I'm on it!" 

Before Simon could respond, Theodore was down between Simon's legs, eagerly latching onto his brother's cock as he licked up and down its length.

"Mmnh… T-Theodore…" Simon groaned, holding on to Vinny's shoulders for support. Of all people… he was getting a blowjob from his baby brother! Something in his mind was telling him to push away, but it was overpowered by the promise of a climax. He even paused his clean up job with Vinny, choosing to focus his attention on Theodore.

Alvin watched the two of them with a grin, climbing off the couch to grab Simon's tail and massaging it from base to tip and back, leaning in to nibble at Simon's back playfully. "Heh. Our Teddy's reeeeal good with his mouth, right Si?"

"Mmhf… Alvin, don't taunt me…" Simon huffs, his tail wiggling around in Alvin's hold. Vinny even joined in, rubbing her chest against Simon's belly while she started teasing his nipples with a few slow licks.

"It's okay to admit you enjoy it, Simon." She spoke, reaching around to grab his butt. "After all, Theodore is going out of his way to make you feel good, isn't he?"

Simon hesitated, biting his lip as he looked down, eyeing Theodore. "Mmf… a-are you sure about that…?"

"Well duh, of course!" Alvin piped in. "After all, it's only fair you get to cum hard too." Down below, Theodore nodded his head in agreement, taking a moment to release Simon's shaft with a quiet 'pop' sound.

"Hehe… plus I wouldn't mind having a taste of you," the youngesr chipmunk spoke, now stroking his big brother while his tongue went to lapping around his balls. "You're… mmmm - kinda nice!"

Simon moaned out again, his toes curling slightly on the floor. "Aah, y-you guys… I'm not gonna last…!"

A wild glimmer appeared in Alvin's eyes. "Hehe… But maybe that's what you want, don't you, Si?" With that thought in mind, Alvin even ducked his head down, stroking along Simon's tail like a second shaft while he dragged his tongue along his brother's butt cheeks.

"I h-hate you guys…" Simon's words were lost in a series of pleasure gasps. "B-But please… don't stop!" He moaned, his shaft pulsing wildly in Theodore's gentle hold. Despite his efforts to hold it in, his body's demands grew stronger than his brain was telling him to. Simon threw his head back, almost losing his glasses as he moaned at the top of his voice, his warm load of cum gushing out and splattering in Theodore's hair as well as on his face.

"Eeep!" The little chipmunk let out a tiny squeak; the force behind Simon's cumshot was enough to make him flinch. He quickly closed his mouth around Simon's shaft, letting the rest of his brother's load fill up before swallowing it noisily and happily. With his tail wagging around, Theodore wiped his lips clean, sitting back with a pleasant sigh. "Mmm… yummy!  Simon's doesn't have much of a taste... but what is there is kinda sweet!  Tiny bit bitter though."

Exhausted and well spent, Simon moved over to the couch, panting away. The sheen of sweat on his body made him look all slick, and Vinny was first to embrace him by nuzzling up to her son.

"Well… I can't say I expected things to turn out this way." Simon spoke when he finally caught his breath. Once he had recovered enough from his afterglow, he went back to licking at Vinny's face. They even shared a tender kiss or two, which Simon used to his full advantage to make his other brothers jealous. Once he finished with her face, Simon paused and scooted back to let her turn around.

"It's too bad we have to leave tomorrow though… We could have done a whole lot more with you, mama." Theodore spoke up, watching with jealousy as Simon went to cleaning up the mess on their mother's rump. 

Hearing that caused Alvin to bolt up in his spot. "Well, I'm sure we can work something out!" He says, arms crossed over his chest. "It's the first time in a long time we actually get to see mom, and we only get one itty bitty week? I dunno about you guys, but I'm not gonna stand for that!"

Vinny sighed, gently pushing Simon aside as she stood up, turning towards her room. "Boys… it's alright. Really." She started. "After all, it's better that you stay where you're most comfortable, right? Besides, I'm sure we'll be able to see each other again someday."

As she prepared to go, she was stopped by Theodore, grabbing hold of her tail. He hugged her firmly from behind, sniffing softly as he kept himself pressed against her. "I'll miss you…" he spoke quietly, soon joined in the hug by his older brothers.

"If… this really is the last time we'll see you for a while, then I think we should all sleep in the same room," Simon said. "And spend as much time together as we can tonight."

Wiping her face, Vinny wrapped her arms around them all with a little sigh. "Oh… my dear boys… please don't be sad." She spoke, "After all, I spent a good, long time with you three. My little lessons were alright for sex, but from what I've seen…" pausing, she smiled softly at the three of them. "You already know one of the most important things I could have taught you. Staying a family. Not just with your mates, but each other as well."

With that, she turned back to her room, leading the way in. "But… We have a big day tomorrow. Just give me a few minutes, and then you can come in to sleep, okay? You can help yourself to any of the food." She opened up the door, and then slipped inside, slowly closing it behind her and locking it.

Vinny sighed, her tail drooped down low, dragging along the floor as she went over to her bed, hopping in and turning her attention to the phone on her nightstand.

She hesitated at first, but soon reached over to pick it up, dialing a number in and holding it to her ear.

What would her boys think when they found out...? She shook out of her thoughts as she heard the "Hello?" from the other end.

"Hello? Dave? It's me again. I'm sorry for nagging about it but... Yes, yes, everything is fine here… The boys will be ready by tomorrow. I trust that everything went well on your end? Right... well, noon would be a good time. I'll see you then."
