Alvin opened the door and…

He wasn't expecting to see Theodore naked, of course. And perhaps Theodore didn't expect to see him just as bare.  

“Heyyy, uh… Theodore.  You don’t happen to have the phone, do you?”

“It’s downstairs… and I know what you were doing with it.” Theodore said softly.  “But how come you’re naked…?”

“Well uh-”

“Alvin, just let him in.  If he's naked then there's nothing much we can hide.” Simon's voice came from the bed.  “What do you need help with, Theodore?”

To that, Alvin crossed his arms some.  “Well aren't we suddenly open.”

Theodore walked in, fingers twiddling some as he made it to Alvin’s bed.  Seeing both of his brothers naked had him starting to get hard again… “Well… I think there's something wrong with my… thingy.”

Alvin closed the door, not bothering to lock it this time as he looked to his brothers.  While they talked, he couldn't help but be giddy on the inside.  Of course he knew Theodore was a chubby little butterball, but actually getting to see him naked made him squirm.  The rolls, the jiggling with each step, the innocent demeanor… 

He wanted him too.  

Alvin made his approach nice and slow.  Simon didn't say a thing, and Theodore didn't notice, not until Alvin was right behind him. 

“So it’s supposed to- E-Eep!!”  Theodore let out a loud squeal as his eyes went wide.  Alvin had grabbed his butt.

“Alvin!  We were talking!” Simon said with a glare.  “Let him go.”

“Awwwh c’mon!  You heard him Simon.  He wants to know what's up~” Alvin insisted with a smile.  “Isn't that right, Theodore?”

Put on the spot, Theodore timidly nodded, bringing his hands up to his chest.  “I-I just didn't want it to be anything b-bad, is all…” he looked up at Simon.  “It’s normal… right?  I’m supposed to make that sticky stuff?”

“That sticky stuff is your semen, Theo.  And yes, it is normal. Just try to not leave any stains where Dave might see next time.” Simon said as he sat up in his bed.  “And now on to you, Alvin.  Don’t think just because you got somewhere with me that you can take advantage of Theodore.”

“Take advantage…?  Simon, I’m shocked.  You know how I feel about you guys!” Alvin protested as he gave Theodore another grope.  Damn that squish was heavenly~. “If my little brother needs some… reassurance, then I’m not gonna pass on the chance to give it to him.”

Simon just rolled his eyes.  “Honestly Alvin, what are we even gonna do?”

“Hmm…” Alvin took a moment to think.  There was so much he wanted to do to Theodore… “Well, I think I have an idea.”  He turned Theodore around to look him right in the eyes.  “Wanna feel reeeeally good, Theo?”

“I-I think I do.” 

Alvin smiled at that, patting Theodore on the head.  “That’s the spirit!  So, you’re gonna climb up on the bed, and just lay out on your belly.  I’ll take over after that~” He hummed, his cock already starting to harden from his own thoughts.  

“Wait, why on my bed?” Simon asked, though Theo climbed up regardless as Alvin said.  Simon sighed, looking down to pat his little brother on the head.  “Well… I guess this won’t be so bad if we’re helping you out.”

“Hey Simon?  Those stories… we’ve never done that kind of stuff.” Theodore started.  “Is that really what the fans think we do?” 

“Looks like that’s the case, Theodore.  And I guess we’re going to be proving them right soon…” Simon said as he scooted closer to him.  

Alvin let out an eager coo as he put his paws on Theodore’s butt, spreading those cheeks apart slowly.  There it was… Theodore looked even tighter than Simon did~  He couldn’t stop himself from pressing his nose right up on Theodore’s hole, causing the pudgy munk to squeal out again.  Just as he did with Simon, Alvin took in several deep sniffs, burying his nose in as much as he could.  Theodore didn’t have the same musk as Simon, but what he did have was something more… untouched.  

Even when Theodore was squirming, Alvin held tight, beginning to drool again from the smell alone.  “Ohhhh yeah… that’s the stuuuff~”. Alvin peeked up with a grin. “Hey Si… use his mouth while I use mine~”

“W-Why’s he sniffing my butt?” Theodore asked as Simon moved in front of him.  The taller munk just rolled his eyes. “It’s one of the many things that makes him feel good.  Don't worry.”

Seeing Simon’s crotch put a brighter blush on Theodore’s face.  It was all right there, and his cock seemed to be getting harder to.  “Uh… s-so what about you?”

“Just open your mouth, Theo.” Simon instructed.  He didn't plan on it at all today… and now here he was, holding his penis and aiming it for Theodore’s lips.  “Regardless… open your mouth for me.”

Theo did open his mouth, but he ended up letting out a moan as soon as he did.  “A-Alvin!  Don’t lick there, it’s- Mmf!”  He was quieted by Simon’s shaft pushing into his mouth.  It almost touched his throat, but Simon held back from going in fully.  He looked up in confusion, but hearing Simon moaning told him everything.  Using his mouth was a good thing.  

“That’s it.. suck him off, Theo.” Alvin cooed as he gave Theodore’s hole another slow lick, getting that rim completely covered in his drool.  What a taste… intoxicating… Alvin pushed his tongue against Theo’s rim, letting out a low groan when his tongue breached it.  He wriggled it around, pushing against the incredible tightness of those untouched walls.  

All for him to lay claim to… 

It helped that he got the show of Simon getting his cock sucked.  And he got to relish in all of Theodore’s precious moans.  It was all making him even harder~  Alvin ended up slapping Theodore’s butt, having those cheeks wobble up against his face as he shoved his tongue in all the way.  

“Ghnnnmh!”

“A-Alvin, don’t distract him.  He’s doing… aaah, very well up here.”

Now, feeling Theodore’s hole was prepped enough, Alvin got up to straddle Theodore’s thighs, aiming the tip of his dick to that hole.  “I’m gonna go gentle on you… or at least try to.  So don't freak out~”

As Alvin pushed his way in, Theodore let out a muffled whimper around Simon’s cock. It felt weird.  Like stretching… but only on the inside.  He would have looked back, but Simon had his hands on his cheeks now.  

“Relax, Theodore… you’re going to be alright.”  Simon told him as he stroked his cheeks.  Being on the giving end was probably more his speed anyway.  Simon started moving his hips, keeping his hold on Theodore’s face all the while. “Ohh yes… just stay exactly like that.”

“Hehe… well look at you, Simon. What happened to “don’t take advantage of him”?  Looks to me like you're doing just that~” Alvin teased in between his thrusts.  Theodore’s walls were squeezing on him even more than Simon did!  With both paws atop Theo’s butt, Alvin grit his teeth as he picked up his pace. “Jeez, he’s gripping s-so hard… it’s tough to keep going~”

Simon let out a little huff. “Just watch how far you go.  We don't want to overwhelm him.”

“Says the guy who’s about to be balls deep in his mouth.”  Alvin put a hand to the back of Theodore’s head, getting a good hold in his brother’s hair.  “Gotta get to the base, Theo.  Deep breath~”

“Alvin don’t you- Hnnnnngh!!” Simon gasped, gritting his teeth as the pleasure shot straight up his spine. Alvin had pushed Theodore further, and Simon felt his tip jab at the back of his little brother's throat. Theodore audibly gagged, And Simon had to move Alvin’s paw. “You’re gonna choke him!”

“Oh come on Si, it was just a little gag!  Look, he’s even staying down on his own.”

Simon rolling his eyes, looked down at Theodore as he pulled back, only keeping half of his shaft in.  “Then he can go back down when he’s ready.  For now, he can keep his tongue at the head.”

 Between them, Theodore just did his best to make them both feel good.  Simon said something about the head… and Alvin's moans got louder whenever he tensed up.  It was all too much for him to handle.  Theodore tried to raise himself up, but then Alvin did something that made Theodore see spots for a moment.  His cock had rammed up against something within him.  The shock of pleasure he got was almost as good as when he squirted that stuff on the seat.  

But Alvin just had to hit it again.  On the fourth hit, Theodore moaned loudly around Simon’s dick as his body locked up. Again, he was squirting, his hips bucking against the bed nonstop as he hit his orgasm, riding it out and bouncing his butt up against Alvin’s hips.  “MNNNNMHH!!” 

“F-Fuck, that's tight!” Alvin yelped, unable to bury himself any further.  Theodore's constant moving was doing more than enough, but the way his shaft was being squeezed and milked neatly caused him to cum as well. “Theo!  Theodore, let go!”

No response.  All he got was more of Theodore pushing against him, wiggling his hips side to side while drooling on Simon’s dick.  

With a loud groan, and a few more attempts, Alvin finally managed to pull out of Theodore, panting heavily as he sat back on the bed.  “J-Jeez… how come you didn't do anything like that, Si?”

Simon also didn't respond to him.  However, he was busy with holding Theodore’s head in place, moaning away.  He had to admit… for his first time, Theodore was getting close to bringing him over the edge. “Because… hnnn…”

“Real helpful…” Alvin mumbled as he watched his brothers.  He grabbed his shaft and started jerking, keeping an eye on Theodore's ass the whole time.  “Don’t think I’m done with you…”

“N-Nnmh…” Theodore's gaze went up towards Simon’s face.  The throes of orgasm were fading back to tingles, but now he was clenching on nothing. He made such a mess on his belly...  He let out a whine, releasing Simon’s cock.  “Hah, haah… Alvin, please… I want more… more of that…”

He reached behind himself, spreading apart his butt cheeks as he rolled over on his back.  “Pleeease… that spot felt s-so good!  I wanna feel it more, Alvin!  P-Please!”

“...you have no idea how long I’ve wanted to hear you say that.” Alvin was grinning again, moving back to Theodore as he took hold of his baby brother’s legs.  “Fine.  But this time, I’m not stopping just because you cum.  If you tighten up, I’m ramming straight through~”

“Alvin, I still have to-”

“Aaaahh!  A-Alviiiin!” Theodore squealed as he was entered again, his toes curling tight in the air as Alvin rammed at his butt.  He didn't mean to interrupt Simon, but he couldn't stop himself.  The spot was being hit every time Alvin went back inside of him, and he felt his own cock begin twitching again.  “Oh my gosh, w-what is thaaaaat…”

Simon, lining his shaft up with Theodore’s mouth again, quickly thrust back down into his maw.  “Ngh!  It seems… Alvin’s hitting your prostate… just b-bear it, the intense pleasure is natural… and keep moaning.” Simon let out a huff as he started humping away at Theodore’s face again.  He would have preferred taking his time, but Alvin was going to drive Theodore insane at this rate.  He had to at least peak once before that could happen again.

To think he would have found himself indulging like this… those stories now had merit to them.  Simon put his paws down on Theodore’s chest, ignoring that thought as he worked himself towards his finish.  

“Hey Si… feel like doing o-one more thing I like to think about?”

“Alviiiin…”

“No really!  It won’t distract you, I bet.”

Simon sighed.  Going back and forth with Alvin while they were doing this to Theodore.. “Fine, make it quick.  I’m getting clo-”

He went quiet as Alvin’s lips met his.   And it was a deliberate kiss, one that Alvin even held him in tight.  Simon’s eyes went wide, but Alvin’s were closed.  He could feel Alvin’s tongue poking at his front teeth.  Surely, he was stunned.  A kiss of any kind coming from Alvin was a shock.

While Simon was distracted, Alvin continued to pound Theodore.  The kiss was better than he expected.  Simon was actually staying in instead of the expected rejection… And his lips were soooo soft against his tongue… Alvin, holding on to Theodore’s waist, gave a firm thrust forward.  The urge was there.  That last thrust had him completely buried within his little brother, and Alvin felt his cum spurting deep inside while he moaned right into Simon’s mouth.
 
Sharing such a deep kiss with his own brother… their tongues brushing against each other while swapping spit… It didn’t sound tempting at first, but the more Simon allowed his guard to drop, he actually found it to be quite… liberating. He could even feel the tremors that went through Alvin’s body when he came. 

Simon was brought out his thoughts when he heard Theodore gag again.  Poor pudge of a munk was trying to fit more of him in again… Simon sighed through the kiss before he broke it.  Alvin  started whining, but Simon shook his head.  “Let me finish…”

Alvin sat back with a little pout, but watched the show anyway.   At least now he got to see his younger brothers enjoying each other.  Theodore’s moans were still muffled, but his cock was standing hard af attention yet again.  And Simon, even with his head bowed, was still loud enough for Alvin to hear as he humped.

Not wanting to miss out, though, Alvin turned his attention to Theodore's pulsating length.  “You know… I always wondered…” he muttered, lowering himself down to Theo’s crotch.  He looked like he'd burst any second now.  First, clean up.  Alvin started to lick through Theodore’s fur.  His tongue trailed through, gathering up the cum that was released.  Of course it had a sweet tinge to it.  Alvin murred, closing his eyes as he moved up along the trails left behind, even when Theo started squirming from it.

Then, once the mess was gone, Alvin wasted no time in taking in Thedore’s cock and immediately started to suckle on it.  Those moans got louder, and Theodore even tried to pull back from him, but Alvin was stubbornly holding that dick in his mouth.  He even pushed his paws against Theodore’s waist so he couldn’t move from the bed.  Alvin bobbed his head on Theo’s shaft, savoring his taste and texture up against his tongue.  

Good thing Theodore wasn't too big.  Alvin got to lavish his entire shaft with ease~  He turned his gaze up to the show, swaying his butt a little when he saw Simon was watching.  

Simon was quick to look away, focusing on getting himself to his peak.  “Gnnh… Theodore… I’m gonna cum.” He warned, looking down at Theodore.  He was doing his best to nod his head, so Simon pushed himself all the way into Theo’s mouth.  With grit teeth, he stayed down there,  having Theodore’s tongue working along the top of his dick.  “A-Aah, aaaahhhn…!”  Simon closed his eyes tight, his balls hitting against Theodore’s nose as he shoved himself in all the way, the heat of his orgasm filling his entire body as he started to release in Theodore’s mouth.  

“Ghkk!!” Theodore’s eyes went wide from that.  Simon’s tip was so close to his throat, most of his cum was going straight down.  And Alvin was sucking on his shaft too!  He let out a loud whine as his toes curled up, paws pushing against Simon’s hips as he felt another orgasm coming on.  

“Ah, s-sorry Theodore…” Simon muttered as he pulled out of Theo’s mouth, the rest of his cum now splattering all over Theodore’s face.  

“Hnnnn!  Oh gosh, Alvin, oh f-fuck!!” Theodore squealed out as his third orgasm of the day tore through him, making him quake and tremble against the bed as his shaft gave up whatever weak squirts it still had to offer.  He covered up his mouth, both to muffle his moan and to act as if he hadn’t sworn.  

Simon sighed, reaching down to pat Theodore’s head, comforting him through his rough climax.  “It’s okay… it’s alright.  No one’s gonna tell Dave.” He promised, cupping Theodore’s cheeks.  “I’ll get you a towel.”

“Mmm… no need~” Alvin growled as he finished cleaning Theo’s crotch and belly, now crawling up to start licking Simon’s cum off of his baby brother’s face.  “Hehe, you’re so cuuuute when you cum… and you’re starting to get a sailor mouth~!”

Theo let out a little whimper in his state of afterglow, not even bothered by Alvin’s tongue being that close to his lips.  “I-I didn’t mean to… it just slipped out…”

Grinning, Alvin deliberately dragged his tongue across Theodore’s mouth, giving him a quick kiss in the process.  “Mmmm, doesn’t matter.  It happened~” He cooed before letting out a soft sigh, resting his head down on Theodore’s chest.  

“Guys…?  Are we, uh… always gonna do stuff like this?” Theodore asked as he felt a new blush coming on.  “I think I really… really liked this.”

Alvin traded glances with Simon.  “Well…?  What do you say, Si?” he asked.  “I know it was sudden but I think we could-”

“Yes, Alvin.” Simon interrupted him.  “At this point, I’d be crazy to turn down an offer like this.” Simon moved himself so he was laying down next to his brothers as well.  “Besides… it’d be a shame to miss out on knowing you two more.”

The news made Theodore smile, pulling both Alvin and Simon into a tight hug.  However, Alvin may have been the one smiling most.  

“So tell me, Alvin.  How do you two plan on my blankets getting clean after this?” Simon asked with a smile as he leaned into their shared embrace.  

“Pfff.  Come now, Simon.  You know things are gonna get more messy before it’s time to clean~” Alvin responded.  Though, then, he ended up letting out a wide yawn. “Just… after… a lil’ nap…” He muttered as he let his eyes close.
