Fan Fiction Friday: Alvin and the Chipmunks in “Comfort”


I actually found today’s FFF entry a while ago, but then had it sent to me by Topless Roboteer Lucy D. — which is a pretty good sign I need to run it. It’s a story by the author Smitty91, who seems to have a thing for chipmunks — at least, Alvin and the Chipunks. He’s written 15 stories for the trio, many of which aren’t erotic/inappropriate/perverted at all — of course, some of them are over 10,000 words, which may indicate an unhealthy obsession with Alvin, Simon and Theodore on its own. However, this story is definitely erotic/inappropriate/perverted, and it also happens to be one of the ones over 10,000 words long. I have chosen to examine one section, pretty much in the middle. Here’s what you need to know to get up to speed:

? Alvin has broken up with a girl from school, who I believe was a human. He’s been crying and depressed for two days.
? Over those two days, he has comforted himself with food. He is now hella fat.
? Simon has come in to check on his brother, which immediately turns romantic.
? Alvin also drinks milk from a baby bottle.
And now, the discomfort begins…

“Say, Alvin, you still wouldn’t happen to be hungry, would you?”

Alvin chuckled as he patted his enormous stomach. He couldn’t imagine how he could still be hungry, and he highly doubted he could eat anymore chocolate or peanut butter. Yet, in his mind a voice was screaming for him to allow Simon to feed him as much food as possible. He wondered if maybe in his gluttonous overeating over the past few hours had caused him to lose control over his appetite. He fought with what to do and before what he realized what he was doing, he was nodding his head in agreement to Simon’s question.

Simon smiled with glee as Alvin nodded. “Great,” he cried, clapping his paws together. “You just stay right there, don’t move.” He darted over to the side of the bed and piled the boxes of chocolate, jars of peanut butter, and cans of Mountain Dew onto the bed, leaving very little room for the two of them. Just as quickly, he found himself hovering a chocolate over Alvin’s mouth, smiling at the eager chipmunk below him, licking his lips and kicking his legs while his tail swayed back and forth very much like a dog’s. “Open up.” As soon as his older brother opened his mouth, he shoved the chocolate in. “Ah-ah-ah,” he scolded Alvin when the fat chipmunk began to chew. “Don’t eat ’em just yet.” He dumped several chocolates into a waiting paw. “I wanna see how many of these babies I can stuff in your mouth first.” Out of the corner of his eye, he could clearly see that Alvin loved the idea simply by the sudden change of pace of his wagging tail.

It seemed Alvin could fit several chocolates in his mouth. This wasn’t too surprising. After all, they were chipmunks and they belonged to the rodentia family, and anyone who knew animals from this family will know that they have quite a knack for stuffing their cheeks with food. Their rodent cousin squirrels were very good at this feat as well. 

I’m not a religious person, but if anybody’s religion has a special hell for fan fic writers who anthropomorphize animals but then pretend like they still have basic animal characteristic of their species, let me know, because I’m signing up. Point is, once you have a chipmunk talking, wearing t-shirts and engaging in an infantilism fetish, you have renounced their right to portral them as the animals they’re based on.

By the time Alvin was allowed to eat the chocolates in his mouth, Simon had successfully crammed a total of fifty chocolates in the chipmunk’s mouth. When he did swallow the fattening treats it seemed as if his stomach doubled in size as a direct result, if at all possible. His stomach was so big and round beforehand that neither one of them saw how it could possibly hold much more food.

One more meent, monsieur cheepmunk. Eet ees… wafer thin.

Simon lovingly patted Alvin’s belly and gave the chipmunk a smile. “Good boy, Alvin.” He reached up and ruffled the fur on Alvin’s head. “You want more?” He laughed when Alvin gave a vigorous nod of the head, his head looking like it was on a spring. “Well, okay.” A bulb went off in his head and his smile widened. “What say we do something different this time?” Alvin gave him a confused look, prompting him to explain further. “Just trust me on this, Alvin. You’re going to enjoy this.”

Alvin nodded.

“I feel like having some peanut butter,” Simon declared. “Would, uh, you mind rolling over onto your stomach for me?”

I’ll take “Questions you never want to hear after someone says ‘I feel like having some peanut butter'” for $400, Alex.

Alvin gave his brother a puzzled look, but nonetheless did as he was told. He had no idea how him lying on his stomach and peanut butter went hand-in-hand. He assumed that Simon must have had some scheme up his sleeve. This he found odd, but interesting, seeing as it was usually him who came up with the scheme.

So if Alvin’s turned into the fat one, and Simon’s now coming up with the schemes, does that mean Theodore has become the smart one by default? Does that mean he walked in on his brothers making out and Alvin sucking a baby bottle, backed out slowly, and immediately caught a cab to the airport? Because I think that’s be the smart thing to do.

“Good,” Simon remarked. “Now just-” He stopped momentarily to stare at how big and round Alvin’s behind had gotten over the past few hours.

Turning his head, Alvin noticed his brother’s odd reaction. Laughing, he said, “It’s enormous, I know.”

“Yeah,” Simon agreed, nervously rubbing his neck and letting out a soft chuckle, “but I like it.”

Simon cannot lie.

Alvin looked back at Simon, a surprised look on his face. “Really? You do?”
Simon nodded his head. “Yeah, I do. I really, really do. Now, uh, just-just hold still.”
Alvin rested his head on the pillow in front of him. He inhaled the fresh scent of fabric softener, a scent that he had come to love.


Simon reached across the bed and picked up a jar of peanut butter. Taking a moment to examine the brand name, he unscrewed the blue top and tossed it over his shoulder. With a clatter, it landed on the floor. Smiling, he dipped his entire paw in the brown substance and went down until it was completely covered in peanut butter. Bringing his paw up to his nose he took a moment to indulge in the rich scent of the food before reaching forward and applying it to Alvin’s butt.

Alvin flinched as he felt something soft caressing his behind, but he couldn’t deny the fact that he was enjoying it. Still, he couldn’t help but wonder what his brother was up to. Turning his head around, he demanded, “Simon, just what do you think you’re-”
Simon shushed him. “Just relax, Alvin. Come on, tell me you’re not enjoying this already.”
Alvin laughed. “Actually, to be perfectly honest, I am.”

So… does getting your ass covered with peanut putter somehow fall into the weight gain or infantilism fetishes? I mean, if you have one of those fetishes, are you like, “Peanut butter on my butt? Yes, please!” Or is this like a completely new third feitsh? Is there a grown man, wearping a diaper and bib, reading this from his specially made reinforced playpen, and saying to himself,” Peanut butter? On his ass? What a weirdo. Hey, where’s my pacifier?”

Simon smiled. “Good.” Once he had a thick layer of peanut butter covering Alvin’s rear, he set the jar aside and shoved his paw in his mouth, licking up the remains of peanut butter with his paw. A shiver ran down his spine as he allowed his tongue to caress every inch of his paw: the tips of his fingers, between his fingers, the palm of his paw, and the back of his paw. He finally pulled it out, smiling at the glistening saliva that covered it. He moved forward, his paws gripping Alvin’s fat hips. “Okay, you ready?”

“Just what exactly are you planning to do?” Alvin inquired, looking over the big hill that was his back at his brother.

“Let’s just say… it’s peanut butter jelly time.”

Simon chuckled. “Just relax and leave everything to me.”

Alvin nodded. “All right, Simon. After all, you are the smart one.”

Alvin, Simon has just covered your ass in peanut butter. It might be time to realize “the smart one” is only relative to you three chipmunks.

Simon thought about correcting the chipmunk. He wanted to tell Alvin that he was just as smart as himself. Since Friday, Alvin had been beating himself up over how stupid he was to believe that such a girl like Terri could ever love someone like him. When Simon had tried to confront him about his negative thinking, the chipmunk had refused to listen to reason, much less anything else that Simon or anyone else had had to say. Hopefully by the end of the afternoon, Simon will have changed that.

Yeah, nothing builds self-esteem like getting super fat, drinking milk from a baby bottle, and having a family member eat peanut butter out of your asshole.

With his tongue flicking in and out of his mouth, Simon brought his face closer and closer toward Alvin’s peanut-butter-covered butt. The scent was enough to make him want to start licking like mad. He restrained himself, however. He would start out at a slow pace and if Alvin appeared to like it, he would go faster. For the time being, however, he would have to see whether or not Alvin was comfortable with the activity. He suddenly stopped when Alvin raised his rump, now with his legs fully erect but with his lower body still lowered. He pressed onward, his eager tongue moving in and out of his tongue. Finally, his tongue made contact.

At first, Alvin flinched, tightly gripping the comforter of his bed as he felt Simon’s tongue pass over his buttocks, cleaning off the peanut butter that covered it. He quickly began to relax, getting used to the feel of his brother’s tongue gently caressing his behind. Sighing, he rested his head back on the pillow, allowing his brother to clean him up. He noticed that Simon was idly taking his time with the process, obviously wanting him to enjoy it as much as possible.

Reaching up with a paw, Simon gently pushed Alvin’s tail back so that it rested along his back, making sure that it was out of the way so that it wouldn’t obstruct his concentration. His hot breath became quick and heavy as the process went on, and he imagined that Alvin was enjoying it just as much as he was the licking. Hearing a moan of pleasure come from his brother, he momentarily lifted his gaze to smile at him, then closed his eyes once more as he kept rimming his brother, clearing away the peanut butter that coated it. He only opened his eyes every now and then to look for areas in which he had missed the peanut butter entirely. Eventually, he pulled away from his brother’s rear end, having cleared away all of the brown substance. He wiped his mouth on the back of his paw and couldn’t stop himself from beaming at his brother’s enormous, round furry behind. “I’m done.”

As he rolled over onto his back, Alvin let out a groan of disappointment. “Already?” he asked, smiling at his brother.

Simon smiled back. “‘Fraid so,” he remarked.

“Hmm,” Alvin mumbled.

“You know what’s weird, though?” asked Simon. “The peanut butter says it’s creamy, but when I was eating out of your asshole, there were definitely chunks in there!”

“Huh,” said Alvin nervously. “Th-that is weird.”

Simon crawled over and lied down on top of Alvin, gently kissing him. He ran a paw up Alvin’s chest until he felt his fingertips caress Alvin’s own. He felt Alvin curl his fingers around the openings between his fingers and close in around them, holding his paw tight. Pulling away from his brother, he asked, “Nervous?”

Alvin nodded.


Alvin nodded once more.


Alvin nodded.

“Worried that what we’re doing in an abomination in the eyes of god, man and chipmunk?”

Alvin just kept nodding.

Simon leaned down and kissed his brother once more. “Don’t worry; I won’t hurt you.”
Alvin’s trademark mischievous grin played across his lips. “We could get caught, you know, fooling around like this?”

Simon allowed a smile to come across his own face as well. “I know, that’s what makes it fun. Am I right?”

Laughing, Alvin nodded his head.

The worst part is you just know that if Dave Seville came home to find two of his chipmunks in incestuous mid-coitus, no matter what punishment he’d dole out, he would begin by screaming “AAAALLLLLLLVVVIIIIIIINNNNNNNNNNNNN!!!!!!!” at the top of his lungs.

“But you make a very good point, Alvin. Excuse me a minute, would you?”

“Sure,” Alvin remarked.

Simon, much to his reluctance, got off Alvin and scampered across the room over to the bedroom door. Gripping the doorframe, he closed it until he heard a snap. Afterwards, he scampered up the dresser that was beside the door and leaned forward until he felt his paw close around the handle of the deadbolt. He turned the handle upwards, locking the door. Smiling at Alvin from across the room, he bolted down to the floor and before long found himself back on top of Alvin, kissing him. “Like I said, Alvin, I’m not going to hurt you, and I don’t you to do something that you don’t want to.”

Alvin shook his head. “No, I want to do this,” he corrected his brother. “I need it.”

You need food and air, Alvin. You do not need to be buttmunked by your brother because a girl didn’t like you.

Simon nodded. “Okay, Alvin.” He leaned down once more and planted yet another kiss on his brother’s soft lips.

Breathing in through his nose, Alvin pulled Simon close. He held Simon’s head but quickly felt his fingertips leaving that one specific area and trailing down Simon’s striped back until he reached the base of his brother’s tail. Smiling, he ran his fingers further down south until he began caressing the fur on his brother’s buttocks. Hearing a moan of lust from Simon only caused him to go further and he slowly one of his fingers into Simon’s butthole.

Just like an anthropomorphic chipmunk! No foreplay, just straight for the asshole.

Simon gasped at the sudden object intruding him. Sighing, he quickly relaxed, resting his head on Alvin’s chest and allowing his older brother to please him. Sudden movement from Alvin, however, caused him to raise his head. Noticing that Alvin was trying to roll over onto his stomach, he slid off Alvin and waited patiently for Alvin to get rearranged. He smiled as Alvin wiggled his butt, smiling at him and looking over at him out of the corner of his eye. “What, you want more?”


“Is that a bad thing?” Alvin questioned.

Simon didn’t object. He swept several of the items to the floor, thus making much more room for the two of them. He quickly crawled over to where his brother’s butt was raised in the air and examined it for a moment or two before climbing on top of Alvin, making sure that his member was directly aimed at Alvin’s entrance. “You ready?” A nod of the nod confirmed this. “Okay, here I go.”

Oh. Phew! That’s a reli–

“Just be sure to go slow at first, okay?”

“I know.” Slowly, he edged his penis towards Alvin’s entrance, going slow at first to tease his brother. As the tip of his erect member bumped into the hole, he looked up at Alvin. The fat chipmunk did not much as whimper. He did, though, when Simon entered his member halfway into him. “Sorry, I’m not hurting you, am I?”

“Physically? A little. Mentally? No words can express my damage occurring to my psyche right now.”

“No,” Alvin replied, “not at all.”

Simon nodded and went back to work. He heard several pained gasps escape Alvin’s throat, though he knew that the overweight chipmunk was trying his best to make them inaudible by muffling them into the pillow. He continued to ease in and out of Alvin at a slow pace until the chipmunk got used to the sensations. Once he did, he increased his pace. He leaned forward until his body was adjacent with Alvin’s, wrapping his arms tightly around Alvin’s thick waist, hugging his brother tightly while he planted kisses here and there between the fat chipmunk’s ears, ruffling the fur there. He smiled when Alvin’s ears gave a slight twitch as his lips caressed their tips. “Just relax,” he breathed into Alvin’s ears, his breathing heavy as he panted. “It’ll ease the pain.”

Please remember: This isn’t just a story about Simon the chipmunk fucking his brother Alvin — it’s a story about Simon the chipmunk fucking his brother Alvin who’s super-fat. And whose ass probably still has some peanut butter on it.

Alvin nodded and slowly began to feel the muscles in his buttocks relaxing. He quickly found that Simon was right; relaxing did make the experience more pleasurable. He quickly found himself rearing his head back and letting out loud moans of pleasure as his younger brother continued to thrust in and out of him. “Hard and fast now, love,” he panted.

“Your wish is my pleasure,” Simon replied, smiling. Grunting, he increased his pace, shoving his erect cock as fast and as hard into Alvin as the fat chipmunk could handle. His efforts proved to be working, for he heard a high-pitched squeal of delight erupt from Alvin’s mouth in doing so.


Alvin squeezed his eye shot, his body overtaken by the pleasant sensations that were driving his senses wild! His tail beat frantically against Simon’s chest and his breathing matched Simon’s almost identically. He tightly gripped the pillow, a high-pitched moan or squeal making its presence known. Seeing as they were home alone and since the neighborhood was dormant until late afternoon, he had no worries of what they were doing behind closed doors being known. “Oh, God, Simon . . .”

“Say my name,” Simon panted. “Say my name!”

“Simon! Simon! Now say what I want for Christmas!” shouted Alvin.

“You! Still want!! A hula hoop!” screamed Simon in ecstasy.

Screams of pleasure filled the room from both boys as the taller one continued to work, filling up the fatter one in the most pleasurable way possible. Their backs arched, their heads reared back, and their tails beat wildly at the air as they were both overtaken by desire and warmth.

Are they not worried about Theodore hearing them? Do they not care? Maybe Theodore is in his bed, under the covers, weeping uncontrollably at the unspeakable horror and perversity going on in the next room. It’s what I would be doing. Well, that or setting chipmunk traps.

Gasping and panting, Simon rested his head along Alvin’s. He could feel pressure building in his loins and he knew that the timing was imminent for him to relieve himself. “Get ready, Alvin,” he whispered in his brother’s ear through heavy breath. “I’m almost there.”

Alvin said nothing in response, but a whimper of discomfort told Simon that the older chipmunk was displeased at having the activity stop at such a short time. 

Oh no! Now’s Alvin’s going to get so depressed again he’s going to need to get fucked by Theodore!

Simon himself regretted that their steamy session had to be cut so short. Still, he held back his seed for as long as possible before he could no longer stand it any longer. Screaming in delight, he released his seed into Alvin’s butt. He lowered his head and bit down on Alvin’s neck to contain the glass-shattering scream of pleasure that he so desperately wanted to be known to the world.

The Chipmunks - Urban Chipmunk.jpeg


Alvin reared back his head and let out a high-pitched yell as he felt Simon’s spooge stream into him full-force. It was only afterward that he rested his head back on his pillow, panting with Simon’s sharp canines sunk into the flesh of his neck. He found it odd that he didn’t mind at all.

As horrible as this paragraph, I can’t helped but wonder what a high-pitched yell by a chipmunk would sound like. I assume only dogs could hear it.

Simon removed his member from Alvin, hearing the chipmunk give a groan of disappointment as he did so. 

toht face melting.jpg

The allowed the cum-covered tip of his cock to guide along Alvin’s rear end, spreading his semen across it so he had a reason to clean Alvin up afterwards, though he was sure that the chipmunk’s entrance needed some cleaning as well. 

toht face melting.jpg

Reluctantly, he slid over to the side until he was lying on his back, his gaze towards the ceiling, his erect cock resting along his stomach. He smiled as he felt Alvin plant a kiss on his cheek.

toht face melting.jpg

“Mm, that was wonderful, Simon,” the fat chipmunk stated, resting his head on his younger brother’s chest. He felt Simon place a paw on his back and begin to rub it affectionately.

Simon gave a weak laugh, still trying to catch his breath. “Who says it has to end after I climax?”

I DO. I SAY IT HAS TO END. The story does continue — again, this is only a 3,000 word segment of a story that’s over 10,000 word of chipmunk perversion, incest and insanity. Feel free to read it all if you hate yourself that much. Now if you’ll excuse me, I seriously need to set chipmunk traps all around my yard. I’m told the best bait to use is peanut butter and gay chipmunk pornography.
