Breeding Like Rats

Monroe frantically piled up clothes beside his open suitcase, groaning and rubbing his temple as he tried to rack his brain trying to remember everything he needed to pack up. The 18 year old rat boy silently cursed himself for once again leaving crucial tasks until the very last moment, hurriedly stuffing the suitcase full. He took one last look around his room to see if he was missing anything he ought to bring along to the trip, peeking inside of his bedside table. Staring up at him was a half used pack of condoms, the boy stopping for a moment as he thought about grabbing a few, just in case. He and his mother were on their way to spend the holiday week in a large cabin in the middle of the woods, the pair joined by a few other families and friends. Monroe knew a few of the other people who would be staying with them, including a couple of quite cute girls. He'd had a spot of bad luck in the relationship circuit recently, breaking up with his girlfriend only about a month back, leaving him rather pent up. The rodent heard a car honking its horn outside, his mom calling up to him a few seconds later, 
"Monroe? The van just arrived, are ya done packing up?" 
"Uh… yep! All done, I'll be down in just a second!" 
He grabbed a handful of condoms, slipping them into one of the suitcase's pockets before zipping it closed and picking it up, grunting quietly as he heaved it downstairs. Waiting for him at the bottom of the stairs was Helen, the rat smirking slightly as she watched her son struggle with his luggage, 
"I hope you know that I'm definitely not carrying your bags, I did tell you to pack light so you can't say that I didn't warn you." 
The two laughed, her sinewy tail moving to keep her balance as she leaned down to pick up her own, considerably lighter, suitcase. Helen was almost 30 years older than her kid, a tiny hint of white visible on her grey fur. Her long hair was still as brilliant red as always however, wonderful shades of crimson glimmering in the light. Monroe swore that she dyed her hair, though he never could get her to admit to that. She was also on the curvier side of things, the outline of her thick thighs and her wonderfully hefty ass showing through her sweatpants. The van honked its horn once again, Helen nodding towards the door, 
"Alright, let's head out before they abandon us here."

The two rats stuffed their suitcases into the back of the van before hopping inside as well, the duo greeted by the canine who was driving. The group set off, heading out of the city, the van joined by another car with the rest of the group in it a little ways down the road. Helen leaned back and sighed gently, closing her eyes as she relaxed and let her head sink into the headrest, trying to get her mind to calm down and get into the proper mood for a holiday. She had been particularly busy with her work in the last few weeks, a hectic flood of sudden incoming clients combining with a wave of staff taking the holiday off of work. In addition to work related issues, the rodent's family life hadn't all been calm waters either, a semi recent fight with her husband resulting in the two giving each other some distance to cool off and think about the future, a complete split even being discussed. In his absence, Helen had started to feel rather lonely, though Monroe had helped in that regard quite a bit. The boy had moved back in with her about half a year ago, to help cut back in living expenses while he studied. Living with him made the mother start to feel very nostalgic, fond memories of his childhood flooding back into her mind: playing hide and seek in the backyard with flashlights at night, spending whole days cooped up in bed reading comic books and fairytales together, and decorating the Christmas tree every year. As Helen's mind wandered, she realised how hot the van was starting to get, the midsummer sun beating down hard. Even with the air conditioning cranked up as high as it would go, she still felt her pits starting to get a little damp, a similar situation happening in her pants. 

After a few hours of driving, the urban landscape slowly transitioning into deep woods, the van came to a stop in front of a large cabin, the building owned by one of Helen's close friends. Everyone got out to stretch their legs and ogle at the wonderful sights, birch trees surrounding the cabin on all sides, a few small hiking trails starting from the edge of the yard and snaking around. As Monroe was reaching for his suitcase, one of the canines stopped him, smiling as the dog grabbed it instead,
"Oh don't worry about it boy, I'll get everything unloaded out of the van. You and your mom just go and enjoy your vacation, you've both earned it!" 
Thanking the man, the rat joined his mother, Helen gently stretching her arms in the shade,
"Got nothing better to do than hounding your mother, huh? Not gonna say hi to those girls?" 
She giggled as his cheeks flushed lightly, the boy shrugging, 
"Ehh… maybe a bit later on…" 
"Well if you're not gonna enjoy the company, I'll have to just make you enjoy the scenery I suppose. How about you come along with me for a little hike? Was thinking I'd head out to the small river towards the east."
"Sure, that sounds nice, would be good to walk a little after sitting still for so long." 
"Good, c'mon then." 
The duo headed out, Helen choosing one of the small paths twisting around the forest, Monroe following a few steps behind her. It wasn't long before both rodents really started to feel the summer heat, sweat pouring down their faces and their backs completely soaked even in the shade of the trees. Even still, they both soldered onwards, Helen completely lost in the delight of the forest. Monroe found himself very much spellbound as well, though his eyes were focused on another sight entirely. He couldn't help but to keep his gaze glued on the backside of his mother, her flank bouncing along with each step she took, the fabric of her sweatpants clinging to her round cheeks. He could usually control his fantasies about her, but the prolonged dry spell had turned his mind upside-down, the young man unable to keep her out of his brain. He desperately tried to make his erection as inconspicuous as possible, but even still his shorts started to get very uncomfortable. He lagged a little bit behind Helen to make sure she wouldn't glance at the bulge on his crotch, though that only forced him to stare at her ass even more, worsening the situation. Eventually the pair finally made it to the river, Monroe quickly sitting down and hunching over to hide his erection. 

After a few moments of relaxing by the rushing river, enjoying the bubbling sounds and the peace, Helen grunted quietly as she staggered up onto her feet, nodding towards the trail leading to the cabin, 
"Alright, I think we've probably done enough sightseeing for one day, better head back before all of the good bedrooms are taken and we're stuck sleeping on the floor, my back can't handle that."
With a smirk, she turned and started slowly sauntering down the path, Monroe getting up and dusting off his pants to follow behind. That meant even more moon gazing for the boy, his throat feeling dry and his heart beating quick as his eyes constantly darted to her ass. After a few minutes of awkwardly trying to tuck his boner away while hiking, the two made it back to the cabin, a few of the other people hanging around outside while the rest were inside, preparing bedrooms and cooking up dinner. Helen stopped to take a breath, wiping away sweat from her brow before turning to her son, Monroe just barely quick enough to lean on the hood of the van, hiding his lower half from her view. He tried not to blush or look too suspicious as she smiled warmly, 
"Thanks for that Monroe, we really need to do this sort of thing more often. We don't spend nearly as much time together as we used to when you were younger."
"Mm… mhm… yeah. Definitely need to spend some more time together!"
She took a moment to glance down at her clothes, lifting up one of her arms and sniffing her armpit before chuckling, 
"Well, I think I've already ruined one set of clothes, thank fuck I packed enough to last the whole week. I really hope they're not hogging up the shower, 'cause I need to get changed immediately…" 
Helen walked off, stepping inside and leaving the boy standing all alone in the middle of the yard, his shorts still only barely containing his package. He sighed as he gently grabbed it, very bad ideas rushing into his mind as he watched his mom's flank disappearing into the cabin, formulating plans that he'd normally immediately discard as the horrible and risky plans they were. But his current state of mind was anything but normal, his dick throbbing as a hint of her sweaty scent lingered in the air for just a fleeting moment.

Helen climbed up the stairs to the bedroom she had been given, her bags already hauled up there ahead of time. She pushed the door closed with one of her feet as she started digging through her suitcase, not realising that the door didn't quite close all the way, left slightly cracked open. She grabbed a new set of clothes from her bag, laying them out on the bed in preparation as she huffed, still slightly overheated. The rat yanked her t-shirt off, her sizeable tits flopping out, her nipples gently showing through the fabric of the bra, perked up in the cool and air conditioned indoors. Her grey fur was wet with sweat, the small room quickly starting to saturate with the potent smell of it, Helen smirking to herself as she wafted her hands in front of her muzzle, opening up a window to try and air the bedroom out somewhat. After her shirt, the next thing to come off was her sweatpants, followed closely by her black bra and panties, leaving the rodent completely nude, standing in the middle of the room. She took a moment to just enjoy the moment, the air washing over her body, her eyes closed as she sighed and leaned against a wall. Her legs were spread, letting her nethers cool off as well, a slight flash of pink hidden beneath thick pubic fur. Suddenly Helen snapped her eyes open, scanning the room, a feeling of being watched running through her spine. Finding nothing out of the ordinary, she just laughed it off, going over to her suitcase and grabbing a towel from it, wrapping it around her body and walking out of the bedroom, heading towards the shower. Unbeknownst to her, Monroe was hiding just behind the corner, only a few steps away from the door to her room, holding his breath as he watched his mom slowly move away. He'd been spying on her for almost the whole time she had been undressing, one of his hands stuffed down the front of his shorts, his fist slowly pumping his dick, wetting his boxers with his precum. The private show had been a wonderful bonus, but he had yet to acquire the main prize he was after. 

With a swift and silent step, Monroe creeped into Helen's bedroom, the door quietly creaking as he inched it open. Peeking into the hallway for one last time to make sure there weren't any witnesses, he slipped into the room, his eyes completely focused on one thing and one thing only: his mother's well-worn panties. The clothes she had just taken off were all in one big heap on a chair, and she'd definitely just stuff the whole lot into the laundry without giving them a second look as soon as she got back from the shower, so surely she'd be none the wiser if he took the pair for just a few moments to have some fun. He could feel his throat getting dry as he carefully grabbed the panties, holding them up with both hands. He audibly moaned as he stuck his nose directly into the back of the pair, sniffing in Helen's musk until his head spun, his dick as hard as steel. Gathering himself, Monroe stuffed them into his back pocket and slowly sneaked out of the bedroom, making his way to a place where he could properly enjoy his spoils without any risk of being found and interrupted. He jogged into the upstairs toilet, frantically closing the door behind him and locking it, his heart galloping like a racehorse as he yanked the panties from his shorts, laying them out on top of the closed toilet lid before pulling down his pants and boxers. His cock had a constant drip of pre flowing from its tip as he knelt down in front of the black panties, rubbing his face into them as he jerked off, sniffing the dirty underwear with his eyes closed. The boy gasped and moaned, mumbling under his breath as he milked his shaft, imagining Helen sitting on the toilet with her thighs spread wide open and his head buried between them, 
"Ohh yeah… you like that mom? You like your own son eating you out? I'm gonna cum in you, I'm gonna fill your pussy!" 
Dragging his tongue up and down the fabric, the rat was close to his breaking point, his pent up energy needing to erupt. He aimed his tip at the panties, his hand sliding up and down his cock the whole time, as he gasped for air and groaned, thick ropes of cum flying through the air and splattering all over the toilet and the pair of underwear, 
"Fuck… take it, take it all! I'll fuck you until you can't stand up, creampie your cunt and watch it all trickle down your legs!" 
His hips bucked against his fist as he came, sperm soaking into the black panties until it was almost completely covered in white streaks, his shirt stuck to his back from the sweat as he panted. Monroe simply sat completely still for a few moments, his head hazy with pleasure and lust, his lungs screaming for air. Finally he started to regain his consciousness, shakily getting back up onto his feet, his whole body trembling from the force of his orgasm. He grinned as he looked down at the sight he had caused, slowly licking his hand clean of his cum as he pulled his shorts up. He decided to leave the mess on the panties, the idea of his mother unintentionally handling her underwear completely painted with his seed making him half chubbed again. To his joy, his mom was still away in the shower, leaving him ample time to sneak back into her room, making sure the way was nice and clear beforehand. Before he stuffed the underwear back into the pile of clothes, Monroe gave them one last quick little kiss, sighing happily while he staggered away, one big load drained from his balls. Though even afterwards, he was still quite pent up, smiling to himself as he thought about going for another round of panty raiding at night once he'd get horny again. 

Helen strolled to the shower room, her bedroom unfortunately situated entirely in the opposite side of the cabin to the shower, forcing her to walk all about with a towel wrapped around her curvy body. When she finally managed to get to the shower room, to her chagrin it was already in use, multiple people calling for their turns afterwards, everyone wanting to wash away the effects of the sweaty car ride to the cabin. Quietly grumbling to herself, the rat turned around to start heading back to her bedroom, only to be ambushed by one of her friends, getting stuck in a conversation for a while. It was only a handful of minutes later that she managed to drag herself away from the little chat, quickly scampering to her room, closing the door and dropping her towel. Helen grabbed the set of new clothes she had laid out on the bed, tossing them back into her suitcase. Since the showers would be completely hogged until later in the evening, there wouldn't be much point in ruining clean clothes by instantly tarnishing them with her sweaty body, her old outfit would have to do until she could get some time in the shower room. She sighed and absentmindedly reached over to the pile of discarded clothing on the chair, grabbing her panties. Instantly her eyes widened in confusion, feeling an odd sliminess that certainly wasn't there before. She lifted the pair up to her face, huge globs and pools of cum staining the black cloth of the underwear, the unmistakable musky scent of seed woven into the sweaty smell. It didn't take long for the woman to connect the dots as to what had happened: the number of males staying in the cabin was already quite low, and the amount of those males who would be perverted and desperate enough to wank off on her sweaty panties narrowed it right down to just one convincing possibility. Helen felt slightly flustered for a moment, a mixture of embarrassment, excitement, hesitation, and lust overwhelming her as she thought about her own son playing with her dirty underwear. After a few moments of deliberation, her mind was set, a devious grin forming on her face as she slipped the panties on, gently rubbing the cum soaked front of them against her pussy as she let out a tiny moan. 

As the evening shadows started creeping over the forest, most of the cabin's inhabitants were gathered in the large living room, watching a movie or generally chatting amongst themselves. Monroe broke off from the pack and quietly slipped into the kitchen, getting a tall glass of water and gulping it down, sighing in satisfaction before turning around to head back into the living room. To his surprise, Helen was standing in the doorway, smiling as she silently watched him. He jumped slightly from her sudden appearance, the mother giggling as she spoke in a hushed tone, making sure that the others wouldn't hear her, 
"Sorry about that cutie, did I startle you?" 
"Hah, slightly, yeah. Why're you sneaking up to me like that? And since when did you start calling me cutie again? I don't think I've heard that one since I was still sleeping in a crib."
Helen stepped closer to him, her smile and her stare taking on some more sensual notes, a slight erotic sway in her walk as she cornered him, the young man backing up against a wall, gulping and chuckling nervously, 
"Uhh… mom? What are yo…" 
Cutting him off, she ran one of her hands down his chest, slipping it under his shirt and ruffling his soft chest fur, his breath and his words getting caught in his throat as he desperately tried to speak, or even think remotely straight. Leaning even closer towards him, Helen almost whispered, 
"I noticed the little gift you had left me~" 
Monroe looked at her questioningly before she punctuated her words, his eyes widening and his maw hanging open in part horror and part amazement as she pushed a thumb down the front of her sweatpants, pulling the band of the pants and her panties forwards to give her boy a view of her uncovered crotch, the inside of her black panties and her pussy lips smeared with his cum. She continued, a devious look in her eyes as her gaze pierced his skull, 
"So, did you intentionally leave the panties for me to find in the hopes that I'd return the favour, or did you think I wouldn't notice?" 
"I… I didn't… I was…" 
"Well, either way, you're gonna have your dreams come true~"
Just as she finished her sentence, two of the other people staying in the cabin walked into the kitchen, busy chatting with each other. Helen spun around and leaned on the counter next to Monroe, acting as if nothing was out of the ordinary, just giving the two a quick nod and a smile before turning her head back towards her son. As soon as the people walking in on the intimate moment weren't paying attention, she winked and gave the rat's bulging crotch a quick squeeze, whispering into his ear,
"But not here, we'll need some privacy, meet me outside in a few minutes." 
With that, Helen walked off, leaving Monroe awkwardly standing all alone, a blush on his cheeks and a raging hard on in his pants.

The rat boy anxiously paced around the hallway, constantly checking his phone until about ten minutes had passed, quickly slipping outside through the backdoor after making sure that no one was around to question what he was doing. Monroe walked to the front of the cabin, scanning the yard for his mother, squinting in the dark as the last few rays of the sun were rapidly disappearing. After a few seconds, he noticed the stocky silhouette of her standing next to the van, waving for him to come over. Helen twirled a set of keys around her finger, grinning as she opened the back of the van, clambering inside. He followed suit, hopping in before closing the doors and flicking on a dim light on the ceiling. Both of the rodents were on their knees in the slightly cramped space, Helen shuffling forwards and pulling off her shirt, a big smile on her face as she looked at her unsure son, 
"C'mon, no need to be shy now, it's a bit too late for that~" 
She grabbed both of his hands and set them on her tits, giggling as he blushed, Monroe taking a deep breath before allowing himself to relax slightly, his fingers carefully caressing and squeezing her soft and full breasts. Reaching back, Helen unhooked her bra, letting him get a proper handful of her chest, moaning as he massaged her,
"Ohh… I've missed this so much… Wasn't expecting my own son to be my next lay, but I definitely could've done a whole lot worse~" 
Both rodents laughed as she started slowly shimmying her pants down, prompting Monroe to begin undressing as well, the two of them soon staring at each other's naked bodies. Her pussy was hidden behind a puffy pubic bush, her juices slowly trickling down from her slit as she huffed. Helen grabbed her son in a deep embrace, kissing him, his dick grinding against her belly, leaving spots of precum to stain her fur. Without much warning, she suddenly pushed him down on his back, sliding her crotch over to his face. His yelps of surprise were quickly muffled and drowned out by the mother's moans as his muzzle pushed between her thighs,
"I hope you don't mind the sweat~" 
Monroe's nose burned with the intense musk, his lungs filling with his mom's aroma, his cock throbbing and squirting ropes of pre with every inhale. Opening his muzzle wide, he let his tongue lap at her pubes and cunt, relishing the smell, the taste, and the sound as he ate her out. Losing herself in the moment and the lust, Helen grabbed the boy's auburn hair with both hands and started riding his muzzle, grinding her pussy down against it, making sure his tongue was reaching as deep into her as possible, caressing her every inner fold as her honey dripped down his chin. She gasped and howled in pleasure, muttering encouragement whenever she was able to string together a few coherent words, 
"Mmh… fuck… keep going, don't stop! Eat your mommy out, lick me good and deep, good boy!" 
As suddenly as she had planted her pussy on his face, Helen lifted herself up slightly, only to shift forwards and thrust his muzzle directly between her sweaty asscheeks, his nose prodding at her tailhole. Eager to please her in any way possible, Monroe rimmed her as deep as he could, her hole puckering around his tongue as she almost screamed, her thick ass and thighs holding him firmly in place. 

The young rat man continued to eat Helen's tailhole out for a few moments, her moans and yelps egging him on. Without warning, she pulled herself off of his face, panting hard as she first glanced down at him, and then his dick, pure lust on her face as she slowly moved down, hovering her nethers right above his tip. Monroe gasped for air and yelled in panic, 
"W...wait, don't! I don't have a rubber on me, I left my condoms in my room, we can't…"
She grinded her lips up and down his shaft, smearing her juices all over it as she moaned, one hand on his chest to steady her and one hand grabbing his dick, 
"Don't you worry about condoms sweetie, I'm not going anywhere until you blow a load in my womb~" 
"Wh… what!?" 
"You're gonna give me another son, right here and now~" 
Helen pushed his tip between her lips, Monroe groaning and throwing his head back as the feeling overwhelmed him, his mother's pussy slowly swallowing his shaft inch by inch,
"Oh… shit…"
"Good boy, fuck your mother, cum in me!" 
Happily following her orders, he started bucking his hips up against her, thrusting his cock into her hungry pussy as she rode him, the whole van gently rocking back and forth as the windows fogged up. Helen could barely sit up straight, her toes curling up and her pink tail wrapping around one of his legs as she whined and moaned, his pubes quickly soaked in her strong smelling essence. Monroe held her hips tight as he fucked her, his length squeezed and milked by her tight passage. He huffed as his squirts of precum had turned into an almost constant flow, his balls aching for release, 
"Mom, I can't hold it much longer, I'm gonna…" 
"Do it, fill me up and breed me! I want your seed in my cunt!" 
Letting out a long groan, Monroe's cock erupted like a volcano, buried deep in his mother's pussy. In just a few shots, her womb was completely coated in the boy's potent sperm, trickles of the thick seed escaping from her lips as she moaned in ecstasy, the feeling of his hot load stuffing her full pushing her over the finish line, her walls tightening as a pool of her juices soaked into his crotch and belly. 

Helen pulled herself off of her kid's shaft, flopping down on the floor next to Monroe, cuddling up to him as her creampied cunt overflowed with young and strong seed, her thick pubes coated in the creamy liquid. The whole van stunk like a whore house, a strong smell of breeding and perspiration permeating throughout it. She pulled him close to her, the boy wrapping a hand around the back of her head and kissing her, Helen moaning as she grabbed one of his hands and brought it to her belly. Smiling warmly, she cooed to Monroe, 
"You're gonna feel your baby kicking in here soon enough."
"How do you know that you're knocked up?" 
"Well, your dad's seed was potent enough that just a small spill from a slipped condom was enough. Based on your size, I'd say you take after your daddy in a lot of ways. But you never know for sure, might be good to play it safe and repeat this a few times, huh?"
Both rats laughed as Monroe slowly stroked his already hardening dick, 
"I think I'd be alright with that." 
As the sun completely disappeared behind the thick forest, the van started rocking back and forth once more, a muffled moaning carrying out from it.
