#5 of Writing Commissions

Toriel wakes up one morning to find herself fully, painfully erect for the first time in nearly twenty years... As she hesitantly strokes her sizable shaft to climax, hoping to deal with her excessive erection, she quickly finds that it's only making matters worse as a few decades' worth of pent-up sexual energy surges into her prodigious package with every orgasm she has! Her cock only grows larger and larger and soon enough she's uncontrollably pumping untold gallons of boss monster ball batter out into the Ruins with reckless abandon!

A great comm done for Chip_At_Night on twitter. Chip and I share a mutual ludicrous lust for some big goatmom so this was a real fun one to write.

"Mmmmfff... Oh goodness, w-what time is it?"

Toriel sat up in her bed, propping herself up against the ornate wooden headboard and rubbing her eyes. The room was completely dark and silent, and even without looking at the clock on the bedside table, the tall goat woman knew that it was far too early to be up. Glancing towards the window, the inky blackness of the ruins outside confirmed her suspicions. Not even the distant ribbits of Froggits could be heard, every monster around fast asleep but her.

She reached a soft furry paw over to the lamp on the table, clicking it on and bathing the room in a dim orange light. Squinting from the sudden illumination, her eyes slowly adjusted, trying to find whatever may have caused her to wake so early...

"Oh my-" Her question was answered as her eyes fell upon the silky purple blanket, a tall, pointed tent poking up from around the center of the bed. Throwing the sheets off of her body, Toriel blushed a deep red as the pinkish, fleshy shaft of her cock flopped heavily from beneath the covers. Standing at about six inches long, it was fully erect, gently swaying back and forth...

While her cock itself wasn't a surprise- she had had it for all her life- the raging erection certainly was one. "N-nngh, oooh..." She couldn't help but eke out a tiny, high-pitched moan as it let out a hefty pulse of need. She couldn't remember when she'd been this painfully hard before, much less when she'd been hard at all. It must have been decades, no, centuries since she had last even thought of jerking off, she could hardly bear the thought of doing such a lewd, explicit thing...

Sitting in silence and staring down her sizable shaft, Toriel tried to think. Extending her other hand, she gently poked at the erection, feeling nothing but a tiny twinge flow through her loins... Her head swirling, she found a strong urge to touch it more tugging at her thoughts... Maybe just one time wouldn't hurt, it had been so long and she needed to get back to sleep...

"A-aaah! Ooooh, oh goodness..." Wrapping her hand around the girth of her cock, she gripped it gently, bringing her arm slowly upwards and downwards as she caressed the pulsing, vein-covered mass with cautious enthusiasm. God, she thought, it felt so good... The warmth spreading through her body with each motion was unlike anything she'd ever felt before, a euphoric tingle rushing from the point of contact down her shaft and out to every inch of her arms, legs, and head as she found herself moaning and panting lewdly... She swore that with each stroke she could feel it throbbing larger and larger, its cute pink tip poking out from her hand as she kept going, faster and faster...

Unnoticed by the horny goatmom, her cock actually had grown larger, the sudden stimulation after decades of abstinence sending it into overdrive as her enormous erection swelled from a modest six inches to a huge eight inches. Its length was hardly the biggest concern for Toriel, though, as she felt a sudden surge of lust washing over her body, her back curling, her legs spreading wide, and her balls clenching tightly as she experienced the first orgasm she'd had in ages...

"A-AAH! H-hnnngh, h-holy..." Stopping herself before she said anything improper, she squeezed her eyes shut, hands shaking as the belly of her cock bulged with the load shooting through it. Her shaft, angled upwards, erupted in a fountain of goat "milk", a fat, thick rope of off-white cum flying gracefully into the air and landing with a soft splat directly onto her fluffy fur. It refused to stop there, though, her balls forcing out as much as they could offer as she instinctively pumped her cock, coaxing out each new spurt of sticky spunk... It caked onto her face and bare breasts, sending jiggles through the soft, bountiful breastflesh as it practically covered every inch of her pure-white fur. She couldn't care less in the moment, though, abandoning her typical composure as her soft, half-subdued moans and squeaks of orgasmic bliss shattered the early-morning silence of her home...

"G-good heavens, t-that was... so much~" Sweating bullets and covered head to chest in dense, creamy goat cum, Toriel looked down at her cock. Her intense orgasm had finally tapered off, and her shaft had seemingly softened back to a modest size, the warmth from before subsiding a little bit as she let out a sigh of relief. "T-that's better..."

Ribbit...

"Oh m-my, morning already?" Her moment of breathless awe was broken as the soft sounds of the other monsters waking up outside told her that it was finally sunup. A small, dim ray of sunlight shone through the roof of the Ruins, filtered by the dense canopy of leaves and hitting the carpeted floor of the goatmom's bedroom...

She got carefully to her feet, shooting the occasional glance down at her cock as she wiped some of her... emissions off of her face. It was still soft, eliciting a satisfied smile from the boss monster as she pulled open her wardrobe drawer. Drawing out a long, flowing purple robe with a small flourish, she slipped it onto her still-wet fur. Everything from her breasts up was completely drenched, and there was no way she'd be able to get her daily chores done with her body in such a lewd state... She'd have to clean it off in the bathroom.

Her paws making soft, muffled footfalls on the cool tile floor of the bathroom, Toriel made her way over to the sink, letting out a deep sigh. One turn of the knob and the water flowed forth with a soft FWSSSH, her gaze shifting upwards and staring into the aged mirror...

The Toriel looking back at her flushed deeply, her face shifting with a mix of embarrassment and arousal as she stared in awe at the countless ropes of cum crisscrossing her features. She should have felt ashamed that she'd let herself get so... so depraved, but something deep inside her fought against those feelings, and they were replaced instead by a jolt of excitement...

THUMP!

"O-oh my, not again..." Her head snapped downwards, flinging a few drops of sticky spunk into the sink as her eyes fell upon a massive, wet bulge in the front of her dress. She watched in awe as her cock grew visibly more erect, having smacked against the cabinet door of the sink and left a sticky coating of precum behind.

She couldn't help herself, and before she could think, a hand reached down from her side and pressed firmly against the turgid bulge. In an instant, she was slammed with a shockwave of arousal, her body almost doubling over from the sudden rush of pleasure as her cock pumped out a huge glob of steaming precum. "Oh g-god, y-yes... I-I need m-more!" She fell against the wall to her side, using her right arm to brace her body against it as her left hand set to work furiously stroking her cock once more. She didn't even take the time to remove her robe, gripping the slicked shaft through the prespunk-saturated fabric.

It felt so good, her mouth lolling open from sheer, undiluted lust as she panted like a dog. Each and every tiny motion of her hand caused her enormous endowment to gush precum like a broken faucet, her dress soaking up most of it as it darkened with moisture and sagged heavily to the ground. Once it could take no more, her sloppy spurts passed right through it, arcing through the air and falling into the sink with a series of wet splats. The running water ensured that most of it was sent down the drain, but at least half ended up dripping thickly down the wooden surface of the sink cabinet, pooling on the porcelain floor below.

Toriel couldn't see it underneath her dress, nor would she have likely noticed through the dense haze of lust clouding her thoughts, but her cock had surged in size again, gaining an additional four inches of length as it finally hit the one-foot mark. Her shaft was far from all that was growing, though, something that became more than clear as a deep, thick gurgle reverberated off of the bathroom walls. Swinging heavily underneath her robe, her round, fuzzy nuts had swollen to the size of basketballs, brewing up several centuries' worth of long-overdue orgasms all at once and depositing them directly into the dense, churning cumtanks of the monster matriarch.

Toriel barely even saw her next orgasm coming, practically screaming out with lust as she finally came. "H-haaaaah, mmmmmf..." Her robe was much too far gone to do anything to stop it as a torrential flood of fat, steaming ball batter blasted into the air and hit the mirror squarely in the center before splattering back down into the sink. The sheer volume of her load managed to overtake the flow of water and the capacity of the drain, filling up the bowl of the sink in a few seconds flat and overflowing, surging down the sides of the cabinet in great big rivulets and creating a rapidly-growing pool of the stuff on the bathroom floor. Tori could barely think let alone do anything to stop it as her balls just continued to fill up nonstop, every gallon she pumped out replaced almost immediately by two more.

She lost track of time, her shaking arm giving way and falling from the wall as she landed with a splat in a four-inch-deep layer of accumulated cum. The mirror and windows were fully fogged up by the steady steam rising from the perverted pool, and the goatmom's previously-purple robe was now completely white.

"H-hohhhh, good gosh, that w-was amazing~" She lay there for a few minutes straight, breathing heavily and still stroking her shaft even as it ran dry, feeling it soften ever so slightly back down to its normal size. A strange sense of pride washed over her as she scanned the ruined bathroom, palming her watermelon-sized orbs through her dress with one paw and feeling her ears twitch as they let out a low rumble. This was going to be impossible to clean up, but by this point, she had to finally be relieved enough to go about the day normally. She probed around the spunk-splattered room to find something to brace herself on and picked herself up, shaking off her head a little bit before walking back out into her bedroom...

"A-alright, Toriel, keep it- nngh- together," she mumbled to herself, stifling moans as her mind swirled with the lewd, alluring image of her flooding the bathroom. Some baking was bound to take her mind off the huge, wonderful, amazing feeling of drenching everything in her c-

Shaking her head to clear her thoughts, she stepped into the kitchen, putting her hands to her damp hips as she tried to remember how she usually went about making a pie... It seemed so much harder to recall this morning, and she couldn't seem to put her finger on it.

Straightening up with a small "Aah!" she remembered her recipe book, out in the dining room. Turning around in the doorway, she made her way over to the kitchen table, flipping open the aged, yellowed tome sitting on top of it.

Snail and eggs, snail sausage, creamy snail soup... she pawed through the length of the book, trying to find what she was looking for, but quickly found herself becoming impatient. The all-too-familiar heat beginning to build down below was certainly not helping matters, and she felt her legs involuntarily spread apart as her prodigious package pulsed once again with growth...

Throwing the cookbook to the other end of the table, Toriel steadied herself on its surface, reaching down below and grabbing hold of her cock for the third time that morning. "J-just a little more, g-gotta get it all- nngh- out~" She gasped between her moans as she found herself unable to wrap her paw around the full girth of her shaft, looking down to see that her endowment had enlarged to just over two feet long. Her robe was only just barely containing it, stretching obscenely and threatening to fail as it hugged every inch of her shaft almost skintight. Below, her balls were nearly twice the size they had been in the bathroom, and even just looking at them sent a burst of lust through Toriel's body that caused them to pack on another few inches of diameter. They felt so full and pent up, the pressure within almost driving the rutting goatmom mad as the sticky schlicks of her frenzied fapping filled the entire house with a symphony of lewd sounds.

She couldn't take it anymore, using the hand that was bracing herself against the table to grip tightly onto her robe and tear it off with a resounding RRRRRRRIP! Out from beneath the ruined fabric flopped her fat pair of tits, two enormous, white-furred, wobbling masses each tipped with a puffy, donut-sized pink nipple that dripped milk like a garden hose. Her intense arousal had clearly rubbed off on parts of her body besides just her cock, sending her mountainous milktanks into overdrive as they sloshed with just as much capacity and production as her balls.

But the part of her body she was most interested in was her cock, any and all embarrassment she may have once had thrown to the wayside as she proudly admired her drooling, bouncing bitchbreaker as it flopped heavily onto the table, immediately forming a pool of steaming precum a foot wide. It was bigger than anything she'd ever seen before, over two feet of pure, concentrated virility swinging from her waist and begging for release. "G-gods, yes~ I need to grow b-bigger..."

Without delay, she took both hands this time, clasping each over half of her cock's diameter and beginning to stroke herself off madly, accompanying her lust-drunk motions with thrusts of her hips that made the barrels of ball batter below churn and slosh with their untold gallons of potent goatmom seed. The flow of precum passing from her turgid tip was now comparable to her earlier ejaculation in the bathroom, putting most normal orgasms to shame as it arced into the kitchen, landing squarely in the dish-sink at least four meters away and filling it up with the sticky, steaming fluid.

By the time she had approached her limit, feeling her balls clench tightly, every inch of the kitchen was already caked in a thick layer of fresh goat precum, and a deep pool of the stuff was slowly creeping its way out into the dining room. As if that wasn't enough, though, she finally came for real, mind jumping in and out of consciousness as the belly of her beast of a cock bulged obscenely with a mud-thick blast of cum easily as wide as her arm. With a thunderous GLORP that drowned out every last one of her high-pitched, orgasmic moans, it hit the kitchen sink and practically exploded, drenching the ceiling, walls, and everything in between with a relentless onslaught of hot, sticky goat cum. Her climax lasted twice as long as last time, and was easily five times as intense, Toriel's field of vision little more than an undulating mass of cum as the kitchen was completely and utterly flooded.

Eventually, after what seemed like hours her endless, body-convulsing, ball-draining orgasm, her cock stopped pumping enough for Toriel to regain her composure, slumping back into the wooden chair behind her as her cock spurted one final, dense blast of cum that covered what little dry space was left on the kitchen table. She was huffing and puffing after the whole ordeal like she had just run a marathon, but nonetheless found herself feeling just as energetic as ever, getting shakily to her feet as she walked over to the kitchen door to check on the damage.

Her cock swinging back and forth in front of her and her massive cumtanks churning softly with each footstep, she examined the kitchen. It looked as though an enormous, sticky, steamy snowstorm had hit the room, the general forms of each cabinet or appliance barely visible underneath a six-inch-deep layer of thick, virile boss monster batter as her head swirled from the scene alone, much less the pheromones billowing off of it all. The floor had been converted into an impromptu jacuzzi of jizz, half a foot of the stuff coating every inch and undulating like a river.

"O-oh dear... M-maybe I should go outside if I'm going to be doing this..."

As much as she knew how difficult it would be to clean this morning's messes up, Toriel could hardly bring herself to care, her mind having long since shifted to focus exclusively on her incredible cock and seeing just how far she could go with it. Still, though, she needed to get something done today, and hopefully a more open space out in the Ruins would provide her ample opportunity to unload...

The next few hours of her day continued, as to be expected, very much similarly to the first few. Not bothering to put on another robe, the gloriously hung goatmom walked outside into the sunlit Ruins, leaving a steady stream of mixed precum and goatmilk behind her as she walked. Just about all of the smaller monsters inhabiting the ancient halls turned to gaze at her quizzically as she passed, usually hearing the thunderous sloshes of her milk-filled mammaries and the cacophonous churns of her oversized cumtanks far before they ever caught sight of her.

Despite her best efforts to accomplish her daily duties around the Ruins, she found herself constantly distracted by her enormous erection. Bending down to water a patch of flowers and unintentionally spurting a couple gallons of goatmilk onto them, the tip of her hypersensitive cock rubbed against their leaves, sending such a shock of arousal through her loins that a blast of ball batter burst forth in an instant, completely flooding the room and ruining the flowers as she found herself unable to stop the endless flow of sticky seed. With each and every orgasm she experienced, her package surged larger and larger, her cock lengthening to two-and-a-half feet and her nuts ballooning outward to the size of beachballs...

Next up, she walked to the end of the Ruins on her daily check for any fallen humans. Alas, her balls had now reached such a size that they constantly rubbed against the floor, actively causing the loose brick tiles on the ancient floors to vibrate as they brewed up a few fresh loads of goat nut. The thin, soft blades of grass in the Ruins' entry room proved to be too much for Tori to bear, the sensation of a thousand tiny fingers caressing her overstuffed orbs forcing out another few dozen gallons of her thick, creamy devastation. Now a full three feet long, her balls had reached the size of armchairs, wobbling and bouncing behind her as their deep sloshing drowned out all other sounds... Joining in on the symphony of sexual sounds were her breasts, whose milk output had shifted from constant flow to what could only be described as an endless gushing as thigh-thick streams of pure-white goat milk hosed down anything and everything in front of her. She found it increasingly difficult to focus as her ample assets got louder and louder...

Finally, she found herself back at the entrance to her house, standing before the enormous, blackened tree in the courtyard of the Ruins. She always made sure the tree was in impeccable condition, and, as usual, scanned it for anything out of place. Eyes falling upon a stray leaf nestled between some of its upper branches, she reached up to grab it...

Unintentionally, she squished her breasts together, angling both of their nipples downward as the blasts of milk found themselves converging directly on top of her throbbing, meter-long monster meat. "O-oooh, n-nngh, gods-" Feeling her entire shaft getting drenched with warm, creamy milk was the last straw for the hugely hung goat, and she fell back onto her bountiful butt, moaning lewdly as both her cock and her breasts experienced their largest climax of the day. The deafening glorp of her balls unloading as much of their contents as they possibly could was audible from just about anywhere in the Ruins as a geyser of cum nearly six inches thick shot from her tip, splattering against the roof of the ancient courtyard and raining down onto both the lust-drunk goat and the rest of the room in massive, thick droplets. By the time it had finally subsided, the whole place was in a similar flooded state as the rest of the Ruins...

Toriel picked herself back up and gazed around the room with a mix of arousal and awe, admiring the sheer volume she had managed to release. Looking back at her cock, she found that it had gotten larger still, standing high above her head at what looked to be just under four feet long; her balls, impossibly, had also grown, the hundreds of gallons of dense cum she'd just unloaded seemingly making no difference as they were just as productive and just as loud as before. They felt impossibly full and bloated, wobbling and pulsing as though she hadn't cum at all...

A little bit frustrated, her eyes found themselves slowly fixing themselves on her throbbing tip, which was swaying enticingly in front of her. It was gushing precum as though she was cumming, the translucent fluid steaming as it hit the air... It looked so... tasty, she thought.

Schlurp-

Without a second thought, Toriel brought her mouth to the tip of her cock, slipping it just barely inside as she opened wide to accommodate it. Immediately, as though she had flipped some kind of switch, her body was slammed by a tsunami of pleasure unlike anything she'd felt that day, let alone ever- a feeling that completely overtook her mind and sent her thrusting her head downwards, forcing more and more of her cock deep into her throat as the Ruins began to fill with the sounds of her own sloppy selfsuck. It was a feeling of utter bliss, her entire body tightening and convulsing with lust as she shoved inch after inch, foot after foot of the hot, thick cock inside her without a hint of hesitation. Her breathing became heavy but she kept going, lewd, wet glurps and schlurks resonating over the thunderous churns of her bloated, backed-up balls as she dived deeper and deeper onto her bestial endowment.

It didn't take long before she reached as far down as she could go, about two feet of pulsing, needy goat cock crammed into her tight mouth as she squeezed her breasts firmly against whatever length wasn't stuffed inside. Try as she might to force more of it inside with each frenzied, cock-drunk thrust, she couldn't- but she didn't need to.

She felt the all-too familiar sensation of her load building, and even though her ears were still reverberating with the sounds of her sucks, she nonetheless heard the deep, thick rumbling of her balls preparing for release. Managing a few muffled moans of desire through her cockstuffed throat, she pulled back one last time before surging forth and slamming her shaft into her stomach, with perfect timing as her head spun with the orgasmic bliss of her climax.

SPLORT!

She barely felt her cock bulge to nearly twice its width over the sensation of her belly bloating obscenely, feeling her own thick, warm cum flooding every inch of her insides and stretching her out to her limit as she dutifully kept her shaft stuffed tightly down her throat. As much as she would have wanted to just keep it there for hours, relentlessly filling herself until she could barely move, her belly ten times her size, it wasn't meant to be- It took barely a few pumps of her cock before her stomach reached its capacity, ballooning to the size of a large yoga ball before the pressure of her cumflated belly forced her cock from her mouth. Her load was far from over, though; the pure pleasure of her forceful facefuck had finally been enough to satiate her shaft as it further flooded the front of her house, her balls receding in size at last as they no longer produced faster than she could unload. Falling back into the rapidly growing pool of cum from exhaustion, she found that it was so deep that her entire head was submerged with a soft bloop.

Sputtering a little, she sat back up, bracing herself against the brick floor and taking a deep breath as her cock fired off the last few voluminous volleys of dense goat cum. She could barely see it behind her cumflated belly and bloated breasts, but she felt it finally soften for real, letting out a deep sigh of relief as she patted her stomach contentedly. "Mmmmmff, tomorrow is sure to be just as arousing~"
