She suddenly found herself wide awake, snapped out of a deep sleep in seconds. There was no gradual waking or grogginess; she simply went from complete unconsciousness to fully alert. The remnants of the dream she'd been having were fresh in her mind, to the point they felt almost tangible.
It was a bright white room, but she couldn't make out where any walls or floors started or ended. She caught glimpses of tall, humanoid creatures surrounding her, and remembered feeling as if she were being examined, poked, and prodded.
Now, she was back where she belonged, tucked into her bed. As she began to pull herself more upright, she felt a strange sensation in the pit of her stomach, and a soreness in her breasts. Her hands glided up to them, making herself wince as she felt them. It must be her period, she thought at first, but didn't she just finish it last week?
The feeling in her stomach slowly became more pronounced, and she noticed a growing pressure. Looking down and holding her hand just below her belly button, she gasped, feeling the skin slowly stretch and push out. For several moments, she stared down, gasping as she held her belly and watched it swell. It was already beginning to protrude significantly, and she watched on in horror as it began to poke out from beneath the small tank top she wore. In under a minute, she went from having a completely flat belly, to looking as if she were three or four months pregnant.
A panicked groan escaped her lips as she looked around frantically. She didn't know what she was looking for, just that she needed help, and to make whatever this was stop. Her phone was no where in sight, oddly, but she hardly had the time to look for it further before she felt a new sensation. It felt as if there were something fluttering around inside of her, almost as if it were... kicking. She screamed, holding her growing belly, shock and fear overtaking her as she realized she was pregnant. But how? And with what?
Already, she was beginning to look about five months along, and her belly button was starting to be pressed flat by the mass growing inside of her. Grunting and whimpering, she began to drag herself out of the bed, struggling to balance herself on her feet with the newly added weight in her middle. She looked all around the room, but her phone was no where to be seen. Could she have left it in the bathroom or something?
As she went towards the door, she found herself holding the bottom of her swollen belly with one hand to support the growing weight. The movement was getting stronger and more frequent, and each little jab made her gasp and shriek. Just before the bathroom door, she had a floor length mirror on the wall, and as much as she didn't want to look, she couldn't stop herself.
She let out a shuddering cry as she saw herself, already looking huge and pregnant, complete with a very pregnant stance of cradling her belly with one hand, with the other pressed to the small of her back. Her belly button had started to protrude, and a dark line ran down the middle of her belly just beneath it. As she stood transfixed by the horror of watching herself swell up, she saw the shape of a limb pressing out against the side of her belly, at the same moment her belly button popped out completely. Suddenly, she was very aware of how her breasts had grown, now reaching the point that her tank top was becoming tight around them.
Whimpering, she waddled into the bathroom, frantically searching over the countertop for her phone, but it was no where in sight. It wasn't even on the floor. Groaning in fear and desperation, she hurried out to the living room, finding herself growing heavier with each and every step she took. Looking down, she could no longer see her feet, and realized that she looked to be about full term. "No, no...!" she groaned, huffing as she struggled around her apartment, searching for her phone.
Where could it be? How could she have lost it, and at such a dire time? She made a noise that was halfway between a groan and a sob as she waddled back to her bedroom, thinking she must have missed it somewhere in there. The thing inside of her continued to move, wriggling and squirming beneath the surface of her stretched skin.
Her phone was no where in sight, and she'd searched the entire apartment, at least, as well as she could while lugging around her huge, growing belly. Exhausted, she had to sit down on the bed, leaning back and propping herself on her arms.
Panting, she stared down at her belly as it grew bigger and bigger by the second. She looked like she was very far along with a set of triplets. Her belly felt so full and heavy, and the thing (or things, she presumed) she was carrying wouldn't stop kicking. She was getting huge, and just a minute of holding herself up like this was beginning to take its toll, and so she struggled to pull herself back on top of the bed, huffing and puffing and grunting and groaning from the effort.
Now, leaned back against her headboard, legs spread to make room for her widening girth, all she could do was stare down at her massive, active baby belly as it grew and grew and grew. Instead of becoming more used to the idea, her horror only grew alongside her overstuffed womb. She screamed as she grew larger and larger with every passing second, seeing large lumps form where the creature inside of her kicked and pushed from inside of her.
Her breasts were getting huge, as well, and the shorts she wore were becoming uncomfortably tight, making her realize that her ass must be growing, too. The realization that she would have to give birth very soon made her feel almost ill, but the logical part of her brain that thankfully was still working thought to remove her shorts. It was a struggle to maneuver around with the huge size and weight of her own belly, but she eventually managed to get them down far enough to kick them to the floor.
Leaning her head back and whimpering, all she could do was close her eyes and hold the sides of her swollen mommy belly, hoping and praying that this was all some sort of nightmare.
When she looked back down, she let out a small scream, seeing how huge she'd gotten just in the past few minutes. She looked extremely overdue with sextuplets, at least. As she held her hands against the sides of her impossibly large belly, she felt and saw more kicking and squirming, the shapes forming beneath her skin so large, it finally dawned on her with a cold sinking feeling that there was only one creature growing inside of her. Wailing, she gripped the sides of her growing belly, wanting nothing more than for this to be over.
"Stop...! Make it stop...!" she groaned, rubbing all over her pregnant mass. Whatever was inside of her rolled and kicked against her hands, making her cry out. No matter how much it moved, she couldn't get used to it.
Her tank top had only been covering her breasts for quite a while, and now, only barely. It felt so tight, and she could hear some of the stitching beginning to tear from how huge her breasts were getting. She pulled at the hem and tore more of the stitches, but she wasn't able to tear it enough to get it off. In addition to the soreness she'd been feeling, and how uncomfortably large her breasts were becoming, there was now a pressure growing inside of them. In seconds, they felt unbearably full, and she whimpered at the discomfort of feeling so full all over.
The thing in her belly grew and grew, writhing and twisting around inside of her. It seemed to be moving more than ever now, and she groaned loudly as a painful cramp seized her belly and sent her offspring into a frenzy.
"Ohhh, god...!" she cried as the cramps kept coming, faster and stronger each time. The only relief she felt was a small, brief release of pressure in her breasts, and when she looked down, she saw dark, wet spots forming over her nipples. She was leaking milk. Her body was actually producing milk to feed this thing she was growing inside her womb.
As she sat staring in horror at her lactating breasts, she was interrupted by the most intense contraction yet. She couldn't hold back her scream, and felt as if something popped between her legs, followed by a big splash that completely soaked the bed. "Oh, god, no...!" she whimpered, realizing she was truly going into labor. Something huge and round was forcing its way into her birth canal, and she was going to have to push it out very soon.
Whatever she was giving birth to had to be the size of a fully grown man. How would she ever get something that big out of her and survive without any sort of medical intervention? Unfortunately, there was nothing she could do but follow her instincts, which were telling her to push.
Gritting her teeth and groaning loudly, she bore down hard, until her groans turned to screams. The thing in her belly was kicking, as if it were trying to get the leverage to force its own way out of her. "Hoohoohoohoo...!" she panted, desperately trying to catch her breath after pushing.
As she pushed again, she felt herself being stretched impossibly wide, as if she were being split in two from the inside. But somehow, nothing tore or broke, as far as she could tell, and she just kept pushing. Gasping and panting, she rubbed the sides of her impossibly distended belly, trying to ease some of her discomfort, but to no avail.
Another intense contraction came on, and she screamed as she pushed through it. Even as she sat here, trapped beneath the size and weight of her newly and enormously pregnant belly, birthing an unknown creature, she couldn't wrap her mind around her reality. She was just so very, very pregnant. Desperately, she wanted this to end, and all she could do to make it happen was push.
So she did, with every contraction, she pushed, and pushed, and pushed. Whatever was inside of her was moving down, but just barely. Wailing as she pushed as hard as she could, the discomfort was indescribable as the massive head stretched her birth canal far wider than it should have been able to. She could feel a bulge beginning to form between her legs, which only gave her the slightest bit of comfort, knowing that this was still only the beginning.
It felt like an hour had passed, an hour of nothing but pushing and panting and pushing. Finally, she felt her vagina being stretched wide open as she started to crown. "Ohhhfuck, it's comiiing! It's... I feel the heeaaad...!" she screamed, no amount of time being stuck laboring seeming to help her adjust to what was happening to her. Her breasts had continued to leak, her tank top now soaked, and milk spilling down her sides.
She pushed with everything she had, desperate to get this thing out of her as soon as possible. Wailing, she felt it stretching her wider and wider as the crown grew, forming an absurdly huge bulge. She didn't let up, and finally, with a burst of amniotic fluids, she felt the head pop out from between her legs. Gasping and panting, it was only the smallest bit of comfort, and very short lived, as she realized she now had to push out the shoulders.
The thing turned itself inside of her, and she cried out as she felt it wriggling, struggling to squirm its way out of her birth canal. Another contraction forced her to push, and she felt certain the shoulders would tear her apart as they passed through her cervix. Yet, somehow, she stretched wide enough to accommodate them, though the discomfort was immeasurable.
Shouting and pushing, she continued to labor and struggle to birth the huge shoulders, so big that it shouldn't have been possible for her to fit them in her canal. Her pussy bulged obscenely with them, and she remained stuck like that for some time, barely making any progress with each push.
She couldn't know how much time passed before she gave that big push, the one that finally, finally squeezed the shoulders through her impossibly stretched vagina. Panting, she tried to catch her breath, but found it difficult as the thing making its way out of her writhed around even more inside her, still trying to get itself out from inside her belly. "God...! Stop...! Stop moviiiing...!" she wailed, pushing desperately to try and finally get the thing out of her. She was pulled so wide by it already, she seemed to be making more progress with each push now than before. She could feel it inching out with each push, along with it kicking ceaselessly inside her womb to push itself out.
Suddenly, she felt its arms slide free, and gasped with momentary relief. Her belly was still too big to see anything that was happening past it, but she felt it grab onto the bed and begin pulling itself out. With a shriek, she quickly grabbed the headboard behind her and held tight, unable to stop herself from pushing as it worked its way out from inside of her. Now, she was making fast enough progress that she could actually see her belly slowly deflating as the thing made its way to the outside world.
Screaming and pushing, the hips popped out of her, and she felt the creature pull its legs out. As her belly shrank, a new horror dawned on her as she took in the sight of the thing she'd just spent the day giving birth to.
It was the size of a human man, as she'd suspected it was. It had a humanoid body, but its features were anything but. Its skin was a blueish-green color, and a lumpy, almost scaly texture. Its eyes were big and black, and its ears looked more like fins than anything. She stared at it with wide eyes, gasping and screaming as it rapidly crawled up along the side of her. Her fear left her frozen in place as it grabbed her shirt and lifted it, exposing her huge, leaking teats, not hesitating even for a moment before it latched on and began to suckle, leaving her gasping and staring at it in a state of shock.
After a few seconds, she regained some composure, and began to struggle to free herself from it, trying to pull herself away while pushing on its head. The thing didn't move at all, seemingly unaffected by her efforts, as if it didn't even notice her trying to make it stop.
Forced to stay there nursing this monster she'd just birthed, she silently hoped it would get its fill and then leave forever. Closing her eyes, she noticed there was still some pressure in her belly. Or did it just come back? Shakily, she opened her eyes and slowly looked down. Past the monster she was breastfeeding, she saw her belly, still fairly round and puffy from the birth. She also could see that her entire body had swelled up from the pregnancy, putting on an obvious amount of baby weight all over.
As she stared at her belly, she felt her heart sink into her stomach as she saw that it was growing once again.
Screaming, she held her belly as it swelled up, growing bigger and bigger by the second. She wasn't sure if it was growing at a faster rate than before, but it wasn't long before she was looking full term, to overdue with twins, then ready to pop out a full, huge litter of quads at any second.
The alien growing in her belly - she had determined that was what they had to be - kicked and rolled around just like the one before. The creature suckling from her huge mommy milker had started rubbing her belly as it grew, seeming to enjoy feeling the spots where the one inside would kick. How much did it understand about what was happening? It seemed to know that its sibling, she supposed, was growing inside of her womb. Did it not know how much she hated this? Could it not see that she wanted this all to be over? Or did it simply not care?
"Stop...! Make it stop!" she cried in desperation as her belly grew bigger and bigger, making her look overdue to deliver a set of sextuplets. She was so big and pregnant again already, the thing inside of her huge and strong, kicking and tenting out spots all over her big belly. The alien she'd birthed earlier only continued to gulp down her breast milk, all while rubbing her growing baby belly.
She didn't know how much time passed before she felt the first contraction. "No, god, no, not again...!" she whimpered, despite knowing that there was no other way for this to end. More contractions came, accompanied by more movement and more rubbing all over her distended belly. A particularly painful contraction came on, eliciting a scream from her as she felt her water break once again.
As if encouraged by her going into labor, the alien latched so tightly onto her teat suckled even more vigorously, as if it were determined to drain her tit before she could manage to give birth.
Once more, she felt the huge head passing through her cervix and into her birth canal as her womb contracted, making her scream as she felt the irresistible urge to push. This time, she could feel more progress with each push, her body having been stretched wide earlier on. Still, the discomfort and pain remained, and she screamed through another long, hard push as the head worked its way down and began slowly easing into a crown.
"Fuck, it's crowniiiing...!" she screamed, gritting her teeth as she pushed again, the massive head bulging her pussy to an impossible size.
The first born continued its nursing, squeezing and pumping her breast for more milk as she labored. It was only a small comfort that her labor was progressing more quickly and easily this time. What if another one began growing after she gave birth to this one? And another after that? What if she was stuck giving birth to huge alien offspring until her body just gave out?
She didn't have time to really think about it, another contraction urging her to push. The head was just as big as the last one, and she gasped as it burst free with a splash. It immediately turned, and she shouted as she pushed and felt the shoulders pulling her wide.
"Get... out... of... me!" she screamed, pushing with everything she had. The alien in her belly thrashed inside of her, equally determined to be free of the confines of her womb. Milk gushed from both breasts, the unattended one spraying it everywhere when she pushed.
Panting and wheezing as she desperately tried to catch her breath, her body forced her to push again. She pushed and pushed and pushed, as hard as she could, until finally, she felt the shoulders pop out. She groaned with momentary relief, before her belly contracted again and the alien kicked and squirmed while stuck in her birth canal.
All she could do was breathe and push, over and over again, the creature's body slowly inching out of her with every contraction. She could only see the alien breastfeeding from her, and her gargantuan pregnant belly, jostling with the movement inside as its inhabitant twisted and kicked as it struggled to get out. She could only imagine how it looked hanging halfway out from between her legs, the rest of its body confined inside the cramped quarters of her belly, stretching it from within.
Pushing hard, she gasped as she felt the arms finally come out, and grabbed the headboard behind her once more, this time knowing what to expect. Her feet planted firmly on the bed, she held tight and pushed as the alien she was birthing gripped the end of her bed and began sliding itself out. "Get... out!" she groaned as she pushed, squeezing out more and more of its body. Her belly was much smaller, yet still far bigger than a normal pregnant belly, when she felt the hips come out, shortly followed by the legs.
Sighing, she leaned her head back, hoping it would be over soon. As she felt something warm and wet envelope her breast, she gasped, looking to see the thing she'd just birthed had latched onto her other breast. Again, she tried to free herself from them, but they were so strong, they didn't even react to her efforts.
Each alien now had a hand on her post-pregnancy swollen belly, and her eyes widened with fear. "Please, please, not again..." she prayed, just as her belly began to expand once more.
A monster breaks into your apartment, and you successfully hide while your roommate wasn’t so lucky.
Every day and night since then, you can hear them moan and cry, regardless of whether you have separate rooms, as their belly rapidly swells huge with the writhing babies the monster impregnated them with. Do you think maybe you should do something about the situation? Hopefully the offspring don’t immediately target you once they’re free
Monster that gets into your house while you’re out and decides to make its home there. It will consider the entire house and every permanent item in there to be its own domain and belongings. Including you.
At first, it might move into the basement or attic. You won’t notice it’s there until it decides to enjoy its new toy for the first time. Emerging from its hiding place to pin you down. Mercilessly thrusting and cumming into you without a second thought to your pain or fear. When it’s finally satisfied, it leaves you a cum-stuffed exhausted mess as it slinks back to where it came from. And this is only the first time of many.
Whenever you’re home, you anticipate to be grabbed, fucked, and stuffed at any point no matter what you might be doing at the time, even if you’re trying to sleep. The monster eventually grows bolder, too. It moves out of the basement/attic, maybe sleeping in your living room or even the bedroom with you. Fortunately it has no interest in your belongings, just you and your house. So you get to continue with your day to day life, if only constantly sore from the monster having its fun all the time
Well, until you get pregnant, that is. Maybe you don’t think this was a possibility since you’re entirely different species, but soon enough you can’t ignore the squirming in your swollen belly. The babies quickly grow huge and heavy, and going out in public gets unreasonably hard, hauling around your belly full of inhuman creatures as people stare. Soon enough you can’t even leave the house at all. Barely able to move from the bathroom to the kitchen as the monster’s offspring thrash and fight for more room that your stretched and strained belly can’t give. Each of them are already bigger than a human fetus, and there’s so many of them.
The monster’s behavior changed too, constantly attending to its babies. Not you, just its babies. Constantly licking and caressing your overtaxed belly and feeling its offspring move. You’re too exhausted to push it away, barely able to do much other than groan and whine in bed as the monster licks your swollen belly. And soon after you give birth, it’s back to normal. Fucked and filled constantly, but now with the knowledge that it actually can impregnate you.
This could go on for years. The monster doesn’t plan to leave your house. Eventually you’re being fucked against your kitchen counter, belly stuffed with gallons of monster cum. Thinking about the next set of babies that will soon be thrashing inside you as dozens and dozens of others already fill the house
Thinking of tentacle monster that fucks you from the inside out. It forces its way inside your body, living in your stomach or womb. And from there it will occasionally use its tentacles to rail your holes whenever it pleases without warning
From in your stomach, you could just be buying groceries when suddenly a tentacle jams up your throat into your mouth. You gag and choke on it as it fucks your throat, and if you don’t want people to pass by and see a tentacle thrusting in and out of your mouth, you better keep your jaw clenched shut so it can’t make it past your teeth. You can try and struggle to swallow it back down into your stomach, it but fights you every step of the way, and the feeling of your throat constricting around it only helps please it. Alternatively you can give it lighter swallows and suck on the tip in your mouth to make it cum faster and therefore stop sooner. And if you’re not exceptionally skilled at swallowing up its seed faster than it can pump its load, you’d better find somewhere for it to go. From an outside perspective it’ll probably look like you’re vomiting up cum. But once it’s over, it’ll slowly recede back into your stomach
From in your womb, you could be sitting on the bus waiting for your next stop when you feel it start to press hard against your cervix, and you only have a second to brace yourself before it shoves itself into your pussy and starts thrusting in and out. There’s not much you can do without drawing attention to yourself, so you have to just sit back and try not to moan out loud. Sometimes it’ll stick further out to stroke different segments of its long tentacles, snaking around you. Someone might notice the moving shapes under your clothes if it extends far enough. Eventually you hobble off the bus and find a private place to slip your clothes off, and jerk off the tentacle to help it finish. Then you lean against the wall, whining a little it pulls all the way back into your womb, rubbing your insides all the way.
Idk something about the helplessness of the monster fucking you being the safety of the one place you can’t even try to do anything to it: Inside you. And if anyone knows where to find content similar to this please lmk. Doesn’t even have to be a tentacle monster, just anything fucking someone from the inside
Getting fucked by a monster and being able to see and hear its balls. Unbelievably huge, throbbing eagerly and gurgling from the gallons of seed packed inside. Just so you can have an idea of how much you’ll be filled with when it finally cums
Someone’s at the front door. Maybe a friend, family member, neighbor, whatever. They ask if you’re okay, because they haven’t heard from you in awhile and just wanted to check on you to make sure nothing bad has happened
You’re pressed against the other side. There’s a monster with you, huge and strong and pinning you to the door. Its cock is buried balls deep inside of you, so big that it bulges out your abdomen, visibly throbbing from the outside. Your belly is red and swollen from gallons of thick, hot monster cum. The monster moves its hips, its cock stirring up your insides. It’s been using you for days on end, so long that you can’t remember what it feels like to be empty.
You tell the visitor that you’re fine. It’s just that you’ve gotten really busy or something. Any excuse to make them stop worrying and decide to leave. It’s a struggle to keep yourself from moaning and crying as you talk. Maybe you could be saved if you asked for help. But you don’t know what the monster will do to you or the visitor if they find out.
And so, the visitor leaves. You return to your gasping, screaming, and moaning as you’re ravaged by the monster’s cock. It thrusts in hard, pumping extra seed into your already overstuffed womb. It roughly grabs your swollen belly, making you squeal as the cum loudly sloshes inside you and it begins thrusting its hips again. Who knows how much longer this’ll go on for?
A man that'll cum in you multiple times then cockwarm you full of his cum until you're so relaxed you fall asleep. Only to wake up not long after to them thrusting deep inside you not caring if you're awake or asleep, fucking their cum deeper into you whether you like it or not
Big fan of ugly, gnarly and massive cocks on monsters. Cocks that scare the shit out of you when they are in your face…and make you throb at the idea of being fucked by them to the point your hole is actually a gaping, dripping, loosened up mess. Bumps and ridges and feelers and other weird appendages on it that rub so deliciously and make you cross-eyed😩😩😩
