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?
Traveling through the woods when you take a few wrong turns, and now you’re hopelessly lost. The map doesn’t help at all, and you’re stuck wandering where no one ever goes.
Well, until you’re picked up by what seems to be a man. He looks you up and down, decides you’re good enough, and pins you to the ground to tear your clothes off and fuck you full of his seed. His strength and stamina seem inhuman, and he cums more than any person should be able to. Enough to make your belly visibly stretch and swell. No matter how you struggle, you can’t fight him off even an inch, and he manages to fuck you senseless in only a few minutes
When you come to again, he’s taken you back to his mansion in the middle of the woods, and his seed is still slowly leaking out of you while you’re locked in a bedroom. You’re trying to come up with a plan to escape while you drain his seed out when you feel movement. There’s something else inside you, squirming and writhing. It’s growing so much faster and moving so much more than any human baby should be. When you notice him watching you from a window in the door, there’s a strange look in his eyes.
That human disguise hides a lot. You don’t know what he really is. And if you don’t know what he is, how are you supposed to know what’s growing inside you?
“Doctor, what are we doing here?” The assistant questioned, uncomfortable from the several minutes spent crawling through bushes.
“Shhhhh.” The doctor whispered, pressing a finger against the assistant’s mouth. “We’re in monster territory. If you attract one of them, I’m using you as bait so I can escape.”
“What?? Why do we have a bodyguard, then?” The assistant questioned, lowering their volume to match.
The doctor looked at the silent and stoic bodyguard next to them, then back at the assistant. “The bodyguard is for humans who try to mess with us. And manual labor. Not for fighting monsters. Since when has SPF ever been about fighting monsters?”
“Since the last ten times you punched a monster and yelled at the bodyguard to kick its ass before it breeds us.”
“Oh yeah. Well we’re still a research team first and foremost. Stop questioning me.”
“Yes, doctor.” The assistant sighed as the trio ventured further into the bushes. By now, they could hear something odd up ahead. The rhythmic movement of something wet, and the sound of a person’s pained and pleasured moans. It wasn’t long before they reached a vantage point where they could look over a clearing where the source of the sound was.
There, sat against a tree, was the monster that the doctor had been looking for. It was huge bidepal creature, at least 8 feet tall. Its powerful muscles flexed with every movement, one limb containing vastly more strength than a human had in their entire body.
And in the monster’s hand, it held a human by the waist, impaled on its cock as it roughly moved them up and down like a glorified sex toy to stroke itself off. The size of the monster’s cock was hard to estimate, constantly buried inside its prey, but the human’s abdomen bulged out from the mass of the thing inside them. The sloppy wet noises of the human’s ravaged hole echoed around the clearing, almost as loud as their desperate and overwhelmed cries and moans. They weren’t struggling, weren’t calling for help, already more than exhausted by now and unable to do anything other than take it. Besides the hole torn in their pants, their clothes were mostly intact. Hiking boots, a tight shirt that did very little to obscure their bulging abdomen, and a belt that was straining against said bulge.
“Seems like this one didn’t waste any time getting to the main event.” The doctor commented, producing a notepad and pen to hand to the assistant. “This could be the monster’s natural behavior, or it may have been particularly pent up.”
“Doctor, shouldn’t we help them?” The assistant asked.
“Nope. We’re here to observe and dip.”
“Seriously??”
“You wanna go down there and help? Be my guest.”
They looked down into the clearing again. The caught human was completely limp with their eyes half closed, their mouth hanging open as completely uncontrolled moans spilled out. It wasn’t clear just how long the monster had been using them. The assistant wrote down the previous comment.
“Good! You’re still smart enough to be my assistant. Anyways.” The doctor continued to prattle off various notes and details about the monster, all of which the assistant diligently copied down. But it was a struggle to pay attention to the doctor’s words. The sound of the caught human’s hole being ravaged sent shivers up the assistant’s spine, and the doctor never spoke as loud as those defeated moans. Still, the assistant kept up with all of the doctor’s voiced thoughts, never falling behind.
Meanwhile, the doctor kept their eyes glued to the scene. Mostly at the bulge that grossly distorted the human’s abdomen. They had the fit, athletic body expected of a hiker, which only made the bulge all the more obtrusive. The monster’s cock hammered in fast and hard, stretching them out with every thrust like a cocksleeve only made for the monster’s pleasure. And it somehow began to move even faster. The monster’s snarls and growls grew louder and louder, rivaling the human’s own moans.
“Oh look, watch this. I think it’s almost there.” The doctor encouraged, patting the assistant’s shoulder then lifting their chin. Just in time to watch as the monster violently slammed their cock inside all the way to the base. The human’s scream was drowned out by the monster’s deafening roar, balls squeezing and cock visibly pulsing through the human’s abdomen as it pumped out giant loads of seed. The bulge quickly disappeared behind the human’s rapidly swelling belly, not meant to hold so much at once. Their scream became a series of strangled cries, voice straining out every time their belly bulged larger and larger with each pump. The belt creaked and strained, until it finally gave with a loud snap as the buckle was launched away. The shirt was quick to ride up after, bunching up on the human’s chest. Very soon, they looked like they were on the verge of giving birth, yet still stuffed fuller and fuller as the monster showed no signs of stopping just yet.
Parts of each pump would spill out. Making a mess on the ground, the monster’s balls and legs, and the human’s legs and expanding underbelly. But for every bit of seed that escaped, much more would be packed inside the human. Their belly reddened from the pressure, their eyes rolling back as drool dripped from their mouth, body seizing and shaking. Every time it seemed like they couldn’t possibly fit anymore, another load swelled them up again. But eventually, the flood did slow down, and finally stop. The human went limp again, their head hanging. They looked much more than pregnant now. Their cum stuffed belly was about as big as their body, the bottom of it resting on the forest floor.
The human’s respite didn’t last long. It only took a short while before they were groaning again, barely shifting in the monster’s grip. The pressure in their stuffed insides kept them from being able to relax. Any drop of seed that hadn’t escaped earlier was now trapped inside, the monster’s cock acting like a plug. Suddenly the human started letting out strained, weak cries, almost in a timed pattern, panting in between.
“The monster must be throbbing like crazy in there.” The doctor commented. “All that and it still isn’t finished.”
“They’ll explode if this keeps up! Look at their stomach, there’s no way they can handle twice that.” The assistant protested.
“I doubt it. Humans have gotten filled bigger than that.”
And just as the doctor said, the monster started again. It was slow at first, moving its cock around in the human’s ruined hole despite their protesting cries, but it picked up the pace quick enough. The human was practically being squished, monster from behind fucking them against their own belly. Rocking it back and forth, the gallons of cum inside them loudly sloshing and gurgling alongside the sound of the human’s moans and their hole being ravaged again.
The research team continued to observe the scene from the safety of the bushes. It was going to be a long observation.

Once again, I wrote all this in one sitting while tired. Excuse me for any mistakes or bad sentence structure. Someday I’ll put my full effort into good writing for this blog
As you can see from this chapter, I’m starting to lean into identifying the research team as characters instead of just a device to start the story. This was my plan from the beginning before I spat out the first test chapter, and I already had them fully characterized in my head since then.
But as you can also see, I really held back on actually showing that characterization outside of their roles (the doctor, the assistant, and the bodyguard) and displaying hints of personality. That’s cause I’m once again testing the waters to see if anyone likes the direction I’m going in.
I do want to lean further into the research team being actual characters. Most of my concept posts are left intentionally vague to appeal to a wider audience that can fill in the blanks to suit them. (For example, I try not to identify genders in concept posts. Interpret it as mpreg if you want, and don’t let the monster’s 12 inch dick stop you from picturing it as female)
But ironically, the wider appeal vagueness does limit me in some ways. It’s a lot harder for me to play around with personalities, relationship dynamics, backgrounds, and other stuff like that without characterization. The SPF research team is my way of eventually stepping into kink stories that require actual characters. Now, I’m not putting an end to my wider appeal concept posts of course. I will be concept posting every time I have a concept to be posted, and that will always be the vast majority of my blog. I’d just like to do more
I’ll probably go ahead with the in depth research team whether I get feedback on it or not, but I’d like to hear if anyone is interested by this. Anyways if you read this far, thank you for listening to my author rambles and I hope my insomnia writing is still good enough to enjoy
Imagine the werewolf curse spreading through bites isn’t common knowledge. When werewolves attack your village, your partner valiantly defends you as you try to make your escape with the rest of the villagers. They get bitten in the process, but the two of you manage to securely barricade yourselves inside your home.
You relax now that you think you’re safe, helping your partner tend to their wound and waiting out the attack as you plan to travel to the next village when the monsters have gone. But it isn’t very long before the curse kicks in, and you follow the sound of pained cries to find your partner writhing on the floor in pain as their body grows and shifts. Teeth sharpening, fur growing, snout lengthening to resemble the monsters that attacked you earlier. When the transformation is complete, your partner only remembers you as their mate.
You try to run, but there’s nowhere to go when every entrance was boarded up to keep the monsters out. They catch you within seconds, tearing off your clothes to ram their cock inside. Nothing in their head but the instinct to fill their beloved mate with pups. No amount of begging and pleading and struggling gets through to them, and they never take a break from ravaging your insides and stuffing you so full of seed that you look overdue already. You’re ready to pass out long before they’re done, and by the time they finish you’re too weak to move a muscle.
Now they’re much gentler with you, laying you on the bed to nuzzle and lick your sore, stuffed belly. You know that soon you’ll be heavy with new additions to your family. There’s no way they’ll let you leave the house turned den now, so you might as well enjoy your new life.
