you are now a bug/flesh pocket monster with the sole purpose of capturing cute high-school girls and keeping them with you as long-term rape toys. what features would you have so that they can't escape?
>example in pic
Well, for starters, the capsules would be made of bone, not gel or glass or whatever that is. It would however be filled with gel, which would slowly make them enjoy being my toy (pic is mildly related to this).
I would bait them with cute cell-phones.
The first time I read this, I thought you were saying that the things in your picture are pokemon.
I would so catch that pokemon.
A nigh endless selection of tentacles of different purpose to pick from so that they wouldn't WANT to escape.
>a quartet of excessively strong ones for capture
>a dozen hair-thin ones that channel electricity for stimulating her brains pleasure centers
>two suckers with proboscises and massagers for draining her breasts and injecting mind-addling pheremones.
>a hundred or so miniscule firm ones for massaging and teasing.
>four thin dexterous ones for encircling her nipples tongue and clit
>a hollow, bulbous one for stimulating her anus and removing waste
>a single one that can adjust in size to achieve various desired thickness with a pointed tip and various wriggling filaments to provide maximum stimulation of her vagina while irrefutably implanting my seed in her nubile womb.
>several more thin ones that secrete a sensitizing agent to gently invade any orifice I left out; ears, urethra, eyes once she is sufficiently broken.
like full on cocaine addiction.
they won't leave because they actually need to remain, or they'll go into withdrawl. it also gets absorbed through the skin, so i can shoot it at any runners who try to get away from the rape train.
First, some active camouflage, be a lot easier to capture girls when you can blend in with the environment. Next some kind of spray that creates a fine, almost invisible mist that when inhaled causes drowsiness or similar immobilizing effect, so that a girl can be captured without alarm. Now some strong appendages, tentacles work great for this, particularly if they come with a means to have an incredible grip(such as suction cups or enough tiny hairs to make use of the van der Waals force), both for grabbing and carrying girls, and for climbing. However tentacles aren't the most bug like thing so a set of limbs that have a great many segments could work as well. At this point you need some means to contain the captives, for this I suggest some form of silk, rather than a body cavity due to silk allowing you to store girls without having to carry them around. Lastly some means of feeding the girls, for this I would suggest either a bodily product of the monster, or possibly filling their stomachs with unfertilized eggs.
Regular injections of a pair of long-acting drugs; one that acts as a powerful aphrodisiac, and another that prevents any orgasms unless counteracted by a chemical I secrete. Even if they do get away, their horny bodies only I can satisfy will bring them begging back to me, deliberately offering themselves up to feel release again.
Yeah, took me a while to realize it was supposed to be (Bug)/(Flesh Pocket) (Monster), not (Bug/Flesh) (Pocket monster).
What would a Flesh-Type Poket Monster even be like?
I prefer the classics--I'd just be a vampire who either visits the girls in their bedrooms or lures them into my tomb after dark. I would use basic vampire mind control (and maybe a few "I'm just like Edward, I won't really hurt you"s) to lull her into a false sense of security. Under my power she will begin to feel a profound urge to fuck, which I will quite gladly offer to fulfill. This way, I'll know whether or not to bother keeping her after I'm done; because then at the moment of climax, I will bite down on her soft little neck and immediately begin gulping down all her blood. She'll try to scream, but the effects of my mesmerism, her orgasm, and the bite itself, will all cause her to relax and drift off into a pleasant and shuddering little oblivion. Once she returns, however, I will make her my new vampire sex slave: her first task will be to help me recruit as many of her friends as I am interested in. In this way my harem will grow with the centuries.
And no tentacles involved.
I'd want to be able to produce smaller creatures with highly developed nervous systems that I could implant them with that burrow into their womb and attach to their nervous systems allowing me to directly stimulate their nerves to torture them with pleasure, turn them into meat puppets, or just mind control them to be willing, or be sleeper agents to recruit more.
Stealth instincts to capture unsuspecting human female beauties who will never be seen again
Fine, long, forceful tentacles for capturing victims quickly and moving about quickly
A large cocoon body that can house her body and immobilize it by "absorbing" her members -- she's kept all opened up and exposed and vulnerable for maximum exploitation
Internal tentacles to manipulate her captured absorbed body
Internal structures that permanently plug into her pussy and fuck her continuously forever
Internal structures that permanently plug into into her breasts and ass to extract milk and shit
Internal structure that permanently plugs into her moth to orally fuck her and force feed her
She's kept sensitive, aware, horny and lactating by chemicals, hormones and pheromones secreted
As a defense mechanism, she becomes so integrated with my organism, killing me will inevitably kill her as well
Can maintain life inside cocoon indefinitely for as long as I can obtain food to sustain her organism
She will be sexually exploited until the moment she dies
Have means to chemically kill the bitch quickly if she turns out to be low quality -- she becomes food for the next one
I'm implant a simple parasite that subconsciously prepares them for breeding and leads them to my breeding ground. After they're impregnated they'll return to their overall normal lives but be unconsciously spreading my parasites around to be bred by me. My children would be small in the womb to avoid external detection and slip out at an opportune time to create a new breeding ground.
I have pastas of previous posts ready

Is there anything sexier than the notion of something that evolved specifically to fuck women as if it was the entire purpose of its existence
It can't be reasoned with, it doesn't care who she is or if she does or doesn't want to get fucked, all it knows is it's going to fuck her and it It's so disturbingly efficient at it, if she comes across one she's as good as raped
Their grotesque bodies are purposefully sculpted by nature so that they are able to extract as much from their victims as possible, to parasite her as efficiently as possible, which ensures their survival
Once this meat catcher's done weakening his fairy victim, all he's gotta do is bring her into itself and it'll mercilessly stuff her full of larvae. It doesn't care that it's going to hurt a lot, the first thing it does is force a thick fucking probe straight into her ass -- it doesn't matter that it's ruining her ass in the process. Then it starts to dick her repeatedly as if to provide her some sexual entertainment as payment for becoming its personal breeding sow
Not quite what OP was talking about, but what the hell: I was thinking of a microscopic parasite, a little like Toxoplasmosis, that more or less turns a certain percentage of it's victims into this. When your infected your body starts changing, you pack on muscle, you start getting taller, if male, in males your dick starts getting bigger in females your breasts enlarge (the pseudo-penis comes later, once the mental changes kick in). Everything is great for you at first. Then your mind starts to go to strange places. You find yourself becoming obsessed with the idea of possessing people (I know op said women, but I'm thinking the parasite is not going to be picky about who it infects). You are massively, mind foggingly horny all the time. It starts becoming difficult just to get through the day.
You become massively promiscuous, as you can sate it with willing partners, at first, but after a while willing partners are no longer attractive and you can't find any satisfaction in them (they've been infected already, and the parasite wants to spread far and wide). Some people can keep it under control. You can't. You find yourself stalking, drugging, and raping anyone you can get your hands on. Nothing feels as good to you as taking a new person as your victim, no matter who or what they happen to be.
Things usually go very badly for hosts at this stage, but some have been known to last for years by keeping a group of captives to use as human fleshlights in order burn off energy and allow them to keep up a facade of normalcy while they search for fresh victims.
Toxoplasmosis infects at a cellular level (the individual protozoans are roughly the same size as a red blood cell) and is blood borne after the initial infection through the GI tract. Plus, really, if history is any guide the perfect machine for raping humans is other humans. Why bother reinventing the rape-wheel?

Do you have more?
that pic is so hot. imagine the girl desperately struggling her arms and legs trying to break free while she has her entire body played with. the thing on her mouth could insulate sound perfectly, so even someone standing beside her would only hear the sound of sucking and groping
If she gets caught up in it, there's no hope for her anymore, the monster can defeat any resistance she might put up and after he's done with her she won't be able to put up any resistance -- all that's left for her is eternal fucking until the end of her life
So basically, I'd be of a species of creature that relies on humans as part of its body system. Basically, we cannot process a certain nutrient we need on our own, but the human female body does have the ability to do so.
Basically, during adolescence, I must capture a woman without hurting her and integrate her into my own body. In exchange, she is provided with all the nutrients she needs to survive - all that I need from her is something that her body doesn't actually need herself. She's just a processor, not a source of energy; she actually is a drain on my own vitality since I have to keep her alive.
However, this is more than a reasonable requirement. Basically, once I've captured a woman, she's stuck for life. Her arms and legs are restrained, and I have tentacles stuck through her mouth and ass permanently. These both provide her with nutrients and allow me to excrete her waste outside my own body. She will remain inside me, alive, until I die, at which point she will as well. Even if she wanted to commit suicide she couldn't. Even if I wanted to release her, I couldn't.
The nutrient I need is actually harvested through the vagina. Whenever I need it, I just fuck her until I have what I need. Usually, this is the sole source of pleasure for the girl, and the girls usually end up anticipating the harvest.
This one the other hand fits the description it seems.
This woman was preyed upon by this plant-like monster -- engulfed and concealed within its large petals inside of which unspeakable natural horrors would take place
The creature is not capable of simply eating her -- it's not a hunting creature. While it needs sustenance, it can sustain itself from the nutrients of the soil for extended periods of time. However, its highly evolved organism needs more than basic nutrients to survive. Females of various species are notable providers of such nutrients. Human females are able to provide the byproducts it needs to survive
This one simply happened to go a little to close to the plant, giving it the opportunity to arrest her. The plant disables her reaction with aphrodisiac substances and by sexually stimulating her -- she's left overwhelmed with sensation and easy piece of work for the being to take advantage of
The thing gobbles her up, takes her into itself, brings her into a new world, its world, created for the full time exploitation of her body, a world that she enters almost willingly, and then the extraction begins
The first thing to happen is the harnessing of her large tits. To the organism, they are like vast lands ripe with petrol -- begging to be extracted and exploited. Like a cow's udders, from which valuable extract is acquired for its use. It rapidly attaches one of its basic anatomical features to them -- large hollow tubular protuberances extending from the base of the plant, characterized by their visceral texture -- full of villi -- and highly muscular. They are also used to trap and manipulate her legs in order to prevent large movement.
The large tubes are a natural fit for her chest protuberances -- it pretty much requires large breasts to function, as the large volume is necessary for creating the seal and enabling the suction mechanism used to extract motherly milk. The villi provide direct stimulation to the boob -- as if tasting it -- and they secrete a curious lipophilic liquid that is locally absorbed and is believed to stimulate her mammary glands into producing precious liquid completely independently of her body's endocrine system -- she's going to lactate whether she wants to or not.
The structures also continuously stimulate her boobs, their large muscles being used to pressure them, squeeze them, softly chew them up -- when coupled with the aphrodisiacs, some subjects were reported to have orgasmed from the mammary stimulation alone
The monster is not just interested in her milk produce -- it's also getting busy at her nether regions. From another tube-like structure extends various tentacles, which are sensing, probing her urogenital region -- it wants to delve deep inside her body and look for stuff to absorb: vaginal fluid and discharge, urine, feces, anything that she won't have any use for and that the plant itself will happily accept, and it will probe deep for those resources
The more time passes, the more deeply integrated the woman becomes with her new host. Her now useless limbs are bound to prevent resistance and are used by the organism as fixation points for her body, pillars that hold her where it wants her. Their position and orientation is tightly controlled and manipulated
Eventually the basic tube structures go away and make way for highly specialized structures. A large flower-like structure opens and pulls her pelvis close to its root -- work needs to be done. Large probes of various large calibers promptly work themselves into her orifices, not even her urethra is spared.
Her asshole is forced wide open by a suction tentacle probe, her sphincters are not respected. It works itself into her and through her rectum until it reaches the sigmoid colon where feces are stored, the prime position for capturing her waste. The tentacle often repositions itself and moves about which invariable gives her stimulation
An even larger, thicker tentacle penetrates her vagina -- this one has an specialized head that is able to emit more lower-caliber tentacles. These are used to penetrate her cervix and access her uterus and ovaries, for unknown reasons. The large vaginal tentacle is also capable of altering its volume as a whole or in individual segments, like an annelid organism -- female vaginas are most sensitive to distension due to being filled and unfilled with volume and this act, performed with varying, seemingly random inflation and deflation patterns, provides intense vaginal stimulation required for high volumes of juices to start flowing
The tubes milking her breasts are replaced with specialized suckers and a tentacle works itself into her mouth to feed her whatever nutritive substances the creature can provide, thus closing the active parasitation loop of this biological system.
One has to wonder if the women will eventually come to like this arrangement after being continuously being made to orgasm in the most inhumanly perfect way possible, continuously. and all the time They probably experience this deeply deadly feeling at first -- like their lives are over. Over time they probably come to accept it in some form, as if their brains were rewriting themselves to better fit the environment the organism put them in, to better deal with the stress. It probably has to tune it out somehow, maybe it shuts itself down in some parts
Such is the power of these organisms. They're parasites, but they're not smallish flowers that grown on some tree -- a mere thorn on their side, an annoyance. They take females -- highly complex human beings with hopes and dreams -- and they reduce them to a quivering pile of orgasms and milk. It does not matter who she is or how she feels about it -- they all get fucked just the same.
One wonders what rescuing such a victim would be like. Assuming it's possible to take get her out of the monster, would she even be the same? Would she even still be human
Will her brain even work, or did the monster break it? Is she still capable or rational thought or does she recoil at the touch and orgasm at the slightest stimulation? Does she miss the aphrodisiac substances and suffer withdrawal symptoms
One has to wonder if they'd not be happier in the monster than if we tried to reintegrate them in our world
Reading your stuff has me wanting to get pulled in by one of those things ASAP. Thank you.
Goodness is there anything sexier than the notion of a superior creature literally hunting and making a trophy out of women
The shapeshifting slimy creature goes out to hunt, finds a nice looking woman, catches her and immobilizes and gags her as if it wanted to ensure nothing but lewd sexual moaning could ever come out of her mouth. Now it's hopeless for her, she's put in a sitting position as if she was royal queen sitting on her throne -- her shiny new personal sex throne
It adds some support to her head, pushing it forward, as if it wanted to ensure she'd be able to watch what it was going to do to her body. Then it wraps around her legs and pulls them apart, making sure to let her resist a little by trying to pull back before finally defeating the only miserable protection her pussy and ass have besides clothes. It uses tentacles to play with her clothes, playfully thinning them out and gradually revealing her vulnerabilities before injecting her with its volume, filling her cavities whole to her reluctant delight
While all this happens the thing makes no effort to hide or conceal itself or its prey -- it leaves her wide open, as if it wanted to display her to the world, an utterly helpless female overpowered and overwhelmed by this creature who then proceeded to proudly sexually tease her until it gets bored and releases her -- a reminder to the men, about how they failed to save yet another woman who will never again be able to accept their inferior sexual intercourse abilities ever again
By the way, I have a folder with very related pictures, the theme being strong monsters making a trophy out of women and wearing them as cock sleeves everywhere they go, as if they were clothing and determined their status in their society, they go around everywhere with naked spread-legs women around their chests just above their dicks and they fuck those women in front of their peers to show their dominance and her submission
... But that's for another thread
Humanoid, 6'3, 100 kg give or take, stealth based, nothing flashy, made for snatching single prey off the streets or from homes. Take them back to a pre built nest, underground most likely and stick the captured females to wall aliens style only bringing them down to use and feeding them there.
>strong exo-skeleton (think flexible high grade body armour) just in case i get caught can also can camouflage me and hides body heat so i won't show up on thermal camera's
> Able to jump 30 meters and climb along surfaces, strong enough to lift cars, run at 80 mph
> Pads on feet and hands, exo skeleton muffled granting silent movement, dose not hinder movement, very dexterous.
> Plenty of strong retractable prehensile tendrils (7 meters long)growing from my back can be used to snare, trap and stimulate prey
> Tendrils have a variety of ends, [See >>5933416 fantastic posts] but some can pump out two different fluids. the first being a clear thick sticky substance that provides nutrients and staves off physical ageing while enhancing feminine traits, large breasts, curves and hips etc to a limit. The second is a dark black liquid that quickly hardens and is stronger and lighter than concrete, used for sealing up exits and nest building.
> I can release pheromones from scent pits along the shoulders and neck of my exo-skeleton, these calm the prey and can make them become incredibly aroused
> Highly developed senses of sight (360 degree vision), hearing (can detect noises like breathing much easier) and smell (can detect and track females from several miles away)
> Heal quickly, regenerate limbs in a few minutes, severed tendrils in seconds
Holy shit muh dick.
Where can I find shit like this?
I always check gelbooru and tentaclerape and never find shit this good.
I'm also specifically looking for an image of a girl being devoured by two large tentacle toungues. One version shows just the outside but another version shows the girl inside.

Aphrodesiac fluids, hypnosis, and illusion.
> "No, i'm not a tentacle monster! I'm that guy you've always liked but always felt was too good for you. Right, John! I'm John. I just need you to give these fleshy spores to your loser friends and we can spend the rest of our lives together. Baby, there's real, and then there's spectacular. Make your decision."
I would be capable of keeping the female heavily pregnant all the time. There would be times where she would birth for hours but in the mean time she would be pumped with batches of eggs that incubate until ready. The stomach isn't massive, but more than big enough to be easily immobilized by myself
I would exploit their financial illiteracy by luring them in with slogans like "We will finance anyone!" and "0% interest for 1 year!" After they have been lulled into a sense of security and think that they have the advantage, I will sell them the car on a payment plan that, in the end, will charge them for over 3000% the value of the lemon that I have sold them.
>>5937899 If you're >>5938643 we certainly think alike.
continued from >>5937661
As the monster, I can't speak to the girl in me. I know she's conscious, but while I can understand human speech, I can't communicate her. The protrusion I use to feed her cannot be removed and is too thick to be bitten; I have to be able to continue to inject her with the nutrients she needs to survive. I do know that for the first few weeks, she'd periodically make gagging sounds as if drowning on the food I was providing her. I know that by the way her ass clenched on the tentacle that will remain inserted in it for the rest of her life that it was her first time.
When I first captured her, I restrained her arms and legs, totally immobilizing her. She's long since given up on moving them. However, I notice that if I haven't harvested from her in some time, she starts quivering, moaning, trying to thrust her crotch forward. I know that when I use my internal tentacles to play with her breasts, she moans in what seems to be pleasure, and that stroking her clit can bring her to screaming orgasm. She is conscious inside me, perhaps even with some rationality - but both of us know that she has been integrated into my anatomy, that she is biologically just an organ that can't survive on its own now.
Whatever the case, the only respite from darkness and monotony for her is my touch. I carefully ration out her orgasms, keeping them a nice treat for her. It is the only dream she has left.
I am sure, though, that what infuriates my captive most is the theft. I have robbed her of her life. Not her vitality, but her future, her dreams, her ambitions. None of that is left to her.
I don't know what life she led, but I do know that she probably remembers the day when she strayed too far from the camp well. I know that she, a young female warrior, wearing armor that didn't seem to cover much of her skin (which was quickly dissolved by the fluids inside me which cannot harm actual flesh) lost everything that day. What did she have in mind, I wonder. Her hymen was intact; did she perhaps take pride in her unattainability? None of that matters now. All that's left is an eternity as an organ, a lifetime of darkness as a function of another being.
She will spend the decades with nothing but my touch on her breasts and pussy to relieve her from the endlessness. Once, I decided to harvest her in advance and then see how long she could bear it without my touch. After two days, she became restless and squirmy. By a week, I was woozy both from not harvesting and from her endless thrashing about in search of stimulation.
I sometimes pity her, despite knowing what I did was not wrong. She was barely 20 when I caught her, with her whole life ahead of her. I will be able to keep her alive past her normal lifespan, well into her 100s - there may come a time when she has spent thrice as much time like this as she free. All I can do is comfort her the only way I can.
It began as a sense of being watched. She felt eyes upon her in the twilight hours well into the night, that feeling of being watched while walking home, while making dinner and getting ready for sleep. She closed her blinds and locked her doors, avoided the unlit places, cowering like an animal from something she couldn't see.
I am not a beast with claws and shells, tentacles or spores. I'm not blending into the wall, I'm walking between particle-like forms of light, space contorting around me at my will. A physical body isn't needed, I don't require anything material from this female, even if I did I am made entirely of energies and materials alien to this dimension.
The bed would bloom around her, curling up at the edges and folding up to the ceiling. She'd think herself in a nightmare or a dream as the space of her room turned inwards around her, as if trapped in a gerbil ball. She could stand and run, the 'ceiling' infinitely high, but would fly off the foot of her bed, she'd simply find herself back the the pillows at the head of her bed.
I would part the material of her bed, slipping slowly into this realm of hers that I've twisted up like a ball of paper, sucked from her existence into a place where I am more comfortable. The Bed would thin as she looked upon me, my domain of colors and shapes she can't see, a verdant black pasture dotted with specs of common shapes and colors, enough to hint that it's not a void she floats within.
I can't touch her directly to achieve my goal, but I can caress the sensitive nerves in her skin. Her mind would explode with sudden feeling, the sudden surge of heat, cold, pain and pleasure all at once a cacophony to me, but I tune her and find the nerves that achieve the song I want my new little "Songbird" to sing.
I spread my touch across, a lick of my other form sparking a feeling of intense and strange emotions and pleasures. Her mind would find similarities in what she experiences, she would smell sex where it should be, feel heat where it ought to be, taste fluids where she wants them to be, all from the tickle of a being from beyond her dimension, in this tiny spec of her bed nestled vaguely in an infinite expanse of something other than her world.
Her mind's emotions feed me, I syphon her pleasures and pains, explore her desires and find the rich reward of so many strong thoughts and brainwaves, feeding off her mental state. The stronger I grow, sucking from her experiences, the more I can do, the richer her new existence distorts to become. What does she think of me? Would I understand if she said, or knew what I was? Her state of ecstasy and pleasure gives me strength, enough to hunt for another. Two, three, five, ten? Each wrapped up tight in their own cocoons of existence woven by something else outside their sight? Efficiency demands I wrap them together, one by one, to free up my will to capture more, to grow. A cluster of space in a place without matter or energy as they know it.
Some would feed me more in the presence of others, a small harem outside of reality, some fuel me strongest when their bondage of space is a little more literal. Ultimately, shifting matter and space to attune my new batteries to whatever feelings please them best, feeds me most.
Sorry pics barely relevant, they don't exactly make porn of abstract eldrich abominations. Second pic's about best I can do.
>Light bondage as their locked in
Pinch me I'm dreaming. It's nearly every one of my fetishes. Anything similar to this?
I'm super boring and I don't like rape but if I was a tentacle monster I'd just fuck her so good that she'd willingly come back for more.
Well, maybe Id' cheat just a little bit. I would probably use some chemical that would make her orgasms more intense and last longer, so so she literally couldn't get sex as good as that anywhere else.
I'm not into tentacles or bugs or whatever (well, maybe certain monstergirls. And I'd be comfortable being a monsterguy myself), but this thread is interesting.
What are some good prompts for writing for this? I mean you have methods of nurishment, mobility, methods of capture, sustaining the victim indefinitely... basically I want to know all the things that can describe these things.
Then I could program a tentacle demon generator or something similar, and if I'm not lazy enough, put it into a game somehow.
Biology and anatomy can do wonders for your descriptions
The powerful notion is that there is something that the creature can only get by fucking a woman -- there is no other way to get it. So it has evolved obscenely efficient methods of doing so. They capture women and internalize them, nurturing them with nutrients while simultaneously fucking them 24/7 in order to extract as much of that something as possible. The thing invades her body to such depths it's probably not her body anymore
You have lots of room for imagination regarding how they capture the women. You can have them lie in wait as if it was a trap, you can have them use tentacles to aggressively hunt for women, who knows what sexy predatory stuff you can come up with. Past that part is where the sexiness of the fetish lies -- how utterly defenseless and exploitable the woman is. She's at the mercy of the thing, she can't scream, she can't run, she can't escape, she can't fight, she can't clamp herself up, can't even move, she's forced to be 100% vulnerable. That's the sexiest part of it, from then on the monster can do whatever it wants, rape her, kill her, torture her, do nothing and just sustain her, anything it wants, but whatever it does she'll be forced to submit to it
If that's a game element sounds like it could be a vehicle for moral choices -- do they submit to the temptation of having sex with the helpless woman continuously until she dies, knowing that there will be zero consequences for it and in fact it only makes you stronger?
