This might be the greatest doujin with this concept ever made: https://exhentai.org/g/3010152/7f01e3d4cd/
>>
>>11114578
That was excellent wish it leaned harder into bad ending the MC, she lost for sure, but she didn't get it ground into her until she believes she's doing the right thing by giving birth to tentacle rape monsters
>>
>>11114592
I have some ideas along those lines I want Bonno to use in the sequel. I'm considering commissioning him too.
It basically amounts to the tentacles capturing more of the Corps and gaining more and more of their powers and using them to crossbreed itself into perfection. Eventually they would reach a critical mass and would use some of the magical girl's powers to up their intelligence and fuse together into a handsome, manly, tentacle monsterboy form with tons of sexual powers and and an alluring masculine voice that would make Kuon's very femininity throb and corrupt her. She'd begin to enjoy futa fucking other girls with the dick the tentacles would temporarily force her to grow and end the story as the enthusiastic Tentacle Queen.
I generally only like futa of the temporary ball-less sort (because its kinda unfeminine otherwise), sometimes merely ultra-clit futa, but that sort of thing doesn't fit for these breeding purposes; so I thought up an AMAZING futa concept one day.
A futanarization that cannot cum on it's own but instead connects the womb to the the dick and uses the cum of others to ejaculate with. The girl can only cum when the tentacles/tentacle man blasts into her. Fucking hot.
The tentacles would use this to further boost crossbreeding efforts. I really don't like tentacle mouths sucking futanaris off (like in his previous work), I much prefer them shoving that thing into another girl.

I'm even considering paying him to just ~consider~ all my ideas. Haven't had a doujin stoke the imagination like this in a while. I haven't ever even wanted to commission porn before.

Heres a rough list of some the Corp's members' potential powers and the purpose to which the tentacle swarm would put them to:

>Time Stop
Rapid Pregnancy
>Vital Bond (a power thats good for support and team work that synchronizes the vitality of teamates)
Fertilization Orgasm (girl can feel eggs being fertilized, author did this in his previous work)
>Aura Fist (fighting spirit aura ect)
Masculine Essence (puts off an aura of alluring manliness)
>Transformation (like I dunno she turns her arms into blades or something)
Futanarization (no balls, it cums with the tentacle semen stored in the womb instead of making its own)
>ESP
Shared Orgasm (sense link, feel the tentacles pleasure as well and any girl futa/tentacle-fucked. Psychic powers also make the the tentacles more intelligent)
>Confusion
Sexual Sense-crossing (synesthesia, make her vagina taste the sex and find it delicious/make her tongue orgasm when eating delcious things. Nose orgasms from mascuine odor. Lactating feels like ejaculation, nipples tastes their own milk)
>Spirit Fusion (shes like a summoner that summons and fuses familars)
Sexy ikemen monsterboy form (tentacles combine and fuse)
>Siren Song
Arousing Voice (tentacles speak in a otherworldly attractive voice, making one experience sexual arousal)
>Heal
Unending sexual stamina, healthiness. Hymen and vaginal tightness regeneration.
>Thunderfist
Electrostimulation
>Alchemy (support, makes potions and the like FMA style)
Aphrodisiac Mist & Nectar
>Hypnosis
Sleepraping (hypnotic lezing out and getting the MC started on loving futa shenanigans. I generally hate strong hypno shit so use sparingly. Maybe axe it entirely.)
>Teleport
Portals in vagina/womb//around dick/around limbs (Teleports tentacle fetuses between mothers' wombs for more effective crossbreeding. Tentacles bite their own tails and infinitely insert into girls for fun. Portals summoning the futa dicks of the squad into pussies. Psudeo-amputee kinks.)

I am absolutely shocked I haven't seen this before.

>>11115512
I remember seeing something close to it in this one 2d/3d hybrid animation, two times, in one the futa fucked and creampied a girl, only for the girl's ovum to swallow the futa's sperm and return into the dick, impregnating her, and the other is a futa fucking a tentacle monstergirl's bellybutton, cumming inside it only for the mongirl to grow a tentacle from underneath (where the genitals would be, but there's only one hole) and pump the semen back into the futa. Forgot the name tho, but it did also have instant preg into birth

some fun ideas there. i think transformation could have many applications (like a cow girl form, or more intense breast/butt expansion).

>>11114578
this is good shit, thanks for sharing
>>
>>11115664
Thanks. Personally I dislike most overt kinds of body deformation of any kind beyond a pregnant belly and a temp futa. I even prefer to keep a girl's corruption very subued visually. The most that I like to see is a womb tattoo, usually.
I can appreciate monstergirls but I like human girls to mostly stay human just becoming stained with lewdness. Pure human, but warped by addiction to sexytimes is appealing for me. I'm a more /h/ individual, mutation always has to be temporary for me. Pregnant-sex is my primary fetish, but erotic births of human babies are not. Oddly enough tentacle births are fantastic though.
I have my tastes I suppose.

thats fair. i really dont like futa at all, it's about femininity to me after all. i love all processes that emphasize femininity like breast/butt expansion though.

this is a page from another doujin by the same artist, but it has futa later on which is a shame.
>>
>>11116006
Yeah that instance of it has balls and is being sucked off by a tentacle so meh. I only like futa if it's temporary, ball-less, and spends most of it's time unseen and shoved inside another girl. Preferably MalexFutaxFemale.
How do you feel about ultra-clit futa?
Ultra-clit is preferable depending on the artstyle.
>>
>>11113345
I followed him because his BE stuff was the best I had ever seen. So when out of the blue he started posting a few preg things I was so excited. I even got a commission from him. But then after that round of commissions he stopped posting. It's nice to know that he didn't just quit making art and has been working on the mod this whole time to follow his passion at least.

I should check out that game so I can play the mod because I assume he had to draw a lot of art for it.
>>
>>11116069
ultra clit is really just futa lite. i don't like it at all. whether you give a girl male genitalia or distort her genitalia to look male, it still breaks from what it's about for me.

>>11116083
yeah, though i wish he'd also just draw stuff. a lot of the art for his mod is repurposed patreon stuff so it might be new or it might not be. check it out either way.
>>
>>11116091
I can respect that. I dislike more of the flavors of futa people typically put out there than I like so I lean more towards your camp than the other.
>>
>>11116006
>i love all processes that emphasize femininity like breast/butt expansion though
This is what it's all about for me. Not just rapid expansion of the belly but everything else that would typically happen during pregnancy happening at once.

it's a gray area because it's a creature summoned directly into the womb, but it is the womb getting used for its intended purpose. let's allow it because it's rare (and the art is good).

>>11119351
It also meshes well with >>11116433 since getting doused with all sorts of otherworldly energies would let a woman's body go well beyond the norms to support its new occupant/s. That could even be the entire point, like some vain sorceress making a pact with some femininity-aligned entityto to gain beauty and power in exchange for being a conduit and incubator and providing other..."services and benefits".

No thats fine. I consider that part of the fetish, it doesnt really matter how it gets in there, something is growing rapidly inside her womb. Its just a shame unlike this >>11119991 it doesn't show her body reacting to it at all by her boobs getting bigger or something.

I just remembered there was an eromanga from a while back, it took place at a university and the focus was on a popular woman that was a student there, who had time stopping ability. She used it to have sex with guys secretly, but as the story continued she would meet up with a male student that gained the same ability and after some time raping each other, they both got into stopped time with each other, and proceeded to have sex. After she got cummed inside of, she got immediately pregnant, and rapidly gave birth, and the child grew up rapidly. Does anyone remember the name of this work?

trying to hunt down a kino belly expansion comic i found a while back but cannot find if i downloaded it or not
was a girl who was getting "pregnant" despite not recently having sex, her belly just keeps getting bigger and she gets an ultrasound and theres nothing inside, eventually at 9 months she expels it and its just goo, later on shes going "wow, that was weird, kinda fun tho, glad its over" and tries to put a belt on and it doesnt fit and she goes "uh-oh"

Did anyone else first stumble upon this kink through an episode of Fringe? It used to air on Fox, if I recall correctly. The setup for the episode is similar to >>11124192, but with no time shenanigans.

>Dude with a weird condition breaks "the rules" and hires a sex worker
>Has sex in a hotel room
>Mere minutes after, the woman feels like she's going to throw up
>Rushes to the restroom and pukes, then notices her belly swelling in the mirror
>The dude dumps her at the hospital a few minutes later
>Confuses the doctors when she claims she wasn't pregnant a few minutes ago, when she's already in labor
>She gives birth normally, but the kid begins aging rapidly
>Dies a couple hours later as an old man

This is all in like, the first few minutes of the episode. I'll have to look for the scenes of that X-Files episode, thanks!

Family Matters had a later-season what-if episode where Steve Urkel and Lara Winslow hook up and have an entire polka band's worth of kids (literally) and one of the last gags of the sequence is her parents wondering how they managed to have so many. Cue steve kissing Lara and her instantly growing to full term. Gave me the twofer of rapid preg and intimacy-triggered expansion, cuddling and kissing and passionate sex that causes a girl to blow up like a meat balloon as her partner literally pours all their love into her.
