After searching across the internet endlessly I have found many images, yet only a few being specific to this highly specific fetish. I have also found even far less text stories… the low level of this material is astonishing.
basically orifice invasion / unbirth fetish usually involves some looser vague definition of something going inside, but what im talking about is this:
>fictional story or image
>there is a female (or whatever)
>there are some alien sentient slugs
>they crawl all over her
>they crawl into her pussy
>she tries to stop them or get them out
>stuff her full until she is pregnant
>she cums or whatever
there really isn't alot of this out there. its always "some tentacle fucks some female" but very rarely is there a smaller tentacle or thing that crawls up entirely into and goes completely inside a female where she can't get it back out and it keeps making her cum.
a good example is some girl swimming at a beach on some alien planet and some kind of alien tentacle swims up her pussy.
I hope someone understands what I mean, its just so rare and I'm here to complain and to hope that someone hears me out and this gets more common.
