Summary
This is a story about some of my favorite fandoms interacting! This has been years in the making, so I hope you enjoy! This was inspired by Game 6 mainly but also by many other crossover series I have watched/read. Some of them I'd rather not really associate with due to the creator though TwT. Eventually I plan to adapt it into a comic and post it on tumblr, but for now, I decided to write it here on Ao3.
I will likely edit older chapters later, but for now, I have started with the 5 chapters and next month I will post the next chapter and I plan to have one chapter every month.
I really do hope you enjoy and if not, I still hope you have a lovely day!

Summary
Prompt fill:
"Wheatley (any form will do) succeeds in killing Chell somehow. Unfortunately for him, the Chell came back- as a ghost. And now he can't ever get rid of her."
Alternately, "Wheatley is an idiot, Chell is dead and pissed, and GLaDOS is still a potato."

Summary
Summary: Waking up as a female version of Severus Snape during her teenage years was a dream come true.
Being part of a multiversal slave company like Waifu Catalog... not so much. Luckily, I didn't have any responsibilities to fulfill with them, so I could live my life freely.
If that meant learning different magic systems from different worlds like I'd always dreamed of? Well, this was the best thing that could have happened to me.
...and if I got one or more wives, that would be great.

Summary
Resumen: Despertarme como una versión femenina de Severus Snape durante su adolescencia, fue un sueño hecho realidad.
Ser parte de una compañía esclavista multiversal como lo era Waifu Catalog... eso no tanto. por suerte, no tenía ninguna responsabilidad que cumplir con ellos, por lo que podía vivir mi vida libremente.
Si eso implica a aprender distintos sistemas de magias posibles de distintos mundos como siempre eh soñado? bueno, esto era lo mejor que me pudiera haber sucedido.
...y si conseguía una o más esposas, sería algo bueno.

Summary
It was not a new world that awaited us next.
But six of them—each with its own mysteries, its own challenges, its own stories.
From hunting vampires in a fast-food joint to standing in court before the Iron Throne.
From a city in the frozen waste ruled by a genius to a lost city of gold.
From a simple farm (and gay porn studio) to a Victorian Gothic romance among the dead.And yet, it is all the same story.
Interwoven.

Summary
Chell has (re)established herself a corner of the Relaxation Centre after her return to the surface proved to be less than brilliant and actually rather lethal. Whilst neither of them are thrilled with this setup, it gives them the chance to learn to coexist. A little montage of all of the human-y rituals Chell manages to fill her more relaxed Aperture days with, despite now being so far removed from, literally and figuratively, every other human on the planet.

Summary
Hello fellas, this is a collection of relatively short smut pieces written between Ventiplus and ShadyManBooRadley.
We have collabed numerous times for numerous smut pieces so we decided to make this fic for those collabs that aren't quite complex enough to reach a high number of words as well as being an opportunity to work with less common characters in smut. (No Jaune X Harem here I'm afraid)
What that means is that the porn without plot tag is pulling over time, this collection will most likely be composed of mostly silly cheesy smut, if that is of interest check it out!
