Oh_Cosmo's Grand Fic List
This is the dumping ground for works I've read.
The master list.
The junk drawer.
These fics stick in my head like a barnacle to a boat, it's a multi fandom guilty pleasure collection that I pray no one I know irl sees and reads.
Some fics are just "hey that was cute!", others are "I'm definitely going to be thinking about this in 3 months, I don't want to lose it", and some are just "dear God what the fuck is wrong with us"
Don't judge too harshly. I KNOW you have some weird works stored somewhere.

“You want to play a game, right?” he asks, and something about the way his voice has canted low has you clenching your thighs.
“I do love games,” you tell him with a nod.

Summary
You weren't quite sure how it happened. New York City was known for crazy encounters and conspiracy theories, of course, and with the rather exciting -- to put it mildly -- event of actual aliens invading the earth about a month ago, you were sure nothing much could surprise you.
You were proven wrong when your small dog followed his nose to the end of the apartment complex's side yard.
After all, who would have thought New York had giant mutant turtles to befriend?
Series

Summary
“Sorry, (Y/N). I gotta bounce.”
“What? We’re only halfway through the movie! What’s so important?”
“I promise, I wish I could tell you, but I’ll refund you for your ticket next time I see you. Just stay here and enjoy it on your own.”
“Casey Jones, don’t you dare leave-.”
“Sorry again. Bye!”

Okay I remember reading this a while ago and for some reason I've remembered parts of it (beach day, stuck in space) and I've spent TWO DAYS looking for it.
