Lily and James despised each other. Half true.
Lily and James were kind of friends. True.
Lily and James had sexual tension matched by no other. Very true.
Lily and James were as bad as each other. Completely true.
Their relationship started in reverse. They hated each other before they liked each other. They fought before they spoke. They were Evans and Potter before they were Lily and James.
"Evans, you have weirdly nice eyes" Lily snorted at James' 'compliment'.
"You know Potter, that would have sounded a whole lot nicer if you didn't hiccup at the end" she swung her legs onto his lap, reclining against the sofa with a bottle of Firewhisky in her hands, sloshing onto the floor.
He frowned, creases appearing in between his eyebrows "Potter" he scoffed "why can't you just call me James?" She looked at him blankly and snorted again.
"Because you're Potter, Potter. James is dangerous territory." He grabbed the bottle back.
"Dangerous territory my arse, James is a perfectly good name. And you've drunk all my Firewhisky you bloody lush"
"Says you, you're as wankered as I am, besides it can be your present to me"
"As if you deserve any presents, if anything I deserve presents" he said, moving so his head rested on her lap.
"My company is your present, you lucky fucker" she looked down at him with what can only be described as the drunkest grin and they both burst out laughing.
The clock in the common room chimed midnight, the fire died a bit more and James and Lily laid on the sofa together completely. Somehow James' arm was draped lazily around Lily's waist and her leg was flung haphazardly over James'. So close their noses were almost touching and James could smell the alcohol on her breath.
"I guess I'll take you as my present" he whispered.
"Wow James do you want to me a bit more cheesy" she laughed.
"You're such a bitch Lily Evans" he scowled at her, pulling away as far as he could, but wasn't able to completely hide his grin
"Yeah" she yawned "but I'm a good shag, so you'll keep me around" she winked and then snuggled closer.
"Well there is that," he sighed, a stupid smile on his face "I guess we really should tell everyone we're going out at some point, or are you too ashamed?"
"Definitely too ashamed" she mumbled into his jumper "but I like you, and you're a good shag too and you bring me Firewhisky but now I need to sleep." She planted a clumsy kiss on the bottom of his chin, the only part she could reach, before she completely fell asleep on him.
"Hmm we'll tell 'em tomorrow" he said closing his eyes and pulling the blanket from the back of the sofa over them before kissing her freckled forehead and falling into a drunken sleep.
