Blaine is jealous of Finn when he discover's Kurt had a thing for him...
Author's Notes: Originally on Tumblr taken from a prompt that read "Id love to read Blaine is jealous about Finn and Kurt living together in same house and Finn is Kurts former crush. like really really jealous, suspicious between them. and passionate sexy time.."
Blaine couldn’t take it; he knew it was wrong, he should trust Kurt but he couldn’t bring himself to be okay with the fact that Finn and Kurt live together. I know what you’re thinking; Finn is straight not to mention the fact that he is Kurt’s step-brother but Kurt had told him something the other day that had really made him change his opinion on Finn and Kurt’s relationship.
FLASHBACK
Kurt lay on his bed, legs propped up on the headboard and head hanging off the end, whilst reading the latest fashion magazine. Blaine was sat at Kurt’s desk, fumbling with various items that lay upon it until he stumbled upon a draw. In this draw lay a book with a blue velvet cover with the word’s ‘Kurt’s Diary’ on the front. Blaine grinned maliciously at his boyfriend before turning his attention back to the unopened book that now lay in his lap. He opened it, careful not to distract Kurt from his magazine, and started to read.
February 2009
Finn looked at me today instead of that troll, Rachel Berry, he even asked me for help in French but sadly he turned down my offer to tutor him this weekend at my house, oh well at least he is ignoring le hobbit for now...
March 2009
Finn is so cute in his football uniform even if it is the most unfashionable thing since Capri pants, oh how I wish I could kiss that face, the gullible but adorable face...
Entry after Entry, Month after Month went on and on about Finn and how handsome he is and plan’s to kiss him, complete with blueprints. Blaine could feel his fury rise and begin to boil; he flung the offending book across the room, hitting the wall with a bang. Kurt’s head flung up seeing a red, angry Blaine at one end of the room and his damaged diary at the other, Kurt could feel this wasn’t going anywhere good.
“Blainey, you okay?” Kurt asked sweetly, already guessing the answer.
“What the hell, Kurt, why didn’t you tell me you were in love with Finn!” Blaine yelled
Kurt sighed, he had feared this, “Blaine, first of all, calm down, your anger is frustrating and turning me on at the same time” He stated, allowing Blaine to take a few in takes of breaths before continuing.
“Yes, I did like Finn, not love him but I did crush on him, two years ago. You hear me, not now, two years ago” Kurt said calmly, getting up from his current position to kneel down in front of Blaine.
“I love you, not him, you” Kurt assured with a loving look.
But Blaine didn’t hear ‘I love you’ he only heard ‘I did like Finn’
END FLASHBACK
Now, Blaine was standing in Kurt’s living room watching from a distance as Kurt and Finn sit at a table studying French, something Kurt had repeatedly wanted to do with Finn as said in his diary. He watched on as they laughed when Finn said something wrong or asked an inappropriate question. They sat with inches between their faces as they burrowed their head in their work. Ever since the confrontation with Kurt about his previous crush, Blaine’s senses were on full alert. Every-time Finn helped Kurt with something or vies-versa he could feel his pit of rage seeping to the surface. When Finn’s hand brushed slightly over Kurt’s and they both looked up and giggled, that was breaking point for Blaine.
“That’s it!” He roared, storming up to Kurt and taking his hand dragging him up from the table.
“Blaine, I said I would be with you in-“Kurt began but was interrupted with a pair of lips on his, furiously attacking them with a needy and jealous incentive as he was being pushed up against a wall.
He soon reciprocated because Blaine lips always made him melt and want more; he latched one of his hands to Blaine’s face and the other one ran through his loosening curls. Blaine was determined to show Kurt that he was his so he swiped his tongue over Kurt’s bottom lip, pleading for entrance to which Kurt happily granted. The explosion of taste was phenomenal; a mixture of coffee and red-vines hit Kurt at a bullet-train pace and his knees went weak at the flavour. Kurt unexpectedly backed away and turned to Finn, Blaine pouted at this action and the feeling of jealously returned.
“You can leave now, Finn” Kurt announced as an awkward looking Finn shuffled out of the room, Blaine breathed a sigh of relief and Kurt turned to him.
“You were jealous again, weren’t you?” Kurt asked slyly, a breathless Blaine nodded. “Well jealously is a real turn on for me” Kurt said with a wink before turning on the balls of his feet towards the staircase.
“Where are you going?” Blaine asked with a deprived ring to his voice.
“Bedroom, we can get a lot more done up there” Kurt said seductively before darting up the staircase followed shortly by Blaine who muttered something that sounded suspiciously like ‘I should be jealous more often’
End Notes: This is my first attempt at writing a fanfiction so sorry if it sucked, I will keep writing if you guys like it!
