Requested yet again by: Jersey(supernaturalfreakme) on Tumblr

Warnings: Smut, badboy!Kurt, top!Blaine(I know some people don't like it) otherwise read away!

I really hope that you all enjoy it. First time crack at badboy!Kurt, which is an idea I ran by Jersey, who approved! Those of you who have Tumblr, you should really check her blog out. She is really great and I love her! (:

"Will you just relax Blaine?" Kurt whispered coolly.

"What if someone walks in on us Kurt?" Blaine mumbled into the empty girls bathroom, looking around uncomfortably.

"We should really be at Glee Club." he assured.
"What if Rachel comes looking for us?" he continued and Kurt rolled his eyes, grabbing Blaine by his belt loops and pulling him forward.

"Now, why would you want to mention Rachel at a time like this." he frowned.
"Just be an exhibitionist Blaine? We can make it really quick." Kurt breathed against Blaine's ear, his warm breath making Blaine shiver, pressing Kurt up against the sink.

Kurt growled, growled; pressing his lips against Blaine's hungrily.

"I want you Blaine, I want your cock pounding into me right now. Make me scream your name Blaine, make me."

"Fuck, Kurt." Blaine whined, his fingers digging into the skin on Kurt's hips, from where his shirt had ridden up.

Kurt smirked cockily. "That's sort of what I was hoping for baby." he teased. His hand trailing down Blaine's chest, who's breath hitched as Kurt's fingers barely grazed over his hardened length that was straining in his tight skinny jeans.

"Where do you want me Blaine?" Kurt whispered seductively.
"Do you want to pound into me on the floor, Blaine? Or do you want to press me against the wall and fuck me there?" Kurt's fingers continued to tease around Blaine's clothed erection, which twitched under Kurt's touch and Kurt watched as his boyfriends lust filled eyes dilated and began to darken in want.

"Where do you want me Blaine?" Kurt asked again, his voice dropping dangerously.
"What do you want me to do?" he continued, popping the button to Blaine's pants open, his fingers playing with the rim of Blaine's boxers before he then pulled them down too. Blaine's erection springing free, he groaned; twisting his fingers in Kurt's hair and smashing their lips together in a sloppy, heated kiss, their teeth clacking together.

"I want you on the sink." he panted against Kurt's lips his fingers fumbling with the button on Kurt's jeans, before he finally pulled them down, his hands shaking.
"How do you want me on the sink?" Kurt questioned, his hand already trailing down to his hard cock, teasing it—and smirking as Blaine's eyes followed.

"Prop yourself up." Blaine demanded.
"I want to fuck you with your ass hanging off of the edge."

Kurt's eyes widened for a minute. Before he stepped back, propping his elbows on either side of the sink and then Blaine was there in a heartbeat, wrapping Kurt's legs around his neck.

"Blaine, fuck, please."
"Don't prep me, just fuck me don't hold back." Kurt begged.

So Blaine did just that, unable to wait any longer, lining his dick up to Kurt's hole and thrusting in Kurt's screams of pleasure shattering off of the girls bathroom wall as he immediately started rocking back against Blaine who's thrusts quickened.

The sound of skin slapping against skin echoing along with Kurt and Blaine's pants and groans, Blaine's fingers probably leaving bruises on Kurt's hips, where he held Kurt in place as he continued to pound his hips upward, the skin of his dick dragging in the warm tight heat while Kurt clenched around him, cumming with a shout.

"Kurt, Blaine—glad to see you can make it to Glee rehearsal considering your fifteen minutes late. While everyone else here was preparing for nationals yous both better have a likely excuse..." Rachel shrieked the minute they walked into the choir room doors.

"So sorry Rach, I wasn't allowed to leave class until I finished my uh-Anatomy test. That's the reason why I'm late." Blaine said quickly, dodging his sisters gaze, and rushing towards his usual seat a blush already making its way onto his face; attempting to once again fix his hair and clothes discretely.

"Kurt?" Rachel sneered, glaring at him slightly. "Your excuse."

Kurt rolled his eyes and opened his mouth to retort angrily but Mr. Schue interjected before he could get a word out edge wise. "Rachel, enough. Kurt go and take your seat."

"You got it Schue." Kurt responded, taking his seat next to Blaine, wincing slightly, which did not go unnoticed by Santana.

"I mean just wanky." Santana stated, leaning back in her chair.
"Hummel here is getting some."

"Santana," Mr. Schuester warned.

Puck's eyes shot up, glancing wearily at Kurt.
"Who knew Hummel would bottom!" he exclaimed in disbelief.
"I think I actually lost an ounce of respect for you dude. I thought you would be owning that ass over there."

"If you value any aspect of your sex life Puckerman I would just stop talking now if I were you. I'd hate to have an accident with my pocket knife." Kurt suggested with a raise of his eyebrows, as he examined his nails.

"Wait, Kurt... you are screwing Blaine?" Finn muttered.

Rolling his eyes, he sighed.

"As much as I enjoy telling my step brother about the intimate details of my sex life, at least get the fact straight that it's Blaine who fucks me." Kurt sighed, in disinterest; but deep down he was basking in it because in

BINGO

Rachel stood agape.
"Blaine, my baby brother. I'm sorry. No, there is no way my brother would stoop low enough to sleep with you." Rachel wouldn't believe it, she couldn't believe it, she refused to believe it.

She has not believed it since they started dating in the summer, and believe it or not—Kurt and Rachel used to be best friends that used to do everything together, her Blaine and Kurt grew up together, playing tea parties, having sleep overs. But when they got to high school everything started to change, sometimes she can't blame Kurt for turning out the way he did, with his mother dying, and the bullying he goes through with school. But when Blaine came out to Kurt, and he confided in Kurt, and started going out with Kurt... Rachel couldn't help to want me for her brother, so she pretends that their relationship with each other doesn't even exist.

But truth be told, Kurt is actually different around Blaine. Of course when they are fooling around or having sex, the dangerous Kurt comes out to play, but that is the way that he and Blaine like it. Blaine likes the way Kurt grinds him down, talks dirty, and lets him take control and his and Kurt's sex life could never be better. But when they are not having sex when Kurt is with Blaine he is at his calmest, and happiest state. He actually feels like he could live again. Blaine is his world, and Rachel just doesn't realize that, and that is why there is nothing that Kurt enjoys more than pissing his boyfriends sister off. She had been nothing but disapproving since the two of them got together.

Clicking his tongue ring against his teeth, Rachel winced.

"Really now Rachel? Because it didn't seem that way just a few minutes ago when we were fucking in the girls bathroom, isn't that right Blaine?" Kurt grinned, and if Blaine wasn't red before, he was now three shades deeper.

"Do you want a full detailed list of all the places your brother and I did it Rachel? I guess we should really leave out the one with your bed though. Oh whoopsie, I said that out loud didn't I? Well it looks like the cat is out of the bag now." Kurt gasped.

"I totally love cats!" Britney smiled, throwing her hands up in the air. Everyone shook their heads, and Santana looped their pinkies together, whispering into her ear.

"The dolphins are finally doing it now!" she exclaimed, getting up from her seat and plopping into Kurt's lap, who once again winced.
"I really hope my kissing lessons payed off Kurt. Did they pay off Dobby, did they?" Britney now questioned Blaine.

"Can I see if they worked Kurt, can I kiss you?"

Santana getting up from her seat, drug Britney off of Kurt's lap and back to her seat, clearly not pleased, while Blaine looked dumbly at Kurt as if asking what the hell just happened.

Kurt answered Blaine's question with a shrug.

"Alright, guys, seriously that's enough. We are done talking about this." Mr. Schue shouted, once again trying to settle the reins on the class, gathering their attention. But Rachel could not wipe that shocked, embarrassed expression on her face.

And that is why this was totally worth it... Kurt beamed, waving over at Rachel, with his free hand that wasn't holding Blaine's.
Just smile and wave Kurt, smile and wave.
