Chapter 1

Warm lips and sharp teeth nip at the skin on his neck, mapping the path his shirt leaves with as each button comes undone hastily by strong, experience hands. His body trembles against the cool tile of the restroom wall as his shirt comes off and the exploring mouth finds his nipple.

A loud gasp leaves his body only to be met with the mischievous laughter of Sebastian Smythe. God how he hates that laugh and the cheeky little grin he can bet his life on that Sebastian is wearing right now. But what he hates the most is himself for allowing this, for giving his body to a boy who to him, is probably is just another number. Most of all he hates himself for doing this to Sam.

Sam Evans. The perfect boyfriend, his dream come true, the boy that not only stood up for him against bullies, but also besides him holding his hand in the crowded halls of McKinley. The one boy who is proud to be his boyfriend no matter what anyone says or thinks.

And this betrayal is eating at him slowly every day, but he can't stop himself. It's like he's addicted to Sebastian's body, to the taste of his lips, the feel of his hands holding his waist tight as he fucks him hard as if his life depended on it, to the feel of his warm seed spilling deep inside Kurt. And instead of being sated afterwards he just wants it more and more and it drives him crazy.

But it's so hard to think of Sam as his pants are being thrown to the side and Sebastian's fingers are opening him up, his legs wrapped around Sebastian's waist as the taller teen lifts him up and against the wall. The warm hurt that comes next is only momentary and followed immediately by the burning pleasure Sebastian is able to give him. It's hard and it's fast and he is cumming before he is even able to say something, with Sebastian's lips attached to his own, feeling the wonderful sting of Sebastian's release as the tall boy's orgasm follows.

Sebastian sets him down slowly, Kurt would say almost gently, with his forehead resting against Kurt's as they catch their breath. It seems so intimate that for a fleeting moment Kurt wants to lie to himself and think that there's more than just an animalistic attraction; that would at least help him validate whatever this is to himself and maybe ease his guilt. But as soon as the tall Warbler tucks himself in, any trace of tenderness that might of been there disappears to be replaced the arrogant and cocky grin that is Sebastian's trademark.

The lights flicker in the restroom, announcing the start of the competition. "A pleasure as always Princess, but it seems like it's time to teach your sorry public school asses a lesson and win Regionals," said Sebastian cheekily.

"It seems like your orgasm was better than I expected if all your blood hasn't made it back to your head yet that you are hallucinating now. Because only in your dreams would you be able to defeat us Sebastian," replied Kurt in a bored tone as he fixed his hair back into perfection.

His eyes met Sebastian's gaze through the mirror and for a split second he thought the Warbler was going to try to fuck him again when the restroom door opens and at the threshold stands Sam Evans, his boyfriend.

For a second all warmth left Kurt's body, fearing that Sam might of heard his loud needy moans from just moments ago; one look at his boyfriend's face through the mirror told him he had nothing to worry about.

"Sam, honey, what are you doing here?" asked Kurt with a fake calmness.

"They just announced first call and since it took you a bit too long, I came to see it you were ok," said his boyfriend, looking at him with eyes full of love that made Kurt's stomach twist. "Is this dude bugging you again? "asked Sam, nodding and glaring menacingly towards Sebastian who was standing just a few feet behind Kurt.

"Don't make me laugh Blondie! As if I waste my time harassing pretty little milkmaids when I can spend my time getting off with better prey. Now if you don't mind I need to get ready before I catch fire by sheer proximity to him," snidely interrupted Sebastian as he made his way towards the door only to find it block by Sam.

"I'm not moving till you apologize to my boyfriend for your comment just now," growled Sam, eyes ablaze with unnecessary rage.

Sebastian was about to make another offensive remark when Kurt took a hold of Sam's hand and pulled him away from the door, wrapping his arms around the blond teen's neck. "Don't mind him sweetie, he's probably hoping you'll hit so he'll have you disqualified. Totally not worth it," Kurt said, placing a soft hand on gently against Sam's cheek.

"But thank you so much for defending my honor my sweet man, my knight in shining armor," continued Kurt, giving Sam a kiss with each nickname. "Now let's hurry and go show those Warblers what we are made of. I'm dying to give you your reward for being so valiant," ended Kurt, kissing his boyfriend hard and passionate, the way he rarely does in public.

The pain in Kurt's chest intensifies as Sam rests his forehead against Kurt's in the exact same manner Sebastian had done only seconds ago. With a blinding smile Sam said "God I love you Kurt."

Faking a sweet smile, Kurt couldn't help but respond "I love you too" because he does. Kurt Hummel loves Sam Evans with all his heart and it's why it's killing him slowly every time he is with Sebastian. It makes him want to punch himself but hard as he tries his body always betrays him when the tall Warbler is within close proximity.

Kurt couldn't help but steal a glance at Sebastian as he walked out of the restroom hand in hand with Sam; if he didn't know any better he would've sworn he saw burning jealousy in the tall Warbler's green eyes for just a second. Shoving that thought down as soon as it appeared, he followed Sam to their seats, promising himself to ignore any thoughts of Sebastian that might cross his mind tonight.

S&K

Rough hands traveled from his chest up to his neck and caressed his cheek. "I love you so much," Sam panted huskily from under him.

Tilting his face down, his gaze met Sam's, letting the love, passion and desire that he found in those eyes fill him the same way Sam's member filled him now as he rode him, his hips swinging up and down slowly, lazily enjoying every trust and making it last.

Making love to Sam was always so different than having sex with Sebastian. With Sam it was always tender, sweet, loving but still passionate; they would always try to make it last longer and enjoy every second of it. With Sebastian, it was always fast, hard and dirty, leaving you satisfied but not fulfilled, always making you look forward to your next fix. It wasn't that Sam's body wasn't as addicting as Sebastian; he could never keep his hands off of either boy. He would always find himself satisfied and blissfully sated in Sam's arms afterward; you could even say fulfilled.

Sam wrapped his arms around Kurt, keeping himself sheathed in the brunette as he moved into a sitting position. Kurt wrapped his arms and legs around Sam's neck and waist, both of them rocking their hips and breathing together, faces buried in each other's necks as they exchange kisses sporadically till Kurt went silent and still as his orgasm overtook his body and erupted between their bodies. That soon followed Sam's seed exploding inside Kurt as the young brunette clenched around him.

"Thank you," Sam whispers, wrapping his arms around him and slowly pulling out of Kurt.

"If it's for the orgasm I should be the one thanking you sweetie," giggles Kurt as he gets comfortable in his boyfriend's arms.

"Well for that too, but mostly for making me so happy and always being there for me when we were standing on that stage tonight getting the trophy. I knew there wasn't anyone else I would rather be with and share this but you for the rest of my life."

"Mr. Evans, are you proposing?" whispers Kurt, turning so that he was eye to eye with Sam, their chests plush together.

Sam ran his fingertips slow from Kurt's hair down to his face. "No, not proposing, but making a promise that when we're both older and stable I will," the blond boy answered. "Would you? Accept if I was?"

"In the future... if you still want me I promise I'll accept," the constant ache that he'd had in his chest ever since he started sleeping with Sebastian intensified with the knowledge that he might never get that proposal once Sam discovers his deceit.

In that moment Kurt makes a silent oath to stop this thing with Sebastian, even if the need and desire kills him, and to do anything in his power to make sure Sam will never find out.
