AN: Klaine will always be endgame for me, but every now and then I can't stop myself from shipping Kurt with other characters. A few weeks ago, I went through a major Kurtbastian/Sekurt phase and I know that the only way to get over it is to write a fic about them. The idea for this one came to me one Saturday morning when I was wondering what would it be like if Kurt was the one who cheated on Blaine. I hope you guys like this story :)

By the way, I do not own Glee.

Love, Geri

Mine, Yours

-Chapter 1-

The sun had just risen when Sebastian stirred up and crawled out from underneath the countless sheets haphazardly piled on top of him. He sat on the left side of the bed and leaned against the headboard, rubbing his eyes to clear his vision. He yawned as he turned his head to glance at the clock sitting on his dresser which told him the time was 6:07 am. It was set to ring about an hour later.

Suddenly, his right arm searched the other side of the bed and he slowly and gently pulled away the sheets until the profile of another boy was revealed. His back was turned from Sebastian. He had beautiful brown wavy hair highlighted with strawberry blonde tips, his skin was a porcelain white which seems flawless from the lower back side until the shoulder where purple bruises were visible. And at the crook of his neck, a bite mark was obvious despite the dim light. Sebastian couldn't help but smile at the thought of where the marks came from, and he knew the other boy was going to be furious once he finds out they existed, but the Warbler couldn't even bring himself to care.

Sebastian scoots closer to the body and possessively wraps and arm around the other boy's waist. Then he graces the soft skin on the cheeks and behind the ear with gentle kisses. His lips just ghosting on the flesh and and every now and then he'd whisper, "Wake up. Wake up, please, Kurt." After five minutes or so of doing this, the brunette finally stirred. He turns around to meet Sebastian's gaze, completely locking his eyes on his. The Warbler was mezmerized at the beautiful hues of gray, blue, and brown harmonizing with each other. "Good morning," he said in a low voice.

"Good morning, Bas." Kurt replies, leaning up to capture his lips in a soft lingering kiss. When Sebastian pulls away, Kurt curls to his side and rests his head on his shoulder. Instinctively, the other boy wraps his arms around him as if he was going to fall if he let go.

"Why're you up so early?" Kurt murmurs against Sebastian's neck

"I don't know," replies Sebastian. "I just am."

"I'm glad you are," Kurt says, propping himself up on his elbow. "I love being woken up by your kisses." At these words, Sebastian felt like a cage of butterflies were released in his stomach. The smile which he didn't realize formed on his face shows nothing but happiness. Pure, sincere happiness. God, the things Kurt made him feel seemed like something that would be near as impossible for him to experience a month ago. But now they were there. At that moment. Together.

Sebastian leans in and presses his lips on Kurt's. Gentle like the first ones he's given him earlier, but Kurt presses harder on him and intensifies the kiss. Sebastian is caught by surprise but then he regains himself. Kurt's elbow gives in on him and he's lying flat on the mattress. Sebastian shifts his weight on top of Kurt's chest and his lips trail down from his mouth to his jawline, and finally to the crook of his neck. Sebastian gently nibbles on the flesh which makes Kurt's breath hitch, and when his teeth accidentally scrapes one of the bruises, Kurt hisses in pain.

Sebastian stops immediatly and pulls himself up. "I-I'm sorry," he stammers, sitting upright on his side of the bed, looking guilty and awful. Kurt soon follows him and rubs his back coaxingly "It's okay, Bas." he says.

"No, it's not. You t-told me to be careful..." Sebastian reasons out. Kurt looks at him with a confused expression, "You told me not to mark you. Well...your back. It's full of them."

Kurt reaches over his shoulder and runs his fingers through his back. What Sebastian said was true. It was full of bruises. And when he feels his skin on the neck, he could trace the bite mark. His eyes immediately shoots wide in worry and horror. Then he remembers what happened last night, when he and Sebastian could barely control themselves. "No," Kurt manages to utter a few words despite the fear that is now creeping into him, "It's okay, Seb. You didn't mean it." He turns to Sebastian and gives him a fleeting kiss on the cheek, "But I have to go," he says, getting up from the bed. He begins to put on his clothes which were rumpled from spending the night on the floor and tries to coif his hair up.

"Why are you leaving so early?" Kurt hadn't realized that Sebastian was already behind him. The Warbler wraps both of his arms around Kurt's waist and rests his head on his shoulder.

Kurt sighs and holds onto the arms around him. He debates whether to tell Sebastian a lie or the truth, but he was too discombobulated to make up a reasonable excuse so he hesitates, but then he says, "I need to get home because I'll have to get ready for lunch with Blaine."

Sebastian's hold loosens a bit. "What about...what about the bruises?"

"I guess I'll have to experiment with some make up later." Kurt replies.

"Oh" was the only thing that escapes the Warbler's mouth this time. He removes his arms and puts them on his waist. Kurt turns around and meets Sebastian's disappointed expression. He sighs exasperatedly and when he's about to say a word from a speech he's prepared if ever this moment dawned upon them, he is cut off by Sebastian smashing his hungry lips against his. Kurt gasps in surprise but he recovers, responsing to the sudden aggression. Kurt parts his lips as Sebastian forces his toungue into his mouth. They duel for dominance for minutes, teeth clashing, then finally Sebastian pulls away and puts their foreheads together.

"Have fun, Hummel." he says in a low voice, stealing another quick peck on the lips as Kurt was still trying to catch his breath. Sebastian walks back to his bed and climbs under the sheets before turning his back on Kurt. Kurt only stared in disbelief but took this as a sign that he should go.

As the door clicked shut, Sebastian curled up into a ball on his bed. He didn't even realize he was crying until he felt his pillow getting damp. Whatever happiness that was in him that morning was lost because reality had slapped him in the face like an ice-cold slushy. It was all fake. Kurt didn't like him. He was just using him. Just like everybody else in the past did. He winced at the memory of Kurt saying Blaine's name. Why couldn't he just break up with him already and be with him? Then everything would be simple.

Unfortunately, he was Sebastian Smythe. Nothing was simple in his world.
