It was getting quite late when Blaine and Kurt bid Nick, Jeff, Thad and David goodbye as the four Warblers set off back to their dorms, leaving Blaine and Kurt in the senior common room. They had come over to Westerville for a catch up that turned into dinner that turned into their Warbler friends rubbing their eyes and excusing themselves off to bed.

Kurt finished his cup of decaf coffee, smacking his lips together contently and putting the cup on the table. He was about to suggest they head home when he saw something flash in the corner of his eye. Putting it down to tiredness, he stood up and walked over to where he had discarded his coat and bag.

And there it was again.

Kurt glanced around the room. There was no one there except for him and Blaine, who was busy recycling their cups by the Expresso machine.

And then Kurt saw him.

Sebastian.

He was lurking in the hallway, his beady little eyes glued to Blaine’s ass as the other boy finished up at the counter. Kurt wondered if he should call him out, let him know that he was aware of his creepy little stalker act. Or, he could have some fun with it.

Kurt wandered over to Blaine slowly, putting his hands on his shoulders and placing a wet kiss to Blaine’s exposed neck. Blaine’s eyes fell shut and he smiled widely.

“Kurt,” he said in a breathless voice. “Here?” One of the things he loved about Blaine was his ability to read his mind.

“Why not?” Kurt whispered against his ear. “We’re the only ones here and we’re not going to be disturbed.” His voice was low and despite how quiet he was, he was sure Sebastian was probably latching onto every word. If Sebastian didn’t feel threatened by Kurt, which he obviously didn’t by the continued pursue of Blaine, then Kurt was going to have to make himself a threat. Or at least show Sebastian that he didn’t have a chance in hell at getting Blaine.

He had tried everything from small hints like holding Blaine’s arm in front of him to straight out telling him to back off. Blaine had even deleted his number from his phone and blocked him on Facebook.

Sebastian needed to be told once and for all that Blaine Anderson belongs to Kurt.

Blaine turned around to face him. His lips were parted, his tongue running along the bottom of his top teeth slowly. His eyes were unblinking as he took in Kurt’s own desperate expression.

Kurt closed the gap between them, crushing his lips onto Blaine’s and throwing his arms around his neck so their bodies were flush together. Blaine, a little surprised by the action, let out a tiny whimper that turned into a deep moan when Kurt’s hands ran down his sides, resting on his ass.

Giving it a firm squeeze, Kurt detached his mouth from Blaine’s and he planted deliberate kisses along his boyfriend’s jaw line, stopping at his pulse spot where he began sucking hard. Blaine flexed his fingers in response, a faint sigh escaping his lips as he put his hands on Kurt’s hips. When Kurt started blowing cold air on his wet neck, Kurt felt Blaine’s knees buckle slightly.

“You like that?” Kurt asked in almost a growl. Blaine only whimpered in reply as he turned Blaine around, pushing him up against a nearby wall. Kurt’s eyes flickered over to where he knew Sebastian was watching and he caught his eye. Sebastian raised his eyebrows in response, licking his lips at Kurt who merely pursed his own and brought his attention back to Blaine.

Kurt returned to Blaine’s neck, kissing the smooth skin, nipping here and there. He pulled Blaine’s shirt free from his pants and ran his hands up the other boy’s stomach, his fingertips sending shivers down Blaine’s spine. He started to rub circles over Blaine’s nipples before pitching them hard; something Kurt had learnt early on drove Blaine crazy.

“Kurt,” Blaine gasped. He bowed his head forwards, almost hitting it on the wall in front of him.

Kurt’s hands started to descend as he popped open the button on Blaine’s pants, pushing them down so they rested at his ankles. Pulling his own pants down, Kurt thrust up against Blaine’s ass, feeling the friction only the feeling of cotton thin underwear against skin could cause.

Blaine gripped at nothing on the wall, a low broken moan giving Kurt the only ammunition he needed. He then pointedly locked eyes with Sebastian, a cocky grin plastered against his face as he noticed Sebastian’s blown eyes and lustful expression.

Keeping the gaze, Kurt reached around Blaine to take hold of his cock as he began roughly fisting him. Blaine reached over his shoulder to grip Kurt’s hair with one of his hands, his legs buckling again. Leaning forwards, Kurt licked up Blaine’s sweat covered neck, tasting a mixture of salt and vanilla, his eyes never leaving Sebastian’s.

“Who do you belong to?” Kurt asked gruffly, his tongue running a circle over Blaine’s pulse. He needed to hear Blaine say it out loud, needed to hear Sebastian hear it. Sebastian whose eyes were boring into his own, whose expression he couldn’t completely read, but knew that he was getting to him by how still the other boy was sitting, his lips pursed and his eyes unblinking.

“… what?” Blaine panted. He either didn’t hear Kurt’s question or was confused by the sudden possessive tone he had suddenly taken.

Kurt thrust up against Blaine’s ass again, this time harder than before. “I said.” Another thrust. “Who. Do. You. Belong. To?” With every word he spoke, Kurt thrust up, never breaking his gaze with Sebastian and never altering his hand’s rhythm.

“Y-you,” Blaine panted. “Only you. A-always you.” He pulled harder on Kurt’s hair, his face scrunched up tightly, and an almost pained look on his face.

Kurt suddenly spun him around to face him, crushing their lips together and pushing Blaine up against the wall. His hands took hold of Blaine’s hips and he pressed down, not caring that he’d probably be leaving bruises.

The kiss was hungry and full of too much teeth and tongue but Kurt didn’t care. He started grinding his hips against Blaine’s, feeling Blaine’s hard cock rubbing up against his own as he picked up the pace.

“I want to taste you,” Kurt whispered against Blaine’s ear, sending a bolt of pleasure straight to his own cock at Blaine’s expression. His eyes were completely blown so Kurt could no longer see the hazel in them and his mouth hung open, shallow breathing coming in deeply.

He pulled Blaine forward so that his back was to Sebastian, who Kurt didn’t want to give the pleasure of seeing the prize. There was no way he’d allow the other boy to see Blaine’s cock. Only he was granted that privilege. And with one final glance at Sebastian, who Kurt now noted now had his own hand in his pants and was fisting himself quickly, Kurt lifted down Blaine’s boxer-briefs just enough so that he could pull Blaine’s throbbing erection free.

“Say please,” Kurt said slowly, falling to his knees, his hands cupping Blaine’s balls, kneading them gently.

“P-please,” Blaine whined. His hands returned to Kurt’s hair, where he ran his fingers back and forth until he felt Kurt’s mouth engulf his cock. Blaine took a deep intake of breathe, clenching his fingers around a tuff of hair. “Oh, K-Kurt,” he said, his voice strained.

Kurt continued to work his balls as his tongue slid down Blaine’s cock, following the route of a rather large vein. He sucked hard on his head, licking his lips as he tasted pre-cum, salty and oh so Blaine.

“Fuck, so close,” Blaine muttered as he thrust himself further into Kurt’s mouth.

Taking hold of Blaine’s hips, Kurt started to hum, taking Blaine deeper until he was swallowing around the head of his cock. Blaine was beginning to shake now and it took all of Kurt’s strength to hold him still as Blaine’s orgasm took over and he was throwing his head back, shouting unrecognisable words at no one.

Kurt swallowed the last of the semen, wiping his mouth on his sleeve as he stood up, his hands never leaving Blaine’s body as he ran them up his side. Blaine was gulping air like he hadn’t breathed in years, blinking fast and often. He leaned forward to kiss Kurt, but it wasn’t like before. The kiss was passionate and soft, Blaine’s tongue running a line along Kurt’s swollen lips, urging for entry.

Opening his mouth, Kurt felt Blaine suck on his tongue and he wondered if he could take himself there. He only had a moment to ponder this before Blaine’s hand had shot into his briefs and started stroking him.

Kurt moaned against Blaine’s lips, allowing his eyes to flutter shut. Blaine’s mouth trailed down his neck and finally stopped at his collarbone, where he started to nibbler. Blaine’s hand increased its pace and it only took a few minutes before Kurt was thrusting his hips hard against Blaine’s hand, riding out his own orgasm, his face in the crook between Blaine’s neck and shoulder, filling his lungs completely before releasing the air in a low groan.

As Kurt came down, Blaine laughed, pressing their foreheads together. “Well that was -”

“- fun?” Kurt offered, smiling warmly at his boyfriend whose crooked smile still made the hairs on the back of his neck stand up.

“I was going to say ‘unexpected’, but yeah, fun works too,” Blaine finished, pulling his briefs on properly and pulling his pants back up. Kurt followed suit. When he was sure Blaine was preoccupied with his jacket, Kurt turned to where he knew Sebastian had been watching. The other boy was red faced, his expression a mixture of hunger and envy. His lip curled and his eyebrows were knitted together.

Kurt simply raised his own eyebrows, tilting his head to the side as a pasted smile told Sebastian that his games were over. He was never going to have Blaine and he better not try and contact either of them again.

“Hey, Kurt, are you ready?”

Kurt spun round, his expression softening as he accepted his bag from Blaine. “Yeah sure, let’s go.”
