A smirk worked its way onto Blaine’s face as he entered his room with Sebastian following close behind. He took in his boyfriend lying curled up on his bed, Kurt looked perfect, even in his sleep.
Blaine quietly crawled into his bed, trying not to shift Kurt too much. He settled behind Kurt and began to remove the buttons of Kurt’s vest, silently cursing his boyfriend’s love of layers.
Sebastian kneeled on the edge of Blaine’s bed and began to unbutton Kurt’s jeans, sliding them down below his ass.
Blaine finally managed to slide Kurt’s vest off and began working on his shirt, leaving a trail of kisses from Kurt’s ear to his lips. Kurt let out a small moan but thankfully remained asleep.
Sebastian kissed along the waistband of Kurt’s boxers, slowly edging them down to expose his cock. As Blaine kissed Kurt on the lips Sebastian began to lick up the length of Kurt’s cock before sucking the head.
Blaine smirked as Kurt started to blink, his hands ghosting up and down Kurt’s chest.
“B-Blaine? Seb? What are—“ Kurt was cut off as he moaned, Sebastian had begun mouthing at his balls.
Blaine cupped Kurt’s face with his hand, kissing him before placing his hand on Kurt’s hip. Kurt slid a hand into Blaine’s hair, holding him closer before moving his other hand to Sebastian’s hair to keep him in place.
Sebastian licked up Kurt’s cock, moaning as he swallowed Kurt whole. Kurt thrust up into Sebastian’s mouth causing Sebastian to hold Kurt’s hips to the bed to keep Kurt from choking him.
Kurt tugged on Sebastian’s hair as he neared his orgasm, trying to give Sebastian some sort of signal. Sebastian pulled off with a pop, sliding up Kurt’s body to kiss his neck. He began to suck a hickey into Kurt’s neck while Blaine broke away.
Blaine reached for the nightstand, searching for the lube; he grabbed it with a triumphant cry and returned to Kurt and Sebastian. Kurt was moaning under Sebastian, struggling to keep himself from coming too early.
“Blaine… Sebastian… Please…” Kurt moaned, his eyes closing. Blaine smirked and squirted some lube onto his fingers, Kurt’s eyes shooting open at the noise. He warmed the lube between his fingers before reaching behind Kurt, tracing along his backside until he found his hole. Blaine began to trace around the puckered entrance, trying to loosen Kurt up.
Blaine kissed Kurt to distract him as he slipped the first finger inside to the knuckle. Kurt moaned, his grip on Sebastian’s hair tightening almost painfully.
Sebastian began to rub soothing circles into Kurt’s hipbone, trying to help Blaine distract Kurt from the sensations.
Blaine began to pump his finger in and out in an attempt to loosen Kurt. Slowly he worked his way up to his whole finger, steadily pumping it in and out until he could fit in a second one causing Kurt to moan into Blaine’s mouth.
Sebastian sat up, tugging on Blaine’s hair to pull him away from Kurt’s mouth, “That’s enough,” He murmured, “My turn now.” He said, kissing Kurt deeply.
Kurt continued to moan into Sebastian’s mouth, fisting both hands into Sebastian’s hair to keep himself grounded.
Blaine used this chance to add a third finger, causing Kurt to cry out and tear himself away from Sebastian, “I need you in me. Now.” He ordered.
Blaine smirked and removed his fingers, slicking up his cock with lube and lining himself up with Kurt’s hole. He slowly pressed in, kissing along Kurt’s neck as Sebastian used the opportunity to slip his tongue into Kurt’s mouth and battle for dominance.
Blaine groaned loudly when he bottomed out, resting his forehead against Kurt’s shoulder and stilling to allow Kurt time to adjust.
Kurt squirmed, trying to get Blaine to start moving, when that didn’t work he pulled away from Sebastian, “Please, please move.” He gasped, tangling a hand in Blaine’s hair.
Blaine nodded and pulled out, thrusting back in immediately. He built up a steady rhythm, pumping in and out of Kurt gradually gaining speed. Sebastian smirked at Blaine over Kurt’s shoulder. “Room for one more?” he asked, biting at Kurt’s neck and raising an eyebrow at Blaine.
Blaine smirked, “Kurt?” he asked, stilling momentarily.
Kurt nodded, “Yes. Just… now, please.” He gasped.
Sebastian smirked and slid in a finger next to Blaine’s cock. Blaine gasped, “He’s so tight, Seb. Can’t wait until you’re in here, too, it’s going to feel so great.” He cupped Sebastian’s neck and pulled him in for a kiss over Kurt’s shoulder.
Sebastian pressed a second finger in and scissored them, stretching Kurt as best he could. “Sebastian get inside me. Now.” Kurt hissed, pressing down on his fingers.
Sebastian pulled away from Blaine and scraped his teeth along Kurt’s neck, playfully biting down, “Yes, sir.” He said with a snort.
Sebastian removed his fingers and began to press his cock in, kissing Kurt’s neck as he did. Blaine pressed a kiss to Kurt’s lips and tried to distract him from the stretch.
Kurt moaned at the feel of both of them in him, “Both of you need to move or I’ll come right now.” He gasped.
Sebastian grinned at Blaine and started to thrust in and out of Kurt hard and fast, Blaine mimicking him at a much slower pace, dragging his cock in and out of Kurt’s ass slowly.
Kurt whimpered at the different sensations, feeling the familiar heat building in his groin. Kurt moaned and dropped his head against Blaine’s shoulder as he came.
Sebastian smirked and began to pound in and out of Kurt’s ass, going faster and faster as he neared his own orgasm. He quickly came and stilled inside of Kurt, waiting for Blaine to reach his release.
Blaine had waited until both of his lovers were finished before speeding up and coming, filling Kurt up even more.
Kurt groaned, he was going to be so sore tomorrow. Blaine grinned and started to pull out, kissing Kurt’s cheek and collapsing next to him on the bed.
Sebastian imitated him and rolled onto his side next to Kurt, wrapping his arms around him, “Did you like your birthday present, babe?” he asked as he started to catch his breath.
Kurt laughed tiredly, “Best birthday ever.” He muttered.
Blaine grinned, “Good, because I was kind of hoping you would both be willing to do something like that for my birthday.”
Kurt laughed and shoved at Blaine’s shoulder before pulling him close, “Okay, but cuddle time now.” He said, closing his eyes and curling up in between his lovers.
