[Some sexual stuff is still going down… again. This one does contain some plot too, but it's mostly fluff if you want to skip.]

The next morning, Kurt woke up alone in his bed. Confused, he glanced over at the empty space beside him. Blaine had definitely been there when they fell asleep in a sweaty, exhausted mess after a long, torturously slow round three late last night. Just like the previous two rounds, it had been absolutely mind-blowing. In just one night, Blaine had managed to become so attuned to Kurt's body, it had felt like they had been lovers forever. Blaine had been so responsive, it had been easy for Kurt to figure out what he liked. Just like their duets, being completely in sync had been almost effortless.

Which was why Kurt thought Blaine would have stayed. Kurt knew he hadn't explicitly issued an invitation to stay overnight, but he'd thought it went without saying that Blaine didn't need to leave.

Rubbing the sleep out of his eyes, Kurt rolled his head to look at the clock. 10:19 AM. Still early enough that if he called Blaine now, Blaine could come back and snuggle with him in bed. Maybe they could take a nap together.

Kurt was about to pick up his phone to call Blaine and whine about being abandoned when he caught sight of Blaine's clothes from last night, still neatly folded on the desk. Kurt glanced over to the chair, where he'd sleepily left a set of towels for Blaine last night, because no matter how tired and sexually satisfied he was, Kurt was always a polite host. The towels were gone, but Kurt didn't hear the water running in the bathroom.

Curious where Blaine was, Kurt skipped his usual Saturday morning ritual of lazily lying in bed and got up. After a quick trip to the bathroom, he headed for the kitchen, where he heard movement… and found Blaine, singing quietly to himself and swaying his hips while he cut fruit at the counter.

Kurt shuffled further into the room, and Blaine's head turned toward the noise. His face lit up when he saw Kurt. "You're awake!" He kissed Kurt quickly in greeting, then pulled back and picked up the song where he had left off, now at a louder volume. He grabbed Kurt's hands and danced him across the kitchen in time with his rendition of "For Once In My Life" by Frank Sinatra.

Blaine finished as they reached the table, and Kurt dropped into a chair. "Oh, no. You're a morning person," he moaned as Blaine shimmied back to the counter, apparently doing a Sinatra medley, for he'd switched to "Almost Like Being In Love."

Blaine just grinned and went back to cutting fruit while singing. Kurt got up to make himself a cup of coffee, then watched in amusement as Blaine continued swaying around the kitchen, transitioning to "Fly Me to the Moon," completely at ease in Kurt's kitchen.

By the time he'd worked his way through "I've Got the World On a String," Kurt had finished enough coffee to finally feel awake. When Blaine switched into "You Make Me Feel So Young," Kurt joined in. Blaine's face lit up in delight. He dropped the fruit in a bowl, rinsed off his hands, and pulled Kurt into his arms. They twirled and swayed across the kitchen and living room. As they hit the last note, Kurt steered them toward the couch and pushed Blaine down, falling on top of him and immediately capturing his mouth in a kiss.

It wasn't until a few minutes later, when Kurt was sliding his hands underneath Blaine's clothing, that he noticed what Blaine was wearing. "Where'd you get this?" he asked between kisses, tugging at the loose T-shirt and elastic waistband of Blaine's athletic shorts.

"My bag," Blaine replied, running his hands under the loose waistband of Kurt's pants and cupping his ass. "I figured there was a chance I'd get up before you and want to get in a run."

Kurt pushed up off Blaine and stared down at him. "You already went for a run? How long have you been up?"

Blaine waggled his eyebrows lasciviously and rubbed his erect penis along Kurt's through their clothing. "Around you, I always seem to be up."

Kurt couldn't contain his laughter. He collapsed forward onto Blaine, burying his face against Blaine's shoulder. Beneath him, he could feel Blaine's entire body shaking as he chuckled. "That was bad," Kurt said between giggles.

"So bad," Blaine agreed, his laughter slowing. More soberly, he added, "But you're stuck with me now, boyfriend."

Kurt smiled and turned his head to kiss Blaine's cheek. "Why did I ever agree to that?" he teased.

Blaine's hands were still resting on Kurt's ass, and he squeezed lightly as he slowly rocked his hips against Kurt's. "Because of that?" he asked huskily.

Kurt's breath hitched slightly at Blaine's movement. "I… ah, think it was more than that," he murmured.

Blaine tugged gently on Kurt's shirt, and Kurt sat up so that Blaine could pull it over his head. Blaine took advantage of the shift in Kurt's position to push him onto his back and lower himself down on top of Kurt. Rocking his hips again, Blaine dragged his hands up Kurt's sides and sucked on a spot on Kurt's collarbone. "How about that?" he whispered, his teeth grazing Kurt's skin.

Kurt hummed in contentment. "Maybe," he hedged.

Blaine sighed in mock frustration, his breath tickling Kurt's throat as he moved to plant a kiss just below Kurt's ear. He slid his hands down Kurt's back. As he moved his head and bit gently on Kurt's earlobe, he slipped one hand between them to grasp Kurt's penis. With one finger of the other hand, he gently circled Kurt's entrance. The combination of sensations had Kurt moaning loudly. He pumped his hips into Blaine's hand, and Blaine tightened his grip and ran his thumb over the head of Kurt's penis. "How about that?" Blaine hummed into Kurt's ear.

"Oh, God, yes," Kurt groaned, not even remembering what question he was answering. All he knew was that he wanted Blaine to keep going. Blaine obliged, moving his hand up and down Kurt's shaft with just enough pressure to keep Kurt on edge.

"You don't happen to have any lube in here, do you?" Blaine asked as he moved his other hand around to cup Kurt's balls.

"In my living room?" Kurt asked sardonically.

Blaine made a noise of disapproval and let go of Kurt's penis. Kurt made a noise of protest. "Don't worry. I'm coming back," Blaine soothed. He spit on his hand and slid it back into Kurt's pants, his wet hand now gliding more smoothly along Kurt's length. Kurt gasped and lifted his hips to push further into Blaine's fist, increasing the pace. Blaine followed Kurt's unspoken instructions and began pumping faster, then trailed his lips down to leave a wet path along Kurt's chest. When he closed his mouth around Kurt's nipple and flicked the tip with his tongue, Kurt lost it, coming all over his bare stomach.

Blaine stretched up to kiss him, and Kurt wrapped his arms around Blaine's neck and plunged his tongue into Blaine's mouth. Blaine shifted so he was straddling Kurt's thigh and began rubbing against it as they made out, making desperate noises in his throat that didn't immediately register in Kurt's post-orgasmic haze. As soon as he realized, he pushed Blaine off him and slid off the couch. Kneeling between Blaine's legs, he slid Blaine's shorts and boxers down enough to release Blaine's cock. After licking his lips hungrily, he surged forward and closed his mouth around it. He swirled his tongue around Blaine's penis, then worked up the shaft, tasting the precum that had collected on the tip. Blaine moaned and slid his fingers into Kurt's hair. Kurt slid his lips back down the length of Blaine's cock, then began to suck. Blaine's moan was louder this time. Kurt wrapped one hand around the base of Blaine's penis, squeezing gently, before repeating the movement with his mouth. Blaine kept moaning as Kurt increased his speed and tightened his grip. It wasn't long before Blaine was coming too, groaning Kurt's name as Kurt swallowed.

Kurt repositioned Blaine's shorts, then sat back on his heels and pressed a series of soft kisses to the inside of Blaine's thigh. Blaine tugged lightly on his hair, and Kurt took the hint and stood. He leaned over Blaine and pressed a long, lingering kiss to his mouth. Then he straightened. "I'm going to go clean up, and then we should have some breakfast."

"I was going to make pancakes," Blaine replied, turning his head to follow Kurt's movement toward the bathroom.

"That sounds delicious, but I don't think I have any milk. Or eggs, actually."

"You do now. I picked them up at the grocery store on my way back from my run."

"Seriously, what time did you wake up this morning?" Kurt called from the bathroom as he cleaned himself off.

"Not that early. 8:15."

"That's not possible," Kurt said as reentered the kitchen, where Blaine was pulling batter out of the fridge. "That time doesn't exist on weekends."

Blaine laughed. "Just because you've never seen it doesn't mean it doesn't exist."

"I'm pretty sure it does. Isn't that how we know Santa's not real?"

"Santa's not real?!" Blaine gasped, and Kurt nudged him playfully as he reached into a cabinet. He pulled out his electric griddle, a Black Friday bargain he didn't use nearly often enough. While Blaine poured the batter, Kurt found a spatula. After passing it off to Blaine, he began to set the table. He grabbed a spoon for the fruit salad Blaine had made, clearly additional grocery store purchases, since Kurt knew he hadn't had any fruit other than a few rotting bananas he was saving for banana bread. They worked in comfortable silence for a few minutes, and Kurt was struck with a sense of rightness, like having Blaine in his kitchen, enjoying a domestic Saturday morning together, was exactly how things were supposed to be.

The sense of rightness didn't fade as they discussed their plans for the day over breakfast. Despite Blaine's suggestive comments and begging eyes, Kurt insisted they leave the apartment, at least for a little while. Then Blaine grabbed the paper, apparently the only other person besides Rachel in their generation who regularly read it in print, and skimmed through it while Kurt checked on some watched items on eBay on his phone. After they cleaned up their breakfast dishes, Blaine grabbed a change of clothing from his messenger bag, causing Kurt to raise his eyebrows in surprise. "A little presumptuous, weren't you? Running clothes, a change of clothes, a toothbrush last night…?"

Blaine shrugged. "I figured it couldn't hurt to be prepared. Just in case. Not that I was assuming. Just hoping."

"Mhm," Kurt replied skeptically.

"What?" Blaine asked defensively.

"Nothing," Kurt said, because as comfortable as he was around Blaine, he still was a fairly reserved person, and blurting out how utterly charmed he was by everything about Blaine and how scarily strong his feelings were becoming was a little much for Kurt. "I'm going to take a shower. Can you amuse yourself for a little?"

Blaine nodded, and Kurt headed down the hall to his room. Thirty minutes later, he emerged from his room to find Blaine, fully dressed and sitting at Rachel's old rehearsal piano that she'd finally convinced her dads to bring from Ohio to New York a few years ago. Blaine was completely absorbed in the notes he was playing and the words he was pausing to scribble in a small notebook, totally oblivious to Kurt's presence. Recognizing the look of someone who was creatively in the zone, Kurt settled into the couch with a magazine and waited, sneaking occasional glances at his sexy boyfriend. (Boyfriend! his brain repeated.)

Almost an hour later, Blaine looked up and caught sight of Kurt. He looked over at the clock and smiled sheepishly. "I'm going to guess you've been there a while."

Kurt nodded. "It's okay, though. I get it. Sometimes you just get lost in the creative process."

Blaine smiled in agreement as he swung to face Kurt more fully. "Yeah, but still, that was rude of me. Sorry. I just… had a lot of feelings, and I had to write them."

Kurt set the magazine on the table. "You really don't have to apologize. If you want to stay and keep going, I've got other magazines I've been putting off for a while."

"No, no, I could use a break. Let's go." He slid the notebook back into his messenger bag, then held out his hand. Kurt slid his hand into Blaine's, then grabbed his keys and led them out of the apartment.

After spending several hours window shopping and exploring the galleries of Bushwick, as well as a stop by Kurt's favorite local sushi restaurant for lunch, they made their way back to the apartment. Rachel was home, so the three of them cooked dinner together while running through a medley of their favorite Broadway hits. After dinner, they opened a bottle of wine, popped a bag of popcorn, and settled in to watch Rachel's collection of Sex and the City DVDs. Just after midnight, Rachel looked at Kurt and winked, then wished them both goodnight in a suggestive tone.

"She's not very subtle, is she?" Blaine laughed from his spot in Kurt's arms.

"If you thought that was bad, just wait until you leave tomorrow. She'll just stare at me and say, 'So…' with this knowing smile until I give her enough information to satisfy her."

Blaine tucked his head more tightly into Kurt's chest. "I don't want to leave tomorrow. Can't the weekend last forever?" he whined.

Kurt tightened his arms. "I know. But we still have tonight…"

"Well, then, Mr. Hummel," Blaine said, standing and holding out his hand, "shall we?"

Kurt grinned and let Blaine pull him up and down the hall. "But we have to be quiet!" Kurt ordered as he followed Blaine into his room and shut the door.

"I can if you can," Blaine said with a smirk after he sucked on Kurt's neck, eliciting a loud moan.

"Oh yeah?" Kurt pushed his boyfriend back onto the bed and proceeded to use all the tricks he'd learned to drive Blaine wild, and Blaine happily reciprocated - which meant neither of them were very quiet. Kurt just hoped Rachel had some earplugs.
