Kurt and Blaine settle into living together pretty quickly for the most part. They were already used to spending so much time together, and Kurt is eager for all the Blaine time he could get before his boyfriend moves away at the end of the summer. Or, at least, almost all of the Blaine time he could get.

After the incident in Blaine's dorm room when Blaine tried to go a little farther than Kurt was comfortable with, Blaine has stuck to his word that he won't go any farther until Kurt is ready. Really, he has. Blaine has hinted at it plenty of times, sure. Whispers in Kurt's ear about how good it would feel to be inside him, about how much Blaine wants him, about how good Blaine wants to make him feel. Kurt's gotten pretty good at brushing the comments off, but he's had to reassure Blaine several times that it's not Blaine, it's him, so he still feels bad about it. He's getting closer, but he's still not quite there. Kurt knows that it's hurting Blaine, that Blaine is anxious and has been ready for months now and really, what is wrong with him? He has a beautiful boyfriend who wants nothing more than to make him feel good, and he's not ready? He tries to tell himself that it's okay, that there's nothing wrong with him setting a slower pace, but every time he sees that disappointed look in Blaine's eyes, he feels a pang of guilt and it chips away at those convictions a little bit more. And lately, they've been fooling around more often. They're teenage boys, after all, and they take full advantage of the opportunity when they have the house to themselves; and more and more frequently, Blaine is whispering those words into Kurt's ear, and Kurt is feeling awful when he turns Blaine down yet again.

Today is one such day that the boys have the house to themselves. Burt and Carole are away on a weekend trip with some of their friends, and Finn is out with Rachel for the day. Kurt is laying on his back on his bed, Blaine hovering over him, grinding into him and kissing him breathless.

Blaine pulls away from Kurt's lips, and Kurt whines at the loss until Blaine is reattaching himself to Kurt's neck, licking and sucking, and the whine turns into a moan.

"Blaine, oh my god," Kurt gasps, rolling his hips up into Blaine as Blaine moves down and sucks on the spot on Kurt's collar bone that he loves.

"I want to taste you," Blaine says into his skin.

"Blaine, please," Kurt whimpers.

Then Blaine is sitting up a bit higher, and tugging at the bottom of Kurt's shirt. Kurt helps Blaine pull the shirt over Kurt's head, and then Blaine is pulling his own shirt back off. Then his mouth is back on Kurt.

Blaine makes a slow trail down and across Kurt's chest with his mouth. He licks his way down to Kurt's right nipple, swirling his tongue around it, over it, and then blowing a cool breath of air on the skin and Kurt shivers as the small nub hardens. Blaine sucks it into his mouth, rolling it with his tongue, and Kurt lets out a low moan.

"Blaine," he gasps as Blaine pops off and trails his tongue across Kurt's chest, to the other nipple, giving it the same treatment as the first while he rolls the right one between his thumb and finger.

When Blaine finally seems satisfied with his work, he continues his way down Kurt's torso, sucking on the skin in the places he knows Kurt is most sensitive, until he reaches Kurt's belt and slowly undoes the buckle. By this point Kurt is writhing around on the bed, desperate and begging for it.

"Please, Blaine, oh my god, please."

"Please what, love?" Blaine asks with a smirk as he undoes Kurt's zipper and tugs the jeans and underwear down, Kurt's hard cock springing free.

Blaine loves playing this game, and if Kurt is being honest, he kind of likes it too. Blaine likes to hear him talk dirty, and Kurt has a hard time with that a lot of the time, but when Blaine has him like this, he will say anything to get Blaine's mouth on him.

"I want you to suck me," Kurt gasps as Blaine wraps his hand around Kurt's throbbing dick and slowly, lazily begins to stroke him.

"You want me to suck you, hm? Where? Here?" Blaine asks playfully, smirking, and then leans down and sucks at a spot on the inside of Kurt's thigh.

Kurt moans, takes in a shaky breath, shakes his head.

"No? You don't want me to suck you?" Blaine asks, looking back at Kurt again, eyes twinkling with mischief.

"Suck my cock, please," Kurt begs, because at this point, he is not beyond begging. He needs this. "Please, Blaine, I want to feel your mouth on my cock, please, please."

"As you wish," Blaine says, and then he's sinking down around Kurt and even if Blaine could speak around the dick in his mouth, Kurt wouldn't have been able to tell you what he'd said.

Blaine bobs up and down on Kurt's cock, swirling his tongue around the head and sucking and Kurt is squirming beneath him, trying to stop his hips from thrusting deeper into Blaine's mouth. But then Blaine is taking him further, deeper than he ever has, and Kurt feels Blaine's nose in the patch of hair at the base of his cock, and he groans.

"Blaine, fuck, oh my god, yes," he gasps, breathless, head thrown back.

Blaine comes up, a loud pop when he releases Kurt from his lips, and he smirks. "I love it when you're like this," he says, voice raw from having taken Kurt so deep and why is that so hot?

Blaine ducks back down, running his tongue along the vein on the underside of Kurt's cock, sucking Kurt's balls lightly into his mouth, just teasing, and it's driving Kurt absolutely crazy.

"Please, Blaine," he manages to gasp, and really he thinks it's pretty impressive that he can manage to say anything in the state he's in right now.

Blaine climbs up the bed, over Kurt, and kisses him fiercely, hand finding Kurt's cock and stroking slowly as Kurt moans into the kiss. Then Blaine is at Kurt's ear, whispering.

"I want you to come with me inside you. I want to feel your ass around me when I make you come."

Kurt moans. That does sound hot. In the back of his mind, he knows he still isn't really ready, but this does feel good, and Blaine really wants it, and really his boyfriend has done so much for him, and been so patient, and doesn't he owe Blaine this?

Before he can think too much about it and change his mind, he's nodding. "Okay."

"Okay, what?" Blaine growls into Kurt's ear. "I want to hear you ask for it."

"Please fuck me?" Kurt asks, and the words don't feel quite right coming from his lips, but he doesn't say anything else.

Blaine pulls back, and he can see the hunger in Blaine's eyes, and he thinks that maybe this really isn't so bad. Maybe he just needs to do it, and once he has, he'll be wondering why he waited so long. Blaine wants this, and he wants to make his boyfriend happy, and this will make Blaine happy.

"I thought you'd never ask," Blaine says, and then he's climbing back down the bed. "Turn over, on your hands and knees," he instructs, and Kurt complies, rolling onto his stomach then getting up on hands and knees, ass out toward Blaine.

Blaine puts his hands on Kurt's ass and spreads his cheeks apart, holding them like that. Kurt's starting to feel a bit self conscious in this position, everything out in the open for Blaine to see, but then he feels a soft breath, and then he feels something warm and wet, and oh god that's Blaine's tongue tracing around his hole. Kurt's head drops to the pillow under him as he groans, and he swears he can feel Blaine's smile against his skin.

"Mmm, you like that, love?" Blaine asks, teasing.

"Yeah," Kurt gasps.

"You want more?"

"Mhmm," and that's all it takes because then Blaine isn't talking anymore, his mouth is on Kurt, tongue teasing at his hole, pushing in slowly, and Kurt gasps again.

This goes on for a while, Blaine thrusting his tongue in and out of Kurt, Kurt wriggling beneath him and whimpering, until Blaine brings his mouth away and Kurt whines.

"I want to try a finger now... is that okay?" Blaine asks.

They've gotten this far; Blaine tongue has already been inside him, so he can't really change his mind now, can he? "Yeah. Yeah, do it," Kurt agrees.

"It might be a little cold at first," Blaine warns, and then there's a finger at his entrance, cold and wet, and Kurt realizes that must be lube and he's not sure when or where Blaine got that but he also doesn't really care at the moment because oh my god Blaine's finger is in his ass, and he's clenching around it, trying to get used to the feeling. It's a bit uncomfortable, not painful, but just... different.

"Shh, it's okay, love. Just relax for me," Blaine soothes.

Kurt tries to relax his muscles, and eventually he must succeed, because he feels Blaine slowly beginning to thrust his finger in and out, his mouth coming back down to tease at Kurt's entrance. Eventually the discomfort fades, and he gives into the pleasure, letting out low moans as Blaine thrusts his finger in faster and deeper. Then the thrusts stop, and he can feel Blaine's finger moving inside him, and it's not uncomfortable but just sort of odd, until he's overcome with a wave of pleasure like he's never felt, and something between a high-pitched moan and a gasp is coming out of his mouth.

"Blaine, fuck, fuck, oh my god," he's panting, and Blaine does it again and he's pushing himself back onto Blaine's finger, chasing the feeling.

"I think you're ready for two," Blaine says, and Kurt can hear the smirk in his voice.

Kurt feels the finger slip out and his hole clenches around nothing. But soon it's replaced, and Kurt feels the finger back, pushing into him, cold again with what must be more lube, and this time there's a second, and they're stretching him wider, and it hurts, just a little. He whimpers into the pillow, biting his lip.

"It's okay love, I have you. Just relax," Blaine soothes, and then Kurt feels a hand wrap around his cock and begin to stroke him slowly, and his whimper turns into a low, soft moan.

"That's right baby, I'm going to make you feel so good," Blaine says to him, and Kurt feels the fingers push further into him, slowly but surely, and the stretch is still a little painful, but the hand on his cock feels so good and he tries to focus on that feeling instead.

Eventually Blaine's fingers are completely inside Kurt, and Blaine stills them. He continues pumping Kurt's cock as Kurt gets used to the new feeling of fullness in his ass.

"You okay?" Blaine asks quietly.

"Yeah," Kurt replies, a little breathless. "Yeah, you can move now.

The pain is mostly gone now, he can still feel the stretch but it's discomfort than hurt. Blaine doesn't say anything, just slowly begins to pull his fingers out, and then thrust them back in, keeping pace with his hand on Kurt's cock, and the discomfort starts to ease. As Kurt begins to relax into the feeling, Blaine starts scissoring his fingers, stretching Kurt open further, and it stings a little, but it feels good, too, and Kurt's starting to think this might not be so bad. Every few thrusts Blaine pauses, crooks his fingers, and brushes against Kurt's prostate again, sending a jolt of pleasure through him, and that is certainly not so bad.

"I'm going to try another now," Blaine says, voice low.

Blaine's fingers slip out of Kurt's ass, and after a moment they're pushing back in, three this time, and it hurts but Kurt knows to expect it now. He bites his lip again, trying to hold in the whimpers, though a few escape. Blaine pauses when his fingers are fully inside Kurt, giving Kurt a chance to get used to the feeling, and he places a gentle kiss on Kurt's hip.

"You're so good for me, love. So hot like this."

He doesn't wait for Kurt's go ahead this time; he must have felt Kurt relax into the feeling, because then he's slowly thrusting into Kurt, matching pace with his hand on Kurt's cock again, spreading Kurt open as Kurt whines and squirms beneath him. Blaine places kisses along Kurt's hips, lower back, ass, as he works his fingers in and out of the tight hole.

"So perfect," Blaine whispers into Kurt's skin as he places another kiss on Kurt's hip. "Taking my fingers in your ass like this, moaning and whining and squirming. All from just my hand. Fuck, Kurt, you're so hot."

This goes on for a while longer, Blaine gradually increasing his pace, stroking over Kurt's prostate every several thrusts and sending a jolt of please through him. Eventually, Blaine speaks again.

"Do you think you're ready, love?" he asks into the skin of Kurt's hip, placing another gentle kiss there.

Kurt sucks in a breath, turns his head to look down at Blaine looking back up at him, eyes dark. "Yeah, I think so."

And then the fingers are sliding out of Kurt, and he whines at the loss. He hears Blaine rip the condom open, and then he feels his boyfriends cock against his entrance, teasing, then slowly pushing into him.

"Fuck," Blaine moans softly as he pushes deeper into Kurt.

Kurt thought the fingers stretched him wide, but Blaine feels huge. He bites his lip to fight back the whimpers, but he can't hold them all in. Blaine continues pushing in, slowly but surely, until finally his full length is deep inside Kurt.

"It's alright love, take your time to get used to it," Blaine soothes, leaning over Kurt and kissing his shoulder.

"It's just... a lot," Kurt says through gritted teeth.

"I know, sweetheart, I know."

Blaine reaches a hand around and grasps Kurt's cock again, setting a slow, soothing pace, and Kurt whines at the feeling. It feels good, and it helps to distract from the burn he feels as Blaine's cock stretches his hole open. Eventually, though, he does get used to the feeling of being so full, and he just wants Blaine to move.

"Blaine," Kurt whines, and if he'd thought it through, he'd know that wasn't doing to get him anywhere because he isn't actually asking for anything.

"Yes, love?" Blaine asks.

"Move," Kurt says, "please."

Blaine doesn't respond, just slowly pulls his hips back, sliding out of Kurt until he's barely inside him, and then thrusting back into him just as slowly, and the two boys moan together at the feeling.

"You feel so good, Kurt, fuck," Blaine gasps as he continues to thrust, picking up speed.

Kurt doesn't respond. As he gets used to the stretch, he starts to enjoy the feeling. Eventually he's all moans and gasps and whines at every thrust of Blaine's cock into his ass, every stroke of Blaine's hand over his own throbbing cock, every time Blaine bites into his shoulder, and he feels the pressure building in his balls, feels the release getting closer.

"I'm gonna... Blaine, I'm-" he gasps, breathless, unable to get the words out.

"Come for me, baby. I want to feel you," Blaine coaxes, thrusting into him faster and harder.

Blaine slams into him and swipes a thumb over the head of his cock on an upstroke, and that does Kurt in. He's coming hard, shooting across the bed sheets and moaning high-pitched, incoherent words as his ass clenches around Blaine's cock, riding out his orgasm. Blaine thrusts a few more times, and then he's moaning load, coming in Kurt's ass, then collapsing on top of Kurt.

The two of them lie there for a few minutes, recovering from their orgasms. Finally, Blaine rolls off of Kurt, sliding out of him, and he hisses at the sensation. He turns to face Blaine, whose smiling back at him warmly.

Blaine reaches out, brushes some hair out of Kurt's face. "That was amazing," he says, then leans forward and places a gentle kiss on Kurt's lips, pulls back, then, "You're amazing," and another kiss. "I told you I'd make it good for you. Bet you're wondering why you waited so long now," Blaine teases, but doesn't give Kurt a chance to answer, just kisses him again.

They lay in the bed a few moments longer, Blaine's arms wrapped around Kurt, until Blaine finally speaks again.

"We should probably get cleaned up," he says with a laugh. "We made a bit of a mess."

"Yeah, I guess you're right. I'm going to go take a shower," Kurt agrees, standing up off the bed and wincing slightly at the movement. He's going to feel this tomorrow. " Or maybe a hot bath," he amends.

Blaine laughs lightly. "A bath might be a good idea."

Kurt makes his way into the bathroom, locking the door behind him. He starts to run the bath, and as the tub adds some bubble bath and lays out a towel for himself. He feels... weird. It's not that he regrets what they've just done, necessarily. He can't deny that it felt good. But he'd thought, or at least hoped, that once it was over he'd feel like he made the right decision, and at this point he just isn't sure if he has.
