Blaine is trying to respect Kurt's boundaries. Really, he is, even though Kurt hasn't actually laid down any. He doesn't need to say it; Blaine remembers his first boyfriend, knows that he should take this slow so that Kurt doesn't regret his first time. Especially given how they met.
But years of chivalry training haven't prepared him for the way Kurt looks at him sometimes, for the way Kurt presses his body into Blaine's when they kiss. He's profoundly unprepared for the curve of Kurt's lower back, for the way Kurt straddles his thighs, for the noises Kurt makes when Blaine sucks him off. It's been so long since Blaine had someone inside him and he's been finger-fucking himself every night for the last week to try to slake the lust. It hasn't worked and all he wants is to climb on top of Kurt and ride him until they both pass out, but he can't because gentlemen don't do that sort of thing.
Sometimes, he thinks Kurt does it on purpose, grinds up against him, wraps his arms around Blaine from behind. The few times they've fallen asleep together, he always wakes up with Kurt's erection pressing against his ass. He wouldn't mind at all if he could actually do something with it, but as it stands, it's just not fair. Blaine can't imagine what he did to earn this kind of karma, but it must've been horrible. The temptation is becoming unbearable and Blaine's honestly not sure how much longer he can last.
He finally loses it one night when Kurt is sucking him off, gripping Blaine's hip hard enough to leave marks and working him over so enthusiastically that his cheeks have gone concave. His thumb brushes against Blaine's balls, massaging gently, and then goes lower to that spot just behind them that drives Blaine wild. He arches his hips up off the bed, bucking out of Kurt's hold on them, and quite aside from nearly choking his boyfriend, the force of it makes Kurt's thumb slip lower, to push right up against his hole.
And Blaine just fucking loses it.
"Oh, God," he moans, and rocks against Kurt's thumb. He's at the wrong angle to force it inside him—wouldn't want it dry, anyway—but just the pressure is enough to rip at his already fraying edges.
"Blaine—" Kurt gasps, and Blaine can't take his eyes off of Kurt's mouth. His lips are slick and swollen, a deeper shade of red than they usually are. There's spit and pre-come dribbling down his chin, splashing onto his chest and continuing south. A drop of it falls from his lips all the way down to his cock, and Blaine's eyes follow it downward.
Kurt has one of the sexiest cocks Blaine's ever seen, and he has definitely seen his fair share considering that he's only seventeen. It's thicker than average, if a little bit shorter than Blaine's last boyfriend. Kurt gets hard so easily, even for a teenage boy. Blaine's never asked why, but he figures if he'd been as touch-starved as Kurt was for all those years, and suddenly someone was touching him as eagerly as Blaine was, he'd probably lack the self-control to hold himself back, too. Hell, Blaine barely has the self-control to hold himself back now.
Blaine licks his lips and darts his eyes back up to Kurt's, and he makes a snap decision before he can remind himself of why he hasn't begged for this yet.
"Kurt," he says, and even though he's managed to slow his hips down, they're still rocking against Kurt's thumb. "Kurt—you gotta—please, you gotta fuck me."
Kurt's eyes widen and he glances down at Blaine's groin. "You—you want that?"
"Want? God, Kurt, I—I fucking need. I'm sorry. I've been trying so hard to take this slow for you and you don't have to say yes, but—but fuck, I need you inside me."
"You—" He pulls his hand back, and stares at it as if he's never quite noticed he had that appendage before. Blaine whines at the loss, and doesn't care how undignified it sounds. He's waited long enough, damn it.
