A/N: Sebastian is trying to seduce his younger boyfriend, but Kurt's mind is somewhere else. A short, pseudo-romantic one-shot for the prompt 'age difference'. Warnings for sex, language, crude humor, anxiety. No underage. Angst, hurt/comfort.
Sebastian runs his tongue down the length of Kurt's spine, lapping at every curve and teasing every plane until he reaches the swell of his hips, and then travels back towards his shoulders, but Kurt, lying beneath him, doesn't budge. Sebastian finds a sensitive spot at the base of Kurt's neck and sucks gently, but even that gets no reaction. He runs his hands down the length of Kurt's sides with barely there touches that usually have Kurt rolling on the bed, dissolving into a fit of giggles, but this time he gets nothing. Sebastian stops, blowing out a long, frustrated exhale, and looks at Kurt, his gaze fixed to a point on the floor, staring holes into the carpet.
"Am I boring you?" Sebastian groans, dropping onto his side beside his lover on the bed. Kurt startles when the bed dips and he turns his head, looking into Sebastian's grass-green eyes, still blown wide with lust even as his hard-on disintegrates.
"I'm sorry, Bas," Kurt says softly. "I guess I was just thinking."
"Well, stop it." Sebastian wraps an arm around Kurt's waist and pulls him close. "Your thinking is killing my boner."
Sebastian's attempt at humor falls short as the smile he was hoping for fades into a frown, and a tremulous one at that. Sebastian sighs, resting his forehead against Kurt's.
"Do you want to talk about it?" he asks, tracing the path his tongue took down Kurt's spine with the tips of his fingers.
Kurt pauses for a second, contemplating, trying to decide if he actually does want to talk about what's bothering him. It seems a little silly now, but as silly as it is, it still makes him glum.
"Come on…" Sebastian sits up on the bed, pulling Kurt along with him, settling his melancholy boyfriend on his lap. "Let me in on the secret. It'll make you feel better."
Kurt nods, but he's still unsure where to begin. Sebastian starts pecking a line of kisses down Kurt's arm while he waits, hoping that Kurt might simply snap out of it and they can get back to the business of mid-morning fucking.
"Well, I'm twenty and you're forty…"
"Yeah…" Sebastian doesn't like to be reminded that he recently left his thirties behind, but apparently it's bothering Kurt also, so he waits to see where this is headed.
"Which means when I'm thirty, you're going to be fifty."
"Okay," Sebastian agrees, his voice getting tight. "And…"
"And when I'm forty, that'll make you…"
"Great! So you can do math," Sebastian snaps sarcastically, reaching a breaking point. His age has definitely been a sore spot with him lately. "What's your point?"
Kurt sighs. He shuts down a bit, looking from Sebastian's eyes to his nose, and then lowering his gaze further until it stops on where his fingertips play over the older man's shoulders. Sebastian watches Kurt's eyes, so expressive and sullen that his heart melts.
"Babe, age is just a number," Sebastian says, though he's hard-pressed himself to find that knowledge all too comforting. "We have more than enough time ahead of us to be together."
"Twenty years is a big gap," Kurt mumbles more to himself than to Sebastian. "I mean, besides music and sex, we don't really have that much in common."
"So, what does that matter?" Sebastian shrugs, continuing the trail of kisses along Kurt's skin.
"Well, what if you get tired of me?" Kurt asks.
"Not likely," Sebastian says, squeezing Kurt tightly in his arms. "I mean, have you seen your ass?"
Sebastian pinches Kurt hard on his left cheek. Kurt squeals and Sebastian laughs, catching his boyfriend by the elbow when he leaps off his lap. Kurt huffs and pulls away to smack Sebastian on the arm.
"I'm serious," Kurt complains. "What if you decide you want to date someone…you know…your own age?"
Sebastian grimaces dramatically, and that finally gets the shadow of a smile from Kurt.
"If I wanted to date someone my own age, I wouldn't have picked you up at that charity dinner, now would I?" Sebastian runs a hand up and down Kurt's thighs, focusing his attention on the way Kurt shifts in his lap with each pass. "I was literally surrounded by middle-aged gay men, but I chose you."
"Okay," Kurt hedges, conceding that point and drudging up another one, "what if you find someone younger?"
Sebastian shakes his head and laughs.
"I can barely keep up with you, babe," he says, looking at Kurt with a fond grin. "Someone younger might kill me."
Kurt's smile slips, his bottom lip quivering.
"And that's another thing…"
"Oh, God, no!" Sebastian drags Kurt back down to the bed, rolling him onto his back and straddling his hips. "Not this again. Seriously, where do I have to stick my tongue to make you shut up?"
"Sebastian!" Kurt gasps, deeply offended.
"Come on, babe!" Sebastian whines. "Give me a break! It's only ten in the morning and you have me dead already!"
Sebastian sees a single tear fall from Kurt's eye and he starts to crumble.
Kurt's tears are Sebastian's Kryptonite.
"Look, babe," Sebastian wraps his arms back around Kurt's torso and holds him tight, feeling his boyfriend's body shake as he fights to hold back a tidal wave of tears, "we've talked about this before. You and I don't have any idea what's going to happen tomorrow, or the next day, or a year from now, or ten years from now. All we can do is enjoy the time we have together. Here. Right here. Right now. Agreed?"
Kurt doesn't answer. He simply buries his head into Sebastian's neck and allows a few more tears to fall. Sebastian rocks Kurt back and forth, shushing him tenderly.
"I know," Kurt manages to whisper – small, and choked, and barely recognizable. "I just want you to stay with me."
"I'm not going anywhere," Sebastian says quietly. "You're not getting rid of me that easily, Hummel. I'm keeping this ass." Sebastian grabs a hold of Kurt's right cheek this time and squeezes hard.
Kurt yelps and wriggles futilely.
"I'm not sure," Kurt groans, lurching left and right, squirming out of Sebastian's iron grip. "I've seen the way you eat."
"What's wrong with the way I eat?" Sebastian argues.
Kurt rolls his eyes to the point that Sebastian can almost hear them rattle around in his eye sockets.
"Beer and bacon for breakfast is not necessarily the picture of a man who takes care of himself."
"Fine," Sebastian says. "Okay, well, if I promise to toss out the bacon and switch the beer to wheat grass, can I please get back to fucking you now?"
Without waiting for an answer, Sebastian lunges for Kurt's neck, latching on with his lips and sucking hard, enjoying the way Kurt moans and tries to pull away.
"I guess so." Kurt stops his struggling long enough to kiss Sebastian gently on the lips. Sebastian kisses him back softly, taking a moment amid the tears and the crude humor to cherish his boyfriend, to kiss away his tears and show him that all is still right in their little corner of the world.
"Thanks," Kurt says, chasing Sebastian's mouth with one more delicate kiss, pressed against his lower lip like a signature.
"Hey," Sebastian says with a wicked grin and a wink, "for the honor of pounding your sweet, tight, twenty-year-old ass, any time."
