Kurt wrinkles his nose, turning his head and nuzzling further into his pillow. He feels a tickle against his toes and he furrows his brow, beginning to fully wake up as he feels air being blown onto his pinky toe.

He opens one eye first, blinking harshly at the light coming from the window, and then the other, until he's staring sleepy eyed at his bookshelf.

And then he takes in a deep breath, and tenses.

He smells nail polish, strong and heady.

And fresh.

Oh no.

Kurt's first instinct is to jolt up, but he knows that if he does, the situation could turn out ten times worse. So he ever so slowly lifts his head to find Blaine sitting at his feet, his little pink tongue poking out of his mouth as he paints Kurt's toenails with intense concentration.

Blaine swipes his stubby thumb across Kurt's toe, rubbing off a smidge of polish that had gotten on Kurt's skin, and then he looks up, freezing when he sees Kurt awake. Blaine's eyes widen dramatically, and he drops the wand of the polish, scrambling backwards on the bed, awaiting Kurt's reaction.

Kurt sits up slowly and assesses the damage; his toenails are all bright pink, while his fingernails are blue, and thankfully, there's only a small spot of polish on his bed sheets, something he can clean easily.

"I'm sorry!" Blaine's voice is a little shaky, his eyes bright and beginning to tear up.

"Oh, Blaine no it's okay, shh, sweetie please don't cry! I like it... it's very um, colorful."

Blaine's ears perk up at that, his tail starting to wag happily.

"Really? You like it?" He asks, crawling towards Kurt and plopping down in between Kurt's legs.

Kurt smiles down at Blaine, scratches behind his ears, laughing to himself at the messy paint on his fingers. Kurt just can't be upset with Blaine though, not when he looks so happy and earnest.

"Of course I love it, B, you did a really great job honey."

Blaine preens, butts his head against Kurt's hand, his tail thumping wildly on the bed.

"Thank you, Kurt! I wanted to do something nice for you for your birthday! And every time your Rachel and your Mercedes and your Quinn and – I forget the rest of their names sorry Kurt – come over you always make their nails so pretty! And they always look so happy after, so I wanted to make yours pretty too!"

Kurt smiles bright at that, letting out a small laugh, and he picks up Blaine, holding him close to his chest.

"How did you know it was my birthday, B?"

Blaine grins toothily up at him, hands twisting the fabric of Kurt's shirt.

"Mr. Burt told me! He said today was a special day 'cause you're turning sixteen and you're a man now! Oh! Kurt, hey! You're old now!"

Kurt laughs, turns the two of them over and plops Blaine on the bed, fingers tickling along Blaine's stomach. "Oh, I'm old am I, huh? Too old for you now, little B?"

Blaine giggles loudly, his curls bouncing, tail thumping loudly as his tiny little body shakes with laughter. "No! No, not too old! You're my Kurt, you'll never be too old!"

Kurt slowly stops his tickling, glancing fondly down at Blaine as the puppy catches his breath.

"Your Kurt, huh?"

Blaine nods up at him, his hands rubbing at his belly. "My Kurt. And I'm your Blaine."

Kurt smiles bright, picks Blaine up and hugs him, Blaine's chin tucked over Kurt's shoulder. "Why yes, yes you are."

"Now," he says, holding Blaine out at eye level, "how about we make your nails just as pretty as mine?"
