Kurt squirms as Blaine tugs off his shirt and slips off his pants.
“But, Daddy,” he whines, “I don’t need a bath now, I’m not dirty!”
Blaine shushes him and smacks his bottom lightly.
“It’s bath-time, baby, so you have to take a bath,” he chastises and Kurt huffs and pouts, glaring at where Blaine is kneeling on the tiled bathroom floor in their apartment. Blaine looks up him, his expression crossed between disapproval and amusement; he’s always had problems keeping character, and he’s struggling not to break right now.
“Daddy, I haven’t gotten dirty today, so I don’t need to take a bath,” Kurt says, his voice patronising in a very childish way. Unlike Blaine, Kurt’s exceptional at playing his part and slips into the role incredibly easily; Blaine would be jealous if he weren’t so busy marvelling.
“Baby, that’s not how it works, now hush, let Daddy get you all nice and clean,” Blaine stands up, walks over to the tub, and dips his hand into the lukewarm water of the bathtub and beckons Kurt over, who still looks petulant and stubborn as ever.
“I’m not dirty, Daddy, so I don’t have to get clean,” he says matter-of-factly.
“Baby, you need to take a bath, now come over here and stop fussing,” Blaine chides.

Kurt huffs and turns away, he eyes the door for a moment and Blaine sees what he’s going to do before his feet start moving towards it. Blaine is up in a second and grabs Kurt around the waist and pulls him back from the door. Kurt squirms and kicks and tries to get out of his grasp, but Blaine forcibly drags him to the bath tub and sit down on the edge, still holding the struggling Kurt in his arms.
“Baby, stop it,” Blaine’s voice is firm and strict and the grip on Kurt’s body is tight. Kurt stops moving immediately, able to recognise when he’s in trouble.
“’m sorry, Daddy,” Kurt offers weakly.
“You should be,” Blaine scolds, “because that was very, very naughty of you, baby,” Kurt looks down and makes a whimpering noise at the obvious disappointment in Blaine’s voice.
“You still have to take a bath, baby,” Blaine says, “but first, I think I should punish you.”

Kurt shakes his head earnestly.
“No, I’ll be good, Daddy, I’ll take my bath, I promise,” he says, but Blaine ignores him and forces Kurt to lie over his lap, bare bottom stuck up in the air and Kurt closes his eyes, still whimpering.
“Don’t clench like that, baby, it’ll only hurt more,” Blaine strokes a hand gently over Kurt’s back. Kurt nods and attempts to relax, though he’s still a bit stiff with apprehension.
“How many do you think you deserve, baby?” Blaine asks.
“None,” Kurt mutters, looking away unhappily and with a pout. Blaine smacks his thigh lightly.
“Stop that. How about fifteen?” Kurt shakes his head and says no.
“Twenty?” Kurt’s eyes widen and he shakes his head again, mumbling something.
“What was that, baby? You have to speak up, Daddy can’t hear you,” Blaine says. Kurt exhales loudly and exaggeratedly.
“Fifteen is fine, Daddy…” he says. Blaine smiles in response.

The first smack lands on Kurt’s left cheek and makes the boy hiss and attempt to stifle a moan.
“Count them for me, baby,” Blaine says and Kurt mutters out a ‘one’, though it’s barely understandable, so Blaine smacks him again.
“Clearly,” Blaine instructs. Kurt repeats the word, possibly a little louder than necessary and with bitterness in the tone, but it’s clear enough to please Blaine, who places another smack on the opposite cheek and waits for Kurt to count it before placing another one back on the left cheek.
Kurt writhes and hisses with the smacks as they become harder each-time. Blaine alternates between cheeks for the first ten, watching then redden quickly and beautifully and silently thanking whatever deity there is that Kurt has such wonderfully sensitive skin.
 “Eleven,” Kurt hissed out as Blaine smacked the top of his thighs exceptionally hard. “Twelve, ah, Th-Thirteen,” Kurt works to keep his voice steady with each landing smack, and struggles not to rut against Blaine’s body too much, despite the aching hardness he’d developed as Blaine spanked him, over and over.
“What’s this, baby?” Blaine’s tone is condescending but affectionate as he reaches under Kurt’s body and feels his penis, hard and leaking pre-cum. Kurt squirms as Blaine swipes his thumb over the head and immediately retracts his hand.

“We haven’t finished your punishment yet, baby,” Kurt makes a noise of protest and begins to buck his hips, seeking friction. Blaine smacks him lightly.
“Baby,” he warns, “stay still and take your punishment like a good boy, we’re almost done.”
Blaine lands the last two smacks on Kurt’s ass, one right and one left; then strokes the sore, red skin softly and soothingly with his palm. Kurt moans happily and pushes back against Blaine’s hand, liking the comforting strokes against his skin.
“Shh, baby,” Blaine says gently as he moves Kurt so that he’s sitting in his lap, noting the way Kurt hisses when he settles. Blaine wraps a hand around Kurt’s erection and pumps slowly, using his other hand to stroke over Kurt’s torso.

It doesn’t take Kurt very long to come, keening loudly and pressing his body back against Blaine’s as the white fluid spurts over his bare body in thick ropes.
“Oh, baby, look at you, you’re all messy,” Blaine coos. Kurt flushes bright red and looks away.
“Guess you do need a bath after all, don’t you?” he says, sounding much smugger than he should be allowed. Blaine pushes Kurt off of him for a moment and dips his hand in the tub, feeling that the water is now icy cold. He turns back to Kurt, who is grinning in a way that makes Blaine want to hit him for being such a brat.
“Is the water cold, Daddy?” Kurt asks, his voice a mockery of innocence, “better run another bath, then, Daddy,” he says smugly, as though he’s won.
Kurt cackles like the obnoxious little brat he is as Blaine lets out the water and turns the taps, shooting glares in Kurt’s direction as the boy doesn’t even try to hide his giggles at Blaine having to do this all over again.

Kurt’s laughter stops as the come on his chest beings to dry and he looks down and cringes.
“Are you done yet, Daddy?” he asks unhappily.
“I would be if you hadn’t been so insistent on misbehaving,” Blaine reminds him.
Kurt has the sense not to say anything back to that, though Blaine can hear him grumbling about how gross it feels and how much he wants his bath now.
Blaine doesn’t even feel guilty for the vindictive smirk on his face.

End.
