Chapter Text

It starts like this:

 

Carlos pressing into Jannik's space, wrapped around his back as Jannik tries to dry his hands. They're in the restrooms, the calm ones Jannik likes to use because he never has to figure whether or not to look the other men in the eye when both parties know what they’re doing there. So Jannik has his habit, and Carlos knows about it.

 

Carlos' hands travel along the expanse of his suit, sliding under the lapels and holding Jannik close. 

 

"Do you know how hot you are tonight?" He asks, and Jannik softly laughs.

 

"Given the way you crowd me, I'd say acceptably so?"

 

Carlos whines, blunt nails digging into the fabric of his shirt.

 

"I want you." He goes on, and Jannik laughs, short and airy.

 

"Where anyone can find us? 

 

Carlos sighs into him, chest to back, long and suffering.

 

"But waiting is a pain." He admits. Jannik turns around, hands wrapping around Carlos' waist.

 

"Isn't it worth it though?" Jannik kisses Carlos' temple, folds around him and kisses him deep, with intent. Tongue brushing against Carlos' bottom lip, Jannik drinks in his soft whine, licks into his mouth and meets him in the middle. He kisses him the way Carlos likes best, until his breathing becomes laboured and it's become painfully obvious the both of them have disappeared from the crowd.

 

Jannik pulls away with some reluctance, Carlos' gaze fixed on him: his eyes, his lips, the curve of his neck as he swallows nothing but spit.

 

"Come on now, be a good pup."

 

There's a glint in Carlos' eyes, the excitement of engaging in a game, the underlying promise that if he's good, he'll be granted a reward. 



What follows :

 

Carlos never gravitates far from Jannik. He can see how hard he's trying not to forego social niceties to join Jannik. It's mostly players, a gala to celebrate the end of the season, but it's not like Carlos can even think of flying under the radar. Not when he's number one. Especially not when he's a ray of sunshine. Jannik likes that about him, the warmth of his heart and his sharp mind. Jannik never stood a chance in the first place.



Jannik never gravitates far from Carlos. If anything, he was the one who fell first for some kid in a Challenger. The difference between them is that Jannik likes to endure, to be on the receiving end and finding domination through hardships. Carlos takes. Carlos wants and he makes him his.

 

So Jannik plays a game with him. He'd never say Carlos is more enthusiastic, but he has to concede Jannik likes to torture him a little. He brushes past him, hands grazing at Carlos' shoulders, a "Sorry" murmured into his ear, a burning look from across the room, a button popping off. 

 

Carlos looks more and more distracted, eyes fleeting towards Jannik. He excuses himself with the reasoning of a tournament's fatigue. 

 

Now comes the final part. Jannik waits.

 

He waits until he knows Carlos is back at their hotel, waits until the last niceties have been exchanged and it's not suspicious that he leaves.

 

And there's the reward :

 

Jannik closes the door behind him, the hotel room's lights dimmed. He knows what he wants.

 

Carlos is waiting on the bed, shirtless, a pair of joggers sitting low on his hips. He’s not even pretending to be busy, hands on his lap, gaze following Jannik’s movements. 

 

“You’ve been a good pup,” Jannik tells him, loosening his tie. No butt grabbing, no winks, he's learning how to behave.

 

Jannik guides Carlos back into the bed, crawling over him until he’s kneeling over his body, tie pooling in the space above his collarbone, a knee between Carlos’ legs. 

 

“What do you want?” Jannik asks him, because good pups should be rewarded.

 

Carlos exhales, a little shudder into it.

 

“Want you. Your hands on me.”

 

Jannik hums.

 

“You’ll have them, my wonderful pet.”

 

He kisses Carlos' cheekbone, teeth biting into the soft flesh of his neck, lips closing around a nipple.

 

“Don’t be upset, I’m tired. I just want to focus on you.”

 

Carlos makes a pained noise, Jannik knows how much he likes making him feel good. Still, he sees how relaxed Carlos looks, the slight glaze in his eyes. That's more than enough for Jannik.

 

He can feel how hard he is against his thigh, how he's starting to chase friction, hips going up to rut against him. Jannik tuts at him.

 

“Darling, let me do it.”

 

He spits into his hand. In a fluid motion, Jannik slides into his joggers, long fingers wrapping around Carlos. The other makes a choked sound.

 

“Feels so good.” Carlos tells him, voice barely above a whisper, raspy from a night of exchanging niceties with other players.

 

“You’re such a good puppy.” Jannik says, steadily touching him.

 

“Wanna be good.” Carlos answers.

 

Jannik speeds up, a little meaner on the flick of his wrist.

 

“You're already perfect.” Jannik comforts him, kissing him more urgently. He feels warm all over as Carlos moans, bucking into his first.

 

“Just for you.” Carlos goes on. It ignites a fire in Jannik.

 

“Just mine.”

 

Carlos whines, soft moans tumbling from his lips.

 

“Your pup.” He murmurs.

 

“Let go, baby.” Jannik soothes him.

 

Jannik touches him the way he knows Carlos likes, a little too dry to the touch, short strokes, a pace that leaves no space for Carlos to even form a thought.

 

With a choked moan, Carlos spills over his navel, offering him a reedy whimper. 

 

“You did so well.” Jannik promises him, kissing his collarbone, his jaw, his lips. “We’re gonna shower after?”

 

Carlos tries evening his breathing, laughing a little.

 

“Give your man a minute.” He asks of him.

 

Jannik laughs. “Sorry.” he answers.

 

Carlos opens an eye with a toothy grin.

 

“Y’know I love you, right?” 

 

Jannik hums, looking away. He pretends to act aloof but he knows Carlos can see the redness of his cheeks.

 

“The feeling's mutual. Come on, let’s get you clean before it dries. Terrible feeling.”

 

Jannik likes how happy and sated Carlos looks. He really wouldn't mind being the reason for it for a long time. 

 

Carlos grins at him, eyes crinkling.

 

“Watcha thinking about?”

 

Jannik tries smiling carefully and still ends up answering Carlos’ grin.

 

“Sappy thoughts.”

 

“Will you tell them to me?” Carlos caresses Jannik’s arms.

 

“Only if you wash my hair.”

 

Carlos barks out a laugh.

 

“Deal.”
