"Mmmm...!"
"You're being quite noisy for a cockwarmer don't you think, Katsuki?" Tsunagu sighs, dropping his gaze under the desk. The intern in question is nestled between his legs, mouth pressed up against the soft mound of hair there.
He runs a hand through the sandy blond hair before gripping it to pull his head back.
"You've made quite the mess too, haven't you?" Tsunagu chides when he sees the moisture on his chair and covering Katsuki's chin.
"What a mess." He says, catching some drippage off the boy's and feeding it back into his mouth. Katsuki sucks on his finger greedily, moaning at the calloused pad rubbing across his tongue.
Tsunagu tugs his hair again, pulling him back gently.
"Be a good boy and stay quiet for me now, Katsuki." The boy nods, glassy eyed and relaxed before leaning back in for more. Tsunagu guides him, pressing him back between his legs, back to the blond curls surrounding his cock.
Tsunagu hums when he feels Katsuki's lips against his- when he feels them slide open, tongue running against his folds and dipping into his hole. He tips his head back, sighing at the sensation of being savoured .
Katsuki's lips wrap around him, suckling gently before relaxing and holding Tsunagu in his mouth.
Tsunagu pets his hair with soft affection, slipping his fingers between the blond spikes and massaging the scalp beneath.
He can feel Katsuki slacken against his leg, his head lolling to rest against Tsunagu’s thighs, his body relaxing between his calves. He pets him like a docile kitten resting in his lap- sweet and full of endearment, The warmth around his cock is pleasant too- relaxing.
Just enough to make him wet but not throbbing.
Tsunagu turns his attention back to his paperwork but his hand remains in Katsuki's hair, ruffling gently.
At some point Katsuki starts to zone out too, he notices. Dipping in and out of awareness as he relaxes into Tsunagu’s touch. His tongue twitches lightly every time he comes back but it doesn’t take long for him to let go again.
Tsunagu rubs the bridge of his nose and leans back in his chair. The last of his paperwork is finished and piled neatly in his outbox for pick up. It didn't take long- not with Katsuki still resting between his legs but it was long enough for the boy to start getting restless.
He runs his finger along the seam of Katsuki's ear, tapping lightly to bring him back to attention.
"You're doing so well, Katsuki. Such a good boy for me." His voice is soft, low, soothing. Bleary red eyes look up and his heart floods with warmth.
"Such a good boy..." He murmurs, gently pulling Katsuki away from him. He takes in the sight of Katsuki, flushed and disoriented as he blinks his way back into awareness. He moves his lower jaw around, snapping it open and closed a few times before returning Tsunagu's gaze.
It's fiery and full of life- back to usual.
"You did so well, Katsuki." Tsunagu cups his jaw and strokes at the hinge.
"I told you I could do it." Katsuki croaks, his voice a little hoarse from disuse.
Tsunagu chuckles and continues petting him.
"I'd say you deserve a reward, don't you think?" And the way Karsuki leans in to bite his inner thigh has him shudder in excitement.
"I'm inclined to agree." His lips drag against the soft skin between Tsunagu's legs. His teeth nip playfully as they go, leaving little marks. Strong arms wind around his thighs to pull him forward and he yelps in surprise.
"Katsuki!" Tsunagu's protest quickly turns into a gasp when Katsuki takes his cock into his mouth again, sucking hard this time.
The older man moans, fingers digging into the cotton weave of his office chair. He trembles when Katsuki spreads his lips with deft fingers and laps at him, tongue dipping into his hole ever so lightly.
He knows he's making an even bigger mess down Katsuki's chin but that doesn't stop him from pushing his hips against that talented tongue. Knuckles drag over his opening before a finger presses in in in - and Tsunagu has to remember to breathe when Katsuki sucks his cock again.
Calloused fingers press into him- not one but two now, spreading him open and curling right into the spot that makes his hands fly to grip Katsuki's hair.
It only encourages him more, Tsunagu finds. Katsuki sucks harder, presses further, finger fucking him until he's curled forward and clutching blond hair in both arms.
"Fuck! Ah- Katsuki!" Tsunagu can't imagine how desperate he must sound. He's so close to release and he's probably holding Katsuki too hard and his hips can't seem to stop moving against the boy's grip but the pressure building in his system is like steam in a kettle and his cock is calling- no, begging for release and it's not until Katsuki curls his fingers up and hard that he boils over, his insides tightening and release splashing out and over Katsuki's hand.
Tsunagu gasps out his release, his whole body tensing. His fingers twitch, his toes flex against the soles of his shoes, his thighs twitch against the sides of Katsuki's shoulders until he lets his body go, slumping back into the seat, breathless and satisfied.
Katsuki on the other hand looks excited as ever; like the cat who got the cream- literally. Tsunagu relaxes against his chair as he watches the boy suck down the fingers he'd been using. He cleans them slowly, carefully licking every inch before doing the same with the mess between Tsunagu's thighs.
"Ever the overachiever, it seems." He hums running his hand through the ash blond hair again.
"I told you I’d be good," Katsuki says against damp skin, "At
everything
."
