a little drabble for human robby x puphybrid!dennis bc the concept gets me hard
Robby stares at the pup kneeling at his feet, floppy, brown ears flicking in anticipation for his next command.
He combs a hand through Dennis's soft curls, watching the gentle sway of his fluffy tail pick up speed under his touch.
"You ready for a treat, sweet thing?" Robby croons, moving his hand to rest on top of his bulge, toying with the zipper of his pants.
Dennis's eyes follow the movements eagerly, mouth dropping open to let his long, pink tongue loll out. He nods frantically, tail fully wagging, ears standing at attention.
Robby chuckles, amused as he watches the pup try to inch closer to his clothed cock.
He fists a handful of Dennis's hair with a firm hand.
"Ah, ah, ah," Robby tuts chidingly, tilting Dennis's head up further. "What do good boys say when they want a treat?"
Dennis whines, petulance dripping like honey from the soft sound. He attempts to fight against Robby's grip, pouting once he realizes his efforts are futile.
"Thank you, daddy," The pup scoots forwards, panting as he looks up at Robby imploringly. "Please, I've been so good, need it in my mouth."
Robby softens, biting back a groan at the sight of Dennis buzzing with excitement to get him in his mouth. If he's honest, the desperation is starting to bleed onto him, and his cock has started leaking in his underwear.
"Good boy, Den," Robby grunts, making quick work of unzipping his pants just enough to get his cock out. It springs out, tip red and sticky, and Robby fits one hand around the base.
"Go slow and watch your teeth."
Dennis dives in before the words have finished leaving Robby's mouth, burying his face in Robby's bush with a long inhale. He moans softly, eyes glazing over as he rubs the wiry hair against his cheeks.
Once he's had his fill, he moves on to the shaft, leaving soft kitten licks at the head.
Robby groans, letting his hand drift back to Dennis's hair. His fingers dig in just slightly, if only to hear the small whimper Dennis lets out.
"Such a sweet boy," Robby grits out, trying not to buck his hips in the pup's face. "Keep going, baby, put it in your mouth."
Dennis obliges immediately, wrapping his plush lips around the head, slowly guiding himself down until his nose hits Robby's pelvis. He gags softly, throat convulsing wildly around the length of Robby's cock.
"Fuck, boy," Robby moans, toes curling in his socks. "Trained you up real nice, huh? Take it all in, just like that."
Dennis pulls back, just enough that he can swirl his tongue around the tip, drool starting to drip from his chin to the expanse of his neck. The pup stares up at him, determination clouding those teary blue eyes.
Dennis's hands move to his hips, grounding himself as he starts to fuck his own throat on Robby's cock, mouth working with the fervor of a pup wanting to impress its owner.
It works, too, because fuck, his mouth feels like silk, getting wetter with every moment it spends on Robby's cock. The knot in his gut tightens, and he knows this won't last as long as he planned.
His hips start to move against his will, fucking his cock impossibly deeper into the pup's throat. Dennis's claws bite into the meat of his thigh, penetrating the thin material of his pants.
Dennis whimpers around his cock, a small, broken thing, and Robby catches sight of his legs pushing closer together where he kneels.
"I know, puppy, I know," Robby teases, hand moving to rub a string of drool into his chin. "Sucking daddy's cock gets you so turned on, hm?"
Dennis nods, doubling up his efforts. He relaxes his throat around the length, allowing it to fully slide in as he stays there for a few seconds.
Robby's stomach clenches, teeth grinding against each other in an attempt to stave off his impending orgasm. Right when Dennis starts to clench his throat, Robby grunts, pulling the pup off completely.
He watches as Dennis sucks in a wet gasp, attempting to catch his breath, soft sounds falling out with every shaky exhale. The pup stares up at him, incredulity and confusion swirled into one pitiful expression, pout returning to his swollen, wet lips.
"Don't look at me like that, pup," Robby coos, petting him with a shaky hand. "Your mouth is too good and I'd still like to fuck you tonight."
Dennis brightens immediately at the praise and the promise, tail wagging fast enough that the motions melt into one fluffy blur. He starts to paw at Robby's leg, shifting back and forth on his knees.
"Alright, up you get, sweet boy," Robby pats his cheek, bending at the waist to pull Dennis up by his armpits.
Dennis stands, immediately slumping into Robby's arms. He rubs his messy face against the smooth fabric of Robby's sweater, happy whines and snuffs leaving him.
Robby smiles fondly, resting his hands on the softness of the pup's waist, as he looks down at the mess they made on the floor. There's a small puddle of slobber in front of a much larger pool of slick, right where Dennis's cunt would've been.
"Oh baby, are your puppy parts leaking?" Robby asks, tone soft. He fits a hand between the gap of Dennis's thighs, and sure enough, his cunt is slick, the puffy skin heated with arousal. The pup whines into his chest.
"Don't worry, daddy will take care of it." He throws Dennis over his shoulder in a fireman's carry, enjoying the indignant squeak his pup lets out.
As they make their way to the bedroom, Robby spares a thought that he might be the luckiest owner in the world.
