BakuDeku – direct sequel to this – puppy play; rough treatment; watersports; dominance display; restraints – Deku needs to establish who is top dog.

There’s saliva dripping to the floor as Bakugo sits back on his heels, head hung low, chest pumping as he pants. He’s been trying for a while with more and more desperation to get the muzzle off but nothing has worked.

Midoriya has been sitting on his hands for the better part, less he’d give in and help his puppy out of the restraint. When Bakugo glances up at him, he quickly schools his expression into something hard and neutral.

There’s sweat beading along Bakugo’s hair line. There’s no doubt his hands are just as damp, but there’s no sign of him using his quirk. He looks like he’s absolutely hating every second of what’s happening to him, but he’s not using any of the outs available to him.

When he seems to have caught his breath, he throws himself into the second round: putting himself flat on the ground and using his curled-up hands to try and push the muzzle off of his face.

Midoriya watches him for a while before deciding that he’s been playing at being a brat for long enough.

He stands abruptly. That gets Bakugo’s attention. His red eyes look murderous as he stares warily at Midoriya, but he does not back away when he starts to advance on him.

He bares his teeth and growls ferociously as Midoriya squats in front of him, but that is all.

“Good boy,” Midoriya murmurs and pats his head. There’s no hesitation there. His face is set in grim determination. Bakugo stills for a second, his eyes holding a curious squinting expression as he seems to think things through.

Then he pushes his head into Midoriya’s palm.

.o.

It is not like he’s capitulated; he’s just shifted tactics. Bakugo is a wily little pup. One that has been horribly spoiled up until now; and while Midoriya does not know whether he’ll be able to train him, he is at least willing to try.

Bakugo might have thought he’d quickly lull him into getting the muzzle off of him, because when Midoriya does not do so and instead divests his puppy of his clothes to get his hand on his dick – already standing at attention; as ruddy red as Bakugo’s neck becomes when he’s screaming his head off in rage – he starts becoming rude again.

He snaps at Midoriya, then, when Midoriya doesn’t so much as flinch, tries to headbutt him.

That earns him a big, rough hand in his neck almost slamming his face into the floor.

Midoriya is on him a heartbeat later, his knee digging between Bakugo’s shoulder blades.

“*Bad* boy, Kacchan,” he hisses. He fumbles with something Bakugo can’t see and a moment later, he collars him with a wide strip of leather. “You’re not getting a treat like this!”

He pulls him roughly at the collar and Bakugo has to scramble to follow, lest he’ll be choked. He’s off-balance, trying to figure out Midoriya’s next move, but since he’s not behaving like usual, he does not have any frame of reference to go on.

“I think you need to understand who is in charge here, Kacchan,” Midoriya says ominously, his voice wavering only slightly.They’re in the bathroom now, and Bakugo starts vaguely panicking, but his uncoordinated attempts at bracing himself on the slick tiles are thwarted by Midoriya simply dragging him along with a hand around his collar.

He shoves him into the shower stall, and stares down at his puppy. Bakugo’s red eyes are wide, his mouth behind the muzzle a soft ‘o’ of surprise as he just watches Midoriya fumble with his pants.

He can feel his ears slowly starting to grow hot. He can’t look into Bakugo’s eyes when he pulls his cock out, but then kicks himself mentally and takes a deep breath. He has to be dominant.

He has to be dominant.

He has to be dominant.

“*I* am the one in charge, Kacchan,” he tells him with a firm voice. “You have to behave.”

As Bakugo stares at him, confused and a bit frightened – and God… it should not turn him on so much – he realizes he’s still hard; his gorgeous cock still standing at attention for Midoriya. Deku.

Bakugo is too surprised to do anything when the piss hits him first. He jerks and makes a weird whining sound, almost questioning, but does nothing else. Then the situation seems to click and he wants to… do *something*, squirm away maybe, but Deku has his hand around his collar again in no time.

He twists until Bakugo has to follow it, one shoulder tilting towards the ground, the other up; face inevitably turning right into the hot spray of piss as Deku holds him in place and makes him take it.

He can see the absolute shock and disgust in Bakugo’s face, but when the warm liquid starts pooling in his crotch, his hips make a canine jerk upwards and his eyes become unfocused.

“There you go,” Midoriya croons under his breath, his face probably ridiculously hot. “There’s a good puppy. I’ll make sure you know who owns you…”

He stares at Bakugo’s mouth; pink and soft and slack. He thinks about him being better behaved; of being able to take the muzzle off of him so he can drag his face between his thighs and have him rim him like a good puppy.

When he’s done, it is very quiet in the bathroom, safe for both their heavy breathing. Kacchan’s eyes are heavy lidded. He looks absolutely out of it.

Eventually, he leans forward and starts nuzzling against Deku’s soft, spent dick.
