The first thing that Izuku’s brain registers is the stabbing and uncomfortable feeling in his gut. Then, it’s the feeling of a large, calloused hand gripping the scruff of his neck and refusing to let him move. Somehow, he fights off the rapidly growing urge to fight and flee, if only because he knows not to let himself at this point. He’s groggy, disoriented, and heavy-limbed, but he’s eventually aware enough of his surroundings to understand what’s happening.
Almost entirely involuntarily, a soft and pitiful whine breaks through his lips, and the hold on the back of his neck loosens momentarily while the ache dulls. It’s only enough to allow him to breathe a bit better, but it soon tightens again and keeps him in that new position. The ache continues, a rapid back-and-forth push and pull that feels as if it’s all the way in his stomach. He personally thinks it’s too early for this kind of thing, but Sir has never cared much for what he feels regarding these kinds of things. So, he raises his hips just a little higher to make it that much more bearable.
He feels lips brush against one of his ears, nipping at the furred skin for a moment before speaking.
“Good morning, Pup,” Sir purrs, squeezing down on the back of his neck, “Did I wake you?”
There’s no remorse anywhere in his voice. Izuku wasn’t expecting it. He’s never sorry for waking his dog up like this, especially because he just gets to toy with him more once he’s fully awake. It’s been happening for years at this point, so he’s not really phased anymore.
He lets out a soft hng in response at first; his tongue is still so heavy with sleep. He licks his fangs, awareness of the other sensations finally settling heavy in the back of his mind. The bed is creaking slightly, the sheets under his thighs are soaked, and he can feel the familiar stinging of open bites on his shoulders. Sir hadn’t been home when Izuku went and curled up in his bed, so he must’ve been pretty desperate when he got home. Usually, he tries to stay awake and greet his master, but his patrol had gone on longer than usual the night before.
With another soft grunt and whine, Izuku manages to croak out a response.
“‘S’okay. Was waking up anyway.”
He wasn’t. Shouta knows he wasn’t. He can feel the sharp grin his words bring pressing against the back of his head in a twisted mimicry of a kiss. His hips never slow, but his hands move to his hips instead. He yanks him back onto him with each thrust, the movements growing sloppier and rougher. He’s chasing his own need now, and he doesn’t particularly care if Izuku gets off alongside him or not. He’s not always selfish when it comes to pleasure, but he supposes it’s just one of those days.
Pup doesn’t really care at this point. Sometimes he really needs to cum, but it’s not that important right now; Not for him, and not for Sir.
He’s pretty sure he zoned out. He does that sometimes. He’s once again brought to awareness by his master pulling back and out with a soft grunt. That all too familiar hot, slick feeling of his release trails down his thigh, and he huffs. Now, Sir will clean him up and pull him out of bed, just as he always does, and-
Izuku lets out a confused sound as those rough hands gently roll him onto his back. He gazes up at his owner with wide eyes and cocks his head to the side. The man smiles as he takes his place over Izuku, his expression almost tender. It’s a strange look on him, but it’s becoming more and more common these days. He doesn’t know how to feel about that. His master is growing soft in some ways, and Izuku doesn’t know if he should trust it.
He watches with a mixture of bemusement and anxiety as Sir bends down and kisses his collarbone. His lips never stop moving, trailing down and over the curve of his small breasts, his stomach, and the roundness of his mound. It’s only right then that he’s made aware of what exactly is happening. He inhales sharply, startled by the feeling of his tongue right against his clit. He jerks slightly with a yelp, but Sir must’ve been expecting it. He grips onto Izuku’s hips as he continues with languid strokes.
He’s…
“M-Master-?”
His voice crackles and stutters into a moan when Sir wraps his lips around the head with a slight suction. His ears are ringing. He’s only ever done this once before, and it was because he thought it could relax Izuku enough to let him fuck him. He was right, kinda, but that’s not what’s happening here. He doesn’t have anything to gain from this, not after he just came inside and left him a mess. Clawed hands scramble to grasp the sheets, tearing into the fabric with their strength. It speaks volumes about how content Sir is that he doesn’t immediately pull away and snap at Izuku for destroying it.
He just hums, lifts Izuku’s hips just a bit higher, and lets his tongue delve deeper. The fact that he’s doing this to Izuku, cleaning up his own mess, all while making a new one… He feels almost dizzy with a mixture of confusion and pleasure.
They spend a while like that: Sir lazily eating him out, going slow enough to make the pup nearly sob, and Izuku writhing, moaning, and pleading with him. He feels wrung out already, and the heat in his gut feels less like a warm bath and more like a red-hot iron rod. He’s too close. He can’t stop and ask, he can’t try to get Sir to pause, and he can’t do anything but take it. His body aches from how hard he’s shaking with his restrained movements.
Finally, after what was likely just a few minutes but felt like twenty years, he cums. He’s sobbing as he does, trembling so hard he fears he’s going to fall apart. Sir laps at him through it all, humming and stroking his stomach gently. It’s only when Izuku starts clawing at his head to get him to stop that he does. When he pulls back, he’s still smiling at Izuku. He usually grins or smirks, but this isn’t that.
Again, he’s confused.
“That feel good, baby?” Master coos, reaching up to brush Izuku’s bangs from his face, “You did so good for me, y’know? You’ve been so good recently, I just thought I’d give you a little reward.”
Izuku’s face feels like it’s on fire. A reward? This was a reward? It certainly felt like a reward, but… Rewards from Sir are typically things like a new stuffed animal or a blanket. Something tangible and long-lasting. He’s never given him something like this.
Sir is looking at him with something expectant in his gaze, and Izuku realizes he’s been silent for a little too long. So, he licks his lips and nods slowly.
“Yes,” He breathes and leans up into the gentle touch of Master’s hand, “Thank you, Sir. It was really nice.”
Sir grins, sharp, satisfied, and hungry. Izuku shivers and shies away a bit. His master just coos again and pets him like he’s comforting a scared animal. He’s not used to this. He doesn’t think he likes it yet, but he knows he will. Sir has a way of making him like things. He’ll be okay.
