"There you go!"
Izuku grins widely and stands. "Come on, boy!"
The dog seems to nod along as he speaks.
"Oh, man! Come on, puppy! I just showered at the gym, now I'm going to need to clean myself off again!" Izuku groans.
They settle on the couch to watch TV,
Once they come back in, Izuku says, "I don't know about you, puppy, but I'm ready for bed... Be good, okay?"
When Izuku's breaths even out in sleep, Katsuki hops off the couch and pads into the bathroom before shifting back into human form.
Eventually he'd have to tell the man the truth,
The dog recoils and snorts.
"Okay, not Spike... Goldie?"
Another shake of the dog's head.
They make their way out to Izuku's compact car, stuffing everything in the trunk while Kacchan hops into the passenger seat.
No matter how well-groomed Kacchan is, the whole apartment has a distinct smell to it. He knows that dogs mark their territory, but it isn't that...
"You're my good guard dog, huh, Kacchan?" He grins.
Katsuki sighs as he shifts back into his human body twenty minutes or so after Izuku has left for a full day of classes. The first thing he does is go to the dirty clothes hamper, digging out last night's underwear. With his sensitive nose, he finds them almost instantly.
Not that Deku knows that just yet, but he will soon enough. Katsuki's been thoroughly scenting him.
(tbc since it's late and I need sleep!)
A few general TWs for upcoming events:
-cum & piss marking
-light bestiality (non-penetrative)
If one or more of these isn't your cup of tea, please back out now! Otherwise, I hope you enjoy what's coming up!)
Kacchan whines softly, nudging at Izuku with a cold nose.
Once Katsuki is good and certain Izuku is fast asleep, he shifts to his human form. He licks his lips as he strips Deku completely bare.
"Don't worry, Deku. I'll make sure you're satisfied."
Once Izuku is nude, Katsuki leans down and starts to scent him thoroughly; rubbing his wrists and neck against every inch of skin he can reach. He leans down and murmurs in Deku's ear,
Even unconscious, Deku's body starts to react to the praise. His sweet little Omegan cock stirs to hardness as he lies, splayed out and open, on the bed.
No, tonight is all about that delicious little hole.
Even in human form, Katsuki's tongue is long and broad; perfect for digging deep into a slick-damp entrance.
He wants Deku awake the first time they fuck; wants to hear him crying out for his Alpha's dick, his Alpha's knot.
He keeps going until Deku's ass contracts around Katsuki's tongue and fingers, a strangled whimper escaping his throat as a gout of slick pours from his hole and his cock spews cum all over his stomach.
Fuck, but he can just imagine shoving his dick into Deku's mouth, using his throat like a cock sleeve before coating those beautiful freckles with his seed. He'd watch Deku eagerly lick up all the cum,
He doesn't do that tonight, though. It's a little too soon, plus he doesn't want to get cum anywhere *too* suspicious. So he limits himself to spraying over Deku's chest and stomach, overlaying the pearly fluid already collecting in the dips and hollows.
Once he's swiped up most of the cum, he feels the insistent pressure of his bladder--he'd been holding it for a while,
With a sigh of relief, he lets go, the pressure easing as he pees all over Deku's lower body. He focuses most of the stream on his hole, which is still gaping a bit from his fingers and tongue.
Once the stream has eased off, Katsuki gently rolls Deku out of the worst of the puddle. He'll wait a bit to give it time to really soak in before he shifts back.
No matter. It's Izuku's last day of work before he takes 10 days off for his heat. Once he gets home, it'll just be him and Kacchan. He's already made arrangements:
That afternoon after work, Izuku sets up in his little workout room to record a tutorial for his social media account.
He's wearing tight shorts and a loose, oversized sweatshirt that he's cut the sleeves off of. When he lifts himself up into an elevated plank,
He holds the position for about 15 seconds, engaging his core muscles to keep his back straight. Before he can lower himself down,
He tries to push Kacchan off, but the oversized shirt is keeping them bound together. "N-no," Izuku admonishes the dog,
"Kacchan! Please!" He cries out when his dog's muzzle finally moves away from his mouth. He honestly doesn't know if he is begging him to stop...
Kacchan's hips rock faster and faster, rutting against the thin spandex shorts and the cock straining the fabric. Izuku cries out when the tip of Kacchan's dick catches on the bottom hem of one of the legs and slides inside the shorts without warning.
Then, all of a sudden, hands are tugging at the waist of his shorts. His eyes fly open to meet amused, crimson irises and smirking lips.
"God damn it, Deku! I am Kacchan!"
He smells like *Alpha.* Izuku never noticed that before--never made the connection between the pungent aroma and a territorial "dog."
Finally, everything seems to click.
A very attractive, very nude, very *Alpha* shifter.
The man--Kacchan--nods. "And you're my mate. Fucking *finally.*"
"C'mon, Deku, I know your shitty nerd brain can keep up better than that." He leans down,
As if to punctuate his point, he rubs the head of his cock against Izuku's hole, making him groan and buck his hips.
"God, I've dreamed of this for months," Katsuki growls. "Gonna fuck you so good, Deku."
"Nah, you're definitely a Deku. A useless little Omega who can't even cook for yourself; I'm gonna have to take care of you from now on, especially once you're fat with my pups."
"None of that, Omega. Let me fuckin' hear you scream."
A moment later, he's picked Izuku up by the hips,
Izuku has never been fucked by a shifter, but that tongue is *glorious.* It's reaching so deep inside him, he can feel it sliding against his prostate.
Katsuki pulls away, tongue lapping at the entrance to gather up any remaining slick before he replies. "What do you want, shitty Deku?" he growls. "You wanna cum on my tongue, or my knot?"
As if there's any question.
"Good answer." Katsuki flips him onto his stomach and positions the blunt head of his cock at Izuku's stretched, soaking wet entrance. "Now tell me, who do you belong to?"
"Alpha!" Izuku sobs.
"Who's gonna fill you up, make you fat with pups?"
"Good boy!" He replies with a grin, tone a mockery of all the times Izuku thought he was talking to a simple dog. "Here's your treat for being so good and obedient."
Izuku *screams* at the feeling of being split open, stretched almost too far.
Kacchan is his Alpha. Has protected him, kept him safe, made him happier than he's been in a long time.
Katsuki has ruined him for anyone else.
He sobs, helpless to stop the freight train of his orgasm as he's filled.
"Please, please," Izuku begs. "Knot me, Alpha, need your knot!"
"Gonna give it to you soon, don't worry."
Izuku's sobs as he clenches down hard, tears streaming down his face. "Ka-Kacch-haaahn, haah,
"Oh no you don't, shitty Omega, you don't come unless it's on my knot!" Katsuki's knot is ballooning rapidly, tugging on Izuku's hole every time he thrusts.
"Haah, I, haaaan't," he whines; he tries to rock back onto Katsuki's dick,
"Take it! Take my knot and get pregnant, fucking Deku!"
He buries his cock deep as his knot pops fully, spurt after spurt of cum filling Izuku's belly.
They both collapse moments later in a sweaty pile of limbs.
Katsuki presses a tired kiss to the damp curls on top of Izuku's head, before releasing one last load of fluid inside him with a satisfied sigh. "Mine," he mumbles with a toothy grin.
