The curse was supposed to turn him into a full blown dog, but of course his Minamoto blood works against, or according, to his favour. Depends on how people look at it.
Most people would say, oh, glad I didn't get turned into a mutt. While Kou, isn't so sure if he should be glad he has a pair of doggy ears and a tail that won't stay still with the rest of his body being very human.
At least it got him attention from Yashiro senpai. The girl patted his head and scratched behind his ear for a full minute and Kou couldn't stop his tail from wagging even if he tried. His happiness didn't last long when a familiar presence looms over their heads and sudden a whole Hanako is right in between him and Yashiro senpai.
The moment Hanako puts his smarmy hands on him, touches venturing down his belly mentioning something about 'neutering pets', heat coiled inside Kou's stomach because his body felt much, much more sensitive than he remembered. The last thing he heard from the ghost is him drawling a 'bad boy!'' at a retreating Kou, running away from the girls' toilet.
The only place Kou has in mind is the student council room and he hopes its not locked. It doesn't even matter if Aoi senpai sees him like this, he just needs to find Teru-nii to protect him from Hanako.
The door is unlocked and Kou steps inside to see his brother's broad back, the light from the window almost makes him look angelic. He's typing away on his laptop and Kou looks around to see no sign of the vice president inside.
"Teru-nii," he calls out. "I'm in trouble."
When Teru turns around to finally see him, his older brother chuckles softly and immediately closes his laptop. Teru walks over to Kou with kind eyes then locks the door behind him. "Was it the ghost's fault?" His eyes change when he asks, "Do I need to kill him?"
Panicked, Kou convinces his brother, "It's--it's my fault! I tried to protect senpai and got hit instead of her!"
Taking a hold of Kou's shoulders, Teru walks him over to his table with a unconvinced hum. "The ghost didn't help, anyway, right?"
"He always helps." Kou looks down to his shuffling feet. "He's just being an ass right now."
"Alright." Teru sighs and turns him around bodily. "Guess we're going home a bit late today."
"Are you mad?" Kou asks, eyes wide, not knowing it's quite impossible for Teru to be mad at him when he gives him the puppy eyes. Now, the look is complete with a set of ears and a tail. His little brother is trouble.
Teru finally takes a good look at his brother. The orange ears on top of his head is almost flat from where it falls with disappointment. The tail behind him drooping the same way.
There's not much change to Kou's face. A tongue darts out to wet his dry lips then he chews on it nervously. His already sharp canines did help to complete the look though.
Honestly, Teru didn't think it was possible for Kou to look more of a puppy than he already did. Didn't think Kou could be even more obedient, more dependant, more--
"Nii-chan!"
Teru blinks out of his thoughts and looks down to see Kou hiding his red face behind his hands. Kou whines, "Stop doing that."
Oh. Teru finally catches himself touching and thumbing Kou's ears without realising. He bends slightly to Kou's level and tilts his head to the side. "Did you get more sensitive?"
Teru asks it so innocently. So nicely, Kou didn't think of any implications behind that question. He nods slightly and suddenly he finds himself in Teru's arms. "Wha--"
"Is this sensitive?" Teru asks as he holds Kou's tail gently behind him, one arm wrapped around his waist to keep him close.
"Just the bottom part," murmurs Kou, voice muffled from where he's hiding his face in Teru's chest and shivers when his brother's hand strokes lower until he reaches the part of the tail that connects to his body. Kou finally understands where this is going and it makes him giddy, just a little. But mostly nervous because they're still in the student council room. But Teru-nii did lock the door already.
Kou tilts his head up to brush his lips against Teru's. "You seem to like this a lot," Kou murmurs and he feels, rather than see, Teru's lips curling into a smile.
"I only like it because it's you."
Teru crowds Kou towards the table and blindly pushes away the pen and paper there. After seating Kou on top of the table, Teru settles comfortably between his brother's spread legs.
Their mouths meet for a soft kiss making Kou grin in delight. Kou cups his brother's face with both hands and meets the next press of their lips. While Teru makes quick work into pulling out Kou's tucked shirt and unbuttoning it, their kissing gets increasingly messier.
Teru swallows Kou's gasps and whines when the he splays his palm on Kou's abdomen. Kou blames it on his heightened senses when he gets embarrassingly desperate, tail wagging wildly just by getting his stomach teased.
Kou lets out a surprised 'ah!' when Teru grabs a hold of his tail and it's not fair how much advantage Teru has over him now. Well, more than usual.
With one hand propped on the table to support himself, Kou tightly holds onto Teru's wrist with the other. He's basically pinned on the table and groans appreciatively when Teru finally rocks his hips forward.
If Teru wasn't muffling Kou's noises, he would've missed the sound of the door unlocking. But even if he didn't, there's really little Teru could do to stop Akane from walking into the room when he originally held the spare key.
This is new. Akane has always known Teru's weird attachment to his siblings. It's as bad as Akane's own with Ao-chan and that's saying something. But this sight makes an almost sadistic laugh bubble inside Akane. Of course--the perfect, intelligent student council president. Loved by everyone, but only loves his own siblings.
But the kiss lasts too long to be more than a cute peck between siblings. Akane's questions are answered when Teru flicks his eyes up to look straight into Akane's eyes and almost makes a show out of licking into his brother's mouth. Just to unnerve Akane.
"Wonder what your fans would say, president." And the trash speaks, without even closing the door first. He's dead the moment Teru is done with the squirming pup pinned under him.
Teru's unfazed when he pulls his mouth away from Kou's, a string of saliva breaks between them and it makes the usual pristine student council president look messy, for once. Leaning back, Teru throws Akane a practiced smile. Charming to most people, but anyone who has known Teru's real nature would find it threatening. "You're here early."
"Thought I could start on my work first," Akane says lowly as he moves to close the door behind him and the 'click' from the door lock sounds sharp. "Didn't know you already made yourself busy."
Shushing his whimpering brother, Teru drops his smile when he turns to look at Akane again. "Any reason you're still here? A death wish maybe?"
He sees the way Akane has to drag his gaze from Kou's flushed red face, ears twitching and mouth wet, to catch Teru's warning look.
He coughs into his hand awkwardly. "Can't pass up a good blackmail material, can I?"
"Hm? Interested to watch me fuck my brother?" Teru ducks to press his lips against Kou's neck, eyes flickering towards Akane. "Does your Ao-chan know you're an exhibitionist? I could definitely give you one hell of a show wit--"
"Shut the fuck up," spits Akane. He's positively pissed now and it makes Teru feel like he's winning, just a little.
"Then do me a favour and scram. My baby brother needs me right now," Teru emphases it by running his hand under Kou's shirt, thumbing the skin there and grazing at a nipple to hear his brother's cute whining.
Akane lets out an exasperated sigh. "Calm down. I'm only here for the files."
He knows Akane could see them within his peripheral vision, while he rummages the shelf. Kou is aware of the things Teru does to Akane in the student council room. Not the exact details because Teru said he gets a bit mean with Akane.
Because with Akane it's stress relief, as Teru-nii says it, and with Kou it's real love. Now, Kou isn't the type to be jealous, but it did catch Teru off guard when his brother raises his hips to grind his crotch against Teru's and muffles his moan by biting his fist.
"Don't be impatient," Teru murmurs into Kou's ears then bites lightly at the tip. Despite saying that, Teru can't help but to press the heel of his palm to the outline of Kou's erection. After all, he can't leave his brother hanging.
Kou is surprisingly shameless at showing off like this. He's proud of almost anything his older brother does, anyway. If arching his back shows that Teru-nii is treating him good then he'll be slut about it.
Something falls to the floor, then a few fumbling and muttered curses later the door creaks open and then immediately slammed shut. The brothers share a look with one another and can't help themselves from bursting into laughter.
Teru nips at his brother's jaw. "Pretty bold today, I see."
"You talked to him as if I wasn't here." Kou hides his face into the crook of Teru's neck. He doesn't wanna look like he's sulking so he wraps a leg around his brother's thigh, urging him to continue.
"Is that so?"
Teru threads his fingers through Kou's hair, petting and scratching behind his ears for a while until Kou starts wagging his tail again. Teru smiles. Cute.
"Kou," calls Teru as he tugs on strands of Kou's hair to pull his head back. When Teru holds his hand in front of Kou's face, the younger instinctively opens his mouth to suck on his brother's slender fingers. Now that he's basically a dog, Kou feels like he's slobbering on his brother's hand instead. It feels entirely unsexy but when Teru hums and tells him, "good boy," it makes Kou work harder, drool probably onto his chin now.
In the mean time, Teru manages to pop their trousers open and Kou moans when his weeping cock finally, finally gets attention. Teru-nii's length is warm and hard against his and Kou hears Teru-nii's pleased sigh when Kou grasps his cock lightly, just to press his brother's into his own hardness. His brother rotates his hips, tip of his cock sliding from Kou's balls then back to line their cocks together. Kou wonders if Teru would ever fuck him in this room one day.
But for now, with a final lick of Kou's tongue, Teru removes his fingers from his brother's mouth and uses that hand to wrap his slender fingers around both of their cocks. It's just wet enough for his hand to slide over their cocks comfortably. Now without Teru's fingers, Kou's mouth feels entirely too empty. He could barely muffle his own moans when Teru cants his hips up, hand tightening, with the other gripping Kou's tail near the root.
"Nii-chan," gasps Kou before Teru presses his mouth against his brother's and licks into him, swallowing his noises. Kou's 'ah's just sounding like muffled whines. When he comes, Kou throws his head back, and all other noises are drowned by his moans and gasps. There should be no one nearby to hear them at this hour, at least, Teru hopes so.
Kou's panting turns to whines after a while from his overstimulated cock. Teru finally takes pity and lets him go, Kou completely laying on the table now. Fully wrapping his hand around his own length, Teru takes in the sight of his debauched brother, pants down his knees and school shirt pushed up to expose his dirtied belly.
Honestly, Teru knows he should be ashamed in himself. He knows he shouldn't be taking perverse pleasure in his little brother's big eyes staring at him with adoration, clumsy hands reaching down, trying to help his older brother release on his spent body. But Teru still gasps out Kou's name over and over, telling him, "Such a good boy, you're so good." And Teru finally comes, adding the mess onto his brother's lean stomach.
Supporting himself with an hand beside his brother's head, Teru only needs to hold his cum stained hand in front of Kou for him to immediately open his mouth and lick the fingers clean as if he was made for it. Maybe he was. He is Teru's perfect little brother.

It's when they finally cleaned up, Teru tugging Kou's clothing in place when he suddenly remembers something.
"Kou, can you say 'woof' for me, once?"
Kou feels his face heat up at the request. He wants to say no, knowing his brother is just trying to mess with him but then Kou sees the way Teru's eyes sparkle.
Letting his gaze fall, Kou's ears twitch once, twice in embarrassment then he quietly lets out, "W-woof."
Teru laughs earnestly, covering his face with a hand. He's still chuckling in between his words when says, "You're so cute, Kou." Sure, Kou has heard it hundreds of times before but it still makes him red in the face.
After Teru finally collects himself, he ruffles Kou's hair affectionately.
"Now lets go find the ghost and turn you back, yeah?"
