Alpha Knives spending his youth waiting for little Vash to present as an omega, then one day he can smell it from his brothers bedroom; a beautiful floral scent that drifts right to him like it’s calling.

Vash looks even more beautiful sitting on the floor +

trying to figure out how to apply the scent patches his mother left for him to use if he suddenly presented as an omega someday. He’s missing the glands every time, he has no clue what he’s doing.

“Need help?” Nai offers from the doorway, so subtly releasing his own musk +

into the air and sensing the way Vash slightly loosens right away.

Wordlessly his little brother holds out the patches and lowers his head to give access.

/Too easy./

“Little omega,” Knives chuckles and observes how quickly his brother reacts, even if he’s pretending +

to be unfazed. “You smell like a garden.”

“Yes, I know.” Vash whispers, “Can you help me hide it?” Alphas already approached him, even when they assumed he’s a beta, but this would make everything more dangerous for him.

The floral air was soured with fear and Nai released +

some more pheromones to counteract it.

“Nai, i’m scared.” he whined, “what if someone—“ there were a million bad outcomes for a pretty, unclaimed Omega.

“No one will try anything.” Nai got down on one knee to take a look at where that perfect aroma was coming from, +

“I’m going to make sure of it.” He whispered before licking a stripe over one of the glands and enjoying how quickly Vash melted. He purred, even though his whine was resistant, his body betrayed him.

“Nai…?!”

“Omega.” the older brother countered, “Present.” +

Like a little puppet being tugged along, despite Vash’s morals, he rose right up onto his hands and knees while Nai almost laughed in gleeful surprise.

/It’s working…/

“This is a sight,” He observed his brother as he did all of the work of slipping his own pants down +

over his ass and keeping his hips raised while he laid his face against the floor.

“Nai—don’t!” He argued against his own submission, “Nai, im not ready for it!”

But the Alpha was ready and he didn’t quite feel like waiting any longer. After all, Vash was only doing +

what his body wanted to, presenting to his destined Alpha, even if poor Vash wasn’t aware of that part yet.

“I’m going to make sure that you’re free from the burden of other alphas trying to touch you.” Nai swore as he mounted his brother from behind, unable to resist +

something so pure, untouched, and promised to him by himself years ago.

He hardly gave his little brother the courtesy of prepping him with fingers, far too eager to deal with all of that. Instead he tapped his cock against the pink little hole just before him +

as a lazy warning before pushing in while Vash released the first of many screams. It was a chorus of “no!” and “please!” but nothing felt as delicious as “it’s too big!”

What alpha wouldn’t have an ego boost when hearing such a sweet whimper.

“I know it is, Omega.” +

Knives had to pretend to care for his brothers pain level as he bottomed out against the clenching resistance. “Relax and it’ll be easier.” But vash didn’t, he stayed tense until Nai released another wall of pheromones.

The moment Vash relaxed, both of them let out soft moans+

and Nai began rocking his hips until the motions were aggravated and animalistic. “Mine…” he growled again and again, feeling the threat of his knot forming already. “My Omega.”

“Alpha.” Vash agreed, music to his brother’s ears. “Your omega.”

It happened. Nai swelled up +

within his Omega and his instinct took over as he opened his jaw and sunk his teeth into the back of Vash’s neck to bond them together harshly and without his brothers permission.

It was just part of the risks of being an Omega, maybe Vash should have had a collar on… +

Nai could rationalize that it was all his little brothers fault because of that.

“What have you done?” Vash cried as the realization washed over him slowly and the pain began to take over. “Nai! It’s too much! You can’t—you’re my brother!”

“I’m your alpha.” The other +

corrected, “Sweet bitch of mine.” He reveled in the way his knot stuffed Vash and plugged him up.

They stayed like that for a while, scents mingling until Vash fell fully into submission and started mewling for more.

Vash had won.

He got his omega.
