Wakatoshi’s self-control is slipping, and Tooru is to blame.

“Toshi-nii, you feel so /good/,” Tooru moans as he rolls his hips in fervent, fluid motions that have the older alpha groaning.

Here’s the thing. Wakatoshi had always been protective of Tooru. When they were younger, he found himself playing the part of the knight in shining armor, even when Tooru himself was no delicate princeling and was capable of fighting (and starting) his own battles.

It didn’t matter that Tooru had an older sister who was just as protective. Wakatoshi made it his job to make sure Tooru was happy and unharmed.

So being the one responsible for Tooru’s undoing, even if it is in the context of sex, is a novelty that Wakatoshi is still getting used to.

That doesn’t mean he doesn’t enjoy it, though.

“You have such a filthy mouth, Tooru.”

Fingers dig into the supple flesh of the young omega’s ass, his own cock thickening when Tooru shivers with delight before fucking himself harder and faster onto Wakatoshi’s cock. He’s still so tight around Wakatoshi, even with how often they fuck,

and the idea that Tooru might continue to grip him this well years down the line is one that excites both Wakatoshi and his alpha.

“You /like/ it,” Tooru counters, the little minx, “I know you do. I can feel your cock move inside me.”

Wakatoshi doesn’t remark upon Tooru’s own cock spilling precum on both their abdomens, pink and hard and hungry for friction, twitching in time with the tightening of Tooru’s walls. Tooru had only just cum, but he’s already raring for another climax.

Greedy, greedy omega.

But Wakatoshi isn’t one to talk, is he? It was greed that tempted him into Tooru’s bedroom when the rest of the Oikawas were away. Greed that had him cumming inside Tooru after fucking him raw, all but knotting and claiming Tooru for himself.

And it’s greed that has him driving his cock into Tooru’s puckered hole, already puffy from their first round, wet and glistening from Tooru’s slick and Wakatoshi’s load.

Wakatoshi may not be inherently greedy, but when it comes to Tooru, he’s insatiable.

“Tooru,” Wakatoshi growls.

His knot is growing steadily alongside the sweetening of Tooru’s scent, obviously pleased with this development. The omega shamelessly moans every time his rim kisses the beginnings of the alpha’s knot, eager to take it in, eager to make it /bigger./

He has never spent his rut with anyone before, much less the love of his life. There’s no saying what his alpha will be capable of doing after his knot brings them together and this feverish haze finally overcomes him.

But Tooru doesn’t care, and Wakatoshi had selfishly hoped that he wouldn’t.

Greedy, greedy omega.

Wakatoshi pulls out of Tooru completely, and before he even has a chance to whine like Wakatoshi is sure he would, Wakatoshi maneuvers them so that they’re laying side by side.

“This will be easier on you later,” he explains as he slides home, inch by delicious inch, back into Tooru’s tight, wet heat. Tooru keens when Wakatoshi bottoms out, fingers reaching for the knot that sits just outside of where they’re joined.

“I want it, Toshi-nii,” Tooru whispers as he begins to move his hips back and forth, meeting Wakatoshi pound for pound, making up for what he lacks in grace and skill with stamina and strength. “I’ve wanted this for so long.”

Tooru starts babbling, then. About how he’s wanted this since he first learned to pleasure himself. About how he’s opened himself up with fingers, with toys, to thoughts of Wakatoshi—the boy who always protected him, always within reach, always reliable.

The perfect alpha.

A primal ache pulses through Wakatoshi knowing that he is the cause of Tooru’s unraveling, and the honesty that was lacking before during their first tryst he now finds in abundance. In words, and in brown eyes, tearful and dark from arousal.

He buries his nose into the curve of Tooru’s neck, delighting in the scent of nearly ripened peaches, something liminal, almost like an omega on the cusp of heat. All the while, the head of his cock presses against the spot that makes Tooru’s back arch into a beautiful curve.

“I want to be your omega, Toshi-nii,” Tooru says, desperate and so far gone, head lolling to the side as Wakatoshi ravages his neck with love bites that aren’t quite enough to appease his omega. “Be my alpha.”

“In time, Tooru. In time,” the alpha reassures as he tempers his growls. The thought of Tooru—sweet and sensual and slender Tooru—plump with his cum while round with his pups is almost too much for him to bear.

Wakatoshi’s thrusts pick up in pace, erratic now that he’s inching closer and closer to his climax. The sound of their hips meeting fills the air. His cock pushes in and out of Tooru’s hole with an obscene squelch, so wet it’s as though Tooru had a cunt. It’s music to his ears.

“Tooru—”

“Inside,” Tooru demands, tone petulant and firm. “You know I want it inside, so give it to me—ah—!”

Wakatoshi pushes his knot into Tooru with no further warning, locking them in place as he sends them both over the edge, releasing load after load into Tooru’s loose and willing body.

“Yes,” Tooru cries. “Yes, yes, yes. Breed me, /breed me./”

Wakatoshi kisses Tooru as he fucks the younger omega through their orgasms. Tooru’s mouth parts, and their tongues slide wetly and languidly in time with the aborted movements of Wakatoshi’s hips, limited by the locking of his knot.

By the time Wakatoshi’s cock had stopped filling Tooru with cum, Tooru’s flat abdomen had gotten just a little soft from Wakatoshi’s seed. The sight of it rouses a sense of satisfaction in both of them, more animal than human. To breed, and to be bred.

“Have I hurt you?” Wakatoshi finally asks when they break apart. His eyes flit all over Tooru’s body before Tooru’s hand cups his cheek.

“Toshi-nii,” Tooru admonishes, even as the warmth of affection spreads in his chest. “I’m not fragile.

“I know,” Wakatoshi says as he plants a kiss on Tooru’s neck, right where he will one day claim Tooru as his omega. He smiles. “Force of habit. It has always been my responsibility to keep you safe.”

“With you, I /am/ safe,” Tooru says with a smile of his own, not quite pure, fully aware of how much his words will please the alpha. An alpha’s primary duty is to provide and protect their mate, after all.

Wakatoshi chuckles despite himself, thinking about the tender emotion that has made a home for itself in Wakatoshi’s heart.

Oh, the things he is willing to do for Tooru.

When Wakatoshi’s knot goes down enough that they can move, Tooru resumes his position on top of his alpha, still full of Wakatoshi’s cock, still full of Wakatoshi’s cum.

“Again?” Tooru asks. His devilish smirk is like a siren’s call.

Wakatoshi answers with a smile. “Again.”
