The quarantine has eliminated every other responsibility from my life so surprise !

a/b/o fic in which stubborn omega Ichigo ends up fighting annoying, attractive alpha Grimmjow in the middle of his heat.

The hall is empty when Ichigo bursts out into it, sneakers slamming against the tile and his backpack abandoned in his haste to get away from the classroom behind him. The door bangs open again with so much force the handle sticks in the wall, and a gale force of cerulean bloodlust absolutely obliterates the hallway behind the soul reaper.

Ichigo curses, head racing, heart thumping out of his chest as he skids around another corner.

Internally he's screaming his head off. First he woke up with a stomach ache, then there was a pop quiz in history, and then he found out he forgot his lunch—a visit from Las Noches' most pretentious espada mid-class just had to make it a perfect storm.

Three more doors until the exit, he tells himself. Three more doors and you can stop running.

The first set of doors are already open, leading to stairs that Ichigo flies down three at a time. He reaches the bottom—the second doorand doesn't instantly hear crackling energy behind him. Did he give up?

He cocks his head, listening, and almost jumps out of his skin when a crash shakes the hallway. It only takes a second to realize what happened—he jumped the fucking stairs—and Ichigo is back to sprinting for his life.

The soul reaper jars his wrists shoving the final set of doors open, bursting out into the deserted schoolyard. He sends a small thanks in the back of his mind to his high school's level of absolute obliviousness. A student could run from a lethal mass of energy across the whole campus without disturbing a single class. Being terrorized by an espada was some shit, but at least Ichigo never had to explain himself.

Speaking of the devil, the last set of doors are blown off their hinges when the storm comes through and materializes, scorching the grass as it takes the form of a man hurtling towards Ichigo at top speed.

The man, now identifiable as Grimmjow Jaegerjaquez, latches himself onto Ichigo's back and wraps himself around the soul reaper's body.

"Miss me, Kurosaki?!"

Ichigo takes a few steps before falling, eating dirt while Grimmjow clings to him like a baby possum. The espada doesn't let up, keeping Ichigo's body pinned with the position

"Well, did you?" The espada cocks his head as Ichigo struggles beneath him.

"I don't know Grimmjow," Ichigo wheezes. His stomach still hurts, and two hundred pounds of Grimmjow pressing against his abdomen isn't helping.

"Are you asking if I missed being chased across my whole school mid-class only to get ground into the soccer field by you? Let me think."

With an indignant thrust of his shoulders, Ichigo rolls Grimmjow off his back and scrambles to his feet. Trying to maintain his composure, he rifles through his pockets for his soul reaper badge. The espada watches, amused as Ichigo discards his human body off to the side once he finds it. Dusting his hands off, Ichigo sees the grin on Grimmjow's face and flips him off.

"Enjoying the view, asshole?"

"I just like the idea of two of you. Fighting me at the same time, maybe."

Grimmjow's grin widens.

"Preferably both of you in my lap."

Ichigo has twenty different curses he wants to hurl at the espada's lean face, but he opts for drawing his sword instead. That bastard will eat his words.

Grimmjow dodges a few swipes, draws his own weapon, and the dance begins. The two duck over and under one another, stepping gracefully between the air and the ground as their blades clash. Ichigo's stomach twangs again as they spar. He does his best to ignore it.

All of Ichigo's concentration is on the fight, his face quickly turning red from the strain of keeping up with Grimmjow. He must be out of shape. Since when did he start sweating so easily?

To make matters even more frustrating, Grimmjow looks totally at ease. He might as well be reading the paper with his free hand for all the fight Ichigo seems to be giving him.

You know why it's like this.

The thought slithers in, making Ichigo falter and miss a block. He's gouged across his ribs for his hesitation. Ichigo winces, putting some space between himself and the espada who won't stop eyeing his torso.

You know you weren't designed to win.

As if on cue, Grimmjow juts his chin at Ichigo and winks. Ichigo wants to tear the espada's face off or bury his own head in the ground from exasperation. Grimmjow was frustrating enough as himself, exuding crazy alpha energy in literally everything he did. He just had to be interested in Ichigo on top of it.

He could only hope Grimmjow hadn't noticed he was an omega, and the flirting was because the espada had nothing—or no one—better to do.

Why can't you be a good omega?

The soul reaper is brought back to earth when Grimmjow blows a kiss. Ichigo rolls his eyes. Actually, Grimmjow could probably care less about who or what he's fucking. He'd bet money Grimmjow could get it on with a broom if its bristles were orange.

The notion is so ridiculous it pulls Ichigo out of his potential thought spiral. The soul reaper grips his sword with renewed vigor, pushing his thoughts to the edge of his mind. All that matters is the task at hand: kicking the shit out of a certain pretentious, blue-haired bastard.

Now focused, Ichigo dodges two swipes, fakes a jab, and takes a chunk out of Grimmjow's left calf with a deft flick of his blade. For the first time this fight, the espada falters. Ichigo savors the look of surprise that flashes over his features.

"You ready to give up?" The taunt is only a half-joke; now that the action's paused, exhaustion is settling into Ichigo's body.

Instead of answering, the espada dips his free hand into the wound and splits his fingers on either side of his tongue, lapping the blood off out of the V they make.

Ichigo looks away almost immediately, praying Grimmjow didn't see him blush. Typical alpha behavior from a stupid, disgustingly attractive alpha. Even if Ichigo would rather eat paste than fuck Grimmjow, he can't stop a primal part of him from imagining that tongue between his legs.

The thought sends a pulse of unwarranted need through his body, and his stomach twangs again. Ichigo grits his teeth and lunges at Grimmjow once more.

He's going for Grimmjow's forearm when it happens. Ichigo isn't sure how to describe it. It's like something inside him just...snaps. One moment he's in the middle of a dive, and the next he's on his knees clutching his stomach, pain radiating from his torso in thick, hot waves.

"Uh, Kurosaki?"

Grimmjow's voice is faint amidst the ringing in his ears. Ichigo blinks. His vision is blurry.

While his body is still, Ichigo's mind is racing. It rattles off a list of potential causes as fast as he can think. There's no way it's from blood loss—he's been hurt worse in the past. Fatigue, maybe? He did skip lunch. Do human rules apply to spiritual bodies?

Another pang in his stomach derails his train of thought. The pressure is becoming unbearable. Ichigo presses his ribs to check if one's dislocated, and something trickles down his thigh.

And then a much worse possibility crosses his mind.

Horrified, Ichigo wracks his brain for the memory of taking his suppressants that month. What he recalls terrifies him even more: the pill on its way to his mouth when Grimmjow knocks on his window. Ichigo abandoning the prescription to kick his ass, and never coming back to take it.

Ichigo connects the dots and wishes he could melt into the ground. No wonder he'd felt sick and dizzy all morning; why Chad and Keigo wouldn't leave him alone.

He was in heat in the middle of a fight.

"Did I hit you too hard or something?"

Ichigo forces himself to look up and sees Grimmjow walking towards him. A flash of panic streaks through him, and he uses all the strength he can muster to scramble backwards. Every little movement sends more slick trickling down between his legs. Ichigo fights to hold back a whimper when a gush of it soaks the back of his pants.

"Why do you look so—oh."

Grimmjow's only a few feet away when he stops like he's been stabbed. Eyes lit up with an almost manic gaze, he takes a step back and then two steps forward.

"Oh my god. No way. It can't be."

With every step forward Grimmjow takes, Ichigo moves further backwards across the field, an arm still around his stomach as his mind yells to just submit already.

Ignoring the voice, he reaches where his sword has fallen and holds it up between them. Unfortunately, Grimmjow could care less about anything besides the omega. Batting the blade aside with ease, Grimmjow closes the gap and plants his palms on either side of Ichigo's head.

"Ichigo Kurosaki, an omega? I have to be dreaming. There's no way I'm living my biggest fantasy right now." The espada takes a long, deep inhale, a shiver running through his body.

"Fuck off," Ichigo snarls. He tries to move backwards, but Grimmjow holds him in place by the front of his robes.

Another gush of slick makes its way down his legs and Ichigo wants to scream. There has to be acosmic rule against your worst enemy being sinfully attractive, being attracted to you, and being an omega when they're an alpha all at the same time.

Grimmjow bites the shell of his ear, and for a second Ichigo's frozen, focusing too much on not giving in to his biology to stop the alpha's advances. He whimpers as Grimmjow's tongue flicks over his lobe, the espada purring as he takes in the sweet taste of Ichigo's skin.

Grimmjow angles his head downwards—scenting him—and the distance from Grimmjow's scent glands is enough to snap him from his trance. The soul reaper punches Grimmjow right in his perfect jawline, using both his feet to kick the alpha off of him. Grimmjow rears backwards and Ichigo tackles him, wrestling him back to the ground.

The fight is much less graceful than before. Ichigo and Grimmjow scrabble in the dirt as they claw at the other's faces, snarling and, in Ichigo's case, muttering a constant stream of curses to avoid being overwhelmed by the alpha's proximity.

"I always imagined it that I'd find you dripping wet like this," Grimmjow pants as he muscles out of a hasty chokehold. Ichigo gasps as Grimmjow elbows him in the ribs.

"You would've been in heat for hours—" He's cut off by a kick that sends him rolling.

Ichigo doesn't let up for a second, grappling with the espada as soon as he stops moving. He doesn't want to admit it, but wrestling and getting the alpha's scent all over him is actually helping with the head in his stomach. What it isn't helping, however, is the independent problem of how much Ichigo wants to sink his teeth into the thick meat of Grimmjow's neck.

Grimmjow pulls Ichigo's head back by his hair, catching him off-guard and making him keen. The alpha grins at the noise, taking the opportunity to finish his sentence.

"—too stubborn to ask an alpha to fuck you."

Ichigo pants for a second in Grimmjow's grip. The strain of overpowering the larger man is catching up to him. At least he's in-character in Grimmjow's fantasies; he'd die before he spread his legs for some overconfident alpha's knot.

Grimmjow tugs his hair again, and this time Ichigo wrenches his head free. His mind goes back to technicalities as they fight, distracting from the need that is slowly consuming his body. Ichigo needs to end this soon, which means he has to incapacitate Grimmjow or knock him out.

A choke from behind wouldn't work; Ichigo's light enough that Grimmjow could flip him over his shoulders. And Grimmjow's head? Between his thighs? Leg holds were out of the question. What Ichigo ends up on is classic strangulation: get Grimmjow on his back, get his hands around Grimmjow's throat, and don't let go no matter what.

The soul reaper winces at how fucking terrible the idea is, but he doesn't have many options. Grimmjow misses a jab at his stomach and Ichigo takes the opportunity to execute his plan.

Kneeing the alpha in the side, Ichigo takes advantage of the imbalance to roll Grimmjow onto his back. Sparing no time, he latches onto Grimmjow in a straddle, wrapping both hands around his neck and putting all his weight into the choke.

It works—it works!—and the espada is pinned by Ichigo's hold. Ichigo's mind is riding a triumphant adrenaline high until a weight on his sides makes him realize the mistake he's made. Grimmjow's hands are where the omega's thighs meet his hips, and the alpha is pressing Ichigo right down into his lap.

"Come on Kurosaki," Grimmjow chokes out, eyes hungry.

"You know what we both want."

He punctuates "want" with a roll of his hips, grinding himself up against Ichigo as he kept him from moving away.

"I—you—" Ichigo can't hold back a long whine as Grimmjow ruts against him again.

All his effort goes into keeping Grimmjow from getting up, and the two end up locked together, Grimmjow by his neck and Ichigo by his hips.

Grimmjow coughs, trying unsuccessfully to throw Ichigo off of him. Ichigo knows he's close to passing out, even with the fingers digging into his thighs.

He stares at the alpha's reddened, panting face and realizes how much he fucking loves having Grimmjow at his mercy like this. Twisting his fingers, he marvels at how Grimmjow twists with them.

"Help me...help you."

Ichigo flinches at the pure need in the alpha's voice as he chokes out the words. Fuck. He shouldn't be staring this hard at Grimmjow right now. Yet, he can't stop staring; he's picking up a new, softer emotion in the espada's heated gaze. Is Grimmjow...submitting?

Suddenly, Ichigo realizes just how badly the alpha wants him, and as a wave of arousal pulses through his body, fuck it—when in Rome—Ichigo catches Grimmjow's mouth in a brutal, passionate kiss.

The espada reacts almost immediately, kissing him back and sucking Ichigo's bottom lip into his mouth. Ichigo relaxes his grip but keeps his hands on Grimmjow's neck, tightening his grip when Grimmjow tries to move them off. It's an instinctual response, but the noise Grimmjow makes as Ichigo's fingers dig into his throat gives the soul reaper an idea.

"Hands by your sides. If you want this, you're gonna have to obey me."

To his surprise, Grimmjow follows the orders, lying his hands by his sides with nothing more than a shiver. Ichigo tilts his chin up with one finger so their eyes are forced to meet. Grimmjow's clearly annoyed by the command, but even clearer is the desire that saturates his gaze. He doesn't have to speak for Ichigo to understand that the alpha will do whatever he asks.

Ichigo grins at the realization. Good alpha.

Keeping one hand on Grimmjow's throat, Ichigo trails the other down the espada's bare chest, tracing each sinewy curve with agonizing slowness. Grimmjow's more sensitive than he's expecting. Each touch makes the alpha jerk upwards, choking himself in Ichigo's firm hold. He moves so much Ichigo wonders if he's doing it on purpose. A tensing of his fingers followed by a quiet groan confirms his suspicions.

The espada's reactions are amusing, but Ichigo's still leaking hard, his slick soaking through both of their pants at this point. He's so horny he could barely keep from falling on his knees and presenting, but he'd be damned if he lost this opportunity. He was going to enjoy this.

Arching his back, Ichigo begins to move his mouth with his hands, his lips ghosting over one of Grimmjow's nipples as his free hand tweaks the other. If the espada wasn't being held down, Ichigo is sure he would've jumped. He smirks.

"That feel good?"

Grimmjow lets out a murmur that Ichigo takes as a yes. Pressing his tongue flat against the espada's nipple, Ichigo slowly draws his mouth across it, the texture of his tongue to create an intense friction on the sensitive area. He pinches Grimmjow's other nipple to round out the sensation, the alpha twisting beneath him from the mix of pain and pleasure.

"Ah, fuck!"

Ichigo feels Grimmjow's hands touch his shoulders before they snap back to the ground, clenching into tight fists as Grimmjow bites his lip but doesn't try to stop the omega. Mouth still on Grimmjow's nipple, Ichigo moans, letting up on the pain for a second as a reward for the obedience. Seeing Grimmjow like this was absolutely fucking perfect: in spite of his heat it was the alpha coming to pieces beneath his hands.

Swiping at his nipples a few more times, Ichigo moves down the espada, taking extra care to find each and every one of Grimmjow's vulnerable places(which, judging by Grimmjow's reactions, seem to be fucking everywhere).

The omega reaches the seam of Grimmjow's pants after what feels like hours of running his fingers and mouth over the espada's heaving chest. Ichigo's trying to maintain his composure, but he's almost as desperate as Grimmjow—every move Grimmjow was making grinded the alpha's dripping cock into his entrance, the tip just barely restrained by the fabric of their robes.

He's enjoying Grimmjow's helplessness, but Ichigo is so, so wet. The alpha's squirming just makes him want him more.

Grimmjow lets out a high-pitched moan as Ichigo traces his fingers over the waistline of his hakama, rubbing at the sensitive skin between his stomach and his groin. He moves just enough for his hand to slip between their laps, and Grimmjow's eyes roll back as Ichigo grinds his palm down firmly against the alpha's cock.

"Kurosaki…"

Ichigo pretends not to hear him, pressing against it once more before moving away and leaving Grimmjow's hips bucking up into empty air.

The alpha whimpers at the loss of friction, the genuine distress in his voice catching Ichigo off guard.

Ichigo shudders, but he isn't done yet. He wraps his hand around his own erect member, jerking himself off through his clothing as he grinds back down on Grimmjow's cock.

It's a deliciously agonizing feeling, just a couple layers of cloth holding them back from fucking with just barely not enough friction to cum. Grimmjow is in agony—delirious from need, it's clearly taking all of his willpower to keep his hands down by his sides.

Ichigo hasn't seen him in this much pain from being stabbed. He imagines how Grimmjow must feel, being teased with hot, wet streaks of pleasure, completely helpless in Ichigo's hands. He's probably more desperate than Ichigo is to be fucked right now.

The thought sends another gush of slick down his robes. He could almost get off from watching the alpha squirm.

Almost. He still has to make the alpha eat his words. Running through his train of thought gives Ichigo another idea.

"I want to hear you beg," the soul reaper murmurs, leaning in close so his voice travels directly into Grimmjow's ear.

"I want you to beg to knot me. Beg me like an omega." On the word omega Ichigo winds a hand into Grimmjow's hair and pulls, making the espada hiss.

"I want to hear how bad you want this or I'm going to leave."

Grimmjow's past coherent words. All he can respond with is a noise of equal parts indignation and distress. He tries once again to unseat Ichigo but the soul reaper holds him fast.

"Do that again and I'm leaving."

His voice is harsh. The alpha whimpers again but doesn't repeat the action. They sit in intense silence for a few moments, Ichigo grinding against Grimmjow's lap with calculated, methodical circles that rub his hole all over the head of Grimmjow's throbbing cock.

It takes what feels like forever, but finally Ichigo hears it:

"Please."

The voice is so faint he almost misses it.

"What was that?"

"Please let me knot you."

"Oh come on. I know you can beg better than that." Ichigo traces his finger over Grimmjow's trembling jaw.

"Please! I've done everything you wanted!"

The volume of Grimmjow's voice surprises the omega, hitting a pitch that almost sounds like a wail. Grimmjow doesn't even seem to notice, his eyes screwed shut as his hands dig into the ground to resist touching Ichigo. Something seizes in the espada's chest, and his next words are even softer than before.

"I want you so fucking bad."

Grimmjow doesn't need to be any louder. Ichigo is undoing his robes before the words leave his mouth. He pulls Grimmjow's pants down just enough to expose his member, the thick erection bouncing up out of his clothes. Ichigo licks his lips; Grimmjow is even bigger than he's expecting, the alpha's cock red and swollen with precum.

The omega wastes no time with further teasing. For once, he agrees with his instincts: Ichigo needs to be fucked now. Spreading his hole with his hands, Ichigo sinks all the way down on Grimmjow's cock in one smooth movement.

Both of them let out huge moans, relief hitting them like a cold shower after a month in the desert. The sensation of being filled along with Grimmjow's look of absolute euphoria almost makes Ichigo come—he wraps his hand tight around the base of his cock to stop himself.

Once Ichigo is sure he won't come early, he lifts his hips and slams himself down hard on Grimmjow's member. Bracing his weight against Grimmjow's chest, he sets a fast pace, the alpha is trapped beneath him as he rides his cock.

The pleasure is almost overwhelming. Every time Ichigo comes down on Grimmjow he feels the alpha's cock pulse inside him. The angle is just right, every thrust filling him up completely while rubbing the head of his cock against Grimmjow's stomach. Ichigo loses himself like this, giddy from the endorphins shooting through his brain.

After a few minutes of bouncing up and down on Grimmjow like an animal, Ichigo realizes the alpha's trying to get his attention and comes back to earth. He stops riding him but doesn't stop moving, sliding down to the base of Grimmjow's cock and jerking his hips while it's inside of him, rubbing Grimmjow's cock on his prostate in soft taps.

"What? Want me to stop?"

"I—" Grimmjow is panting, drenched in sweat and Ichigo's precome. He tries again to speak.

"Let me—fuck you."

It's a stilted sentence, but Ichigo understands it nonetheless. Tracing a finger over Grimmjow's nipple he pretends to think.

"Well, you have been good…"

But the alpha has had enough of being submissive. Grabbing Ichigo by the hips, he rears up and flips them. Ichigo is on his back beneath the alpha, his legs up still around Grimmjow's waist and Grimmjow's cock still inside him. Before he has a chance to react, Grimmjow begins pounding into him.

Grimmjow was breaking the rules but Ichigo could care less—every thrust of the alpha's cock was dragging hard against his prostate, lighting up his groin with streaks of white-hot pleasure. This was the kind of sex his omega side was longing for: being fucked raw and senseless by an alpha who took charge.

Going limp, Ichigo let Grimmjow use him like a toy, the same way he had used him before. Knowing that he had done it first, that he had done that to an alpha, made the dynamic feel different. Instead of submitting to Grimmjow, he was handing over control.

They feel Grimmjow's knot form at the same time. Ichigo lets out a shocked moan when it catches on the rim of his hole, the added girth forcing Grimmjow's cock even deeper inside of him. The omega's on cloud nine right now, the cocktail of pheromones and residual need sending Ichigo on a high that pushed his sensitivity up to eleven.

Grimmjow begins to pull out, and Ichigo clamps his legs around the alpha to hold him in place. He's too fucked up for words but Grimmjow understands him anyways. Hands still on Ichigo's hips, Grimmjow sets a new pace, switching from long strokes to short ones that jackhammer his cock in and out of the wet omega.

Neither of them last much longer in the new, frenzied cadence. Grimmjow howls as he comes, forcing his knot as far as it can go into Ichigo's tight hole. Ichigo feels every pulse of the alpha's orgasm, Grimmjow's knot throbbing directly against his prostate and forcing out an orgasm of his own. He moans, cum shooting all over his and Grimmjow's chests.

Exhausted, the two collapse against each other. Grimmjow's knot automatically pulls Ichigo to his chest, where the omega trails his nails over his skin.

It takes a bit, but eventually Ichigo gains enough energy to speak.

"Have you...ever done something like that before?"

To his surprise, Grimmjow's quick to respond.

"No."

Ichigo grins and kisses the underside of the alpha's jaw.

"So that means I must be special." He hasn't done something like this either, but Grimmjow is way too deep in a post-knot haze to question him.

Grimmjow huffs, as if only now remembering his rebelliousness. Carding his fingers through Ichigo's hair, he tangles his hand in the sweat-soaked orange locks.

"It means you're a fucking bastard."

Then, more quietly:

"And that we have to do that again."

The alpha is almost demure when he says it, and Ichigo can feel him blushing. The omega grins, reaching up to twine a hand of his own in Grimmjow's hair, savoring how the alpha still shudders.

He doesn't think he'll have a problem with that.

Anyways Ichigo is a really angry power bottom and you can't convince me otherwise

Thank you all for waiting so long! I hope it was worth it :")
