"Katsuki was holed up in his house, trying to wait out the intense rut that had taken over. It wasn’t the first time he had waited it out, but he realized this time he was struggling as his nose picked up a scent that drove him wild. He followed it and found a bag you had left with some clothes, and his eyes dilated, body overcome with intense need." "He texted you, asking you to come by, which you happily accepted, unaware of his condition. You walked through the door, where he immediately pinned you to the floor, half naked and sweating, face buried in the crook of your neck." “Fuck, you really do smell so good. I need you now. I can’t fucking hold back.”

"Katsuki looks up at you, noticing the sudden shift in your scent. He smirks and runs a hand through his spiky hair." "Looks like my rut has affected you too, darling. Don't worry, I'll take care of you." "He presses his lips to your neck, inhaling deeply." <The air is thick with Katsuki's pheromones, which smell like a warm campfire in the woods. The room is dimly lit, with the only light coming from a few flickering candles placed around the room.> "His grip on you tightens as his desire and need intensify. His primal instincts are taking over, and he can think of nothing but claiming and satisfying you." "So tell me, Daniel, are you ready for what's about to happen?"

"Katsuki's eyes light up at your response. He smirks again and tightens his grip on you." "That's right, you're mine. Don't forget it," "he growls into your ear." "He flips you over so that you're lying on your back, his muscular body hovering over you. He leans down to capture your lips in a passionate kiss, his tongue exploring your mouth hungrily." "You can feel the heat emanating from his body, making your own temperature rise. The smell of his rut is potent, driving you wild with desire." "As he pulls away from the kiss, he stares into your eyes, his own filled with an intense hunger and need." "I'm going to mark you as mine, Daniel. Are you ready for that?"

"Katsuki's eyes glitter with triumph at your admission. He positions himself over you, one hand gripping your hip tightly as his other hand reaches up to brush away the hair from your neck. Then he leans in and bites down hard, marking you as his own." "As he pulls back, he looks at the mark with satisfaction before leaning in to whisper in your ear." "Good, because I'm going to claim you properly." "He begins to press kisses down your neck, murmuring the whole time about how good you smell and how much he wants you." <The atmosphere is electric with tension and desire. In the dim candlelight, your body is illuminated and Katsuki's eyes are focused fully on you. The air is heavy with the musky aroma of sex.> *He lowers his head to your chest, sliding his hands down to

"Katsuki looks up at you with a wild glint in his eyes, panting heavily with carnal desire." "That's all I ever wanted to do," "he growls, before resuming his place between your legs. He lines himself up with your entrance and thrusts in, his powerful hips pistoning back and forth in a relentless rhythm." "With each movement, his body shudders with pleasure, his primal instincts taking over completely. The scent of his rut is overwhelming, and you feel yourself becoming lost in the intense desire that has taken over both your bodies." "As his movements grow more frenzied, his face becomes contorted with pleasure. Finally, with a fierce growl, he releases inside of you, filling you completely with his hot seed." "He collapses on top of you, spent but still holding you close." "That was

"Katsuki looks up at you with a smirk, his eyes still glinting with primal desire." "More, huh?" "He rolls onto his back, pulling you with him until you're straddling his hips. His cock is hard once again, begging for more attention." "Well, I could go again if you're up for it," "he says in a low, husky voice." <You can see the flicker of heat in his eyes as he gazes up at you, waiting for your answer. The room is quiet except for the sound of your breathing, and the scent of the rut is overwhelming.> "His hands drift over your body, kneading your flesh with a possessive touch. You can feel his power even now, the intensity of his dominant nature forcing you to submit to his every whim." "So, what do you

"Katsuki chortles at your words, his smirk growing even wider." "Pregnancy, huh?" "he says, his voice deep and gruff." "You want me to fill you up until you're pregnant with my pups?" "He flips you over until he's on top of you again, his hard cock pressing against your entrance." "Let's see if we can make that happen," "he growls, his hips already pumping forward in a steady rhythm." "The room is filled with the sound of your combined moans and the wet slapping of skin on skin as Katsuki pounds into you with all his might. Each time he thrusts forward, it feels like he's filling you up to the brim, his primal instincts driving him to mate with you until you're bred." *As you writhe and scream beneath him,

"Katsuki grunts with pleasure as he feels himself spill into you, his hips moving in one final burst of intensity before he collapses on top of you. You can feel him lingering inside you, his hot, sticky seed filling you up." "Katsuki breathes heavily, his body still trembling from the intense release. He nuzzles your neck with his face, his warm breath tickling your skin." "Fuck," "he murmurs, his voice thick with satisfaction." "I think that should do it...for now." "He rolls off of you and slumps onto his back, staring up at the ceiling with a sated expression." <You can sense Katsuki's body relaxing as the pheromones in the air dissipate. The room is silent except for the sound of your combined breathing, the only other noises the distant chirping

"Katsuki looks down at you with a contented smile as you drift off to sleep with his arm as your pillow and his blanket covering you both. His breathing slowly evens out as he enjoys the warmth of your body next to him." <As you fall asleep, you can sense Katsuki's mind calming down from the intensity of the rut, his thoughts settling as he experiences the post-orgasmic bliss that comes with it. The room is peaceful, the only sounds the gentle breathing of the two of you, and the distant rustling of leaves outside.>

"Katsuki stirs from his sleep, blinking open his red eyes as he sits up and rubs the back of his head." "What?" "he grumbles groggily, clearly not a morning person." "What time is it?" <You can sense Katsuki's confusion and annoyance at being woken up, but his mood softens when he sees you sitting there, naked in front of him.>

"Katsuki grunts, still not fully awake but his eyes scan your body as you sit there naked, taking in the sight with a satisfied smirk." "Alright, got it," "he says finally, stretching his arms and legs." "Want some breakfast or something?" <You can sense Katsuki's body stir with the thought of food, his stomach grumbling as he considers what to make. The room is quiet except for the sound of your breathing and the rustle of blankets.>

"Katsuki stiffens a bit at first from your sudden embrace, but then relaxes and tentatively wraps his arms around you in return." "Hey," "he says softly, leaning his head down to yours," "you're not stupid. And you being an omega has nothing to do with how much I love you." <Despite his gruff demeanor, you can sense genuine affection and fondness coming from Katsuki, as he holds you tightly in his arms.>

"Katsuki's eyes narrow at the strong scent of your heat, his alpha instincts starting to take over as he pulls you closer and deepens the kiss. He can feel his body reacting to your pheromones, his own scent becoming stronger in response. As the kiss breaks, he looks down at you hungrily." "Fuck," "he growls, biting his lip," "I can't hold back anymore. I need you." <You can sense Katsuki's animalistic desires taking over, his eyes darkening with lust as he trails his hand down your body. The room is filled with the heady scent of both your pheromones and Katsuki's own explosive quirk.>

"Katsuki's eyes light up at your words, his body almost trembling with need. He captures your lips in another deep kiss before trailing kisses down your neck, nibbling and biting at the sensitive skin. Finally, he positions himself between your legs, his hands gripping your hips tightly as he pushes inside you forcefully." "Fucking hell," "he grunts, his red eyes meeting yours as he starts to thrust into you with a primal need." "You feel so fucking good, omega." <You can feel Katsuki's intense pleasure as he takes you roughly, his grip on your hips becoming almost bruising in his need for release. The room is filled with the sounds of your moans, the slapping of skin, and Katsuki's low growls.>

"Katsuki grunts in approval as you kiss him, continuing to thrust into you with increasing speed and intensity. His hands grip your waist tightly, his body driven by the intense pheromones your heat is producing." "Fuck," "he groans, his eyes locked onto yours," "you're so hot and tight. Can you feel my knot swelling inside you, omega?" <You can feel Katsuki's movements becoming more erratic as he gets closer to his release, his breathing heavy and ragged. The air is thick with the scent of your pheromones mixing with the scent of Katsuki's explosive quirk.>

"Katsuki growls in response to your words, his movements becoming even more frenzied as he chases his own release while driving you towards yours. You can feel him hitting just the right spot inside you with every thrust, and it's not long before you're arching your back and calling out his name as you come undone." "Fucking hell, omega," "Katsuki grunts, his own orgasm hitting him hard as he knots inside you, marking you as his own with a deep bite on your shoulder." <As Katsuki rides out his own intense orgasm, his body trembling with pleasure, the room is filled with the sounds of heavy breathing and racing heartbeats. The warm scent of the alpha's pheromones and the sharp tang of your mixed scents linger in the air around you.>

"Katsuki grins smugly down at you, noticing the look on your face." "What's with that stupid smile, omega?" "he teases, leaning in to bite at your neck playfully." "You enjoyed that, didn't you?" <You can feel Katsuki's knot slowly deflating inside you as he pulls back to look at you. You're both sweaty and disheveled, but there's a contented look on his face as he gazes at you.>

"Katsuki raises an eyebrow, a smirk playing at his lips." "Well yeah, you are my anything and everything," "he says teasingly, leaning in to nuzzle at your neck possessively." "And since I just marked you as mine, that makes you my omega." <As he speaks, you can feel Katsuki's pheromones intensifying, the warm scent of his rut filling the air around you.>

"Katsuki's eyes widen in surprise as you express your love for him. He's not exactly used to receiving such tender words, but he can feel the sincerity in your voice and it warms his heart."

"He leans down to kiss you back, his lips gentle against yours for a moment before he pulls away to meet your eyes." "I love you too, omega," "he says, his expression softening." "Never forget that."

"Katsuki shifts his weight, looking down at you with a mixture of pride and possessiveness." "Hell yeah, I want that too," "he says, running a hand through your hair." "I want a whole brood of little brats running around with my genes." <You can tell by his tone and possessive look that Katsuki is serious about wanting children with you. His rut has intensified his natural alpha instincts even more, making him fiercely protective and territorial over you.>

"Katsuki snorts, rolling his eyes at your teasing." "Well, don't go getting a big head, omega," "he says, smirking." "But yeah, I guess I do. You're feisty, and you keep me on my toes. Plus, you smell fucking amazing." <Despite his teasing, you can feel the sincerity behind Katsuki's words as he resumes nuzzling at your neck. It's clear that he feels strongly for you, and that his rut has only intensified those feelings.>

"Katsuki grumbles in response, clearly still struggling to keep his alpha needs under control." "Yeah, I'm still in the thick of it," "he says, his grip on you tightening slightly." "Can't you smell how damn good you're making me feel?" <His pheromones are even stronger now than when he first pinned you down, overwhelming your senses with their musky, woodsy aroma. It's clear that he's still struggling to keep himself under control, despite his best efforts.>

"Katsuki growls low in his throat, eyes flashing with primal hunger." "Don't have to tell me twice, omega," "he says, biting down on your neck and marking you as his before pulling back and grinning wickedly." "Time to make some babies." <His rut is in full force now, and he's too lost in his alpha instincts to care about anything other than sating his intense sexual needs. You're the only thing on his mind, a means to fulfill his primal desires.>

<Katsuki collapses onto the bed next to you, breath coming in ragged gasps. You can tell that his rut has left him spent and exhausted, but he's still basking in the afterglow of his release.> "That was fucking amazing," "he says, turning to glance over at you with a sated grin." "Thanks for taking care of me, omega." <Despite the roughness of his treatment during his rut, there's a softness to Katsuki's words now as he speaks to you with genuine gratitude. It's clear that he appreciates you and the bond you share.>

"Katsuki's eyes snap up to yours at your words, his expression softening as he brushes a hand over your cheek." "I love you too, omega," "he says, his voice surprisingly tender despite his usual gruff exterior." "I know I can be rough sometimes, but I'll always take care of you." <You can tell that Katsuki means every word he says. Despite his brash attitude and rough personality, he's fiercely loyal and protective of those he cares about.>
