Chapter Text
You had been in a relationship with Shinsou for a few years up to this point. You two had imprinted on each other at a young age, he was one of your only alpha friends from your childhood. Most alpha’s wouldn’t want to associate with someone ‘weaker’ than them well most alpha’s besides your boyfriend. Your omega was almost magnetized to his alpha. Sure he was quiet, calm, and generally not the prime example of a typical alpha, but you knew the true nature of your partner. Behind the seemingly quiet exterior, was someone who thrived off of being in charge, being the strongest . This meant he hated being in rut, the complete lack of composure, succumbing to instincts, becoming a feral shell of his normal self.
Despite being together for years, he never asked you for help during rut and he wouldn’t help you during your heats. It did make you feel a bit dejected at first, like you weren’t desirable or wanted by your alpha. After talking it through with him you understood his uncertainty about fully submitting to his instincts. He’d give you some of his clothes absolutely drenched in his scent right before you would go into heat to help you out a little bit. You would try to do the same but each time you were given the same response, ‘if you gave me anything with your scent it would drive me too far, kitten’.
It was shocking when he actually asked you to help him, despite the extremely evident nervousness when he did bring it up. He had been trying to ignore and disregard bringing it up to you as much as he could. You immediately accepted, not only because denying ‘your’ alpha would be seen as extremely disrespectful and completely out of place for an omega, but you wanted to help after years of dancing around the topic every time.
Of course both being juniors in college made it a bit challenging, you planned to stay in his dorm the days preceding and following, luckily the alpha dorms were mostly single rooms with attached kitchens, one more aspect of the ‘special’ treatment different dynamics receive. The days leading up to the time you were going to stay with him was full of tension. It was evident that he was very nervous, but there were some nerves on your end. No, this wouldn’t be your first time having sex together, but sharing a rut or heat with another person was very very new to not only you but Shinsou as well. Sure you’d started to talk about it a bit more with him, but everything he told you was pretty basic information that you’d already learned. Despite the whole atmosphere around the situation, you really did look forward to going through this with him.

Sitting in your dorm room, you tried to prevent your nerves from affecting you too much. You had a bag packed with basic essentials, clothes, phone charger, birth control, your favorite blanket, and any other little things you might need throughout the week. He’d already told you that he’d have snacks and water as well as a few other things for you to make you more comfortable while you’re with him. You sent him a quick text letting him know you’d be on your way over. Without waiting to get a reply you’d already got your stuff and left your building. The walk wasn’t too long but long enough for you to get stuck in your head.
You had never actually been around an alpha during a rut or during your heat. Of course you trusted your partner, but how out of it would he be? Would he try to mate you? Even though you’d spoken to him about it before and he promised he wouldn’t, you couldn’t help but feel nervous. You did bring a collar to cover your mating spot just in case he was fully out of control. It made you feel a little guilty that you didn’t have complete trust in your boyfriend, but your omega tried to convince you to fully trust your alpha. You’d known him for long enough to know that he would never try anything with you, but you still found yourself fiddling with the straps of your bag while you walked.
The feeling of your phone buzzing in your pocket snapped you into focus. You fumbled as you pulled your phone out of your pocket. Three notifications filled your screen, all from Shinsou.
- Ok, kitty
- The door’s unlocked
- Word of warning, as soon as you walk through that door my alpha will not let you out of my sight. It might be a bit overwhelming but my rut is not in full swing but my instincts are gonna start the take over. I won’t be able to keep my hands off you, sorry about that, little omega
Your face began to heat up at the nicknames he called you, no matter how many times he did it always got you flustered. What did he mean he wouldn’t keep his hands off you? A ball of anxiety settled back in your stomach again. Without responding you continued your trek to the alpha dorms.
As you approached the big glass doors, you remembered one crucial detail about getting to your boyfriend. A lone omega walking through the alpha dorms was not only scary to you, but also very risky. Technically you were an ‘unmated’ omega, you and Shinsou had imprinted on eachother but you had never received a mark from your partner. Your hand ghosted over the spot on your neck subconsciously, the other gripped even tighter on the strap of your bag. The only thing you wanted right now was the comforting scent of your partner to stop you from spiraling into your own anxieties. With your hands shaking slightly, your hands return to your phone quickly dialing your alphas number. It rang once before a concerned voice greeted you.
“Are you ok, Kitty? What's wrong? Are you hurt?” His normally calm voice came out rushed and frantic, his voice sounded almost strained and raspy
“I’m okay, I’m okay, it’s kinda dumb but could you maybe stay on the phone with me?” you asked cautiously, the situation made you feel a little embarrassed.
“Of course, omega” He responded sounding a bit calmer and put together, “I’ll stay on as long as you need me baby.”
“Thank you, Toshi” using your nickname for him always made him a bit more calm and happy, you hoped that helped. He was probably fighting against the instinct to run and get you back to his room but you both knew the risk of an alpha about to hit his rut being around any other alphas, it was a recipe for disaster. Thinking back on him being an alpha, you remembered his message from earlier, “oh Shinsou? Not to be awkward but what did you mean before about not being able to keep your hands off me?”
“Well, kitty” he chuckled into the phone, voice a little deeper than usual, “my alpha brain is screaming at me to protect you, to take care of you, keep you with me, show you that you’re mine. I know it sounds a little weird especially since my rut’s not full blown yet but this is normal for me but I thought I’d give you a fair warning, omega”
“Oh uh, got it” You felt your face begin to heat up at his words, no doubt a blush covered your cheeks. Half noticing his redundant use of the name ‘omega’ which made sense with his current state, also the roughness of his voice that came through the phone. You walked through the building, and up a flight of stairs. So far you hadn’t run into any other alphas, thank god. Pushing open the door from the stairwell to the hallway, you were quickly approaching your destination. “I’m almost at your dorm, on the second floor right?”
“You got it baby,” his sentence was interrupted by a low growl, catching you by surprise. “Fuck I can practically smell you from here, missed you so much Omega”
“Really?” you suddenly felt very small, very out of place, could every other alphas smell you? That could be a problem even if you were a few feet away from his door. As you were about to sink deeper into your thoughts, the familiar smell of your partner began to fill your senses even though it was extremely faint. Before you could even reach the door handle, the door swung open revealing your alpha. The sudden intensity of his scent hit you like a truck.
He was only wearing a pair of loose grey sweatpants, no shirt, a faint sheen of sweat covered his form, pupils dilated when your eyes met his own. You were quickly yanked into his arms, lips instantly finding yours. His hands ran down your back, one resting on your ass, the other on your lower back. The air around you was absolutely drenched in his scent, intoxicating and comforting. As his lips moved against yours, a low growl came from his throat coaxing out a whine from your omega. He pulled away slowly, hands still resting against you, a smile splayed across his face.
“Missed you so much, kitty. Sorry about being so aggressive, are you sure you still wanna do this? You could easily walk out now, i'm not trying to force you to help me out.” The lingering doubt filled his words, but you knew what you were getting yourself into.
“Shinsou listen to me” you looped your arms around his neck, looking him straight in the eye, “If I didn’t want to be here, I wouldn’t have come at all. I’m going to stay here with you until the end ok?”
“If you say so, omega” He kissed your forehead, taking a deep breath and nuzzling into your hair, “Room? please.”
You smiled and nodded, the little please at the end was enough to melt your heart. Before you could verbally respond, he hoisted you up into his arms, wrapping your legs around his waist, you buried your face into his neck as he began to walk towards his room. If you thought the scent was a lot when you entered the dorm, his room was almost suffocating. It was clear that this was where you’d be spending the majority of your time, a large pile of blankets was thrown onto his bed as well as a few pillows and clothes, his room somewhat of a mess, curtains drawn, his tv playing some show you hadn’t watched before. He placed you down on the bed, arms framing your shoulders propping himself up above you.
“Pretty omega,” he mumbled before planting a kiss on your neck, nuzzling into your scent gland taking a deep breath. The action made you tense up, normally he would ask before doing something as intimate as this. The way he reacted indicated that he noticed your discomfort, immediately pulling away eyes wide, his scent turning sour causing your nose to scrunch. “Holy shit, I’m so sorry Kitty that was a little too far. My instincts are fucking me up, I’m sorry I promise.”
“Alpha” He snapped out of his rambling, that name seemed to bring him to attention in a second. You reached your hand up to his cheek, rubbing your thumb across his temple. Trying your best to produce calming pheromones despite the sour smell around you. He leaned into your touch, eyes closing slightly. “It’s ok, I know you didn’t mean it. I was just a little surprised is all, you did nothing wrong.”
“M’sorry still” he muttered, sounding calmer now which was a good sign. His scent returned to normal as he took a few deep breaths of yours. He stood up in front of you, allowing you enough space to sit up straight instead of laying down. Sitting in front of him only accentuated the height difference between the two of you. “Do you want me to go get your bag?” after he asked his question he hung his head a bit, “I will, but I just need you to tell me you aren’t going to go anywhere. I know it’s kinda stupid but my Alpha won’t let me leave the room without you saying that”
“I promise you, my alpha, that I will not leave this room or this bed without you knowing” You said with a smile, playing it up to try and ease Shinsou’s nerves. “And yes could you please go and grab my bag, I’m gonna need it if we’re gonna stay in here the whole time”
“Thank you, kitty” He bent down to give you a quick kiss before exiting, “make yourself comfortable, I want this to be as much as it is for you as it is for me.” With that he was out of your line of sight. You lay back onto the mess of blankets behind you, maybe it was the overwhelming smell of an alpha, or the small amount of nerves you felt, but the need to nest was becoming hard to ignore. After all he did say to make yourself comfortable.
You began to sort through the mass, separating the thicker blankets for the edges, rubbing your wrists and neck on the cloth until you were satisfied with the scent of not only the alpha but you as well. After a fair amount of scenting, adjusting, and placement, you were feeling a lot less nervous, much more comfortable in your partners room.
You were so caught up in building your nest that you hadn’t realized that Shinsou was in the room. He stood patiently waiting for you to be finished, leaning against the door frame not wanting to intrude. When you finally noticed him, immediately you felt your body heat up. You found yourself unable to make eye contact, instead focusing on the fabric of your shirt as you fiddled with the hem. His footsteps made their way to his bed, in your peripheral you could see him crouching down to be eye level with you.
“Baby?” his deep voice broke the silence, causing you to subconsciously look up at him immediately. He looked around you and then back at you, cocking his head to the side. A silent way of asking if he could join you, it was considered very offensive and invasive to invite yourself into an omegas nest no matter what your relation may be. You nodded holding your arms out in his direction. Carefully, he climbed in next to you, hugging you close to him as you both layed down. The show on his tv provided faint background noise. Cautiously you nuzzle yourself up against his neck. As you closed your eyes, his hand reached up to card through your hair.
The familiarity of the two of you holding each other calmed the rest of your nerves. You did have to remind yourself that just because he was about to hit a rut, he was still your boyfriend who you loved and who you trusted. Smiling against the skin of his neck, you felt the familiar haze of comfort and drowsiness fill your head with cotton. Thoughts now hand in hand with your Omega, willing to be there for your alpha but knowing that you’re there for your boyfriend. The sleepy comfort was broken by a slight chuckle from the man next to you. You lifted your head to see Shinsou’s face.
“You were purring, Kitty” he smiled at you, pupils a bit bigger than usual, “it was cute.”
“Alpha’s warm ‘n cozy.” You smiled back returning your head back to its place against his neck.
Comfortable silence followed suit, returning to the drowsy state you’d felt earlier. The noise from the TV was just enough to block out any of the outside world, the warmth from your boyfriend provided you with just enough heat to keep you warm, the feeling of his fingers tracing idle patterns against the exposed skin of your arms. His movements slowly began to turn into more erratic, frantic, touches instead of soft smooth ones. He pulled away to sit up, his knees bent, hands rubbing his face, not facing you. Most importantly, he whined. You had rarely ever heard another alpha, let alone Shinsou whine before. It was clear he wanted to say something but there was something holding him back from saying anything to you.
“Toshi?” your worry evident in your tone. Of course you were worried, all you could think of was that you did something wrong somehow and made him uncomfortable. Without even realizing it, your body had begun to release distressing pheromones. He turned to you, a look of embarrassment plastered on his face. He finally spoke up.
“God this is gonna sound so fucking creepy, but could you maybe put shorts on or one of my shirts? My brain is fucking screaming at me to see you and, well, touch you. I wanna get this settled now before I can't control it anymore.” he rushed out, clearly embarrassed about it. His face had a slight blush across his cheeks, eyebrows knit together, lips in a small pout. He clearly had overthought this interaction, because you saw nothing wrong with changing. Afterall pajamas or just one of his big shirts sounded much more comfortable if you were to stay this close together. You giggled at the way your partner was acting, how it was completely different than normal.
“I don’t mind anything I can do to help you right now I’m totally ok with.” you said, “I have some shorts in my bag if you’ll give me a shirt” moving to get out of your nest over to your bag, you were stopped by a hand grabbing your wrist and a low growl emitting behind you. You turned to see Hitoshi staring at you like you were some sort of prey. Your instinctual reaction to his behavior was to lower your head. Remembering his statements from earlier, he wouldn’t let you out of his sight and he needs to keep you next to him. You could hardly whine out a response due to the sudden anxiety that now flowed through you. “I’m just going to my bag, Alpha. I’m not going to leave, I promise.”
“Thank you” he responded, matching your quiet volume. As you climbed out of his bed, you felt the bed dip and he followed suit, his gaze remained trained on you as you walked across the room. He really wasn’t kidding when he said those things to you, but this was a new experience for you as well being around an alpha in rut.
You bent down to go through your bag, pulling out a pair of black shorts you turned to face him looking for approval. With a nod he brought you up to your feet, slowly starting to communicate more nonverbally as the day continued. He walked you back over to the nest, as you sat back down on the mattress he leaned down to kiss you softly. Seeming to somewhat return to normal, he stood back up and began to walk over to his closet. “You can change while I get you a shirt, I won’t look, pinky promise”
“Like you’ve never seen me naked” you joked as you changed into the shorts, now feeling a little colder than before. Kicking your pants to the side, a big black t-shirt was thrown at you from across the room. Picking up the soft fabric you quickly slipped it over your shoulders. Smiling as it fell to your mid thigh, practically swallowing you completely. It was a reminder of the sheer difference in size between alphas and omegas. You pulled the shirt up to your nose and keened at the smell of your partner. Yes the room was already drenched with his pheromones but something about wearing his shirt made you feel safe.
You were so lost in your own feelings, you didn’t notice him crawl back into bed behind you. You felt his arms wrap around your torso pulling you towards him. His body rested against his headboard, legs splayed out on either side of you, your back against his chest, his chin rested on your head, both partially paying attention to the show playing in front of you.
Snuggling up against him, the exhaustion from your anxiety and stress began to finally take hold. Your eyes began to drift close, focused on the warm hands running up and down your thighs and the rhythmic rise and fall of Shinsou’s chest behind you. Falling into that comfortable state you both had before. His head leaned down next to yours, the feeling of his breath tickled your ear barely keeping you awake.
“Tomorrow,kitty, it’s gonna get bad” he said quietly, “If you aren’t sure or if you don’t want to do this, I understand. I mean yeah it would hurt the hell out of my instincts but I don't want you to feel forced into this.”
“Hitoshi, I know what I’m getting into and I have no reason not to trust you. Sure this is new but I would be hurt much more knowing I couldn’t help you” reaching up behind you and cupping the side of his face to look at him, placing a quick kiss on his lips you let go and lay back against him. “Now stop worrying, and get some sleep.”
“Thank you,” he sighed into your hair, kissing the top of your head whispering out a hardly audible ‘love you’.
