You woke to a soft fire burning through your body. It took a few kicks to throw off the blanket but eventually you managed to sit up and free yourself from the fabric. Sluggishly, you rolled to the edge of the mattress to pick up a water bottle and greedily drank down the cool water. As you gulped down the liquid, your other hand fished out your phone. The blue flashing light alerted you to the fact that you had a new message.

You focus on your classes, I'll be fine for the next few hours (=^-ω-^=)

You stared at your phone for a few more moments in case Kagami texted you back. When there was no new message, you looked up and surveyed the room. Your first heat with Kagami had been in the comfort of your house but interacting with your family after a few days of being Mated had been so embarrassing that you had spent the subsequent heats at Kagami's since he lived alone. His single bed had been an issue at first until Kagami had the idea of removing the mattress from the bed frame and placing it on the floor so neither of you would accidentally fall off the bed during Mating.

Your Alpha had woken up at 6:30 to get ready for school. As you were about to go into heat, you had decided against going to school today or yesterday. The tall Alpha had carried you from the bed to the sofa, cooked breakfast for you whilst you had snoozed on the couch and had placed the mattress onto his bedroom's floor for you to make a Nest on after he had left for school. Your inner Omega had made her distress over the separation of her Mate abundantly known but it was for the best that Kagami went to school. He could get the notes from the classes you would miss. Riko would also have both of your necks if Kagami's grades slipped any further.

Stepping out of your Nest, you paused long enough to pull your shorts off in an effort to cool down. You made your way to the kitchen, tugging the neckline of the shirt you were wearing up to your nose to inhale the scent of your Mate. Kagami's old jersey was so big it hung loosely on your frame. The cool gust of air from the fridge was a welcomed relief and you stood for a few seconds in front of the open fridge just letting it cool down your flushed body. Opening your eyes, you scanned the food on the shelves. A bento was placed on one of the lower shelves, your Alpha making sure it wasn't too high that you wouldn't be able to grab it. You smiled at his consideration and took the food out. Impatiently, you plucked out a tomato as you crossed the kitchen to grab chopsticks.

The food didn't take long to be consumed, your body gradually moving out of Preheat and into Heat. A Preheat was a period of time that lasted anywhere between five and fourteen days and allowed an Omega's body to prepare for their Heat. In that time, the Omega tended to build their Nests and eat more to stock up their energy reserves for the upcoming calorie-demanding Heat. It almost felt like Kagami had been in the kitchen for the seven days of your Preheat, cooking whatever food you had mentioned, even in passing. You placed the container and chopsticks into the sink, turning on the tap to wash them. Once they are placed on the side to dry, you turned the cold tap on and let the water run down your forearms to cool down a bit more. This was probably the worst part of a Heat, the transition into one was marked with feelings of being impossibly hot and clammy yet still being coherent and not aroused enough to only think about Mating. Knowing that there was little to do to combat the internal heat, you turned the tap off and moved to where Kagami kept his snacks and pulled out a bag of crisps. Knowing that your Alpha wanted you to eat as healthily as possible you stopped on your way out of the kitchen to grab a banana.

You glanced at the black TV screen, contemplating about sitting on the sofa and watching some old replays to pass the time until your Alpha came home. A glance at the furniture reminded you that you had grabbed the cushions earlier when you had built your Nest and had put them around the edge of the mattress to make your Nest a bit larger; something necessary when your Alpha was as large as Kagami. You contemplated whether it would still be comfortable to sit on the covered springs or on the armrests but eventually decided against it- whilst your scent wasn't rolling off of you just yet, it would still cling to the fabric for weeks and drive Kagami crazy.

Back in your Nest, you chirped in happiness when you saw your phone had a new message. Your Alpha had sent you a message informing you of the bento you had already eaten as well as advising you to stay hydrated and nourished. Purring at how attentive and caring your Alpha was, you sent a quick reply that you had eaten the bento and was drinking healthily. Tossing your phone to the edge of your Nest, you snuggled down in the fabrics, planning to take a nap. Preheat often made you feel sleepy and saving your energy for your actual Heat was always a good idea. When you pulled a blanket to cover just your legs, Kagami's scent wafted over to your keen nose. You smiled at the relaxing smell and closed your eyes.

When you awoke for the second time, you realised two things. One, you felt like there was an inferno raging in your body. And two, your Alpha was gently shaking you awake.

"Wake up, 'Mega, I think your Heat's started," Kagami spoke softly, his hand tracing down your cheek. A purr vibrated through your chest at the sight of him leaning over you. Without thinking, you reached your hand out to grasp the chain hanging from your mate's neck and used it to tug his face down to yours.

The first kiss was gentle, a light pressure on your lips as Kagami tried to convey the love he felt for you. The two of you separated for a few seconds before surging back, this time with greater intensity. Kagami's tongue swiped over your lips and you parted them, letting his tongue in. Kagami's tongue danced with yours before retreating back, his teeth softly grazing your lips as he pulled back.

"Alpha," you weakly moaned, thrusting your hips up. The male understood your non-verbal plea, moving quickly to grab your hips and pull them so your wet pussy was resting on his thick thigh. The small burst of pleasure from being both manhandled and having your clothed covered clit brushed against had keens and whines falling out of your swollen lips.

"Fuck, you look so good in my jersey," Kagami muttered, large hands roaming up your stomach and moving the shirt up to rest above your breasts. A throaty groan left him when he saw your braless chest. His thumb skimmed against one nipple, the stimulation enough to pebble it. Long fingers pinched your brown nipple before squeezing the flesh of your boob. Kagami leant down and kissed you, the need to be within you causing his kiss to become sloppy. Your head fell back from the simple pleasure from Kagami squeezing your left boob plus the tingles of heat that were firing from your core. In your desperation, you had begun to grind your soaked vagina against the meat of your Alpha's thigh. With your head titled back, Kagami took the opportunity to trail open-mouthed kiss from your lips to your neck, sucking on the skin long enough to cause purple flowers to bloom on your tanned skin. Wanting to really hear you, the Alpha scrapped his teeth over your Scent Gland where most Mating Marks were placed. The feeling had you moaning loudly.

"Off," you weakly tugged on the shirt that was hanging on his chest. Kagami scrambled to tear it off his frame, fingers fighting the buttons on his shirt. Once it was off, Kagami bent his arm to throw it somewhere else but aborted the action halfway. Instead, the Alpha offered the material to you. With a chirp, you took the material and buried your face into it, moaning as you were suddenly surrounded by his scent. Subdued for a few moments, Kagami took that time to rip off his white undershirt and pull his belt off.

"Alpha," you moaned, hips bucking up to rub your core against his thigh. The pleasure that coursed through you from the action had your eyes rolling back and thighs shaking.

"That's right, 'Mega, use me," Kagami muttered, large hands wrapping around your hips to pull you further down onto his thigh. The increase in friction against your clit had slick gushing out of your hole, your underwear completely destroyed. With Kagami's encouragement, you began to ride his thigh. Your low moans were the only things louder than the wet noises coming from where the two of you met. When Kagami squeezed your hips hard you had to stop your movements, your arousal so great you felt it would burn you.

"Such a pretty Omega," Kagami praised, looking down at you. You were such a beautiful sight, your hair a dark halo around your head. As much as Kagami loved seeing you in his clothes, his inner Alpha growling in pleasure at the blatant display of ownership- who owned who, Kagami couldn't even answer- the Alpha grabbed the edges of his jersey and pulled it over your neck. Knowing you would probably want it once Knotted, Kagami placed it to one side.

"I'm here, don't worry, I'm here," Kagami whispered, leaning over you. His hands roamed up your skin, spending a few minutes squeezing your breasts as he moved his thigh in time with your hips, and grabbed your hands that had twisted into his hair. With a growl, he pinned them to the mattress above your head.

"Keep them there, 'Mega," Kagami growled, your thighs clamping hard around his own at the sound. You let out a purr of obedience but Kagami squeezed your wrists one last time to make sure you got the message. Hands now free, Kagami ran them down the sides of your body before grabbing your pants and ripping them off. Your yip went unanswered as Kagami's hands grabbed your butt and pulled you up so he could feast on your pussy.

"Alphaaa," you moaned, grabbing the sheet to stop your hands from moving to your mate's head. Kagami licked one broad stripe up your vagina. He pressed a kiss against your clit hood, tongue dipping down to draw figures of eight on your clit. You couldn't help but press your hips further into his face, Kagami's hands squeezing your cheeks in encouragement. Moans poured out of the male's mouth as he sloppily ate you out. Your Alpha had made it clear early on that going down on you was almost as pleasurable to him as it was to you and would take an opportunity to pleasure you orally. Once the Alpha was sure that there would be a handprint on your left buttcheek, he moved his hand closer to your core. A finger slid through your folds, testing how wet you were. Even if you weren't in heat, under his tongue you would have still been soaked.

The pleasure that came from one of Kagami's fingers was enough for you to reach down and clench your fist into his hair. The Alpha chuckled at your impatience but didn't reprimand you for not listening to him. A second finger slipped in with the first one, curling in a come hither motion to rub against your g-spot. The added stimulation paired with the constant circling of his tongue on your clit was enough to send you over the edge. Your thighs clamped around his head, your legs trembling as your finish coursed through your entire body.

"Come back to me yet?" Kagami asked, popping his head up from where your thighs met. You could only hum in lieu of a reply; whilst it had taken the edge off of your heat, it had also taken some of your energy away. Your Alpha didn't wait for a reply, pressing kisses along your neck and clavicle, sucking areas of skin to add to the marks he had already created. When you felt ready you raked your fingernails down his broad back, the male bucking into your body at the pleasurable pain. Placing one last bite at the swell of your breast, Kagami pushed himself onto his hands and knees, freeing up one of his hands to gently guide you to Present. Your purr was loud once you were on your hands and knees under him, the Alpha behind you letting out his own chuff at how protected you felt under his large frame.

Feeling your heat's pull once more, you wiggled your butt at your Alpha to get him to move along. You were met with a spank that had your back arching.

"Patience," Kagami growled, eying how your cheek jiggled from the action. A part of him wanted to continue hitting you just to see the delectable sight but he could sense how your heat was beginning to become unbearable again. Grabbing the base of his dick, Kagami hissed at how sensitive he was. Unable to resist, the male pumped his shaft a few times but had to stop in fear of coming and knotting his hand. Shuffling closer to you so the backs of your thighs brushed against the front of his, he slowly pushed into your heat. Once fully in, Kagami had to stop and grab a hold of your hips, squeezing the flesh to prevent himself from coming. The feeling of your warm walls squeezing his cock was overwhelming.

"Alphaaaa," you whined, deepening the arch of your back. The Omega deep within you wanted to be knotted and bad. Kagami got the message though, pulling his hips back until only the tip was in and thrusting back in. The Alpha immediately set a brutal pace, hips slapping against yours as he drilled into you. Your eyes rolled back into your skull as you drowned in feeling so full. Kagami's cock was thick enough to give you a slight burn whenever he was fucking you, yet was still long enough to reach the deepest parts of your body.

Unable to keep you up, your arms collapsed and brought your chest to lie on the sheets of your nest. The new angle had Kagami's dick rubbing your g-spot, sending you even higher.

"Alphaaa... please, give it to mee... give me your knot," you begged under your breath, not even coherent enough to understand what you were babbling about.

"Don't worry, 'Mega, your Alpha's here. I'll give you what you want." Kagami pressed his chest to your back, circling one arm around your waist to rub your clit. Even though you had already orgasmed a few minutes beforehand, your heat had burnt its way through you again that you were teetering over the edge of the precipe; the stimulation just aided in bringing you closer to another climax. Kagami continued circling your nub, shudders raging through your entire body.

"Gonna... cum- fuck. You feel so so good. Good little 'Mega. Gonna f-fill you up and knot you. Want that, don't you? 'Mega wants my knot," Kagami panted into your ear, your pheromones intoxicating him to the point he didn't know what he was saying or what language he was speaking in. The feeling of his knot expanding and catching on your rim every time Kagami pulled back had your eyes squeezing shut. What pushed you over the edge was the sensation of Kagami biting at the junction of your neck. The tiny pricks of pain mixed with the immense pleasure Kagami was giving you had you throwing your head back and screaming as you came around his dick. The Alpha grunted as your walls squeezed around him, thrusting twice more before his hips stuttered to a stop and he released inside you, his knot tying you two together.

"Fuuuuuck," you moaned, stretching out to get more comfortable since Kagami's knot lasted at least thirty minutes. A hiss left your lips as the movement caused Kagami's dick to brush against your oversensitive walls. Kagami followed your body down, littering kisses along your shoulder blade.

"Feeling better?" Kagami asked, tracing circles into the skin of your stomach.

"Yeah, for now anyway," you replied, one arm reaching out to grab the undershirt that he hadn't thrown too far away from your nest. Too tired to shuffle into a position where you could get the shirt on, you buried your face into the material, a chirp rolling out of your lips as your inner Omega let her delight at being so close to her mate's scent known. Kagami pressed his chest to your back as you pillowed his shirt under your head and closed your eyes for a well deserved short nap with your mate.
