Dazai is the only one capable of giving Atsushi a moment of clarity in his mating brain haze but he hates that babysitting has become his full time job for the week. He stuck the spare key in the door only to find it already unlocked. That wasn't a good sign but Dazai has dealt with worse before so he might as well check the damage and get it over with. To his surprise he found you and Atsushi sound asleep in each other's arms tangled in a mess of limbs. It was cute if not mildly sickening but at least it looks like something finally transpired between you two. You both were super dense to the point everyone in the office was aware of your feelings for each other. He needed a picture of the scene in front of him for future blackmailing purposes, that and Dazai started taking bets on how long and who would confess first.
The click of his phone camera was what stirred you awake, Dazai forgot to put it on silent. You tried to unwrap yourself but Atsushi pulled you back in. Slowly your eyes flutter open to see Dazai waving a phone in your face.
"Good morning sunshine! I’m surprised you're both fully clothed still."
You yawned "Why wouldn't we be?"
You tilted your head as you tried to pry yourself from his grasp. Atsushi placed a kiss on your exposed neck while glaring down Dazai. You bit your lip hard to prevent an embarrassing whimper from vocalizing. Dazai crouched closer as Atsushi moved to bite down where he was kissing but before he could place his fangs on your skin Dazai poked his forehead.
"Aaaaand that’s enough, down boy." The brunette watched as his eyes faded from blue back to the original mixed tone.
As Atsushi regained his clarity he sputtered into action pushing himself as far away from you as possible "(Y-Y/N)? D-Dazai? What are you doing here?!" He sounded confused like he didn’t remember your confession from an hour ago. The only thing he remembered was Yosano sending him home.
"Same as last year, I'm here to make sure you don't wreck the place." Dazai sighed, waving his arm around.
You tilted your head to the side. "Same as last year? Did Atsushi get a fever last year too?"
Dazai and Atsushi blinked at you. Did you really have no idea what was going on? "You mean no one told you!" Atsushi screamed, hiding his face while Dazai keeled over laughing. “You two really are meant for each other!”
You frowned at Dazai’s reaction but his words only made you more confused “I mean all Yosano told me was to confess before April. She didn't explain why.” You shrugged, Dazai was there when it happened so if anything you'd blame him for not saying something sooner. Atsushi perked up at that statement. “Wait, Yosano said what? Hold on-”
Dazai dragged Atsushi out of the corner by the back of his collar on his pajamas. “Well in April our little tiger over here goes into his mating cycle! Yup a whole week of nonstop-”
Atsushi smacked Dazai with his pillow to get the other to shut up. “She doesn't need details! It's bad enough that I forced her into bed.” He sheepishly looked off to the side trying to get Dazai to let go of his shirt.
Dazai's words were enough to jumpstart your imagination. Your usually sweet and caring Atsushi being consumed by his animalistic desires? The way his piercing gaze would be filled with lust. How he'd be so desperate to be inside you that he couldn't help but handle you roughly, pinning you down. The only thing that would be running through his head would be his desire to fuck you senseless. His animalistic desire to breed you, to make you a mother, the mother of his children. Your cheeks were a deep crimson just thinking about it. You cleared your throat to shake away the nerves but it didn’t stop your voice from being shaky.
“I came to the lion's den on my own accord, Atsushi, you didn't force me to do anything.” His eyes locked with yours in surprise. You bit your lip before turning away. “Besides I would have let you have your way with me.” You didn’t mind admitting that to Atsushi, however it did make your skin crawl knowing Dazai heard it too.
The room stayed silent for longer than was comfortable for you. The pause was almost as pregnant as you were about to be. You shook that thought out of your head. That was a bad joke, horrible really. Poor taste. You need to get your mind out of the gutter but you couldn’t help it. Now that you know that’s an option you almost want it more now than ever. Maybe without the child but the idea still stands and you found it hot nonetheless.
Everyone was staring. Dazai smirked and stood up abruptly. “Well then that settles it! I'll check with Yosano to get you a contraceptive but other than that it looks like my job here is done.” The brunette got up from the floor.
Atsushi scrambled to his feet trying to stop Dazai from leaving “Wait that's it you're just going to let me-”
Dazai pulled Atsushi closer, turning them both away from you. “Look, you have a very attractive woman who is willing to sleep with you during your rut, why would I stop you? If anything I'm a little jealous.” Dazai joked in a hushed tone so you couldn't hear. All you saw was the boys huddled by the door.
Atsushi was skeptical about his antics but couldn't fault him for it. He knows his ability's side effects just make more work for everyone. “What if I hurt her, or worse scar her for life?” He's not entirely conscious for most of his rut but he's also never had a partner before, period. Atsushi doesn’t really know how big of a difference it will make.
“Well you are two consenting adults and if anything as your “mate” I think you'll be more protective of her safety. You only wanted to mark (Y/N) because I got too close.” Dazai let him go, giving him a thumbs up as he closed the door behind him.
You watched as Atsushi stood frozen in the doorway. It must have hit him that you were now alone with him. You smirked, oh how wrong he was. Flopping back down on his futon, you stretched so that your shirt was sliding up, exposing your stomach. You've never liked your stomach, you always thought it was too pudgy but this was about showing him some skin. As you let out a lewd mewl you knew you caught his attention. You weren’t stuck in here alone with Atsushi, oh no, Atsushi was stuck in here alone with you.
“(Y/N)!” He covered his eyes with his hands but you could still see that he was peeking through his fingers. “What are you doing?!”
Giggling you rolled over continuing to stretch, making sure to present your ass nicely for him. “Helping obviously.” You let out another mewl biting your lip. The glint in his eyes didn't go unnoticed. The color was swirling into the tigers blue with each passing second. Atsushi took a sharp breath. “This isn't funny! I could seriously hurt you!”
Sitting upright you stopped your teasing. “Atsushi, I trust you with my life.” you hummed thinking of how else to ease his mind. “Come here for a second.” You patted the spot next to you and waited for him to sit down. He sighed but hesitantly crossed his arms as he sat down. You leaned over his lap until your noses were almost touching.
“Do you love me?”
He blushed but didn’t deny it. It took him a moment before you felt him gently grip your shoulders to push you away slightly so he could see all of you. “...I do...” Atsushi trailed off waiting for rejection but it never came. Instead you grabbed his cheek and smiled. “I love you too. Now how about you have a little faith in yourself, yeah.” Atsushi’s eyes widened as the last bit of original color left and turned blue. He leaned forward into your personal space but you let him as you pressed your forehead against his.
“We’ll start off slow okay.” You crawled into his lap nuzzling into his neck. That got him to purr as he slowly wrapped his arms around you taking in your scent. His grip tightened around you. Soft, warm and overall enticing. Atsushi was breathing you in deeply, panting into the crook of your neck. Hesitantly he gave a small peck and you hummed mirroring his action. You sighed pulling away just enough to place a proper kiss on his lips. You felt his full body tense before he melted into the kiss finding a way to hold you closer.
His hands massaged your skin in a similar rhythm to the kiss, heavy and slow. You could feel his bulge growing hard underneath you as you playfully bit his lip. He growled under his breath as he pinned you to the futon. Atsushi’s eyes were sharp like he wanted to devour his prey but then you could see the light behind his eyes flicker and he pulled back.
“S-sorry I didn’t mean to-”
You reached up to pull him back to you, wrapping your legs around his waist. “No, no more apologies, I want this as much as you do.” Crashing your lips together you could feel him loosen up a bit as you nibbled on his lower lip. Pulling his hips into yours you tried your best to grind into him from below. “I need you Atsushi, please.” You begged in between the kissing and heavy petting.
“Fuck,” You felt Atsushi’s hips jerk in just the right angle to send a jolt of pleasure through you both. “You can’t just say things like that.”
You giggled, it was too fun to tease him like this. You watched as his eyes shifted when you started to remove your clothing. “Oh yeah? Then whatcha gonna do about it tiger boy.”
His hands immediately moved to explore the new exposed skin. “God you’re so hot.” He leaned down to pepper kisses all over your body, nipping at the skin near your bra as he lifted you up just enough to mangle the clasp to set your boobs free. You gasp at each suck and kiss he placed on your skin. Each whimper sends his hips to rut desperately against you.
Your fingers made quick work of the buttons on his pajamas as you raked your hands across his body. Atsushi’s breath hitched as you palmed against his member. He groaned as he thrusted into your hand. “S-shit, that feels so good.” His eyes wired shut as he lapped up one of your nipples while he pinched the other with his fingers. You mewled at the sensation and lightly dragged your nails across his back. “Nghh~” You could feel the pleasure pool in your stomach.
“Please Atsushi, I want more.” You moved to pull his hand down to your heat. “T-touch me here.” You stutter through your ecstacy.
You both practically shove your hand down each other's pants with a frantic effervesance of trying to give the other pleasure. Atsushi licks and sucks on your neck all the while moaning as you stroke him. “God you’re so wet for me.”
“Yes, all for you.” You were breathless. “Please, take me already.”
Both of your patience were running thin as you disrobbed the last articles of clothing. The skin to skin contact was making you dizzy. Atsushi was so warm to the touch but then again so were you. Atsushi took a moment to take in all of you. This was all for him, a feast for his eyes. Atsushi melted on top of you using both hands to cup your face, stealing another kiss. The last thing he wants to do is hurt you but he feels so good.
He licked his lips before he crouched down to taste your heat. Your head lulled to the side at the sensation of his hot tongue eating you out. The feeling was short lived as he groaned, lining himself up for the main event. He rolls his hips as controlled as he could, pushing in completely as you gasp.
The noise that came out of both of your mouths startled each of you for different reasons. You because Dazai wasn’t kidding about Atsushi’s ever growing desire and Atsushi because you really want him and he wants you. He wants you so bad he didn’t even notice that he was already thrusting into you. A mess of moans fill the room as you try to mentally keep up with Atsushi’s whirling intensity. You were so full it made you breathless. Each thrust felt like the wind was being knocked out of you. Each time Atsushi sank deeper, pressing against all the nerves that made you spasm with beautiful sensations of pleasure to the point where you couldn’t think straight. At this point any coherent thought you had was reduced to the stars you see painted on the back of your eyelids from them being wired shut in bliss.
Atsushi huffed above you moving your body impossibly closer as his release washed over him. He bit into your shoulder rutting into you until his orgasm subsided. You were dazed, overstimulated and about to say something when your world flipped over and Atsushi began pounding into you from behind. You come near immediately as he buries himself deeper into you. He doesn’t stop let alone notice since he’s chasing his second high. He’s sucking hickeys all over your neck and shoulders and the feeling is divine but overwhelming and has you screaming into his pillow. It wasn’t too long before you felt the warm rush of him filling you to the brim. You tried your best to catch your breath as your eyelids fought off the exhaustion. They lulled shut to the subtle rocking as Atsushi continued to thrust into you as you passed out.
