First time? Older!Hiro x Reader

   "(Y/n) - I know you already. If we go in you're gonna fall in love and -" Hiro pulled at your wrists, begging you to step away from the pet store but you interrupted him. 

   "Oh no Mr. Hamada, don't pin this on me! I can control myself around these adorable creatures. You on the other hand cannot." You giggled and stuck your stern finger in his face. You tried to act as serious as possible, but it failed immensely. Hiro laughed along with you and pretended to bite at your finger.

   "Touchè pretty lady. Fine we'll go in - BUT - I get to buy an extra bag of Gummy Bears later all for myself." Hiro clicked his tongue triumphantly and opened the door to the pet store for you. You rolled your eyes - he bought three bags of gummy bears for himself anyway, no matter how many times you attempt to put them back.

   As soon as you both walked in you both were greeted with a strong smell of puppy breath and cleaning supplies and barking of all kinds. Hiro and you cooed at all the different kinda of dogs - small or large. Skinny or fat. 

   "AWWW who's a cute lil fella! You areeeeee!" Hiro poked at a cage with an American bulldog sitting lazily. It's tail perked up slight at the sight of his new visitor. You watched him with heart eyes as he continued to coddle the puppy. He was just too cute....

   "Hi there! Is there anything I can help you with?" A cute little old lady came venturing over, with a parakeet lounging on her shoulder. Hiro stood up, eyes widening in amazement. 

   "SCAAAAWT- can I help you? SCWAAAAT" the bird repeated after her. You guys giggled together at the interesting bird. 

   "Nope, we're kinda just looking right now. Who's this fella here?" You reached out to the bird to slowly pet his head. 

   "This lady here is Bunny - she's my right hand lady. She says anything she hears and and sees." The old lady chuckled as the parakeet walked farther down her arm to inspect Hiro's mess of black hair. He laughed at the curiosity of the bird.

   "Bunny? Odd name for a bird. How'd she get it?" He giggled at her pecks to his messy black hair.

   "Well having a mop for hair is pretty strange, don't you think?" She winked over at you two, causing You to laugh at your boyfriend. You mouthed over to him 'she got you good!' Which earned you a scowl from Hiro. "Her white feathers reminded me of a bunny so I decided why the hell not." She chuckled. Hiro bumped shoulders with you for no apparent reason, and you reached up to smack him in the head. (Although Hiro was at least a head taller than you, so it was deemed slightly impossible)

   "SCWAAAT- true love SCWAAAAAAT." Bunny squealed loudly. The little old lady smirked at the young couple in front of her. You guys both turned a light shade of red at the birds words.

   "Hey- she calls it like she sees it." The old lady winked once again. "If you need me, I'll be picking up dog shit." She waved off, taking Bunny along with her, screeching 'dog shit' over and over. 

   "Fred would be ALL over her. She's crazy."  Hiro fell back in laughter. He circled his ears, gesturing the 'cuckoo' sign. You  held back your giggles and shushed your boyfriend up. 

   "Hiro! She can hear you oh my god." She held in her giggles. You moved farther into the store, Hiro behind you, holding on to your waist, and you picked up your DSLR camera to get shots of the puppies all around you. 

   "There's so many of them, Wasabi and Honey Lemon would have a field day in here!" Hiro poked at the glass of a cage with a Pomeranian inside. 

   "I'm pretty sure Gogo would too. She would just have to take some time to melt." You replied, with your eye behind the lense. Then you stopped on one particular black puppy. "OH MY GOD!' You drop your camera from your grasp and let it hang lazily around your neck. You began to hit your boyfriend repeatedly on his chest to quickly get his attention. 

   "What what what???" Hiro grabbed a hold of your wrist so you would stop hitting him.

   "DO YOU SEE THIS PUPPY?" You pointed at the fully black Shiba Inu puppy. His tiny face literally smiled back at her; he kinda resembled a black fox. "HE LOOKS LIKE A FOX BABE." You shake his arm violently. "I WANT HIM." You pouted once again because you knew you couldn't get him. 

   "HAHA see I told you! (Y/n) we can't and you know that." Hiro slowly reminded you but with every word your face fell slightly. His heart hurt seeing you so sad. 

   "I know - I'm sorry babe." You grimaced slightly, and fell into his hold. The little black puppy pawed at the glass, begging for your attention again. "Can we just - say hi to him?" You gazed up at Hiro with a little bit of hope in your eyes. Hiro bit his lip, contemplating the decision because he knew you. But of course, he couldn't help but give in.

   "Yeah sure, I don't see why not." Hiro grinned, his eyes softening just seeing how happy a 'yes' made you. And so - the little old lady brought out the little black fox dog that you seemed to have had an instant connection to. 

    You both soon learn that his given name from birth was Foxx, due to the fact that his face resembled a baby fox. He was only 7 months old and he was fully potty trained. 

   "Oh wow he's so perfect!" You giggled as he hopped in your grasp. Hiro stood to the side awkwardly, trying not to get attached to the puppy. But instead fondled with your camera, in hopes of getting some cute pictures for you. But he just couldn't get the damn thing to work...

   "(Y/n) your stupid camera won't-" Hiro pressed numerous buttons but all he got was a black screen. 

   "Hiro you're a robotics genius and you can't figure a camera out?" You giggle, not paying attention to him. "Just don't break it again." You warned him but it came out as a giggle instead. Hiro rolled his eyes because yes, a genius like Hiro doesn't know how to operate a DSLR camera. The old lady reached over and removed the camera lense and patted Hiro's back with a laugh. His cheeks burned bright red; he was ashamed a camera was something the could stump him.

   "Sometimes it's the little things son." She laughed lightly. (Hiro was so embarassed) he got a couple of cute pictures before he gave up and ended up getting some on his phone and sending the group chat a picture with the caption: 

Hiro: So (y/n) is starting to fall for a smaller, much cuter little guy (( 

Tadashi: Always knew she'd leave you, knucklehead!

Hiro: hey!

Y/N: it was inevitable, Tadashi.

Honey Lemon: AWW! That's adorable! Where is this?

Wasabi: AH HE LOOKS LIKE A WOLF

Fred: Duuuude that's totally a wolf?

Fred: right guys?

Gogo: Nice. Make sure she doesn't get too attached Hiro. 

Hiro: No Fred, it's a puppy. And I think I'm a little too late with the whole attached thing. 

Hiro: help.

Tadashi: reasons why you're such a knucklehead.

Gogo: Your issue. Not mine!

   Hiro chuckled before looking back up to you. He watched you with heart eyes, thinking to himself 'wow I really caught a good one here." As you lifted the puppy into the air and you giggled , making Hiro laugh too. 

   "You guys are too cute." He sat next to you on the bench. Hiro laid his head in your shoulder so he was near your height. 

   "So are you." You brought Foxx close to Hiro's face, and he licked him right on the nose. 

   "Picture?" Held up his phone for you to see. You held Foxx close to you while Hiro kissed Your cheek. You steadied his arm as he snapped a quick picture before sending it to the group chat again

Hiro: Yup, we're both whipped guys. Send help. 

Hiro: SOS 

Honey Lemon: Awww! Hiro you guys are so adorable.

Wasabi: do I sense a mini family?

Tadashi: Don't give him any ideas Wasabi.

Y/N: okay guys calm down now. 

Hiro: -____-

Gogo: Just like your pussy whipped?

Tadashi: Hiro do you even know what that is? 

Fred: Dude that went 0-100 so fast 

Y/N: half a mind to leave this conversation 

Hiro: *you're

Hiro: and I might be, but in good reason. You're just jealous because we have a cute puppy.

Hiro: And yes Tadashi I know what that is idiot -___-

Gogo: oh bite me

Hiro: I'd rather not.

 

    "You're so mean to her." You nudged his side, warning him. He gave you an unapologetic look before folding his arms across his now chiseled chest,  

   "Don't try to change this subject on me now (y/n)." This time he gave you a stern look. "Honey cakes - we have to go now. I have a project to finish up and it's going to take me all night." Hiro knew what your reaction would be already. Your lip quivered slightly but you understood. 

   "I wish we could get you Foxx." You  kissed his little button nose. As much as Hiro hated to admit it, he wished you guys could get the puppy too. 

   You hesitantly gave back the puppy to Sherri (you finally learned the ladies name) and you and Hiro slowly left the pet store with a somber feeling. 

   "Baby, please don't be sad." Hiro rubbed your hand comfortingly. He kissed your nose right where the puppy did to make you feel better. 

   "I'm not, don't worry." You sighed, leaning your head on to his chest as you walked back to the lucky cat cafe. 

   "One day, we'll be able to adopt our own little puppy and start our own little family." Hiro surprised you with this one little statement. Your heart leaped into the air with excited nerves. 

    "You promise?" You stuck out your pinky to Hiro. His large brown eyes softened, and he grabbed you to pull you closer to him.

    "Cross my heart." He smiled at you and pressed a soft kiss to your lips to seal the deal. 

    "I love you, you ding dong." You murmured before kissing him again.

    "I love you more, you idiot." He whispered back, kissing your cheeks, lips, forehead, and neck. 

   "Oh yeah; don't call me honey cakes ever again." You smack him on his head, but the fluff on top blocked any sort of pain to reach his head. 

   "Noted, never again." His reflexes got the best of you and he held your hand tightly. (Not like you were complaining) 

    That night you and Hiro lounged around in his garage, as he worked on his latest project. You and Baymax played a friendly competition of chess, before Tadashi came and checked on the both of you. 

   "Hey guys, it's getting pretty late. I'm turning in. (Y/n) are you staying over tonight?" Tadashi ran his fingers through his now unruly hair. 

   "Yeah, I have to help Hiro transfer his project to the lab in the morning." You look up momentarily to smile at Tadashi. 

   "Alright I'll take the couch, you can sleep in my bed. Night you two! Hiro, you better get some sleep in." Tadashi glared at his younger brother. You chuckled at the fact that Tadashi still bothers to sleep on the couch when you end up in Hiro's bed anyway. 

   "Yeah yeah." Hiro paid hardly any attention to him.

   "(Y/n), Baymax, can you please make sure he gets some type of rest please?" Tadashi looked at you, an irritated look in his eye. 

   "Of course Tadashi." Baymax replied for you. When he was content with the answer, he let the door slowly shut behind him. You took a quick glance at the clock to your right , which showed 12:31 am exactly. 

  "Hiro I'm giving you an hour to finish up before we are headed to bed." You stand up and walk over to him. You wrap your arms around his shoulders and lay yourself on top of you.

   "I can't concentrate if you're on top of me like this." Hiro stops writing to turn his head to you.

   "Hiro's neotransmitter levels have increased drastically when you touched him (y/n)." Baymax turned his head to you guys. You giggle at Baymax's ways of being so blunt. Hiro groaned, his cheeks turning pink.

   "Thank you, Baymax. I am satisfied with my care." Hiro rubbed his eyes, attempting to get the tired out. Baymax stood up from where you and him were playing chess, and went upstairs to return to his port. "I swear Baymax is going to be the reason why I will never get laid." Hiro turned around so you could sit in his lap. 

    "Oh shut up, who would you get laid by?" You smack his leg playfully. You relax in his arms, and realise that you are so exhausted. 

   "I think I'm ready to turn in now. This is really nice." Hiro snuggled his head into the crook of your shoulder. 

   "I know, me too. It's been a long day." You yawn and your eyes close slowly. Suddenly Hiro's strong arms encompass you and you feel your whole body being lifted. Your eyes fly open and you realise Hiro is carrying you. "Hiro! I have legs!" You protest, kicking slightly.

   "Keep it down you'll wake up the lil devil mochi." Hiro warned you, and quietly brought you up the stairs. Tadashi was already knocked out on the couch, with Mochi cuddled into the dip of his back. He brought you up into his and Tadashi's room and kicks the door lightly, leaving it slightly ajar. (Aunt Cass is still a smidge uncomfortable with you guys sleeping together alone in a room) he gently places your bum on his bed before turning around and removing his pants. You turn over, blushing at the sight of your half naked boyfriend.  

   "Here, you can change behind the screen." Hiro tosses you a t-shirt that's 2 sizes too big to you. But you felt a little adventurous tonight. You sat up in the bed, and began removing all the articles of clothing you had on. Hiro turns around after slipping on his pajama's and is shocked to see your now bare naked back, no pants on. He gulped and slowly slipped into the bed beside you. You smirk to yourself, knowing that Hiro was most definitely affected. You slip on Hiro's t-shirt and turn to sit cross-legged on the bed. 

   "Hiro you're staring is making me nervous." You say as you start folding your clothes neatly before you. He rolls his eyes, even though you can't see it. You take your neatly folded pile of clothing and purposely reach over Hiro's body, your chest just barely rubbing off on to his, to drop it in the drawer. "Sorry." You bite your lip, knowing full well what you were doing to him. Hiro's eyes darkened; you squeak when his arms snake around your waist and he's now on top of you.

   "Teasing is a bad bad thing, Ms. (Y/l/n)." Hiro shakes his head. You giggle but it was cut short by the lips of the man above you. This was no sweet, innocent kiss though. It was rough and raw, something you guys hardly ever did, simply because you weren't ready for it. You tangle your fingers into his hair and your back arches, so your body was as close as it could possibly to him. This was a whole new side to Hiro that you were liking abit. 

   "(Y/n)..." Hiro mumbles in between kisses. You were getting so into it and judging by the bulge in Hiro's pants, he was too. "(Y/n) wait..." He pulls apart from you and locks a gaze with you. 

   "Really? Licking? I did not peg you to be the kinky type Hiro." Your voice cracks and you let out a loud yawn. You were then attacked by a warm object touching your lip, making you sputter out. You jolt up suddenly, when your head collides with another.

   "Ow!" You and Hiro both groan while rubbing the spot that had been hit hard. 

   "Hiro what the hell are you -" early morning anger rises in your chest but then little tiny barks finally reach your eardrum. You look at Hiro, and he's smiling at you sheepishly while running his head simultaneously. 

   "Surprise!" He says weakly, wincing at the pain of his head. Little Foxx comes bounding over to you, as well as Baymax. 

   "I sensed a sign of distress, is everything alright?" Baymax questions while looking between the two of you. But your jaw has gone straight to the floor as the little puppy prances up your chest to get a better chance of getting attention. "An unknown specimen has also been detected. Shall i terminate it?" Baymax tilts his head, lifting a finger at Foxx.

   "No! No no Baymax, it's okay. It's a puppy and his name is Foxx. He's mine and (Y/N)... That is if she wants." Hiro says carefully, looking over at you. Your mind still has not processed the last minute. Suddenly something into you clicked, and you hopped up in excitement. A scream fills your lungs as you lunge at Hiro, koala-ing him in a hug. 

   "Thank you thank you thank you thank you." you repeated over and over again, and kissed every place available on Hiro 's face. Hiro was so glad you were happy about all of this. A content, Happy sigh escaped him while you were too busy shouting for dear life. Foxx yapped in protest, suddenly no attention was being put on him. 

   "I think Foxx wants his momma's attention..." Hiro whispered into you ear, sending chills down your spine. 

   "I think he wants daddy's attention too." You winked at Hiro seductivley. 

   "Hm daddy - I could get used to being called that." Hiro wiggled his eyebrows at You. You smacked him playfully, and he threw you gently onto the bed. Foxx hopped all over his mum and dad excitedly, licking anything he could.

    "We have our own little family now." Hiro grinned happily, kissing your head. He took this opportunity to take your very first family picture. He takes the opportunity to send it once again to the Group Chat.
