The entire group came bursting out the doors, cheering for Hiro's success in enrolling into the San Fransokyo Institute of Technology, thanks to his amazingly new invention. The showcase was still going, but after that presentation, they already felt like celebrating.

Cass: "Alright, geniuses, let's feed those hungry brains. Back to the cafe, dinner is on me!"

Y/N: "Alright!"

Fred: "Yes! Nothing is better than free food!"

Tadashi: "Aunt Cass? We'll, uh... we'll catch up, okay?"

Cass: "Sure. I'm so proud of you!" *hugs Hiro, then Tadashi* "Both of you... and you too." *looks at you*

Y/N: "It's part of being me."

While the others went to celebrate, you stood behind with the brothers, overlooking the campus with Tadashi.

Hiro: "I know what you're gonna say. "I should be proud of myself, because I'm finally using my gift for something important."

Tadashi: *sly smug* "No no, I was just gonna tell you your fly was down for the whole show."

Hiro: "Ha ha, hilarious."

Aaaaand, he looks and it's down. He zips it back up before looking to Tadashi and nudging him on the arm. After that embarrassing little mishap... Tadashi reset the mood by saying...

Tadashi: "Welcome to nerd school, nerd."

Hiro: "Hey, I um... I wouldn't be here if it wasn't or you. So, y-you know, thanks for not giving up on me. Both of you."

Y/N: "You're welcome, Hiro."

But the moment is short-lived when the sound of an alarm goes buzzing and people can be heard screaming in terror. You and Tadashi go and follow the sound to the showcase. Everyone was running out of the burning building off to safety.

The three of you go to see what's happened, but you already the whole gist of the situation.

Tadashi: "Are you okay?"

Student 1: "Yeah, I'm okay. But Professor Callaghan is still in there."

Y/N: "WHAT?!"

Tadashi doesn't hesitate to go to save him, but Hiro tries to stop him from going in there.

Hiro: "Tadashi, no!"

Tadashi: *looks at building, then back to Hiro* "Callaghan's in there, someone has to help."

And he breaks free of his brother's grip and rushes inside while his hat falls off, but you also chase after him.

Hiro: "Y/N... NO!!!"

Once inside, you spot Tadashi and notice the flames were about to consume the poor guy. The flashback of what happened to Scar flooded your mind and all you could think was...

Y/N: "NO! I WON'T FAIL AGAIN!!!"

You rush in front of Tadashi, whip out your keyblade and activate your reflective barrier around the two of you, shielding you both from the explosion and the raging inferno. You let out a prolonged battlecry trying to keep your shield up until the flames would die out.

You're not sure how long the explosion lasted, but thanks to your quick thinking... Tadashi was saved from certain demise. The barrier subsided, but you still had to get Tadashi outside, or else the two of you will wind up dead from smoke inhalation.

Tadashi: "Y/N... what was..."

Y/N: "No talkie-talkie... Hiro needs you!" 

You carried Tadashi over your shoulder and rushed out the building, then making your keyblade disappear into thin air. As soon as you saw Hiro, he rushed towards you with worry.

Hiro: "Tadashi... is he?"

Y/N: *nods, sets him down* "He's alive. We barely escaped with our lives, but... we couldn't find or... even save Callaghan."

But you knew that was far from the truth. You knew he was still out there, but what's most important right now... is that Tadashi is alive... and Hiro still has his big broher. He couldn't stop himself from lunging at his big brother and hugging him tightly.

[timeskip because REASONS!!!]

Some time after the incident, the students of the institute gathered around to hold a memorial for their lost professor. It was a sad day for everyone who was ever close to Callaghan. But, thankfully for Hiro and Cass, they still had Tadashi. 

Tadashi: "I should've been quicker. If only I wasn't so weak... or so slow... I could've saved him!"

Y/N: "Tadashi... you shouldn't beat yourself up about that. You tried, that's all anyone can do." 

Tadashi: "But he should've been saved!"

Y/N: "He's GONE, Tadashi! How do you think he'd feel if one of his prized students was lost in the fire with him?! Huh?! How do you think Hiro would've felt if he lost the only brother in his entire life, after losing his own parents so long ago, huh? YOU TELL ME!"

Tadashi was taken aback and even Hiro and Cass had to agree with you on the subject at hand.

Cass: "He's right, sweetie. You have to think about what you still have and not what you've lost. You're still alive, you're still able to come home to me, your aunt and your little brother. Can you imagine how heartbroken Hiro would be if he lost you? I already lost my sister and brother-in-law, so please don't make me lose you, too!"

With a sigh of defeat, Tadashi eventually gave in. After all, he can't deny the truth no matter how hard he tries. Callaghan is gone (at least that's what everyone thinks now) and it was out of Tadashi's control to save him, but he still has a family, friends and a home.

So, it is now Hiro's first day at his new school. He and Tadashi leave the house via the moped while you stayed behind with Cass. She had set up a guest room for you after she found out you saved Tadashi and this was one of her ways of paying you back.

Right now, you're up in the guest room, stretching your body after a goodnight's sleep and about to help set up shop for Cass. But as you head for the door, Cass comes in, blocking your way.

Y/N: "Oh, hey Cass. What's up?"

Cass: "Nothing, just thought I'd have a talk with you. Mind if you have a seat on the bed for a moment please?"

Y/N: "Sure, I don't mind."

You retreat to the bed and sit down at the foot of the bed and she sits down next to you, then looks you in the eye.

Cass: "Y/N... I know I've said this over a hundred times, but still... in the short time we've known you ever since you got here, you've done nothing but help my family in times of crisis. First, you save Hiro from getting hurt by some thugs when he went out bot-fighting, you help him with his science project for the showcase and now... you've saved Tadashi from certain death and I cannot thank you enough."

Y/N: "That's part of what I do. And you know what... I'd do it all again if I was given the chance." 

Cass: "I know you would. But... you never expect anything in return, even if we offer you stuff."

Y/N: "That's because I go by another creed as part of being a hero... it's save... or be saved."

Cass: "And you saved me from a major heartache. That's why I am insisting on paying you back tenfold for all you've done."

Y/N: "Insisting? How?"

Cass: "First things first."

The gorgeous cougar then gets off the bed and goes to close the door before locking it and then turns back, walking towards you. Only this time... she walks towards you slowly.

[LEMON INCOMING!!!]

She then starts removing her black shirt and undoes her skinny jeans before pulling them off and tossing them aside. Now all she has on her is her black, lacey bra and panties. Words cannot begin to describe how hot this woman is, not even your imagination can compare.

Y/N: "Whoa... Cass, you're... you're beautiful!"

Cass: "You think so? Even if I'm 33 years old?"

Y/N: "For you, age is just a number." *thinks* "Besides, I'm probably somewhere in my mid-twenties even though I look 19."

She felt flattered by your praise and then sat herself down on your lap and soon, her lips met yours in a passionate embrace. 

Y/N: *thinks* "HOLY SHIT!!! This is fucking awesome!!! Okay... Okay, don't lose your shit, just treat her like a lady."

You calm down and then start to remove your own clothes from your body until you're only in your boxer briefs. 

Y/N: "It wouldn't feel right if you were the only naked one."

Cass: "How chivalrous. Come here, you."

She then hoists you up from your spot and resumes kissing you while standing, then she rubs your crotch through the fabric of your underwear, moaning softly. Your mind is racing, but you hold it together and grab hold of her sexy, plump ass.

Cass doesn't mind you getting handsy with her and just pushes herself into your body more. Tongues start dancing and she's now on cloud 9 and refuses to come back down. You then hoist her up by the waist and bring her onto the bed with you. The two of you lay there, looking deeply into each other's eyes, grinning.

Y/N: "Anyone ever told you you have a beautiful smile?"

Cass: "Oh, stop it. Has anyone ever told you you're such a helpless, perverted flirt before?"

Y/N: "You did just now. But I can't help but wonder who's more perverted, me... or you."

Cass: "Hmm... why don't we find out?"

This horny aunt then reaches into your underwear and grabs hold of your stiff, hardened meat pole and starts jerking you. Her soft, tender hands feel so good on your skin, but you won't let her outdo you, so you reach into her panties and finger her womanhood.

She inhales, moaning softly as you pump your fingers in and out of her wet canals while you keep groaning from her soft hand stroking that ferocious beast down there. It's a good thing with the boys at school and the shop closed, no one can hear you two.

Thank to your experience with all your wives, you even went for her clit and began rubbing it with your thumb. Cass bit her lip from how sensitive it felt having her love button played with and almost lost rhythm, but kept stroking you to no end.

You can feel her juices flowing out of her nether regions like a leaky river dam about to break. Cass couldn't believe just how good you were with your hands, pleasuring her like a pro. 

Now she had to show you her gratitude... and she will pay you back tenfold for everything... right here and right now. So, Cass lets go of your throbbing manhood and then grabs the hem of your boxer briefs and pulls them off without ripping the fabric. She then straddles on top of you, smiling down at you with her seductive stare.

Cass: "Time for your prize~."

Y/N: "Bring it, beautiful."

Oh, it's been brought. she moves the bottom part of her panties to the side, exposing her womanly area and then slowly sinks down, almost taking the whole thing. She gasps from how huge you are while you're gripping the sheets from how tight she is. Your hips thrust upwards on their own, jamming that beast further inside.

Cass: "Ahh!!! So big! Mmmm, someone's liking their prize."

Y/N: "Not like... LOVE!"

Honestly, she can't help herself with how kind and honest your words are and she soon rides your massive pole. She doesn't take her eyes off you, not even for a second. She just keeps moaning and sucking in your meat rod into her deepest depths. Cass is even leaning over you just to give you a perfect view of her.

You can't stop yourself from running your hands althrough her body, loving every inch of this sexy, hot cougar. You then stop at her lovely ass and spank those cheeks. She yelps and gasps, but then giggles seductively, enjoying a little rough play. 

This turns her on some more, causing Cass to speed up her rhythm and squeeze you tighter. You can practically hear her giggling like she's enjoying dominating over you. How quickly she forgets who's really at the top of the food chain here.

In a swift motion, you switch positions with her and now, you're the one who's dominating her, plowing her tight quarters. Cass lets out more pleasurable moans from this. She can feel you reach deeper into her depths, knocking on her entrance repeatedly.

Cass: "Goodness! I'm... I'm gonna lose it! Gimme more, baby!"

And you give it to her good. She locks her legs around your waist, keeping you locked in a mating press position. She gets tighter and wetter from the hearing the sounds of your grunting and growling, turned on by your powerful dominant side.

Her mind feels like it's going blank. She can't think straight and can feel herself becoming lost within the pleasure. You... are already far gone and nothing's gonna stop you from breeding her, not with the way she pushed all of your buttons so easily. 

Your hips move faster on their own. Your head slowly arches upwards, you take in deep breaths and Cass is moaning up a storm, too horny and too powerless to stop you.  In a matter of moments, you eventually hilt balls deep into her deepest areas and blast your breeding milk into her warm love chambers. Cass lets out a pleasurable moan, stiffening up and cumming hard on your crotch.

This had to be, by far, the best sex she's ever had. But man, the stream of man milk kept flowing inside of her. You bury your face into her soft, warm bosom and she holds you there. Every time your shaft throbs, your hips thrust deep and pump more inside her. This goes on for a minute and a half before you eventually run out.

She lets you go and you collapse right next to her, panting heavily from that amazing experience.

Y/N: "I.... will definitely... remember this."

Cass: *satisfied* "So will I. But... it's best we don't let the boys know... at least, not right away."

Y/N: "Yeah... I agree, not a word.

[Lemon over, timeskip now.]

It's now been a few weeks since Callaghan's funeral, Tadashi was saved and... your fun time with Aunt Cass. With the boys currently in school, you were left at home to do nothing but keep the house clean and help around the cafe from time to time. At the moment, you decided to help straighten out the boys' rooms.

While tidying up their rooms, you glance at Hiro's old megabot and have a little looksie at the little guy. Funny how a young teen can go from a bot-fighter to a bright student in one night, all thanks to the influence of his clever older brother.

Just then, the bot's legs falls on your toes and you exclaim in pain since you don't have your shoes on. 

Y/N: "Ow! Jeez that hurt!"

Oop and just like that, Baymax has activated. And the funny, huggable marshmallow slowly makes his way out of Tadashi's room and over to you with his cute waddle.

Baymax: "Hello, I am Baymax. Your personal healthcare companion."

Y/N: "Oh, hey there, big guy. I forgot, Tadashi had brought you home some time ago."

Baymax: "I heard a sound of distress. What seems to be the trouble?"

Y/N: "I was just checking out Hiro's old bot and its legs fell on my toes and it hurt a bit, but I'm good now."

Baymax: *displays digital screen* "On a scale of 1 to 10, how would you rate your pain?"

Y/N: "I'll just go with 1."

Baymax: *goes to touch toe* "Does it hurt when I touch it?"

Y/N: "No, it doesn't." 

Baymax: "I will now scan you." *scans you* "Scan complete. You have sustained no injuries. Yet your brain waves indicate you have a few things on your mind right now. Diagnosis: anxiety."

Y/N: "What?" *thinks* "Damn, he's good." *aloud* "Right, I'll just get back to cleaning up."

And so you do, but Baymax isn't done.

Baymax: "You can properly treat your anxiety by; staying physically proactive, eat a healthy diet, avoid any and all smoking and alcohol, prioritize plenty of sleep, learn relaxation techniques."

While he's rambling on, you noticed something under the bed moving and go to grab it... only to discover Hiro's only remaining micro bot.

Y/N: "Baymax... come and look at this. It's one of Hiro's old microbots, it's acting sort of strange."

You then put the bot inside a little plastic container.

Y/N: "It looks like it's being drawn to the other microbots. Baymax, Hiro and Tadashi won't be back home until later, I'm gonna need you come with me to investigate."

Baymax: "Will this help improve your anxiety?"

Y/N: "That and it'd definitely help with my curiosity. But first things first... I gotta clean up the boys rooms."

And just like that, both you and Baymax left the shop after minutes of cleaning up the place. Naturally, you made sure to keep Baymax from walking into the busy streets and headed off to your destination the safest way possible and eventually arrived and this old, abandoned warehouse... where shit's about to hit the fan.

Y/N: "Looks like we found our destination. But the door's locked, we'll need to find some other way to get inside."

Baymax: *looks up* "There is a window."

Y/N: "Good eyes there, Baymax. Now, hold on tight."

You grab Baymax and mega jump to the window and crawl through it.

Baymax: "Please exercise caution. A fall from this height could cause you bodily harm."

Y/N: "I will. Thank you, Baymax."

Once you're inside, you then try to help Baymax in, but his body is too big, so he lets out some air from his suit. You're not gonna lie, it sounds kinda funny when he deflates. Luckily he's now thin enough to fit through the window and you pull him in.

Baymax: "It will take me a moment to re-inflate."

Y/N: "Take your time, I'm gonna have a look around."

So, while the big balloon buddy re-inflates himself, you keep looking around the rusty, abandoned warehouse. But this time, you're prepared and bring out your keyblade.

Y/N: *thinks* "He's here. I know it."

A little further inspection around the place and you eventually find a little factory that's mass producing Hiro's microbots. You even find a barrel full of them, which only means 1 thing.

Y/N: "I'm gonna need some backup."

You then turn to a map on the wall, detailed on what the microbots will be used for, but...

Baymax: "Y/N?"

Y/N: *startled* "Oh! Baymax, you came outta nowhere. Listen, we gotta get outta here. Hiro and Tadashi have to know that someone is making more if Hiro's microbots! And if we don't get out of here right now, we might just end up as their..." *hears clinking* "...victims."

You look down at the container with the one microbot and it's frantically moving south in the thing and sure enough... thousands upon thousands of other microbots begin assembling from their bins behind you and Baymax looks up with his usual...

Baymax: "Oh no."

Y/N: "Baymax... we're getting outta here, now!"

And grabbing Baymax yet again, you demonstrate your powers of parkour and rush around the facility, leaping off the walls and the ceiling and onto the warehouse catwalk. But that's where you spot the infamous Yokai, who's controlling the bots.

Y/N: "YEET!"

You turn back to head out the window, Baymax is still in your grasp and you have him riding on your back since he's not fast. However, when you do reach the window, the loveable marshmallow gets stuck again and you try to force him out, only to get flipped and now you're outside, tangling from Baymax's feet.

Y/N: "Whoa!!! Baymax INCOMING!!!"

Baymax: "Y/N?"

And the microbots then push the inflatable robot out of the window, along with you, too. Baymax hugs you close to him and cushions your fall, using his own body.

Y/N: "Thanks Baymax. Let's go! Hurry! Back to the cafe, the boys'll be back home real soon!"

You carry Baymax on your back again and this time, you travel back to the cafe parkour style, not wanting to waste time.

It is now early evening and you just arrived at the house. Behind you is... a drunken Baymax since his batteries are low.

Y/N: *whispers* "Okay, Baymax. Listen... we're gonna charge your batteries and then we'll tell the boys what happened, but don't say anything around Cass or she's gonna flip out."

Baymax: *drunk* "We jumped out of window."

Y/N: "No! Quiet! Shh!"

Baymax: *drunk, quiet* "Shh! We jumped outta window."

Y/N: *snickers* "You silly bot, you don't say that around Cass! Shhhhh!"

Baymax: *drunk* "Shhhhhhh!"

You're trying your hardest not to laugh, but Baymax acting all drunk when he's low on batteries is just too funny and adorable. So, you tip-toe up the stairs and Baymax... tries, but falls flat on his face, this time causing you to snicker even louder. He's not doing you any favors by shushing you in his drunken state again.

Cass: "Y/N? Is that you?"

Y/N: "Yeah, it's me. I uh... I went out for a little stroll in the city after cleaning up the shop and the house, too."

Cass: "Aww, thanks. You're a real lifesaver. Oh, yeah, I almost made some chicken wings if you're feeling hungry."

ENTER DRUNKEN BAYMAX

Baymax: *drunk* "WEEEEEEEeeeeeeeeeeEeeeeeeeee!"

You get startled and then hide him, trying not to laugh again.

Cass: "Yeah, "Wiiiings! Alright, ge ready to have your face melted, because we're gonna feel these things tomorrow."

While her back was turned, you moved Baymax quickly up to the boys room as quick as a flash before coming back to grab a plate of Cass' delicious chicken wings.

Y/N: "Mmm, delicious! I'm gonna go ahead and take this upstairs, if that's alright with you."

Cass: "Sure, no worries. Oh and the boys are looking for you, you might wanna go see them."

Y/N: *thinks* "So it begins." *aloud* "Alrighty then."

Taking your plate and hugging Cass, you then head upstairs to the boys room and are then confronted by the dynamic duo.

Tadashi: "Mind telling us why you took Baymax with you out in the city while we were away?"

Hiro: "Oh and... thanks for cleaning our rooms."

Y/N: "First off, you're welcome and... you're not gonna believe what Baymax and I stumbled upon and... it's pretty serious."

Tadashi: "How serious?"

Y/N: "Not sure how to put this, but it's deadly serious."

Something tells them what you have to say can't be too good, but you had their attention and they were all ears.

[A/N: How's that? Your long-awaited Cass lemon and a drunken Baymax, followed by a major cliffhanger. I have worked my butt off trying to make this chapter. Hope you all enjoy it and I hope you're glad to know... Tadashi has survived.]
