When Katsuki had heard that Momo's house was huge – after all, Zapples would never shut up about it after he'd gone to hers for a last-minute study session before their final exams before summer – he'd expected something sizeable, maybe something like a small manse or manor.
How wrong he was.
"What the fuck is this?!" He exclaimed, standing at the gate with his boyfriend, Shouto, his eyes wide in a stunned stupor.
"The life of the rich…" Shouto muttered to himself, staring down the sheer size of the estate. It stretched more than just a block; it may as well have had its own postal code.
Eyes wide, Katsuki scoffed. "I knew she was little miss prim and proper, but this…" Sticking his hands in his pockets, he scoffed once more. "Go ahead and ring the doorbell already!"
"Sure." Shouto replied honestly, reaching forward and pressing the button on the intercom turning to Katsuki, reaching towards his backpack and lifting the strap back onto the blonde's shoulder. "You gotta make sure you keep it properly on your back, you'll hurt your back if you don't." He chastised him softly.
Scowling, Katsuki swatted the heterochromatic boy's arm away. "I get it, alright!" He growled, stuffing his hands back in his pockets as Shouto sighed.
A sound of static sounded from the intercom, catching the attention of the two teen boys. "Shouto! Katsuki! Welcome!" Momo's voice rang out. "I'll open the gate for you now!"
Katsuki smirked, the image of Momo in her happy bouncy attitude as she stood next to the small piece of equipment. As the gates creaked open, he started moving forward, heading up the road, taking in the sunlight. It hadn't been too long since the three of them had started dating, and whilst it hadn't been really smooth sailing so far – Katsuki's habit of being jealous around his boyfriend and girlfriend when they were with each other and not him was causing him to feel his jealousy flare up, much to their dismay – but even through the roadbumps, they were all extremely happy with one another. Whilst Katsuki wouldn't admit it, he was completely head over heels for the two of them, to the point that choosing between them was impossible for the fiery blonde.
He was infinitely grateful that, when he'd suggested they try a relationship, the three of them, they'd agreed, though not without some hesitation. He was even more grateful that neither of them had decided to mock him for the display he'd put on in the midst of making his proposition – he imagined that the likes of Racoon Eyes wouldn't let him live it down if she'd been there.
Glancing lazily over towards the dual-quirked boy, Katsuki let his mind wander. Initially, he'd been livid with him, his inferiority complex taking full control of his feelings for his classmate. But, as he better got to know the so-called prodigy, he learned that he was just socially awkward, most likely as a result of his upbringing.
He hadn't asked yet what he'd been through, but Katsuki has a horrible feeling it had to do with that nasty scar that covered his face.
"Ah." Shouto gasped, his eyes widening slightly, prompting Katsuki to look forward once more. There, stood in the entryway to the, frankly, ridiculously massive mansion, was Momo. She'd chosen to wear something rather comfortable, a simple button down top with a knee-length white skirt, paired well with a pair of black slip-on shoes which wouldn't look out of place in an office. It was a far cry from the casual attire that both Katsuki and Shouto, with Katsuki choosing to wear a zip up hoodie, a plain t-shirt and the first pair of jeans he could find. Shouto on the other hand, had worn something fairly similar, but his jeans were in much better state than Katsuki's, and he'd chosen to wear a shirt on top of his t-shirt.
As Katsuki took in the sight of his girlfriend, his heart stopped briefly – she had a talent for doing that. He'd always known she was drop dead gorgeous, ever since he'd first seen her, but that wasn't the only reason why he'd fallen for her. The fact that she could actively hold her own against him, not necessarily in a fight, was the fact that he fell for her – she was more than happy to give a verbal retort of her own to any of Katsuki's, the sassy attitude being a massive magnet for the hot headed teen.
"Welcome!" She repeated as they drew close, her hair beautifully plaid into its usual ponytail. "Please, follow me – I've got the dining room set up and ready for our study session!"
"Is this really necessary?" Katsuki complained, sticking his hands in his pockets. "I study well enough on my own!"
"Yes, but we'll study better together!" Momo replied, turning towards the inside of the house, leading them in. "Besides…" She muttered, her voice becoming as quiet as a mouse's, "…I wanted to spend time with the two of you."
Katsuki immediately felt his face flush after hearing the declaration of hers, hiding his face in his hand. "…s'okay." He replied, keeping his gaze firmly locked on the floor.
Shouto, on the other hand, kept his aloof face the same as always, but evidently he'd subconsciously activated his quirk, as the left side of his face suddenly lit up in flame.
"Shouto!" Katsuki shouted, grabbing onto his face. Such an action would normally have burnt anyone else, but due to Katsuki's quirk, his head resistance in his hands was somewhat higher than normal, so it felt only slightly hotter than a candle to the explosion quirk user. "Get a hold of yourself!"
"Ah…" He replied, deactivating his quirk. "Sorry, I just…" He paused, glancing downwards for a moment before nuzzling his cheek into Katsuki's hands. "Your hands are… really gentle, Katsuki."
As though Katsuki's face couldn't get any redder, he retracted his hands, averting his gaze from his lovers as he covered his face once again. "…shut up." He murmured quietly, mostly to himself than either of the two standing next to him.
Momo smiled, reaching forth to grab their hands, interlocking their fingers with hers. "Shall we go?"
Whilst Shouto gave an earnest response, Katsuki merely nodded, letting Momo lead the two of them by the hand through her mansion, firstly through the grand entryway, up the extravagantly crafted stairs before guiding them both down one of the many hallways before finally stopping before the doors.
As she let their hands go to open the grand doorway in front of them, Katsuki let the feeling of her slender fingers linger on his hand for a moment, finally lifting his head as the doors opened, taking in the sight before him. Given the size of the estate, he should've expected that the 'dining room,' as Momo called it, would've also been sizeable, but evidently, he wasn't fully prepared for what to expect. Adorned on top of the grand table, which stretched from one end of the room to the other, was an exquisitely crafted tablecloth, a flowery pattern etched into every inch of the material. At the far end, their study session had clearly been set up – a few whiteboards had been positioned at angles, one for each of them, it seemed. In the centre of their study area awaited a stack of treats, such as biscuits, muffins and small slices of cake.
"…isn't this a bit much for a study session?" Katsuki eventually spoke, still absorbing the room around him as he padded towards the allocated area.
"W-well!" Momo spoke, her cheeks flushing abashedly. "I just wanted us to enjoy our time together!" She explained, making no effort to hide her flustered expression.
"The life of the rich…" Shouto murmured again, his hands in his pockets.
"A-anyway!" She continued, sitting down. "Shall we get started?"
Grunting, Katsuki dropped his bag at the side of his chair, opening his bag as he pulled out his notebook, setting it on the table before turning it to a fresh page. As he grabbed a loose pen from the bottom of his bag, he turned to the two recommended students. "So, what are we starting with?" He asked with a grunt.
"Well, I was thinking that since we have an assignment based on the fundamentals of heroics, we'd best start by making sure that we're all up to speed on them." Momo explained, grabbing her glasses that she tended to wear when she was teaching, pushing them into place.
"Hell no!" Katsuki protested, small explosions going off in the palm of his hand. It was his way of trying to show that he wasn't afraid to use his quirk, but against Momo, who was used to his hot-headed attitude, it did little to impress her. "There's no need! We're all top of the class, I think it's safe to say we all know the fundamentals!"
"True enough, Katsuki." Momo relented for a moment, "But even the pros can make fundamental mistakes in the heat of the moment, thus it is important for us to make sure that we truly understand them!" She explained, a fierce expression donning her face.
"I'm telling ya, it's a waste of time! We'd be better nailing down the new shit, rather than wasting time on stuff we already know!"
"Katsuki, I'm not relenting on this." Momo declared, crossing her arms, her ponytail flicking slightly at the motion.
The two continued to glare at each other across the table, neither blinking for fear of showing any signs of relenting against each other.
"I'm okay with whatever." Shouto spoke up from his position between the two of them, unsure of how to handle the situation.
Glancing an eye towards the dual-haired boy, Momo sighed. "Fine, but only if we make sure to at least ascertain that we all know the fundamentals beforehand."
Grunting in defeat, Katsuki nodded, twirling his pen in his hand as Momo stood and walked over to her whiteboard, grabbing the pen.
"Right then, let's begin!" She said, suddenly giving off a bouncy aura, showing how much she was enjoying the prospect of playing teacher. It was truly contagious, as even Katsuki felt his expression soften as she saw the pure excitement radiating off of her.
"Right, that'll do for now." Momo announced, placing her pen down on her notebook, stretching her arms above her head.
From his position next to his own whiteboard, covered in some scribbles about the importance of prioritising when undergoing a rescue, Katsuki scowled. "What are you talking about? We can keep going."
This time, it was Shouto's turn to speak up. "Katsuki, we've been going for about three hours now, let's just take a quick five-minute break, at least."
Whilst the explosive boy would normally attempt to retort, he found that, in his experience with the heterochromatic boy, he genuinely struggled to say no to him.
"…fine." He replied, placing the marker down on the table as he began to wander towards one of the grandiose windows that allowed bountiful rays of sunlight to shine into the sizeable room.
Even with him having been here for a few hours already, he still wasn't used to 'the life of the rich' as Shouto had put it. It truly was incredible just how massive this place that Momo called 'home' was. It seemed to just stretch on and on to the horizon…
As his eyes wandered, a glimmer of blue caught his eye – positioned just outside of the mansion, within walking distance, was a sizeable swimming pool, easily bigger than the standard that one would see at a public pool, and certainly bigger than the Olympic size pool they had at UA. Given a rough estimate, it looked to be at least a hundred metres long, much longer than any standard swimming pool, and adorned at one end was a small slide, just next to a diving board.
Curious what Katsuki was looking at, Shouto wandered over next to the usually grumpy boy, looking down at the sheening blue water. "I didn't know you had a pool." He stated, bluntly.
Perking up, Momo smiled. "Yes, we've had it for a while! On days like this, it's so relaxing to go for a swim, don't you think?"
"…then why don't we?" Katsuki offered, his hands still in his pockets as gaze softened.
"That's an excellent idea!" Momo replied excitedly, clapping her hands together.
"I don't have my swimming trunks with me, though." The scarred boy said quietly, looking down in disappointment.
"Not to worry!" Momo piped up, rolling up her sleeve as she activated her quirk, producing a set of swimming trunks decorated with a flame design going up the left leg – whether she'd done that intentionally given Shouto's quirk or not was a mystery to Katsuki. "I shouldn't really be producing clothing as it somewhat indirectly affects the market, but if it's only one or two pieces, it should be fine!"
"Then, can you make some for me too?" Katsuki requested, turning to face the two teens.
"Of course!" She replied, utilising her quirk to produce another set of swimming trunks, this time, it was black with small explosive dots placed erratically around the article of clothing.
'She's doing this on purpose.' Katsuki mused, an amused puff of air exhaling from his nose as he murmured his thanks to her.
"Right, I'll go and get changed and meet you out there." Momo declared, standing up and heading towards the same hallway they'd been down before. "You guys can get changed in here, if you like."
"Sure." Shouto replied instantly, nodding.
Katsuki, on the other hand, felt his face heat up for a moment before nodding, with Momo departing. Whilst he was far from self-conscious – if he was being honest, he knew how good he looked – he was a little awkward about the thought of potentially seeing his lover in a state of undress.
His gaze glanced over to Shouto, his face neutral as always as he slipped off his shirt, dropping it on one of the many chairs in the dining room before grabbing onto the hem of his shirt, lifting it up over his head.
Katsuki had seen the prodigy's physique a few times before now, but those were before he realised he was head over heels for him – right now, only a few short metres away from one of the objects of his affections, he felt like he was about to blow a fuse.
Desperately trying to hide his embarrassment, Katsuki turned away, stripping off on his own, chucking his own clothes on his own chair.
Part of him desperately wanted to peek, to keep looking as Shouto got changed, but he knew that it would be for the best if he didn't – the last thing he'd want was for either of his beloveds to find out.
And he never wanted to be associated in the same category as their perverted classmate.
Slipping on his own trunks, he turned to see that Shouto was also ready to swim. "You ready?" He asked, hands on his hips.
"Y-yeah." Katsuki flushed, holding out his hand. It wasn't often that Katsuki wanted to hold hands with, well, anyone, but he felt the need to now.
Giving a soft smile, Shouto reached forward and gently took Katsuki's calloused hands, giving him a slight squeeze for reassurance.
As the blonde boy led the other teen out of the room, a thought crossed his mind.
"…how are we supposed to find the pool?"
The dual-quirked boy blinked, thinking. "Uh, I suppose we head down towards where the pool is?"
"Yeah, but this place is massive! We could get lost!" Katsuki explained, still keeping hold of Shouto's hand.
"Ah, Katsuki! Shouto!"
Turning their heads towards the source of the noise, both Katsuki and Shouto felt their faces heat up, an exuberant shade of red donning both of their faces.
It wasn't like it was the first time they'd seen her in a swimsuit – she'd worn one plenty of times for PE, when they'd been in the swimming pool. However, this was a far cry from the school swimsuits, which were more like leotards in how they were shaped.
This, on the other hand, was an outright bikini – a fairly modest one, if Katsuki was being modest, but it was still more adventurous than he'd expected. Whilst it covered everything important with some room to spare, it was enough for him to be aware of her gracious curved and exquisite physique. The white colour scheme that it offered, too, wasn't helping either, as it seemed to further highlight everything that drove others, especially the class pervert, crazy.
And it was clearly working on the resident explosive teen of 1-A too.
"Follow me! I'll lead you to the pool!" She exclaimed, pointing down the stairs, her bouncy energy still going strong, even after three hours of study.
The two boys nodded, following her down the stairs as she led them down another hallway, just off the left of the grand entrance hall, before hopping through what appeared to be a sizeable laundry room before opening the door to the outside, the warm rays of sunlight initially blinding the trio before their eyes adjusted.
The pool was even bigger up close – looking at it from above was certainly a sight to behold, but actually seeing it on ground level made it look massive, like it stretched out for miles and miles.
"Right, let's go!" Katsuki yelled, excitement coming through in his coarse tone as he dashed towards the water.
"Katsuki, don't run!" Momo warned, but it fell on deaf ears as he jumped straight into the pool, water splashing in every direction. Sighing in defeat, Momo let Shouto's hand drop to his side, sitting down on the side of the pool and letting her feet dangle in the water for a moment, savouring the feeling of the cool, refreshing water running over her feet, any feeling of tension seemingly ebbing away.
Shouto, on the other hand, headed over to the diving board, bouncing lightly on it for a moment as he got a feel for how springy the board was.
As Katsuki watched, he fully expected him to bellyflop into the water, but was merely stunned as Shouto bounced once, twice, and then a third time before pulling off a front flip, executing his dive perfectly.
"10 out of 10!" Momo declared from her position on the side of the pool, clapping to herself.
Katsuki smirked, lifting his own hands out of the water to clap himself as Shouto came back up to the surface, gasping for air.
Smirking, Katsuki ducked his head under the water, swimming towards Momo's location, seeing her feet dangling in the water. Without surfacing, he quickly grabbed her leg, pulling her at an angle which would ensure that she wouldn't hit her head on the side of the pool, dragging her into the water.
As Momo surfaced, her face initially etched with a scowl, it softened as she smiled at the two boys in front of her, swimming over to them and wrapping her arms around their necks, pulling them both into a hug, which they both reciprocated.
As Katsuki enjoyed the hug between the three of them, he took a moment to glance at both of his lovers - sure, they'd only just started their relationship, but Katsuki wouldn't rather spend his time with anyone else.
And it's complete! I had a lot of fun writing this, so I hope you all enjoyed!
Don't forget to review! Until next time!
