Chapter Text

Bowser couldn’t find it in himself to let Luigi fall asleep such a complete and utter mess. He carefully carried the little plumber to the adjoining bathroom and began to run a very nice warm bath…not really warm enough for his liking, but he was not in the mood to boil his new mate alive.

Luigi kept blinking lazily, so close to drifting back off to sleep, that Bowser was sure he was going to fall asleep any minute.

And he did.

Bowser simply hefted his human up in his arms, and entered the filling tub to clean them both off.

When everything was cleaned, and Bowser was more than happy with putting Luigi in bed, he had the linens changed and carefully put him into the middle of the massive bed. He pulled the soft comforter up, tucking Luigi in, and smiling warmly as he watched his mate snuggle into the warm of the covers.

He needed to speak with Kamek immediately. They had to get in front of this now or else the Mushroom Kingdom might retaliate seeing as the human he stole away was the other half of the annoying Mario duo.

–

Kamek was not happy at all. He kept lowering his glasses, his squinted eyes narrowing impossibly, as he tried to convey his displeasure to his surrogate son. Bowser actually looked a bit sheepish, but was resolute in his decision.

“He’s going to stay here, Kamek. That’s the end of it.”

“Does HE know this?” Kamek raised a brow, smacking his lips in annoyance.

“I mean…He will! He just has to…you know…wake up so I can tell him.”

Kamek slapped a hand to his spectacle face and groaned loudly. “Sire!” he groaned, able to fit SO MUCH annoyance in that single syllable that Bowser was temporarily too stunned to speak. “You cannot just take in a human that meets your fancy!”
“But the princess…”

“Was always a heavily political move!” Bowser huffed at this, crossing his arms over his heaving chest. “This is one of those plumbers! The ones who imprisoned you!”

“And took care of me…”

“Out of guilt I expect.” At that statement, Bowser growled at him. He wanted to stomp and throw a tantrum, but knew that’s what Kamek expected. “Regardless, you can’t just bring home a human and make it part of the family. It’s not a koopaling…It’s a HUMAN–a citizen of the Mushroom Kingdom!” Kamek's voice was rising, making Bowser flinch before he finally had enough, stamping his foot down enough to crack the stone floor.

“ENOUGH! Kamek he stays…period…he has to…”

Kamek, sensing he was missing something important, had finally moved closer, large spectacles glinting in the fire light as he finally took in something that had been hidden by shadows. There…right at the juncture of throat and jaw…teeth marks. He gasped, jumping back and pointing his wand up at Bowser, spluttering indignantly. “You—you BOUND yourself to him! ARE YOU MAD!?!?!”

“I AM KING AND CAN DO AS I PLEASE!” He roared, fire spilling from his throat as he seethed. “Kamek, you forget your place,” he growled dangerously. “And I only allow this familiarity because you raised me…but watch yourself, old koopa.”

“Sire, I a-apologize, but-but….” He flailed, unable to stop himself. “ARE YOU CRAZY!? A HUMAN?? A human MALE at that!!!! He can’t even give you an heir!!” Bowser huffed in annoyance, turning and deciding he no longer wanted to have this conversation.

But Kamek followed him out of the throne room.

“He offers nothing to you, Your Nastiness. Please reconsider!! The connection isn’t that deeply rooted–we can still get rid of–”

“No!” Bowser turned, eyes wide and looking down at Kamek in almost…fear?

The old koopa mage was floored. He had never seen that desperation in his king's eyes before. It was new and it frightened him as well. “Sire…”

“I said no, Kamek. I want him here. I LIKE him here…with me. Please–”

The magikoopa sighed, rubbing his face hard enough to knock his glasses around over his beaked snout. He grumbled in frustration. “Very well, very well.” He didn’t miss Bowser’s toothy grin, turning away before he saw too much more. “I will draw up the union paperwork to make your bond “legal”...” He used sarcastic air quotes with his little claws. “But you BOTH have to agree to it and sign it. It’s not marriage, Bowser. You can’t force this.”

The king nodded, watching Kamek leave, the old koopa muttering the whole way back to the alchemy sector.

Bowser heaved a sigh, turning to look at the hall leading to his wing. Now he just had to convince Luigi.

Chapter Text

Luigi stretched, eyes slowly opening to stare up at a canopy that did NOT belong on his bed. It took him a long moment of just staring before his fuzzy brain cleared enough for him to remember where he was.

And the blush that bled across his face didn’t stop at his cheeks and ears, but raced down his neck and collarbone. His hands flew to his face and took a shuddering breath as the previous nights events began to flash across his waking mind.

Bowser and him…he and Bowser…

Luigi let out a nervous little laugh, psyching himself to sit up and take in his surroundings a bit better. Groaning, he pushed himself up, noting how EVERYTHING was sore. Nothing was painful, but his whole body was filled with dull aches and pleasant burns. He shifted his hips and felt more soreness, his hands covering his face again as if it would stop or hide his blush. “Mama mia…” he muttered into his palms, dragging his hands down his face.

He scooted to the edge of the bed, dragging the black sheet with him, and wrapped it around himself as he slid off the soft inviting mattress. Bare feet settled on a warm and soft rug, and Luigi padded quietly to one of the side doors of the massive room, hoping the one he chose was the bathroom.

Where was Bowser anyway? He was a little annoyed that he had left him alone, not even signifying him with his presence after their torrid affair. Luigi snorted at that thought, now even more annoyed that he had gotten annoyed by Bowser’s absence. He opened the door and sighed in relief when he saw the wonderfully large bathroom.

–

Bowser opened the door to his chambers, expecting to see Luigi still huddled in the middle of his massive bed. Seeing the little plumber gone made Bowser almost drop the food tray he was carrying, but he caught himself, rushing to put it on the table by the fireplace before starting to look around the room for his little human. He was slightly panicked now, realizing he hadn’t locked the door while he had been gone, and the Mario brother could have easily slipped out.

Would he though?! After what they shared? Bowser felt the searing flame rising in his throat, a rage that he had never felt before crashing over him at the thought that his human…his MATE…would abandon him and leave–

Bowser suddenly snapped to attention, all anger leaving his body in a cold rush when Luigi opened the bathroom door, shuffling out in his makeshift robe of sheets.

Bowser growled, moving on Luigi before the other man had time to think, large arms scooping him up and holding him close. The human squeaked, trapped within the sheets, and now held against the king like a bundled child. Bowser simply held him for a long moment before making his way to the sofa by his fireplace. He plopped down, Luigi still in his arms.

“Bowser?” came the small voice of Luigi. Bowser tightened his hold for a second before loosening it and looking down at him, eyebrows raising in question. “Everything, ah…alright?” Luigi was looking up at him in fear and surprise and Bowser realized he hated that look. He didn’t want him to ever fear him.

He huffed a bit, a blush staining his cheeks. “I thought you had esc…uh…left. I was worried.” was the tiny, quiet reply. He chanced a look at Luigi and felt his heart leap to his throat. The sparkling blue eyes were looking up at him with such adoration, that Bowser almost had to look away. Almost.

“Really?” The human shifted a bit, pressing himself a bit more into Bowser’s embrace, rumpled hair tickling under his chin.

“Yes really.” he rumbled.

“Why?” Bowser cast a look down at Luigi that clearly said “why do you THINK?”, but it smoothed out into a deadpan glare at Luigi’s cheeky little grin and mischievous sparkle in his eye.

“I regret getting you food, now.”

Luigi gasped, looking at the food tray and back to Bowser. “Aw come on!” He freed his arms and reached up to grab Bowser’s cheeks. “Don’t be like that…I was just messin’.” Bowser exhaled a puff of smoke across the little human. He was going to just brush it off, but the feeling of Luigi’s hands on his cheeks made him melt.

The little touch made him just relax almost instantly. His connection with his human was already noticeable and it made his stomach and chest warm like he had swallowed an entire pepper-up potion. He trilled, his rumble making Luigi smile, and he felt himself falling even harder. Oh to have that smile every day!

He shook off Luigi’s hands, wanting and needing to press his face in the human's neck. He inhaled deeply, his lips ghosting over the bite that he had made. It made him proud.

Luigi giggled and patted his cheeks. “So did you really bring me breakfast?” Bowser gave the mark a little lick, making Luigi shiver, and pulled back to grin toothily down at him.

“I figured you might be hungry.”

“Starving.” Luigi said, his blush deepening as Bowser rumbled again.

Bowser finally released Luigi, settling him next to him on the sofa and reaching over to bring the coffee table closer so Luigi didn’t have to move far. The little human made an excited noise and grabbed the bowl of what looked like oatmeal covered in baked apples and drizzled in honey. Bowser sat quietly, watching him eat.

The king was almost undone by the happy little noises Luigi was making. “Do you like it?”

“E delizioso…” Luigi moaned, licking his spoon. Bowser felt that warmth again in his belly. “Delicious!” he clarified and Bowser was appreciative, though he felt he knew what the man meant even without the translation.

“Good! My chefs are researching human recipes. Do you have any requests or is this something you’d like every morning?”

Bowser was fidgeting, his claws clacking against each other as he rambled.

Luigi had stopped eating, a worried look on his face. “E-every morning?”

Bowser slowly looked at him, dreading the confusion he knew he’d find in those blue eyes. “Y-yes!” His voice wavered only slightly, but he muscled through, getting a bit louder to mask his anxiety. “Of course! You can’t expect to stay here and NOT eat breakfast every morning!” He forced a laugh, not wanting to look at Luigi now.

He could feel it…he could feel the sudden apprehension in the human. He could smell it.

“Am I not going back…I mean, I CAN go back, right?” His voice was pleading.

“Why would you want to?! I have everything here you’ll ever need!!” ‘and I’m here!’ his mind cried out. ‘I’m here and I need you here too!’

Luigi audibly swallowed, his hand moving to touch the mark on his neck before looking up at Bowser, eyebrows furrowed. “Am I a prisoner?”

Panic. Bowser had never felt this panic before and he hated it. He was never scared, NEVER! Why was he feeling this?! WHY NOW!!? ‘SAY YES! SAY YES!!! YOU CAN’T LEAVE ME!’ screamed his brain, but he pushed that part of himself back, clearing his throat. “No, of course not.”

“But you’re keeping me here?”

“Yes!”

“Against my will…”

“No!!”

“Then I can leave…”

“NO!!”

“Okay, I think we need to talk, Bowser.”

“No we don’t! Eat your breakfast!!” Bowser stood up, refusing to look at Luigi who was scrambling to his feet too, tripping on the sheets. “I’ll have Kamek get you when you’re dressed!” And before Luigi could extricate himself from the shroud of linen, Bowser had fled.

–

Luigi stood there, watching the door shut a bit too loudly, gripping the sheets that now hung loosely at his hips. He sighed. This was getting messy already.

He shuffled back to the couch, sitting down with a huff, and began to eat his breakfast again. It was really good. Just sweet enough to satisfy his sweet tooth, but filling enough to be a hearty breakfast. There was also a muffin on the little try and what looked like orange juice. He tried each in turn, realizing how much better it all tasted than the food he was regularly fed in the mushroom kingdom.

It was why he so often cooked for himself instead of letting the Toads do it. He was sure there were those yummy spices in here too…the kind that got him into this mess in the first place.

He huffed out another annoyed sigh…and then groaned, a weird pain erupting in his chest. He took some deep breaths, his heart suddenly pounding like he had gone from 0 to 100 on the anxiety meter. He had no reason to feel like that, and it was unnerving that it had come out of nowhere. He slowed his breathing, finally able to feel like he was in control of his own body again…

That was a weird way to think about it…

Luigi picked at the muffin while he sat and thought about everything going on. Bowser was acting even weirder than usual–he had been sure that he was going to eat him for the stunt he had pulled during that faithful bath time…but he definitely had not. Luigi felt his cheeks heat and pressed his hands to his cheeks as though it would help bring down the blush. He had never been treated like that, or made to feel any of what Bowser had made him feel. He chewed on his bottom lip, hand moving again to touch the bite mark on his neck.

Why did he feel such pride in it? His mind flashed an image of a similar bite mark on Bowser’s throat, and Luigi felt warm again.

And now…now Bowser wanted him to stay. He could feel that’s what the king had wanted to convey to him, but didn’t really have the ability to put into words what he had only ever shown by kidnapping. And he was sure the castle had figured out he had escaped, so that was a whole nother can of worms they had opened. He knew Mario would be beside himself.

But the thought of staying here with him was oddly intriguing…and it made Luigi smile stupidly to himself.

Bowser wasn’t so bad…not really…their time together had been amicable once they got used to each other. He did enjoy the new relationship they seemed to be developing and Luigi did enjoy his company.

And the king obviously enjoyed his.

Luigi tossed back the last of the juice and stood, letting the sheet fall as he decided to search the room for clothes.

After a quick search, he found his clothes in shreds and tatters on the floor by the bed, and he wondered exactly what he was supposed to wear now. There was a sudden knock at the door, and before he could shout not to come in, the door pushed open, glowing with magic, and the old magikoopa that was always with Bowser, strode in importantly.

Luigi had leapt for the bundled curtain at the end of the four-poster, wrapping it around himself to give himself SOME modesty.

The koopa slowly turned to look in his direction and clicked his tongue in annoyance.

“Hmm…” he hummed, moving to walk towards him. Luigi panicked a bit, holding the curtain up higher. “Lord Bowser wishes to have you join him in his study. I assume, that while he’d like you in your current state…” Luigi squeaked, going red. “I’d think you’d be more comfortable in more covering attire.”

“Y-y-yes! Yes! Please? My clothes are–”

“Yes yes, whatever.” Kamek waved his hand dismissively. He gave his wand a twirl and a wardrobe across the room opened up with a bang, a number of articles of clothing soaring out to land on the side of the bed where Luigi was hiding his nudity. “Get dressed, human. We have paperwork to go over so do not dawdle.”

Luigi waited until the door clicked shut, and hastily grabbed the clothing. A pair of boxers, black slacks, a green t-shirt with the bowser emblem on it, and a pair of orange and green striped socks. He snorted as he put everything on, actually liking that they gave him his favorite color, and enjoying how the slacks clung to his legs. He gave himself one final look in the mirror, turned to look for his discarded boots, and realized sadly that they also met a terrible end by Bowser’s claws.

So he padded across the room in his socks, opened the door that was still unlocked, and stepped out to see Kamek waiting impatiently for him.

He gazed pointedly down at Luigi’s striped socks and raised an eyebrow. “My shoes kinda got shredded…” Luigi muttered.

“Not a problem. There is nothing you need shoes for today so let’s go.” Luigi nodded and followed the koopa through the castle, taking note of all the tapestries and artwork, admiring the architecture, and just racking up countless questions about everything as they walked in silence.

–

The study was less of a study and more of a library with a desk. It also looked like there was enough room between the wall (where a large impressive fireplace sat, crackling green fire), and the large desk and throne-like chair where Bowser was sitting, for a massive table to use for war planning. Luigi glanced up, seeing said war table suspended in the high ceiling, and took note of all the maps and diagrams pinned to the walls like posters in a teenager’s room.

Bowser sat at his throne of a chair, watching Luigi approach with both trepidation and excitement. Luigi smiled at him and gave him a little wave.

Kamek made a little retching noise and pushed past the human to go stand beside Bowser.

“So…paperwork?” Luigi laughed nervously. “The princess never complained about paperwork when ‘she’ was kidnapped…”

Bowser looked sheepish. “Well…” he was suddenly at a loss for words. “Well we figured since I was able to escape, we’d need to…you know…kind of get ahead of the Mushroom Kingdom. We’re not looking for them to try and come find us…me…to take you…” Bowser groaned. WHY was he suddenly so nervous!? He mentally blamed the growing connection–Luigi’s nerves were obviously getting to him.

“What His Destestableness is trying to say is we’re drafting up a peace treaty so they will finally leave us alone.” Luigi was about to say something when the magikoopa cut him off. “Seeing as His Terribleness no longer desires the princess, we are sure the treaty will be acknowledged and agreed too.” He pointed his wand at Luigi. “Especially if their liaison tells them the king is no longer a threat.”

Luigi almost gasped. Peace? Finally? He looked at Bowser who was trying not to seem nervous. And was that true? No longer wanted the princess…? Wait–! “Liaison? Who? Me?”

Kamek rolled his eyes and pointed his wand again, holding him in magic and dragging him quickly closer. “Yes yes yes. Liaison…for now” he grumbled the last part, making Luigi give him a questioning look. “Here,” he shoved one of the rolls of parchment against Luigi’s chest, forcing him to take it. “Read it over, make corrections, SIGN it. I’m sure the princess and your brother are already on their way, and we would like to NOT have our castle destroyed after finally getting it back in order.”

Luigi nodded, looking at Bowser then back at Kamek.

Kamek snorted and shuffled away from the massive desk and towards the door. “If you have any questions, ask your King…I’m sure he’ll be able to attend to any of your queries.” He ignored Bowser’s fuming glare, and scurried out quickly, not wanting to remain while the two, still in the bonding process, were so close to each other.

He made sure to shut the door firmly, grabbing a guard and making sure he knew to not go in, and make sure no one else disturbed the two…ESPECIALLY the koopalings. That’s all they needed…to be traumatized.

Chapter Text

A Mate to Take Care of 3

Luigi sighed the moment Kamek slammed the door, looking up at Bowser a bit nervously. Bowser was almost pointedly NOT looking at him, so Luigi turned his attention to the paper that Kamek had thrust upon him. Bowser was shuffling things on his desk, moving as though everything he was doing was much more important that the little human standing in wait beside him.

After skimming over what amounted to a service contract, Luigi bit his lip and steeled himself to look back up…and demand the kings attention.

“Bowser.” he said flatly, waiting for the large reptile to turn his gaze his way. When it didn’t happen, Luigi felt his own nervousness dissipating. He felt a warmth in his gut that made his body flushed…the heat in his face came in tandem with a rush of anger that the small plumber had never felt before. Before he could stop himself, his fists clenched, crumpling the contract, and he shouted angrily; “FUCKING LOOK AT ME!”

Bowser tensed, head snapping to look down at the fuming human. His glassy blue eyes were now cloudy and dark, glaring up at him with such ferocity, he was amazed they weren’t glowing red like his. And as fast as those clouds rolled in, with a blink, they were gone. Luigi’s eyes were now a bit fearful in their surprise and he raised his hands to cover his mouth–obviously embarrassed by his outburst.

“I–I’m sorry.” he said softly, now not able to look at Bowser. “I don’t know why I–I don’t know why…” Luigi let out a little gasp when he felt Bowser’s massive hands around him, picking him up to set him on the edge of his desk. Luigi wanted to shake–that rush of anger and rage left him cold, and he didn’t like it. He hated being angry in general, but this was almost out of nowhere. He had been so mad…so angry at Bowser.

And Bowser knew why. He had not expected this…He had expected his own nervousness and anxiety was his side of their bond, accepting that the swings of emotions would only be one sided. So why bother telling Luigi?

But this…he could see how unexpected and unwanted that outburst had been. He could smell the confusion rolling of Luigi in waves, masking the little human’s excitement and uncertainty of his new position. Bowser sighed and reached out a hand, using a slaw to gently lift Luigi’s chin and move him to look up at the king.

“We have to talk, don’t we?” Luigi asked, a little shiver coursing through him at the heated stare from Bowser. The king nodded.

“And it’ll be easier if you just ask me what you want to ask me. I’ll answer whatever you want.” Luigi felt a flutter in his chest at that. A vulnerability he had not expected.

Luigi took a deep breath, scooting a little closer so his long legs could rest slightly on Bowser’s armrest, keeping him from swinging his legs and fidgeting too much. “First off…how? How did this happen?”

Bowser chuckled, moving to shuffle papers again and stacking them to push to the edge of the desk where his other papers were. “This happened because a curious little human couldn’t keep his hands to himself.”

Luigi huffed. “I mean your escape!” he groused, brandishing the crumpled contract at him like a disappointed parent would waggle a finger at a child.

“Ah…You cooked for me, and you used spices from my homeland.”

“And?” Luig was confused. Bowser had said that like the answer was something everyone knew.

He chuckled looking at the plumber. “You ever wonder why I was only ever allowed the blandest of foods?”

“Cause you were a prisoner?”

“Because my kind eat the hottest and most powerful spices in almost everything we eat. They build up in our systems, make us immune to fire, to heat from the volcanoes, and enhance those of us with fire powers.” He grinned a bit, even as Luigi’s face sank a bit in realization.

“I kinda gave you a power up then?” Luigi looked completely devastated.

“Kind of…just gave me a little jumpstart. Gave me enough firepower to melt those damned magic’d bars.” Luigi groaned, covering his face in his hands and muttering in Italian. “Ah ah, none of that.” Bowser pulled his arms down and took the contract from his balled fist and placed it on the desk. “You can’t sit there and say it all turned out bad.”

Luigi sighed, but blushed as he nodded. He knew Bowser was right. “O-o-okay then. Next question–”

“I await impatiently.” Bowser teased, smoke blowing out of his nostrils to ruffle Luigi’s hair.

“Why take me?” Luigi waved his hand in front of his face, dissipating the smoke.

Bowser titled his head, smirking. “Why take you at all, or why did I take YOU specifically?”

Luigi blushed. “Both.”

The shrug was quick, but his scarlet eyes never left Luigi. “Maybe I wanted revenge on Mario and knew stealing you away and deflowering his precious, innocent, little brother would give me the best bang for my buck…” Bowser noted the disappointed look in Luigi’s eyes and it gave him an unfamiliar guilty pang. “Maybe it was just a crime of opportunity, hmm?” Bowser reached over and placed a hand on Luigi’s hip, pulling him closer. He was now almost directly in front of Bowser now. “Or maybe…I just like you and wanted to have more time with you.”

Luigi squeaked, shivering again, but not out of fear. Heat bloomed in his body and he couldn’t stop the flush that painted his cheeks and ears. Bowser was looking at him hungrily, but made no other move other than drumming his claws on the desk top next to Luigi.

“Next question?” Bowser was leaning on his other hand, now watching Luigi from half lidded eyes.

It took Luigi a moment to find his voice, shaken to the core at Bowser’s slight admission. “O-o-kay. Answer my question from earlier. Am I a prisoner?”

Bowser frowned. “No. No you’re not.”

Luigi nodded, knowing that’s where the conversation broke down earlier. “Okay…so I can leave.”

Smoke seeped out of the corners of Bowser’s massive jaws, his eyes ringed in gold and flashing scarlet…for just a moment. He closed his eyes briefly and when he opened them again, they were normal. Luigi said nothing, but noticed a spike of angry annoyance that accompanied that brief flash…and just with the last, it was gone in a blink. “Yes. Yes you can leave.”

Luigi looked surprised, but did not move. “Is that a lie?”

“I don’t LIE!” Bowser fumed. “I said what I said. Leave if you want to…!” Did his voice crack? Did Luigi sense the bone deep sadness that was left in him after that admission?

Luigi nodded, but still remained seated on the desk. They both eyed each other. “But…” Luigi prompted, raising a hand as if to signal for Bowser to continue…and Bowser was amazed the human had caught that he had wanted to even add more to that comment.

“B-but…BUT…” Bowser grumbled, eyes looking off to the side as he muttered out; “But I’d hope you’d want to stay.”

Luigi nodded, almost as if that was what he had expected. “Okie dokie. Just wanted to hear you say it.”

Bowser gaped at him, eyes glowing. “Wh-what?”

“I just wanted you to admit it.” Luigi said, still a little shaky, but muscling through his anxiety. “Wanted to hear you say you liiiiike meeee.” he teased softly, cheeks going pinker.

Bowser couldn’t stop the tickled grin that spread across his maw. He was about to say something back, but started laughing instead. Luigi’s own laughter joined him, and he felt weirdly content for the first time in a long long time.

When they finally caught their breath, wiping tears from their eyes, and allowed themselves to return to their current situation, both could only stare at each other for what felt like a little too long. Luigi looked away first, clearing his throat, and hoping Bowser didn’t see the pink flush getting darker.

“O-okay, next question.” He was still looking away from the koopa, his hands resting on his knees to keep himself from fidgeting with his fingers. Bowser tilted his head, waiting for him to continue. After a long moment where Luigi obviously struggled a little bit with what he wanted say, he finally took a breath and turned his full attention to the king. “What exactly do you want with me?”

Bowser hummed, able to feel the roiling anxiousness from Luigi in his own stomach. He wondered if Luigi could feel his? He hummed in thought, tapping his chin with his claw as he leaned back a bit in his chair. He regarded Luigi with half lidded eyes, raking them over his entire form. It made his skin prickle and he knew Luigi was getting flustered.

He had a sudden idea…wanting to test their growing connection and whether it was one way or not. Thinking another long moment, Bowser purposefully began to imagine Mario coming to take Luigi away. How would he feel? What would he do? He concentrated hard on it, trying to make sure his outer expression was still absently thoughtful. The sudden flash of anger in seeing HIS Luigi taken away from him was bright and hot. It boiled his blood and made his insides squirm uncomfortably. But he was doing this as an experiment, so he was able to reign it in, still keeping his eyes locked on Luigi in a fairly neutral (albeit slightly hungry) expression. The rage and anger and desperation he felt was real though…what he was looking for was to see if…yes…there it was…

Luigi’s fists clenched over his knees and the flush appeared high on his cheeks. Bowser watched in fascination as the lanky plumber’s jaw clenched and unclenched, the muscle tensing. The crystalline blue eyes grew gray and cloudy once again, and Bowser, seeing what he wanted to see, let go of the anger he held. It dissipated like a cloud of smoke, and he watched as Luigi relaxed. The confusion on the little plumber's face said it all.

He felt it, but he didn’t know why or even where it was from. Bowser sighed and reached out to take a hold of Luigi’s chin, tilting his head up again to lock eyes with him. “Do you want the truth or do you want me to make something up?” Bowser felt his stomach flutter nervously as he waited. If he didn’t want the truth, he’d say something about needing a release and knowing Luigi would be amenable. Having to tell him about Bowser’s mating attempt was something truly nerve racking…but he hoped…sincerely hoped…

“The truth. Of course!” Luigi gave him an incredulous look. He reached his hands up to gently hold onto Bowser’s thick wrist.

“You felt it right?” Bowser grumbled softly.

“Felt…felt what?”

“That anger…I saw it on your face. And earlier, when you yelled…”

Luigi nearly choked, flushing in embarrassment as he tried to look away. Bowser tightened his hold, forcing Luigi to keep looking at him. “H-how did you know?” he squeaked out.

“Because it was from me.”

Luigi blinked in confusion. “What are you saying?”

“I was not aware that you’d feel the bond. I shouldn’t have done it, but I’m nothing if not a selfish creature of passion…and recklessness…” he grumbled the last under his breath. “I bit you. I knotted you. And it would have been alright, but you bit me.” Bowser let Luigi’s chin go, giving him a sheepish, almost pleading look. “I shouldn’t have tempted the fates…”

“A bond?” Luigi’s hand moved to run his fingers over the mottled bruise on his neck. He gasped, leaning forward, ignoring Bowser’s almost imperceptible flinch (had he really thought Luigi would strike him!?), and touched the small bite mark on Bowser’s throat. “A bond! Like…a mate!?”

Bowser swallowed and Luigi felt the movement under his fingertips. The nervousness was back, and Luigi snapped his gaze to pin Bowser in place. “Yes. Like a mate.”

The words hung between them, Luigi trying to wrap his human mind around the idea of a mate…like some birds mated for life? Like wolves mated?! KNOTTED!? Luigi flushed brightly as that word tumbled through his mind. He had bitten Luigi and Luigi reciprocated…had that been it? He mentally groaned, realizing that he should have probably had more of a conversation with Bowser before letting the king fuck him senseless. Hell, he didn’t even ask questions about the mushroom!! He was in this bad, for sure.

Bowser was getting a little antsy…Luigi had a far off look in his eyes, and he was getting worried he was thinking too much about the whole situation. He really had thought the human was going to be angry, but he felt nothing but an eerie calm between them. He was about to say something to break the uncomfortable silence when Luigi spoke.

“Does this mean we’re married?” He blurted out, hands now moving to grab Bowser’s thick jaws and locking eyes with him. “Are we married, Bowser?!”

Bowser couldn’t help but laugh, cutting it off when he saw the slight worry and seriousness in his little human’s eyes. “No…we’re not married…”

“Can we be!?”

Bowser and Luigi simply stared at each other. He had not expected that…at all. He had expected Luigi not reciprocating any of his feelings…he had expected having to live with this bond and exist without his other half.

He had not expected THAT.

“You…what?”

“If I’m bonded or mated or whatever to you, does that mean we can get married?” Bowser was still expressionless, staring at him and waiting for the punchline.

“Do you want to get married? I didn’t think…”

Luigi laughed, eyes glittering. Bowser could feel the warmth building in his chest and he couldn’t keep himself from taking a steadying breath. “I don’t know!” Luigi said with a laugh, still smiling. “But it feels like the RIGHT thing to do! Like…it feels right!” He laughed again, his smile reaching up to his bright eyes.

“I…I mean…” Bowser laughed at the absurdity of it all. “Greenie, are you serious? Are you really being serious or are you just fucking with me right now?”

Luigi scooted so he was now directly in front of Bowser, planting his feet on the seat, a foot on either side of the king’s wide lap. “Dead serious.” Luigi said, pulling Bowser forward with the hands on his jaws, and kissed his snout sweetly. “And, OH! Oh listen to this!” Luigi was almost vibrating as he wriggled excitedly. “I didn’t get a chance to tell you on account of the bath and cookie incident…and…this…” he motioned between them. Bowser was listening intently, his eyes never leaving Luigi’s smiling face–too dumbstruck in his luck to risk looking away. “Mario asked Peach to marry HIM! They’re planning the date and everything.”

“O-oh…” bowser had thought having heard information like that, he’d feel some kind of disappointment or sadness…there was nothing…just the warm contentedness that seemed to grow with every moment he was near Luigi.

“So…SOooo…When they get married, that’ll make Peach a Queen and then Mario like…a King Consort thing, right? That’s what they said…” Bowser was nodding along, amused but confused as to where this was going. “So that makes me kinda like a prince! Or it will, right?! A prince-thing of the Mushroom Kingdom…”

Bowser’s eyes widened, finally connecting the dots Luigi was stringing along. Luigi gave him a smug little look when he noticed that Bowser had picked up what he had been putting down. “A prince…of the Mushroom Kingdom…”

“RIGHT! So…no peace treaty needed! We’d mash the kingdoms together,” He clapped his hands together excitedly. “With marriage!” Bowser let out a deep laugh, grabbing Luigi and yanking him down into his lap, hugging him close.

He was right. With THAT kind of union, they’d be able to unite the kingdoms without the endless runarounds of peace negotiations. Now they could still have treaties to strengthen the union, but a bond between kingdoms would be the strongest by far. They’d have no reason to come after Bowser anymore, even after he had escaped. He’d be able to negotiate his penance without risking the Mushroom Kingdom or a neighboring kingdom imprisoning him before things got done.

Luigi kissed his nose again, hands moving up to run gently over the king’s scaled cheeks.

“You’re really okay with this?” breathed Bowser, ducking his head and hiding his snout in Luigi’s shoulder again. There was this terrible piece of him that had been terrified of how he’d react, and that was NEVER something Bowser worried about. This anxiety and fear was new…he didn’t like it, but it was nice to feel that connection with someone.

“If I wasn’t, I’d just leave…but that really feels like the wrong thing to do.”

Bowser’s arms tightened around the little human, a possessiveness welling up in him that he hadn’t felt since Junior had hatched. Having Luigi so close, smelling all the emotions rolling off him in waves, feeling his warmth against his plastron, it was all making every nerve end sing with excitement. He snuffled against Luigi’s neck, giving the bite mark a playful lick and grinning when he felt Luigi shiver against him.

“So, going back to your little prince comment,” His claws gently trailed down until he was almost completely palming Luigi’s ass. “Do you want to wait until your brother marries his princess to make you a little prince…?” He let out a low rumbling growl, opening his maw and letting his teeth scrape over the bite mark there. His tongue lathed over the bruises teasingly. “Or you wanna be the one that makes YOUR brother a tiny prince by becoming your King’s Consort first?”

Luigi shuddered, hands grabbing at Bowser’s horns as if to keep him grounded. Every touch from the koopa was making him weak in the knees. Hearing his question, Luigi let out a breathy laugh. “Th-that’d really chafe Mario’s ass.” Bowser growled, tightening his hold, claws digging into the fabric of his clothing and threatening to shred it.

“Mario’s ass is NOT what I want to be picturing right now.” he rumbled, maw finally clamping down on Luigi’s neck and shoulder before letting out another gravely trill.

Luigi gasped, arching into his grasp. “S-sorry! No more talk of Mario’s ass…”

Bowser nearly roared against his throat, picking him up and depositing him onto the desk where he loomed over him. Bowser stared down at the flushed human, amazed he wasn’t flinching and shaking in terror, but looking up at him with such adoration that Bowser was momentarily frozen in place.

But Luigi was stretched beneath him, having been slid onto the desk, his shirt rucked up to show a pale expanse of skin and a dark trail of hair leading into the slacks he was wearing. Bowser trilled, leaning himself over to completely cover his human. Luigi’s breathing had picked up and his hands were grabbing at whatever he could find, running up Bowser’s arms when the massive koopa caged him, claws nearly gouging into the dark wood on either side of his head.

Bowser wasted no time, dipping down to continue running his tongue across Luigi’s collar and up his arched neck before capturing his lips in a searing kiss. Luigi whined against his lips, hands moving up to run over his snout and up to his wild mane. Bowser pushed him up a bit further on the desk, making sure his ass was on the wood top before raking his claws down his body and tugging at clothing.

Luigi pulled away, gasping again. “D-don’t rip…” Bowser snorted, gently inserting a claw under the waist of the slacks and tugging up, unbuttoning it instead. Luigi let out another one of those breathless laughs that had Bowser kissing him again. The large koopa king was grinding his hips between Luigi’s, trapping him perfectly against the desk with his body. Luigi whined when Bowser broke the kiss again, fanged maw going to move back down before the claws pushed up the green shirt, exposing Luigi to both the cool air and Bowser’s hot breath.

“C-ca-cazzo,” moaned Luigi, arching his back as sharp claws trailed down his chest and sides. He almost wanted to laugh, usually very ticklish, but the sharp claws had him shivering with anticipation instead. They left little scratches, small welted lines down his expanse of skin, and with every touch and breath from the king, he broke out in the most wonderful goosebumps.

Bowser’s tongue lapped at the cool skin beneath him, loving how each swipe of his hot tongue brought new and wonderful noises to his human’s lips. Dragging tooth and tongue down to his hip, Bowser tugged at the dark slacks, pulling back as he hooked both boxers and slacks with his claws and pulled down.

He trilled happily as he pulled the offending clothing down, watching as Luigi’s fully erect member bounced up, happy to be freed from the cotton confines. Luigi was a melted pile beneath Bowser, squirming and panting as he felt Bowser blow out a hot breath over his weeping prick.

“B-Bowser…” pleaded Luigi, but the king simply ignored him. Instead he leaned in, hot tongue dragging over the base of Luigi’s member, wide tongue almost hugging both sides as he moved the long muscle all the way to the tip. Luigi let out a keening whine, hips bucking up. Bowser chuckled, claws grabbing his hips and holding him down as he continued to drag his tongue lazily over every inch of Luigi.

Bowser looked up to Luigi, pleased to see the human coming undone beneath his own actions. Finally taking his full prink into his maw, Bowser trills, rolling his tongue against Luigi’s cock and making the Italian cry out in pleasure. He continued this, his tongue, almost prehensile, wrapping and slithering around his member before hollowing his cheeks a bit and giving Luigi a nice long draw. Bowser’s snout was buried in Luigi’s happy trail, snuffling appreciatively and loving the scent that the human had always had, allowing his cock to reach almost all the way to the back of Bowser’s throat…not quite, but enough to give Bowser a bit of a thrill without choking or gagging.

The thought of Luigi choking on his massive cock made him rumble out a deep moan. Plenty of time for that…now is about his human. Bowser pulled back before diving back down, sucking hard enough to make Luigi cry out, desperately wanting to thrust up into the almost uncomfortably hot mouth of his king. Instead he remained pinned, his hand grabbing at Bowser’s hair and horns, whining pitifully as Bowser continued his assault.

He wasn’t going to last much longer, and he tried to warn Bowser. He tugged at his horns, stuttering out broken sentences, but Bowser knew what he was trying to say, and actively ignored him. He wanted this and wasn’t going to let the little human take it from him…not that he would.

The king of the koopas gave one more long drag, his tongue wrapping tightly around Luigi’s cock as though it had a life of its own. He bellowed, opening his maw a bit to press his fangs over Luigi’s lower waist and the top of his thighs. This, and the look Bowser was giving him, made Luigi come. His head snapped back, hitting the desk almost painfully as he orgasmed, hands scrabbling to grab whatever he could of Bowser as the other continued using that damned tongue to stroke him through his completion.

Luigi whined, his overstimulated cock still being licked by Bowser’s hot tongue–the dragon king making sure he captured every drop before he pulled off his human, swallowing and licking his teeth and lips almost obscenely as he stood up to tower over Luigi again.

Luigi was trying to catch his breath, spread out in front of Bowser like a delectable snack. Bowser, grinned and began to help his little human up, helping tuck him into his boxers and slacks, and straightening his shirt over his trembling figure. He leaned in, loving how breathless and rumpled his little human was, and gave him a kiss that would have set Luigi back to full attention had he not just had his soul sucked from his body.

“Come on, Greenie. We have a ton of paperwork we gotta get through. I really don’t want your brother coming to rescue you and interrupting us. Do you?”

Luigi ran his hands through his mussed hair, finally catching his breath and hastily buttoning his pants. “N-not even a little bit.” he laughed, accepting Bowser’s help off the tall desk.

“Good. Let’s get lunch and discuss things while we eat. Plus…I kind of need to introduce you to my kids.”

“Lunch sounds gre–KIDS!?”

Chapter Text

Luigi trotted after Bowser as the massive koopa led them from the study and out into the hall. “Are you serious? You have kids!?”

Bowser chuckled, flushing a bit as Luigi pinned him with his wide eyes. “Yeah…eight.” He scratched the back of his neck, looking a bit sheepish as he realized he had dropped a bomb-ombshell right onto Luigi’s head. Luigi was obviously struck dumb by the revelation, and continued to walk alongside him in contemplative silence.

“Does Princess Peach know you have kids?” Luigi finally asked, looking up at Bowser as they took another series of turns into an unfamiliar hallway. 

“What? No. I had no reason to tell her…”

“You were trying to marry her!”

“Meh.” He waved his hand dismissively. “I’d have told her after the wedding. It’s not that big a deal.”

Luigi laughed. “Bowser…eight kids? Not a big deal?”

“Well only one is mine…the rest I kind of adopted.”

Luigi dragged his hand down his face, trying to remain incredulous to the koopa’s nonchalance, but felt a warmth spreading in his chest at finding out Bowser had adopted seven orphan children. He did adopt them right? “Were they orphans? Er…” Luigi gave him a wary side eye. “Did YOU make them orphans?”

Bowser’s head whipped around towards Luigi and he snorted a plume of dark smoke, eyes glowing.

Luigi raised his hands defensively. “Okay okay, got it. I didn’t mean anything by it, just curious.”

“You really got a brutal picture of me don’t you?”

“You pulled my mustache, threw me in a cage, and tried to flambé me…at least five times. It’s a pretty clear picture.”

Bowser frowned, trying to not get irritated, but failing.

Luigi could feel the mix of guilt and anger that Bowser was currently feeling, and simply reached out to take the king’s claw in his hands. “But pictures can always be retaken,  yeah? Nothing is set in stone.” 

Bowser felt that warmth in his chest again and looked down at Luigi with a surprised look. They had stopped, Bowser finally having led them to the dining wing. There were soldier dining halls, staff halls, and one for all his big parties and gatherings. The one they were going to was the royal hall for the royal family and guests. He gave Luigi a little nod, smiling slightly, and almost overwhelmed as the feeling of something warm and kind swept through him.

“Th-thank you.” He said quietly, and Luigi smiled that bright smile again. “I am sorry for all that…I should have said that before now…even before everything at the castle…”

Luigi waved his hand dismissively this time. “Meh.” he parroted, laughing slightly at Bowser's shocked expression. “I know you’re sorry. I don’t hold grudges though, so it’s all good.”

Was it though? He had tried to kill the little human…how many nightmares had he had? How many times had he brought up how fucked up that entire thing had been. He couldn’t help looking at Luigi a bit disbelievingly, but said nothing to the contrary. He’d bring it up later.

He gave a breathy sigh and nodded. “Alright, let’s rip this bandage off fast. They may rush you…fair warning.”

Luigi had only a moment to look fearfully surprised before the door opened, and Luigi was greeted with a large round table overflowing with chattering little koopas.

The smallest one, standing on the table and flinging a carrot or some vegetable at one of his siblings, was the first to notice them.

“PAPA’S BACK!!”

And Luigi had the good presence of mind to step back and slightly behind the massive Koopa king as the koopalings swarmed him. They acted like they had not seen their “papa” in weeks…

And Luigi’s  heart sank when he realized it had actually been months .

The smallest–looking like a tiny Bowser himself–was latched onto Bowser’s neck, soft chirping and clicks the only thing he could get out as his breath hitched and he tried not to cry. From what Luigi could see of the others as they climbed and hugged and pulled at their dad, a few of them sported their own wet eyes and tear tracks.

And to think…no one, NO ONE, knew he had these children. They had their father taken from them and only knew that he was gone. Luigi was almost surprised that Bowser had done anything other than rush to them before doing anything else.

But the entire ordeal was a bit heavy…especially when dealing with Luigi being in the picture now.

“Okay okay! Calm down!” Bowser laughed, tossing a few up in turn before putting them back on the floor. Luigi swore he heard Bowser’s voice hitch…the sound of  his words tight and thick. “I have someone to introduce you to…so you lot better behave.”

Eyes had already turned to peer around their hulking father. Colored eyes that matched colored shells narrowed in his direction and Luigi was VERY sure that the koopalings knew who he was.

“Why is he here?” That small one snapped, his stuggy clawed fingers grabbing so  hard at Bowser’s horns from where he sat on his dad’s shoulders, that it was making Bowser’s head jerk up. He growled and the little one loosened his grip.

“Yeah…isn’t he one of the ones that took you, daddy?” The small girl koopaling, holding tight to his leg and peering from around his shell at Luigi, was glowering better than anything he’d ever seen from any princesses he’d met.

They were all glowering, and Luigi held up his hands, trying to show them he meant no harm.

Bowser sighed. “This is Luigi. Lu–ee–gee.” He repeated the name, and Luigi saw a little smirk on his lips as a couple echoed it back. “He did take me…but to be fair, I may have deserved it a little.”

One of the kids scoffed, crossing his arms. “Fat chance. There’s no way this thing took down the biggest, baddest koopa in the land…”

“He had a Super Star and a mini mushroom.”

The collective “Aaaaaahhh,” the kids said together, little heads nodding, made Luigi almost laugh. They simply accepted it…their dad told them what happened, made no attempt to lie, and the kids…understood.

“I still don’t like him.” Groused a thick koopa as he crossed his arms over his plastron. He was almost up to Bowser’s shoulder–very  much Luigi’s height–but at least thrice his width and muscle.

“You ain’t got to.” Bowser said kindly, patting his head and he relaxed. “But you do have to respect him and leave him alone. He’s going to be with us for a while.”

“EWW!”
“WHAT!?”
“No way!”
“Does he play games?”
“Can he cook?”
“Where’s Peach?”
“Does he  have to stay?”
“Dad he’s funny lookin’!”
“Papa can I play with him?”

It was all of a sudden jumble of noises and voices and Luigi took a step back, worried Bowser was going to explode.

Instead…Luigi watched as Bowser simply waited. Where did this patience come from? This kindness? Sure Bowser had changed over the months he’d been caring for him, and it was obvious there were even  more changes between them as this bond they had took hold deeper and deeper down…but this was NOT the Koopa he met on the floor of his throne room.

This was not the koopa that he had once feared.

Bowser waited until their voices died down, lips pressed tight and eyes lidded and bored. He clicked his tongue and reached up to pry the littlest off his shoulders. “If he wants to play, then that’s fine. Do not say Ew, he is here as my guest and you will respect that.” They shuffled foot to foot, not looking at Luigi, a little chastised.

“He does not look funny, he’s a human. That’s just how they look.” Luigi caught the glint in his eye as he looked down at him, and the plumber could tell he was trying not to laugh. Luigi huffed. “He is going to be a diplomat between me and Mushroom Kingdom. Your old dad is tired of fighting, and I missed you all so much–I’d rather not be gone again…so he’s gonna to help me with that.”

Luigi saw he wasn’t telling them everything , but what he did seemed to ease them. The glowers were simply sideways looks and searching glances.

“Now come’ere and lemme introduce you.” The group shuffled together and Bowser stood to the side, looking down so damn proudly at the little Troup that Luigi felt himself melting. Oh Madonne, he was precious…

He pointed to each in turn, telling Luigi their name and having them voice a small “Hello” before moving to the next one. When they were all done, he shooed them back to the table and reached over to snag Luigi’s hand. “Let’s get something to eat before they destroy it all. You shouldn’t have any problems with them, but don’t put your hand near Iggy’s mouth, he’s at his biting stage…And it goes without saying Greenie…” The look Bowser gave him made Luigi’s stomach churn hotly. It was the look he imagined he’d see on a mama bear if one crossed paths with her and got between her cubs and her.

“If you hurt them…bond or not…I’ll kill you.”

Luigi did not, even a little, blame him or feel called out. He honestly hoped to one day (since he seemed to be staying for the long haul here) to feel the same way about the little ankle biters. “I’d sooner throw myself in lava before I let anything happen to them.” He said, squeezing the massive hand of his… HIS! ...Koopa king.

Bowser seemed to like this answer and smiled. He felt the honesty from the other and it made his heart thud happily behind his plastron. He smiled and felt his stupid heart stutter and speed up when Luigi returned the smile with his own, reaching up and twirling that stupid ( fantastic…AMAZING ) mustache.

“Good to hear Greenie. Let’s get us some grub then.”
