Somewhere in the Dark Lands was Bowser, King of the Koopas, depressed and defeated yet again by the Mario Brothers after yet another plan had failed. No matter what he did, somehow, someway... those damned plumbers manage to win! What the hell was he doing wrong?!
He even tried to make a friggin' Galaxy to win her over! And that blew up in his face! Figuratively and literally. Maybe he just didn't deserve to be happy after all. Maybe the Gods or some other higher being was having a laugh right now watching him fail again and again. Bowser gave a deep sigh and soon retired to his chambers.
His son, Bowser Junior watched as his father trudged back into his room and heard the doors slam shut. He felt bad. He hated seeing his father so down and worn out. The young Prince loved his father so much, even to the point that it seems taboo for many people.
Behind closed doors, Bowser was honestly trying his damndest and to make Junior happy. If only there was a way he could make his Papa happy while also keeping his little secret hidden. That's when he had an idea. Of course! Why didn't he think of this earlier?!
Junior rushes to his room and looked around for something, his room was filled with all sorts of toys and many pictures he's drawn or painted.
"Where is it, where is it...?! A-ha!" He finally found what he was looking for and it was a magic wand. He conjures some magic and created an outfit of a Nabbit that was just his size. "Perfect! I can help cheer up Papa by disguising myself as this thief!"
He soon put the costume on, it fit like a glove. Although, it was rather skin tight, leaving him exposed in certain areas. He looked at himself in the mirror, turning around and seeing his ball sack and plump ass.
"Mmmh... rather tight... But it'll work!" Junior says and then sighs sadly. "Oh, Papa... I'll make you happy again! I'll even be your... p-p-princess...~" He blushes and realizes he shouldn't have these thoughts about his own father, but how could he not?
His secret is that he really loves his father to the point of becoming his lover. He knows it's wrong, taboo and downright weird. But he couldn't help it. His father did so much and yet, he was shat on in life constantly. Besides, he can just imagine his confession going all kinds of wrong and maybe even worse...
He didn't want that to happen. Right. It was time for Operation: Cheer up King Dad!
Junior makes his way to his father's room and quietly opened the door, he looked around and saw Bowser sitting on the bed, looking as defeated as ever. His heart ached seeing him like this.
"Alrighty Junior... you got this! Right now, you're not the Prince of the Dark Lands, but Nabbit. Here I go...!" His says quietly, his voice muffled by the head he has on. He starts to make his move as he enters the room.
Bowser heard the door open. Who dares enter his chamber?! Looking up, he saw 'Nabbit' and sighed. "Now's not the time, Nabbit."
Junior, as Nabbit, spoke up, but due to the disguise, Bowser couldn't exactly make out what he said. Something about being sorry for him and wanting to cheer him up, or something along those lines…
"Is that so, huh?" Bowser began. "Look, it's just… It's getting harder and harder to kidnap Peach every time."
Junior sat next to Bowser as he listened to his problems. "Don't tell Junior this, but… There's a reason why I kidnap her and not, say, Daisy."
Junior cocked his head in confusion. What did he mean by that? And why didn't he want to tell his own son about this? Whatever it was.
Bowser sighed again. "Junior never had a real mother; he just showed up one day and I took him under my wing. He seems to like calling Peach his 'Mama', heh… That's why I keep trying to take her. Not for any cake, or anything like that. I just want him to be happy."
Junior was so stunned by this, he almost cried. But he needed Operation: Cheer Up King Dad to continue; he didn't want to blow his cover, yet.
Still though, Bowser kept this up… For him? And people said he was the bad guy! Granted, the Koopa Army were the bad guys, but that's beside the point! It was time to put his plan into action.
That was just another reason why he loved him so much. Junior climbed onto Bowser's lap and grabs his father's claws into his own gloved ones.
"I could... uhm... make you feel better, Lord Bowser." Junior said, again, his voice muffled by the head he's wearing. It felt weird calling his dad by name and title. But he has to play along.
Bowser looked confused and cocked and eyebrow at 'Nabbit'.
"Make me feel better how? With me faling again and again, I think Junior thinks I'm just washed up." Bowser said sadly.
That tore Junior's heart apart. He had never seen him this bad before. Bowser definitely needed this ASAP.
"I could... pretend to be... who you care for? N-not that I don't care about you at all! It's just... I'm so bad at this." Junior silently curses at himself, why did he now have to be terrible in this moment?! "As your loyal minion... I want to make you happy, Lord Bowser. What can I do? Tell me."
Bowser was surprised that 'Nabbit' would go through all this trouble, even hearing his little sob story about his true reasons for doing what he does. But he thought about it. He never did have time to make himself happy, did he?
Junior looked at Bowser as he seemed to be deep in thought. Waiting patiently for him to explain how he can make him happy.
Eventually, Bowser got an idea: He didn't get any me-time for quite a long while, and he'd been rather pent up lately. And seeing as how cute 'Nabbit' looked… Wait, did he always have such a curvy figure? Ah well, perhaps his memory was slightly foggy.
"Would you do anything?" Asked Bowser.
"Anything, Lord Bowser." Junior replied.
"There is one thing…" Said Bowser. As he revealed his flaccid cock. "Go on, do whatever you'd like~"
Junior was utterly shocked at this. Was he seriously gonna do… THAT to his own father?! Then again, he did just say he'd do anything.
Junior cupped Bowser's massive balls and watched his dick slowly became erect. The bigger it got, the more turned on Junior, became. It was bigger than he-Wait, what were these thoughts doing?!
Junior had no time to think as he heard Bowser sigh. Not in sadness like before, but in pleasure. "That's it, keep going~"
Junior continued, rubbing and massaging Bowser's balls, eying the beast of a cock before him. Holy shit... could he even take that? He bet it feels good...~ Those random thoughts popped up again. Was he really this infatuated with his own father to go all the way?
Inside Junior's costume, he felt a tightness around his crotch and a bulge slowly formed. He was getting turned on. He whimpers a bit, feeling the strain around his suit.
'O-oh God... so tight...! I'm actually pleasing Papa like this...! But... if it makes him happy... that's good enough.' Junior thought as he blushes. He wishes he could suck or lick it, but he didn't wanna reveal himself.
"Mmmhhh... that's it, Nabbit... such a good minion. Have you done this before?" Bowser asked, and 'Nabbit' turned his head, acting shy. "Well, it doesn't matter. It already feels good~"
"Anything for you, Lord Bowser~" Junior replied.
Once Bowser's cock was fully erect, Junior moved his hands from his dad's balls to his dick and slowly began stroking it. This caused Bowser to moan. "Aah! Damn, this is good~"
Junior blushed under his costume. He couldn't believe he was really doing such a lewd act to his own father! But if this is want to be done, so be it!
As Junior sped up, Bowser's moans increased. Damn, 'Nabbit' was doing so good! Why hadn't he did this before? "Keep going, Nabbit! Please your king~"
Junior continued to jerk off his dad's cock. Many thoughts were soaring through his mind. 'This is… Good, actually!' He thought. 'As long as he doesn't ask me to suck him off, I'll make him happy in no time!'
Some precum was leaking from Bowser's cock, as the Koopa King groans some more, the feeling of 'Nabbit's' hands stroking his erection felt so good~
They went at this for a while, Bowser moaning and breathing heavily, feeling pleasure coursing through his throbbing length as Junior continued rubbing and pleasing his father.
"Nnnghhh...! Fuck...! I'm gonna cum...!" The Koopa King growled out, Junior sped up his movements even more after hearing that. Soon enough, Bowser gave a loud roar and blew his load, staining 'Nabbit's' head and the floor.
Junior was just amazed at the amount his father has. His eyes wide and blushing at the sight.
'H-holy shit...! Papa wasn't kidding when he said he was pent up! Hopefully this would be enough.' He thought himself as Bowser sighs, calming himself after his orgasm.
"Hah… Hah… So good~" Bowser panted before looking at the cum-covered 'Nabbit'. If he was honest, looked he was pretty damn cute covered in his own seed.
He also noticed that he was still hard. This gained a good idea for Bowser, but bad news for Junior. "Hm, guess that wasn't enough. Wanna suck me off?"
Junior's eyes went wide underneath his costume. Shit! If he did that, he'd blow his cover and who knows what'll happen after that? Would he get grounded? Spanked? A combination? Something worse?!
Bowser frowned as he saw 'Nabbit' shake his head no. "You said anything, didn't you?" He asked. "Now put that mouth of yours to good use~"
"N-No!" 'Nabbit' cried.
At this, Bowser got furious. "I said do it! Your king commands you!" He said before reaching down and taking off 'Nabbit's' mask without warning.
'Oh fuck…' Junior thought as his true identity was revealed.
"Wha-? J-Junior??" Bowser gasped. Was he-? Did he-? With his own-?
That's when Junior ultimately decided to come clean. "H-Hey, dad." He said sheepishly. "I… I saw you upset about what happened and… I thought that I'd cheer you up as Nabbit."
Junior squeezed his eyes tightly. Bracing himself for Bowser's anger. Then, after a brief moment of awkward silence, he heard him sigh. "Junior, I… I'm not mad at you."
…Wait, what?
Junior opened his eyes and looked genuinely confused.
"W-wha...? Y-you're not? But I... I mean..." The Koopa prince tried to explain, but found out he couldn't.
"You were doing something to make me feel better. But... why the disguise? Why dress as... Nabbit?" Bowser says and gestures to his son, still wearing the costume.
The young Koopa lowers his gaze, almost like he was embarrassed and ashamed.
"... I've had... feelings. I love you, Papa." He admits, to which Bowser was confused.
"I love you too, Son-" But he was stopped as Junior shook his head and his lower lips trembles.
"No! I-I mean... Love-love... you know? Like... with Mama Peach?" He says, trying very, very hard not to cry.
Oh. Bowser was surprised at that, but given everything that's happened in their lives. He honestly should've guessed. But to think... his own son, having feelings for him THAT much?
"S-so I disguised myself... s-so you wouldn't know it was me! A-and... think I'm some... p-pervert or freak..." He made fists and started to shake, trying and failing not to cry. "Please don't hate... I wanted... I..."
Part of him loved pleasing his father like that, but the morality kicked in and he felt so guilty. He just used his father's sadness for his own selfishness. At least, that's what he thinks.
Finally, the dam burst and Junior began crying. "PLEASE, PLEASE FORGIVE ME, DAD! I promise I'll never do it again, I promise to never tell anyone about it, just please don't ground me!"
Bowser frowned at this. He hated seeing Junior in so much misery just as much as Junior hated seeing him defeated by Mario. Bowser placed a hand on Junior's shoulder. Junior looked up at him just in time for Bowser to pull him in for a hug.
"There there, Junior." Bowser comforted. "Like I said, I'm not mad; just surprised."
Junior sniffled. "R-Really?" He asked through the tears.
"Really, son. I love you, too." Bowser let go and looked at Junior again. "Now then, where we’re we?"
"B-But, isn't this wrong?" Junior asked. Shocked that Bowser still wanted him to suck his cock after what just happened.
"Heheh! There's nothing wrong with showing love for your old man~" Bowser laughed.
Well, if his dad said it was okay, then it was okay! After Bowser sat back down on the bed, Junior gave the tip of his penis a lick. It was small, but enough to make Bowser moan.
"Mmf! That's it, Junior~ Suck your dad's cock~" He groaned.
Junior continued licking, even giving it a couple of kisses here and there. He couldn't hide the blush on his cheeks as he heard his father's comments.
'If Papa says this is okay... then... I'm not worried anymore.' He thought and opens his mouth, taking the head of Bowser's cock inside. Of course, it was too big and he could only fit some it inside.
Bowser groans as he watches Junior trying his best to suck him off, slowly bobbing his head as he was getting used to it.

"Oooohh... that's it, Junior... Worship's your Papa's cock...~" The Koopa King moans out, he even heard his son making cute little moans and slurping noises.
"Mmh... s-sho big...~" His voice muffled by the erection inside, the tightness around his bulge was making him squirm. There was no need for his disguise anymore.
Junior tore the crotch off of his costume. Allowing his cock and balls to air out. As Junior sucked off Bowser, he couldn't help himself and began jerking off. Bowser saw this and chucked.
"Heh! Can't help yourself, huh? I don't blame you~" Bowser moaned before gritting his teeth. "G-Getting close, son! Get ready for it!"
'I'm ready for it, Papa!' Junior thought lustfully. 'Give me all your cum~'
Bowser thrusted ever so slightly as to not hurt Junior, and then he came. Roaring as he did so. Junior's eyes widened at the sheer amount of cum that flooded his insides. His stomach even bulging as a result.
Once it was all over, Bowser pulled away and stained Junior's face with his cum. "Hah… You like that, Junior?" He asked.
"Y-Yes, Papa~ Your cum is so yummy!" Junior replied. Really getting into it now!
Bowser couldn't help but chuckle at how raunchy Junior was getting. And he also couldn't help but notice Junior's erection. And the fact that he hadn't cum yet.
This gave the Koopa King another idea. "Say, you wanna take more of my cock, son?" He asked.
Junior's eyes lit up. "I do! Oh yes, I do, Papa!"
Bowser grabbed Junior's costume and tore it off, revealing his son's plump and fat ass. He lifted the smaller Koopa easily and hovered him over his cock. Junior stares down, is heart racing as he couldn't contain his excitement. Size be damned, he wanted it!~
"Are you ready for Daddy's cock inside you, Son?~" He whispered to him sensually, making Junior shudder and nod quickly.
"Y-yes, Papa...! I'm ready! Please stick it inside me! Anything to make you happy~" Junior replied, his voice shaking with need, his own cock twitching.
He couldn't wait to have this monster of a cock inside him~ Without wasting time, Bowser lowered his son until it slid inside of his tight asshole. Both males groan in pleasure as Junior winces.
"Ghngh...! P-Pa... Papa...~ S-so... f-fuckin'... big...!~" It sounded like he was enjoying it, Bowser started thrusting inside as Junior was along for the ride.
"Gah! Mmgh! So fuckin' good~" Bowser moaned as he thrusted deep into his slutty son's asshole. Listening to his cute moans of pleasure.
Junior's ass jiggled with every thrust. He needs it! He needed his Papa's fat cock in his ass! Feeling like he'd die without it. Junior's tongue flopped out as he began giggling. Bowser chuckled at this. He was glad his son was enjoying his father's huge dick~
Bowser went faster and harder. Junior loved every single moment of this! He loved his Papa! He loved his Papa's cock! He loved being fucked!!
"Mmgh! R-Right there, Papa~" Junior moaned. Bowser responded by thrusting even deeper. His cock hitting his prostate a couple of times. Though, if anything, it only gave Junior more pleasure~
Junior couldn't hold back anymore and came. His cum sprayed out and onto the floor beneath them. Bowser saw this and came as well. Roaring as he did so. "That's it, son! Take Papa's cum!"
Junior felt the warm cum inside him once more, his stomach getting bloated, making him look like he was pregnant. The young Koopa prince's eyes roll back as he moans loudly. There was so much! In fact, even more than before if that was possible!
"HHhahah... ahhh...! P-Papa...! Hhglk...!" He felt something in his throat, and he recognized the taste. He was trying very hard to keep it down, but was a losing battle. Finally... "BLEGHGHGHGH!!!!~"
He manged to puke Bowser's semen, staining more of the floor as Bowser watches this with a mixture of shock, concern and arousal. But he notices, Junior was blushing a deep red.
Once it subsided, the small Koopa male had his eyes half lidded in pleasure, catching his breath.
"Hhgh... ahh... I-I'm sorry Papa... I couldn't, nnhg... k-keep it in..." It seemed that was all his Son was concerned about.
He couldn't help but chuckle and ruffle his hair. He thankful he didn't hurt him, then again, they survived worse.
"You crazy boy... You definitely made me feel better." Bowser says, removing Junior off of his cock.
"Th-then... we can't do this anymore...???" Junior managed to say, salvaging whatever's left of his mind from the incredible orgasm. Bowser couldn't help but be amused. Did his Son think they would stop here? After all of that?
"Oh, don't worry, Junior." Bowser reassured. "This is only the beginning~"
All Junior could do was smile lewdly at this. Eager for whatever his Papa had in store for him…
[…]
Time had passed since the 'Nabbit Costume Incident'. After that, Junior and Bowser were closer than ever before. Bowser has since bought some revealing attire for his son to which he happily wore whenever he saw fit without any shame in the world.
None of the other Koopalings knew about yet, but both of them figured they'd tell them in due time. Other than that, both father and son were inseparable. They even tried out a few fetishes!
Junior was glad to have gotten the Nabbit costume. Without it, how else would he and Bowser have such an amazing relationship?~
