Summary
The Mushroom Kingdom has obtained a new advisor, that being Luigi himself. To obtain the role is a deep privilege and should be respected. You know everything and see everything, there should be no reason to keep something that would end up coming to light eventually.
What would cause him to cross his fingers behind his back?

The first time was a mistake. Honestly Luigi was too scared to confront anyone, especially not the Queen of the Koopas. Yet here she was finding room in her schedule for small talk with her previous captor.
Basically just Bowuigi yuri

Both kingdoms recognized that a major change needed to happen or else the destruction and bloodshed would continue to be endless as it had been for years.
Both kingdoms recognized that everyone was a tad surprised and shocked that it was Bowser, who was the first step forward and extend an olive branch and begin peace across the world.That was a year ago.
˗ˏˋ ★ ˎˊ˗
Mario and Luigi, Princess Daisy, Princess Peach, and none other than Bowser himself are all friends and just want to have a good time and live their lives.
How does the group celebrate?
With childish sleepover games like Truth or Dare, of course.What happens when Luigi is dared to dress up as Peach and maybe gets a little carried away?

Summary
“That’s not how babies are made! Who told you that?”
“No one. I just saw it by accident on a movie. It was an adult movie that I accidentally stumbled upon while channel surfing. Of course, I didn’t watch the whole scene. Because, it was too embarrassing to watch!” Luigi says as he covers his face in shame.
Bowser grunts as he feels his already fully-hard cock grow even more. This kid will be the death of him. How can he be this… virginal? He licks his lips and looks down at the naked and mousy boy.
“Luigi, why don’t I make you a deal? You get these chains off and I’ll teach you how babies are actually made. You don’t want to turn 21 and still not know about these things, do you?” Bowser asks in a suggestive tone.
“N-No, I guess not.” Luigi says with hesitation.
“Good. Now come and free me. I’ll show you how things are done.”

Summary
Luigi accidently breaks the jar that Bowser is confined in. It just seems to be one screw up after another, and who's left to clean up these messes?
Mario.
Annoyed of that, he sets off to make things right. Things don't necessarily go as planned. The capturer ends up becoming the captured.
. . . . .
"Enough, Kamek. Don't kill him." The king signalled him to stop. "Get out of here and leave him to me. No spells.""But sire." The wizard protested. "You can't trust him. He works alongside Mario. There's no telling what they've schemed up-
"That's an order. Plus this guy is no threat. Without his brother here to save or defend him- I'm sure he'll be as cooperative as a trained dog." Bowser grinned, leaning down so he could hover over the man who was lying down on the stone floor, small puffs of air leaving his slightly parted lips. "If he becomes a nuisance or I simply grow bored, I'll kill him."
Kamek nodded. "As you wish, sire." In a poof of sparkly smoke, he was gone.
"So, greenie. It looks like it's just the two of us."
Bowser x Luigi.

Summary
When he was younger, his mark seemed innocent. The words were easily explained by a child’s play pretend at school or in a park. His Mama caressed his cheeks and told him he was going to be lucky to meet his soulmate young, that after their eyes met, they would dance around each other for the rest of their lives. Mario believed it, too… but with each year that flew by, as Luigi went from small boy to teen to adult, the story became less likely.
His mark became an embarrassment. It became something that caused his family shame. His soulmate was either being sarcastic and mocking him or he was… well… insane. After all, who was planning to marry a princess and rule the world in Brooklyn?
[In an alternative universe, everyone is born with a soulmark, but it manifests on different species in different ways. Humans wear the first words they hear their soulmate speak, while Koopas wear the last words their soulmate speaks to them.]

Summary
For years Bowser had suffered an affliction. Yes, for years he has kept his illness as quiet as he could. For years Bowser, the powerful, frightening, temper mental King of the Koopas, had been coughing up flower petals.
Whenever his heart would yearn for a love unrequited, he would choke and gag as flowers clawed their way up his throat. Bloody and sore, he fought through it for a long, long time. Kamek had watched this for years as the illness ate away at him, wishing there was a way to give the King the love he so desperately desired. -
