Summary
Bowser’s life isn’t going so great. His castle got haunted (a “friendly gift” from King Boo), his responsibilities are taking a toll on him, and his heart just about shatters when he gets a letter in the mail officially banning him and his family from attending Mario and Princess Peach’s wedding. The issue isn’t that they were banned, that much was expected.
The issue is that Junior thought they WERE invited and proceeded to tell the rest of The Royal Family. Now his kids are over the moon, glad that Bowser is over Peach, and so grateful that the Princess is being kind and patient enough to invite him and his family to her wedding.
Bowser’s family is his entire world. How could he possibly break the truth to them? He just can’t.
His only solution is to figure out a way to keep up the lie, long enough to somehow turn it into the truth.
Even if it makes him resort to lows he wasn't aware he was capable of stooping to.

Summary
Through a political marriage, Bowser will teach the Cosmic Protector all about sex, dominance and submission. Forcing her to experience endless pleasure, he'll break her into a cock-addicted slave who can't resist him. Erotica. Master/slave. Warnings: Sexual slavery. This is solely smut, not a political intrigue story.
Note: This is being rewritten, and the link to the rewrite is below, but this version is shorter and easier to get through, and might be preferable at least as a starter.

Summary
“A plumber’s job is-a never done!” Luigi quite suddenly exclaimed. Mario’s unamused expression made Luigi’s stomach do a somersault.
“T-That’s-a what you always said to me in the past, bro,” Luigi continued, quieter this time. “Whenever I would get-a tired or bored when we worked on pipes together… I just-a thought I could… get back to my plumber roots, like the good old days.”
or- Mario is growing increasingly suspicious of Luigi constantly leaving the house.
OR- Luigi feels like he’s not helping the Mushroom Kingdom enough so he decides to do something about it, by lying.
And if Mario finds out the truth, it could mean war.

What you don't expect is to be sucked into a world of stone and lava and meet turtle royalty. When you and Luigi end up imprisoned by the king, Bowser, together, you don't think it can get any worse,
You were technically right.
It only got better.

I love Link being a beautiful Twink.

Summary
Long ago, a greedy and selfish Queen struck a deal with a dark entity. She wished to produce jewels from her own body, to be rich no matter where she was.
The entity granted her wish, and she came to be known as the Jeweled Queen. Her tears became diamonds as they fell, her very sweat fell as orbs of topaz, and even her blood became glittering rubies as it flowed.
Soon, though, the blessing became a curse. Her kingdom saw nothing but invasion and conflict for many years because of their Queen's selfishness. When she attempted to strike another deal, the entity instead cursed her family.
"Every third child born to your house shall bear the same burden you chose for yourself!" At this declaration, the Brooklyn Kingdom's fate was sealed.
For years, the curse faded from memory, and the kingdom was left alone. Until one fateful night, when a certain King received an... interesting report.
What the heck is Luigi gonna do now?
