HELP ME FIND THIS MARIO FANFIC

okay here's what i remember
i read it about 2 years ago i'd say? it was about the reader being sucked into the Mario universe, and they, along with the Mario brothers have to go and find a way for her to get out. they find a prophecy i think, and use that to travel to bowser's castle, who teamed up with king boo.

specific things i can remember:

-they went to a water level where Mario gestured the reader to breath normally, and they had to trick her to breathe in the water. when they were on land, she threw up all the water

they came to a sky goddess castle??? they spent the night after the reader touched an orb and was able to communicate with the gif residing there, and after sleeping in rooms that appeared out of nowhere, the goddess launched them in a canon i think?

king boo possessed reader

the final battle was in the real world

the reader had a choice of either staying in her world or going back to the Mario world, and she went back to the Mario world.

i think the author made a sequel??? can't remember.

thank you if you can help me!!
