Summary
Lark came to the aquarium as a pup. He didn't know who or what he was before his life here in captivity. In his blissful ignorance he grew among the humans that cared for him, the crowds that came to see him. Being a lesser siren, his songs soothed rather than tempted, his instincts not strong enough to produce more than ease and healing upon those who heard him.
It's what had made him so popular.
His tank was open to the air, shallow near the glass where humans of all ages would stand waiting to hear him. Waiting to get splashed on the outside portion of his enclosure. On the inside, it was sealed and sound proof, his songs reserved for those who paid the most to get outside. He didn't mind it. The extra profits meant extra food for him, and good quality water. Or that was his limited understanding of how things worked in his very small world.
Small but comfortable. Till everything changed.

The island had been forgotten for a long time now, the monsters believed that they would now live in peace on their island far from the human world. But humans are the most megalomaniac beings of all. Eager for riches, they began to plunder all over the island, and the monsters were unable to counter them. But what would happen if a scientist and a monster agreed to create new life forms, to stop all this?
Our skeletons will have DNA from dangerous animals inside them!
O and the island suffers from a shortage of females so... it will be fun🤭

Got some non-con, because Night obviously didn't consent, but in this one the passive Night is at least 18, so not underage and aware of what sex is etc.

I have an insatiable lust and love for Papyrus by Zooper95_freak
Fandoms: Undertale (Video Game)
30 Sep 2025
Tags
Summary
Kinktober? except it’s all classic papyrus and im not following one of those image daily prompts and this all from the pool of depravity and lust all within the deep dark depths of my mind
That was exaggerated and quite crude,
I really love Papyrus but the already little amount of media with him is AUs or just tagging him cause he’s mentioned or shown in the background and you know what they say! -

Summary
These are a series of short stories with variants of Sans from different AUs for a potential bigger fanfiction I wanna write in the future.
In these stories, Reader is Gender Neutral and is Referred to as Yin(short for Y/n for convince). I will NEVER describe the Reader or their appearance, there may be times where I have the reader wear clothing and describe it, but it will not be very often so you are free to imagine any outfit in these scenarios that fit with the setting. For certain Sans AUs, I may make you shorter or taller based off my own headcanons for how tall characters are, but that is as far as it will be. For Oneshots with sex or similar stuff, gender neutral terms and compliments will remain as well, but I will write separate sections for those that have either parts.
Terms of endearment will be gender neutral, compliments will not fully describe your appearance, etc. I WANT THESE STORIES TO BE ABLE TO BE ENJOYED BY PEOPLE OF ALL SHAPES, SIZES, ETC. IF YOU FEEL SOMETHING COULD BE BETTER, LET ME KNOW IN COMMENTS HOW YOU FEEL AND FOR CONSTRUCTIVE CRITICISM. THAT IS ALL, THANK YOU FOR READING AHEAD!

i was meant to be yours (you were meant to be mine) by necropathy

Summary
The urge to hiss and spit clawed at his throat, but he forced it down. His survival depended on keeping Sol’s guard down. Any sign of defiance now would only tighten the noose. He had to play along, to behave, even as every instinct screamed at him to fight back.
He stiffened as Sol’s hand traced a soft, burning path down his spine, the touch almost tender through the fabric of his clothes. It took every ounce of willpower not to flinch away, especially when Sol guided him down to sit, his fingers deftly beginning to undress him.
The intimacy of the act made his bones crawl. But he swallowed his revulsion. Resistance would only make his escape harder.

Summary
Starvation and desperation has run rampant in Underswap/Horrorswap Sans' AU for weeks. And with his friend and royal scientist, Undyne having nearly succumbed to malnutrition. It's up to Sans, the new interim royal scientist to solve the crisis before the returning king Asgore is ousted from power.
His weeks of research and isolation in the royal lab culminates in him believing he's developed a small yet extremity calorically dense food source in blueberries; grown in Determination (DT) and Perseverance (PV) enriched soil. With time running short and his own hunger beginning to set it. Sans makes himself the monster test dummy.
Good news; it looks to work
Bad news...just a few very juicy, very inflammatory, very mind altering, and VERY permanent side effects.Welcome to Berrytale
