Lustfell Fallen Human

The human fell into the underground under mysterious circumstances. Was it an accident? Were they pushed? Or maybe they jumped in. Whatever happened, they are now in the underground and have to look for a way out. They are a grown adult of high-functioning mental faculties, age 21+, any gender. They could either be you, your OC, or just a random human.

However, they are not Frisk. I personally headcanon Frisk to be a child, and no human child has ever fallen into the underground.

Lustfell Sans, aka Jam

Like his classic counterpart, Lustfell Sans is lazy, gross, and a pretty weird guy. He is considered ‘unattractive’ by most monsters, because he doesn’t put any effort into his appearance or mannerisms. He’s just himself. But he still fucks a lot. He’s very talented and surprisingly active in bed, often surprising his partners by his enthusiasm.

He mainly uses sex as a tool for comfort and distraction. He is usually anxious and in his own head a lot, so the distraction of getting his dick sucked or making someone else repeatedly cum is very welcome. He’s a switch and he greatly enjoys teasing others, to the point of making them cry and beg.

Like most monsters in Lustfell, Sans is a sadomasochist. He doesn’t seek power, but he enjoys it when he has it. He will always have Papyrus’s back and will not hesitate in protecting him, even if that means murder. But he’s so lazy and perpetually exhausted that he rarely gets into physical altercations. He’d rather sass someone off and teleport the fuck outta there.

He enjoys making dirty jokes, especially knock knock jokes. He’s always too hot and wears fur-lined boots to keep his socks dry as he marches around in the snow, trying to cool off. He doesn’t cook often, but he does enjoy baking, especially fruit pies. He plays the saxophone, which always annoys his brother, even if he’s playing well. He drinks hot sauce, his favorites being Tabasco and sriracha. He dumps it on all of Pap’s meals, which also annoys him.

Sans is aware that he is in a shitty smut AU that I created, and he fucking hates me for it. This has caused him to have existential crises on the reg and to occasionally break the 4th wall. He knows you’re reading this and he absolutely wants to fuck you (if, y’know, you’re into that). he is especially attracted to humans and he’s a chubby chaser. he jokes that they’re ‘easier to catch.’

Lustfell Papyrus, aka Pepper

Papyrus is a loud, boisterous monster who takes everything as a compliment. He uses sex and his body as a boost to his ego and sense of power. He prides himself on being the 'BEST SEXUAL PARTNER, EVER' and will not stop until his partner has one of the best orgasms of their lives and declares their love for him (or what he's doing to them, at least). He sees sex as both a way to boost his 'ALPHA VIRILE MALE' status and as a puzzle to be solved. Others gawking at him, blushing, or reacting to his blunt nature really gets his motor running.

He does have a dark side. He is a sadist, he enjoys having complete control over someone, and he enjoys pushing boundaries. As a member of the Royal Guard, he isn't above killing and has little regard for monsters outside his social circle. He has gotten into a lot of fights, which has left scars and chips across his entire body.

Although he is an adult, he can also be naive and childish. He can be very whiny and he doesn't appreciate being teased. He assumes everyone wants to have sex with him because 'WHY WOULDN'T THEY???' and sometimes only sees things at their surface level.

He is an amazing cook, one of the best in the underground, and he prefers very spicy food. He crochets and takes very good care of all his belongings, especially his leather boots and armor. He loves making evil puns and he hates Sans's dirty jokes. He wants to capture a human more than anything, which he believes would earn him a promotion to the Head of the Royal Guard.

Papyrus's relationship with his brother, Sans, is complicated. They are family and they always have each others backs, but they both annoy each other, to the point of getting physically violent. He loves his brother and also hates him for his apathy and for making them both 'LOOK BAD AND UNPROFESSIONAL.'

Do they have sex with each other? Yes. But they don’t like talking about it in public, as they don’t want to give the impression that they’re vulnerable due to their connection.

Lustfell Toriel

Toriel is one of the only fertile monsters who's capable of carrying a child to term. She has lost over a dozen of her children over the centuries. After enduring the tragic deaths of her last two children(one of them being human), along with the obligation to conceive another heir to the throne, she locked herself away in the Ruins.

Six humans fell into the underground before our human fell. Toriel obsessively mothered over all of them and watched them all leave the Ruins and die. Over time, she has become more unhinged and it’s gotten to the point where she becomes anxious if the human so much as leaves her line of sight. Although she means well, her manic behavior and bursts of rage prevent her from being the mother she wants to be. Her nurturing can also slip into something more... intimate than she intends. She takes offense if this is pointed out to her.

She lives mainly in isolation, meticulously cares for a giant rose bush, and thinks monster dust is a delicious substitute for salt. She often speaks with Sans through the door and has even let him in a few times, when her need could no longer be ignored. Sans is always happy to oblige.

Lustfell Flowey

Flowey is completely done with this shit. He has reset thousands of times and is always stuck in the same universe. It's essentially turned him into an apathetic eldritch god who has lived thousands of lives and hated them all.

He is miserable, he fucking hates everyone, and he's very pessimistic about everything. It's caused him to lose motivation for most things. However, he will still play around sometimes, since there isn't much else to do anymore.
