The Moth and The Skeleton (Underfell) by Butterflyx06

Summary
(y/n) was visiting her cousin Muffet at the bakery for the weekend. It wasn’t often she ventured out of her little nook nestled in a cliff in a waterfall. The ever growing eco flowers made it so she never had to go too far from her house to eat. Plus, her solitary lifestyle is one she cherished. Muffet saw this differently though. She thought (y/n)’s homebody tendencies were unhealthy and “further weakening her already pathetic constitution for confrontation”.

Summary
“Sans, have you considered… that you might be... in heat?”
“hate to break it to ya, flame boy, but skeleton’s can’t do that. im just as disappointed as you are, i know. the bone zone would have made a great pun to use someday. too bad it don’t exist, right?”
Grillby damn near dropped the glass he’d spent the last half an hour polishing.
-
Or, in which Sans learns that skeletons can go into heat, and Grillby awkwardly offers his assistance. (This was supposed to be pure smut but the first chapter is literally just plot buildup lmao im so sorry) -

Summary
Tiffany Loves was nice and pretty, looking for a place to rent a room while attending college to be an artist. She finds herself staying at a mansion with eight skeletons and becoming friends with all them. In fact thanks to soul bonds she has become a lot closer then friends to them…
This story though is a lot less about her and more about a certain assistant, the student majoring in engineer at the same college and assisting Sans in fixing his machine. His also nice as far as he knows, not bad looking, but never the focus of much attention. The stand-by friend for skeletons when Tiffany was too busy. He was ok with it because one specific skeleton appeared to like him a lot and he liked them very much as well.
But then he finds out he was second fiddle even with that one skeleton compared to Tiffany. He leaves the assistant job swearing to have nothing to do with skeletons. Something goes horribly wrong with the machine though and nothing is going to be the same again. A little twist on the typical reverse-harem story.
Update- So Sammi Bold did a podfic of my fic and put it on youtube. Put details on the last chapter of this fic if anyone wants to listen.

My favorite reverse harem/hate harem trope, with good character writing, good reader writing and male reader!!! This work feels so good, and even though it could be continued, it’s still so good as a stand alone story!!! This story is one of my favorites, and I reread it constantly!!!

Summary
Inspired by DarkxSoulzyxCaliberx comic. Their comic was 'what if Killer died and got replaced?' The comic is amazing and work safe.
My story is not work safe. This story is "What if Horror does? How will the gang react?" A more detailed summary will be the first post, explaining the tags better.
Horror is the ONLY Main Character Death, and it is brief.If you don't want to read the sex scenes, I will post an edited chapter in a collection.
