Summary
This takes place in a post Underfell King Papyrus ending.
Struck by under population, King Papyrus makes it law that all monsters left alive by the murderous little human have to procreate. This leaves Fell!Sans and The King himself in a tight spot. There are no female skeletons left in the whole Underground and both skeletons are sure they are the last of their species. Fell!Sans proposes something. With the help of the first Royal Scientist's machine to travel to other universes, he will find mates for breeding purposes.
Tale!Sans is having his first sub heat as a female. This happens when there are only males left and the strongest one undergoes a gender swap. He knows this means Papyrus will have to be his mate.
That won't do. They are brothers, for the Angel's sake! So he does what he does best, HE RUNS.

Summary
It was just supposed to be another in and out. Steal what was worth something and skedaddle. Back to...well, they didn't exactly have a home. Not anymore. Wasn't important.
Back to the issue at hand.
How were they to know who owned the place? What kind of right hand of a powerful mob boss lives in the suburbs? Why does the house look so normal? Why...
And they have a sex dungeon.
Awesome.

Summary
Welp. Here we are. I'm doing this trope because I wanted to put my own take on it. There's a lot of skeletons and there's only one you. At least the only other human in the house is only rooting for you.
