My Little Puppy (Fell!Sans x Wolf!Reader)

(Y/N) is a human. She had lived her whole life as Sans and Papyrus's pet, which was even more appropriate considering that Alphys had done a few experiments on her giving her dog ears and a dog tail, as consolation for keeping her a secret.

Then one day, (Y/N) manages to escape, and meets with Frisk. What will follow after that, with her trying to escape and Frisk's shady actions? Well, you'll have to read to find out, now won't you?

*Warning: cursing*
( Also, it might get a bit [Toasty!] at some point or other, and don't read if sensitive. ALSO also, we don't update often so CALM YO TITTIES.)
*😑*
(Whaaaaaaaaaaaaat?)
