Adopted By Monsters -Undertale × Baby Reade...
Spoilers! If you have not seen both pacifist and genocide routes of Undertale, get out! You have been warned!
Sans finds a baby on the streets. The monsters of Undertale decide to adopt them. What can possibly go wrong? More than they thought.
Undertale, images, music, and all that stuff does not belong to me. All credit to them!
