What's Fontcest? It's a Undertale ship between Papyrus and Sans. What? They're brothers? Yeah I know, but they're fictional skeletons in a video game. No kink shaming please. We all have weird kinks like "Daddy kink". Please don't come here just to send hate. I'm warning people before they even look inside. If it's not for you then turn around. Warning: BoyxBoy, Skeleton Incest (lol), Smut, and Swearing.
