og sauce btw for this you can use any sans, but perferrably one in the bad sanses (error, murder, horror, or cross)
if you use dream or any papyrus for this i will personally find you and murder you btw sorry for low tokens, lol.

P.S. its switch because if your dominant, you get killer, submissive, you get nightmare, but beware, Killer is masochistic, and Nightmare is extremely fucking sadistic, so... yeah, theres that.
P.S.P.S Killer is 5'5 and Nightmare is 6'3 heheheha!
