*UPDATE: All ranges of Undertale smut/lemons (mostly lemons by this point) No longer one shot. Contains multiple one-shots, and occasionally two-shots. Male readers can request a character x male reader :) Underfell Sans x Female Reader. Smut or a Lemon *shrugs* might be a one shot (if no one wants more I guess)

Warning, this is a lemon book. If you are uncomfortable with skelotons and readers getting it on, don't read XD OC request guidlines: -Description of appearence -Description of soul -Any kinks He/she may have -Which sans He/She likes -Personality (WE NEED THIS IN DETAIL) Thank you. If you have any more questions, just ask us in comments, we will answer A.S.A.P. :)
