Underlust is an AU made by NSFWShamecave, who temporarily gave permission to Skele-cakes to continue the AU. NSFWShamecave has since taken back the AU. All the characters are overly sexualized and search for sexual attention except Mettaton who was a victim of sexual assault/rape.[1] Everyone typically wears revealing clothing. Certain locations, such as Grillby's are also changed to fit the theme.
- Backstory
Sometime after being sealed Underground, monsters began to suffer from widespread infertility, and their numbers began to dwindle. About a decade after the son of Asgore and Toriel had been stillborn, a human fell into the Underground. This human, named Chara, had the SOUL TRAIT of LUST, and soon after entering the Underground began murdering all monsters that crossed their path for their own sadistic pleasure. Eventually, this Human was killed and their SOUL captured.
After some time, it was decided that the monsters would use the SOUL TRAIT, LUST, in a fleeting attempt to raise the fertility of monsters and save their people. The duty to preform the injections was set to Doctor Gaster, who was to inject everyone of age with the LUST, including himself.
Although it was never expressly stated whether these injections succeeded in raising the fertility, what the injections did manage to do was make sure every adult monster in the Underground was put into a "constant state of heat". Ghosts are the only exception to this, as they lack a physical form.
Eventually, a new human fell into the Underground. A human named Frisk, who would make it their personal mission to show the monsters of the Underground what true love is, and how it is more effective than lust.
