i think having Brothel Workers entering the dungeon would be a funny story twist like all the adventures are taking there work.
They start entering with basic equipment (like warriors with dagger, rogues with crossbows, and mages with pink gems (that they borrowed from work)
the next day skeleton pops up and says something like, ‘the dungeon monsters are feeling sorry for the Brothel Workers as they can’t beat the slimes, so just give them only what there looking for’. Then enchants the monster scroll to show a heart with eyes for them.
(So they could be a mage in black with a red gem holding a crossbow with a line attached. But in the text box say, “I hope the bees make me lactate everywhere and have a butt that doesn’t fit in common chairs”. So you only give her lactation and butt mix potion)
this adds to the story of the town we don’t see and adds new game mechanics with little effort.
