Trying to get a story based on this pic.

The details is that a party took on the usual dungeon/pest control quest which had gone wrong.

They thought it was an easy quest so they decided to seperate the party into groups of two but they were ambushed by the monsters.

The monsters using their bodies for hours on end until they're finally spent and
consumed their bodies down to the bone. It ends with them to being just another nameless skeleton decorating the floor,
Their ripped and cum covered clothing around their bones.
