Slimy Microvilli (Patreon)

Shawna was walking in a dark mansion's tiled floors, raising her eyebrow at the random cracks oozing with pink liquid. All hell broke loose when a section cracked and gave way to a large hole which she fell through. She plunged into a pink, slimy basement full of wriggling fingerlike projections.
