Fluid

You decide to investigate the strange fluid in the cell. You enter the cell and kneel down in front of the substance. There isn’t any evidence of the fluid corrosive on the floor. You don’t smell anything strange either. You take a finger and poke the fluid. It is a viscous goo that sticks to your fingers. Before you can stand up, the slime starts to take a humanoid shape. You’ve just wandered into a trap. The blue slime reaches your height and forms arms, legs, a faceless head, C cup breasts, and a ten-inch cock.
