Stab it!

With rapier in hand, you jab the blade into the middle of the monster and... instantly regret it. You remember that this monster eats inorganic materials and your sword is a tasty snack! As you pull it away, you see that half the blade has been corroded away, leaving you with a useless weapon.

The ooze gives a small squelch that may or may not have been a burp. If a slime could look smug.....

Rearing up, the thing attacks! It latches onto your skirts and starts disolving them away! In just a few seconds, it has eaten through both them and the trousers beneath, exposing your shapely thighs in the process. You are quickly divested of your lower graments and give a small moan as the tendrils start massaging your womanhood as it burns away your panties.

It's then that you see the looming shape of a much larger purple ooze, emerging from the tunnel you noticed before... this was a trap all along it seems.
