A slug slowly approaching

Hopelessly caught up in this sticky black webbing you struggle to look over your shoulder.

Approaching you slowly was a large flat slug creature. Midnight shiny black in colour with a silver coloured skirt, you can see a wet trail of latex in its wake as it approaches your bound form. \Evidently not the creature that created this web trap, it seems to have decided to lie in wait while the web builder went off to search for other prey.

Its patience was about to be rewarded.

With your arms tangled up and your legs effectively tied together on the trap you can barely see the slug as it stops just short of you. You can see it extent an antenna tentacle thing from its head and aim it towards the webbing at its anchor point and shoot some type of substance at it. Immediately you feel part of the webbing jerk and drop away, cut by the slugs fluid.

Struggle as you might though, the remaining webbing around your limbs and body is still holding you in its tight grip.

Again the slug shoots another round of enzymes at the webbing's anchor points, one by one deforming the web and eventually you land on the ground in a heap, still struggling to move.
