One of the spiders melt into your chest as you try to free your legs from the webbing, having dropped from the darkness. You let out a cry of surprise, one of your arms reaching up to try and tug it away to no use. You can hear more approaching, webbing shuddering under skittering legs.
The goo on your chest spreads, connecting with some of the webs, which melt into more slime to your panic. More webbing splatters onto your head, more slime than solid, and you try to reach up only for more of the silken threads to wrap around your wrist.
Another spider melts into your back, a third arm sprouting from the goo and beans squishing together. Something emerges from your mouth, your startled cry turning into a chittering noise. A third spider drops onto your shoulder, more approaching from the shadows earnestly to change you quicker, to make you into something like them.
Perhaps you should worry as your panic slips away as more bodies and minds are added, but your fur feels so very nice and the smaller spiders are rubbing against you like some sort of happy kittens that you can't bring yourself to be mad at their actions. Perhaps this isn't too bad...
