Yes and immediately regret it.

You smile at the thong and pick it up.

"Ok you're first buddy!" you grin.

You quickly step into the panties and pull the flimsy bit of material up till its hugging your pussy and riding nicely between your ass cheeks. You tug it upwards till its around your waist.

Immediately after letting go of it though you feel it tighten around you and mold itself to your pussy.

"Hey! What the hell?"

Several tentacles shoot out from it and wrap around the tops of your thighs and waist, even over your butt cheeks, tightening down while at the same time the inside of it comes alive with a wave of small tentacles that start feeling you up.

"Oohh.. i dunno what's going on but can this be a good thing..?" you wonder, you try to grasp at the panties and tug on them but they are surprisingly resilient, able to be pulled away a little bit before snapping back against your skin quite hard.

You could try tugging at the harder to remove them, or maybe grab a sharp rock or something else?
