So has tried some goop quest thick gunge the last couple of days and what an experience.
Using gunge is so different to other substances. The way it clings is something else.

Tried it with a couple of play along scenes from Jeremy Custard, head dunks, clothes filling, rubbing it in.

Highly recommend it!

Thanks. I've got some powder (standard and thick) from Goopquest, which I hope to use soon. I already owe so much mess lol!
