Well some but most of the time only one stays idle for a while after it finished raping, not all especially the stage where those reverse vore gremlins just keep spawning and the level where you have to climb and break vines while avoiding 3 goblins at once. Most times I'd fail those struggle due to the overlap of buttons like A & D for struggling and ↑↓→← for instant break out from grab (which corresponds to WASD).Pretty sure they often wait for you to get back up before they attack you again
At least some of them do, iirc
