You need to grab her leg, arouse her a little, let go of her leg and wait for the blue bar to drop, do that second time and you should be able to remove blanket. The whole aroused/awakening system is a bit complex.
And after that? Both the boob and stomach options jack up the awakening meter, while the pussy options don't really seem to be doing much
Grab her leg and boob at the same time, but leg must be first, it's corelated.
Ok, i added full Walkthrough. The mechanics are more difficult than I thought.
thank you its pretty good now that I know what to do
