Theory over Practice

"You will do anything I say? Answer truthfully"
"I will not do anything you say" Just for once your brain was doing the work, you found that with such a weak compulsion you can tell truth but not the truth she was looking for.
"And yet, you won't move an inch because I told you not to move half an hour ago. Interesting"
She walks around you as to inspect you. You try to keep her in sight but your head barely moves. She stops for a moment behind your back, before doing a full circle and facing you from the front.
"Look me in the eyes!" look her in the eyes!
You of course obey. Moving your head down just enough so your eyes can meet.
"Explain to me in full how this works!" Explain to her how this works!
There wasn't much you could do to wiggle out of this one. Direct order, decently formulated. Compulsion to tell her all you knew was to strong. "Because you defeated me in battle. I will now obey all of your orders that are possible for me to carry out." You felt that's actually enough to satisfy the order.
"Oh. So you will obey anything I say as long as it's possible and you consider it an order? You were trying to be sneaky before, how naughty!"
You stood there, completely and utterly humiliated. It's over now. Any chance of gaining freedom back - pooff - gone.
"Answer all of my questions truthfully from now on!" Answer all the question truthfully
Tears form in the corners of your eyes, tears of humiliation, and tears of rage.
"You were going to attack me then! You were not joking!" Sudden realisation hit her. She paused for a bit. "Oh right. Not a question. I see you're still playing. Very sore looser you are. I might have to spank you." she flashed you a wicked smile. "In fact ..."

Active compulsions: Don't attack again, don't move, be careful where you step, Answer all the question truthfully
