As a reward, you descide to suck him, after he gained some energy again.
"Are you sure?" he asks while you already take his tip into your mouth while nodding. You try to make the most innocent face and look like a depending little girl while sucking him.
"You look kinda stupid, ya know", he says partly as a joke, but partly serious.
But yes, you look stupid. You WANT to look stupied. Stupied for him, your beloved boyfriend. No good grade could achieve what he made you feel today. You are "dependent" but only to him, for him. You are his little blond and "stupid" girlfriend.
Tomorrow you will rule the math exams.
