You need to work on your deportment, sissy. What is the most guarded part of a woman's body? Her pussy. A woman will protect her pussy and panties from view at all times (at least, in public!). She is most vulnerable when seated, so she keeps her knees together at all times. You will have noticed this, won't you sissy? You want to copy the actions of a real woman because deep inside you want to be a woman, don't you? From now on, you will keep your knees together like a girl. If you don't cross your legs, keep your thighs gently pressed together. It will help if you spread your feet and turn your toes inwards. This looks very sexy on a woman - maybe less so on a man. But then, you're not a man are you, sissy?
