You don't.
This can be considered sexual harassment and is illegal.
you touch one part of the pant and gently ease your way down
If you have to ask this question here and not to her then it's apparent that it's not consentual and is considered rape. Do yourself a favor and don't do it, find a girl that asks you to do it and then tells you how.
You rub her first on her boobs the you pull down her pants and rub your penis every where around there and maybe have some sex.
Gravity and the weight of the door assist in making it easier to pull down than to pull up.
Because they are to big. Put a belt on.
To be sexy perhaps.
