Get in your living room, open the window curtains and place a chair in front of it. You should be able to sit on the chair and put your feet on the window. Write "Dirly girl" on your boobs and put a clip on each of your nipples. To make it easier for you you can blindfold yourself. Sit on the chair with your legs on the window. Keep them spread so that your pussy is visible. Stay like this for 10 minutes while carefully rub your nipples, boobs and tights (no pussy or clit touching). After that for 15 minutes start playing with your pussy, rubbing and inserting fingers. You are not allowed to put only one finger (at least two, bonus points for more :P give the people a good show). You are not allowed to cum at all. When the timer expires, you have to carefully remove your blindfold before moving your feet off the window, getting off the chair or do anything else.
