Slip those fingers back down your panties and start fucking your self slowly with three fingers.
With your other hand gently rub your clitty. Mmmm savour each thrust, take at least 20 seconds to go all the way in, and another 20 to pull out.
Do this for 5 minutes. If you edge, you will stop and restart the whole 5 minutes. If you cant get through the whole 5 minutes after 5 tries, then stop and rub toothpaste on the inside of your labia.
