Firstly its Came you dumb slut, And because of that you are to stuff your dirty panties into your illiterate mouth and Spank your Cunt 10 times, then you may return to your edging.
Simple answer is treat the toothbrush as a vibrator. Unless you were ordered to use the bristles turn it to the back side and work your clit how it feels good. Insert two fingers about 2 inches and between 11 and 1 on a clock play with your g-spot. Be alone and just relax and let it happen you will experience a great orgasm.
