Light It Up
I like to take one of those light up wands and use a little lube and penetrate myself with it while in a doggie style position. Then while I thrust the light wand in and out of me I take my other hand and use two fingers to circle my clit fast till I'm going to explode. Then I stop rubbing my clit for a second then start again and it feels so amazing.
Light wands can be substituted for other dildo like objects of your personal preference.
