Now I want you to remove your panties. You may either use you fingers or a vibrator/dildo to bring yourself back to the edge and hold it for as long as you can but do not cum.
If you accidentally orgasmed I want you to stop and ruin it then smack your pussy with your hand 10 times each one harder than the last. Both your pussy and your hand should be aching. If not, do 10 more.
Then continue.
