gently massage all your pantie area with oil until you are really excited and very very slippery, insert you favourite toy and wear your most sexy pants, drink as much water as you can until you are desperate to pee, then remove your toy and jump as high as you can on your trampoline until you have completely peed it all out of you.
You must hold it even when jumping for as long as you possibly can.
Then keep your panties on until bedtime.
