Go for a walk in the woods somewhere isolated and bring your dildos, duct tape, lube and toothpaste (Maybe a blanket for the floor too). A chastity device for the whole time is really recommended but if you don't have one, just remember that you can't touch your cock.

When you've found an area that doesn't get any foot traffic, take your 10 inch dildo and tape it to a tree at ass height or lower if you feel like going on all fours (which would be easier and a hotter experience).
Now, get naked and lube your smaller dildo before slowly inserting it into you.
You're going to fuck your butt with the 5 inch dildo for 5 minutes, while sucking the 10 inch on the tree. When you're done, put some lube on the 10 inch, turn around and enjoy the other view while inserting that dildo. It goes without saying that this time you're sucking your 5 inch dildo. Keep this up for 10 minutes, trying to simulate your prostate with long strokes when you thrust back and forth.

Now you're warmed up, take your toothpaste and put a blob on the tip of your smaller dildo. You're going to switch sides again, with the minty cock in your ass and the big one in your mouth. Keep this up for 5 more minutes.
Now, put a blob of toothpaste on the tip of the big dildo. You're going to switch around again, and like last time, this one will be for 10 minutes. As usual, try to stimulate your prostate and do big strokes as you punish your butt. Suck the small dildo as before.

If you want to unlock and cum where you are, you must repeat the steps with both lube, then toothpaste again. Otherwise, you need to wait until you're home
