Just bought a fresh pack of briefs

[selfwedgie13]

Maybe you could try this: put one pair of briefs on, pull it into a wedgie as high as you can, then tie it in place. Put on a second pair, pull it in a melvin as high as you can and tie it in place. Then put on a third pair, pull it as high as you can all around and tie it in place. Then keep all three wedgies in for three hours.
