While there is no way to permanently fix the bicycle tire without using a repair kit or going into the bicycle shop, here's a thing you can try:
You will need: something to tie the tire tube with and leaves or other similar material.
1. Take off the tire from the wheel.
2. Take out the tube from the tire.
3. Find where the puncture is and using whatever you have, tie several tight knots around and on the puncture to create an airtight seal.
4. Fill the inside of the tire with leaves or other similar material. This will help keep it in shape and apply pressure where the tube should.
This should allow you to travel long enough to get the tire properly fixed.
