Στρινγκ κρεμαστή σφήνα

Trying to get the best thong hanging wedgie the completely rip to shreds 4 pairs on thongs. 2 thongs slowly and gently rip. While 2 thongs snap off completely with one big rip. One of the rips sends me crashing to the ground. I start with hanging wedgies low to the ground and slowly work up to higher off the ground.
