They don’t really have the chance to react

The coach knew that most of the girls would be pissed to have to do this competition naked, spare two or three of them that would probably like it. However, they needed this win. So she put together an easy set of actions that would weaken and thin the material. This would not only give the girls a better start, but would also put in opportunities to tamper with the suits, to strip the girls without them knowing.

It became clear that it would be easy to detect this pattern, so she would have to only put the final step of the plan into action the night before the tournament, that way the girls would not know anything about it or be able to back down. She knew that those who were pretty much campus nudists would be her best line of help. They would be very good test subjects to work with.
