Child porn? Or sext gone wrong?

A highschool basketball team who has been together for 5 years is almost destroyed over this:

Everyone is sitting in the locker room all having a great time. Music is playing people dancing, Till Ashley (names have been changed) relizes her shirt had made her armpits turn black. freaking out and being at a away game she gets in the shower in her bra and underwear. Maria decides it would be funny to pull the curtain, but rachel said let her get it on video.
