Showering after Gym class

Reina had just finished Gym class and was feeling exhausted from all the running she had done, as soon as she was in the locker rooms she opened her locked, undressed, and put all her clothes inside before locking it back up, she then headed towards the showers with the other girls and enjoyed a nice loooong shower.

Many girls had already started to leave the shower but Reina wasn't in a rush, she honestly considered skipping whatever she had next to just shower for the full hour, the warm water felt so nice running over her aching body.

By now Reina was the only girl still in the locker room... which she finally had noticed, Reina decided it was finally time to get out, she grabbed her towel and wrapped it around herself before heading back towards her locker, however... when she reached it, she was shocked by something.
