Chastity wasn’t so fortune as the other two, falling over as soon as she got out the door, with her skirt getting caught on a hook on the wall.
Rebecca simply strolled out and looked at Chastity who was sitting there on the ground. “Well I would of thought you would of preferred to been changed in private, but if you want to be publicly humiliated that’s fine”
Chastity face turned white, as she noticed changes happening. Looking down at her briefs she saw the satin slowly grow, turning more and more plastic and forcing her legs to just get wider and wider.
“Well class is about to come out, so I’ll just skip the rest of the change for now, at least you have protection for any little accidents you may have” Rebecca said disappearing back into the toilets.
Chastity tried to move, but as she did, a huge amount of crap started squeezing its way out, lying there in clear discomfort in front of what now had become an audience of students who just laughed at her situation.
