"Now then I'm going to turn the three of you girls in to some nighttime diapers." the head master tells them, "now don't you girls worry this change is completely reversible once your completed your initiation."
Jess grins at him, "Are we going to be boys pants or girls diapers?"
"Girl, the three of you will be warn by girls, it just be who ever picks you up. Now no more talk we need to get on with this." he replies before pulling out a tablet and entering some commands.
Moments later the girls feel their skin start to tingle as their clothes disappear leaving them naked and on display to the room for a few seconds before the transformation takes hold, Just like when they transformed them selves earlier their faces stretch out forming the soft padded inside of the diaper, but unlike when they transformed them selves this time attention is paid to their sex organs a well their breast becoming the front outside, and clit the bottom such that if their wearer decides to play with them selves through the diaper they will also be stimulating the girl. Less than thirty seconds after the transformation started they are nothing more than a diaper laying on the floor.
Cassie projects her thoughts to the other girls, "This is so cool, did you feel what it did with our special parts, I hope who ever wears me wants to play with them self." causing Jess and Kate to giggle in excitement in each others minds.
Kate asks "Hey Jess will this telepathic work with other people as well, like will we be able to talk to who ever is wearing us?"
"I'm not sure, it should"
"Cool, this is going to be so much fun," Cassie giggles.
Then they hear the Head Master saying, "Yes take those new diapers to the supply room, make sure their on top, I expect them all to be used tonight." Moments later they are pick up and piled on top of each other before being take away, after a few mintues they feel them selves being laid down on a pile of unused diapers just waiting to be used.
