Bianca and Luna were having a nice comversation until wizmaask came up like the kinky wizard he is and decided to play a prank on both girls by filling their diapers with water to the very brim with his water magic at the point they both are now pinned in place with their diapers absorbing the water to their limits, Luna seems to be very surprised/shocked and even embarrassed due to having her diaper ruined with water while Bianca is pretty much enjoying the water inside her diaper just like the water type she is. i highly doubt wizmaask is going to stop filling their diapers sooner, maybe he will stop once their diapers have exploded as water balloons or until they tear open from not being able to keep absorbing the water.
