Senko's study session

"Uyan! It seems you are working very hard on your studies today, mofu... and so am I! I wanted to help you by taking notes with my notebook and pen, but... oh dear, my bad! Hehe! I guess I got a little too focused and excited, and my diaper got all wet and heavy. It feels so funny and wobbly to stand like this, mofu mofu... Let's take a little break so you can wipe and sprinkle my soggy bum-bum, okay? Oh, you need a diaper too, dear? Then come along! I can change your undies as well, mofu mofu!~"
