Finish my work or visit the toilet?

Description:   good girls get there homework in on time no matter the cost, still wearing my uniform (cosplay) i sit on the playroom floor and try to tackle my homework. its super hard to concentrate on each of the questions because i really need to go but my homework much more important than a silly toilet trip, as i get visibly more desperate grabbing onto my crotch to try and hold it. pulling up my skirt to show my kitten paw diaper. i realise its no use and i start to wet my diaper, watch as it fills up the front swelling with the amount of pee. but like any good girl i carry on with my homework.
