Get dressed first.

You decide it would be a fun experience to go to school as your sister in this enhanced body. As you go to clean up her body you notice that all the fluids from your masturbation are gone and you decide it had something to do with the magic side of the dildo making up part of your dick.

You manage to piece together some of your sisters memories which you gained after cumming in her body and manage to dress yourself. However due to the 'growth' your body recieved your sisters old uniform barely fits like it used to. Your blouse looks more like a crop top exposing your midriff and your skirt barely reaches past your underwear. Your dick has also magically disappeared when you put your panties on. You can still feel it as if its there but its hidden away.

You leave your room and come face to face with your mom.
