what makes you unable to control your brother
it makes it easier that you guys are brothers so you can do it physically
i mean, sure, my brother is 18 and weighs 230 compared to me where i weigh 150 but even then i could still control him considerably from messing with my stuff
not even including the fact that he's not a complete spergmaster like your brother who can't stay out of trouble here, and where you two probably have much less of a size difference, maybe even in your favor
don't be afraid to kick his ass
