Since we don't have much information about this 'Big Penis Brother', we can assume different things. If it's a fantasy story, his sleeping could be enchanted. Maybe an evil wizard has put him to sleep and the story could be about how his friends try to wake him up. They might have to go on a long journey to find the antidote to the sleeping spell. It could also be that he's sleeping in a magical place and his sleep is protecting something valuable, like a hidden treasure or a powerful magic item.

The big black brother and sister grew up in a big family. The brother was older and would help his sister with her homework. He was really smart in math and science.

This kind of plot involves violating ethical and moral norms. Sibling relationships should be based on pure family affection, such as sharing hobbies, helping with studies, and protecting each other from harm, rather than having improper seduction.
