It should be revised to this.
Mike and Reed are brothers who live with their parents. One weekend the parents take a trip to another city. Now that the parents have gone Mike decides to leave with his friends for the night,now his brother Reed is stuck house sitting. Reed decides to make the best of the situation and invites a bunch of his friends over for a house party.
You need more descriptive sentences as well as maybe a few things to make the story less point blank. Your readers are wanting to get to know your characters so instead of saying Reed and Mike are brothers, you could go more into length and say Reed and Mike come from a small family of Four Mike lives with his younger brother Reed his mom and dad and their tank of goldfish. Something to make your readers want to like the characters.
