Honestly? I thought it was decent.
People saying it was a cliché, no character development, short sentences...
It accomplished your intention just about well. You don't care about characters in a short story. Emotionally binding to a character is a long process, there is absolutely no need here to describe the boys, they are just a 'tool' used to develop the story.
Short sentences - again. It fits great. You don't want to have long, elaborate sentences in an action filled scene. Text writing 101. You want them short, precise. It gradates the situation - perfect.
You had a couple typos {too - to}, tenses didn't match {you started a paragraph in the past tense, used present tense in the middle}.
But overall, decent. Really liked it :)
