how do i orgasm quickly?

Im a 14 year old girl, i lick my fingers and place it on my vagina so its nice and wet, I grab a makeup brush and place it in my vagina, I get off to lesbian porn, or hardcore porn (im straight btw), I put my headphones in a put it on loud, sometimes I read sexual stories, or pages like these, youll know when you have orgasned because cum (white stuff) will cime out your vagina, and it feels soo good, hope this has helped

Let me show you..
