Erin Timmons is the second oldest of the Timmons siblings, followed by mere minutes by her twin brother Ryan. She, by far, possesses the most amount of sex appeal out of her siblings. At least, according to her.

Erin grew up as a middle child, so she's never been bored, and is used to having many people around her. One of her favorite pastimes, along with Ryan and Connor, was to pick on her younger brother Kyle. That pastime has almost blossomed into a full-on obsession, as she now thrusts her full-blown adulthood in his face on a regular basis. Unfortunately for Kyle, he seems to be the only one of her siblings that can take the abuse constantly. Because they're so much alike, they often find themselves annoyed greatly by the other.

Erin has always knew that she liked both genders, and it never seemed like much a big deal to her. This is probably because all three of her brothers are so enthralled by the opposite gender, and so she had much access to pornography. The only person that still remains clueless about her bisexuality is her mother. Due to her deep Irish Catholic upbringing, Erin thinks that this is for the best, since they don't always see eye to eye.

Jason was actually the one to teach Erin how to play drums, as an incentive to get Kyle to practice more. When Erin was 15 and Jason was 13, he taught her the basics, and Erin picked up the rest quite naturally.

Although Erin is still technically a junior in high school, she could quite easily be a freshman in college. Since Erin has jumped from private school to private school during her teen years, she hasn't been able to keep up with her studying. Being kicked out of private school has almost become a hobby with her, that her mom has finally given up and put her in the same public school as her brother Kyle.

Surprisingly, after thinking about what she wants to do after high school, Erin thinks she wants to go into teaching. Probably high school.

Well, if she gets the attention there now, why not?
