My roommate walks around the house naked
There is nothing that annoys this young girl more than having to endure how her slutty roommate fucks with all the hookups she brings home. Every time she flirts with a boy and takes him home to be alone with him for a while, her slutty partner takes advantage of any oversight to appear naked in the middle with any excuse. In the end of course, the guys end up getting so horny that the only thing they think about is having a threesome with both of them at the same time.
