I bring my freshman sister (https://www.manyvids.com/Profile/1001694225/daddy_daycare_/) to her first frat party. Once the boys leave to go get more party favors I ask her if she thinks any of them are cute. She mentions that a boy named "Brad" is cute. I can see how innocently she is crushing on him. So I make her aware that Brad is the President of his charter and one of the most popular guys on campus. I know my embarrassingly shy sister doesn't stand a chance to get noticed by him. I know what Brad likes because he has been with many of my friends. My sister seems eager to learn how to become Brad's perfect slut. So I start by trying to make her outfit more slutty as I notice that she not only has hot lingerie on but also a really rocking body. Brad only likes girls who are experienced so I train my little sister everything I know and make sure she will be the most popular slut on campus. I make her cum twice from licking her wet little pussy.
