Andrew, at 18, was in his first year of college. He was a nerd, a geek, and usually pretty shy. He was still a virgin too and had had nothing more then a handjob before. While he had the brains in his family, his younger sister had the l ooks. She was the
head cheerleader in the highschool and quite popular, other girls wawnting to be her and be with her. Boys too. And she was quite the tease.
Home for break from college, Andrew couldn't keep his eyes from her in her bathrobe.She teased him, said dirty things to him, and then grabbed his cock. She let him suck her breasts too. Later that evening, she took him to a party - a party he never went to in higschool - where she revealed herself to be the mistress of a feww other girls. She even made him show them his cock before making one of the girls give him his first blowjob - as another girl ate her out!
But Andrew knew something. Her dominant demeanor was just her being a bully. He knew it all to well. So later that weekend when the family had movie night, he fingered her and made her give him a handjob, starting to take the reigns from her. In the morning, once their parents had left for church, he woke her up by tying her to the bed, making her openly admit that she wanted to fuck him and be his slave. Andrew was more then happy to make his sister his pet and slave, excercising his new, dominant self.
