They were best friends for life. 

    Best friends forever. Best friends and only friends despite her knowing that he had a really big crush on her for years. Despite her knowing he would do almost anything to be more than just friends. 

    But they would always be best friends no matter what So she simply accepted it as a nice friendly gesture when her best friend confessed he had been fantasizing about orgasm denial for months now and had been experimenting with locking himself in chastity for a few weeks and wanted her to hold onto the key.

     She understood he needed a keyholder if he wanted to go through with this due to his lack of self control. She wanted to be a good friend and help him out. 

    Plus, it might be kinda fun!

    But she had no idea how quickly their relationship would change as soon as her friend handed over the only key.

    Within 6 weeks she had her best friend doing her homework, doing her chores, and even licking his own Bullies cum out of her loose sloppy pussy after she ditched her friend to spend hours getting laid, which ended in multiple creampies from his Bully.

    And through all the denial and torture and humiliation she put her best friend though, he never once asked for his chastity key back. He just kept begging her for more. More teasing, more humiliation, more creampies, more cuckolding with his Bullies, more being used...more of everything except orgasms - something he hadn't had once since she had taken control of his manhood.
