Your bratty big sister, Janira just came home from college for the summer, now the two of you are finally alone. Janira and you developed a special relationship ever since she found out about your diaper fetish is "Is My Brother Wearing A Diaper!?" You've missed the way she relentlessly humiliates you, while obviously accepting you for who you are. From talking to your sister while she was away, it seems as though she's become even more open, as she simultaneously developed her own fetish for humiliating little freaks like you. You've been so looking forward to having her home, but you never dreamed the first night back with your sister would be so....perfect.... That not only would your sister encourage you to cum in your diaper... but that SHE would put on a diaper, too, just to enhance your experience!
