Your stepsister Hannah is calling you to her room, she wants to talk to you. You can use a dildo if you want, but it is optional, so are the kneeling + gag, do if you want to. Rather short tease.
You have always fantasised and dreamed about her, could this be your lucky day ? A fairly small teasing part after a story introduction. The hornier you are coming to this tease, the better.
