Your step-sister informs you that she went onto your computer the other day and found some VERY interesting videos that you had been watching. She knows all about your dirty little secret, and she will let that secret out if you don't do exactly as she says. She wants to torment your cock and balls, just like the women were doing to those men in the videos you watch. It's no secret that she's never liked you very much, so she doesn't go easy on your poor body.
