My little sister has been sneaking into my room without permission, using my PC or watching erotic DVDs and magazines while masturbating alone. Although I knew about her activities, I had been tolerating them. However, I can't take it anymore. I decide to give her some real dick action by showing her how it's done during one of her private sessions. When I enter the room and ask what she's doing, she stammers out something like, "My friend told me about having sex with her boyfriend... so I was curious..." This gives me the perfect opportunity for some unplanned sexual education...
