You're always being such a perv to your step sis because she’s so hot. One day she comes to you because needs help with her homework. You can’t stop staring at her tits. She’s angry because you can’t focus. She teases you and you get hard. She’s grossed out and annoyed. She makes you show her your dick. She laughs at how tiny it is. She takes pictures of your dick. She tells you that she didn’t really need help. She only did all of this to get you to not perv on her anymore. She tells you that if you want the pictures to not be sent or posted anywhere you’ll have to stop being such a perverted idiot.
