Hey, I know that you're my big sister's boyfriend but I got a bit of crush on you. Is it wrong? Does that make me a naughty girl? I see how you look at me, you can't deny that I turn you on. You don't have to worry about it, I will never tell my sister about this. This is our little secret. I desperately want you to fill my pussy with a big load of cum. I'm so much younger and hotter than my sister. Promise that I won't tell anyone, I just need your big cock inside me. Fill me up with your sperm. :P
