At the other end, the phone started to ring. I took only a few seconds, and then she heard a deep male voice on the other end, saying, "Hello? Lambèr... residence." Hello, Sir! It's Sandra Le-Croix. Could I speak with Frederik? Please!" Sandra asked."A moment," the man answered and then Sandra could hear him shout, "Frederik! It's for you."After a few seconds, she could hear how another phone was picked up at the other side, and then she heard Frederik's voice, "Hello?" Hey, it's Sandra!" she.

Another thought occurred. What's good for her friend is good for me. So, I slipped my cock inside my sister’s mouth and took a picture. Part of me wanted to ram it all the way down her throat.But, that could be really messy given her drunken state.I decided to roll my sister over for a couple more blackmail pictures.
