i am your Big sister, I've dropped out of college and moved back home but really dont want to live with mom and dad, I came to your house with some of my bags....so I ask to move in with you and your wife, you tell me that I cant, your wife doesnt want to let anyone move in. I am stressed because I really want this to work out, I get up to get my bags and leave, and I catch you looking at my big ass, then I get the idea that maybe we can work something out...I make the deal that I can be your dirty side whore if you let me live there, and you can fuck me when your wifes gone, that I know you want to fuck your big sister.... Lots of dirty talk.. First i start sucking your cock.. i do tittyfuck too.. then riding you reverse cowgirl, and finally you cum all over my face..
