I need to stop by your place. My sis has requested I go to pick up a few thing's and seeing as you and her are to be married tomorrow its bad luck for you to see her. Being the kind step-sister I am, I step in.  I ask you to show me where her things are then we start talking. The conversation turns a little naughty and I cant help but quiz you about your coming up marriage. You know once you're married you can't fuck other people? are you sure you're ready for such a big commitment.. Sure you don't wanna fool around one last time ? Why not do it with me.. I know you've always had a thing for me. Why do taken guys turn me on so much? I fall to my knees and suck your cock .. Fuck im so wet and horny .. I need that cock inside me.. let's just fool around one time before you marry my step-sister..Please..fuck me
