Watching My Stepsister Sunbathe

During a trip to the ranch I caught my step sister sunbathing and I could not stop staring. It has been so long since my wife has drained my balls and that pink bikini got my cock rock hard. I figured no one else is here right now why not release the pressure. While stroking my cock I look down for a second and when I look back up Jane is gone. To my surprise she saw me through the window and came inside to catch me. Calling me all kinds of names asking if I thought she couldnt see me. I stop her and tell her my balls are backed up. I can't help it. Then Jane thinks about some of the stuff we used to secretly do back in the day and her pussy gets wet. Jane starts sucking my cock and we start fucking it doesnt take long for my cock to explode inside her pussy.
