I thought about someone knocking on the door and getting no answer, then trying the doorknob that Jack had forgotten to lock, coming in and opening th... door to our bedroom. How I would look from the doorway, my skirt pulled up as far as it would go, my shirt tucked into it, my panties around my knees and me leaning over, my butt pushed back, totally exposed. I could feel my pussy opening up, begging to be filled, glistening with its own moisture. The thought of it made me feel even hotter.

Mary's only response was to wiggle her ass on the bed and lift her cunt to meet his next thrust as she clamped her legs even tighter around her brother's ass so he couldn't pull away from.
