Your neighbor's daughter

As your sister says "because why waste my time with anyone but you." you notice something out of the corner of your eye. Through your bedroom window, past the 10ft gap between properties, and through the window of the house next door someone is watching what you and your sister are doing.

Though the body is far more voluptuous the face is remarkably the same, though now devoid of make up that would be unneeded now. Head of the high school cheer squad and blonde beauty even before everything seemed to change it was your neighbor. Naked as the day she was born leaning on the window frame watching you and your sister with one hand, her other reaching between her legs fingering herself.

Your sister turns her head and looks out the window, and says "Bro it seems you have another fan." as she spits on your cock the gentle strokes now replaced with furious pumping with both her delicate hands up and down the length of your monster cock.
