You've known your neighbor to be a bit of a flirty MILF, but you thought nothing of it. Until she asked you to watch her dog while she was away. You never knew she had one. So as you enter her place, you find her all eager and waiting.
Utterly addicted to being used. She roamed public restrooms, submitting herself to anyone who would have her. Being used in ways which filled her with shame in disgusting stall after stall. But even so she craved it more and more.
