From an early age she was forced to perform oral sex on man after man after man.
She was determined to get revenge, and thus invented the 'Anti forced oral sex machine'. It had a boner deflecting screen which was it's most ingenious feature.'
Although she had been forced to suck hundreds of dirty boners in her early years, (and did suffer some minor adverse effects), she actually came to enjoy the attention of the type of men who routinely force girls to perform fellatio on them.
Her problem was that she was too proud to admit it, which led to her inventing that machine.
Now all the neighbors boners and things will nevermore be clean, they've all become monuments to smegma, because of that machine.
For her complete story, google her name... 'Jonni Verbek'.
