She said her oral sex skillz were the best in the world...Even if she did have braces on her teeth.

She went down on me and, truth be told, it was heavenly.
For a while, anyway... Until the retaining wire in her braces broke.

She didn't realize it...*I* didn't realize it...at first.
She actually went up...down...up again before I realized something had gone horribly wrong.
I pulled out of her mouth to find a bloody "Z" carved into my pride 'n joy. "The Mark of Zorro".

I guess I should be thankful it didn't leave a scar.

Tell us your story of when things went bad quickly....
