you know, I was gona try to top the above image by grabbing some shots of female circumcism in progress off google images. But I didn't cuz 1) Yikes! Holy Shit thats gota hurt and 2) 90% were very well underage images. But it woulda topped the above image easy.
Kudos to you for not posting it - it's also totally inhumane 99% of the time unless you found someone willing to undergo the surgery as an adult, not a child where it is forced upon them.
As for the rest of this thread - I'll leave you to it. I've seen some seriously outrageous porn niche sites thanks to a TGP and a husband who feels compelled to share. "Honey! Come look at this f'cked up shit!"
I'll let you find them on your own if you're so inclined.
