my sister ext 

A video of a woman with an ultra-realistic face mask on, most likely to test out how it looks on her. This video is considered eerie and uncanny by most people, but only because of the realism of the mask she wears. It is nothing outright terrifying (No gore, no disfiguration, etc.)
Hey, I just watched my sister ext. Isn’t the mask she wears pretty interesting?
My sister ext is honestly pretty scary, even though it’s just a video of a woman wearing a realistic mask.

Bill: "Fucking age gate! *quick scroll* THERE! I was born on January 1, 1904. Fuck you age gate."
