Hypnotic butts

I was baffled at the second I saw this gif. How long exactly is that torso and why can she bend it like that? Also, the longer I look at that short, the more it seems to be aa sentient being, trying to struggle free.

This is so hypnotic... maybe this is how snakewomen hypnotize you...
