There's something especially cool about watching private SM scenes filmed by real couples – especially when they are into serious pain.
Simply piercing his slave's cunt is not enough for slavegirl tri's master. The needle drives directly into her clit hood, which he inflates to enormous size with an agonising saline injection. The needle then pushes straight through he hood to re-enter her poor swollen cunt just below her clit, inflating there too to completely bury her clit in the raw stretched meat.
This is a private amateur scene of genuine SM action between a real slave and her Master. He operates the camera himself, and pans to her face to show her screams and pain as he seals her clit in swollen flesh.
