Master Frederick puts a neck strap around Dawni Violin's throat and strips her naked, fingering her clit as she fights for air. He then brings her to her knees so he can feed her his cock before putting a muzzle on her to keep her quiet. His arm snakes around Dawni's throat... He squeezes... She goes completely out. When she comes to, he bends her over a counter and fucks her, not stopping until he fills Dawni's hole with his cum.
