A sadistic club owner forces proud hostess Tsubaki through brutal deepthroat training so he can make her provide sexual services to clients. Cocks hammer her throat until her esophagus feels ready to burst, while inverted forced deepthroat leaves her haughty face gagging and soaked in drool. Objects are shoved into her throat and pumped purely to make her suffer, then her mouth and pussy are used at the same time in a degrading threesome. The more she cries and screams, the harder the throat-fucking becomes. Her hidden masochistic side is exposed as she sobs, gags, and gradually loses herself to cock.
