In a private dungeon, a submissive is transformed into a helpless frog, bound and gagged, at the mercy of his dominant master. The master, a sadistic connoisseur of kink, delights in the sub's futile struggles as he humiliates him, using him as a piece of furniture, a human ashtray, and a sexual plaything. The sub's body is pushed to its limits, as the master's rough, demanding touch and cruel words push him towards ecstasy and shame in equal measure.
