Bizarre BDSM scene with a bound and gagged slave

In this bizarre BDSM scene, a bound and gagged slave is at the mercy of their dominant partner. The slave is completely naked, save for a collar around their neck. Their hands are bound behind their back, and their mouth is gagged with a ball gag. The dominant partner is dressed in leather and has a dildo in hand, ready to use on their submissive partner. The scene is rough and kinky, with the dominant partner using the dildo to penetrate the slave's mouth and throat. The slave moans and writhes in pleasure and pain as the dominant continues to use the dildro to tease and torment them. The scene ends with the dominant finally unbinding the slave and releasing them from their gag. However, the dominant is not satisfied and continues to use their dominant power to pleasure themselves and their submissives.
