Good Boy, kneeling before his mistress, is ordered to pleasure himself until he cums. She watches, her heels digging into his back, as he tentatively strokes his hard cock. With a trembling hand, he catches the first spurt of cum in his mouth, gagging slightly. She slaps his face, "Swallow it all, you filthy slut!" He gulps, trying to keep up as she forces him to jack off faster, his cock spitting cum all over his face and chest. Finally, she allows him to lick it off his skin, savoring the taste of his own shame.
