In a dimly lit dungeon, a rotund slave, her body adorned with sweat and the marks of her master's pleasure, is presented with a challenge. A towering, veined cock stands at attention, a monument to her servitude. She approaches it reverently, her tongue darting out to lick her lips in anticipation. Her ample bosom heaves as she takes the first tentative lick, the salty taste of precum exploding on her tongue. She moans, her eyes rolling back in her head, as she takes the head of the cock into her mouth, her lips stretching to accommodate its size. She works her way down, inch by inch, her mouth a warm, wet haven for the throbbing flesh, her hands caressing the master's thighs in a silent plea for more.
