Mistress, a dominant force, takes control in a dimly lit dungeon. She commands her submissive, binding him in intricate ropes, his body taut and vulnerable. She teases him, running her fingers along his thighs, avoiding his throbbing cock. She leans in, her breath hot on his ear, "You will beg for my touch." She smirks, guiding his cock into her mouth, sucking hard, her tongue swirling. He moans, helpless, as she fucks his cock with her mouth, her hand gripping his balls roughly.
