Sandra, collared and bound, is Frank's canvas for discipline. He paints her body with stripes from the whip, her cries of pain morphing into moans of pleasure. He commands her to beg for the wand, her humiliation palpable yet arousing. Frank obliges, the wand's relentless vibrations driving Sandra to the edge. He denies her orgasm, switching between pleasure and pain until she's a sobbing, begging mess. Frank, his cock hard from her suffering, decides it's time for her to truly understand her place. He uncuffs her, positions her on her knees, and feeds her his cock, claiming her fully as his submissive.
