In the dimly lit dungeon, a bound slave, her muff exposed and vulnerable, awaits her mistress. Rough ropes dig into her soft flesh, restricting her movements. Her body is a canvas of crisscrossed marks from the previous session, a testament to her mistress's skilled touch. The air is thick with anticipation as the mistress enters, her eyes gleaming with sadistic delight. She runs her hands over the slave's body, tracing the curves, making the slave squirm in her bonds. The mistress's fingers find the slave's muff, already wet with anticipation, and she begins to stretch it, preparing it for the toys she has in mind.
