In the dimly lit dungeon, Mistress bound her slave's wrists overhead, leaving her legs free. The slave's pussy glistened with anticipation. Madame, dressed in leather, commanded, "Spread." The slave obeyed, revealing her wet, pink core. Madame leaned in, her long, red nails glinting as she slowly inserted two fingers into the slave's tight, warm pussy. She pumped, twisting her wrist, hitting the slave's G-spot. The slave moaned, her body writhing. Madame added a third finger, stretching her slave's pussy. She fucked her roughly, the sound of wet flesh slapping filling the room. The slave's legs trembled, her orgasm building. Madame ordered, "Come," and the slave exploded, her pussy contracting around Madame's fingers.
