Christy knelt on the floor, eyes lowered respectfully as she waited to be summoned by her mistress. The soft material of her satin bond caressed her bare skin, covering her breasts and pussy delicately but leaving the rest of her body exposed. Christy heart raced with anticipation, knowing that today was a special day - her mistress' 18th birthday. As she heard footsteps approaching from behind, she took a deep breath and steeled herself for whatever delightful torments or pleasures lay in store.
