Celia groaned in frustration and pain, She tried to increase the pace and depth of Mistress' thrusts, bu thrusting up as Mistress thrust down, but Mistress anticipated her and simply held back whenever she tried it.<br/><br/>"Ooooh!" She cried out. "Oh, Mistress, please? More? Please?" She begged.<em>Oh god, listen to you. You are pathetic, you know that?</em>Celia shook her head violently, under Mistress' skirt.<em>No. No, I'm not. I love her and she loves me and this is how we express our love for each other. That is about the most pathetic thought you have ever had!</em><br/><br/>But she refused to listen to that other voice. She had seen that brief glimps on Mistress' face and she knew. She gave up trying to force Mistress into pushing the rest of the dildo into her, and tried to relax. she lifted her hand's groping blindly, and touched Mistress' hair,  following it up to her head, she began gently stroking in time with Mistress' thrusts.
