Celia clamped her jaw shut as her nipples were pulled and twisted. The pain and pleasure were so closely intertwined that she was no longer able to distinguish between them.<em>Ohhhhhh this is so gooood it hurts so much!</em>The other part of her mind chided her<em>If you scream she'll stop doing it and probably let you go home. That's what she said she'd do to punish you. Just scream!</em><br/><br/>The stroking and scratching on her inner thigh made her foot twitch, then her knee jerked, uncontrollably.<em>Thank the gods and powers that she didn't tell me not to move too!</em>Celia managed a rational thought. from the one part of her mind that was still a dispassionate observer to her torment. And the first part, the submissive part, simply stated<em>I don't waaaaaaant... her to stooooop!</em><br/><br/>She gazed back into Mistress' cold, hard eyes, and saw the expectation of failure, saw the look that said<em>I want you to fail</em>, and at the same time, the slight softening that hoped she would not. That part... That was the part of Mistress that she had fallen in love with. The part that wanted her to pass these painful tests, and give her a reward at the end.<br/><br/>To that part of Mistress, Celia managed a smile and a slight nod. The taste of blood was in her mouth and she swallowed, thene carefully, carefully unclamped her tongue from between her teeth. That almost got a whimper where her determination would not allow anything Mistress did to produce one. She knew she would be talking funny for a while.<br/><br/>Her breath became shorter and harder and her eyes indeed dilated, the pupils grown so wide that Mistress was nothing but a silhouette with two burning eyes of her own.
