Amy moaned, tears suddenly rolling down her face as he stopped, right in the middle of one of the best possible orgasms, and she was left unfulfilled -- again.  It wasn't fair, what had she done to deserve all this frustration?<br/><br/>"Oh, please, no, don't stop," she begged, shaking almost too much to speak.  "Just a little longer, please, then -- then you can do whatever you want."  The tears fell harder now, and she shook her head.  He was like the rest, it seemed, at least a little, but it was too late now.  But he'd take pity on her again, he had to, and she looked at him desperately.
