"Awww...really close? Really, really close?" Alecto cooed teasingly. She kept up her attention to Spencer's clit making sure she got even closer. That was, before she stopped all together.
"Yes, Miss Fawcett?" she asked when Spencer pouted at her. "Did I say that you could come for me?" She grinned. "Maybe you should seek my permission before you come? Don't you think that would be appropriate?"
Leaning in, she began to lick and suck once more in earnest. This time, she made sure to apply enough pressure, and keep up an even pace, to push Spencer to orgasm. That was, if she didn't fight it.
