Jennifers heart was still pounding hard when Yvette released her clit, but it did not make her feel better this breif respite, for she knew that worse was coming.  This aphrodin, whatever it was, had her scared, it was an unknown quantity, and she had absolutely no idea what it would do to her.  All she could really hope to do was steel herself for the next onslaught, not an easy thing to do with Yvette nibbling her inner thight, but she didn't want to give them the satisfaction of making her scream.
