Michelle touched her shoulder gently.  "Tracy, David is right. If I didn't think it was right, didn't want to or David didn't want to we wouldn't have let it get that far.  I enjoyed it and would like to try it again with you.  It is perfectly normal to seek pleasure and maybe I can help you pleasure yourself and teach you how to please us.  Say you will?"  Her eyes were imploring, full of genuine kindness for the girl.
