Lin's cheeks glowed bright red as he said what he taught.  She gulped and dropped her gaze, already they were into the special subjects.  She had already done some oral, that was what she had done with them.  She felt a wave of regret when she thought of the former Heads. She wondered if she was still entitled to the collar she wore.  She sat as he had said, legs together, back straight.<br/><br/>"I..I erm..I have had oral." She stuttered, "anal? I have only had fingers in me...there" she blushed deeper.  "Group?  I don't know, I have been with two people, but I have never thought about it all.  This is so new, I was a virgin yesterday" she told him, tilting her head, "I think maybe Anal would be good to learn Sir" she said softly, giving him a shy smile.
