A treat?  She heard the Head say a treat if she made Yvette cum.  she wasnt sure how, but she knew she wanted a treat.  Her own body was so hot, writhing on her face as she lapped and sucked her expertly.  She felt a finger at her bottom and she groaned, it felt weird.  But not unpleasant.<br/><br/>Wondering what she could do she slipped a finger into Yvette, it felt all warm and wet, soft and bumpy at the same time.  She wriggled it about and them moved it in and out.  She added a second, and then sucked hard on her clit, continuing to finger her as she sucked and teased her clit.  She was quite getting into this.<br/><br/>She loved the Headmaster's touch, the kisses, his caresses, it all added to her own arousal, her own building orgasm...
