"I--I'm sorry," Teri said, looking down at the ground as she moved to Sarah.  "I just don't want her to--to be upset.  She's my teacher."  Walking past the demon, she patted him on his hand, as if to mollify him.  "But if you want me to, of course--of course I'll do it."  She reached Sarah, and then began unbuttoning the front of her teacher's robe.  "Sorry," she told her mentor, "but I--I don't really have a choice."  She thought Sarah gave her a hostile look, but she couldn't be sure.<br/><br/>Sarah was older, but still only middle-aged.  And she had quite a bit more of a chest than her student.  As the demon saw when Teri had the robe open.  Sarah was wearing a bra, which held back full, bulbous breasts.  She was also wearing silk panties.  Teri edged the robe back off across her shoulders.  Teri looked at the demon.  "Is--is that enough for you to have a look at her?"
