Celia nodded and climbed down of Mistress' desk. "Yes Mistress." As Mistress left the office, she gathered up her clothes from a chair where they were neatly folded and put them back on. She wore a tartan skirt that came to just above her knees and a white blouse that she buttoned securely over her ample bosom, then slipped on her dark grey blazer.<br/><br/>She quickly made her way to the staff lounge, and poked her head in, "New students are arriving in ten minutes". She announced, regardless of anyone being in there, then went up the steps to the staff's private rooms. She checked each room in turn, tapping on closed doors and making the same announcement. Finally, she headed down to the main entrance herself, fully aware that she smelled ever so slightly of interrupted sex.<br/><br/>Her pussy ached for the orgasm Mistress had denied her. She hoped her new student would be with the first batch to arrive.
