On how to wake up and when to cum

Miss Lexter pulled a small box out from under the table and said "As part of your job, you will need to be available constantly. Therefore, I would like you to keep this on you on all times.", as she pulled out a small pink plastic egg, with a string attatched to one end. "This device will vibrate for five minutes every morning in order to wake you up. Your first duty when waking up is to hurry over to my room and taking care of my morning wood. Furthermore, I will call you using this. When you feel the vibration through out the day, it means that you are supposed to come to the living room. Did you get all of that?" she asked, to which Sophie responded "Yes, misstres." Miss Lexter smiled and gave the vibro-egg to Sophie, who then had to insert it into herself, while miss Lexter was looking.

"Very well done my dear. The next rule you will have to follow, is that you may only ever cum when I allow it. You will beg me for release, and I will deny it to you for days, and even weeks. Now keep still..." miss Lexter said in a sultry voice. She got on her knees and put a chastity cage on Sophies member. The ring sat tightly around her cock and balls, leaving not even the slightest bit of wigle room. The cage, made from thin steel bars, was so tiny that even Sophie's moddest dick was squished together into less than half an inch. Sophie winced as miss Lexter put the device onto her, but didn't struggle. "Now my dear, you will be allowed your next orgasm when you are able to take my entire shaft down your throat, to the base." she said."If you want to try your luck, you can allways ask me." she added with a wink.

With that, Sophie was dismissed for the evening. She went upstairs into her room in order to contemplate her situation. No matter how she pulled and tugged, the cage tit not loosen up the slightest bit. It had allready been two days since she had masturbated, but even though she was very pent up allready, she had to go to sleep frustrated.
