Get herself off in front of Him.... and his camera!

Without another word He got up and walked over to His bag. She didn't dare to raise her head to look what He was doing; she was still busy being scared anyway... Could she humiliate herself like that, make herself cum in front of His very eyes? She was so overwhelmed by her own fear and excitement that she hadn't heard Him walk back over to the sofa. "Look at me," He demanded. She raised her head and couldn't believe it. She was looking straight into a video camera, the red light flashing. A look of panic appeared in her face. This was too much. Not on camera... Who knows where the tape could end up?! "Sir,..." she started to say when he interrupted. "What are You?" he asked. The whole situation became too much for her. Aware of the embarassing picture she was providing she suddenly felt completely powerless, completely under His spell and at His mercy. Not being able to resist anymore she answered "I am Your **** slut, Sir, existing just to please and entertain You, Master." "Good, slut, go on then... entertain me!" he demanded with a smile on His face.
She wasn't anything anymore but His ****, His property, there to please Him. In that moment all her inhibitions and shame fell from her and her hands started to move over her body. Over her breasts, at first,... her fingertips teasing her nipples which had become hard a long time ago. She suddenly felt so aroused, horny like never before. Her fingers just had to dive down between her spread legs. Stroking her own pussy lips, back and forth, her fingers parting the lips, sliding inside herself. With her other hand she kept playing with her nipples. Her right hand was fucking herself as her left hand was sliding down in between her legs as well. Her left index finger started rubbing her clit, while her other hand was still fucking her cunt all the time. "MMmm..... aahhhh," moan after moan came from her lips. Her eyes sometimes closed, sometimes looking straight at Him and the camera. Mmm.., she couldn't take it anymore... "Sir, may i come?? Please, PLEASE," she screamed and moaned at the same time. "No, slut, no cumming yet," he ordered. "Pleeeaase,,,,, please, Sir, please,..." she begged. What a sight she made! Kneeling at Her Master's feet, fucking herself like a slut and begging to be allowed to make herself cum! And all that in front of a camera! "Mmm... please, Master, please," she kept screaming. "No!" was His only reply. She heard Him but couldn't take it anymore, she tried hard not to cum and displease Him but it was too much, she finally gave in. Her body spasmed into wave after wave of one of the most intense orgasms of her life. "Aahh..mmmm" she was moaning and gyrating her hips... After what seemed like an eternity she finally seemed to come back to her senses and realized what she had just done. This must have been the worst mistake she could have made. Cumming without permission! She lowered her head, afraid of His reaction but even more upset about disappointing Him so much. "I'm sorry, Sir,.. I didn't mean to.. Sir, please forgive me,....." she stuttered.
Putting the camera down he said "I am very disappointed in you, **** slut. Is this what I taught you??!!" Tears of disappointment and sadness at having displeased Him started to form in her eyes.
"You are aware of the fact that I cannot tolerate such behaviour, slut?" "Yes, Sir," she whispered, her head still lowered, not daring to move a muscle.
With one swift movement he pulled His belt off his trousers. "Get over there and lean over," he ordered, pointing to her desk.
