The next day I woke up with a smile on my face. I had just had a wonderful dream, I dreamt of a time when she finally submitted to me and became my personal fully trained cock slut. A time when I wouldn't have to deal with her resistance or despair about the situation, only thinking about giving me pleasure with all her holes. Although I can't deny that her resistance turned me on. With a raging hard on I rolled over and picked up my phone before dialling her number.
It rang a few times and for a moment I thought she wouldn't pick up but soon enough it crackled and her timid voice tentatively came through, "Hello..."
"Hi slut!" I boomed happily. "What are you up to? Who are you with?"
She replied with her voice barely distinguishable as she whispered, "Just... just my friends, were eating lunch at a restaurant."
"Oi, you'll call me master when I take the time to call you!" I shot back, already her resistance today was grating on me.
"Please, not here," she whispered back.
Now I was beginning to get frustrated, "Slut! This is permanent. Not just something that you can turn on and off!"
"Sorry.... Master," she whispered as quietly as possible, as she said this I could hear talking in the background.
"Louder slut! Haven't you learnt anything yet! I guess I'll have to remind you how you should speak to your superiors later on."
Finally she spoke in a normal tone, "Yes master." As she said this I could hear people in the background murmuring and laughing.
"That's better. I'll be over in 10 minutes. Be at your front door or else," I said, my horny feeling increasing at her humiliation.
"No no please, I can't keep doing this," I could hear her blushing through the phone.
"That wasn't a question slut. I'll be there in 10 minutes, you better be too." As I said this I gently stroked my bulging manhood through my boxers, my cock knew that it would be impaled in her tight body very soon.
"I.. I'm sorry but I have something booked in an hour. It was very expensive." she said trying to sound authoritarian. "It's er, it's a spa day to make me feel better about myself. To.... to try and forget what we've done recently..." I could hear tears in her eyes when she said this.
I began to laugh, "Fucking hell slut. When will you learn. When I say we are meeting that's it. I'll send all the pictures I've taken to your friends and parents if you don't and you know that will ruin your life."
Now her voice was dejected, "But I've... er... been saving for weeks for this and I can't get my money back."
