Thanks everyone for your ratings and feedback, so long as enough people enjoy it I will continue the story. This is a continuation of part 1.
****************
The next morning I woke up early and ready for another lesson with my new slut. Around 10am I phoned her mobile and after about 10 rings she finally answered.
"Hello," she said almost whispering as if fearing my reason for calling.
"Hey slut, just finished watching a rerun of yesterdays fun!" I left a pause for all the memories of yesterday flood back to her before continuing, "Can't believe you drank all that cum! Don't worry babe I'll share that tasty load with your other holes today!"
There was no response except I could hear her breathing getting quicker so I continued. "You best not be rude to me now slut, I gave you a compliment I expect a thank you."
After a pause of another few seconds she replied softly as if on the verge of crying, "Y, yes. Sorry. Thank you."
"Master!" I corrected her.
"Thank you master," she finally brought herself to say. Although I thought I could sense some repressed pleasure she felt when saying those words.
"Good girl, now I'll be round in about 20 minutes," I said in a mock caring tone.
"No. Please. I'm not ready yet. My mouth still tastes of you and my parents will be home. Give me a few days." She was getting desperate towards the end of that sentence, "Please master." She thought the 'master' part would sway me but she would have no such luck today.
I raised my voice, "Slut! When I say I'm coming round in 20 minutes it means exactly that, it's not a discussion it is an order." I heard her sniffle on the other end of the phone and softened my voice, "Right, now that that's sorted make sure you don't wear any underwear when you greet me today, it just gets in the way. And by the way make sure your top is thin and don't say a work unless I ask you a question. See you soon." Before she could respond I ended the call and started to get ready.
I left her waiting at least 40 minutes before I finally arrived and rang the doorbell. She opened the door instantly as if she had been patiently waiting there for me for a very long time as I hoped. As she opened it I was already hard, my sluts nipples could easily be seen through her thin t-shirt. She obviously knew this too and tried to hide them with her arms but I quickly slapped her arms away and had a quick grope. Already her face was as red as beetroot while I groped her in full view of her neighbors. At least she had learnt not to try and pull away I thought. Her pert nipples felt great in my fingers and each time I pinched them she screwed up her face but said nothing.
