.Finally!!I will admit, at this point, I was already turned on just by thinking of taking her for the first time.I was sat up at the end of my bed whi...e she lay there, wearing one of my t-shirts and a pair of baggy shorts that shown her lace panties as the shorts were pretty big and didn't cover her properly, obviously, I don't let on to this fact as I was enjoying the view.The night slowly went on and at this point, it was around 1 AM. My party was still going strong and my family were still. "Cindy was not pleased when I showed up at the house and told her she had some choices to make. I'm pretty sure that she had been looking forward to 120 days (minus time off for good behavior) of unrestrained unfaithfulness so it came as a small shock to her to find out that I was going to be her babysitter. I told her what Donny had asked of me and then I spelled it out for her. "You can either move in with me or I'll move in with you. Your only other option is to pack your bags and leave. I thanked her.Mistress felt in her handbag and produced, what looked to me like a TV remote. "It's an electric dog collar" She explained, "It has 3 different settings."With this, she pressed a button on the remote, I felt a surge of electricity run through me, I would describe the feeling as unpleasant rather than painful."That's setting 1," she explained, "I'm going to use this instead of the bell, every time you feel this, you will immediately stop what you are doing and come to me. Do you. Before I could blow my load all over my hand I hear a voice from behind me. ‘Oh my god. Jack what are you doing’. It was jess. She was standing in her wet bikini. Her arms were crossed and her eyes nearly in tears as she realised what I had done. How could I have been so stupid not to check if she was in the pool. ‘How could you jack? You’re sick. You’re my bloody twin brother for Christ sake. I’m going to tell mum and dad’ ‘No you’re fucking not. Sit the fuck down’ I said. I jumped up off her.
