She told me that she and David had been for their run, then he had given her the lower back massage he had promised. I asked more about this and she j...st said it was good, really helped her back pain. I joked and said how was it having a young man's hand on your body and she just laughed it off - but noticeably blushed.That evening we had amazing sex and I noticed she seemed to be extremely horny - in fact, she came really quickly and screamed loudly. Skip forward to the middle of the following. Any way my mum and dad decided they was going away for a week me and my sister Debbie would be left home on our own, this didn't really bother us much as she had loads of stuff to do and i just did my normal thing.Debbie said she was gonna have a couple of friends over at some point in the week and here's where it starts.It was Wednesday night and Debbie comes home with two of her mates from collage, she introduces me to them, Beth, she was shorter than Debbie by a little bit had blue eyes. He smirks. I do as he says and bend over his desk, showing my tight wet pussy to him as he gets behind me. He starts with his fingers, probing my vagina an inch at a time with one finger, then slowly adding a second as he finger fucks me. I wasnt expecting to enjoy it so much, but with each thrust he makes I get even more wet. I dont even see his cock before I feel the head of it rubbing up and down against my entrance. As far as I can tell its thick, thicker than anything Ive ever had before.. One day, as usual I went to him and I found his front door closed. In our area, our houses are villa type and not like flats, as in northern states. I walked to the back door. As I was walking through the side of the home, I heard a murmur sound and I looked up and noticed that it is coming from their master bedroom and the window is slightly open. I peeped in and I am stunned to see the scene inside the room. Two bodies are moving violently. Firstly, I couldn’t understand what they are doing.
