"Am I a whore then?" she cried."Oh yes you are," he replied in a deep grunting voice, "You're just a cheap slut who fucks for money!" Yes I am aren't ...?" she shouted. "Then fuck me like the slut I am. Go on, deeper, harder. You've paid for it haven't you?" Oh I'm getting my money’s worth you dirty whore," he growled in reply.The aroma and atmosphere in the room was incredible and I couldn't believe I was finding her behaviour so arousing. My own cock was now hurting it was so hard and it. He saw Alex lick her lips a few times as another contented smile formed on her beautiful face.Justin slowly retreated from the bed, watching Alex to be certain she remained asleep. Once he was off the bed, Alex turned over on to her stomach which gave Justin his first real look at her glorious ass. Sure, he had looked at her ass plenty of times, but that was when she had her clothes on. He always thought she had a nice butt 'for a sister', but had never dwelled on it beyond that. He now stood. I asked how she planned to spend her day in London, she replied buying books in the morning then seeing the sights. When we took out books to the counter I insisted on paying for hers and we wandered off out into the sunshine. I took her on a tour of the sights of central London, and she enjoyed it. I have a little one bedroom flat in central London, which I use when on business. I suggested to her that it was hot and we could go to my place to cool off and read the books. She seemed in no. It wasn't until I saw an early 'porn' video in a bookshop for the first time and didn't really know what was going on, but now I know was a couple having intercourse. The woman serving in the shop laughed out loud when I asked Her, as I was paying for the stash of dirty books I was buying - "what's that film all about, what's happening, why is that woman in pain, why is he doing that to Her, it sounds like he's hurting Her, what sort of film is that?" Guess that sort of gave the game away to.
