"Now get fucking moving."As she crawled slowly to the security entrance into her block of flats I looked inside her bag and found what looked to be th... right keys. When I unlocked it she crawled slowly on her hands and knees up the one flight of stairs to her front door without meeting anyone on the way. "That's the girl, you know if you keep behaving yourself I might not have to hurt you too much."As soon as we were inside she led me to the lounge, indicated a comfortable looking leather couch. Worse, there was a man. Although it helped somewhat ... a little anyway ... that he too was naked in a prisoner rack, wearing a collar and nothing else. Calling him a ‘man’ might have been generous, he couldn’t have been eighteen yet. He wasn’t even seated, he had been left against the wall. There were also five women, two in racks, three not. All five were seated, facing the naked slave, none of us women wore a collar. His cock was standing stiff, The one woman sitting alone was dressed much. I figured I'd run a 1-minute 20-second 400. How about that! But could I maintain this pace through 10,000 meters? With a little extra effort, I thought I could break the 15-minute mark for the 5K, but... There was only one way to know. I ran, picking up my pace a little.I'd told Jenny girl that she didn't hold me back while she ran with me, but she did, not much but a little, and I did increase my pace after she dropped off, mostly to take myself close to failure as soon as possible, failure. Spreading her ass and squeezing it. I stood up, and told her not to move, as I went into the bedroom grabbed a pillow and some lube. Not that she needed any, because I could smell how wet and horny she was. I came back in and she noticed how hard I was, but I wouldn’t let her touch me. This was about her, not me. I had her raise her ass up and I slide the pillow under her stomach. Now her ass was up in the air a bit. It was a beautiful sight to see. I straddled her again and started working on.
