I felt the inside of her rectum, soft and warm, sucking at my finger as she fucked me. The pulsing presence of my penis sliding in and out on the othe... side of the flesh wall between her ass and her vagina, massaging her inside from both directions. It seemed to spur her on to drive into me even harder.I ravaged her neck with my mouth. She reared back to let me, exposing her breasts to the steamy air in the car. Kissing down her chest I devoured one nipple. Her weight shifted backwards against. I still had control, but I could feel that I was ready to cum anytime. She laughed at me, "You are pathetic. I will make you a good pet. Slow down, but keep stroking. You are not allowed to cum within the next 20min."I slowed down a lot to give myself the chance to last that long. I could feel more and more cum builing up and being ready to squirt out. I planned to calm a little and get super close again after 18min, so that I would be ready to cum for my mistress. When the time was over she. And that would not make my existance here any easier...even in the smallest way.We arrived at the meeting hall and sure enough, all of the slaves stood in a large circle waiting for whatever might transpire. There was a cord hanging in the center of the room with a circular fastener at the end...and I was taken there and forced to my knees beneath the dangling length of nylon.Within moments the Madam made her entrance...an arrogant and beautiful figure of a woman. Her skin tight black. But most of all, I was turned on. Turned on that much that my cock ached. I didn't remember doing it but I had my cock out and was wanking myself furiously.I noticed that people were watching me, so I went and sat in an armchair in a corner where I could watch the door. My towel was loose and my aching cock welcomed my warm hand shuffling on it as I stared intently. It seemed like an eternity. Eventually the door opened and the 3 guy's came out.I rushed over to the room and as I passed the guys.
