As I followed Mistress Xaviera to her bedroom, I once again marveled at her perfect form, from the clear high heel mules on her perfect feet, to the feminine shape enclosed in the skin tight black leather miniskirt/dress. My Mistress had a remarkable way of walking, almost like she was gliding over the carpet, displaying such sensuous grace I had seen only in the movies. As I walked I kept trying to stretch my fingers but they were still numb and unresponsive from the devotion Mistress had me perform. However, when we started up the stairs I realized it was all worth it. I got a chance to follow my Mistress and was rewarded with a wonderful view up her shapely legs and a glimpse of white panties. Even better was the sight of her clear heels walking up each step in front of me. Each time her foot raised up from the lower step I got a clear look at the bottom of her lovely heel and then her foot as it lifted off the mule and proceeded to the step above. I barely refrained from placing my hand under her heel as it settled on the higher step for fear that it would displease her…and that was the last thing I wanted to do.

I followed Mistress Xaviera into her bedroom. She showed me around her room pointing out things I needed to know. I saw her closet where she keeps at least 100 pairs of shoes, mostly high heels of all kinds. She reminded me that my job was to make sure each shoe was kept with a polished spit-shined gloss. She showed me her bathroom and explained how she wanted me to position myself when she took a shower. Then I followed her back into her bedroom where I heard her plans for the day.

"I usually start each Saturday with a 30 minute aerobics step workout, then I take a long hot shower. Today I am having guests over for lunch…I think my friends will enjoy having you underfoot. Tonight I am going to a birthday party for one of my friends…you are also invited."

I could hear the mirth in her voice as if she was sharing some private joke. It was enough to cause warning bells to sound in my head.

"But first, I need to do my aerobics workout for today. Since my other step 'broke' you will have as one of your duties the honor of being my step from now on. Take off your clothes and lie on your back in front of the TV. I don't want you to move for the duration of the exercise. Do I make myself clear?"

"Yes, Mistress," I answered weakly. I was beginning to wonder if I had really made a mistake in underestimating what it would be like to be a full-time footslave. Although I had been successful a coaxing a few of my female friends to stand and walk around on me, I had never had anyone jump or run on me. I wondered if my poor 5 foot 10 inch 170 lb body could withstand that kind of treatment. However, I quickly removed my clothes and laid down on my back in front of the TV as I was instructed, and waited for my mistress to begin her aerobics. She emerged from the bathroom wearing a loose fitting T-shirt and biking shorts, and white ankle socks encased in an expensive pair of aerobic workout shoes. My heart began to race as I glimpsed the bottom of those workout shoes. I began to realize that I would get a very close up and personal view of the strange looking tread on the bottom of her shoes.

Mistress Xaviera walked to the TV and started a tape already in the VCR. Within moments the VCR announced the 30 minute high energy aerobics step workout with some famous celebrity instructor. My Mistress positioned herself at my right side facing the TV and began to loosen up with the instructor. After several minutes of stretching she began to march in place right next to my chest. As I gazed up at Mistress Xaviera I realized that I was hopelessly enthralled with every part of her. From her beautifully sculptured face to the perfect curves of her body to the shapely but powerful legs to the feet encased in the workout shoes. She was so beautiful that I lost track of what was happening. I was totally unprepared when she stepped up on my chest with her left foot, then brought her right foot up beside her left foot. Her left foot crashed down in the middle of my chest, knocking the wind out of me, and quickly brought me back to reality. Her right foot crashed down on my stomach and felt like the shoe touched the floor beneath me. Although she quickly stepped back down to the floor, I was already gasping for air and trying to recover from her first step. She quickly followed again and again and I found I could not catch my breath. Each time she would step up on me it would force the little bit of air I had managed to get out of my lungs. However, I began to catch hold of the rhythm of her step and was able to get little breaths whenever she stepped down. I also quickly learned to tighten my chest and stomach muscles before she stepped up. I was now beginning to enjoy the experience of being her human step. It was wonderful watching her calf muscles flex as she lifted her legs and stepped up on my chest and stomach.

As she increased her workout she began to bounce a little as she stepped up, making it harder for me to keep my breath. Foolishly, I began to think that being her step wasn't really that bad. Before that thought was complete, the instructor changed to a wide-legged step. This time my Mistress brought her left foot up and placed it directly on my throat. As her weight increased I thought my throat was going to be crushed. All air was cut off as her left foot supported all of her weight on my throat as she brought her right foot up, right on my cock. In spite of the pain of her weight on my throat, the pleasure caused by her right foot as it crushed my cock caused my eyes to roll back in my head. She continued to step on my throat and cock for several more minutes. I was no longer paying any attention to the instructor on the videocassette; I was totally absorbed in what my Mistress was doing to my cock. Then without warning, she jumped with both feet onto my ribcage, crushing the air out of me. Then she jumped back down. The next jump with both feet landed on my stomach, making me almost double up in pain. The next jump landed on my cock with her left foot, but unfortunately for me her right foot landed on my balls. Pain shot through my brain, and I really wanted to pass out, but my body wouldn't cooperate.

Through stars I saw (and felt) her begin jumping up my body…my stomach again, then my chest. I watched her jump down from my chest, and bounce a little to her left. Then I watched her jump up again. This time the bottom of her shoes began to fill my vision. Everything seemed to move in slow motion as if time had slowed down. I watched the design on the bottom of her workout shoes slowly move closer to my face. I remember being intrigued at the interesting design coming closer, and also at the smell of leather as her soles descended onto my face. Suddenly, I felt the impact of her right shoe across my mouth, splitting my lips on my teeth, and the impact of her left foot on my nose. The bone in my nose couldn't withstand her weight, and shattered under her sole with a loud crunch. I was sure my skull was being crushed under her feet, and I tried to scream but no sound escaped my mouth because of her shoe. She jumped off my face, further crushing my nose and my lips, and causing a bright stream of blood to issue from my nose and lips. As she continued jumping back down my body I grabbed my shirt off the floor beside me and wiped the blood off my face before it could run down and stain the carpet. Once again, I was not prepared for her jump onto my groin area, again crushing my cock and my balls, and almost causing me to double up. She continued to jump up and down my body, twice more crushing my face under her soles, and once more crushing my cock and balls. The front of my face was completely flat, my nose hopelessly broken, and my lips smashed against my teeth.

I was semi-conscious and was only dimly aware that she stopped jumping and began to jog on my chest. The thud of each footfall forced more air out of my lungs, and the tempo was such that I didn't have time to get a breath before her other foot slammed down onto me. I managed to get a little air when she began to jog down my body, jogging first on my stomach, then on my groin. As her feet alternated stomping on my cock, I began to feel the first stirrings of a climax. After about 10 seconds of this treatment on my cock, I experienced the most incredible climax of my life, shooting cum all the way up my body to my neck. This infuriated Mistress Xaviera who jumped as high as she could from my cock onto my chest and then onto my face, and began a high intensity run in place on my face, lifting her knees high and slamming each foot as hard as she could onto my face. Each footfall felt like a small explosion on my face. Mercifully, after about 15 seconds I passed out and gained a temporary respite from the punishment.
