"Why don't you stretch out and warm up" I said, "and then we can get started."
Over the next five minutes or so each of the girl's went through their warm up drills, stretching against the bar and doing easy calisthenics. I then told each girl to take a piece of aerobic equipment and run through t en minutes of exercise. Gloria hopped on the treadmill and set out at a brisk walking pace. Ann mounted the stationary bike and Susan seemed to frown as it was only the ski machine that was left for her. I saw that she was a little awkward on the ski machine, so I suggested that she not try and use the handropes, but lean against the pad at her hips for support while she worked to get the hang of the correct balance and rhythm. I told the girls that they would rotate among the equipment every ten minutes so that they would have a full thirty minutes of aerobic work.
I stepped back to watch my "class" at work. Gloria and Susan were both interesting to look at, though in different ways. Gloria, although too short to be considered beautiful in a classic way, had an interesting appea rance. She had short, curly black hair, with dark brown eyes and a quiet manner. She was a little too busty for the proportions of her figure, and as I watched her closely I was clearly able to make out the outlines of dark colored nipples pressing against the fabric of her leotard.
Susan had a more athletic appearance, despite her clumsiness on the ski equipment. She had a good dancer's type figure with discernible muscle definition. The semi-transparency of her tights, which encased her bottom o ver the back of her thong-style outfit encouraged me to imagine what she would look like nude, at least from the hips down.
These observations had an arousing effect on me, which reminded me of Ann's cleverness. As I felt myself starting to have an erection, I realized the predicament which my loose-fitting nylon shorts presented. I realize d that if I were not careful, and I was not sure whether I wanted to be careful, I might find myself lengthening and then peeking down the leg of my shorts or, at the least, tenting those shorts in a conspicuous way.
At the ten minute mark, I had everyone change equipment. Ann took over on the ski machine and Susan went over to the treadmill with Gloria taking her turn on the bike. Ann was much more experienced and adept on the ski er. Susan promptly set out at a good jogging pace on the treadmill, but Gloria was having a little difficulty with the bike. The source of the difficulty was obvious. The pedals had been set for Ann's longer legs and G loria's feet kept slipping out of the pedals on the bottom of each downstroke. I went over to the bike to help Gloria by adjusting the height of the seat. As she swung her leg to dismount from the bike for a moment, she brushed up against me and with that casual contact I knew she felt, as I did, the contact between her thigh and my semi-hard state. That only served to make my sneak appearance only that more imminent.
The last rotation through the aerobics cycle was more straightforward, and by the time it was finished, each of the girls had a slight sheen of perspiration. I told everyone to help themselves to some juice which from a pitcher which was set out in a corner of the room and each of the girls served themselves while I pulled a bench into the middle of the room and arrayed some dumbells next to the bench for the next segment of the workou t.
I asked for a volunteer to go first and in the absence of a volunteer, I told Susan to lie down on the bench on her back. I handed her two ten pound dumbells and told her to flex her arms and then raise and lower the du mbells, pushing them up from her chest and holding them steadily for two sets of ten repetitions. I stood behind her, at her head, and spotted her through the routine which she completed handily.
It was then Gloria's turn. She started out well enough, but then seemed to run into a bit of trouble. I noticed that as she lowered the dumbells she was lowering her arms at her sides which had the effect of stretching her top tautly against her chest. My gaze focussed on her nipples which seemed to be presented through the material and I noticed then for the first time a small hard item that seemed to be resting on one nipple underne ath her leotard. As I straddled the bench to help Gloria in her struggle with the weights, I noticed that she was looking up the pants leg of my shorts and I knew that her view was completely unobstructed. I pretended n ot to notice where she was looking and Gloria made no comment. I felt an increased sense of inevitability however to an emergence of my cock below the leg of my shorts.
Ann was next. I knew Ann could handle the weight easily, so I gave her two fifteen pound dumbbells. She blasted her way through two repetitions and then yelped "Ow."
Gloria and Susan looked over in concern and I asked Ann what was the matter. Making a motion towards her chest Ann said that the wire in her bra was pinching her. She decided to solve the problem.
Quickly, Ann pulled her arms out of the sleeves of her top and then pushed the fabric down towards her waist. She then released the clasp at the front of the bra and shrugged it off. She sat upright on the bench with h er considerable breasts resting on her stomach and showed everyone where the underwire in one cup had protruded through the bra material. Ann then lifted her right breast up and without any self-consciousness examined he r side to see if there were any visible scratches. Satisfied that she had solved the problem she then resumed her position on the bench and extended her hands to receive the weights. That she did not bother to slip on h er top did not seem to bother her. I handed Ann the dumbbells and watched her complete the first set of repititions with her large breasts now splayed out at her sides. Each repetition caused delightful reverberating mo vement in her breastflesh and, despite the intimate familiarity I had acquired with Ann and her body over the years, the sight of her exercising in this manner was overwhelmingly stimulating. The effect of Ann's actions on me were immediate and had to have been intended by Ann. I had no ability to control my arousal and I knew that the head of my penis had emerged into plain view along my leg below the fabric of my shorts. I saw, as I stood astride Ann, that she saw what happened and her response, which was to run her tongue along her lips, was also seen by Gloria and Susan.
Ann dropped the weights at her side and reached up with her hands and grabbed my backside and pulled me directly over her and then, pulled my hips in a downward motion which caused me to widen my stance and dip myself to wards her now open mouth. She mouthed me for a few seconds in this awkward position and then released me.
Susan's reaction was to say "That looks like a fun way to workout" and she stripped out of her clothes and said "I hope it's my turn soon." Gloria said nothing, but also joined Susan and Ann in removing her workout atti re.
As Ann sat up and pulled my shorts down around my ankles, I looked over at Gloria more closely. I saw that, like Ann, Gloria was shaved completely and I also noticed that one of Gloria's nipples was pierced through whic h she wore a ring which had a gold letter "D" dangling.
At that point, I was no longer in charge, and Ann directed me to lie down on the bench. Susan acted first and sat astride me and pulled me into her. With her feet on the floor, she started a motion to raise and lower h erself in time with a rhythm she established. Ann came over to the head of the bench and placed herself directly over my face. I did not need a special invitation and started to lick and nibble at her while I enjoyed he r familiar taste. Gloria also made her presence felt. I noticed a warm, gentle sensation as Gloria, kneeling at the bottom of the bench, timed long licking motions on my balls and the base of my cock as the latter emerg ed from Susan each time she would raise herself up. I was experiencing a sensory overload as I felt the competing sensations of Gloria's lingual ministrations, Susan's sheathing envelopment of me, and the taste and press ure of Ann's sex against my mouth and face. Glancing down, I saw that Gloria's hand was busily engaged in her own stimulation while we pursued these motions for what seemed like an eternity of pleasure. Finally, with a muffled groan, I felt myself release inside Susan who seemed also to have acheived a resolution by this point. I felt myself shrink and recede within her. As Ann stood up from her position above me, I pulled Susan down towards me and completed our introduction with a long kiss. As Ann's juices were coating my chin and mouth, I knew that at least indirectly, Susan was tasting her too.
