If the weights on your nipples became to heavy, dropping them to the metal plate would cause the Big-O to kick in. If your legs got tired and you went off your tip toes and onto you heels, The Big-O would also kick in... with the clit vibrator!
Just then it became obvious just what you were in for... you weren't quite sure what to expect from all this, but being the gamester you are... you were willing to play along... not to mentioned the fact that you were becoming completely turned on at the thought of what sensations this souped up contraption could give!
"OK my dear... I think you’re all set. ’ I said ‘You can try to avoid the inevitable if you like but I’m afraid your in for one hell of a ride... like it or not! You know what to do to stop and start the machine, but your absolute ability to control it is to be determined. Remember that gravity can be relentless (don’t you just love physics and sex together!) and sooner or later you will succumb to the Big-O. And when you do... this baby will have you cuming like a wild woman. Also remember each orgasm you have will weaken you further, until you can neither stand on your toes nor support the weights with your nipples for any length of time. At that point the vibrator will continue relentlessly... imparting orgasm after orgasm with increasing intensity... until I shut it off! And by the way... since your 36 today... your initial ride will be for 36 minutes!”
Your eyes were as wide open as I had ever seen them. Your anticipation was indescribable as I went in the bathroom to shower and shave. As feisty as you are, you tried to stay on your toes as long as possible and arched your back to pull up on the clamps attached to your nipples keeping the weight off of the metal plate. You were a beautiful sight to behold---your proud breasts protruding forward and your hard nipples being pulled by the weight attached to your nipple clamps. The muscles of your legs and rear pulled tight and firm as your head was held high in that streak of stubbornness that I love about you. You tried to wiggle but your hands and feet were securely held in place. Your only movements were the two I had laid out for you. And each of these had quite an effect!
Knowing you as I do, you must have lasted for quite a while and even perhaps playfully either leaned forward or backward for a few moments and enjoyed the effect of the vibrator. Your curiosity by now was getting the better of you. After a little while you began to notice the constant tug on your breasts was starting to feel a bit heavy (kinda like the old Chinese water torture bit). You leaned forward to place the weights attached to them on the metal plate and the Big-O started. You tried to resist by pulling the weights off the plate again but couldn’t. The sensations were to much inside you... you were getting EXTREMELY excited! After another minute or two your legs started getting weak and you slipped off your tiptoes. You slid down further on the Joy stick and your clit started rubbing against the special extension. Without thinking your body straightened up and your nipples lifted the weights off the plate. This didn’t stop the Big-O this time since your heels were flat on the pedals. The renewed tug on your breasts only caused your excitement to grow. As you squirmed the weight moved from side to side intensifying the sensations in your breasts. Now you were beginning to fully understand just what these nipple clamps could do to your body! You were REALLY getting excited... and there was nothing you could do about it... even if you tried! Your knees had buckled and the machine and the nipple clamps had taken over! You realized that the inevitable was about to happen. Your first orgasm began to build... and it released with a vengeance!
Somehow, after about a full minute, you got back on your toes and the Big-O stopped. You were still breathing heavily but tried to stop and catch your breath for a moment. You could hold this position for only a few minutes... your breasts were tingling from the orgasm and the light weights still pulling on them. After a few minutes you had to lower them to the plate to relieve the tugging... and the machine started slowly again. You could feel it moving inside you but you stayed on your toes. In this position the machine gently massaged your sex but your clit was not in direct contact with the extension. Nevertheless it was extremely pleasurable. After a few more minutes of this smooth gentle massage, you could stand on your tiptoes no longer. Your heels hit the floor and the vibrator increased in intensity... both inside you and on your clit! Again instinctively your head went back and pulled the weights off the plate and the sensations went straight from your nipples to your clit again. All that went through your mind was ‘OH MY GOD!!!!" Your 2nd orgasm was immense... and I do mean immense! I thought I heard quite a loud moan through the bathroom door but I wasn't sure...
After your second orgasm you looked up at the clock. Only 15 minutes had gone by. You were less than halfway through your escapade! You had never quite felt this level of excitement, apprehension and pleasure all at once. You weren’t sure you could physically make it through the next 21 minutes... and that damn machine never got tired! Within a few minutes you legs began to tremble again. You could not hold yourself on your toes any longer. Once again... the Big-O started up.
As I walked through the bathroom door at the end of 36 minutes, you were at the point of yet another orgasm. Your eyes were totally glazed and you were staring into open space as your hips were grinding to match the movements of the Joy stick. I was sure that this was not your first orgasm. Your wetness was streaming down your body and down your thighs. I was just as sure that this was not even the second or third. I don't know whether it was seeing you ready to achieve another orgasm as I came through the door, or perhaps the excitement of seeing you in complete erotic fulfillment, but I know that I was harder than ever before.
I am not sure you even realized the moment that I disconnected the power switch and removed the nipple clamps from your breasts. Your hips kept moving, back and forth, on the vibrator and your eyes continued to stare forward. Perhaps reality began when I gently lifted you off of the mount, and carried you into the bedroom resting you face up on the bed. You were covered with perspiration, your breathing was rapid, and you seemed to be in a trance like state.
It took only a moment for me to remove my robe, gently spread your legs a bit wider, and then help you towards your next orgasm. I knew at that point that you had returned to this world, as your legs locked around my waist... your ankles pressed hard against the small of my back and you looked up at me with that mischievous look of wonder in your eyes.
Your orgasm and mine, coming at the same time, must have registered on earthquake equipment somewhere. Not long after that, we were both lying on the bed, your body snuggled next to mine.
When I awoke, you were still snuggled in my arms. As I slowly opened my eyes, I saw you, looking up at me. Those eyes of yours, wide open, and sparkling, were again speaking to me when nothing else could. You tried to speak but couldn't... one of the few times I recall you being speechless! Nevertheless I knew what those eyes were saying... I smiled and said "Happy Birthday sweetie!... I love you"
