Janet and the water tube

(repost)

Doc wanted me to test the water tube before he put Jenna or Brianna in it. So I went over to that section of the laboratory and made sure it was functioning properly. I tested all the valves and the corresponding controls, making sure everything seemed to be in order.

For a moment I paused, staring hypnotically into the water tube. I could almost imagine Jenna or Brianna in there trying to hold their breath while locked into the foot supports at the bottom. They are the two volunteers the doc uses during his drowning experiments.

The mental image of them writhing around as the doc pushed their limits and then drowned them was enough to get me all worked up. I’m not much for having an encounter with another female. But picturing them holding their breath in a flooded tube was enough to make me tingly all over, especially when I imagined it could be me in there!

It suddenly occurred to me that I wouldn’t truly know if the water tube worked properly unless someone had actually been inside! Oh, the controls worked fine and all. It’s just that I found myself wanting to be inside holding my breath in the worst way!

I set the controls to run some automatic cycles of draining and refilling, something the doc might pull on one of his amorous volunteers. Then I looked all around to make sure no one was watching. When I confirmed I was all alone I shed my clothes lickety-split and then rushed naked up the steps and through the door to the top of the tube.

I was trembling with excitement when I dropped into the tube with a quiet splash from the opening above. I had about a minute before it started its cycle so I reached up and latched the cover closed above me. Then I filled my lungs and worked my way down.

When my toes touched the foot supports I slid my feet into each one. Then I stood there and held my breath. A moment later I heard the sound of a valve opening and the tube started to drain rapidly.

I was so turned on standing there naked! Anyone could have come by and seen me! My nipples were hard and my pussy was wet as I imagined myself in Jenna or Brianna’s situation, getting ready for another of the doc’s experiments. Well, actually he’s an assistant to Doctor Crocker, but we still call him “Doc”.

The water totally drained, leaving me trembling excitedly. Thirty seconds later it began swirling back in from the base of the tube. It filled quickly and it only took another thirty seconds before it reached my crotch.

I gasped, trembling like crazy as the water kept rising. In less than a minute it had covered my breasts and was rapidly climbing up to my neck. I took a really deep breath seconds before it swirled up over my nose. Then I was totally submerged, the water having taken a little over a minute to totally envelop me in its liquid cocoon as it continued to race up to the top.

My pussy was on fire as I held my breath. I imagined I was Jenna or Brianna, preparing to drown for another one of the good doctor’s experiments. Then I heard the sound of another valve opening and the water started to drain back out.

‘Good!’ I thought to myself. ‘By the time the water level drops back down I should have been holding my breath for about a minute.’ This was confirmed by a clock on the back wall someone had put up, allowing me to time the system.

My lungs weren’t too bad when the water dropped below my mouth, allowing me to breathe again. After all, a minute was fairly easy for me. But it didn’t pay to try long breath-holds all at once. Better to work up to them!

The water stopped just above my crotch and I panted heavily for breath. Then I heard the sound of valves again. The tube was filling back up.

I watched the clock on the wall as the water climbed my quivering body. I was already regretting not having brought a play-toy in with me. But I knew I was going to get off anyway before it was all over! Besides, I’m pretty talented playing with myself whenever the mood strikes!

I got about a full minute of air to get ready before the water level reached my chin. I quickly filled my lungs and then settled in for a longer breath-hold as bubbles dribbled out of my nose. So far the automatic programming was running true to form, leaving me virtually the exact amount of time I’d plugged into the coordinates to get my breath back. But this time I was going to be under for a minute thirty.

I watched the clock on the wall and then looked up to see how well the water was filling the tube. It was almost full before the valves kicked in again. I had another forty-five seconds before it dropped back down past my lips, allowing me to breathe again.

I stood there imagining the doc watching my naked body. I could just picture that bulge of his and I felt an erotic shiver ripple through me. No wonder Jenna and Brianna liked the doc to watch them drown! It must have been exciting knowing they were turning him on! I actually found myself secretly wishing he was watching me at that very moment.

The water level dropped past my lips and I gasped for breath as I checked the clock on the wall. It had been about a minute thirty, give or take a second or two. The system was running great!

I panted heavily, working to get my breath back. I’d set it up for one more session that would keep me under for two full minutes. That was easily within my limits. But there was that delicious flicker of uncertainty in the back of my mind. What would happen if today I’d miscalculated and I couldn’t GO two minutes on one breath??

I heard the valves as the water started to rise again. If I panicked I could easily slip out of the foot supports and go on up. But the tube would still be full before the water level started to drop. Still, I knew it should go back down within the time frame, giving me the air pocket I might need if I for some reason I couldn’t hold it long enough.

But wasn’t that a part of the thrill? Was that one of the many reasons Jenna and Brianna liked pushing things until the doc drowned them in his experiments? I found myself actually considering volunteering for his next session! It wasn’t the first time I’d thought about it. And as erotic as the whole damn thing was I doubted it would be the last.

I checked the clock on the wall and discovered I was well into a minute. A quick glance up showed me the water tube was completely full. There was no air pocket whatsoever. If I were to get into trouble now I would be forced to wait until it started to drain again.

The thought was arousing as hell and I finally succumbed to the temptation by running my hand down and fingering myself. My body writhed as bubbles trickled out of my mouth. Gawd; it was so hot! My nips were really hard!

I closed my eyes and concentrated on the pleasure I was fingering into myself. It wasn’t long until my lungs began to feel the strain. The thought of miscalculating or something going wrong and being trapped inside the water tube really got to me and I began fingering myself like crazy!

I knew I had to hurry if I was going to cum underwater because I could tell the water tube was draining again. I could feel the strain in my lungs of holding my breath and I really fingered myself. Then I popped off with a wonderful climax, one that flushed hotly through my body.

The water dropped below my head and I waited until it fell below my lips before I opened my eyes and gasped for breath. That’s when I saw the good doctor standing there at the controls, an amused look on his face!

Oh, gawd…

I went beet red with embarrassment as he studied my naked, trembling body. “Mind telling me what you’re doing in there, Janet?” he asked with a smile.

“I’m just checking the water tube like you asked, Doc!” I sputtered nervously. “I’m just checking to make sure it works properly is all!”

“Then let’s really check it, shall we?” he suggested with a grin. A moment later he tripped the override switch, deactivating my program. An instant later the foot supports clamped down tight around my feet as he toggled the controls!

“Doc?” I called out nervously as my heart rate skyrocketed. A moment later he gave a good, hard twist on the main valve. Water came boiling up from the bottom and I had seconds to fill my lungs before it rushed up past my head!

I grunted in alarm as an incredible jolt of sexual tingles hit me hard. This wasn’t at all what I’d planned on! I was only going to sneak into the water tube for a quick check and a quickie orgasm before leaving! Now I was trapped inside, my feet firmly secured inside the foot supports as the doc watched me!!

“What do you think, Janet?” he called out to me. “Is it working properly?” I nodded anxiously, my nipples rock hard.

With a hard twist on the valve in reverse I heard the water start to drain. Relief flooded my being and I nodded and bubbled. The water was almost a foot over my head and draining fast.

All of the sudden Doc grabbed the wheel and gave it a good hard twist in the opposite direction. The water instantly stopped raining and began to rise again! My eyes flew open in astonishment! Gawd! I hadn’t even been allowed to get a breath yet!

“You think Jenna and Brianna will like this?” the doc chuckled at me. My lungs really began to strain and I reached out and pounded on the glass. Bubbles poured out of my mouth as I cried out in horror, my pussy throbbing like crazy.

With a quick twist of the valve the water started to drain again. But this time I was anxious for it to drop below my head so I could get that breath I needed so badly. Then the doc twisted the valve again. The water stopped draining the moment it touched the hair on my head!

I looked up and waved my arms up above the surface, thrashing about for the air I needed so badly. It was right there but the doc wouldn’t let me have any! My lungs were on fire and I was going to drown mere inches from the damn air pocket!

With a cruel smile he twisted the valve. The water dropped past my lips and I gasped madly for breath, my body trembling like mad. Then he twisted it again and it flowed right back up over my head! I grunted in alarm until he twisted the valve once more, allowing the water to drain out until I could breathe again!

“So what do you think?” he asked again. “Think they’ll like it, Janet? Or maybe I should test it out on somebody else first?”

I coughed and sputtered, desperately trying to get my breath back. Then Doc twisted the valve again! My eyes flew open in horror and I frantically filled my lungs seconds before the water flowed up past my face!

I stared at him in horror, grunting in alarm. To my shock he unzipped his fly and pulled out his cock! Then he actually started stroking it right there in front of me!!

I couldn’t believe it! He’d never acted this way with me before! Now I got the distinct impression he was actually going to enjoy watching me drown! It filled me with a terribly erotic fire as my lungs began to protest.

I looked upward, only to see he hadn’t left me any air pocket at all! No matter; my feet were still trapped inside the foot supports. I wasn’t going anywhere until he activated the release!

I watched him in absolute astonishment as he stroked himself. I couldn’t believe it and I began thrashing about. He was actually going to watch me DROWN??!! Why that BASTARD!!!

My lungs began to burn as my heart hammered in my chest. Then in a sudden panic I reached out and began beating upon the glass again. That just made him smile and stroke his cock even more!

Who the hell WAS this guy? Had Doctor Crocker even bothered giving him a background check? I was going to drown in this water tube… and no doubt he was going to drown Jenna and Brianna next!!

I screamed my breath away as I pounded upon the glass. Then my lungs gave out and I sucked water down my throat. That’s when he aimed his cock in my direction, cum spurting out to splatter against the glass!

I stared in horror, astonished that he was cumming as I was drowning!! That’s when I came so very, very hard! My body started thrashing about as my mind screamed helplessly…

I’M DROWNING! I’M DROWNING! I’M DROWNING! HE’S DROWNING ME! THE DOC IS DROWNING ME!

…and then I woke up!

The sheets were wet! I’d squirted so hard from my orgasm that I’d soaked them!

I shook the remnants of the dream out of my head, remembering that we didn’t have that kind of water tube on the premises. My body was tingling from wild aftershocks. But I couldn’t help dwelling on one rather disturbing thought…

Was that why I’d had such an incredible dream? Was I really considering volunteering for one of Doc’s drowning experiments some day?? Was I really that crazy???
