The Hydro Chamber 

Chapter 1: Week Nights at the California Aquatic Center 

I had been meeting Keri at the pool for several months now. We were not dating … but we did both seem to show up on Tuesdays and Thursdays. As the winter grew colder and the snow flew, we enjoyed the warm water and the activity. The pool was a semi-public facility but it required a pretty significant yearly fee. This had the effect of both keeping the number of visitors down and allowing the management to spend pretty lavishly to improve the center. 

Associated with the Aquatic Center was a 4-story research facility but very few people knew what went on in there. (I know that in those days, I didn’t.) Keri and I spent our time swimming and diving in the deep water and just generally playing around like two 12-year-old kids. We were getting pretty comfortable with each other BUT we were certainly not an “item” so we did not touch except for the passing hand or foot grab. 

We made up games and our current favorite was Underwater Dancing that ranged from underwater ballet to fast dancing that really burned up the old oxygen. Oh yea! Of course, slow dancing also meant a little touching so there was that side benefit. I think that the other people in the pool thought that we were crazy but we enjoyed ourselves without a care. 

Chapter 2: Chosen Ones 

A beautiful blond, in an athletic style blue sky colored one-piece, glided up to us as we rested after a strenuous game of underwater hide and go seek. She said, “I noticed that you like to play underwater and both can stay underwater for very long periods. Are you interested in improving your bottom time?” 

“Sure,” we both said together. 

She said, “Well watch this!” With that she slipped under the surface pointing up at the digital clock on the wall as she sank. The time showed that it was just hitting 09:45:30 in the evening. That shouldn’t be too hard to remember. The woman settled to the bottom ON her bottom and a few bubbles rose from her nose. We looked down at her and laughed – what a nut we thought. 

Keri and I discussed our own breath holding records and when we made them. Mine was motionless in a bathtub face down with a timer that beeped off the 15-second marks. She said that I had helped her set a new record three weeks ago when I hooked her bikini bottom on the bottom rung of the pool ladder. She said that I had swum away and left her struggling for almost two minutes before she ripped off her bottoms and sprinted half naked to the showers! That would explain why she did not wear the cute little white string job that I had come to know her for. 

The clock now showed 09:46:45 so 75 seconds had passed with this strange but wonderful woman sitting on the bottom of the pool below us. I swam down. She was just sitting there looking at all of the activity swimming above her. I settled down next to her and guessed that it was now over a minute and a half. She showed no sign of discomfort and in fact, it appeared that she was not even really holding her breath. She lay down on her back and closed her eyes with a small smile on her face. 

I waited around watching her and looked up at Keri treading water just a few feet above us. I reached up and took her ankle giving her a chance to get a breath and pulled her under. Keri gave me the “two” finger sign, which I figured to be the time that this girl had been underwater so far. We watched the motionless woman and frankly I began to get a little horny. I put my hand on her stomach and felt her tighten up a bit as she felt my touch. She took my hand and guided it down the front of her thin spandex but I was afraid to go much lower than the top of her pubic bone - at least not with Keri watching. 

Keri watched me for a few seconds but then kicked off and swam to the surface. I followed her up to make sure that she was not offended. I surfaced next to her and quite the contrary she was in awe. She observed that the clock was now at 09:46:55 so this girl had been underwater for three minutes and ten seconds! This was very good. Now we were both interested! 

I swam down to the girl and pointed to the deck of oversized underwater poker cards that kids sometimes play with on the bottom of the pool – usually in the shallow end. She sat up and shook the hair out of her eyes. I got the cards out and was clumsily shuffling them just as Keri can back down again. She brought her timer and it showed in bright yellow numbers that she had set it so that it had the total time that this woman had been under. The time was now three minutes and forty-five seconds as I dealt the first hand. I drew a couple of ten’s and a couple of fives but the girls had nothing to speak of even after drawing three cards each. I win! 

The woman looked at all the cards and calmly removed her bikini top. So it was underwater strip poker! I looked at Keri and realized that she was ahead already of us both – she had two strips of cloth covering her and this woman and I only had one each! I noticed that a small flotilla of swimmers were watching us and I was more than a little certain that public nudity was not tolerated at this pool. I got ready to deal the next hand and then I got an idea. I swam to the surface, leaving the girls on the bottom, and tread over to the five or six people who were watching us. 

I asked, “Does anybody have an issue with us if we play the next hand? As you can see, somebody is going to end up naked and we don’t want to offend anybody.” They all laughed and said that they were totally fine with it. 

I took a deep breath and sank to the bottom again. Keri had been underwater for almost a minute and a half but the woman had been under for FIVE MINUTES and FIFTEEN SECONDS! She indicated that she wanted to deal the cards and I could see that she was getting pretty close to needing to get to the surface for air. She dealt the cards and I made a big show of looking at them over and over drawing out the time. Keri had been under for two minutes and she was starting to get red in the face. She looked up and then at her cards again and then at the surface. 

The timer was in the home stretch for six minutes so I drew a card to match my three of a kind. Keri drew one but I think that she was on the verge of drowning and would have done anything at this point. The woman took two and looked at them and then at both of us. She placed her cards face down, slipped out of her bikini bottoms, took Keri by the hand and with a strong kick whooshed them both to the surface. 

The timer read six minutes and ten seconds so that meant that Keri had stayed underwater for three minutes on her own! I was in awe as I turned over the woman’s cards. I know that this is not considered sportsmanlike but I had to know. Her hand was three Aces and two Queens! No matter how you slice it – she had the winning hand but just wanted to lose and take her panties off. 

Chapter 3: The Bold Exit 

I met them on the surface and “forgot” to bring the surrendered swimsuit with me. I told the woman that I would go down and get it but she assured me that she would get it after the pool closed at midnight. She also said that she was the Director of Science for the pool and so she thought that she was not in any danger of loosing her privileges. She winked and told us that the pool has seven underwater cameras that act as underwater lifeguards but she also had some footage of other MUCH more R and X rated scenes that had taken place in the last year. 

I gulped but remembered that Keri had not done anything so we were not “caught-on-tape” but we could have been if there wasn’t anyone in the pool on some of the nights. The woman introduced herself as Cindy and asked us if we wanted to join her in her office and watch some of the footage. We giggled like schoolchildren as we climbed out of the pool and followed her to a door next to the door to the ladies locker room. We entered and were met by a floor to ceiling wall of glass that looked right into the girl’s locker room! It must have been a mirror on the other side. 

“Do you have anything like this on the men’s side?” I asked as I slowed to watch a couple of twenty-something blonds in the shower lathering up and chatting like silly little girls. 

“Of course,” she answered, “I am sure that you would agree that it would not be fair to just have a view into the girl’s locker room.” Besides, I am sure that you and … “Keri” (I filled in her name)… have seen each other naked many times” 

Keri said, “Well actually, we haven’t ever been nude together but being in wet swimsuits in a pool for hours is almost the same thing. I mean, I can tell how big his package is and when his is getting … excited.” 

I blushed a bit. I said, “And I can tell when she is cold and that she, well, trims her nether region.” Now it was her turn to blush with me. I continued, “I am sure that if I bumped into Keri on a nude beach we would not think a thing of it.” 

Chapter 4: Hot Tub Magic 

Cindy was still unclothed as we waked to her main office and then to a ships ladder that rose above the pool level to a room with a hot tub overlooking both of the locker rooms and the pool. In the corner were a desk and a video monitor. She said, “I am going to slip into the tub and you are welcome to join me if you wish.” 

Keri did not hesitate but stepped out of her wet suit and hung it on a hook in a near-by shower. In seconds she was in the tub and I was left standing there. I knew that I had to get in to the water before my dick came to life at the sight of all the wet nude pussy splashing in the water. It was already too late so I attempted to step in with my suit on. 

“Not so fast,” Cindy said. “We have rules here you know cowboy!” 

“I can’t get naked now,” I whined, “I am getting an erection and it is embarrassing!” 

“Well, at least we know that you are normal,” Keri said. “I thought that either you were very polite or gay or something. All those times that I let my top slip playing underwater tag and you just looked the other way!” (Now it all made sense!) 

I let my pants drop and my dick sprang to attention but I climbed into the tub anyway. I slid down into the water and let the heat drive away the cruel winter that was waiting for us outside. Keri and Cindy talked and squealed like old friends and sat on one side arm-in-arm. Keri asked her how she managed to accomplish the underwater feat and she said that it was a result of training and mind over matter. She said that she could get to five minutes on a regular basis and under special circumstances she could get to almost seven minutes. She then looked thoughtfully and said, “Under really special circumstances, I can get to nine minutes but that takes some work. There is a situation that I have actually stayed underwater for over an hour with out surfacing and without using breathing apparatus.” 

She let it hang there for Keri and me to think about. And there was a lot to think about. As we sat in pensive silence, Cindy sank underwater and we could feel her stretch out on the bottom of the tub between our legs. She smiled up as us and blew some of the air that she had taken down with her, out of her nose. It wafted to the surface and I commented that we would not see her for a while. 

I said to Keri, “Do you have ANY idea what she is taking about?” Keri looked at me and then around the room for clues. On the wall was a poster for extreme breath holding using pure oxygen and aids to keep the body underwater. “Well I think that we figured out the first time of seven minutes – though that still doesn’t explain the six plus minutes that she did in the pool just a little while ago”, Keri said. 

“How long has she been under so far”, I asked? 

“Only a couple of minutes so far but I suspect that she is going for at least five minutes again this time. 

Chapter 5: The Book 

Keri climbed out of the pool to do a little nude detective work. She approached the desk and prominently on top in the center was a large leather book that was open to a page of photos that showed a group of swimsuit clad young men and women sitting on the bottom of a swimming pool with the number 61:05 stamped on the corner of one of the photos. The entire page was labeled; The One Hour Club. She paged through the book and found another series of photos that showed a young redheaded woman with her hands tied behind her back being helped down into a large tank with what appeared to be a lid that could be locked shut. The tank had pipes and tubes leading from it and an array of computer monitors and measurement probes. 

Keri picked up the book and turned to bring it over to me. Cindy was still in the bottom of the pool and had reverted back to her underwater dreamlike state. The timer on the wall indicated that she had been under for four minutes and forty seconds as a rush of bubbles splashed to the surface. I assumed that she was going to come up now but I was very wrong. She turned on her side and placed her hands under her head and resumed “sleeping”. 

Keri and I turned back to the book that she had set on the step to keep it dry. We looked at several pages of internal reports that showed high oxygen saturation breath holding but we hit pay dirt when we got to a tab near the back marked; Hydro Breathing. It related to the girl that had been locked in the chamber and got right to the point. This was a system in the early stages that allowed a person, or any mammal, to breath liquid – in this case plain ordinary water – that had been supersaturated with oxygen so that it was almost 16% or just a few percent less than ordinary fresh air. It described how the first test subject, a girl from a college, had been imprisoned in 1500-gallon chamber of the liquid and left to “drown” as the cameras and monitors looked on. 

She had survived with some ill effects but she readily volunteered to undergo seven more experiments over the subsequent three weeks. By the fifth experiment, the scientists were getting more bold and they cranked down the oxygen to just above 10% but that caused the subject a great deal of misery. Several levels were characterized and it was determined that 13% was the minimum with 25% being the practical maximum. 

Chapter 6: Eight is more than a Number 

Speaking of distress, Cindy had now been underwater for four minutes and fifty-five seconds now and we had quite lost track of her. I slipped under to check her out and she was still lying on the bottom but I could see that her eyes were open and she was looking at her timer. She held up eight fingers and then took my foot and placed it on her chest to hold her down. She wanted me to hold her underwater for three more minutes??? 

I surfaced and told Keri of the communication that we had just had and she shushed me and pointed to the paper that she had been reading. We read that the college girl had not completed the last test because she had sneaked into the testing facility and entered the water tank with her boyfriend. She had turned on the system correctly and apparently had briefed him on what to do but they had let the top of the test tank slam shut trapping them both underwater. What she did not know was that turning on the system also turned on the video cameras so the entire tragedy was recorded! 

They survived underwater for almost two hours but eventually the oxygen tank was depleted and they suffocated soon after. 

The timer was now up to six minutes and thirty nine seconds and Cindy was starting to shake and jerk beneath my feet. I would let her up if she wanted to but I guessed that my weight was helping her stay on the bottom. Every so often, a “bloop” of air escaped from her mouth and ran up my legs caressing my balls! How could I want to stop this? I told Keri that Cindy was now up to almost seven minutes but she seemed to be close to drowning. She showed me a reference in the paper that she was reading that directed her to videotape by a special code number. Sitting on the monitor next to the desk was that very tape! I really wanted to see the drowning and learn more about the work. 

Keri volunteered to go down to check on Cindy and she was up in a few seconds reporting that she WAS drowning. I noticed that she had quit bubbling but I assumed that she had just gotten control of her dwindling air supply. I went down with Keri again and could see that if she could just hold on for thirty more seconds she would make the eight-minute mark! It seems like a little thing, thirty seconds, but when you are underwater time is a different animal. 

We had all heard of people drowning in only thirty seconds and that is without the nine and an half minutes preceding that! Cindy was drowning right before our eyes and we both grabbed her arms and hauled her to the surface. At the surface, she held her head under as she checked the time one last time. Damn, she must have thought, there were still twenty seconds left to go! She choked and gurgled with her face down in the water and her feet came up off the bottom as she tried everything to keep her head underwater. 

I started counting down from fifteen and she relaxed a bit but I could still feel the water sucking its way into her windpipe and her body convulsing it out again! Nine, eight, seven … she grabbed around our waists and pulled her body down as more bubbles choked from her mouth … five, four, three … we started pulling her up and just as the clock hit ten minutes, we pulled her up into the air and she vomited a enormous fountain of water! She could not talk for a while and she sank back into the water chin deep. We held her up as she choked up what must have been a liter more of water. 

Cindy could not talk but she had a big smile on her face. She bent over one more time and water sprayed out of her nose and mouth – a sneezing fit was the culmination of her body ejecting the water that she had both swallowed and inhaled. 

When she could talk, she said, “Well what do you think? Did you know that at just under seven minutes, I started inhaling water and managed to get enough oxygen from it to stay alive for the last minute?” 

We were stunned! “You mean,” I said, “This pool has oxygen in it like the experiment in the book?” 

“No, this is normal water, it has only 4% dissolved oxygen but if you put yourself into a trance and force yourself to breathe in and out you can get enough oxygen for a while to stay alive,” Cindy explained. 

Chapter 7: Research Facility: 

That Friday night we met at the back entrance to the research facility and were led inside by a young assistant. She showed us around for a bit but for the most part it was just boring labs and offices. At the end of a hall was massive airlock door to a chamber that led to the most wonderful place that I have ever visited! 

The room was 60 feet in diameter and crowned up to a rounded ceiling almost three stories above our heads. In the exact center was a 40 foot round pool – evenly deep at the edges dropping into the center that appeared to be of unknown fathomable depth. 

Several lab technicians were off in a room off to the side of the pool but inside of the pressurized area. They were all dressed in the standard white lab coats and concentrating on a vast array of instrumentation and computer monitors. The temperature of the air was in the 90’s with the water over 85 degrees according to a set of enlarged instruments on the wall! 

“You have the chamber for 1 hour and 45 minutes”, she stated. “You can play around in the water for the first 20 minutes or so but you should drown the first one of you before the half hour elapses. Get that? Thirty minutes and then its glug glug glug. Plan on the other one of you going under after the first one stabilizes hydro-breathing. Then they can assist the air breather.” 

Keri shivered with delight (fear) and took my hand. Cindy continued, “With the increased oxygen, you will be able to hold your breath for almost two X your usual time. So you, Mike, should be able to increase your three-minute and change time to just less than seven minutes. Keri, I think that you demonstrated that you could hold your breath for 3 minutes so count on achieving six minutes!” 

“Yes, but that was very unusual,” she said. 

Cindy walked and talked as she continued the lecture. “It is common for the male, when we work with a couple, to have longer breath holding times. So it is customary for the male to assist the female by drowning her first. Is that what you two want to do?” 

This was really happening – I could not believe it! 

Chapter 8: Purple Tank Suit 

Keri came out of the dressing room wearing a one-piece purple tank suit. I asked her where she got it since she usually wore a red bikini or a black tank-ini. She said that there were a collection of brand new swimsuits in the dressing room and she chose this one because it was different. I commented that in certain lighting conditions, the fabric was almost transparent. She twirled on the brightly lit tile next to the waters edge and laughed as we could clearly see her nipples and pubes. 

She also showed me that it had a snap crotch and that the top and sides were very stretchy. Fun! 

I, on the other hand, had just shucked my shirt and kept on my favorite cut-off blue jeans. I still had my underwear on underneath but they were pretty thin and not restricting. I put my wallet on a chair and took off my watch. We both put on the combination bottom timer and oxygen sensor wrist computer. The device picked up your blood oxygen through a patch stuck to your wrist. The bottom timer sensed when you were holding your breath (I don’t know how) and started counting up in large red numerals. 

I slapped Keri on the butt and said, “Let’s get wet little girl!” 

Chapter 9: Into the Pool 

We hopped down into the swimming pool and waded around in the three-foot deep outer ring section. This ring shaped section was five foot wide and the next step was a big one down to the six-foot deep section. Keri swam out over the gulf to the next ring and dove down to the bottom. She swam along the bottom and I took up position following her around the circle. I suppose that I could use geometry and tell exactly what one complete revolution was underwater ((40 – 10) * 3.14 (Pi) = D, D = 90 feet) but it was simpler to guess that it was just under a hundred feet around. 

After one circle at a very slow pace, we stopped and looked at our timers. They indicated that we had been underwater for 00:55 seconds but we did not need to surface for air yet. We started on another circuit and this time stepped up the pace a bit. At the end of this loop the timers read 01:41 so we were a little quicker. 

Keri swam into the shallow water and up to the ladder. She grabbed onto the bottom step and rolled on her back letting the air escape her nose and bubble to surface. She lay on her back and stretched her arms and legs out. Air bubbled up from her nose and she closed her eyes like she was sleeping. I plopped myself on the bottom next to her and we held our breath together and stayed underwater for five minutes and forty-five seconds! This was very cool! 

After swimming around the ring again we decided to explore the above water portion of the chamber. We climbed out of the pool and shook off. 

Chapter 10: The Water Totter 

At the far end of the pool were a neat collection of toys and contraptions. One was a chaise lounge like chair that had a pivot in the center that allowed the person on it to either be head down almost to the floor or head high and feet to the floor. When the person laid back on it the balance was about three feet from the base to the web bed. At the top and bottom corners were straps to secure a persons arms and legs. 

Keri sat down and lay back with a big yawn. She told me to strap her in for a test run. “Do you know what this is for,” I asked her as I moved down her legs to fit the Velcro straps? 

“Sure,” she said, “It is so you can play a drowning bondage games with me while you fuck me underwater.” 

Chapter 11: Awash 

With Keri securely strapped arms and legs to the teetering bed, I ran my hand down her body to her crotch and then down her thigh. She quivered and told me to do that again. I told her that if she were going to keep talking I would have to punish her. She said that a proper punishment would be to dunk her in the water. I pushed on the device and it moved easily across the tile floor. As I moved it, I told her that when she was underwater, she would have more trouble talking as well. 

The edge of the pool had a shallow ramp leading down into the water. I pushed the water totter over the edge and it slid down into the water with a splash. I came to rest with Keri’s head slightly down so the water was just covering her face. I walked down the ramp and up to her side. She looked at me through three inches of water and pursed her lips to kiss me. I bent into the water and started kissing her underwater as my hand found its way down her body. I put it underneath her swimsuit and slid it gently over her firm boobs. She kissed me harder so I tried to run it down farther but the fabric made it difficult. 

I pulled my head up and tilted her back even deeper. Her pussy was now awash only separated from my lips by a millimeter of shear purple fabric. With her head deep underwater, she was quiet now so I could get to work. I unsnapped her crotch and the suit raveled up so that her fine cunt was open to me. I took some water in my mouth and let it dribble down her crack – her whole body twisted with delight so I did this several more times. I looked up at the timer but it was hard to tell how long she had been holding her breath. 

I pulled her shoulder straps down over her arms exposing her sloshing breasts. My cock was so hard that I though that it was going to split! I unzipped my pants and relieved some of the pressure. Climbing onto to her, I pushed my shorts down but that looked kind of silly so I just kicked them off. I was going to keep my underwear on for a while but I needed to start making love to her immediately. 

Leaving her underwater, I pushed off my underpants and put them and the short on the edge of the pool. Keri was starting to let a few bubbles stream to the surface and I remembered that her wrist timer should have her bottom time. I looked and it showed that she had been underwater for three minutes. I mounted her and drove my cock deep into her. She opened her mouth and air streamed out! I started fucking her and put my head underwater to nibble at her neck and ears. 

Keri was now pretty interested in breathing and was trying to get me to transfer some air to her mouth-to-mouth. I pounded away at her with wild abandon. The totter started to move and before I noticed it, her face was at the surface but she could not get a breath without water going down her throat. She breathed out and tried to inhale but it was as much water as it was air. I pushed her under again and continued to fuck her. 

We went on like this for another couple of minutes but in my passion, I did not help her get air to the extent that she needed or wanted it. Keri and I settled into a steady rocking motion and I all but forgot that she was underwater and needing to breath every so often. There were a few seconds when she came up and in that brief instant she choked and gasped but I pushed her under again before she go too comfortable. Under the water she scrunched up her face and I could feel her pussy clamping down with vice like force. 

Cindy swam up and submerged next to Keri to check in on her. She stayed under for only a few seconds and then splashed to the surface. Liz swam up as well and listened to the news. 

Chapter 12: Getting Serious 

Mike, You have to help her drown now! She has been underwater almost ten minutes with brief gasps of air and water and she is panicking! If she doesn’t get her oxygen from either the air or the water she will suffocate. It was true, I knew that she had inhaled at least half a liter of water and it had to be depleted of oxygen by now. She was not getting oxygen from either source. 

Cindy went back underwater to hold her shoulders down while Liz was on the surface with me. I continued to pump her cunt as she twisted in an attempt to lift her face to the surface again. I held her feet up but there was no way of knowing how much longer she could go. I closed my eyes and lifted my face up to breathe in that sweet sweet air. I heard Liz splash away and soon, except for my panting, it was very quiet. Keri was struggling below me and I was a bit sorry that she was in so much agony. I thrust harder to at least give her some pleasure – or maybe it was just for myself. 

I looked around the pool and enjoyed the solitude of the moment. Looking down, I could see that Cindy was now breathing water from the pool as she floated submerged by Keri’s head. She looked up and gave me a big grin. When did she “drown” herself? I watched her as she swam around us on the bottom in this shallow water and then back to Keri’s head. She got her feet under her and stood up in the mid stomach deep water but she did not start breathing air again. She held the water in her lungs as she leaned over Keri’s submerged upper body. 

Cindy ran her hands down Keri’s chest and cupped her breasts! Keri arched and twisted her head back to put it in Cindy’s shaved labia’s. Her face was all but buried as she pushed her nose and lips up into Cindy’s crack as she lifted one leg to give her better “coverage”. Cindy leaned forward and put her nose up Keri’s pussy that was awash in water and just breaking the surface. 

Clearly it was up to me to communicate to Keri that she was not going to come to the surface again for air until she was drowned. I pushed the water totter over to the edge of the 3-foot step and let it glide down with the two girls to 6 feet level. It landed on its base here in deeper water so but no matter how you rocked it; Keri’s body would be 4 feet beneath the surface! She was still strapped in tightly but her struggles were easing. I swam to her side as Cindy dismounted. 

Cindy placed her two hands with interlocked fingers on Keri’s chest and pushed down sharply. Air erupted from the drowning girl. She shook her head from side to side in a wave of long blond hair. Cindy jabbed her again but far fewer bubbles escaped this time. On the third thrust, Keri stopped resisting and opened her eyes and looked at both of us. 

Keri was out of air so she opened her mouth to the water and let it flow into her tiny body. She choked most of it out in an explosion of fine bubbles and then sucked in a much pull fuller the second time. This did not result in as much choking as the first time and she appeared to concentrate on just breathing out and filling her lungs with water again. I stayed by her side for six more repetitions. It became easier each time. She closed her eyes and relaxed and breathed the water more calmly. 

I stayed as long as I could but at four minutes, my bottom time was up. I swam to the surface of the pool and floated on my back. 

Chapter 13: Time to Regroup 

I was spent! The clock on the wall showed that it was now 10:32PM. Keri had gone under for the first time at 10:19 so it had taken her 13 minutes more-or-less to drown. There she was lying on her back strapped to the water totter in deep water but she now had a smile on her face. Her chest rose and fell as she breathed the viscous fluid catching her breath. I lay on the surface facedown floating above her. 

I was still terrified to breath liquid but out of the corner of my eye I saw Liz unceremoniously sink to the bottom and blow out a steady stream of bubbles from her pursed lips. Without a pause, she turned her face to the surface and opened her mouth wide. I could see her eyes blink several times as the water filled her lungs. She sank to the bottom on her still modestly covered butt. Liz was the only person who was not nude and looking at her was very erotic for me. I pointed to her suit and motioned for her to strip it off. She responded by swimming over to me. 

Now all three girls were underwater hydro breathing so I was the only one left with an attachment to the surface. I lifted my head up and took another breath and submerged again. I sank down to touch Keri’s cheek. I released the strap on her right hand and she took my hand in hers. She pulled me down to her and positioned me over her so that my limp cock was brushing against her milky pussy. 

In the warm silence, Keri reached between us to take my dick and stoked it and my balls causing me to start to become aroused again! I had a good breath and I knew that I could stay under for four minutes so I placed my lips on hers and started to thrust my dick back into her sweet cunt! Kissing her was a strange experience since she was breathing water through her mouth and I could feel the water filling her mouth as she gave me a tongue job. She tried to playfully get me to inhale water from her mouth into my lungs but I was not ready yet! 

Liz came up next to us and I put my hand around her waist and into the back of her bikini bottoms. I ran my fingers down over the curve of her bottom and grabbed a hunk of flesh. Liz leaned over Keri’s face and placed her lips over the drowned girls mouth. She blew water into Keri’s mouth and filled her lungs to their fullest capacity. Keri in turn blew the water back and they exchanged these watery kisses for several minutes as I concentrated on her lower regions. 

As I fucked her underwater in complete bliss a disquieting thought started to form in the back of my mind. I had lost track of Cindy. Was she planning to ambush me and drown me while I was fucking Keri? It made perfect sense. She had said that the entire session was 90 minutes long and it was best if we could spend 60+ minutes underwater. I guessed that the time was now 10:45 so I had only fifteen minutes left! 

I rocketed to the surface with a start and looked around. I swam to the side of the pool and pulled myself out (secretly wondering if I really wanted to be caught) and walked dripping over to the lab technician window. On the way I stopped to wrap a towel around me but it was kind of silly since I knew that they had camera in, around, and underwater in the pool. They had been watching Keri and I screw for the last half hour! 

Chapter 14: Are we Alone? 

I picked up the phone and the lead scientist picked up his in the booth. “Where are the girls?” I asked. He turned a video monitor to face the window and I could see that Cindy and Liz were swimming at the bottom of the pool where it dropped down in the center almost 30 feet deep. They were looking through the glass windows that separated them from a huge aquarium with fish of all types that surrounded them. Drowning me was the farthest thing from their minds. 

I laughed and turned to dive back into the pool. I barely made a splash as I launched my trim form into the warm water. I swam underwater over to where Keri was still tied up and released her other wrist and then her ankles. She lifted off the water totter and took my hand. She wanted sex again! I had been underwater for under less than half a minute so I was all ready to go. 

I led her to the ten-foot deep section and we sank to the bottom of the ring. I sat her on the bottom and got positioned over her. I looked at my timer and saw that I had only been underwater for 43 seconds. Great! In the past, this would have seemed like a relatively long time but now this was only the beginning. We engaged and started a protracted unhurried coupling with our genitals locked in total bliss! I drove her along the bottom until her head was hanging over the edge to deep level. From there I could look over and see the shaft leading to the aquarium viewing area below. That’s where the other girls were. 

We made love for first one minute and then another. At two minutes and twenty seconds, I started feeling a little light-headed. Through I was not ready to drown yet, I was much less worried than I was in the past. After all, if I lost contentiousness, would not die. Keri was an animal – I suspected that she had forgotten about my need to breath. This must have been what it was like when the mermaids drowned the sailors. Maybe it was an accident. 

I was really short of breath now, so I pushed us both (still joined) off the bottom and we ascended the short distance to the surface so I could get a much-needed breath of air. On the surface I gratefully filled my lungs but Keri kept her head underwater – her air supply was now assured just under the surface. The top of her head broke the surface and it was weird not to hear her voice and hear her panting as she shared our after diving laughter like we did in the pool. 

I took a huge breath and let us sink to the bottom again. I missed the ten-foot level by a few inches and we continued to sink to the deep chamber level. This time I was planning to go to at least five minutes underwater or drown trying! As we sank, I stood her on her head and pulled her legs up around my face to make oral love to her wet wet pussy. I grabbed onto a ladder rung and held us motionless at what must have been almost 20 feet deep underwater. She locked her legs around my neck and took my cock into her mouth. She practically inhaled it back into her throat. So this is what head really feels like. 

After four minutes I really needed air so I left her at the perch and swam to the top for a quick breath. I rolled over and sank back to the place I had left her but she had let herself sink down the shaft to the bottom. The other girls were in one of the side passages so I knew that we were alone. I pulled her waist up off the bottom and entered her cunt from behind. She took me all in and bent over so she was head down and ass up with me almost standing up. 

The girls returned from passage just as we moved into the second minute of our now very deep aquatic lovemaking. One of them took Keri’s hand with me still riding her and pulled us into the passage. I was dimly conscious of the fact that time was passing but I pushed the thought down into the back of my mind. I flipped her over to enter her from the front. She looked glorious here deep underwater without a care in the world. I glanced at my timer and saw that it was almost 11:00 o’clock. Time to get to the surface for one last breath and to prepare for my impending drowning. 

Chapter 15: Resolution 

I felt the water flow around us change a bit and I glanced back down the passage to the vertical shaft. Where there was once an opening, there was now a stout mesh gate with a lock hanging on the outside. I saw the legs of two very naughty girls kicking themselves to the surface. Fear clutched my guts and I almost shouted out loud! My timer indicated that I had been underwater for three minutes but I was getting pretty desperate for air already! 

The gate was a fact and with it was the fact that I would not be returning to the surface for a much-needed breath of air for a long time. I turned back to Keri and then back to the gate. My timer showed 4 minutes elapsed time and less than one minute to go to the hour. If I drowned in the next fifty seconds, I could be a member of the one-hour club provided that I did not breathe air until midnight. 

I have never been this brave but if Keri could do it so could I! I exhaled as hard as I could and forced all of the air out of my lungs. I hung there almost coughing from the strength of that act. Holding it out, I took my granite hard cock in my right hand. With my left, I grabbed Keri under the ass and pulled her forward impaling her wide-open cunt on my shaft. Driving my cock into her as deeply as I could, I put my mouth over hers and thrust my tongue into her awaiting throat. 

I sucked in involuntarily and she satisfied me by simultaneously clamping down hard on my dick AND forcing her breathing water down my windpipe! The pain was exquisite. I tried to take a rasping gasp but more water was my only reward. The world spun and I felt light headed coupled with the fact that drowning is a very primal fear much like falling or being eaten by an animal. Keri helped me breath and I felt a little guilty that I forced her underwater to drown her first time without more compassion. 

The hour passed quickly as we made love underwater. I knew that we were going to make this a regular thing. I wondered if we could get Michelle to join us next week?
