Flooding a Kirby Morgan


Use a Milex gas guard – when only the best will do

Flooding a Kirby Morgan: Returning readers remember that I changed the neoprene neck dam in Kim’s KMH-16 for one that fit me when I harvested it after her suffocation (Or should that be drowning?) when she died from fluid in her lungs caused by breathing chlorine gas maliciously pumped into her helmet. [For more about that see my entry for November 17, 2009, Gassed and suffocated.] When she was found we think she had been on the bottom with pressurized chlorine gas in her helmet for more than three hours. The Divemaster said the neck dam would have had to be replaced anyway because chlorine gas reacts with neoprene to rapidly destroy it so the one Kim was using was no longer safe. The neck dam is the only thing in the helmet that is neoprene, though latex neck dams are an available option. Neoprene is warmer and usually lasts longer so I think neoprene is pretty standard.

I’m mentioning this because the Divemaster put the old chlorine impregnated neck dam in the trash when she replaced it with a new one in my size and certified Kim’s old helmet safe and ready to dive. And now there has been an incident with the failure of a KMH-16 neoprene neck dam. From what I understand it appears to have been caused by deterioration from a corrosive chemical. We think what happened was that a 17 y/o boy who was into diving as a hobby found the neck dam while dumpster diving the casino’s trash and took it home to replace one that had torn in a secondhand KMH he was diving. Security had caught him in the dumpsters several times and escorted him off the property so he was known to them. He was on the bottom of the 15 ft dive well of his parents pool with his girlfriend when his surface supplied air shut off. He should have been ok long enough to be able to get to the surface if the safety features of his helmet had been working properly, but the gas supply non-return valve failed (inspection showed later that there was grit holding the valve open.) and the helmet lost gas pressure and the resulting ‘squeeze’ put such a strain on the deteriorated neoprene of the neck dam that it tore and the helmet flooded. This happened very quickly, our Divemaster thinks it took less than a minute. The squeeze that occurred before the flooding compressed the stiff deteriorated neoprene of the neck sheath causing it to corrugate and crush the small bones and vertebra in his neck as the water pressure pushed the neck dam toward the top of the helmet. If he was still alive when the neck dam ruptured he drowned. He didn’t have time to unfasten his weighted dive boots and attempt an emergency ascent. The girl he was having dive-sex with at the time is safe. She was wearing a single hose regulator SCUBA set so wasn’t affected by the surface supply air failure, but she freaked out and is in therapy. We don’t know for sure that he was using the weakened neck dam from Kim’s helmet, but the coincidence is striking. In hindsight we probably should have slit the chlorine deteriorated neck dam to make it obviously unusable before throwing it in the trash. Dive fatalities usually occur from a series of equipment failures or mistakes rather than one major one. The failure of the non-return valve was major and probably was fatal, but the rupture of the neck dam from the stress of being pushed into the helmet immediately afterward sealed his fate. Life support gear like diving equipment should be inspected and have routine maintenance like lubrication and replacing gaskets and seals performed at least once a year or more frequently if used in harsh environments. The boy’s helmet hadn’t been properly maintained and certified as safe since the boy bought it several years ago.

Thanksgiving plans: I am having my friends over for dinner and to watch the parade and sports. I’ve invited Taryn, Cyndi, Anya, Shelly, Marie-Claude, DianĂ©, Chris, Chuck, Pirate and Robin, Peter and Jacques and perhaps another man. Shelly and Marie-Claude need partners for holiday sex and I’m not sure who they will be yet. Perhaps Robin will be with Marie-Claude they make a lovely couple. I’ve talked with Jacques and emotionally he has moved on, to me I hope, and said he doesn’t mind Marie-Claude being in someone else’s bed and he seemed sincere when he said it, but if he is now interested in me as a recreational sex partner he couldn’t possibly have given me a different answer. Given how shabbily Shelly was treated by her new husband Rubberstud before he and a paramour disappeared off a cruise ship in the Caribbean she is taking a while to begin to put herself into the dating scene again. But as a young widow with emotional and physical needs she has recently been looking for a bed mate and I hope she or we can find her one by Thanksgiving. If it isn’t love by then infatuation or just raw lust will do. The girls are all bringing their Milex gas guards as there will be group dive-sex.

Barbers, beards and breasts: For long weekends or holidays with a lot of male guests I hire a barber, one who is an expert with a straight razor. It is very painful for a woman to have a lover caress her breasts with sandpaper beard stubble. That just tears up the sensitive tissue of a girl’s areolae horribly. So the easiest way around that is to have a barber on site who can give the men in the party a close shave twice or sometimes more each day. My women guests think that’s a marvelous idea!

Heather and Alison: I had a comment from a friend and returning reader about the women in my November 16, 2009 post ‘Brotherly love and incest’. Bryan thinks it doesn’t seem right that Heather wants her step-daughter, Alison, to become a Sub in the D/S subculture. I can understand his skepticism. However, in my experience sometimes you can't tell which way a person will swing Domme or Sub. I think Heather can go either way just as I can, depending on the situation. I think Heather wants Alison under her control so she can steer her away from her psychological need for sex with her father who is Heather’s new husband. Bringing Alison into the D/S as a sub will strengthen her grip on Alison's vulnerabilities. And, just because Alison is introduced into the D/S lifestyle as a Sub doesn’t necessarily mean that she will always be a Sub. I was introduced to BDSM as a Sub and accepted that as an entry position and learned the rules of the subculture from my master. The master who trains you has a huge influence on how a girl turns out and I’ve seen some gorgeous and talented girls broken by extremely sadistic masters who gave no praise or encouragement regardless of how well the girl performed. So Heather’s choice of Master for her step-daughter or who gets Alison if she is auctioned at a Sub-sale is crucial.

I’m hoping that Heather doesn’t decide to enter Alison in a Sub-auction. She doesn’t need the money and the likelihood of Alison being taken out of town by the winning bidder is pretty high as Vegas auctions have some of the highest quality female Subs available at auction in the U.S. If all she wants is just to steer Alison into the sub-culture she should be able to do that with a local master who wants a lovely new Sub to dominate and will give her a 2-year contract.

Diving a Kirby Morgan

Fallout from the chlorine problem: In my post for November 17, 2009 “Gassed and suffocated” We found someone had tampered with the air compressor that provided air for the surface air supply fed divers. Only one escort was training at the time and she died from chlorine in her air supply. The entire surface feed air compressor and reservoir as well s the air intake and distribution system have been replaced. It was a super rush job and the compressor and reservoir were up-graded at the same time. The engine is larger, quieter, uses less power and is in what we hope will be a tamper proof room.

In a related matter I bought another Kirby Morgan helmet, a new top of the line SuperLite-17B for the casino so I can keep the KMH-16 that I harvested from Kim who died from breathing chlorine gas while wearing it. Now the 'death helmet' is officially mine, not that anyone else wanted to wear it, but replacing it with a similar but newer diving helmet removes the potential for complaints that I would take company equipment for personal use.

Diving my KM-16 ‘death helmet’: So, last night Robin was my partner for a rehearsal with me in the Kirby Martin helmet in which Kim, the escort, drowned in her own fluids when someone contaminated her air with chlorine gas. I had worn a KM helmet a year or so ago so I knew that at about 27 pounds it takes some getting used to, to get into and out of. I can see why Kim was practicing as a girl likes to look as though she’s always in control and not struggling with her life support equipment during an encounter. The air hose tends to pull so I always ensured I had a large loop of hose beside me so I could move around w/o the helmet being pulled to my right the direction the hose feeds from. The client is big on a girl dressing herself so I wanted to see how much I remembered about putting on a KM helmet with Robin there to help if needed. It turns out Robin is experienced with the KM SuperLite-17B that he used while working part time as a commercial diver while he was in Asia. Dressing in a KMH isn’t quite as simple as pulling on a neoprene hood fitting on a face mask, turning on the air, putting a reg in your mouth and disappearing below the surface.

Dressing in a KMH: The helmet consists of two pieces: the neck dam-yoke and the helmet. The diver slips on the neck dam with the attached yoke and tightens the neck seal. The neck dam- yoke assembly is sealed around the diver’s neck and is what the helmet sits on. I needed a different size neck dam than Kim was wearing so it would seal properly. Then after the neck dam- yoke is in place a head cushion, which looks something like a heavily padded flight helmet, is put on to protect against bumping inside the helmet. Then the KM helmet is lowered over the diver’s head and seated on the neck dam yoke assembly and neck clamp is slipped onto the helmet and locked. The locking system seals the neck dam to the helmet and also secures the front of the yoke. For a detailed view of the neck dam-yoke and the locking clamps that hold the helmet in place see the image at the top of this entry.

The KM helmet is pretty heavy out of the water but submerged it’s about at neutral buoyancy with any residual weight evenly balanced on my shoulders across the heavily padded neoprene neck dam. I have the weights adjusted for fresh water diving where less weight is needed. One feature I love about a KMH is the valve that puts a steady flow of air across the face port to prevent fogging. With a face mask it’s always such a bother when the face plate fogs during orgasm. The chlorine smell in the helmet isn’t all that noticeable and while I’ve felt Kim’s presence, especially when Robin was ramping me up fingering my clit. I wonder if that was one of her fave things. I’m not going to try and force things. If she wants to contact me she will. In the meantime her aura seemed friendly enough, not like in some equipment I’ve harvested.

Since I had worn a KMH before it was just getting used to the sequential steps of getting it on and off again. Robin said that the client was absolutely right to want to watch me dress in the helmet because he too thought seeing a woman dress herself in life support equipment in which she was going to have an encounter which could lead to the creation of new life while in a hostile environment was extremely erotic! Men! That was a bit more profound… in a creepy fetishistic way… than I expected! Go figure! I had been going over the KMH by holding the parts, especially the pieces of the neck dam-yoke assembly and remembering how they fit together and how the locking clamps work. So when it came time to actually put on the helmet I went slowly but confidently and everything fit and locked together just as it should. I had already fastened my feet into a pair of canvas and lead diver’s boots with 15 lbs of lead in the sole of each one. The boots were to give me some weight on the bottom of the pool because I wouldn’t be wearing a weight belt and I didn’t want to struggle to stay on the bottom or take a chance of somehow becoming inverted and not being able to regain a head-up position. I didn’t think that was likely, but I wasn’t going to chance it even with Robin there and with the helmet weights adjusted for neutral buoyancy.

The dive: Then Robin helped me into the pool. We were using the small training pool at my place that at the deep end is only 15 feet. It has a gentle slope with a textured gripping surface so that a bottom diver in a heavy a suit can walk in to and out of the water with no trouble. Had we used a training pool at the casino we would have had to use a lift to get me in and out of the water as the bottom slopes are far too steep to walk in and out in heavy dive dress, even if that’s only 30 lbs of weighted boots, a KMH and a bikini. Knowing I was probably going to use the surface supply unit at my place I had the techs who replaced the casino surface supply equipment service my unit as well so I was good to go. In the desert we have to be very careful that the air intake to the compressor is triple filtered to get sand and powdery grit out of it that would clog breathing equipment. Robin wore a standard SCUBA set with a single hose reg. I had 100 feet of hose coiled on the pool edge and carried a loop or two over my arm as we walked slowly down the slope to the 15 ft. dive-well. While we walked I used the nose block to equalize the pressure in my ears as we descended. I think the one thing I really don’t like is that when used with a surface supply and the umbilical is taunt it exerts a pull to the right on the diver. To eliminate that pull I put enough slack in the hose that a few feet were lying on the bottom. That works well enough for recreational dives in a controlled environment like a pool, but on commercial dives I could see that as a potential problem for a small diver, like me.

The Encounter: When we got to the bottom we were both already highly aroused. I think it was the anticipation that had us both so excited! I was in a hip-tied string thong and he could have just pushed the vulva cup to one side and taken me w/o removing it, but he tugged at the bows on my hips and my thong came away in his hand. When I bent over so he could enter me from the rear I was glad to see that there was no strain on the neck dam and yoke that kept the helmet positioned correctly and that was the case as well when I was on my back with him taking me in a modified missionary position regardless of my or the helmets orientation. I know I’ve mentioned this before but I really like the steady flow valve that puts air across the face port. It not only prevents fogging but it’s cooling as well which is a great feature. It was a magical encounter! We took our time. He took me three times in 45 minutes and while he recycled I did limbering up exercises and unfastened and removed the weighted boots and put on a pair of silicone rubber slippers to see how buoyant I would be in just the helmet. For every inhalation I became positively buoyant and started floating toward the surface but was held near the bottom by the weight of my umbilical. There is a comm. Link in the umbilical as well as the air pipe in it so that might give it a bit more weight. When he took me the third time, again from behind where he can go the deepest, I could feel his thrusts through the thin silicone membrane of my gas guard as he rammed my cervix. He took me to such an amazing screaming cervical orgasm that it left me rubber legged as I struggled to put on my dive boots again before we walked up the ramp and out of the pool. On my walk out of the pool I carried my thong in my hand. I really like my ‘new’ KM-16 and think I will be able to exceed his expectations when I meet Kim’s last client.
