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.


  1. It looks like you had a fun time Tuesday night in your new gear. I was wondering if you would be able to put enough weights on your pool pointes to give you enough bottom weight to use them instead of dive boots? Knowing you, I think if I were the client you'll be seeing, I'd rather see you in pool pointes than dive boots.

  2. You are right! Knowing now how the KMH-16 handles during an underwater encounter I will use 5 lb platform weights on my pool pointes which should be all I’ll need for vertical stability.
