Crush training

A BDSM trainee in a ‘Crush’ drysuit w/o inflator hose

In the photo above: A BDSM trainee is wearing a shoulder entry heavy rubber drysuit with no low pressure hose connected to the inflator port, for ‘crush’ training. You can see details of her suits neck seal and the hood she wears to keep her long hair from getting tangled in her dive gear. She is on the preparation shelf and from her suits inflated chest area it’s obvious she hasn’t completely vented her suit to get as much of the ambient air out as possible before beginning her descent. She has been coached to leave as much air in her suit as she can and still have negative buoyancy as the more air remaining in her suit the slower she will descend to aid in equalization. In a suit like this with a weight belt and no BCD her descent will be uncontrolled down to a net stretched across the diameter of the well. She will have to work on equalizing as best she can and will pick up speed as she descends because the remaining air will be compressed inside her suit. Her goal, once she reaches the net at the 100 foot (30 meters) level will be to masturbate against the rubber crotch of her suit while holding her air consumption to 1.75 cuft per minute or less. She is wearing a nylon/lycra bodyskin to minimize the effect of being pinched by the rubber folds of the suit as it compresses around her. As she gains more experience in crush diving she will wear only a bikini under the crush suit or be completely nude except for nylon booties.

Crush diving is one aspect of BDSM training that I’ve intentionally avoided. I have inadvertently been squeezed in one of my fully functioning drysuits when I accidentally vented air and it collapsed around me. But since I’m lactating it is not a good idea to compress even empty breasts after I’ve pumped much less when they are filled with milk. Not only can the folds of rubber pinch and hurt like blazes, but breast compression can cause clogged milk ducts, something I wouldn’t wish on my worst enemy.


‘Crush training’ in a collapsed drysuit: Adolph uses several old heavy rubber drysuits with no low pressure hose connected to the suits inflator fitting for crush training. He uses old suits because the deflated suits ‘squeeze’ causes an even greater need to urinate than the dive itself and the trainee is not allowed to wear a diaper to absorb her urine. Without an inflator hose and valve connected the wearer is unable to control her buoyancy with the suit and needs to wear a buoyancy control device, BCD, or have a lift bag available to be able to return to the surface on her own or needs a handler to assure her safety. No crush training student is allowed to wear a BCD and her instructor, Adolph, is her handler and he will leave her at depth to reach the surface as best she can as, among other things, her ingenuity is being tested. She is not allowed to remove her weight belt so that any positive buoyancy of the empty tank (There is none, an empty the tank is -2 lbs), the air in her mask and hood would float her to the surface. The crush diver wears a single HP steel Nitrox-Ready Worthington X8-130. The specs for that 130 cuft tank are:

*Volume: 130 cubic feet (16.0L)
* Service Pressure: 3,442 psi
* Outside Diameter: 8.0"
* Weight: 43.0 lbs (empty)
* Height: 25.5 inches* Width: 8.00 inches
* Buoyancy Empty: -2.0 lbs
* Buoyancy Full: -11.7 lbs

The trainee breathes Nitrox II (36 % oxygen) to reduce her nitrogen loading on the dive and he gives her a lift bag, but no Spare Air bottle to fill it with so she needs to watch her gas and inflate the bag with the bubble stream from the exhalations of her last few breaths of gas from her tank rather that removing her mouthpiece and pushing the purge button and she must be sure to put a foot in the ascend loop before the bag gets away from her. Her performance score is heavily dependent on how long she is able to remain at depth not how little air remains in her tank when she reaches the surface because she could intentionally purge gas w/o using it. So crush training teaches tolerance to pain and breath control under adverse conditions and requires steady nerves, all important attributes for young divers (either Domme or Sub) entering the BDSM lifestyle.

Dive-sex bottom time calculations: Typically an experienced diver/escort’s surface air consumption (SAC) rate can vary between .5 and 1.1 cu ft and during orgasm it can rise to 2.5 cuft/min or more. For dive-sex training we assume an average of 2.25 cuft/min. If we assume a surface air consumption rate (SAC) for penetrative dive-sex of 2.25 cuft/min x 5 min = 11.25 cuft on the surface.

Crush training bottom time: For Crush training (with masturbation to orgasm) we are estimating an average of 1.75 cuft/min X 5 min = 8.75 cuft on the surface. At 100 fsw (4 ATA) 8.75 cuft x 4 ATA = 35 cuft divided into the tank capacity 130 cuft = 3.7. To get bottom time in minutes: 3.7x5 = 18.5 minutes and that is w/o any rock bottom time air for ascent and deco so the tank will be empty in about 18 minutes +/- depending on how good the divers breath control is. Breathing regular (21% O2) air if the trainee’s bottom time is no more than 20 minutes she needs no deco stop. Breathing Nitrox II (36% O2) her max bottom time is about 25 minutes bottom time before deco is required. So with good breath control she can get her minutes of bottom time into the low 20s if she can stand the pain of her suits squeeze.

Conception in a drysuit: It’s impossible to have penetrative sex with a man when the woman is in a sealed drysuit. However it’s not impossible for her to become pregnant if the woman had sex a few hours prior to diving and she is wearing the wrong style gas-guard. I’ve written about this before and it’s frustrating to me because this is an area that hasn’t been covered in women’s contraceptive training. We are seeing gas-guard problems more frequently now since the weather is warming up and The Lorelei guests are taking drysuit dive excursions to Lake Mead and Adolph has begun crush training in the well. I’ve tried talking with Adolph about alerting the guests at The Lorelei and his BDSM students who use diaphragms as gas-guards and I’ve talked to both guests at The Lorelei and his students when I meet them, but they don’t seem to understand, until it’s too late.

After Adolph tampers with a woman’s hormonal birth control all she has as backup is her gas-guard and if she remembers what it was like to be fertile before she went on hormones she may use a diaphragm for contraception and feel she is well protected. But the diaphragms that European women are most often fitted with are Milex, which is popular in the EC and will protect them in typical residential swimming pools but neither rim style, arcing or coil spring, will protect them on a dive below 30 feet. As I’ve written so often before they need a Reflexions flat spring rim diaphragm that won’t distort due to pressure during a deep dive and it’s frustrating to try and help and get rebuffed and then I’m sought out when they are in trouble from something that could have been easily avoided by using the proper protective equipment.

So there they are typically having sex in their suites or in ballet class the morning of a deep dive and with fresh semen still in their vaginas are sealed into a drysuit and descend deeper than 30 feet either on an excursion to Lake Mead or in The Well during crush training. The women use no spermicide since they are protected by the pill - so they think – and therefore are in the habit of wearing their gas-guards dry (w/o spermicide) and rim of the diaphragm they are wearing distorts, leaks and semen is suckled into the dome and sperm swim into the diver’s cervix. By examining the fluid collected in the dome when a woman removes her gas-guard she can get an idea if it leaked and she is in trouble or not. But, most of the women haven’t been taught to examine the fluid in their diaphragms immediately upon remove. The fluid can be a mixture of liquefied spermicide, fertile cervical mucus (FCM), natural lube from the anterior vaginal wall, or semen that leaked past the rim. If they were familiar with the differences and something looked suspicious they could take ella right away, but even with the ones who suspect many are reluctant to take EC hoping that they are safe and that none of the fluid was semen leakage and two weeks later they miss their periods and test positive for hCG.

Drysuit neck seals

Drysuit neck seals and buoyancy: Most women rubber fetish divers who wear drysuits don’t use a buoyancy control device (BCD). That means that: 1) They have to be experienced enough with the drysuit they are diving that they can control their buoyancy with it. 2) That w/o a BCD by decreasing the air in their drysuit they can show off their figures and experience arousal from the suits squeeze compressing their bodies and 3) They are at risk of having an uncontrolled descent if their neck seal fails. An uncontrolled descent can often be fatal to a diver even in a shallow pool if she is diving solo and has no way to get off the bottom. I always carry a small lift-bag in a pouch on the waist strap of my tank harness in case I find myself in that situation.

It’s a bit other-worldly to be attacked while diving, especially while wearing a drysuit because unlike wearing a wetsuit when her drysuit is being used for buoyancy control a diver is a much larger and far more vulnerable target. In most dive films or TV programs showing underwater fights a diver almost always has her air hose cut. I’ve been attacked so often that I have my air hoses armored now which in the case of my twin-hose Mistral the titanium mesh armored hoses actually helps give the hoses neutral buoyancy rather than the air filled hoses tugging at my mouthpiece and causing me to exert effort to keep my head level rather than my chin being pulled toward the surface from the lift of the air in the hoses.

All three times I’ve been attacked my attacker went for my air hose. In a wetsuit that’s a good strategy, but if I’m attacking a diver in a drysuit I like to go for the neck seal. It’s a large soft target and if you can slit an opponent’s neck seal at the very least you have flooded his or her suit and weighted her down. If s/he is wearing a BCD and can still control her buoyancy my next slash is the air bladder of her BCD. If she isn’t wearing a BCD then slashing an opponent’s neck seal probably caused her to lose buoyancy – even if she drops her weights - and begin an uncontrolled descent. An uncontrolled descent in open water is almost always fatal. If I can I like to pull my opponents fins off as well, which limits her ability (regardless of her strength) to fin her way to the surface while trapped in a flooded drysuit. If my opponent reaches the bottom alive it’s just a matter of time until s/he runs out of air. If it’s a woman and I can reach her body I like to check her vagina to see what upper reproductive tract protection she was using. Before disposing of the body I’ll harvest any of her equipment that I want. I don’t think I’m particularly vindictive, but if my attacker has really upset me or I need something for DNA verification I’ll harvest her ovaries or his testicles. Disposal is a lot easier in open water because if you slit the belly so it won’t bloat and float as it rots a diver can disappear w/o a trace.

Cycle status: I’m CD11 today and fertile with the transparent silicone rubber membrane of an Oves sucking on my cervix collecting my fertile cervical fluid. I feel so safe and confident when wearing an Oves. The week I’m fertile I’m always more eager for sex with a man and for some reason I seem to be more easily aroused when it’s raining as it is this morning. It’s raining here in town but it is snowing in the hills to the west of us and to the south in Henderson.

Ben Wa balls and IUDs: A reader asks if its safe to use Ben Wa balls with an IUD. If the IUD is a GyneFix frameless IUD implant the answer is yes it is quite safe. However, if the IUD is one with a frame, such as a ParaGard or a Mirena which have strings that protrude from the cervix and the Ben Wa balls are connected together as they commonly are it is possible that the strings of the IUD could tangle in the material connecting the balls and pull the IUD out of the wearer’s uterus. Ben Wa balls that are not connected so there is no possibility of the IUD strings tangling with them can be used safely while wearing a framed IUD.

IUDs and dive-sex: While I’m discussing IUDs, I’ve mentioned this before but it’s worth repeating for my women readers. We had a woman auditioning for a seat in our escort training class who had her ParaGard pulled out when the strings stuck to the dome of her gas guard. Gas guards are mandatory for dive-sex to minimize the possibility of a gas embolism so we advise all women with framed IUDs who want to train for or have dive-sex to switch to a frameless GyneFix implant or have the strings cut off her framed IUD so it won’t interfere with her gas guard. Ideally a framed IUD should be replaced by a GyneFix if possible because the uterine cramps caused by an intense orgasm of the sort usually experienced during dive-sex will often bend the frame of a ParaGard or Mirena causing it to either embed in the uterine wall or be expelled. No woman is accepted for our escort training classes if she has a framed IUD inserted.

The murder of a Pool-Chick

Zip-ties make great flexi-cuffs

A friend drowns: She was a lovely 24 y/o brunette and an accomplished dancer. She was a bit curvier than the traditional Balanchine body, but she was very good at maximizing the return on her assets. She wasn’t getting paid what she thought she was worth as a dancer and she saw her beauty as a depreciating asset which she needed to at least price at the market rate so she became an independent businesswoman. Ever since September of 2008 when Wall Street melted down the demand for beautiful and talented women for fantasy encounters has gone through the roof, and the demand for elite talent has far exceeded supply. Adventuresome women entered the business as Independent operators to profit from the shortage of high end fantasy escorts and the independents screening and security isn’t always the best, which may have lead to what happened last week.

Her business premises: She had set up in a secluded estate that had been foreclosed on and is now owned by a California bank. The former owners had walked away leaving the place furnished and the bank left the utilities on and is keeping the place up including pool maintenance while a local real estate company is showing it to prospective buyers. All she used was a bedroom and the enclosed pool and kept her usage undetected hiding her diving gear among the sports equipment the former owners left. She had an arrangement with a friend at the realtors so she knew when the house was to be shown so she could make certain there was no sign of her activity. She had come to me when she set up out there and I advised her on what she would need. The pool is conventional with a dive well at the deep end of only 15 feet. But that’s plenty of room if a client doesn’t want a three atmosphere encounter.

Her equipment: Because the place was being shown she couldn’t leave a vaginal muscle trainer or tether anchors on the pool bottom so I suggested she use a drain clip to clip a set of tethers to the grill over the drain at the bottom of the dive-well and use a BCD to hold her off the bottom but she thought a BCD would just get in the way of a more intimate encounter with a client. So then I suggested she wear weighted pool-pointes. Pool pointes are silicone pointe shoes made using a pair of the woman’s actual pointes as a pattern and they are usually made with polymer shanks and neutral buoyancy and a good pair will support you en pointe when out of the water. The ribbons are one single length looped through grommets and a slot under the insole so ribbons can be easily replaced w/o sewing. The platforms of the blocks can be fitted with a threaded adaptor that allows lead weights to be screwed to the platforms to hold the wearer on the bottom for walking around or stability during a dive-sex encounter and that is what she decided to use and did so with considerable success. At least that’s what she said. She had the lead platform-weights coated with silicone rubber (which is a standard option) so she wouldn’t mark the bottom of the pool with lead if she was dragged along the bottom. I suggested again that she wear a buoyancy control vest but she said the pool was shallow and the SCUBA equipment she was using was positively buoyant when the tank was low so she could drop her weight belt and the pool pointes were held on with Velcro fasteners so they could be quickly unfastened and the weighted pointe-shoes dropped if necessary. She also wasn’t using a dive computer because, she said, of the short duration shallow dives. I asked what about repetitive dives and she said she wasn’t doing more than two a day so thought she would be safe. I wasn’t at all sure. What if something changed and she needed to know if it was safe for her to dive a third time that day? But she smiled and said she would be fine.

Her laptop showed she had a morning encounter scheduled. Her air supplier, the guy has a portable compressor and comes to fill her empty oxygen tanks, found her that afternoon on the bottom of the pool.

Her arms had been spread and her wrists were zip-tied to an air tank dolly which had been tossed into the pool and her air hose had been cut.

Even with the light weight of the aluminum dolly she couldn’t get off the bottom because she had no BCD and couldn’t drop her weight belt and weighted shoes. Not that a BCD would have done her any good as her attacker would certainly have slashed its air bladder.

Her last minute or two w/o air must have been terrifying!

The ME said: She was wearing a strapless FemCap for protection and that the semen inside her had been there about as long as she had been dead, so her killer either got off in her just before he killed her or just afterward. Or, there was another person involved. There were raw spots on her hips where her thong cut into her as it was being ripped off but that might just have been rough sex.

Motive: It’s not clear to me why she was killed and killed that way. Her killer, it was almost certainly a man, and perhaps someone she knew because there were no real signs of a struggle, could just as easily have shut off the air from her tank. It was planned certainly but was her client her killer? That seems unlikely to me because he would have to be pretty stupid to leave his DNA inside his victim, but you never know. I’m thinking her death was a professional hit, done by cutting her hose to send a message. Dive sex is a premium service and the guys I talked to said she was very good at it. Perhaps the elite independent girls who have started cream skimming the high end services during the talent shortage are seen as a threat and someone is trying to scare them off. Being a pool-chick in Vegas can be dangerous.
