Prentif crush depth side effects.

The cervix on cycle day 7, just past menses

The photo: taken on CD7 it shows a healthy symmetrical cervix perfectly shaped for the effective use of a Prentif cavity rim cervical cap.

Dive-sex and a Prentif Death Rubber: I was fortunate to be able to recently check off another of the cervical barriers (in my size) I harvest from the bodies of women who die during a sexual encounter. Returning readers will remember I call the protective rubber clothing, shoes and devices harvested from those women ‘death rubber.’ I especially love to wear a death rubber cervical barrier. Because it provided intimate protection to its former owner I feel it contains far more of the Chi of the woman who was wearing it when she died. The dead woman’s Chi combined with my own increases my libido amazingly.

I was lucky to happen upon a 23 y/o woman, a well-bred Brit-Chick rubberist with a plumy Berkshire accent, who had a Prentif. Lucky because Prentif have been discontinued for more than seven years and amazingly it was a 25mm which is my size! Actually, the woman from whom I harvested my Prentif death rubber found me since she was a guest at The Lorelei, Adolph’s spa in the hills outside town. She was interested in rough dive-sex and I had been recommended to her as a fitter for a barrier to be use as a gas-guard/flood insurance, because she wanted to experience a rough underwater sexual encounter. For contraception she was ‘on the jab’ as she called it, the Depo-subQ Provera 104 injection so she had no concern about an unplanned pregnancy.

I gave her a thorough pelvic and fit her with a Reflexions 75mm flat spring latex diaphragm. After her diaphragm fitting she asked if I thought she was a good candidate for a Prentif cavity rim cervical cap because she had purchased a 25mm from a midwifery supply store. I asked how she had determined the size and she said she bought the smallest size they had. Sigh! During her pelvic I saw she had a lovely smooth and symmetrical cervix which would be ideal for wearing a Prentif so we broke the seal on the box took the 25mm cap out of its case and I inserted it slipping it on to her cervix and screwed it down tight. The cavity in the rim established a strong suction on the cervical wall gripping her cervix and the dome dimpled, as it should, indicating there was a strong vacuum in the dome. She was so lucky! It fit perfectly! She was delighted because she liked the idea of the dome being an extension of her cervix making it easier for a partner to ram, which as a sexual masochist she enjoyed. I knew exactly what she meant as I’m that way myself! I cautioned her that if she wanted her partner to ram the dome she should be sure to turn the tab on the shoulder of the rim so that it faced her posterior fornix so it wouldn’t hurt her partner and had her reach in while pushing down and turn the tab to the back herself.

Diving the Prentif: Some women can take more pressure on their cervix than others and there is no way to know which is which until they pressure test a cervical cap either on a dive or preferably in a hyperbaric chamber, but the HC option is unlikely because there are almost no hyperbaric facilities available for that sort of testing. Some women seem to delight in having the cervix gripped tightly while others can’t stand even having a Prentif’s cavity rim sucking on the base of their cervix. So when I fitted my patient with the Prentif - before I’d done my hyperbaric chamber research about diving cervical caps and found the crush depth of a Prentif was approximately 30 feet - I already had my suspicions that if the cap wasn’t forced off the cervix when the dome was compressed by the increased pressure it would squeeze her cervix so tightly she’d probably be unable to function from pain and nausea. So I cautioned her not to go too deep because there is a tipping point where the discomfort seems manageable or perhaps even enjoyable at depth and then a few feet deeper the pain suddenly becomes unbearable. I’ve tried taking 800mg of ibuprofen before a HC test dive to see if it upped my pain threshold and it did marginally, but only enough to give me time to try to ascend to get away from the pain if I’d gone too far. I’ve found that for me other than the pain, which I enjoy, there is no warning. One minute I’m doing fine. The next I’m having terrible cramps and vomiting, which when diving can be fatal.

An opportunity: So, a few days later I got a call from Adolph. A guest at The Lorelei has had an incident during a BDSM dive encounter he said and he needs my help tidying up loose ends. I got to the Spa to find the guest still at the bottom of her suites encounter pool. It was one of the new suites with the 40 ft deep pools. She was dressed all in black; a rubber catsuit, weighted pool-pointes, hood, gloves and a FFM with a short tank so it wouldn’t impair her partner’s access when penetrating her from the rear. She was wearing a buoyancy compensator and when I got there the body was in the fetal position on its side with it’s legs drawn up to the chest in a locked metal cage on the bottom with a cable and hook connected to the top that ran to a winch suspended above the surface of the pool.

It was obvious to me that Adolph had been the partner of the woman in the cage when or shortly before she got in trouble. He had often fantasized to me about that sort of dungeon set-up, but I hadn’t known he had actually built it. He said they had sex in the cage at15 feet below the surface and everything was fine then he had left her to raise the cage and the winch gearbox failed and the cage went all the way to the bottom. He wanted me to go down and retrieve the body. I just laughed and said he better call an mechanic because there was no way I was going in that cage underwater unless he was in a straight jacket and sedated. He just smiled and said I knew him too well then took the remote out of his pocket and raised the cage and swung it on to the pool deck.

The body: She was totally encased in rubber except for her vulva that was showing through the open relief zipper. I hit the quick release latches on her FFM spider and pulled off her mask. The oral nasal unit was filled with vomit and the stench of gastric juices nearly made me gag. She has suffocated, drowning in her own vomit. Her face was twisted in fear and pain, but I still recognized her as my 25mm Prentif patient of a few days earlier. Her wrists had been restrained with zip-ties and fastened to the bottom strap that held her air tank on its backboard. At first I didn’t understand why her hands had been tied and then I realized it was so she couldn’t reach the Prentif I was almost certain she was wearing. It was just the sort of diabolical thing Adolph would do; place a woman he just had sex with in a situation where as her depth increased so did her pain. Was it an accident and he hadn’t intended to kill her just to apply exquisite torture using her own reproductive tract? Or, did he want to see what happened regardless of the consequences?

Benefit analysis: I am certain that the HD video of the Prentif-girl encounter will be a dive snuff-porn best seller for rubberiest as well as dive-sex fetishists in Europe and Asia. I did my usual vaginal search of the corpse and found she was indeed wearing the 25mm Prentif I’d first screwed onto her cervix. It took me several minutes to glove-up push her uterus down where I could easily reach her cervix and get two fingers under the rim to break the vacuum and pop it off her cervix. It was full of blood and pieces of endometrium, but hadn’t come loose. The cap itself seemed to have survived in good condition. I could hardly wait to try wearing it myself! I cleaned it well and sterilized it by soaking it in alcohol then checked it closely again to make certain there was no damage to the rubber so I have my first Prentif death rubber! I’m wearing it as I write this and I like to think the previous owner has contributed to this entry. I realize there are severe depth limitations to diving a Prentif, but the surge in my sex drive from her Chi make it a must-wear to residential pool parties where pools used for encounters are no more than 15 feet deep.

Adolph says that the woman had left an Advanced Medical Directive and a will (she told him she had no family) to the affect that if something happened to her while training at the spa her body should be cremated and her ashes scattered in the desert. The coroner ruled she ‘died by misadventure’ when it was found from her medical records that she had a known history of seizures, which she hadn’t listed on the required medical questionnaire at The Lorelei before being allowed to dive nor had her seizure history been on the history she gave our clinic before I fit her barriers. Personally, I’m convinced that the pain got continually worse from the dome squeezing her cervix as she sank below a depth of 25 feet until it caused uterine cramping so severe that she vomited as a side effect of diving her Prentif too deep.

Diving cervical caps while fertile

Clockwise from the top: FemCap, Oves & Prentif cervical caps

Self fitting cervical caps: Before I begin, a warning to do-it-yourselfers, self fitting of cervical caps is not a good idea and should be avoided if you plan to use one for contraception or flood insurance. That’s because:

• The FemCap maker says that a woman’s OB history is the primary indicator of her cap size. However, that is not always the case and in addition a severely anteverted or retroverted cervix will not allow the brim to seal properly against the vaginal walls and cause the cap to fail and the male partner to hit the brim. FemCap was approved for a continuous wearing interval of 48 hours.
• Self fitting a Prentif can be even more difficult because it suctions on the wall of the cervix itself and it comes in only 4 sizes so a significant percentage of women who wanted Prentif couldn’t be fitted. The wall of the cervix must be symmetrical and smooth so that the cavity rim can seal tightly around the entire circumference to develop the strong suction that holds the cap in place. Prentif hasn’t been produced for at least 5 years so availability is extremely limited and experienced fitters are very difficult to find. Prentif was approved for a continuous wearing interval of 48 hours.
• Oves, when it was available, over-the-counter in the UK, was the easiest to self-fit because you could buy a fitting kit with one of each of the three sizes and the dome was so soft that a woman could fairly easily fit herself, but it still required having a smooth cervical wall so the toothed rim could grip the cervix tightly. The dome membrane clings to the cervix by surface tension. Oves was approved in the EU for a continuous wearing interval of 72 hours.

Diving cervical caps while fertile: As I write this I’m CD3 and bleeding heavily so I’m wearing a Milex Omniflex for flow control for the five or six days of my period, unless I want menstrual sex, then I will switch to a flat spring so I can more fully enjoy the encounter and to minimize the possibility of under-thrusting. Returning readers know that my primary cervical barrier for contraception and flood insurance is an Oves cervical cap, but cervical caps can’t be worn effectively during menses.

Before I dive I always remove, empty, clean and reinsert my Oves cap so that the dome will be empty of cervical secretions when I enter the water. That way, when pressure collapses the dome, it won’t force the secretions out breaking the seal and cause the Oves to displace off my cervix. It’s necessary to stay well hydrated and I empty my bladder before diving because diving is very dehydrating. Water pressure squeezes fluids out of body tissues and into the kidneys. Even after emptying before entering the water the pressure will invariably cause me to need to urinate if I’m underwater for 30 minutes or longer and I end up peeing in the pool anyway. Severe dehydration can lead to loss of stamina, overheating and low blood pressure during a dive so going into a dive well hydrated is very important.

On the plus side for women divers dehydration due to diving minimizes menstrual flow and also fertile cervical mucus which is a good thing for divers wearing cervical caps for protection. From my own experience and discussions with other women divers the reduced uterine/cervical secretions while underwater seem to be a common side effect of diving for those of us of reproductive age. Emptying my cervical cap before each dive has worked well for me as I’ve never had a cap displace during an underwater sexual encounter. When I’m not fertile or menstrual and will be underwater for long intervals I take a 0.1mg tablet of Minirin (desmopressin acetate) an hour before I dive and then I don’t have to pee for about eight hours. It can react with antidepressants and pain meds but I’m not on any and have had no side effects with such a low dose.

The question: I had wondered what it felt like to have a cap displace, or float off my cervix, but until the multiplace hyperbaric chamber recently became available at Adolph’s training facility [I wrote about it in my post for July 1, 2012 entitled: The vacuum sealed cervix] I had no safe and effective way to see for myself what would happen if I dived my caps with spermicide and copious cervical secretions in the domes. So several weeks ago, when I was fertile this past cycle, I experimented with my cervical caps; 26mm silicone FemCap, 25mm latex Prentif and 26mm silicone Oves to see what happened when the domes collapsed from squeeze while filled with secretions. I wore each on a test dive in the hyperbaric chamber to simulate dives to 66 feet, three atmospheres (ATA), and how much that affected any thrust buffering the domes provide. The results are below.

A silicone rubber FemCap


The FemCap full dome test dive: After wearing my 26mm FemCap for two days, with a ¼ tsp of spermicide in the dome (as called for) and 36 hours of fertile cervical mucus (FCM) discharge in the dome I simulated a 66 foot dive in the hyperbaric chamber. Before proceeding I checked that the cap was properly in place by squatting and pressing upward on the strap and dome for more than 10 seconds to make sure the cap was correctly positioned with strong suction.

Then while lying on my back on one of the beds as the pressure increased and I worked to equalize the pressure in my ears and sinuses I inserted two fingers in my vagina to feel any changes in the dome due to squeeze. As I expected the pressure forced my cervix deeper into the dome then the dome collapsed filling any remaining void between the top and my cervix. At 15 feet it wasn’t painful just a lot of pressure, but as I passed the 2 atmosphere depth, 33 ft., the pressure became very uncomfortable then disappeared entirely as I felt the spermicidal gel and fertile cervical mucus gushing out between the brim and my vaginal walls as the cap was floated off my cervix. It was just as I thought; as the cervix fills the dome spermicide and cervical secretions were squeezed out by the pressure breaking the seal and dislodging the cap. A dislodged FemCap provides no contraceptive protection. Only the spermicide remains as a contraceptive barrier and any thrust buffering a properly placed FemCap can provide may disappear unless the cap is forced back on to the cervix by a thrusting penis.

A pair of 22mm latex Prentif cavity rim cervical caps:


The Prentif cavity rim cap test dive: Two days after FemCap I tested my 25mm Prentif cap. Prentif is no longer made, but was very popular in Europe where caps were available long before the Prentif was approved by the FDA 1n 1988 for use in the U.S. so there are women both in the U.S and Europe still using them.

I had applied spermicide in the dome and worn my Prentif for 36 hours while fertile so that it would have plenty of FCM in the dome before I went into the hyperbaric chamber and increased the pressure to three ATA. Again, while lying on my back on one of the beds as the pressure increased and I worked to equalize the pressure in my ears and sinuses I inserted two fingers in my vagina to feel any changes in the dome due to squeeze. As I expected the pressure forced my cervix deeper into the dome then the dome collapsed filling any remaining void between the top and my cervix. But the dome of the 25mm Prentif is deeper than the FemCap dome and the pressure of having my cervix squeezed into the dome was more uncomfortable and then at 30 feet the dome collapsed, the cavity rim filled spermicide and FCM and the suction disappeared as the secretions were pushed out under the base of the rim and the Prentif floated off. It was still on my cervix, but not firmly attached and if I’d been having dive-sex with a bareback partner when it popped off I would have been in trouble and would have needed to use emergency contraception. A Prentif has some thrust buffering value. The tab on the shoulder of the cavity rim, to aid in screwing the cap on to the cervix, can hurt a partner so should be rotated to the back.

A pair of Oves silicone rubber cervical caps

The Oves cap test dive: Several hours after I removed my Prentif cap and my cervix had returned to normal I inserted my 26mm Oves cap and screwed it down tight on my cervix. At that point in my cycle I was two days before I ovulated the most fertile part of my cycle. I let the FCM build up again for 36 hours then as I had done for the other tests while lying on my back on one of the beds as the pressure increased and I worked to equalize the pressure in my ears and sinuses I inserted two fingers in my vagina to feel any changes in the dome due to squeeze. Because the dome is so thin and soft the FCM in the cap was squeezed out of the dome and the cap floated off at about 15 feet, less than the depth of an encounter pool. It sent a chill down my spine as I realized that wearing an Oves with a days worth of FCM in the dome on a dive-sex encounter would quite possibly result in an unintended pregnancy.

Not that I wear my Oves that way as I mentioned earlier, but I’d come to think of being invincible, well at least impregnable, while wearing Oves so it was sobering – though not totally unexpected - to have it proven that If I forget to empty, clean and then reinsert my Oves before a dive during my fertile days then even on a shallow dive I would be setting myself up for trouble. Fortunately for me the dehydration effect of diving plays an important role in limiting the production of FCM so that the effectiveness of diving Oves is not compromised when the dome is emptied immediately before a dive. The Oves cap provides no thrust buffering.

Conclusions: My experiments in the hyperbaric chamber show that a cervical cap with spermicide and fertile cervical mucus in the dome when worn for dive-sex will displace anywhere from a depth of 15 to 30 feet. The domes of FemCap and Prentif have a crush depth of about 30 feet at which point even when worn dry (w/o spermicide) they become extremely uncomfortable to wear and in my case would cause me to break off a dive to return to shallower water or the surface. FemCap shouldn’t be worn w/o spermicide so I think it shouldn’t be worn for dive-sex except at depths of less than 15 feet. A Prentif with an excellent fit can be effectively worn w/o spermicide so could probably be worn for a sexual encounter down to its crush depth where it becomes extremely uncomfortable at about 30 feet. Oves, emptied before a dive, can be worn to any depth because the dome is already collapsed and clinging to the cervix so there are no voids to create squeeze.

Todd Akin 6 term Republican Congressman of Missouri



“Republican Establishment Presses Todd Akin to Quit Race

Republican officials and activists pressured Missouri senate candidate Todd Akin to quit Monday and cut off millions of dollars slated for his campaign worried that his comments about abortion and ‘legitimate rape’ could ruin the GOP’s chances of controlling the Senate.”

In an interview with KTVI-TV he said: cases of pregnancy from rape are “really rare”. And, “If it’s a legitimate rape the female body has ways to try to shut that whole thing down”.

Deep thrusting and flat spring latex diaphragms

One of my 80mm latex flat spring diaphragms

The photo: The soft stretchy natural latex dome has a small triangle enclosing the size of the device in mm in raised characters in the center of the domes outer surface. The white curved and notched wand above the diaphragm is an introducer used to aid in insertion. Because the rim folds in a single plane the flat spring is ideal for use with a deep thrusting partner and is the style preferred by professional rubber-escorts because it is almost impossible to under-thrust the rim. This style diaphragm can be worn with the dome reversed so the raised lettering is on the inside if the sensation is too intense for a lover.

The Fall semester at UNLV: The Fall semester begins at UNLV on Monday August 27 and ends on Saturday December 15. Some Grad students are already returning, reestablishing housekeeping and getting their Gyn visits over with prior to resuming fetish based sexual activity while at school. The rubber-girls are more likely to come in for pelvic exams since they all want to make sure the vaginal rubber devices they wear are still in good condition and properly sized after several months of heavy use during vacation.

The candidate: Judy, a 26 y/o Ph.D. candidate in psychology, and a sorority member with an active fetish life as a rubber-chick came in for her usual 6 month pelvic and full STI panel. I worked her up and did her pap and diaphragm fit check. I had already heard of her as a doctorial candidate, but she also caught my attention in the Spring - when she was assigned to me as a new patient since her regular practitioner left the clinic - because there are so few female rubberists not to mention gorgeous and smart ones. Her vaginal muscle tone is very strong, and her pelvic dimensions (deep post-pubic vault and vaginal length) are almost identical to mine, so she wears the same size diaphragm I do, an 80mm though she is four inches taller than me. Another amazing similarity is that for vaginal toning she uses a set of .75 inch solid stainless steel balls weighing 1.0 oz. each just like I do! I thought I was the only one using solid steel balls, but obviously not, but I do plan to introduce them into the AST class I’ll be teaching to upper form students at St Lucy’s this Fall. I have seen other female patients who were a close match to me physically, but they were pure Vanilla. Judy already into the lifestyle and wanting to go further will be perfect for my purposes.

I knew Judy was an active rubberist because she and I have discussed latex catsuits and vaginal plugs and she had been wearing a silicone All-Flex for protection during rough sex, but this time I suggested she change to a flat spring latex diaphragm as latex has far better heat transfer properties and it is nearly impossible to under-thrust a flat spring rim thus making it both more comfortable and safer to wear. She has also used our search service [putting medical records on-line has made this easy] to remotely check potential sexual partners medical records for STIs, latex allergies and other possible medical problems prior to entering any sort of physical relationship, so I knew she was a player. All of which makes her an ideal candidate for an experiment I want to try to see if I can replicate in other female rubberists and their partners the pleasure I get from wearing a Reflexions latex flat spring diaphragm.

Judy’s faculty advisor had contacted me on her behalf last Spring asking if I would help guide her doctorial candidate into the lifestyle in the valley. So I was already aware she would be contacting me when she was ready and this past week she broached the subject during her semi-annual exam. The topic of her doctorial thesis will be: ‘Women as enablers in male deviant sexual behavior’. She is a Switch and can be submissive or dominant as necessary to meet her personal or research needs. She asked for my help in meeting suitable male rubberists to study their various techniques and learn what they get out of heterosexual intercourse in a D or S relationship. She plans to develop active sexual relationships with at least eighteen men over the next two years and if that sample isn’t broad enough she said she may begin hunting suitable partners in the general male population. I decided the safest thing to do would be to introduce her to the male escort trainees who are rubberists and who have been screened for STIs and mental stability so she doesn’t get her air hose cut while at the bottom of a training pool during a dive-sex encounter. There seems to be an inexhaustible supply of high quality male rubberist trainees so as long as she stays with our trainees I don’t think she will run out of suitable men and these guys have far more stamina that a pick-up from a meat market so she will have to pace herself to prevent becoming physically exhausted from research.

Most of our trainees enjoy sex with women who wear rubber (catsuits, dive gear and vaginal barriers), pointe-shoes and like rough sex which are the fetish aspects Judy is most comfortable with so far. She is a qualified open water SCUBA diver, which is good enough for dive-sex. She also attended several summer sessions at SAB and takes private ballet lessons so she may be strong enough that I can let her safely try ballet-sex in pointe shoes. We’ll see about that. Her contemplative training needs to be far enough advanced that she can compartmentalize control of her feet and legs from her sexual needs so her legs don’t collapse during orgasm while en pointe. She enjoys the discomfort of pointe shoes and deep thrusting by large men so she seems Ideal for the research I want to conduct. Since we both need different men penetrating her this will give her an ideal opportunity to meet some of the men she will be conducting intimate research with over the next few months. I never thought I’d be an advisor to a Ph.D. candidate, but of course I’m a technical resource rather than an academic advisor.


The anterior fornix and latex diaphragms: On average, the ectocervix (the part of the cervix that protrudes into the vagina) is 3 cm long and 2.5 cm wide. The 3 cm length of the anterior cervical wall and the anterior vaginal wall form a gap called the anterior fornix which along with the cervix is covered by the dome of a contraceptive diaphragm. Thus the anterior fornix is typically a 3 cm cleft into which the stretchy latex membrane of a flat spring diaphragm can be pushed by the force of a thrusting penis, assuming the shaft is long enough to reach and penetrate the anterior fornix of an aroused partner.

The latex Reflexions flat spring diaphragm is the only maker and style that allows a male to fully penetrate his partner’s anterior fornix while she is wearing it. That’s because the silicone domes of other major diaphragm makers (Ortho and Milex) aren’t elastic enough to be stretched and pushed into the depths of the cleft. The latex dome has heat transfer characteristics far superior to a silicone diaphragm so thrusting into the latex membrane of the Reflexions is almost like skin-on-skin contact. The flat spring rim of the Reflexions, which flexes in a single plane, aids in successful fornix penetration by providing a stable rim to allow stretching the dome over the cervix and deep into the cleft.

I know for a woman it sounds as though its business as usual having a partner thrust into her anterior fornix while being taken in missionary, but when using a latex Reflexions diaphragm that’s not necessarily the case. I’ve known for several years that there can be unanticipated benefits for me and my partner when I’m taken that way with him targeting my anterior fornix as the primary goal of his thrusts. When everything is just right the benefits are:

• For me: The dome stretched over the tip of my cervix as his penis thrusts into my anterior fornix puts pressure on my uterus forcing it a bit deeper slightly extending the depth of my vagina providing some thrust buffering from a long penis while moving the rim across my G-spot giving me the possibility of having both a G-spot and cervical orgasm simultaneously. 
• For him: The raised logo and size (in the center on the exterior of the dome) provide a stimulation point for my partner’s frenulum while at the same time the tautly stretched latex membrane forced into the fornix by his thrust squeezes the head of his penis multiplying the sensation of an tightened vaginal grip. My experience has been that if my partner is cut he will enjoy the increased sensation and if his size is just right I can adjust my hips and make him come regardless of how still and deep he tries to stay to avoid reaching orgasm. However, if my partner is uncut his tip is often more sensitive to the textured latex which leads to premature ejaculation or occasionally rubbing him raw. If a partner is that sensitive I can wear the diaphragm inverted, with the logo on the inside, so he feels only the smooth latex gripping his glans as he plunges into my anterior fornix.

I’ve tried to reproduce these results with other couples I’ve trained and have had limited success because experiencing the benefits is highly dependent on a great many variables such as: the length, diameter and angle of descent into the vagina of the woman’s cervix as well as the length of her vagina which determines the size of her diaphragm. And of course the girth and length of her partner’s penis are also important as he needs to be able to thrust powerfully into her anterior fornix. So I’m looking forward to working with Judy and her partners as she cycles through the men she will use to research her thesis to see if I can’t help them reach the most intense deep thrust encounters possible.

Who is the maker of these shoes?

Wall-fucked

Beavertail jacket for wall-fuck protection


The photo: The crotch of a beavertail jacket can give a novice wearer a false sense of security as she is safely protected only from being groped. Our male escorts use Hitachi Magic Wands placed just under the zipper between the twist latches to stimulate a student’s clitoris through the neoprene of her jacket. Most of women find it a surprising and extremely intense experience when they reach orgasm very quickly even if she typically has difficulty reaching orgasm. The first time I had a Hitachi wand used on me that way I was in a pair of Gepetto’s pointe boots modeling a beavertail jacket and the photographer wanted a more wanton and exhausted look and suggested my dresser use the wand on my clit right through 5mm of neoprene! I had a Penetrator plug inserted at the time and she positioned the wand right over the clit cup. It set the entire plug vibrating so the nerves around my introitus were super stimulated at the same time as my clit. I was almost instantly gasping in ecstasy! It was totally unexpected! The boots prevented me from falling off pointe and breaking an ankle, but my knees gave way and she caught me before I went over backwards. My reaction put the very look on my face the photographer wanted.

St Lucy’s ballet Summer Intensive: as a fun elective during our SI we are offering an introduction to dive-sex for students 18 or older. They must have a photo-ID (driver’s license or student ID) showing they are of or over the age of consent. Even so, some look like they are hardly 15 especially since they all have waxed pubes, which is almost a must in most good ballet schools these days and they must already be sexually active. Every student who can swim is taking the course. They are given thorough pelvic exams to ensure that their anatomy is capable of normal penile vaginal activity and I’ve fitted them all with strapless FemCaps to prevent having water forced into the uterus if the vagina floods, which it often does. I also fit the students who will have their periods during the SI with flat spring latex diaphragms for flood insurance during their periods. A FemCap will provide some thrust buffering if a partner can reach the wearer’s cervix, but a diaphragm will provide little to none. So the girls who like rough sex (we ask) are also fitted with latex diaphragms.

Beavertail protection: The students wear retro-style beavertail jackets (with twist lock fasteners) in the heated training pool and use short 80 cu ft aluminum tanks so they don’t need additional weight in the form of a weight belt that would prevent unzipping the jacket. The ‘water flush’ inherent in the twist lock fastener arrangement isn’t a problem since the jackets are being used in warm water and will be open much of the time anyway. The beavertail provides warmth, quick access and back protection both in and out of the pool when the student is being wall-fucked. The students are also fitted with pool-pointes, silicone rubber pointe shoes with polymer shanks that they can wear into the pool and to which weights can be attached on the platforms. The girls wear FFMs so they don’t have to worry about losing their mouthpiece if they scream when their cervix is hit or during orgasm and cool dry air across the lens keeps the mask from fogging.

Males in tails: The male partners for dive-sex training are escort candidates who need the training to build stamina and improve their technique. The males also wear beavertail jackets so the students have an opportunity to learn to undress a male diver. The girls love how attentive the men are and often develop a crush on the man they have been having intercourse with daily for three weeks, but for the guys it’s just an amazing summer job, which for the majority of the students is probably the most upsetting part of the course. We don’t tell them that ahead of time. All the men mount bareback even when out of the pool so the students can become accustomed to dealing with needing protection all the time having live sperm pumped into them several times a day – and learn how to Kegel most of it out – and deal confidently with coitial discharge.

We have had no unintended pregnancies during the SI this year, but it’s early yet. We test for hCG when the student arrives and then once a week and at the end of the course. Pregnancy test kits are available from student health 24/7 so if a student thinks she needs to test she can. We encourage students to have IUDs placed before arriving, but many are on the pill and so some forget to take them regularly or may take meds that interfere with the contraceptive hormones effectiveness which can lead to complications.

Wall-fucked: One of the first sexual intercourse positions a female dive-sex student learns is being taken when backed against a wall, wall-fucked, because that’s what happens most often, either against a dressing room or pool house wall or the pool wall itself. Initially she’s taken in a small encounter salle used as a dressing area where she can get used to putting on the beavertail jacket (with her partner’s help) over a thong bikini and learning to fasten the twist lock closures holding the neoprene snugly over her vulva. She learns to check that her FemCap is inserted and is covering her cervix before inserting 10 ml of silicone based DiveGel+ from a disposable applicator into her vagina. She will need the DiveGel for lubrication when penetrated underwater. Each student dives with several spare applicators of the silicone gel in case she needs additional lube while underwater. We tell the students to wear an old bikini because it’s difficult to get the lube out of a swimsuit.

Almost all of the students try at least once to be penetrated while balanced en pointe to feel the tightened grip from their clenched pelvic muscles. Wearing pool pointes for this is often ideal because the boxes will flex with the wearer’s weight when she is out of the water while the polymer shanks provide the needed support. I like watching a student get wall fucked for the first time en pointe because it’s such a transitional experience for most of them taking penetrative sex to a higher plane because it’s a far more intense encounter. Often she is shocked by her partner’s size and wonders if she can handle his length, especially when she is backed against the studio or pool house wall so she is not as deep as when entered from behind. We try to anatomically match partners with students being taken against a wall, with the larger men going with those who have shown an interest in rough sex. We are proud of the size of our male escort’s equipment most of which is 8’or longer and at least 2’ in diameter, so our students are provided an amazing penetrative experience!

I love watching a new SI student who thinks she is experienced and enjoys rough sex being entered by her trainer for the first time. He backs her against the wall, unzips and unfastens the twist locks of her beavertail, has her rise sur les pointe a la seconde and fingers her clit while fondling her breasts and sucking her nipples. Once she is wet he is gentle and enters her slowly and in stages, but when he reaches her greatest depth and still has more to give things get interesting. He can fondle her clit and get her smoking hot and she may tent a bit more, but he will usually still pound her cervix and when their pelvises slam together she is lifted off the platforms of her pointes as he puts his entire weight behind his thrusts. There are gasps and moans, mewing, whimpers and often screams as he force fits himself completely inside her while she quivers, pants and occasionally faints due to the pressure on her G-spot and cervix from his size and the uncontrolled spasming of her vaginal muscles during orgasm. It’s then that the neoprene of her jacket protects her back while her bun or high ponytail protects her head from being repeatedly and violently slammed against the wall by the force of his thrusts. In a surprisingly short time most of the students learn to like being taken that way, but occasionally there are one or two who are injured so badly that they have to withdraw from the course.

Crotch gussets

Fishnets with color coordinated silk crotch gusset


The seduction: The 19 y/o second year Dean’s List student at UNLV was preparing for her private ballet lesson. She congratulated herself on finding such an accomplished and hunky teacher, though she repeatedly chided herself for thinking of him as a sexual object, but then OMG he has an absolutely gorgeous body! And she so wanted him to be intimate with her! So in that sense he is her object of desire! And today, right on schedule, she had become fertile and was draining fertile cervical mucus into her thong, so she decided to wear her Danskin ultrasoft microfiber convertible tights, style 702, one of the ones that she had had modified with a thicker cotton pad and contrasting color crotch gussets.

Three weeks later, when I saw her at the clinic she told me how her plan had worked. She knew she was going to need the additional padding because her FCM always soaked through the standard tights crotch gussets and – though she knew she shouldn’t - she wanted to tease her teacher by calling attention to herself with the bright orange gusset. She knew he watched her with the intensity of a stalker (she had had problems with one her first year at UNLV and so she knew the signs) and she wanted to see if she could break his discipline and get him to have sex with her. It wasn’t as though there would be complications since she had a copper IUD inserted the year before at student health. She considered the modified 702s as her ‘fuck me’ tights and she intended to wear a pair of 1” diameter Pyrex Ben Wa balls during class to keep her semi-aroused so she would be wet and deep in case his need was so urgent he took her quickly with little foreplay.

From earlier classes with him she knew he became aroused if he thought she was unaware he was watching her as she did even the most mundane things; adjusting her tights, stretching and especially changing her shoes. So, as an aspiring actress, she intended to pretend to be totally unaware of the effect she was having on him - as she talked with him while changing shoes about the advantages of microfiber and convertible foot tights and why she wore both Freed and GM shoes - while she was luring him ever closer to initiating their sexual encounter.

‘Skin-tights’: After inserting a set of her 1” glass Ben Wa balls and pulling on her tights she bent over and swing her B cup breasts into a front-closure compression cup sports bra that she always trained in to prevent her high breasts from bouncing during jumps and swinging from centrifugal force during pirouettes throwing off her balance. Then looking at herself in the full length mirror in her bedroom she decided she would kick her look up another notch, to wanton, by pulling the waistband of her tights up as far as it would go and roll the top down over a belt like male dancers do. That way she could pull the stretch fabric deep into the cleavage between her glutes displaying her small tight buns individually and the front seam could be carefully stretched over her mons pubis and in the cleft between her labia to display camel toe. It was tricky getting the front seam positioned so it was between her lips and didn’t rub painfully on her clit, but she managed it. She’d only worn what she called ‘skin-tights’ twice before so it took time to get everything the way she wanted. She looked in the mirror again and thought she looked shameless! The orange fabric of the gusset formed a cleft between her labia and was obvious even when she was standing in first position. She loved it! The tights could be uncomfortable worn that way for very long, especially during ballet class where she would be sweating profusely, but she thought the look and what she hoped it would cause him to do would be worth the discomfort.

Shoe changes: She knew the brightly colored gusset was particularly noticeable as she stretched with a foot on the barre, during splits, développés and when changing her shoes. She didn’t wear slippers for barre preferring to take the entire class in toe-shoes as they keep her feet toughened and because her private teacher likes watching her move when she is wearing pointes and by changing shoes she would give him a perfect view of the orange fabric between her legs that she thinks of as accentuating her most feminine spot. So she decided she would give him two opportunities to watch her put on pointes; first by wearing slippers into the studio. That way she could let him watch how she turns back the tights convertible feet to put on toe tape and silicone gel-pads then reinsert her padded toes into the feet of the tights before slipping her feet under the heel elastics and forcing her padded toes into the blocks of a pair of old deshanked Freed Classics for barre. Then for center work she would change shoes again, this time into Gaynor Minden pointes so if she can tease him into initiating a sexual encounter she will be wearing the proper shoes in which to have ballet sex.

She put her hair up in a high ponytail with an orange scrunchie that matched the color of the 702s crotch gusset and slipped an oversized fleece sweat over her head to wear as a tunic and finally slipping on a pair of dirty white badly scuffed leather Capezio slippers for the drive. As she drove to the studio she wondered, after she broke his discipline – and she was certain that she would - and he came on to her, if he would wear a condom. She had some in her dance bag, but decided she wouldn’t insist on or even offer him one. She never worried about STIs. Her only concern was that if he was a heavy hitter and took her bareback (she so loved the intimacy of skin-on-skin contact) would the custom crotch gusset be thick enough to absorb all his semen and her natural lubricant that drained out – even after she Kegeled his spunk into a baby wipe - or would it overflow and run down her thighs before she could get to the dressing room to wash up and change her soiled tights for the drive home or perhaps, if she was lucky, back to his place for the night?

Caressing the camel: She told me everything went just as she planned. He could hardly tear his eyes away from her body from her waist down. His gaze kept moving from her pointe-shoes to the orange cleft of her camel-toe. She was surprised at the end of break midway through the 90 minute class that she was still comfortable in her tights. She could tell he was weakening already as during a shoe change he had asked her out for coffee after class. But even more important from her prospective was than he had been far more hands-on while making corrections; adjusting an arm or foot, having her tuck her buns under her and finally tracing the back of his hand lightly across the twin wet mounds of her labia imprisoned under the tight microfiber of the crotch gusset. As she gasped and quivered at his touch she hoped the outer surface of the gusset was still dry.

The second time he gently stroked her camel-toe was after she changed into her GM pointes and was doing center work. He was having her do développés and he touched her there before he moved his hand to stroke her abs where the strength for a développé originates. The thrill that second caress caused was so intense her standing leg began to weaken. With a major effort on her part to focus she managed to retain her balance and the height of her working leg, but she was soaked with sweat from the effort. They ended the class by doing a bit of simple partnering waltz steps and finger turns and she ended up in his arms. With one hand behind his head to hold him close she deep kissed him while taking his other hand and pressing it into the bulging crotch of her tights. There was a scramble to unroll her tights, unfasten the belt and pull her tights down below her hips while she unbuckled his belt, unzipped his pants and gently pulled his erection out of his boxers.

An unintended consequence: Now, weeks later, she had come to us at the clinic because her period was a week late and she had tested positive for hCG indicating that she was newly pregnant. Since her ballet teacher had been her only sexual partner, other than soloing with a vibi and dildo, she knew who the father was, but hadn’t told him because she intended to terminate her pregnancy. A pregnancy is very rare with a ParaGard IUD inserted, but they do occur. She said she had loved being in his arms, having him thrust into her even when, since he is very large, he rammed her ripe cervix and especially when he gave her the most intense G-spot orgasm when he took her from behind and she went rubber legged nearly falling off pointe while balanced on the platforms of her Gaynors.

The vacuum aspiration took about 45 minutes involving giving her a sedative, having to dilate her very tight cervical os and extracting the reproductive tissue after the Gyn had removed the ParaGard which had been badly bent, possibly due to heavy cramping when her cervix was being rammed.. She was given a ten day course of antibiotics and we had her take 800 mg of Ibuprofen to minimize any cramping. She should be able to have her IUD replaced in two weeks and we are recommending a GyneFix with the strings removed. GyneFix, with its new implant procedure is far less likely to be deformed or expelled than ParaGard or Mirena during a woman’s periods or heavy cramping due to rough sex. She’s looking forward to her next private class with her teacher, but will use condoms until she gets her GyneFix implanted.
