Divers in romance (part 7) The night after a diver passed away 潛水員的浪漫（七）潛水員過身後的一夜
Please notice that anyone who is prudish doesn't suitable to read this article.
All of us were upset to see such accident.
Camilla and I went back to our room to have a rest.
I heard she was crying and she said: "We just had talked during the breakfast, before her body soon became pale white when she was saved and brought on board." I saw that her eyes were swollen up with tears.
I was thinking whether I might console and alleviate her. We have stared into each eyes for a few minutes, then her hands put on my neck and her head rested on my shoulder. I then hugged her and said: "If you feel comfortable, I don't mind you are crying on my shoulder."
I felt both our heartbeats were increasing and our breath were getting heavily. Our lips were getting closer and closer, then we have been kissing.
Her tongue was going inside to my mouth, and so did I. I reached a point of no return that I couldn't control my emotion. I caressed her face, neck, and breasts, and so did her. She stroked my penis, and has been making some humming and droning sound for me and took off her clothes and bra. I stroked her breasts and felt her soft breasts and hard teats. Then my fingers went inside of her thigh. Her clitoral area became more swollen with arousal, and she got even more sensitive.
She then changed her position on my upper side and sat on me. Her long and untied hair rested on her body naturally, which was just long enough to cover her nipples.
She was keeping to kiss with me. We shared our breaths and sweats. I was so flustered. I shouldn't go further because I haven't prepared yet, but my libido has driven my emotion. I would not think that we might make love during the trip. Making a girl pregnancy is really hurt when she needs an abortion and I don't want to become a father too.
As Hong Kong's governing is getting worse, political neutral and fairness have gone. Also, the independent of jurisdiction is deteriorating and it has become a police state. In short, Hong Kong has become a tyranny. It is really hurt for a child in the future. Moreover, the population is too much in the world.
Then I said to her: "We should hold up, because I haven't prepared and have any condoms. You may have pregnancy." She replied:"Don't worry. It is ok."
While I was hesitating, she took off our smalls. She put my penis into her vagina, and we have soon become a unity. Her supple breasts were wobbling, while she moved harmonically. Having coitus was an exercise that required an enormous workload, which we shouldn't do after we had repetitive dives within 24 hours.
When I felt I was going to have ejection, I asked her: "Should I take it out?". I knew this was not a good idea for birth control, but it might have little help. She replied: "Keep inside and eject into my body."
I felt she was so ecstatic and thrilling. Her body was tense and spasm. She had an orgasm that was so good she laughed her ass off from the euphoria. Both of us got heavily sweaty, even though I have turned the air conditioner to work at full capacity. I asked her: "Do you need to have a shower?" She said: "She wants to keep my sweat and smell for a while." Then we hugged each other and kissed. After we have had sex, both of us underwent some kind of catharsis.
We giggled each other, suddenly, I was aware and said: "I don't want to be another example of decompression sickness (DCS) victim, we were indispensable to drink a lot of water now."
Why did I say that?
Recently, DAN, which is an organization
to promote dive safety and offers diving insurance, had a medical report that stated a case of DCS. There was a couple who went to a liveonboard diving journey and the female suffered DCS. After an investigation of their diving profile, DAN found that they abided by the rules of no decompression limit. Finally, they studied their activities that they had done after dives and learned that they had sex. This was the reason why the female suffered DCS. When I had taught diving class, I usually said that you don't do any strenuous exercises and hot bath after dives that are referred to playing basket ball or football. I have added this warning to my students after that.
We went to the pantry to have a large of glass of water. I told her we should keep monitoring any DCS' symptoms for an hour. After I had a lot of water, I went to bathroom to have urination. She suddenly barged in the bathroom to give me a back hug. She was so naughty.
She told me that she have had birth control since she had dating, because her mother has been caring about her and brought her to a doctor who advised her to use intrauterine device, IUD, which requires less maintenance and she won't have any chance to use it incorrectly like condoms. She uses ParaGard IUD, which doesn't have hormones and has protection for pregnancy up to 12 years. This IUD is a tiny device that's put into her uterus and it is one of the most effective birth control methods, which claims 100% protection.
After I have known this, I felt a great relief of worrying her to have baby.
Lucky, both of us didn't feel any DCS symptoms after an hour.
After our vessel has taken 36 hours travelling, we arrived to the pier. They transferred the corpse to police for them to have an autopsy. We all stood on the starboard and joined in tribute. Then we sung laments to mourn the passed away diver.
As our flight would be on the next day, we stayed one night in San Jose.
We have booked two rooms before, so we requested to arrange a twin rooms. I wondered why she always required a single room for her every trips. She answered me in embarrassing because she needs to have masturbation for having a good sleep. Jilling off to have a strong orgasm makes her a decent sleep. Then I asked her: "Do I need to let you alone tonight?". She replied: "Your stay may help me have a nice dream."

Divers in romance (part 6) an accident happened in Cocos Island潛水員的浪漫-Cocos 島的奪命意外（六）

The vessel sailed in the evening. We had a lot of time to prepare our diving gears, because we took 32 to 36 hours to there.
The other guests came from difference countries. It was lucky that there were no Chinese, as we are HongKonger.
They have two speed boats for travelling us to the dive sites, so we were separated into two groups, but one guest whose name is Rohina Bhandari was in a single group. She yelled Camilla when she arrived the pier. She said Camilla's mother is her company legal advisor for her company Hong Kong region business. She said she was a beginner scuba diver and she learned this dive site from Camilla's mother, because she told her that her daughter and I would travel to Cocos Island after she has known that she just got a beginner scuba licence. She had a soft spot for the hammerhead sharks because she likes them swimming elegantly.
She booked this trip one month before its departure, but the operator rejected her in the beginning because she failed to meet the requirement of sufficient dive logs and minimum level of license. After she had fought tooth and nail, the operator required her to hire her own dive master to dive with her for safety. She even brought a textbook of beginner scuba diving to read on board.
After we had seen her performance underwater, Camilla and I thought she was unsuitable to dive here. She was out of her depth in this dive sites and even this trip. The operator got their risk finally even though she hired her own dive master. Our worry came true on the third days of our trip.
We saw a tiger shark come to follow us, but it has kept a distance from us, because the bubbles that are exhaled by divers are very disturbing and annoying to it. I have known it was not too dangerous, because sharks rarely attacked scuba divers except they did hunting and feeding.
We had 3 dives and one night dive on the first day. It was amazing to see a lot of hammerhead sharks that was swimming toward us so close. The dive site of our scheduled first dive on the second day was Manuelita Coral Garden. When our dive was going to the end, Rohina Bhandari was doing safety stop at 5 meters.

Divers in romance (part 5) Visit Camilla's family潛水員的浪漫（五）首次造訪
Since we accumulated sufficient logs, we have been scuba diving instructor.
She has really touched my heart, since we were in the Australia's trip. We have met more frequently even in non diving activities and have also had more personal conversation.
Sometimes, I thought whether it was the right moment to say those three little words to her, but I made jokes on her to cover my silly feeling. She has never burnt my bridges even though I made her embarrassing. She has always forgiven me when I gave her a hug, or pecked her front head softly.
One day, she told me that her mother's birthday was on the coming Saturday and she has prepared a celebration at her home. She asked me whether I could come to her mother's birthday party.
As I was the first time to meet her mother, I worried to prepare a suitable present for this visit, but Camilla said I need not shop around it. I dressed up with my only suit on that day. She came to pick me up and passed me a box of ear rings
and a bunch of lily.
They were the presents that she wanted me to butter up her mother.
It was the first time I visited her home, which is at Black's link where is near the Peak, Hong Kong Island. Her house is a three stories building with its own swimming pool.
When we entered into her house, her mother was sitting on a couch and reading a magazine.
I gave her a greeting for her birthday and she came to give me a big hug and let me sit next to her. After I had given her the lily, she was enchanted. That Camilla knows what her mother likes made me have a good reputation for her mother. Although she was very impressed, I knew she has known this were arranged by her daughter.
Her mother is a solicitor and works in an international law firm as a partner. She usually talks in English with Camilla. I have known why Camilla's English ability is so excellent. I had difficulty to speak fluently, so they encouraged me to speak more and taught me what my mistakes were and how I was able to correct them. It is very useful and this is the reason why I can write blog in English now.
Her mother and I talked various topics from economy to human rights. I read between lines from her point of views. I known that she is a liberal and feminist. Camilla said her mother let her have highly freedom to do what she likes. If Camilla wants, she might ask her mother opinions, but she makes her decision finally. I thought it was quite rare that a parent has given their children to have such high degree of freedom.
Her mother said she had had some worries when Camilla said she would learn diving, until she has known her daughter had a trustable classmate who has been her buddy. I have been aware that Camilla shared everything with her mother. This is the main reason why her mother let her daughter do what she wants.
When the time has closed to the dinner, her father came. He just finished a business trip and his flight was delayed, so he couldn't come early.
Her father asked me where would be my next expectation. I told him Camilla and I just watched a documentary of Cocos Island. There are many scalloped hammerhead sharks that swim shallowly. The island is located about 550km off of the coast of Costa Rica, to where we need to take 32 to 36 hours. Her father worried how Camilla could take such long trip on board. Camilla proudly said she has learnt how she has been able to tackle seasickness. Her father praised her that she has had a good boy friend to train her. I saw she was blushing.
Her mother led her servants to cook a slap-up meal for us. During the dinner, her father asked me a lot of my career. He is a usual businessman, so we also talked and shared some point of views about government policies. From my observation, Camilla and her mother like friends rather than the relationship of mother and daughter.
Camilla did some researches for our Cocos Island trip. There are only two companies, which run liveonboard trip to Cocos Island for tourists and divers. One of the companies, which is Undersea Hunter, offers a submarine expectation for guests.
They bring guests down to 300 meters depth, where is hard to go by scuba diving because it requires technical diving technique that takes dead great risks.
Undersea Hunter has two vessels named Argo and Sea hunter. Argo is larger because it hosts the submarine.
Someone might know Costa Rica from watching the World Cup. This country is in the middle of America and is located at the north of Panama. She is one of the countries that doesn't equip any armies and cares about environmental protection. She has over 30% area covered by tropical rainforest, and has declared Cocos Island and its surrounding ocean as a national park since 1978, so fishing has been prohibited. This is the reason why she has only licensed two companies to operate there.
She has really touched my heart, since we were in the Australia's trip. We have met more frequently even in non diving activities and have also had more personal conversation.

Divers in romance (part 4) My first oversea diving trip - The Great Barrier Reef, Australia 潛水員的浪漫（四）大堡礁之旅
The most difficult thing of the instructor's course was to overcome the challenge of low water temperature, because our course took place in the winter. The water temperature was as low as 15 degrees Celsius.
The second difficulty was rescue examination. I was almost exhausted during the examination that required us to pick a victim who drowned under 6 meters depth from the bottom
and brought him onto the beach. Following, I gave CPR on him.
Other than a series of examinations, the remaining requirement was to fulfil the accumulated number of dives. Therefore, we planned an oversea trip.
There are so many dive sites we want to visit. Camilla suggested Great Barrier Reef, Australia. Then I asked her whether she can stay on a vessel for 9 days and resist seasickness. She said she has had no seasickness during the past local trips, as the sea was not too rough. I said I am highly resistance to seasickness, because I had an experience recently.
My mother was passed away last years. Her will was scattering her cremains at sea. My family got on a ferry that was provided by the Food and Environmental Hygiene Department of Hong Kong government. This service is free of charge because they provide an incentive to persuade more people to take this option for their relative's cremains, such that it will decrease the demand of riches.
The leaflet on scattering of cremains at sea.
As this service was not too popular at that time, they just hired a small ferry. When they parked at the scattering area where was at the east of Tung Lung Chau, the ferry didn't have anchor.
It has been being swung for the whole ceremony.
I saw almost all the guests who began to vomit shortly except me and my family. I then make a not too scientific conclusion. That anyone has the ability of resistance to seasickness is by genetic. I have to thank my parents.
I told her my experience and asked whether she might adapt a live on board journey.
She replied she would be alright and asked: "If I got seasickness, would you take care of me?"
I was stunned for a moment and said "Uh-huh".
Camilla turned her head and looked at me.
I said again with smile: "Certainly, of course."
She did some research about live on board information and chose a route to Flinders Reef, Coral Sea, which was operated by Mike Ball dive Expeditions.
Their vessel has twin hulls. She thought it may be more stable, but she was wrong.
The vessel, Spoilsport, departed from the town, Townsville. After we had traveled several hours, the vessel became to ride on heavy swells. It was rocked back and forth even though it has twin hulls.
She felt dizzy and coming to vomit. I told her she might go outside to have fresh air and look distant objects. Outside her room, there is a dive deck. We sat on the bench. After we had sat for a while, I felt her shiver. I asked her whether she felt cold. Then she sat between my thigh and made me to cuddle her. My left hand surrounded her belly and right hand put on her shoulder and chest. She caressed my hand and said she was warm. Smelling her hair and touching her skin, I couldn't resist my basic instinct. As she was embraced closely, she had to feel it.
After she had sat for a while, she felt better. When she had fallen asleep, I carried her in my arms like a bride back to her room.
She looked ravishing while she was sleeping. I was stunning for a while then I kissed her forehead and put a blanket on her.
Have I been fond of her or fallen in love with her? I struggled to stay or leave for several minutes.
We arrived in Flinders Reef at night. Before each dive, the programme manager, Black, introduced a very comprehensive briefing for the dive site. As Australia diving practice, no dive master leads divers. They require divers in buddy system to dive by themselves.
The visibility of Coral Sea was very great. The operator, Mike Ball, guaranteed 45m visibility. For environmental protection, they set some permanent anchors on each dive sites. We made our entry from the stern, which is over 2m above the surface. You may watch the below video. The guy who plays with the sharks stands at this entry platform. From this video, you will know their highlight is scuba zoo where has two large cages for divers to watch sharks' action safely. They fished some big tuna fishes during the voyage, chopped them into several pieces and put them into a basket.
The programme director, Black, who was drop dead gorgeous in wearing his marine camouflaged long sleeve wet suit with hood and a pair of long blade fins, shook the basket to attract more sharks to gather there for us taking photos.
Unfortunately, this is a risky job. He was bitten by a shark and made a teeth mark on his right upper arm during his next schedule of our trip.

Divers in romance (part 3) We have been the Scuba diving instructor潛水員的浪漫（三）成為水肺潛水教練
We joined a master diver course, which consists lectures only.
This course teaches the diving related knowledge much comprehensive. The course has twelve topics, which are the enhanced version of beginner course.
We learnt how the figures of the dive table were calculated.
The current common dive tables that show on the left hand side are based on Haldane Theory, which was developed and researched by a British physiologist John Scott Haldane in early 20th century.
After a series of experiments, he found that decompression sickness is governed by inert gases, which are mainly nitrogen, that has been absorbed by body's tissues under pressure. To make use this theory for diving, US's Navy simplified it into a table that divers can easily use it for dive planning. Other diving institutes referenced Navy's table to make their own dive tables later.
This table is based on two main factors.
1. The amount of saturation of nitrogen under a given depth and temperature in difference tissues has been
absorbed.
2. The time of nitrogen releases half of its original amount when pressure has been reduced.
Nowadays, the diving society has developed a more advanced model that
is Reduced Gradient Bubble Model (RGBM), which has been developed from the research leading by Dr. Bruce Wienke
at Los Alamos National Laboratory. This model is based on gas dynamic, which will be too difficult to be explained in this story, because one of the application of this theory is on the soundless travelling of submarine.
These series of courses had so many lectures and required dive logs that we needed to keep to fulfil the course requirement. It was a good chance for me to have excuse to meet her. We have usually met to have lunch or dinner before taking lessons and she has always drove me to my home after lessons or diving. I appreciated her to do me a favour, but I was quite worry about her driving alone to return home.
Diving in Hong Kong had a lot of interesting things that could be seen. Once, Camilla saw a flounder that was trapped by a abandoned fishing net. We saved it finally and it was swimming happily to return to the ocean.
Maximizing your effort, you must keep your leg straight, instead of kicking like riding a bicycle. I saw an instructor whose finning was as bad as the below video.
After master diver course, we had started to study instructor course. Why did we jump to instructor course? It was because the course director combined rescue diver, dive master and instructor course into a combined course. That we just had a single examination of rescue and first aid and CPR was a great advantage for us.
As diving experience that logged by number of dives is a basic requirement of difference courses, we have kept to have fun dives in Hong Kong. In the summer, Sai Kung has many visitors who cause over demanding of car parks. One time, she took over half an hour to look for a car park, and we almost missed the schedule of the boat. Then she said: "I need to ask for my father to borrow his car." I thought why difference cars may have difference priority for parking.
In the next week, she came to me with a new car that was a Benz and she sat at the back. I wondered whether the driver is her father. She then introduced him to me that the man whose name is Simon was her father's driver. I then understood the meaning of borrowing her father's car. I also felt relief that she needed not drive alone to return home.

The current common dive tables that show on the left hand side are based on Haldane Theory, which was developed and researched by a British physiologist John Scott Haldane in early 20th century.
After a series of experiments, he found that decompression sickness is governed by inert gases, which are mainly nitrogen, that has been absorbed by body's tissues under pressure. To make use this theory for diving, US's Navy simplified it into a table that divers can easily use it for dive planning. Other diving institutes referenced Navy's table to make their own dive tables later.
This table is based on two main factors.
1. The amount of saturation of nitrogen under a given depth and temperature in difference tissues has been

2. The time of nitrogen releases half of its original amount when pressure has been reduced.
Nowadays, the diving society has developed a more advanced model that

These series of courses had so many lectures and required dive logs that we needed to keep to fulfil the course requirement. It was a good chance for me to have excuse to meet her. We have usually met to have lunch or dinner before taking lessons and she has always drove me to my home after lessons or diving. I appreciated her to do me a favour, but I was quite worry about her driving alone to return home.
Diving in Hong Kong had a lot of interesting things that could be seen. Once, Camilla saw a flounder that was trapped by a abandoned fishing net. We saved it finally and it was swimming happily to return to the ocean.
Diving in Hong Kong is also a good chance to practice finning and control buoyancy. The most common finning technique is flutter kick that provides the most powerful propellant.
I didn't know how he could be certified as an instructor. He made a tragedy after he had been an instructor for one year. His buddy was dead during a dive, but someone told me that he was teaching an advanced scuba diving course.
After master diver course, we had started to study instructor course. Why did we jump to instructor course? It was because the course director combined rescue diver, dive master and instructor course into a combined course. That we just had a single examination of rescue and first aid and CPR was a great advantage for us.

As diving experience that logged by number of dives is a basic requirement of difference courses, we have kept to have fun dives in Hong Kong. In the summer, Sai Kung has many visitors who cause over demanding of car parks. One time, she took over half an hour to look for a car park, and we almost missed the schedule of the boat. Then she said: "I need to ask for my father to borrow his car." I thought why difference cars may have difference priority for parking.
In the next week, she came to me with a new car that was a Benz and she sat at the back. I wondered whether the driver is her father. She then introduced him to me that the man whose name is Simon was her father's driver. I then understood the meaning of borrowing her father's car. I also felt relief that she needed not drive alone to return home.
