Thank you for visiting.
Hikari is 25 years old and has heartbeat number 2.
From our conversation before the shoot, she was very polite and I knew she must be a wonderful person, but my first impression when we met was that she was not only a wonderful person, but as you can see from the sample images, she was even cuter than I had imagined. She has beautiful features and was constantly smiling during the shoot, and that smile was just too cute. She has a friendly personality and seems to like to talk, and at one point I got so engrossed in our conversation that I forgot we were shooting, and she was completely lovey-dovey with Hikari.
She was also very slim, 163 cm tall and weighing 45 kg, with small breasts and clearly visible ribs.
The pulsation of the abdominal aorta in this video is very easy to see, just like Asuka's, who we introduced previously, and when I gently touched it, I could even feel it twitching.
Perhaps it's because she's so slender and her heart is close to the chest wall. I recommend this model to those who like slender figures.
Hikari's heartbeat is available in addition to Heartbeat 2, and Heartbeat 1 is also available. A set of 1 & 2 is also available, and this set includes some very erotic heartbeats. If you're interested, please check out the sales page.
Also, starting with this shoot, we've increased the number of cameras, and depending on the video, we're shooting from different angles. It would be a waste to shoot a cute person like Hikari with just one camera.
In the future, I would like to continue to focus on not only sound but also video.
The contents are
Heartbeat when lying down
- Abdominal aortic pulsation and heart sounds
・Various blood pressures and heart sounds
- Heartbeat when you hold your breath
Heart sounds while smoking
- Heart rate when chest compressions are performed after exercise
- Heart sounds when breathing through a bag
It is as follows.
The video is 37 minutes and 6 seconds long.
First, I had him lie down so that I could listen to his heartbeat with a stethoscope.
Your heart rate is a little slow at 80 BPM. I'm sure your heart beats at about the same rate even when you're lying down at home. I'd love to put my ear directly to your chest and listen to your heartbeat every day.
From there, when I gesture to her to stretch, her heartbeat quickens a little, and some of Hikari's ribs become visible.
Because she is topless, her body is even easier to see, making her look like part of a human anatomy model's skeleton, and you can't help but imagine a heart beating deep within those ribs.
Finally, when you get off the bed and stand up, your heart rate will suddenly increase. It will reach nearly 13 BPM, just like the heartbeat of a mouse.
Just getting up used up a tremendous amount of power in Hikari's heart.
As mentioned at the beginning, the pulsation of the abdominal aorta and the sound of the heart are very easy to see, and if you bring the camera close to the navel, you can clearly hear it pulsating in time with the heartbeat.
I was surprised when I first saw it, but Hikari herself was the most surprised.
Even when photographed from a distance, the light reflects off the heart, making it easy to see how it moves and buckles, almost as if it were a heart. This is undoubtedly Hikari's weak spot, and perhaps it's fair to say that showing such an important part without hiding it is a flaw in the human body.
Blood pressure and heart rate were measured three times: while lying down, while sitting, and shortly after exercise.
When I first had my blood pressure measured while lying down, it was about the average for a woman in her twenties, which was healthy despite her being incredibly thin. If I had to say, I'd say my lower blood pressure was a little high.
When I asked Hikari to take a look at it, she laughed and said, "It's neither good nor bad."
When we measured her blood pressure again while she was sitting, her systolic blood pressure had dropped. "Why?" Hikari asked in surprise.
Finally, we measure your blood pressure after exercise.
This photo was taken after the subject exercised for other purposes, and their blood pressure was measured and only the results were displayed on camera.
As expected, my blood pressure is higher than before, since I just exercised. However, it's not high enough to be considered high blood pressure, so I guess it's just like someone in their 20s.
When you hold your breath while wearing a pulse oximeter, your heart rate will initially drop from 100 BPM to a normal rate of 100 BPM.
From there, the patient's heart rate began to increase, and the oxygen saturation level began to drop slightly.When the patient resumed breathing, the meter's numbers disappeared for a moment due to an error, but when they appeared again, the oxygen saturation level had dropped to 93.
We also asked them to hold their breath for longer periods of time during the second and third sessions.
Although her oxygen saturation level didn't change much, it was clear that the moment Hikari stopped breathing, her heart rate dropped and she exhibited a diving reflex.
Next, Hikari told us that she smokes regularly, so we listened to the sound of her heartbeat while she was smoking during her break.
Hikari asked, "Will it really make that much of a difference?" and had me listen to the sound of my own heart while I inhaled.
Compared to other videos where the subject was taking deep breaths, I noticed that the rhythm of the sound changed when they were inhaling and exhaling, but when they were smoking, the heartbeat rate remained constant throughout, maintaining a consistent rhythm. I wonder if this is because the sympathetic nervous system is stimulated by smoking.
When chest compressions are performed after exercise, the patient is asked to step up and down on a step stool, and chest compressions are performed with the heart beating rapidly.
Of course, we obtained permission from Hikari in advance to ensure this is legal.
Normally, it would be almost impossible to put your hands on a woman's chest in this condition and apply strong pressure.
For heart sound 1, I applied compressions in a normal state, and even then the heartbeat was very easy to hear, and this time it was just as easy to hear. I could feel the rapid heartbeat of about 165 BPM ("tottotottototto") directly in my hands, and I could also feel the lungs moving up and down with her heavy breathing. In the video, my hands move in sync with Hikari's chest movements.
I was so worried that if they applied pressure to his heart in that condition, it might burst.
After a while, my heartbeat began to calm down and the vibrations I felt in my hands became gentler than they were immediately after exercise.
To hear the heartbeat while breathing through the bag, the patient is asked to place a bag over their head, rest, and breathe slowly.
We asked Hikari to wear as large a bag as possible over her head, and she kept it on until it became too uncomfortable and she had to raise her hand, so the video is a little long.
At first, the oxygen saturation level was 99 and the heart rate was 71 BPM, which was quite normal.
If Hikari had continued breathing without the bag over her head, it would probably remain like this, but her head is now covered and sealed in a sealed bag. No matter how big the bag is, there is a limit to the amount of oxygen it can hold, and she is breathing in the same old air she exhales, so her normal breathing is gradually becoming more labored. Her oxygen saturation is also gradually decreasing, and when it reaches 78, she raises her hand. Her heart rate is also increasing in inverse proportion to the decrease in oxygen saturation, and is now over 100 BPM. We can also hear premature contractions, "dock, dock, dock, dock, dock, dock, dock."
Even though the body is exposed to the outside air, it cannot replenish oxygen from there, and Hikari can only get air into her lungs through her nose or mouth.
After removing the bag, we looked closely and saw that Hikari had exhaled air and had left many droplets on the bag, so we have also captured these in the photo.
