This is a set of heart sounds 1 and 2 from Sae, age 31.
Please be careful not to make a mistake when purchasing.
Additionally, this video exclusively includes a recording of "Sae's heartbeat while she was masturbating in full nudity."
She had fair, smooth skin and perfectly formed features, making her look like a doll; she was incredibly beautiful.
I never thought someone this cute would agree to be photographed, but I mustered up the courage to ask, and she readily agreed, which made me incredibly happy.
On the day of the shoot, she arrived earlier than scheduled, and when I met her in person, she was even cuter than I had seen in the photos beforehand. For a moment, time seemed to stop.
Sae-san was very quiet at first, but as the shoot progressed, she opened up and it turned out to be a very enjoyable shoot.
Furthermore, Sae has a constitution that makes her prone to arrhythmias when her heart rate changes, especially when it speeds up, such as when she exercises or changes her posture. She was experiencing frequent premature contractions, similar to Reina and Miina, whom we introduced previously, with a "thump, thump, thump, thump, thump" sound.
From what I've heard, there are easily more than 10 instances of premature contractions in this video alone, and the electrocardiogram also confirmed their presence in the waveform.
It seems that she had never been diagnosed at a hospital, so it appears she has the same condition as Reina, a hidden arrhythmia. We've really found an incredible talent!

Also, the length of the "heartbeat sound while masturbating in full nudity" exclusive to this video is 8 minutes and 48 seconds.
First, they introduced themselves, and then they used a stethoscope to listen to my heart sounds.
Sae, who says she's a little nervous, has a heartbeat that goes "thump, thump, thump, thump," and it's not just a little nervous, her heart rate is quite fast at around 106 BPM.
Wouldn't you say that Sae's current state is exactly like saying her heart is about to jump out of her chest from nervousness?
When I asked her if she would let her boyfriend listen to her heartbeat if he had a heart fetish, she said, "I think I'd be embarrassed..." It seems that even her boyfriend finds it embarrassing to listen, and since I, whom she had just met, was listening to it the whole time during the photoshoot, her heart was beating faster because of the embarrassment.
During the shoot, we asked her to place her hand on her chest to see if she could feel her heartbeat, and she also answered questions such as, "Why did you decide to participate in this photoshoot?"
Sae's heart was beating so fast from embarrassment and nervousness that it felt like it might jump out of her chest. When she listened to her own heartbeat, she said, a little shyly, "It's faster than I thought!"
That means it's that fast.
The embarrassed look on her face at that moment was incredibly cute. Her good looks make it even more so.
We had them place a stethoscope on various parts of their body and listen to the differences in how the heartbeat sounded.
Around the apex of the heart, you can hear a low-pitched sound, and around the pulmonary artery, you can hear the heartbeat as if it's far away.
Either way, her heart was beating fast, and Sae-san couldn't help but chuckle at how fast it was, saying, "It's fast no matter where you listen!"
Normally, drinking water makes your heart beat faster, but in Sae's case, it doesn't seem to change much. That said, it's already fast, so it would be a problem if it got any faster.
Finally, I was asked to take a deep breath to calm my heartbeat, but it doesn't seem to have made much of a difference here either.
Sae-san also mentioned that her exhalation was slightly slower than her inhalation, and indeed, it did seem a little slower. However, as soon as she inhaled again, her heart rate would quickly pick up again, consistently exceeding 100 BPM. Perhaps Sae-san has a naturally fast heart rate. (This is just my personal opinion.)
When chest compressions were performed, the heart sounds indicated that not only the heart but also the lungs were being compressed. When the compressions were released, the patient took a deep breath, and their chest expanded accordingly.
If you zoom in on her chest and press down, you can see that my hand has sunk about 5 centimeters into Sae's chest, and I think you can see from the video that I'm not acting, but pressing with all my might.
I always push the limits during these photoshoots, so the models' reactions vary.
Her hands were moving slightly in time with her heartbeat, and seeing the adorable and beautiful Sae's heartbeat was so realistic that I got so excited I almost got a nosebleed.
When I did squats, I could clearly hear premature contractions in my heartbeat.
Sae, who doesn't usually exercise, starts doing squats, and her already fast heartbeat quickens even further. Several times during the squats, you can hear her pulse skipping for a moment, making a "thump, thump, thump, thump, thump, thump" sound.
When I stood up after the squats were finished, I noticed that my heart was beating fast, and I had more than 10 premature contractions occurring at a rate of about once every four beats, making my pulse irregular.
When she took a deep breath, the premature contractions stopped, but I was surprised that they occurred so much after just a little exercise. When I told Sae about it after the shoot, she was surprised herself, as she hadn't realized they were happening.
Next, we had the patient perform step-up exercises, during which we measured their electrocardiogram and recorded their heart sounds using an electrocardiograph.
This exercise is more intense than squats, and Sae-san said during the workout, "This is much harder!"
The video is occasionally blurry, and the electrocardiogram waveform is distorted during the step-up exercises due to movement, but the measurements are clear after the exercises are finished.
During the step-up exercise, the heart rate gradually increased, reaching 145 BPM. Immediately after finishing, premature contractions occurred, sounding like stumbling, with a "thump-thump-thump-thump, thump-thump-thump" rhythm. The electrocardiogram also briefly cut out as the heartbeat, as heard through the stethoscope, and the heart rate rose even further to 151 BPM. It appears the heart has overheated.
When I did the squats earlier, all I heard was sound, but when I looked at the electrocardiogram, I could see skipped beats, and the waveform clearly showed that they were premature contractions.
Also, she was breathing much more heavily than when she did squats, and when I asked her if she could feel her heartbeat by placing her hand on her chest, she kept her hand on her chest for a while and then said breathlessly, "I can tell it's really fast," and I also placed my hand on her chest, and I could feel it beating really fast just by touching it.
After taking deep breaths, the premature contractions subsided and Sae's heart returned to normal, but her heart rate was not decreasing quickly enough, so we asked her to sit up on the bed. (We switched to the video feed from another camera when she sat up on the bed.)
Sitting down helped the patient calm down somewhat, but their heart rate remained well above 100 BPM, and they also experienced one premature contraction.
For the electrocardiogram and heart sounds recorded while exercising with a bag over the head, the patient lies on a bed with a bag over their head, sealing it tightly, and performs leg raises.
The heart rate, which was initially 90 BPM, gradually increased, and several premature contractions occurred along the way, with a "thump, thump, thump, thump, thump" sound. The electrocardiogram also confirmed that the pulse was skipped.
Her heart rate was over 100 BPM at that time, so it's possible that Sae's heart is prone to this when her heart rate exceeds 100 BPM due to exercise or other physical activity. We can discover a lot of things by looking at an electrocardiogram.
Midway through, she raised her hands due to lack of oxygen and loosened the bag, at which point her oxygen saturation level dropped to 85. After a short while, the bag was resealed and she continued exercising. Finally, she reached her limit, so the bag was removed and she was allowed to rest. Gradually, her heart rate calmed down and her oxygen saturation level returned to normal, showing that Sae also consumes oxygen to survive.
The carotid artery pulsates with each heartbeat, and its movement is easily noticeable even from a distance. If I saw it moving like that on a train, I would definitely stare at it.
When I touched it with my finger, I could feel it beating, and I couldn't help but imagine what would happen if I pressed down hard on it.
With echocardiography, when a probe is placed on the heart, the heart, beating at approximately 90 BPM, is displayed on the echocardiogram screen.
The shape is round and the size is about the same as Sae's fist, so I think what's being projected is almost life-sized Sae's heart.
We also showed Sae her own heart, and when we asked her what shape it was, she said, "Is it round?" and also, "It's alive!" It seems that seeing her heart beating made her truly realize that she was alive. After the shoot, when we asked her what other shapes it looked like besides round, she said it looked like a fish. She said the same thing in the sample video.
I asked them to hold their breath, but their heart rate didn't seem to change much, just like when they take a deep breath.
Next, we performed an echocardiogram to examine the heart immediately after the step-up exercise.
During exercise, the patient experienced several premature contractions and skipped beats. After the exercise, we had the patient lie down on a bed and placed a probe on their chest containing their rapidly beating heart. The ultrasound image clearly showed that the heart was beating faster than normal.
You can tell from your heart rate that you've been getting plenty of exercise.
Sae also noticed the difference in movement compared to normal, saying, "That's fast!" and chuckled a little at how fast it was.
After taking a deep breath to calm my heartbeat, at around 45 minutes and 20 seconds, I heard a "thump, thump, thump, thump, thump, thump" sound indicating premature contractions, and on the ultrasound, it appeared that my heart was behaving somewhat abnormally.
We have a separate video showing only the ultrasound screen, so please feel free to take a look if you'd like.
For the heart sounds during masturbation, we had participants wear an electrocardiogram while masturbating and observed the changes in their heart rate during that time.
Before she masturbated, I asked her questions that would probably be considered sexual harassment if asked in everyday life, such as "How many times a week do you do it?" and she answered them.
Then, as you apply the electric massager, adjusting its intensity, to masturbate, your heart rate will increase in response.
Occasionally, she lets out a sigh-like "Mm..." and her pleasure intensifies, her heart rate continues to rise, and finally she lifts her hips and reaches orgasm. You can tell that her heart rate is at its highest at that moment, indicating that she's truly climaxing.
Moreover, it seems that one time wasn't enough for Sae, as she immediately started masturbating a second time. It turns out she actually enjoys naughty things, which is quite a charming contrast. It took her longer to reach orgasm this time than the first time, but her heart rate gradually increased in the same way, and in the end she came again, lifting her hips, and she looked incredibly pleased.
Although there were no premature contractions, seeing such a beautiful and cute woman doing such lewd things, and watching her heart rate, pulse, the way she climaxed, and her heavy breathing, was incredibly exciting, and I found myself rewatching it many times while editing.
[This is the content of Heartbeat 2.]
To hear your heartbeat while standing and while squatting, we first ask you to listen to your own heartbeat using a stethoscope while standing.
Sae's heart rate is fast even when she's sitting, but when she's standing, her heart rate is 110 BPM, which is slightly faster than when she's sitting.
When you squat down, your heart rate slows down dramatically, and then when you stand up again, it speeds up again. At this point, you hear a "thump, thump, thump, thump, thump, thump" sound indicating that premature contractions are occurring.
When you squat down again and then stand up, the same thing happens again, so it's not a coincidence; it seems your heart can't keep up with the sudden change in your heart rate.
Additionally, we took electrocardiograms while the patient was standing and squatting, so we have included those images as well.
When the patient was asked to squat down from a standing position and then stand up again, their heart rate rose to 125 BPM, and premature contractions occurred again. The electrocardiogram also showed a distorted waveform, and the intervals between the beeps were slightly irregular.
When you lie down, your heartbeat sounds calmer than before, and it's a reassuringly gentle pace. I feel like I want to put my ear directly to your chest and listen to your heartbeat.
When you stretch, your heart rate quickens slightly, and you can see from the change in your heart rate that your body is adjusting the amount of blood it pumps depending on your posture. Sae, who was listening, also said, "It's gotten a little faster!"
Finally, I asked them to stand up and I also asked them to listen to the changes in their heartbeat at that time.
For the recording of the heartbeat while she struck sexy poses, we asked her to take on a variety of poses, including poses that emphasized her chest and bold poses with her legs spread wide.
The camera gets really close, which makes it exciting to watch.
There were moments when my heart rate seemed to quicken slightly as I changed poses.
The electrocardiogram and heart sounds were taken while the patient was lying down and at rest, and the heart rate was monitored. Sae's heart rate is naturally on the higher side, and it is indeed higher than the average for women in their 20s.
When Sae-san compared her own heart rate to the average heart rate, she said, "That's fast!" and chuckled a little, and at that moment her heart rate increased slightly again.
If you take a deep breath, you might not notice much difference in your heartbeat, but if you look at the heart rate on an electrocardiogram, you'll see that the speed changes between inhaling and exhaling. Visualizing these differences numerically makes them much clearer than just listening to your heartbeat.
Finally, I asked them to hold their breath. They managed to hold it for a full minute, but they did take a few breaths midway through. That's proof that they pushed themselves to their limits.
At first, her heart rate decreased, but after a while, perhaps because she was feeling uncomfortable, her heart rate increased, and Sae's heart showed the normal response to holding her breath.
The electrocardiogram and heart sounds recorded during bag breathing were captured from the moment the bag was placed over the head and sealed, until the bag was removed and the heartbeat calmed down.
Initially, Sae's heart rate was a little fast at 94 BPM, but this is normal for her, and her oxygen saturation was 100, meaning her body had maximum oxygen. When she breathed inside the bag, her heart rate fluctuated between 97 and 102 BPM, and she also experienced several premature contractions.
Her breathing gradually deepened, and towards the end, no matter how much she inhaled, it seemed like she wasn't getting enough oxygen. Although her oxygen saturation level didn't drop much, remaining at 94, it seemed like it was already quite difficult for Sae.
When the bag was removed, the heart rate increased slightly, and premature contractions occurred. After a while, the heart rate gradually calmed down, and the oxygen saturation returned to normal at 100.
The electrocardiogram and heart sounds during the squat exercise showed that my heart rate was already on the higher side at 121 BPM even before starting.
When I started doing squats, my heart rate inexplicably decreased, but then it started to rise again, and then I began experiencing premature contractions. I counted at least five of them, and they were happening one after another, so my pulse was completely erratic.
When looking at the waveform, it appears that there are two patterns of waveform changes when premature contractions occur: one is a pattern where the interval becomes narrower and two waveforms appear in succession, and the other is a pattern where one beat of the waveform simply skips.
Based on the heart sounds, both appear to be premature contractions, but the waveforms look different.
After a while, my irregular pulse subsided, and although my heart rate was a little high right after finishing the squats, I took a deep breath at the end to calm myself down.
Regarding the pulsation of the solar plexus and the sound of the heart, while preparing for other shoots, Sae-san was looking at her solar plexus, and upon closer inspection, it was twitching and rippling, so we took a photo.
In the video, her body twitches in time with her heartbeat, and upon closer inspection, her skin is incredibly beautiful, with every single hair clearly visible.
I took a look at the pulsation in the groin area and the sound of the heart after I had already taken a picture of the pulsation in the solar plexus, and I noticed that it was twitching there as well, so I took a picture of that too.
The area where it's pulsating is in a very sensitive spot, and at first I thought about taking off my swimsuit to take the photo. However, I figured that if I did that, people's eyes would be drawn to something other than the pulsation, so I resisted the urge and took the photo with my swimsuit on.
Next, they measured my blood pressure.
Sae-san said her blood pressure was about average, so we had her lie down and measured it. It was about the average blood pressure for a woman in her 20s, which is very healthy.
When Sae-san tried on the results, she seemed a little pleased and said, "I think it's about average!"
Next, when I measured my blood pressure while sitting, it was extremely high, in stark contrast to the healthy reading from before. The text is difficult to read, but it says "High Blood Pressure," so it appears I have hypertension.
Sae-san also chuckled, saying, "It's more expensive than before..."
It's unusual for blood pressure to change so drastically just from a change in posture, let alone become hypertensive. Could this be related to a higher incidence of premature ventricular contractions?
In the chest compression test after exercise, participants were asked to perform step-ups and then immediately stand against a wall for chest compressions. Not only did their heart rate increase during exercise, but they also experienced numerous premature contractions, which was already satisfactory. However, when further chest compressions were performed, the vigorous beating of the heart was transmitted to the palm of the hand, and countless premature contractions occurred in rapid succession at a rate of approximately once every four beats. When these contractions occurred, it was noticeable that the heart briefly stopped beating.
My heart feels like it's about to break, but it was an amazing experience to have my heart, which was pounding so hard and experiencing arrhythmias, compressed like that.
When I held the camera with my other hand and pressed down, I could feel Sae's heartbeat through my palm, and that feeling was transmitted to the camera through my body, causing the screen to shake in time with her heartbeat. I think that conveys just how intensely her heart was beating, don't you?
Also, immediately after this photoshoot, they took my blood pressure in a separate photo shoot.
The results were surprising and, although difficult to read, they also showed a "high blood pressure" indication.
Regarding the sound of her heartbeat when her breasts were massaged, I was allowed to massage Sae's breasts and listen to her heartbeat.
Why are women's breasts so soft and feel so good?
And deep within those soft breasts is her heart, too. If I could hear her heartbeat while caressing her breasts, I think I could die happy.
When Sae's breasts were massaged, she seemed to be feeling something, letting out a small sound, and her heart rate was around 90 BPM.
The heartbeat during masturbation while fully nude indicates that the person is truly wearing nothing while masturbating.
Of course, she's also taken off her swimsuit bottoms, so you can see Sae's private parts, which aren't visible in other videos. The slight pubic hair adds to the eroticism.
(We have blurred out areas where required by law.)
She used an insertable adult toy during masturbation, and after the filming was over, she said it felt really good.
She reached orgasm twice here as well. The second time she reached orgasm, she lifted her hips and shook them violently, her breathing became extremely fast, and of course her heart was pounding. When we brought the camera closer to her carotid artery, it was twitching violently, and as her heartbeat calmed down, she also experienced premature contractions.
I'm so grateful that the visually appealing Sae-san did something like this for us.
