This is a set containing heart sounds 1 and 2 from Luna, who is 27 years old.
Please be careful not to make a mistake when purchasing.
Furthermore, we offer a slightly lower price compared to purchasing the items separately.
Luna has long, straight hair, a cute face, a calm demeanor, and a pure, black-haired look that almost all men would find appealing. She even dreamed of becoming a voice actress in the past, and her voice is incredibly cute. As you can hear in the sample video, she has what is commonly known as an anime voice.
Luna's heartbeat was at an average speed, but when she exercised, it was noticeably faster than usual, and I was soothed by the sound of her heartbeat and her cute voice.

After introducing myself, I was given a stethoscope and allowed to listen to my heartbeat.
There is no noise in the sound itself, and no arrhythmias are observed, so Luna is in good health. However, her heart rate is a little fast at 85 BPM, indicating that she is indeed very nervous.
Judging from her expression, her face is a little tense and stiff, and there's a certain nourishment to be found in the heartbeat of a woman like Luna who is feeling nervous.
She mentioned midway through that she was embarrassed to have her heartbeat heard, which might explain her faster heart rate. Moreover, it seems that having her heartbeat heard is more embarrassing for Luna than being seen naked, and it appears that she is currently in a very embarrassing situation.
I completely understand how Luna feels.
We also asked her other questions, such as why she decided to do this photoshoot and whether she would let her boyfriend listen to her heartbeat if he had a fetish for heart sounds.
Next, you were asked to listen to the sound of your own heartbeat.
Still a bit nervous, her heart was beating a little fast, and Luna, hearing her own heartbeat for the first time, said, "It's faster than I thought!"
I asked the patient to change the position of the stethoscope, placing it a little higher and listening. Then, when I placed it near the aortic valve on the opposite side, she said, "I can't hear much!" and what she heard was more like blood flow sounds than heart sounds. However, when I placed it near the lower part of her chest, right at the tip of the apex of her heart, she could hear the heart sounds clearly with a deep bass tone, and said, "I can hear it quite well here!" Even so, she said that the left side of her chest sounded the most like the heart, and she seemed interested in the differences in how her own heart sounds were perceived.
When the stethoscope was also placed on the carotid artery, a faint sound of blood flow could be heard there as well, conveying the sensation of blood being pumped to the head against gravity.
When Luna drank water, there was little change in her heart rate, and she herself said, "It's not changing much!" Most models show some kind of change, so it's rare to see no change at all like Luna's.
Finally, when we asked them to take a deep breath, we noticed a difference.
When you inhale, your heart rate increases rapidly, almost like a jump, but if you hold your breath briefly and then exhale, it slows down accordingly. As you near the end of your exhale, your heart rate gradually increases again, perhaps because you're feeling uncomfortable, and then increases again when you inhale again, creating a loop. Unlike when you drink water, the change in heart rate is very clear here, indicating a normal sinus arrhythmia.
For the exercise-related filming, we started by having the subject do squats.
Initially, the stethoscope was held between her swimsuit and her chest, resulting in a faint sound. However, she later held the stethoscope in place with her hand, and the sound became much louder.
Furthermore, during the squats, her heart rate gradually increased, and after just one minute from the start, it was pounding. "It's getting really fast!" Luna said, and by the end, her heart rate was 110 BPM, higher than when she was nervous at the beginning.
After it was over, I asked them to stand up and take a deep breath.
While inhaling, the heart rate doesn't change, but when you exhale slowly, your heart rate suddenly slows down and calms down. However, when you inhale again, it briefly returns to the speed of immediately after squatting, indicating a clear sinus arrhythmia.
Finally, we had the patient sit on the bed to allow their heartbeat to calm down.
Next, we had them listen to their heartbeats while they performed a side-to-side jumping exercise.
We also tried listening to his heartbeat with a stethoscope while he was jumping sideways, but we couldn't hear it because of the vigorous movement. That just goes to show how intense his movements were.
Normally, in everyday life, you wouldn't get a woman to do such strenuous exercise for you, let alone hear her heartbeat at that time, so the fact that she does it for you is just amazing.
During the exercise, Luna's breathing was incredibly heavy, and immediately after she finished, her heart was beating so fast, "thump-thump-thump-thump-thump," that I was worried whether her heart was even contracting properly. Her heart rate was probably over 160 BPM. If I could see Luna's heart with X-ray vision, I'm sure it would be convulsing. It was beating so fast, and while the step-ups that the other models always do are great, the side-to-side jumps are just as intense, and I can hear her heart beating at its absolute limit, which is fantastic.
When Luna heard her own heartbeat, she was so out of breath that she could barely speak, saying, "It's really, really fast, ha ha ha," indicating that she had truly reached her limit.
When I placed my hand over the stethoscope, I could feel a strong thud! thud! thud pushing back, so much so that I thought the heart might jump out of the chest at any moment.
After taking some deep breaths, I had the patient sit on the bed, and then lie down again. The rapid heartbeat gradually calmed down, and although I was worried it might stay that fast, it returned to normal, which was a relief.
When I compressed Luna's chest, I could clearly hear her heartbeat despite her large breasts, and my body was shaking in time with her heartbeat. My body, which weighs hundreds of times more than her heart, was shaking so much that it wouldn't be surprising if it burst. That's how much strain was being placed on her heart.
The rate of compression doesn't change much, but each heartbeat becomes stronger, as if resisting being crushed.
When I zoomed the camera in on her chest and applied pressure again, my hand twitched in time with her heartbeat, and Luna's body also swayed slightly in time with her heartbeat. You can see the movement of her heart throughout the entire video.
When using an electrocardiograph, a clear waveform is displayed on the screen once electrodes are attached.
The electronic beeps from the electrocardiograph and the sound of the heart can be heard at the same time, indicating that the electrocardiograph is accurately capturing the heart's movement.
Her heart rate seems a little high for someone in their twenties, and when I showed Luna the average heart rate for women in their twenties and compared it to hers, she also said it was a bit high. I wonder if she's still feeling nervous.
When I ask them to take a deep breath, and they take a big inhale and exhale slowly, their heart rate drops sharply by about 20 beats per minute, and then as soon as they start inhaling again after exhaling, it rises just as quickly back up to its original heart rate.
I knew Luna was prone to sinus arrhythmias, but I didn't expect it to be this pronounced.
Also, since the oxygen saturation level remains almost constant both when inhaling and exhaling, it means that there is always a lot of oxygen in Luna's body.
Attaching an electrocardiograph can lead to new discoveries.
Finally, I asked them to hold their breath to the absolute limit.
At first, your heart rate drops sharply, just like when you take a deep breath, but it gradually starts to rise again.
Towards the end, the patient showed signs of distress, and consequently, their oxygen saturation level dropped slightly, and their heartbeat became stronger. When they reached their limit and resumed breathing, their heart rate increased sharply, exceeding 90 BPM.
Even after resuming breathing, oxygen saturation levels did not immediately rise; in fact, they decreased. This indicated that oxygen was being consumed in the body, unlike when taking deep breaths.
For the electrocardiogram and heart sounds recorded while exercising with a bag over her head, Luna performed leg raises with a bag over her head, keeping it sealed. After only about 20 seconds of exercise, her heart rate had already exceeded 100 BPM, indicating that even this seemingly simple exercise was quite strenuous for Luna, who doesn't usually exercise.
Furthermore, the oxygen inside the bag is limited, so the more you do it, the more difficult it becomes, and the amount of oxygen decreases numerically, indicating that it is being consumed by the exercise.
The patient raised their hand midway through, so we removed the bag, but their oxygen saturation continued to drop, falling sharply to 76. Their heart rate also increased to 112 BPM, suggesting their body was trying to compensate for the low oxygen level by increasing their heart rate.
My oxygen saturation level hadn't fully returned to normal, and my heart rate was still high, but they performed the test again.
Luna did an amazing job enduring such a tough procedure twice. Moreover, her oxygen saturation dropped to 71 during the second attempt, and it seemed even more difficult for her than the first time.
And there were many water droplets inside the bag that had accumulated from Haruna's breathing, so we also filmed those.
During the echocardiogram and heart sound examination, a small, squiggly mass was visible on the screen when the probe was applied. It was moving in sync with Luna's heartbeat, so it was undoubtedly Luna's heart. It was a little small, and Luna herself said, "It's surprisingly small." She also described its shape.
Finally, when we asked participants to hold their breath, their heart rate didn't seem to change much while they were holding their breath, but immediately after they resumed breathing, the heart rate became slightly more rapid for a brief moment.
Next, we used an ultrasound to examine the heart immediately after exercise.
For exercise, we ask you to do squats.
Immediately after the procedure, we had Luna sit on the bed and performed an ultrasound. It was a little difficult to see, but her heart was beating faster than before, and she said, "It might be quite fast!"
When the patient took a deep breath and exhaled slowly, their movements slowed down dramatically, and an ultrasound revealed that they were experiencing sinus arrhythmia.
For the heartbeat during masturbation, as always, she took off all her swimsuit and did it in her natural state.
Luna's pubic hair is so thick that she herself is aware it's very hairy, and it's among the thickest of all the models we've worked with so far. When you see it on video, it's like a jungle.
She has a cute face and an incredibly cute voice, but the fact that her pubic hair is thick and coarse creates a striking contrast.
After inserting the adult toy and turning it on, she involuntarily let out a gasp, and then began moaning quite intensely. Just after she said, "I'm coming," her heart rate quickened slightly as she climaxed, and after she climaxed, we could hear a sound like a premature contraction, where her heartbeat seemed to be slightly off. It appears that masturbation has put a strain on her heart.
[The content of "Heartbeat 2" begins here.]
When the stethoscope was placed on my heart, I removed my swimsuit top and was allowed to do so while topless.
The heartbeat is very clear and the heart rate is around 80 BPM.
When I positioned the device slightly higher up, the heart sounds became muffled, but the sounds of the lungs breathing were clearly audible. When I positioned it near the apex of the heart, the "thump, thump, thump" sound was amplified, and I had the impression that the "thump" part was particularly strong.
For the heart sounds while standing and squatting, Luna also listened with earphones and compared them to the heart sounds she heard while sitting (using the heart sound 1 tool) to see which was faster.
They said this one sounds a little faster.
After that, when she squatted down, her heartbeat calmed down a little, and when she stood up again, it started to pick up again immediately after she stood up, showing that Luna's heart was beating precisely in accordance with her posture.
In the section about the sound of her heartbeat when ice was applied, Luna, who was lying down with an eye mask on, had bags of ice applied to her body several times.
She already seemed anxious before the shoot even began.
They applied ice to various parts of his body, including his chest, stomach, and legs, and his body flinched each time. His reaction clearly shows just how cold the ice was. He also said that his stomach felt the coldest and was the most surprising, and indeed, the video shows him flinching the most when the ice was applied to his stomach.
Furthermore, its heart rate increased when the ice was applied, indicating a reflex reaction. When the ice was applied to its feet, its stomach also rumbled with a "gukyuuuuuuu" sound.
In the second half, he continued to hit various parts of her body in succession, causing Runa to involuntarily let out a moan, "Ahhh."
Next, we asked Luna, who isn't very fond of foot reflexology, to get on the foot reflexology massage table. She made a very pained expression, but she did her best to stay on it.
There's something alluring about seeing someone endure pain.
Immediately after getting on, her heart rate gradually increased, and when I asked if she could jump while on, she hesitated but bravely attempted a small jump, only to get off immediately due to the intense pain. Her heart rate seemed fastest at that moment. Perhaps her heart sensed that her life was in danger because of the pain. I then asked her to get on one foot at a time, but when she tried, she said, "No way, no way, no way!" and her heart rate increased again at that time.
Even so, he managed to stay on it for about three seconds, but he looked like he was in a lot of pain.
Finally, when she got on with both feet and even jumped, her heart rate had quickened again, and it was clear from her heartbeat that Luna is sensitive to pain.
The sound of her heartbeat while she was urinating indicated that she was holding it in for quite some time, so we made an urgent request and were able to film it.
We had the person stand in front of the toilet, but instead of having them urinate immediately, we pressed on their lower abdomen around the bladder to observe their reaction.
When I pressed firmly several times, she made a pained expression and her heart rate quickened. As you said, it seems she's really enduring a lot.
After that, when she sat on the toilet seat and began to urinate, the sound of her urinating was clearly audible, "trickle, trickle, trickle." When we asked her to stop once in the middle, she seemed confused and said "Huh?", but she didn't refuse and stopped, albeit with a strained expression on her face.
In the end, they finished writing all the remaining sentences and seemed relieved.
For the recording of heart sounds while smoking, we asked Luna, who smokes regularly, to smoke while we recorded her heart sounds.
Initially, my heart rate was calm, but it increased with each puff and nicotine intake, reaching a speed comparable to that of light exercise like squats by the time I finished. If you watch until the end and then watch again from the beginning, you will see the difference in speed.
When I told Luna about it after the shoot, she said she was feeling dizzy towards the end. Smoking really is bad for your health, isn't it?
But apparently, he still won't quit smoking.
In the carotid artery pulsation and heart sounds, the pulse beats in time with the heartbeat, making a popping sound.
Luna's body is also crisscrossed with countless blood vessels, and the fact that some of them are visible due to their pulsations is very fetishistic. At one point, I touched her carotid artery with my hand, and I could feel it beating with a thumping sound.
Based on various blood pressure and heart sounds, Luna, who suffers from poor circulation and cold extremities, also has low blood pressure. As expected, when measured while lying down, her blood pressure was low, especially her systolic pressure, which was below 100, lower than the average blood pressure for women in their 20s.
Next, when we measured your blood pressure while you were sitting, it was almost the same as before, consistently low. This explains why you suffer from cold extremities.
When we measured the heart sounds after exercise by compressing the chest, we found that when we compressed the chest immediately after a squat was completed, we could feel the heart beating at approximately 120 BPM in our palms.
Midway through, when I pressed on the camera with my other hand, the camera shook in time with my heartbeat. I hope you can feel Luna's heartbeat through the shaking of the video.
The heart felt like it was resisting strongly and had a strong pulse during compression, but it gradually calmed down after the compression was released. I also compressed it one more time at the end.
During the phonocardiogram recording, Luna placed the probe herself and listened to the Doppler sound. The Doppler sound was clearly audible through the phonocardiogram, and Luna's heartbeat resonated throughout the room. When listening with a stethoscope, you need to wear earphones to hear, but this is not the case with a phonocardiogram, so if there are people around, everyone can hear it.
They commented on the sounds they heard, saying things like, "That's a dull sound!" and "Something's strange!", pointing out the differences between those sounds and those heard with a stethoscope. They also told me which sound they preferred: heart sounds or sounds from a stethoscope.
Also, when you hold your breath, the sound will initially be slow, just like when listening with a stethoscope, but it will gradually speed up, and when you resume breathing, it will become even more intense.
At that time, Luna said, "Has it gotten faster?" and also described the Doppler sound in an interesting way.
Finally, when I asked the patient to take a deep breath, the sinus arrhythmia was very clearly discernible on the phonocardiograph, with the speed of the sound being completely different when inhaling and exhaling. When exhaling, it was so slow that I thought it might stop, but when the patient inhaled again, it sped up dramatically, to the point where I could tell whether they were inhaling or exhaling just by listening to the Doppler sound.
The electrocardiogram and heart sounds during masturbation allow you to see the heart rate and waveform on the electrocardiogram while simultaneously listening to the actual heart sounds with a stethoscope. The electronic sounds from the electrocardiogram are also audible at the same time as the heart sounds heard through the stethoscope, ensuring a perfect synchronization.
After she answered some rather sensitive questions, when I applied the electric massager, her heart rate, which had been around 86 BPM, suddenly skyrocketed to 100 BPM, and her heartbeat became a loud "thump, thump, thump," clearly indicating she was feeling it intensely. Just when I thought it had dropped a little, it rose again, and when I asked her later, she said she felt it whenever her heart rate was elevated. By looking at her heart rate, I could tell exactly when Luna was feeling good.
At the end, she came right after saying "I'm coming...", and my heart rate shot up immediately. It continued to rise for a while even after she finished coming, and combined with Luna's heavy breathing, it was, to put it mildly, incredibly erotic.
