This is a set containing heartbeat recordings 1 and 2 of Mio, age 26.
Please be careful not to make duplicate purchases.
Furthermore, it's cheaper than buying them individually.
If you wish to purchase both items, please choose this option.
I hadn't seen any photos of her face beforehand, so I was really looking forward to seeing what kind of person she would be, and I had set my expectations for her cuteness quite high. But when I actually met her, she was so incredibly cute and beautiful that she easily surpassed those expectations, and I was speechless for a moment because she was so adorable.
The sample images have been blurred, but in the full video, Mio's face is not blurred at all, so I'm sure viewers will be surprised by how cute she is.
To give you an example using a celebrity, she resembles former Nogizaka46 member Erika Ikuta, and Mio herself said that people often tell her that, and she really does look like her so much that I couldn't help but ask, "Are you Erika Ikuta?"
It just goes to show you never know what life will bring. I was so surprised to see such a beautiful person in the world, and even more so that she took an interest in my photography and reached out to me.
Not only was she cute, but she was also slender with a large bust; she was a perfect model from every angle.
Her heart rate was about average, but since she doesn't usually exercise much, she became short of breath and her heart rate increased when she did strenuous exercise.
I was able to receive nourishment that can only be obtained from the heartbeat of a beautiful person like Mio when she is out of breath.
Please note that some of the footage was filmed with the actors wearing masks.

The video is 33 minutes and 2 seconds long.
After the self-introduction, I listened to the patient with a stethoscope and heard a heartbeat of approximately 78 BPM, with no arrhythmias and a steady rhythm.
Also, since you mentioned you weren't feeling particularly nervous, what you're hearing is the natural, resting heartbeat of Mio.
At one point, she sneezed, and I felt her heart rate quicken slightly at that moment.
Even someone this incredibly cute has a heart, and just being able to hear its normal heartbeat or the beat when it sneezes is enough to excite any heart fetishist.
I also asked several questions about hearts, and when I asked if she would let her boyfriend listen to her heartbeat if he had a heart fetish, she answered without hesitation that she would.
I'm incredibly envious of anyone who gets to be the boyfriend of such a wonderful person; they get to hear his heartbeat all the time!
She also shared an experience that made her heart skip a beat, and she said that if she were to become her boyfriend, she would be able to hear the sound of his heart beating very fast.
Next, you were asked to listen to the sound of your own heartbeat.
It seems to sound surprisingly strong, but the rhythm is normal, according to her. It seems the rhythm is normal to Mio as well.
When asked about the speed of her heartbeat, she said, "I think it's fast!", so it seems that this sound sounds rather fast to Mio.
She also said that when she placed her hand on my chest, she could feel my heartbeat slightly.
I'm sure if I could become Mio's boyfriend, I could put my hand on her chest and feel her heartbeat.
My imagination is running wild.
I asked the patient to move the stethoscope from the pulmonary valve to the aortic valve and then to the apex of the heart, and to listen to the differences in how the heart sounds were perceived.
It was said that the area around the pulmonary valve was easier to hear, but it was also said that the aortic valve and the apex of the heart were both easily audible when the stethoscope was placed there.
If you listen carefully, you can certainly hear a "thump, thump" sound around the pulmonary valve, but the "thump" sound is more audible than the "thump" sound around the aortic valve, and conversely, the "thump" sound is more pronounced around the apex of the heart.
Because they are slender, it's easier to notice the difference in how their heart sounds.
I also asked Mio where the sound is clearest, and she answered my question.
You can also see that when you drink water, your sympathetic nervous system is stimulated, causing your heart rate to increase.
Finally, we had Mio take a deep breath, and while she was inhaling, her heart rate didn't seem to change much from the normal speed. However, when she held her breath and then exhaled, her heart rate was noticeably slower and more pronounced.
It seems that Mio's heart rate changes more easily when she exhales or holds her breath than when she inhales.
For the heart sounds during squats, we had Mio perform squats for two minutes, and she listened to her heart sounds during that time.
Also, to prevent the stethoscope from shifting, we attached a support to our chest and placed the stethoscope between the support and the support while taking the picture. It seems to produce relatively less noise compared to using your hand.
Up until now, we've heard the sound of her heartbeat while she was sitting, but here we start from a standing position, so her heartbeat is faster than before. Even just listening to this, you can tell it's fast, but for Mio, who doesn't exercise regularly, two minutes of squats is enough to make her heart beat faster. Her heartbeat gradually gets faster during the squats, and after she finishes, it's even faster, reaching about 110 BPM, and she's out of breath. Even though it doesn't look that strenuous in the video, it seems that even a little exercise is tough for Mio, who doesn't exercise regularly.
After listening to their own rapidly beating heartbeat and sharing their impressions, they were asked to take a deep breath to calm their heart rate.
Next, we asked them to hold an air squat position for one minute.
Although it's a short one minute, maintaining the most challenging position is even harder than the squats we did earlier, and you can see how difficult it is from his expression.
While you're doing the air squat, your heart rate doesn't seem to increase dramatically, but once you stand up afterward, it suddenly becomes much faster. It seems Mio is the type of person whose heart rate increases immediately after exercise. Is this because you don't exercise regularly?
Mio also said that her heart rate was faster this time than when she did the squats earlier, suggesting that being in a strenuous position makes her heart rate up.
Next, we had them do an even more intense step-up exercise.
Since we've been exercising continuously up to this point, Mio is quite exhausted, and she even said that this was tougher than what we were doing, but she still persevered and did it for the designated time.
I can see that the heartbeat is gradually getting faster compared to when I first started, and the sound itself is also getting louder.
That level of physical activity must mean the heart is pumping out a lot of blood.
Immediately after the session, I handed him earphones so he could listen to his heartbeat, and he said, "I think it's the fastest it's ever been!" His heart rate was around 120 BPM, and the sound of his heart was so intense that it sounded like his valves were opening and closing ****fully.
She was also out of breath, saying "Hoo, hoo," and just seeing such a cute girl out of breath was exciting.
When I asked her to put her hand on her chest, she said, "I can really feel it!" Although I'm not Mio's boyfriend, I discreetly placed my hand on her chest and could really feel her heart beating, thump, thump. Being able to feel not only the sound but also her heartbeat was the best reward.
Also, when she did squats, we observed that her heart rate increased immediately after finishing, but that wasn't the case here. It seems this speed is the limit of Mio's heart rate.
When we asked him to sit on the sofa to calm his heartbeat, we could even hear his stomach rumbling, suggesting that he had worked up an appetite from all the exercise.
After she sat there for a while, her heartbeat began to calm down, and when she lay down again at the end, it became a very slow "thump, thump, thump," sound like the valves of her heart opening and closing gently. It was almost unrecognizable as Mio's heartbeat compared to immediately after exercise.
When I compressed her chest, I could hear her heartbeat. I am larger in physique and heavier than her, but I was using my entire weight to compress Mio's heart as if I were crushing it.
My hand, which was pressing down on her heartbeat, was shaking regularly in time with her heartbeat, and when I held the camera with my other hand while pressing down, Mio's heartbeat was transmitted to the camera and it was shaking as well. You could clearly see the movement of Mio's heart, and when I asked her about it later, she said it was painful, and in the video you can see that she was having trouble breathing. I must have been putting in a considerable amount of ****.
Furthermore, perhaps as a result of the continued pressure, the heartbeat gradually quickened, suggesting that the heart was being pushed to its limits.
Conversely, when the pressure was released, the heartbeat slowed down immediately, but on the second and third releases, it became stronger and faster. The heartbeat varied even with the same pressure, making it a heart that made me want to compress it again and again.
For the electrocardiogram and heart sound test, Mio-san attached the electrodes for me.
Initially, the electrodes may come off, but once you reattach them, you will hear the electronic beeping of the electrocardiogram in time with your heartbeat.
While listening to the sound of a heartbeat with a stethoscope is nice, these electronic sounds are also very appealing to my fetishistic side.
The displayed heart rate is around 60 BPM, which might be because she's lying down, but it seems low for someone of her size. It's even lower than the average heart rate for women in their 20s.
At the same time, we also measured her oxygen saturation, which was fine, indicating that Mio has plenty of oxygen in her body.
From here, I asked you to take a deep breath and to check if there was any change in your heart rate.
Next, with the electrocardiogram still attached, I asked the patient to raise their legs and hold that position for one minute.
According to Mio, this was more difficult than the air squat exercise she did earlier.
He put his feet down a couple of times during the run, but he quickly put them back up and kept going.
Looking at the electrocardiograph's heart rate readings, it started to rise from the moment it began, reaching a peak of 82 BPM.
While intense exercises like step aerobics are good, it seems that even just maintaining the same posture for a long time can raise your heart rate this much.
Next, they were asked to do leg raises while wearing a sealed bag over their heads.
Earlier, you were simply holding your legs up, but here, you're performing a cycling-like motion inside a sealed bag where oxygen levels are decreasing, so you're experiencing a different kind of discomfort.
Although she put her feet down several times during this time, the oxygen inside the sealed bag was being consumed rapidly within Mio's body, and her oxygen saturation level only dropped slightly, even at a low of 96. However, this seemed to be enough discomfort for Mio.
My heart rate has also increased, exceeding 90 BPM, probably because my body is trying to compensate for the reduced oxygen supply. It's a vicious cycle.
When the **** raised its hand, we loosened the bag, and it appeared to be taking in a full lung capacity of air. However, we immediately resealed the bag and had it perform strenuous exercise.
Next, we used an echocardiogram to examine Mio's heart in real time.
When the probe is applied, the ultrasound screen shows a heart that, depending on how you look at it, resembles a heart. It's about the size of Mio's fist, so what we're seeing is probably her actual heart.
Furthermore, its movements are described as contracting around the "thump" part of the heartbeat sound, expanding around the "thump" part, and then twitching or jerk-like, if we were to describe the movement with sound effects.
After Mio-san looked at her own heart and shared her impressions, she held her breath, and we could clearly see her heart. When she resumed breathing, we could also see that it was beating faster.
Next, we applied the probe after exercise and examined the heart with an echocardiogram.
The video starts with the probe being applied after the exercise, and it's beating faster than before. You can see her heart on the echocardiogram screen, and you can tell that she's quite exhausted from the exercise as she gives her impressions while out of breath.
When I asked them to take deep breaths, I could clearly see that their heart rate slowed down dramatically as they exhaled slowly.
These ultrasound images are presented as separate videos, and we've also combined the ultrasound images from normal conditions and after exercise into a single video, so please compare the difference in speed.
Finally, we were able to listen to Mio's heartbeat while she was masturbating.
Even Mio, who is as cute as an idol, apparently does naughty things like this, and she answered the question of how many times a week she does it. Just imagining her doing it in this scene is already exciting, but the fact that she will now perform such a shameful act that can only be done in such a private space, and in a completely nude state with her swimsuit off, makes me feel excited too.
Perhaps it was because she moved her body when taking off her swimsuit, or perhaps it was due to embarrassment, but her heart was beating a little faster. Seeing Mio's body like this, with nothing to hide, it was truly beautiful, with a slender waist and large breasts, and I couldn't help but be captivated by it.
When adult toys are applied to her genitals, she occasionally lets out sighs and seems to be enjoying herself.
Partway through, her heart started beating much faster, and the speed of it made it seem like she was about to come any minute. Just as I expected, a little while later she said, "I'm about to come! I'm coming!" and immediately after, her body twitched as she came. The speed of her heartbeat made it clear that she had truly come.
That's way too erotic.
I think I've used up all my luck for this year, since such a beautiful woman did something naughty for me at my request.
[This is the content of Heartbeat 2.]
First, we had you listen to your heartbeat while you were standing.
Mio also experiences a faster heartbeat when standing than when sitting, with a heart rate of around 90 BPM.
When she crouched down, she slowed down and said, "Sorry for the delay!"
Conversely, when she stood up, we could see that her heart rate increased after a few seconds, so we could see that Mio's heart changes in this way when she sits down and stands up.
In the section where the heart sounds are heard when the stethoscope is placed on Mio's chest, the video is presented in a first-person perspective, showing me placing the stethoscope I'm holding on Mio's chest and listening to her heartbeat.
If someone this incredibly cute came to the hospital for a checkup, I might end up listening to their heartbeat the whole time.
If I thought about it that way, I'd like to start studying now and become a doctor. But that's impossible, isn't it?
At least during the filming, I was able to listen to it in a way that resembled a medical examination, and my dream came true.
Also, since she's taken off her swimsuit top and is topless, your eyes will likely be drawn not only to her heartbeat but also to her breasts.
After placing the stethoscope near the center of the chest to listen to the heartbeat, I also placed it on the upper right and upper left sides, and in addition to the heartbeat, I could hear the breathing sounds. The respiratory rate was about 16 breaths per minute, which is about average, and I didn't notice any particular abnormalities. Finally, I placed the stethoscope near the lower part of the breast and listened to the heartbeat at the apex.
Based on the sound of her heartbeat while she was on the foot reflexology massage table, she didn't look like she was in pain right after getting on, but when I asked her, she said, "It hurts! It really hurts!", so it seems she was feeling the pain. Mio seems to have a poker face.
What's more, not only does my facial expression seem to change, but my heart rate also seems to slow down a bit right after getting on the bike, rather than speeding up. It's strange, isn't it?
I asked her to squat down right there, and she said, "No way, I can't!" but she did squat down partway, and she had a pained expression on her face, so it seemed like she was really feeling the pain. Just seeing a cute woman in pain and with such a pained expression makes me grin.
I also asked them to stand on it one foot at a time, but they couldn't do that either because it was too painful.
For the heart rate measurements during arm-raising exercises, participants were asked to lift a 2-liter water bottle 20 times, and their heart sounds were recorded during this exercise.
In addition to exercises that put stress on the legs, such as squats and step-ups, I'd like to incorporate exercises that put stress on the arms like this into my routine from now on.
As the participant raised their arms repeatedly, their heart rate increased with each repetition, and each individual beat seemed to become stronger.
For the prank game, which involved listening to people's heartbeats, the game was a fishing game where participants had to fish until only one fish remained before being bitten by a shark. If they were bitten along the way, they would face a penalty game.
There are 12 fish in total, and if you pull on one of them midway through, you'll get bitten, so it's practically an impossible game.
We had the procedure done twice in total. The first time, the dog got bitten about halfway through, and the dog said, "That was a surprise!" and its heart rate seemed to have increased slightly.
He got bitten again almost immediately the second time, so a **** game is definitely in order.
I got to try the electric shock pen.
The moment I pressed the button, she seemed more surprised than when she was bitten by a shark, and it seemed like she was the most excited she'd been during the entire shoot. She looked absolutely adorable.
We measured various blood pressure levels and heart sounds while the patient was sitting, lying down, and standing.
She looked beautiful, her heart sounds showed no irregularities, and she was in perfect health. Her blood pressure was no exception; when measured while sitting and lying down, it was around the average for someone in their 20s, and she was delighted, saying, "That's great!"
However, when we had the patient stand up and measured their blood pressure, it showed "high blood pressure." Not only was the systolic blood pressure elevated, but the diastolic blood pressure was about 30 points higher than when they were sitting or lying down.
I was surprised that her blood pressure rose so much just from standing up, but what surprised me most was that such a cute person's blood pressure was being flagged as high.
For the heart sound monitoring, we had Mio hold the heart sound monitor and apply the Doppler effect herself.
The distinctive sound of Doppler echoes throughout the room, and the person listening commented, "It's so loud! It's so realistic!" describing the difference in sound compared to what you hear with a stethoscope.
I wonder if it would sound something like this if we took Mio's heart out of her body.
When you hold your breath, the sound becomes quieter and slower, but when you resume breathing, the sound becomes louder and faster again.
Furthermore, if you also do squats, the speed gradually increases as you do them, and by the time you finish, it's extremely fast, and the sound is quite loud, reaching noise levels.
It was so loud I thought the heart monitor might break, and I'm sure it was clearly audible to everyone outside.
When I asked them to take a deep breath at the end, the sound gradually became quieter, but it was still much louder than when I first touched them, which probably means their heart was beating much more vigorously.
When measuring heart sounds during chest compressions after exercise, we have the participant perform step-ups to increase their heart rate before compressing their chest.
Before this photoshoot, you did step-ups many times, and also squats, arm raises, and air squats—you probably did more exercise than you have all year, right?
Also, since they haven't eaten anything before the recording of their gastrointestinal sounds, I think they're probably at their physical limit.
After the step-ups were finished and her heart had exceeded its limit of approximately 120 BPM, I pressed down on it from directly above, and I could feel the heartbeat thumping in my hand! And what's more, it was the heartbeat of the incredibly cute Mio, so I received yet another unparalleled reward.
When the camera is held and pressure is applied, the screen shakes in time with Mio's heartbeat. I think you can feel the movement of Mio's heart through the shaking of the video.
Also, in heart sound 1, the heartbeat calmed down when the patient sat up or lay down after stepping up and down, but in this case, we were applying pressure that sped up the heart's movement, so the heartbeat did not calm down and remained fast the whole time.
That much pressure, especially after exercise, must be putting a lot of strain on the heart.
After releasing the pressure, her heartbeat calmed down a bit, but I applied pressure one last time to finish her off.
In the carotid artery pulsation and heart sounds, the area near the base of the left side of the neck, towards the back, can be seen twitching in time with the heartbeat.
You can see the pulsation, so I imagine a tremendous amount of blood is flowing through with each contraction of the heart.
You can't usually get this close to a woman's neck on a train or anything like that, so I'm grateful to be able to see it like this.
For the electrocardiogram and heart sound measurements while holding your breath, we ask you to hold your breath for one minute and observe the changes in your heart rate during that time.
My heart rate was around 69 BPM before I stopped breathing, but it dropped slightly the moment I held my breath.
That's a diving signal. It's risen slightly from there.
I told you to hold your breath for one minute, but it seems that holding your breath for a minute is quite difficult for Mio, as she ends up breathing in between. She probably has a low lung capacity. Please also pay attention to her heart rate during that time.
If you hold your breath again immediately and then breathe as soon as the timer goes off, your heart rate will rise sharply and exceed 70 BPM.
They must have been in a lot of pain.
When I asked if he could hold his breath for two minutes, he said, "No way!"
I couldn't even hold my breath for a minute, so if I were ****d to hold my breath for two minutes, my heart rate would probably go through the roof.
Finally, we ask participants to masturbate while wearing an electrocardiogram, and we monitor the changes in their heart rate during this time.
Not only do I get to witness such a beautiful woman masturbating, but I also get to see her heart rate in real time, so I'm sure I've used up all my luck not just for this year, but for my next life as well.
When the vibrator is applied, my heart rate initially drops, then rises again, and then drops again very quickly.
I guess it depends on how you aim it.
She let out a breathy moan, and finally, after saying "I'm about to come," she quietly reached orgasm, her heart rate slightly elevated at that moment. Judging from the speed of her heartbeat, it's possible that Mio was more sensitive to the adult toys used in Heartbeat 1 than to the vibrator.
Even so, when you hit the target, your heart rate increased, and you clearly felt it.
