Thank you for visiting.
This is a video of Natsumi's heartbeat, 25 years old. She usually works at an izakaya.
She is a very lovely person, and in one word, I think she can be summed up as "innocent."
He was always smiling and his eyes were sparkling, and as you would expect from someone who works at an izakaya, he was very easygoing and fun to talk to.
It's the complete opposite of me.
I thought that if I had a boyfriend like that, every day would be fun.
Also, because he was slim, it was very easy to hear his heartbeat.
The content of the shoot we asked Natsumi to do was as follows:
・Self-introduction and heartbeat
- How do you feel when you hear your heartbeat under normal circumstances?
- Heartbeat when taking a deep breath
Heartbeat when lying down
- The sound of your heart when you squat
- Heart sounds when chest is compressed
- Heart sounds during and after exercise
Carotid artery pulsation and heart sounds
Heart sounds during examination
- Heartbeat during masturbation
The video playback time is 44 minutes and 12 seconds.
During the self-introduction and heartbeat session, we asked each person to state their name and then listened to their heartbeat.
When asked if he was nervous during the race, he replied, "A little bit," and his heart rate was about 94 BPM, so he must have been nervous.
When asked what he thought of hearing his own heartbeat, he said, "Oh, it's scary," as it was the first time he had heard his own heartbeat.
His reaction when he heard it for the first time was genuine surprise, and his expression was really cute.
It has also been said to make an amazing sound.
They also listened to the sounds of the lungs, and when they heard the ``buzzing'' sound that was heard when breathing, they said that it was the ``sound of air.''
We also asked them to listen to the heartbeat when they held their breath.
Her expression when she's stopped is also cute. This girl is cute no matter what she does.
He also mentioned the change in the sound of his heart at that time, saying, "It's gotten faster!"
Finally, he touched my carotid artery and shared his impressions of the experience.
Next, we asked them to take a deep breath and listen to the sound of their heart.
I taught him how to take deep breaths by inhaling through his nose for four seconds, holding it for five seconds, and then exhaling slowly over eight seconds, and he followed those instructions carefully.
I also told him to listen carefully to his heart rate, as it changes when he inhales and exhales. He seemed to notice the difference in speed, and said, "Maybe it's faster when I inhale." After that, I asked him to continue taking deep breaths for a while.
Next, I asked him to lie down on the bed and listened to the sound of his heart while he was resting.
My tension seems to have calmed down considerably, and my heart rate has dropped to 63 BPM.
At one point, we also asked them to raise both arms as high as they could and stretch.
Your heart rate, which had been slow at "dock, dock, dock, dock," has increased and you can see that it has clearly become faster, at "beat, beat, beat, beat, beat."
Natsumi seemed to understand this as well, saying that she had become "faster."
Also, as she stretches, Natsumi's ribs are visible, and as she raises her arms, her beautiful, defenseless armpits are also visible, which is another highlight.
We asked them to try their best for two minutes while listening to the sound of their heart when doing squats.
Natsumi, who doesn't exercise regularly, can be seen to have her heart gradually increase in speed and beat faster. The less exercise you do, the greater the increase in your heart rate.
At some point, they say, "Oh, this is hard."
By the end of the two minutes, the sound has gotten incredibly loud.
The heartbeat is not a "thump thump" but a "thump, thump, thump, thump" sound, and you can hear the heart valves moving vigorously.
Natsumi also said, "It's really fast."
I had him take some deep breaths, but his heartbeat still didn't calm down and he said it was still "fast."
It finally calmed down towards the end.
In terms of the sound of her heartbeat, I compressed her chest three times. While I was compressing Natsumi's chest, I could hear my hand pushing back and twitching in time with her heartbeat, which had sped up a little. I could see her heart beating desperately through my hand. During the second compression, I took a close-up video of Natsumi's chest, so it was even clearer.
You can also hear the "whoosh, whoosh" sound of blood flowing while you apply pressure.
For the "Heart sounds during and after exercise" section, we had the participants step up and down on a step for 2 minutes and 30 seconds, and we recorded their heart sounds while they were exercising.
Just like the sound of your heart when you do squats, you can hear your heart beating slowly at first, but gradually getting faster. What's more, the amount of exercise is far greater than with squats, so by the time you finish stepping up and down the step, your heart is beating wildly, "Bam, bam, bam, bam, bam, bam, bam, bam." Your heart rate is probably at a maximum of 158 BPM.
Natsumi also listened to her own heartbeat and was out of breath, saying, "Haa haa, it's so fast, haa haa."
At one point, the doctor put his hands on my chest and touched my carotid artery, and I was asked to share my impressions.
We asked him to hold his breath, but since his breathing was rough after the exercise, he was unable to hold it for long and looked very uncomfortable.
Finally, I asked him to take a deep breath and calm his heartbeat.
In "Carotid Artery Pulsation and Heartbeat," we can see the mole on Natsumi's neck twitching. The blood pumped by her heart pulsates through the carotid artery, and it really made me realize that Natsumi is still alive.
For "Heartbeats During an Examination," we had her wear a cute sweater with a picture of a rabbit on it, and we had her come to the hospital for an examination, so we could take her heartbeat. Of course, this outfit is Natsumi's own clothes. It's really exciting to see such a cute girl in the examination room. She was also wearing heat tech underneath the sweater, but we had to tuck that up so we could use the stethoscope to listen to her underwear.
I carefully examined the center of the chest, the right lung, and the left lung.
Also, since it was my first shoot, I was extremely nervous, and my heart was beating fast.
To record the sound of his heart when he masturbated, we had him use a vibrator on him and recorded the sound of his heart right up to the point of orgasm, and we also had Natsumi listen to the sound of his heart at that time.
At first, her stomach growled a few times and she laughed, but gradually her face started to look like she was enjoying it, and about two minutes after I applied the vibrator she said, "Oh, I'm coming..." followed by "Ah," and then she came.
It's rare to hear the sound of a cute girl's heart beating when she's climaxing, so it's extremely precious.
