Mai's Heartbeat 1

* This work is fictional, and all persons appearing in it were 18 years of age or older and were filmed with their consent.

Thank you for visiting.
This is video 1 of Mai's heartbeat, 23 years old.
When I first met him, he looked so young that I thought he was a student.
I checked her age and was relieved to find that she was indeed 23, but even so, if I saw her on the street I'm sure I would mistake her for a student.
Also, when she laughs occasionally, her smile is as cute as an angel.
She was slim, standing 152cm tall and weighing 43kg, so when I touched her chest with pressure, it was very easy to feel her heart beating.

The contents are:
・Self-introduction and heartbeat
・How do you feel when you hear your own heartbeat?
- The sound of your heart when you squat
- Heartbeat during and after stepping up and down the platform
- Heart sounds when chest is compressed
- Heart sounds when compressing the chest after exercise
Echocardiogram and heart sounds
・Post-exercise echocardiogram and heart sounds
- Heart sounds when exercising with a bag on your head
・The sound of your heart when you're doing that
The video is 56 minutes and 18 seconds long.

First, we would like you to introduce yourself.
It was her first time doing a shoot like this, and even when introducing herself, she seemed nervous. Her heart rate was around 80 BPM, and Mai herself said, "I'm a little nervous." She also answered a few other questions.
Next, we asked them to listen to the sound of their own heart.
It was as if he was hearing his own heartbeat for the first time, and he said, "It's not what I expected."
We also place a stethoscope around the apex of the heart and ask the patient to comment on whether there is any difference in how they hear.
He also touched my carotid artery to check that it was properly linked to my heartbeat.
After that, we asked them to hold their breath and listened to the changes in their heartbeat.
Mai also seemed to notice that her heart was beating a little faster.
Finally, we had them drink something and listened to the changes in their heartbeats.
We also placed a stethoscope on the patient's throat and asked him to drink another drink, and we could hear the sound of him gulping it down his throat.

Next, we will listen to the sound of your heart when you do squats.
His heartbeat has gradually become faster as he does squats, and he says it's "getting a little faster."
After the squats, he listened to my heartbeat for a while, and I commented, "It feels a little faster than at the beginning." He also touched my carotid artery and gave me his impressions.

This time we had them step up and down the ladder.
Even while you are climbing up and down the step, we listen to your heartbeat with a stethoscope and can hear it getting faster.
Mai also said "It's hard" as she stepped up and down the step stool, and the proof was in her extremely fast heartbeat.
Immediately after it finished, her heart was beating at about 150 BPM, and it was pumping like crazy. I put my hand on Mai's chest, and I could immediately feel her heart beating so hard it felt like it was literally going to jump out of her chest.
When Mai listened to this sound, she said, "The rhythm has changed."
He also mentioned that when he held his breath, his heart rate slowed down. Finally, he had me take a deep breath to calm my heart rate.

When we practiced the heartbeat by compressing the chest, telling them how hard we should compress, they were initially surprised by how strong it was.
In the video, the same **** is applied with great pressure, and Mai looks like she is in pain.
Also, my hand as I was applying pressure was swaying in time with Mai's heartbeat, so I could hear her heartbeat not only by sound but also by sight.
When the pressure was released, the heart regained its strength and began beating strongly.

This time, I had my chest compressed after exercise.
After having her step up and down, I started applying pressure, and I could clearly feel Mai's heartbeat, which was now beating much more violently than before, transmitted to my hands, which was a real treat for me. I could also see in the video that my hands were shaking violently as I was applying pressure, which I could see was linked to the sound.
Also, at around 32 minutes and 48 seconds when the pressure was released, we heard a "thump, thump, thump, thump, thump, thump, thump" sound, and we could hear a momentary disruption in the rhythm, which may have been due to a premature contraction.
This kind of heartbeat from young people is extremely valuable.

With the echocardiogram and heart sounds, when we place the probe we can hear the rhythmic thumping of Mai's little heart beating.
Mai also seems to be able to understand the movement of her own heart.
When I asked him what shape it looked like, he said it looked like a heart.
Furthermore, when we had them wear earphones and placed an echo sound on them, it seemed that they could see that it was linked to the sound. We also confirmed that their heartbeats became faster when they stretched during the session.

Next, we checked the heart after exercise with an echocardiogram.
When we placed the probe on her heart, which was beating hard immediately after she stepped up and down the step, we could see her heart beating incredibly fast, desperately pumping blood around her body.
Mai was out of breath and said, "It's going pretty fast, I'm panting." Her heartbeat gradually slowed down, but at one point she started coughing, and I could see her heartbeat speeding up again.

To measure the heart rate while exercising with a bag over your head, participants lie on a bed, put a bag over their head to seal it, and then perform exercises that move their legs like pedaling an air bicycle.
Mai was working really hard and raised her hand once during the exercise, so we loosened the bag, but we quickly resealed it and she continued exercising.
His heartbeat was slow at first, but it gradually became faster, and it was apparent that he was having difficulty breathing. Towards the end, he seemed to be hyperventilating, and we decided it was too **** to continue, so we removed the bag. At that time, his oxygen saturation level was recorded at 63, which is an extremely **** number.
I was in a daze for a while after I took the bag off.
Finally, the bag is photographed, revealing a thin layer of water droplets caused by heavy breathing.

Finally, I recorded the sound of Mai's heart beating when she performed some naughty acts on me.
When I first answered some slightly sensitive questions, my heart started beating faster, perhaps because I was embarrassed.
Then they used an electric massager on me.
While I was touching her, her breathing became rough and she was making sexy sounds like "hmm". Her heartbeat was also getting faster and faster, and she was completely feeling it.
Towards the end, her body was twitching and convulsing as she reached orgasm.
Finally, we asked her to tell us about the changes in her heartbeat and how she felt when she reached orgasm.
