Thank you for viewing.
This is the first heartbeat of Tsuki-san, age 25.
She had a pure and gentle aura, possessing both elegance and cuteness. Her looks were, of course, cute, but above all, she had a soothing, soft voice that was calming just to listen to.
Apparently, she usually works at a cafe, and if there was someone as lovely as her working there, I'd definitely go to that cafe every day.
They worked incredibly hard during the filming, especially during the exercise scenes, giving it their all and letting us hear the pounding of their heartbeats as they pushed themselves to their limits.
I'm grateful to Natsuki for her hard work.

The video is 51 minutes and 57 seconds long.
After a brief self-introduction, when I placed the stethoscope on Tsuki-san, who seemed a little nervous, I could hear her heart beating at approximately 81 BPM, "thump, thump, thump, thump."
To the question, "If your boyfriend had a heart fetish, would you let him listen to your heartbeat?", she said she would. If by some miracle I could become Tsuki's boyfriend, I would listen to it every day.
We also asked them to answer questions such as, "How does it feel to hear your own heartbeat?" and "Have you had any heart-pounding moments recently?"
Next, they were asked to listen to their own heartbeats.
After placing the stethoscope and listening for a while, they said, "It seems slower than I expected."
When I ask them, "How do you feel when you hear your own heartbeat?", they reply, "It's a strange feeling."
Afterward, we change the position of the stethoscope and ask you to listen for any differences in how the heart sounds are heard.
Also, after drinking water, his heart rate increased slightly.
Finally, I had her take a slow, deep breath. When she inhaled, her heartbeat quickened slightly, and when she exhaled, it slowed down. Her heart rate changed in sync with her breathing, indicating sinus arrhythmia. Tsuki also shared her thoughts at that time.
When I pressed on his chest, his heartbeat was faster than before because he was standing. When I had him stand with his back to the wall and I pressed on his chest with my hands, his heartbeat became even faster, reaching about 130 BPM, as if he had just exercised. You can tell from the speed of his heartbeat that he is desperately resisting the external pressure. He occasionally made a pained expression on his face as I pressed on relentlessly with my entire body weight.
When I stop applying pressure, her heartbeat slows down slightly, but as soon as I apply pressure a second time, her heartbeat speeds up again. Her heart doesn't get a moment's rest. The second time, I zoomed in on her chest area, and you can see my hand shaking as Tsuki's heartbeat pulsates during the pressure. Tsuki has a gentle and calm personality, but contrary to that, her heart beats very strongly, and that contrast is irresistible. I could feel the pulse in my hand.
Finally, when pressure was applied one more time, the heartbeat became rapid again, and even after the pressure was released, it remained fast for a while before suddenly slowing down.
The sound of her heartbeat during the squats indicates that she is doing them very intensely. Her heartbeat, which was slow at first, has become very fast due to the intense squats, and her expression shows that she is in great pain, breathing heavily, and it is clear that she is squatting at her absolute limit. Tsuki also hears her own heartbeat and says, "It's getting faster!" Immediately after finishing the squats, her heart is beating at about 140 BPM, and you can hear her heart desperately pumping oxygen throughout her body.
Tsuki-san, breathless, commented on her own heartbeat, saying, "It's so fast, haa haa."
When she placed her hand on her chest, she could feel her heart beating strongly, and while trying to control her heavy breathing, she gave her feedback.
Finally, we asked the patient to take deep breaths to calm their heartbeat. Their rapidly beating heart didn't calm down easily, and they repeatedly took deep breaths, desperately trying to soothe it.
Even the sound of her heartbeat after step-ups shows how hardworking Tsuki is, and she is doing the step-ups with all her might, saying, "It's a little tough! It feels like climbing stairs!" Her heartbeat is getting faster and faster, and in the last 30 seconds she is doing it at full speed, and her heart is beating even faster. At its peak, her heart rate is up to about 150 BPM, and it's at a speed where you might think her heart is going to jump out of her chest with a "thump, thump, thump, thump" sound.
I also had Tsuki-san listen to the sound and give me her feedback.
My heart rate seems faster during this than during squats, but it seems that Tsuki-san felt her heart rate was faster during squats than during this.
Also, recovery was faster with this method; taking deep breaths helped calm down more quickly than with squats. It's interesting how even with the same exercise, squats and step-ups can change Tsuki's heart rate and recovery time.
To measure her heart rate while holding her breath after exercise, we had her do step aerobics to speed up her heart rate before she held her breath. She was out of breath and breathing heavily after the exercise, but there was no time for her to catch her breath, so we had her lie down on the bed and I covered her nose and mouth with my hands while she held her breath. I was wearing rubber gloves so it was a tight seal, and she would immediately raise her hands to indicate that she couldn't do it anymore because it was so hard to breathe, but I had her persevere and hold her breath for a while. When I let go of her hands, she was breathing frantically with a desperate look on her face, which was unimaginable from the gentle Tsuki-san I knew. However, I would immediately cover her nose and mouth with my hands again, and this was repeated several times, so it truly felt like Tsuki-san's life was in my hands.
Perhaps because of these strenuous activities, at around 38 minutes and 46 seconds, you can hear the sound of a heart beating in what appears to be an irregular rhythm: "thump, thump, thump-thump, thump."
Also, while holding her breath, her heart rate slowed down so much that it seemed like it might stop at any moment. It's a charming contrast to how her heart rate was doing the opposite of what should have been needed to deliver lots of oxygen to her body after exercise.
For the echocardiogram and heart sounds, we placed the ultrasound device on Tsuki's chest to observe the movement of her heart. The moment the ultrasound device was applied, she closed her eyes, seemingly finding the special gel too cold.
The heart's movement is very clear; it moves vigorously in time with the heartbeat, making it easy to understand.
When I pointed to the heart on the screen and showed it to them, they said, "Ah, that's it!" and "It's beating just like the sound!" and nodded their heads in time with the rhythm of their own heartbeats.
During the procedure, when we asked her to take a deep breath, there was a change in her heart rate, and it seemed that Tsuki-san noticed it as well. Unfortunately, the ultrasound images taken at that time were not saved, so we performed another ultrasound and included those images.
This time, Tsuki-san is performing the ultrasound herself. It's adorable to see her moving the ultrasound probe around her chest, below her left breast and towards the center, while looking at the screen to find her own heart. We could even see her heart beating. We've also included this ultrasound footage in a separate video.
In the post-exercise echocardiogram and heart sound examination, we use echocardiography to observe the heart's activity after the step-up exercise. In the main part of the video, the examination begins a little before the step-up exercise is finished.
She is breathing heavily, and you can tell her heart is beating very fast. When we apply an ultrasound, the screen shows her heart beating incredibly violently. Because it's moving so fast, it's much easier to pinpoint where her heart is than it normally would be. "It's so much faster than before!" Tsukiko says.
If you try your best to hold your breath, your heart rate will slow down, just like when you held your breath after the exercise earlier, and you can clearly see from the echocardiogram that your heart's movement has slowed down. This video shows that your heart's movement changes depending on whether you exercise or hold your breath, and that it's not constant. We have also made a separate video of this echocardiogram screen, so please take a look at that as well.
The heart sounds recorded while engaging in solo sexual activity were captured by applying an electric massager to the lower body, capturing the heart sounds at the points of pleasure and the moment of orgasm.
We begin by asking you to answer some rather sensitive questions, such as "How many times a week do you masturbate?" and "Are you easily aroused?"
Even though Tsukisan is gentle, elegant, and demure, it seems she usually does it alone, and just imagining that gets me excited, but to be able to see her like that, and even hear the sound of her heartbeat at that time, is the ultimate reward.
When she applies the electric massager to herself, she lets out sweet moans like "Mmm..." and "Ahhh." When the electric massager hits a particularly sensitive spot, her heart rate suddenly quickens, and she looks genuinely pleased, displaying an erotic expression. When she reaches orgasm, it feels so good that she orgasms twice in a row, letting out a loud gasp of "Mmm!" at that moment. You can tell she's orgasming from the speed of her heartbeat.
After it was over, she gave me her thoughts on the heartbeat, and when I asked her how she felt doing it alone at the end, she shyly said, "Did it feel good?"
Seeing such a beautiful person in such a lewd state firsthand gave me an incredible sense of transgression.
