Thank you for visiting.
This is video 1 of Riko's heartbeat, 30 years old.
She was short and petite, standing 153 cm tall and weighing 43 kg.
She regularly works out at the gym and does Pilates, so she has a slim figure, blonde bob hair, and a sexy, cute, gal-like look. However, she also describes herself as a laid-back person who goes at her own pace, and she speaks with a gentle manner and polite language, creating a wonderful contrast between her appearance and personality.
This time, I was interested in it and was able to take some photos.
I'm very happy that there are people like Riko who are interested in heart fetishes.

The video is 51 minutes and 32 seconds long.

First, she introduces herself, then I place a stethoscope on her left chest and listen to her normal heartbeat while she is sitting. Although she has large breasts, I can hear her heartbeat clearly, and although she seems to be nervous, her heart rate is 66 BPM, which is relatively slow. Riko's heart is just as gentle as its owner.
If you place the stethoscope around the lower part of your breast, you can clearly hear the apex of your heart beating, one beat at a time, as if you were placing your ear directly against your chest.
During the test, we also asked a few questions about the heart, such as, "Why did you decide to have this scan?"

Next, we asked Riko to listen to the sound of her own heart.
Apparently, she had heard her own heartbeat with a toy stethoscope before, but this was her first time using the real thing.Of course, the real thing sounds better, and as she listened to her own heartbeat, she described it with cute sound effects, saying, "It goes, 'pek, pek, '."
At one point, the doctor placed the stethoscope around the apex of the heart and Riko seemed to notice the difference in the sound, saying, "It has a deeper quality."
As the doctor touched his carotid artery and listened to his heartbeat, he was confused and said, "I think my carotid artery is faster." "But are they the same?" "No, I think my carotid artery is faster." It was heartwarming to see him.
After drinking the water, his heartbeat became faster and stronger, and he was surprised at how fast his heartbeat was, saying, "Wow, it's so fast!"
Finally, we had her take a deep breath. The rate at which Riko's heart beat changed slightly when she inhaled and exhaled, and she had a nice sinus arrhythmia.

Next, we had them do squats and listened to changes in their heart sounds.
Each exercise is done with a firm load, and Nariko's heart rate is gradually increasing.
Because my heartbeat was slow before I started, the changes are easy to see and each beat seems to be getting stronger, as the heartbeats are getting much louder.
"Wow, it's getting faster!" she exclaimed, surprised at how fast her own heart was beating, and after two minutes of squatting, her heart was beating at 91 BPM, which was clearly faster than normal. You could hear the valves opening and closing violently, "buck-buck-buck-buck," and it made me worry about whether it was okay for such a small body to do that.
He said, "It feels faster after it's over!" and even touched his carotid artery to feel the difference from normal.
Finally, take a deep breath and record until your heartbeat calms down.

After the squats, we also had them do step-ups.
Riko, who exercises regularly, seems to be okay with the seemingly difficult step-ups, but her heart is gradually beating faster than when she is doing squats, eventually reaching 100 BPM. Even if she looks fine, her heart is honest.
Even after her heartbeat calmed down, each beat was stronger than when she was doing squats, and her heartbeat told her that her valves were still opening and closing vigorously. When I put my hand on her chest, she said, "It feels like it's really moving!"
After taking some deep breaths, he seemed to calm down a little, and when we finally asked him to sit on the bed and rest, he said, "I feel even more relaxed."

When measuring various blood pressures and heart sounds, we first measure blood pressure while you are lying down and resting.
I thought his blood pressure would be healthy since he exercises, but I was shocked to see that it was extremely low.
My upper blood pressure is below 90 and my lower blood pressure is below 60. This is clearly low blood pressure.
When you compare your own blood pressure with the average for women, you might think, "It seems a little low!" as if it were someone else's problem.
Usually, people with low blood pressure find it difficult to get up in the morning, but Riko doesn't have that problem and doesn't suffer from anemia, so maybe she's an alien.
I had my blood pressure measured while sitting and standing. Of course, my blood pressure was higher than when I measured it lying down, but it was still classified as low.

The echocardiogram and heart sounds were exciting even before the scan, as it was the first time he had seen his own heart.
I feel like my heart is beating a little faster.
When the probe was placed on Riko's seated heart, which was about the size of her fist, it beat steadily, one beat at a time, and the heart sounds perfectly matched the movement of the heart displayed on the ultrasound screen. It was a beautiful heart shape, and she was surprised, saying, "What? A heart? It's shaped like a heart!" Afterwards, she looked at her own heart and repeatedly said how cute it was, reacting as if she were looking at a puppy.
When you hold your breath, your heart beat slows down accordingly.
When I placed the probe while lying down, I could see that the heart moved more slowly than when I was sitting, and this was also clearly visible.
Even when you're lying down, your heart is still beating hard without resting.

We've seen plenty of slow heartbeats under normal circumstances, so we'd like to see the fast heartbeat after exercise, right?
Of course, I wanted to see it too, so I had him climb up and down the step ladder.
The footage of him climbing up and down the step is shown in other footage, so that part has been omitted, and the footage starts shortly before the end.
When I put the probe on her right after she finished, I could feel her heart's rhythm becoming faster than before, and it was clear that her heart was working hard to send blood to her body just after exercise.
Riko also seemed surprised, saying, "That's fast..."
I had him take a deep breath and watched as his heartbeat gradually calmed down.
Toriko also said, "I feel like things have slowed down."
All of the ultrasound footage has been made into a separate video this time as well, so we hope you will take a look at that as well.

To hear the heartbeat while exercising while breathing through a bag, we put a bag over our head and airtightly seal it while we do leg-raising exercises.
I was also given a pulse oximeter, which is a little hard to see, but it displays oxygen saturation on the left and heart rate on the right.
Initially, the oxygen saturation level was around 92, but as the bag remained sealed and the patient continued to exercise, more oxygen was being consumed, and the patient was breathing deeply to ensure that oxygen was distributed throughout the lungs, which further reduced the amount of oxygen in the bag, dropping to as low as 68. Once, due to the patient's discomfort, the bag was loosened and the oxygen saturation level recovered slightly, but as soon as the bag was sealed again, the oxygen saturation level dropped again due to a lack of oxygen.
As the oxygen saturation level drops, the slow heartbeat also speeds up, reaching around 91 BPM. When the oxygen saturation level drops below 70, the heartbeat suddenly becomes stronger, "buck, buck, buck," and it is clear that there is a lack of oxygen.
Even though her body is exposed to the outside air, Riko is uncomfortable just because her head is sealed off, so she can only get oxygen through her nose or mouth.
Finally, the bag was removed and the patient was allowed to rest, and the oxygen levels returned to normal, and his heartbeat became slow as usual.

The sound of the heart when the chest was massaged was recorded by massaging the chest and recording the reaction and heart sound.
It is said that her bust has grown again recently, and is now an F cup.
She's petite and slim, but has huge breasts, which is unfair.
Her breasts felt soft and pleasant when I massaged them, and were very satisfying to massage.
While I was being massaged, she closed her eyes, looked like she was enjoying it, and at times she even let out a cry. Her heart was beating slowly, probably because she was relaxed.

Finally, I recorded the sound of Riko's heart beating when she used a vibrator on me.
She says she does it alone almost every day, and not only is she sexy and cute, but she also loves naughty things.
Riko, who is said to be very sensitive, was given a vibrator and when we turned it on she was initially surprised by its strength, which was very cute.
When she applies it to her private parts, she forgets about the camera and moans in pleasure. Her breathing gradually becomes rougher and her heartbeat quickens, and she reaches orgasm with her hips raised and her body trembling.
My heart was beating the fastest at that moment, and even after I reached orgasm, my body continued to twitch occasionally, as I was immersed in the afterglow of pleasure.
Not only was she sexy and cute, but the way she was doing it was also really erotic and made my heart race.
