Rin'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 the first heartbeat of 25-year-old Rin.
This is Rin, who has a cute face and short black hair that suits her very well.
As you can see from the sample images, it exudes cuteness.
She has a small face and big pupils, so I guess this is what they call a baby face.
Combined with her hairstyle, she looks even younger.
Her innocent smile is as cute as an angel.
She was petite at 152cm and 42kg, with small breasts, making her the ideal figure for a heart fetish model.
When we talked, she seemed like a very quiet person, and out of all the people we photographed, she had a similar vibe to Umi.

The contents of the video are:
・Self-introduction and heartbeat
・Feelings when listening to the heartbeat and the heartbeat
- The sound of your heart when you squat
- Heartbeat after stepping up and down
Heartbeat when chest is compressed
Echocardiogram and heart sounds
- Echocardiogram and heart sounds when standing
・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 something naughty
It is as follows.
The video is 57 minutes and 41 seconds long.

After Rin introduced herself, we put a stethoscope on her and could hear her heart beating at about 72 BPM. Rin herself seemed nervous.
He also answered questions such as, "Did you know about heart fetishes?" and "If your boyfriend had a heart fetish, would you want to let him hear your heartbeat?" and my heart started beating faster as he answered.

In the video about her thoughts when she hears the heartbeat and the heartbeat, when she first tries to put the stethoscope on, she realizes she's not wearing earphones, and it's cute to see her panic a little.
When we asked them to put on earphones and listen to their own heartbeat, the first thing they said was, "It's faster than I thought!"
When the doctor touched his carotid artery and listened to his heartbeat, he seemed to enjoy it and said, "It's the same rhythm!"
Next, we will place the stethoscope wherever you like.
When it is placed around the carotid artery or apex of the heart, the way the sound is heard changes, and he says it's ``interesting!''
Next, we asked them to take a deep breath and listen to the changes in their heart sounds.
While I was taking a deep breath, my heartbeat was getting faster and Rin seemed to notice.
Finally, when he drank some water, his heartbeat began to speed up again, which made Rin burst out laughing when she heard it, saying, "It's gotten so much faster!" She also said, "I wonder why? That's funny!"

Next, we asked Rin, who doesn't usually exercise, to do some squats.
He hadn't exercised much and didn't know what squats were, so I taught him and he managed to do them for two minutes.
Since he doesn't usually exercise, just a little bit of exercise makes his heart beat faster, and he laughed at the sound of his own heart, saying, "It's getting really fast!"
By the way, we also use a stethoscope while you are doing squats, so we can hear your heartbeat gradually getting faster.
By the end of the two minutes, your heart rate has risen to nearly 112 BPM, which is much faster than normal.
You can imagine Rin's heart beating hard inside her small body.
"It's beating like crazy," he said, slightly out of breath.
Taking a deep breath instantly slows down your heartbeat, which Rin describes cutely as "a sort of quiet feeling." Rin is putting her body on the line to prove just how effective deep breathing after exercise is.

We also listen to the heartbeat of the patient while they step up and down the step using a stethoscope.
As Rin said, my heart rate has suddenly increased when I do squats, but it feels like my heart rate is gradually increasing when I step up and down.
However, my heart rate peaked at around 124 BPM, which was faster than when I did squats, and I could tell that this exercise put more strain on my heart.
"Right now is the most exciting time for me," Rin said, and when I put my hand to my chest, I could feel my heart beating so hard it felt like it might burst.
Finally, please take a deep breath.

When we press on Rin's chest, we don't hold back on the sound of her heartbeat, even though she has a delicate body, just like we do with the other models.
He twisted his face in pain several times, and even right after the pressure was applied there were red marks, so I think it must have been quite painful.
The sound of Rin's heart also became louder and stronger during the compressions, and you could see from the video that my hands were twitching in time with Rin's heartbeat.

With the echocardiogram and heart sounds, the echocardiogram clearly shows Rin's heart inside her small body beating one beat at a time to send blood around her body.
(The black mass in the sample image is the heart. In the video, you can see it moving back and forth.)
Rin has a heart just like us, and it is proof that she is alive by beating it as hard as she can.
Seeing her own heart for the first time, she said, "Wow, it's really beating!" and also, "It's starting to look cute." When we asked her what shape her heart was outside of filming, she said, "It looked like a peach!", again using a cute description.
If you hold your breath during the test, you will also be able to hear your heartbeat speed up.
This time, I had Rin wear earphones and tried the ultrasound again. When I asked her to stretch during the test, I noticed that her heartbeat became a little faster.
"The movements and sounds have gotten faster," said Rin, as she opened and closed her hands in time with the movement of her heart.
Next, we performed an echocardiogram while the patient was standing.
It's easier to see your heart rate than when you're sitting down.
When we had them jump along the way, their hearts started beating faster.
At the end of the ultrasound video, the patient is asked to step up and down a step stool while the probe is placed on his pounding heart.
The ultrasound image shows the baby's tiny heart beating quickly and vigorously to send oxygen. Rin also said, "It's beating very hard."
After a while, things started to calm down and things started to slow down.

To measure the heart rate when exercising with the bag over one's head, participants lie down on their bed as usual, put the bag over their head and seal it shut, and then perform exercises such as pedaling a bicycle.
Whenever I explain the contents of the shoot, everyone seems to think it won't be too difficult at first, but when they actually do it, they tell me it's the hardest part.
The same goes for Rin. At first she is exercising while breathing normally, but you can see from her expression that it is gradually becoming more difficult.
Also, when he breathes, the bag sticks to his nose, making it even more difficult to breathe, and in the latter half he is breathing with his mouth open and panting, looking quite uncomfortable.
To prevent any accidents, we loosen the bags midway through the process, but then immediately reseal them to keep the oxygen levels inside the bags as low as possible.
Thanks to this, the oxygen saturation level on the pulse oximeter had dropped to nearly 74.
My heart rate has risen to 130 BPM, beating so hard I feel like my heart might explode.
By the way, the top of the screen shows your oxygen saturation level, and the bottom shows your heart rate. At the beginning of the video, the measurement doesn't work properly and an error message appears, but the numbers will appear soon, so don't worry.
Rin's breath had left droplets of water on the bag, so we took a photo of those at the end.

At the end, we had Rin do some naughty things and listened to her heartbeat. Rin seems to be a sensitive person, and she reaches orgasm three times in the video.
As a result, this video alone is quite long at just under 9 minutes, but that makes it highly recommended.
It's like a dream come true that such a ****like girl is about to engage in naughty acts and I get to hear her heartbeat as she does so.
First, she answered questions that she normally wouldn't ask anyone, such as "How many times a week do you have sex?", and then she applied the vibrator to herself. From the moment it was applied, she already seemed to be enjoying it, occasionally twitching and letting out small noises. At this point, her heart was already beating faster.
The moment she reaches climax is easy to see, as she says, "Ah... I'm coming."
Her face at that moment was also very erotic, and just when I thought she was just cute, it was unfair that she could make such an erotic face.
His heart is beating fast like a bell, thud, thud, thud, thud, thud, and he must be feeling really good.
After reaching orgasm again, the strength of the electric massager is changed and it continues to be applied again, and she reaches orgasm again. When she reaches orgasm, it is even more intense than before.
This was already a great reward, but the vibrator continued to be applied to her, and she finally reached climax once more. This time, her body twitched and convulsed as she reached orgasm, and she looked very pleased.
Even after it was over, I was still breathing heavily and basking in the afterglow of the pleasure.
At the end, when I asked him if it felt good, he replied, "It felt even better when I thought that you were listening to my heartbeat (blushes)," revealing his masochistic nature, saying that he felt it when I was listening to his heartbeat.
I am so grateful to Rin for allowing me to hear her heartbeat during the act, something that no one else can see.
