This is video 2 of Riko's heartbeat, 30 years old.
She's petite, standing at 153cm tall and weighing 43kg, and regularly works out at the gym and Pilates, resulting in a slim, toned body. Her blonde bob haircut gives her a gal-like vibe, and her sexy, cute appearance is striking, but she says she's actually quite laid-back, with a gentle way of speaking and polite language that makes the contrast with her appearance even more appealing.
Also, the sound of her heart beats is similar to Moriko's, slow and calming to listen to.
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.
In this video
Heartbeat when standing
Changes in heart sounds when sitting and standing
- Heartbeat when you hold your breath
Carotid artery pulsation and heart sounds
- The sound of your heart when you inflate a balloon after exercise
- Heart sounds when breathing through a bag
- Heartbeat when an electric massager is applied
It is as follows.
The video is 36 minutes and 27 seconds long.
First, when standing, the heart rate was about 76 BPM, which was slightly faster than when sitting.
Just changing your posture can change the rate at which your heart beats.
Next, we asked Riko about the difference in heartbeat speed when standing and when sitting.
First, we asked the patient to stand up from a sitting position. When the patient was sitting, his heartbeat was slow, but after he stood up, his heartbeat gradually became faster.
It's amazing how the heart can change the amount of blood it pumps out depending on your actions.
Riko was also surprised by the sound of her own heartbeat getting faster, saying, "I feel like it's gotten a little faster!" "Oh, it's getting faster!" "It's really fast!"
When I jumped, it was a little faster again.
The moment he sat down again, his heartbeat slowed down considerably, which was very easy to notice.
Next, we asked the patient to stand with the pulse oximeter attached and observed the change in heart rate, which was about 15 beats higher than when he was sitting.
When you look at the numbers like this, it's easy to see how much of a difference there is.
We will have you do the same jumps and then sit down at the end to monitor your heart rate.
The first time, the patient was asked to hold their breath for a short time, and the oxygen saturation level dropped slightly. The second time, the patient was asked to hold their breath for a little longer, for one minute, and the oxygen saturation level dropped to 92.
Finally, if you hold your breath again, you can see that the oxygen saturation level has dropped to 92.
When you hear the carotid artery pulsating and the sound of your heart, the area around the base of your neck twitches in sync with the heartbeat.
I took the photo from a slightly distant angle, but you can still see it moving clearly, exposing its vulnerable weak spot.
Even the gentle Riko would probably suffer and quickly faint if this area was squeezed tightly.
To measure the heartbeat when inflating a balloon after exercise, participants were asked to perform full-power step-ups for two minutes before inflating the balloon.
In this case, we will use a stethoscope on you even while you are climbing up and down the step stool.
After he finishes stepping up and down the stairs, his heartbeat is clearly faster, "dok dok dok dok," and he is given a balloon to inflate, but he is out of breath and in pain as he has to blow into it intermittently, so it doesn't inflate easily and his heartbeat is getting stronger. It's fascinating to see him trying so hard to suppress the urge to take a deep breath and calm his heartbeat right after exercise.
He managed to get a little air in, but it seemed he couldn't hold his breath, so he took a breath and inflated it again, and finally it was about the size of Riko's face.
He was still a little out of breath, so we gave him another balloon to try, this time one that was difficult to inflate.
To hear the heartbeat during bag breathing, a large bag was placed over the patient's head and the patient continued breathing while it was sealed. At first, the patient had some breathing room, but as the oxygen in the bag gradually decreased and the carbon dioxide increased, the patient's breathing became deeper and more intense. As oxygen deprivation gradually progressed, the bag was temporarily loosened and then resealed, and with safety as the top priority, the patient was pushed to their limits, and their oxygen saturation dropped from an initial 94 to 74. The powerful beating of the heart as it desperately tried to send oxygen could be heard through the stethoscope.
Riko loves naughty things so much that she does it alone almost every day. We put the electric massager on various parts of her body, and you can hear the changes in her heartbeat. This video is shot in a subjective style.
First, I put it on her topless chest. Her breasts seem to be sensitive, and she makes noises when I touch them, and when I touch her nipples, she flinches.
From there I move it to her stomach, and then to her lower body, where it seems to feel the best, and she moans in a sweet, cute voice.
Her voice gradually gets louder and she raises and shakes her hips, which is very intense and erotic.
It was so intense that at one point the stethoscope slipped off as she moved, and at the end she climaxed with her body twitching and convulsing, and her heartbeat was the fastest it had ever been.
It was very erotic to see her out of breath for a while right after she reached orgasm, basking in the afterglow of pleasure.
