This is the second set of heart sounds from Riko, 31 years old, and Sae, 32 years old.
The one in the pink swimsuit is Riko, and the one in the light blue swimsuit is Sae.
Despite her short stature and petite build, Riko is a very beautiful woman. Although she has a somewhat gyaru-like, mischievous appearance, she speaks very gently and is quite demure. Another notable feature of Riko is that her heartbeat is quite slow, to the point where you might think she has bradycardia.
In contrast, Sae had a beautiful face, was visually stunning, and was a very gentle and cute person, almost like an angel.
Just like last time, their heart rate was fast enough to be called tachycardia, and perhaps because it was their first meeting, they seemed extremely nervous, and there were times when I thought their heart rate was even faster than last time.
In the first session, participants listened to each other's heart sounds, and here too, we had them listen to each other's heart sounds and also took electrocardiograms so they could see each other's electrocardiograms.
We asked two people who are completely different in appearance, personality, and heart rate to listen to each other's heartbeats during normal times, after exercise, and during masturbation, and also to examine their hearts using an ultrasound.

That is the case.
The video is 59 minutes and 30 seconds long.
First, we had each other listen to the sound of our heartbeats while we were standing.
First, Riko listens to Sae's heartbeat.
Before using a stethoscope, when the patient placed their ear directly on their chest, they exclaimed, "I can hear it!" They also mentioned that their heartbeat was stronger than when they were sitting, making it even easier to hear, and they used their hands to indicate the strength of their heartbeat.
Your heartbeat seems noticeably stronger than when you were sitting.
Even when you place your hand on your chest and try to feel your pulse, it seems to be easier to feel than when you were sitting. The fact that there's such a big difference between sitting and standing is probably partly because Sae's normal heartbeat is fast.
Furthermore, when we measured his heart rate with a pulse oximeter, it was 108 BPM, which was higher than when he was sitting, indicating even more tachycardia. He seemed to enjoy the real-time changes in his heart rate, exclaiming things like, "It's moving!" and "Oh, it's at 109!", and he watched the numbers for quite some time.
Although Riko didn't notice, a rumbling sound could be heard, which was Sae's stomach rumbling.
She was holding her stomach a little, and her heart rate went up slightly at that time, and Riko said, "Oh, it went up!" It seems her heart rate went up because she was embarrassed that her stomach was rumbling. How cute.
Then, using a stethoscope, they listened to my heart sounds.
The "thump, thump, thump" sound was so fast that anyone who heard it would think it was fast, and people commented, "Wow, you're so energetic!", "It's really thumping!", and "It's quite fast!", to which Sae looked a little embarrassed. It's understandable that she would be embarrassed if someone heard the sound of her own heart and told her what it sounded like.
If you squat down, the speed will slow down slightly and the strength of your heartbeat will also be weaker.
Riko also said, "I feel like I've slowed down!" and when she stood up again, her heart started beating very fast the moment she stood up, and she seemed happy, saying, "Wow, that's fast!"
Furthermore, by having the robot squat and stand up several times, it clearly demonstrated how the heartbeat changes depending on the posture.
Next, we had Sae listen to the sound of Riko's heartbeat as she stood there.
He put his ear to my chest and listened directly to my heartbeat, saying, "It's faster than before!" However, even though it was getting faster, he couldn't feel my heartbeat when he put his hand on my chest.
When I measured my heart rate with a pulse oximeter, it was 69 BPM, which is quite a bit higher than when I'm sitting.
Even so, if you put your hand on your chest, you can't feel your heartbeat. Is that because Riko's breasts are so big?
When we listened to the patient's heartbeat with a stethoscope, we found that while it was so slow when the patient was sitting that it seemed like it might stop, it was now at a normal speed, and the patient exclaimed, "It's much faster than before!"
I asked her to squat down once to listen to the changes in her heartbeat, but it didn't seem to change much, and Sae-san also said, "It doesn't seem to have changed much."
If you stand up again, it will be a little faster, but the range of speed variation is completely different compared to Sae's earlier video.
In Riko's case, one of her distinguishing features seems to be that there isn't much change even when she changes her posture, unlike Sae.
We asked her to squat down and stand up several more times to see if there was any change, but she said, "Nothing's changed..." and "It's the same!" while nodding her head in time with Riko's heartbeat.
Next, we had them listen to each other's heartbeats while they were doing squats.
While I was doing squats, they also used a stethoscope to listen to how my speed gradually increased.
First, we'll have Sae-san do some squats.
Sae did squats for two minutes, and while Riko was cheering her on with "Keep going!", she was listening to Sae's heartbeat and saying things like "It's getting a little faster!" and "It's getting even faster!", and after it was over she said that it had gotten faster in three stages.
Even after it was over, her heartbeat didn't subside; in fact, it got even faster, "thump-thump-thump-thump," with a heart rate of around 130 BPM, the same speed as a small ****. She was also out of breath, indicating that the two minutes of squats had been extremely hard on Sae. Her heartbeat, which was already fast before the squats, had become even faster.
Riko also said things like, "Oh, it's still fast!" and "My heart is beating stronger now!" When she put her hand on my chest, she could feel the pulse just by lightly touching it, and said, "It's beating fast!" which was a cute way of putting it. She also touched my carotid artery, and when she took a deep breath at the end, my heart started to calm down little by little, and she said, "It's calmed down a bit!"
Next, we reversed the roles: Riko did squats, and Sae listened to her heartbeat.
Riko's heartbeat, which was initially slow, gradually sped up as she did squats, and the change was easy to hear and notice.
Sae, who was listening, said things like, "Is it getting a little faster?" and "It's getting faster!", and even immediately after it finished, it was faster than before it started, and she said that she could feel her heartbeat when she put her hand on her chest. It seems that not only is it getting faster, but the heartbeat itself is getting stronger.
However, Riko's heart recovered quickly and soon returned to its normal slow pace. Once she started taking deep breaths, it was completely slow again. She mentioned that she exercises regularly and goes to the gym, so that might be a contributing factor.
Next, we each had the opportunity to use an ultrasound probe to examine our hearts.
We also performed an echocardiogram for the patient with heart sound 1, but in that case, I was the one who placed the probe. Here, however, we each placed the probe on the other patient to locate the heart.
First, Riko is applying the probe to Sae.
Riko adjusts the position and angle of the probe, saying things like, "Is it like this?", and when she finds the heart, she happily exclaims, "Ah, I can see it!" The heart is moving quickly, so it's easy to find.
By shifting the position of the probe, the appearance of the heart changes accordingly, which proves that what is displayed on the screen is Sae's heart in real time.
Also, if you lower the probe slightly towards the abdomen, you can see small, round objects that are moving in time with the heartbeat. I think they are probably arteries or veins. They are moving well and pumping blood.
Riko also said things like, "What is it?" and "Is it food?", and carefully observed Sae's insides.
Next, Sae placed the probe on Riko and helped locate her heart.
I was worried about whether we could find it because its movement is slower than Sae's heart, but as soon as you applied the probe, we found a beating heart. The heartbeat is so slow it looks like it might stop, but the movement is easy to see. You're very skilled at applying the probe.
"I can see it so clearly!" said Sae-san, and she even pointed to her heart.
Just like with the first heartbeat, it looks larger compared to Sae's. Riko is shorter, so you might think her heart would be smaller, but that doesn't seem to be the case. The difference in size is noticeable because Sae doesn't exercise much, while Riko regularly exercises at the gym.
The probe was then placed on Sae-san and Riko-san's abdomen, and similarly, what appeared to be the aorta and veins were visible and moving well. The probe was then placed on their chests again, and upon seeing their hearts, the doctor exclaimed, "The hearts have a really strong presence!"
We also have ultrasound-only images, so please take a look not only at the heart but also at the aorta and veins.
Next, we used an electrocardiograph to look at each other's electrocardiograms.
First, we attached an electrocardiogram to Sae-san.
Once the electrodes are attached, the screen displays the electrocardiogram waveform and heart rate, which is around 85 BPM. Since I'm lying down, it's a bit on the fast side.
I also had Riko read out her current heart rate, and then she stretched so I could observe the change in her heart rate.
Next, we had them do leg raises so we could monitor the changes in their heart rate.
As Sae exercises along with the video I'm showing her, her heart rate increases, and Riko reacts to the changes in Sae's heart rate, saying things like, "It's going up and up!" and "Oh, it's over 90!"
After that, her heart rate continued to rise rapidly, and immediately after it was over, her heart was beating at over 100 BPM, and she looked quite distressed and out of breath. It seemed even harder for her than when she did the squats, and when Riko asked if it was tough, she said it was, as expected, and her heart rate spoke volumes about how tough it was.
We asked him to rest and let his heart rate calm down, and then we asked him to hold his breath.
We asked her to hold her breath for one minute, and we observed that her heart rate increased slightly at the beginning of the breath-holding period, then decreased, and her oxygen saturation level also decreased slightly. Riko also monitored her heart rate and pointed out the changes.
Since he seemed to be able to hold his breath for one minute without any problems, we also asked him to try holding his breath for two minutes.
Towards the end, the **** was flapping its legs and appeared to be in distress, and we were able to see its heart rate at the limit of oxygen deprivation.
Next, Riko had an electric massager applied to her by Sae, and we also looked at her electrocardiogram while she was experiencing the sensations.
For someone as shy as Sae, this situation is more than just embarrassing.
Even so, she's a truly wonderful model for going to such lengths for the photoshoot.
As Riko slowly begins to apply pressure, her body twitches, and she involuntarily lets out a soft "Mmm" as she feels the sensation.
Her heart rate is also changing little by little, and as she moves around, twisting her body, her heart rate is rising even more, and Riko says things like, "It's over 90!"
I wonder if the feeling of satisfaction is different when you guess correctly yourself compared to when someone else guesses correctly for you?
This time, I reached the limit twice in a row. The first time, my heart rate dropped below 100 BPM, but I quickly reached it again, exceeding 100 BPM the second time, and my heart rate remained elevated for a while afterward.
Judging from her high heart rate, it's clear she was really climaxing. And since it lasted for a long time, I think it must have felt incredibly good. The heartbeat I heard through the stethoscope was not just fast, but the pulsations themselves were strong, and she was breathing heavily.
As Riko removed the electric massager, her heart rate gradually decreased, but her breathing was still labored. We asked Riko to share her thoughts on the series of changes in her heart rate.
Next, we attached an electrocardiogram to Riko.
The last time I photographed Riko, we didn't have an electrocardiograph, so this will be her first time using one.
The video starts immediately after the electrocardiograph is attached.
The displayed heart rate is 57 BPM, which is below 60.
Because Sae's heart rate was high, it probably felt even slower.
If you stretch in the same way from there, your heart rate will increase and change.
Also, when she does leg raises, her heart rate rises to over 70 BPM, about the same as when she's at rest. It's especially nice to see it rise when her heart rate is low.
We asked him to hold his breath, but he couldn't hold it for a full minute. After about 30 seconds, he became distressed and started breathing again.
My heart rate did decrease while I was holding my breath, so it seems that holding my breath had some effect.
Finally, when Sae applied the electric massager to Riko, Riko let out a moan and her heart rate began to change. Sae was captivated by the fluctuating heart rate, and she accidentally shifted the position of the massager midway through. Noticing this, Sae applied it to Riko's sensitive spots again, and Riko flinched as if caught off guard, and her heart rate also increased.
Unlike masturbation, this reaction is unique because it's something that can't be controlled.
He reached his peak at the very end, and that was the moment he was at his highest.
In the prank game, Riko and Sae played the game "Blackbeard's Treasure," and you can hear Riko's heartbeat from the left and Sae's from the right.
It may be difficult to hear both simultaneously, so we recommend listening to one at a time in two separate sessions. Also, please note that there are parts where Riko's heartbeat is difficult to hear.
They tried it twice, and one of them was thrown off both times, so as a penalty, they had to use an electric shock pen. You'll have to watch the main video to find out who got the penalty.
I think this video also fully showcased the unique personalities of both of them.
If you prefer a fast heartbeat, Sae's heartbeat might be better, and if you prefer a slow heartbeat, Riko's might be better. Of course, both models are wonderful, and if you like heartbeats, I highly recommend listening to both.
The format is "MP4".
