These are the heart sounds of Riko, 31 years old, and Sae, 32 years old.
Riko and Sae have appeared on our show before, but this time they will be appearing together. Riko is wearing the pink swimsuit and Sae is wearing the light blue swimsuit.
Riko is short and petite, and very beautiful. She has a somewhat "gyaru" (trendy, fashionable girl) look, but she speaks very gently and is very demure. Another notable feature of Riko is that her heartbeat is quite slow, to the point where I wondered if she might have bradycardia.
In contrast, Sae had a beautiful face, was visually stunning, and was a very gentle and cute person, almost like an angel.
During their previous appearance, an irregular heartbeat was detected, but it wasn't present this time. Perhaps the previous appearance was abnormal. However, their heart rate was still fast, at a level that could be called tachycardia, and perhaps because it was their first meeting, they seemed extremely nervous, and there were moments when their heart rate seemed even faster than last time.
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 1 hour, 9 minutes, and 50 seconds long.
First, we had Riko listen to Sae's heartbeat.
Before listening to the heartbeat with a stethoscope, we first ask patients to place their ears directly on their chest and listen. They are often surprised and excited, saying things like, "Wow! I can hear it so clearly!" or "It seems surprisingly fast!"
It seems that even Riko can hear that Sae's heartbeat is fast.
Furthermore, Sae-san was also embarrassed to have her heartbeat heard directly by someone she had just met, and that seems to have caused her heart to beat faster.
When asked to place their hand on their chest to feel their heartbeat, they seem to be able to feel it if they press firmly, and when they put their ear to their back, they say, "I can hear it really clearly!"
It seems that if you put your ear directly to the speaker, you can hear it clearly even from behind.
After that, I had them feel my carotid artery and wrist pulse, and also checked my heart rate with a pulse oximeter. My heart rate was over 100 BPM, so it was pounding. I could tell from my heart rate that I was extremely nervous even before I listened with a stethoscope.
Then, they used a stethoscope to listen to my heart sounds.
Of course, we can hear the sound from the stethoscope here as well.
From the moment it hit, I could hear a heartbeat exceeding 100 BPM, "thump, thump, thump, thump."
"Wow, I'm so nervous!" says Toriko. Not only is the heart rate increasing, but actually hearing the heartbeat makes it feel really exciting.
I'll have you listen to your own heartbeat by placing a stethoscope on your chest, and I'll notice it's much slower than Sae's; I think your heart rate is probably about half as fast.
Riko couldn't help but laugh at how slow her own heartbeat was, saying "Huh?" and placed the stethoscope on Sae's chest and then on her own chest to compare them again, but Riko's heartbeat was clearly slower.
After that, the doctor placed the stethoscope on various parts of Sae's body and asked where the sound was easiest to hear. When he placed it on her stomach, he could even hear her stomach rumbling, and she said, "It made a rumbling sound."
Riko also placed a stethoscope on my back and listened to my heart sounds when I held my breath, took a deep breath, and drank water.
Next, we had Sae listen to Riko's heartbeat.
When I first put my ear to her chest, she said, "It seems a little slow." I then had her put her hand on her chest, but she said she couldn't feel the movement of her heartbeat, perhaps because it was too slow. I suppose people with faster heartbeats like Sae's are more likely to feel their pulse.
She also felt the pulse in her carotid artery and wrist, and it seemed she could feel that they were beating, but of course the pulse was slow, and she laughed and said, "It's really slow!"
Sae asked Riko questions such as whether it's better to have your heartbeat heard or to listen to it, and they answered each other's questions, and they also had a little talk about heart fetishes.
Also, when we measured your heart rate with a pulse oximeter, it was around 64 BPM, which is average, but that's about 40 BPM lower than Sae's.
Even among women of the same age, heart rates can vary so much, so it really shows how different it is from person to person.
When you actually listen to your heart with a stethoscope, it sounds incredibly slow, like "thump, thump, thump," making you wonder if it's really 64 BPM. You mentioned you're a little nervous, so this slowness is definitely buggy.
When Sae herself listened to the sound of her own heartbeat, she said, "It's about three times different!" and if you only listened to the heartbeat, it seems like there would be that much of a difference.
Even when they held their breath, there wasn't much change, but when they drank something, they said, "I think I'm breathing a little faster now?"
I also had them take deep breaths and asked if there was a difference in the speed of their breathing when inhaling and exhaling.
Next, we had each person listen to the sound of their heartbeat after doing step-ups.
First, Sae-san is doing step-ups.
They also used a stethoscope while Sae was doing step-ups, and it seemed that her already fast heartbeat became even faster with the exercise. When Riko put her ear to Sae's chest after she finished, she said, "My ear was pressed against it!" and "It's incredibly fast!" She was surprised by how fast it was.
Even when listening with a stethoscope, you can hear the rapid beating, saying, "It's really pounding!" It seems Sae herself could feel her own heart beating even without hearing it.
We also asked them to hold their breath for as long as they could, but perhaps because they were quite out of breath after the exercise, they couldn't hold it for as long as they wanted and started breathing again almost immediately. That just goes to show how hard they worked during the exercise.
However, he tried to stop it several times, and from that point on, his heartbeat gradually began to calm down.
Finally, after she took a deep breath and listening to her heartbeat, which was becoming calmer, Toriko said, "It's calming down more and more."
Next, we had Riko do step-ups. Her heartbeat, which is normally slow, was much faster immediately after she finished step-ups, with a "thump, thump, thump" sound, and her pulse was quite strong, indicating that she was pumping blood vigorously.
After it was over, Sae put her ear to Riko's chest and said, "It's fast!" Then, after listening with a stethoscope, she said, "It's fast, but maybe it's slowed down a little." I wonder if Riko's heart recovers quickly too.
We asked Riko to hold her breath again, but like Sae, it seemed difficult for her to hold it for a long time, and she started breathing again almost immediately. Her heart rate was slow, but it seems that the lack of oxygen in her body after exercise was having an effect.
Finally, after she took a deep breath, her heartbeat returned to its normal, extremely slow rhythm, and upon closer inspection, Riko's heartbeat is indeed very slow. Sae also commented, "It's really slow!", and shook her head in time with Riko's heartbeat.
Next, we used an echocardiogram to allow Riko to examine Sae's heart.
When the probe was applied, Sae's rapidly beating heart was displayed on the screen, and Riko was excited, exclaiming, "Wow, amazing, so precious!"
It's not every day you get to see someone else's heart.
The movements themselves were rather fast, but the rhythm was consistent, and they said things like, "It's pumping properly!" They also checked my heart while I held my breath, and they clearly explained the changes in my heart's movement when I held my breath and when I started breathing again.
We also had the patient's heart examined with an ultrasound immediately after they performed the step-up exercise.
When the probe was applied, Sae's heart was beating so fast that it seemed like she was convulsing, and the doctor commented, "The range of motion is bigger than before!" and also said that it was easier to see than when she was at rest.
They also noticed that my heart rate slowed down when I held my breath, and said, "It's slowed down."
Next, we switched places and Sae took a look at Riko's heart.
When we placed the probe on Riko's chest, a slow, wobbly mass appeared on the screen, moving slowly in time with her heartbeat, "thump, thump, thump." This is Riko's heart. It might depend on how it's positioned, but it also seems larger than Sae's. The speed is completely different, so you can immediately tell whose heart it is just by looking at the ultrasound. As usual, I've included just the ultrasound image. I've also made it so you can compare the two ultrasound images side-by-side, so please take a look at the difference in their movement speeds.
Sae also seemed to recognize the heart right away, saying, "I can see it here!" and then, "Is it round?" as she demonstrated the shape of the heart with her hands.
When I asked them to hold their breath, they would say things like, "Has it slowed down a bit?" and when they resumed breathing, they would notice the position of their heart moving and say, "Oh, it's moving!" They seemed to enjoy watching it.
After the exercise, when the probe was placed on her heart, it was beating faster than before, and she gestured with her hands to show how it was moving! She also said it felt like it was "bouncing," and she moved her head in time with the heartbeat as she intently watched Riko's heart.
When Riko and Sae were lying down, we could hear their heartbeats: Riko's heartbeat was heard from the right side and Sae's heartbeat from the left side.
It almost feels like both of your chests are pressed directly against my ear.
I've said many times that Riko's heart rate is slow and Sae's is fast, but now that I hear them beating at the same time, their rates are completely different.
Riko's heartbeat takes about one beat while Sae's beats about two, so it's almost twice as fast. I can't help but wonder if Riko's heart is too slow or Sae's heart is too fast.
Finally, we had them listen to the sound of our heartbeats while we were both masturbating in full nudity.
They said they were embarrassed to be seen masturbating, so they try not to look at each other as much as possible, and they listen to their heartbeats through earphones.
First, Sae masturbates, and Riko listens to her heartbeat. As an adult toy is inserted, her heartbeat gradually quickens, and she occasionally lets out moans. Listening to the changing heartbeat, Riko says things like, "It's getting faster!" and also asks Sae, "Does it feel good?"
Just before reaching climax, my breathing became ragged, I trembled as I came, and my heart was beating incredibly fast because Riko could hear me.
Moreover, even after it was over, she continued masturbating, and just like last time, she surprisingly reached orgasm a second time.
The first burst of lightning-fast heartbeat continued, so it remained incredibly fast for almost the entire time, prompting Riko-san to comment, "It's really fast," and "It's been fast the whole time."
Even after it was over, my breathing was still rapid, almost like hyperventilation, and my heartbeat didn't calm down right away. It seems that having multiple orgasms in a row puts a lot of strain on the heart.
Next, Riko will masturbate while Sae listens to her heartbeat.
There were some parts where the heartbeat was difficult to hear, so we have adjusted the sound quality to make it as clear as possible. Please understand that there may still be some parts where it is difficult to hear.
As she began to masturbate, she moaned in a sexy voice and seemed to be enjoying it very much. She also said "it feels good," and from that point on, her heartbeat gradually started to quicken, and it seemed that Sae could also tell that it was getting faster.
It seems that even Nariko's slow heartbeat speeds up when she engages in the pleasurable act of masturbation. Because her heartbeat is slow, the change is easy to notice.
She came, moaning "Ah, mm, mm," and immediately after it was over, she was panting and her heart was beating faster than when she was masturbating. When Sae asked her if it felt good, she replied shyly, "I came."
You can really tell from the changes in his facial expression, breathing, and heartbeat that he's truly reached orgasm.
Riko has a slow heartbeat, while Sae has a fast one. Because they are two people with different appearances and personalities, the unique qualities of each of them stand out, making this a work that is worth comparing. I'm really glad I offered them this opportunity.
