Thank you for viewing.
This is the second set of heart sounds from Riona (23 years old) and Himari (22 years old).
Both models have appeared in our videos before, and we were happy to have them participate again.
Riona is a beautiful model with a bright personality and a large bust. It had been about six months since her last appearance, but she had become even more beautiful than when we last met, her beauty had been further refined.
Himari is a petite, cute, and fluffy-looking model with a small, ****-like appearance. If Riona is the beautiful type, Himari is the cute type. She's an incredibly cute model who is soothing just to look at.
The girl in the pink swimsuit is Riona, and the girl in the light blue swimsuit is Himari.
In the second session, we included video footage from an electrocardiogram, allowing us to not only hear the heart sounds but also observe the reactions of the two participants as they viewed the electrocardiogram waveform and heart rate.
This also showed how close the two of them are, and it was heartwarming to watch.

That is the case.
The video is 47 minutes and 17 seconds long.
First, we asked the two of them to listen to each other's heartbeats while they were standing.
Initially, Riona is listening to Himari's heartbeat. When she puts her ear directly to Himari's chest, she says, "It's beating faster than before!" Before this shoot, they filmed a segment where they listened to each other's heartbeats while sitting, so compared to that, Himari's heartbeat seems faster, and she also seems a little nervous.
When you place your hand on your chest, it seems you can feel the pulse more easily, and it's not just fast, but the pulse itself is strong. It must be really strong if even Riona can feel it when she places her hand on it.
If you place the stethoscope here and listen to the heart sounds, it seems that you can't hear anything at first due to the earphone connection, but after a while, Riona can hear it, and listening to the heart sounds, it is faster when she is standing, with a heart rate of about 76 BPM.
Then I asked Himari to squat down on the spot.
"It's gotten slower!" she was told, but when she stood up again, Riona noticed that it had actually gotten faster.
Next, we asked them to jump in place, which seemed to have improved slightly. Finally, we asked them to do an air squat for one minute. Even before they started, they were already jumping faster, suggesting that they were getting more nervous and therefore faster.
My heart rate slowed down a bit because I had squatted down to do the air squat, but it gradually sped up again, probably because I was in a difficult position for an extended period. By the time I finished, I think it was almost twice as fast as it was at the beginning.
Next, Himari is listening to Riona's heartbeat.
Similarly, when they put their ear to their chest and listened directly, they said it wasn't much different from when they were sitting. When they put their hand on their chest, they said they could feel the heartbeat resonating! The speed didn't seem to change that much, but perhaps because they were standing, the pulse of each beat was stronger, so they could feel the heartbeat more clearly when they put their hand on their chest than when they were sitting.
When they listened to her heart with a stethoscope, they heard a "thump, thump, thump" sound, and the beat was stronger than when she was sitting down. Himari also commented on what she thought, saying that the beat was faster than usual.
We asked Himari to squat down and then stand up again, and we listened to her heartbeat. It was fun for us to watch as Himari reacted, saying things like, "Oh, it's slower now!", "It's a little faster now!", and "Huh? It's not that different?", and it made Riona laugh.
After having them do the jump a few times in place, they seemed to notice that they were indeed faster at this point.
Finally, we also let them hear Riona's heartbeat while she was doing an air squat.
While saying "Wow," they listened to Riona's heartbeat, which sounded strained, and commented, "Oh, it's fast!" It seemed they had noticed the change as well.
Next, we asked them to listen to each other's heartbeats while doing squats.
First, Himari is doing squats.
The air squat exercise we did earlier was for one minute, but this one will be for two minutes.
Himari's squats are done in a style where she lowers her hips as far as possible, and her heart rate is already increasing after about 10 seconds.
"It's getting really fast!" "It's too fast!" Torio-san said, and she nodded her head in time with Himari-san's heartbeat.
As Riona mentioned, Himari's heartbeat is incredibly fast, and right after it ends, her heart rate is around 120 BPM, which is slower than when she did step aerobics, but even so, the sound of her heartbeat is so loud that you might think it's going to explode.
Immediately after it was over, Himari was out of breath, and although she had calmed down a bit, her heart was still beating quite fast. When Riona listened to it and touched her carotid artery, she said, "It's fast! About as fast as this sound!"
Finally, I make sure to include a deep breath to help you calm down.
Next, we have Riona doing squats.
It was a little slower than when Himari was doing it, but her heartbeat was still gradually getting faster, and Himari, who was listening, said things like, "It's getting faster and faster!" Immediately after it was over, it had risen to about 110 BPM, and when we touched her carotid artery, she was surprised by the difference from when we touched it normally, saying, "Wow! It's beating so fast!" Her reaction was adorable. Finally, we had her take a deep breath to calm her down.
Next, we used an electrocardiograph to look at each other's electrocardiograms.
It's a rare experience to see someone else's electrocardiogram.
First, Riona is looking at Himari's electrocardiogram.
When Riona attached the electrodes, Himari's electrocardiogram waveform was displayed on the screen, and the heart rate, which was displayed at the same time, fluctuated between 55 and 58 BPM, which is lower than the average heart rate.
It's probably lower because you're lying down.
Riona, who was watching, also commented that the tempo was quite low. It briefly rose to 62 BPM but then quickly dropped again, and she seemed to enjoy watching it, saying, "Oh, it's going up!"
I asked them to keep their legs raised from that position for one minute.
The heart rate increases the moment you raise your hand, and the waveform becomes distorted at that time. However, it's clear from the sound of your heartbeat that it's getting faster.
Even after the session ended and I was able to put my legs down, my heart rate didn't immediately settle down and was still quite fast. I was surprised at how much of a difference simply lifting my legs could make.
Riona also monitored the changes in her heart rate during that time and shared the changes with us.
Next, we asked you to hold your breath.
When Riona gave the signal to hold her breath, it initially dropped to around 54 BPM, but then gradually increased. When she resumed breathing because it became difficult to breathe, it jumped straight to over 70 BPM, prompting Riona to exclaim, "It's going up!"
Finally, we had Riona try out the electric massager. Of course, she was wearing an electrocardiogram throughout, so we could see her heart rate at every moment she felt pleasure. It was exciting for those watching, but I wonder if it was incredibly embarrassing for Himari?
When Riona applies the electric massager to Himari's genitals, she makes sounds of pleasure, and you can see that her heart rate increases as she applies it. Himari asks Riona where it feels good as she applies it, and she keeps an eye on Riona's heart rate, saying things like, "Is it going up a little?"
Midway through, Himari applied the electric massager to herself, which caused her heart rate to rise even further. She said, "Oh, I'm about to come," and "Oh, I'm coming," and she did indeed reach orgasm. At the moment of orgasm, her heart rate rose to 75 BPM, about the same speed as when she lifts her legs. After it was over, Riona shared her thoughts on the changes in her heart rate.
Next, Himari took a look at Riona's electrocardiogram.
Incidentally, the last time I photographed Riona, I didn't use an electrocardiograph, so this will be her first electrocardiogram.
Here too, Himari attached electrodes to Riona, and once attached, the displayed heart rate was around 56 BPM, which is on the lower side for Riona as well. In Riona's case, her heart rate is naturally on the slower side, so this is not surprising.
As the two of them were talking and comparing the heart rate readings on the electrocardiograph with their average heart rate, their heart rates increased slightly and exceeded 60 BPM.
When Riona did the leg raises, her heart rate rose steadily, reaching a maximum of 90 BPM at one point, which was a larger increase than when Himari did it.
When you hold your breath, your heart rate drops sharply at first, indicating a diving reflex.
Also, the time it was stopped was longer than when Himari-san was there, and Himari-san was surprised, saying, "Wow! That's quite long!"
However, it was impossible to hold his breath indefinitely, and he eventually became distressed and resumed breathing, at which point his oxygen saturation level had dropped to 85. This suggests that he had been holding his breath to the absolute limit.
Himari's reaction at that time was also one of surprise at how low the oxygen level had become.
Finally, we showed Himari the electrocardiogram taken when she used the electric massager.
When touched, they close their eyes and seem to enjoy it, and their heart rate gradually increases.
Himari said, "I think it's gone up a little?" as she watched his heart rate.
Midway through, when Riona herself started applying the pressure, the sensations increased even further. It seems that when she applies the pressure herself, she can better understand the intensity and the spots that feel good, making it easier to feel the sensations.
Just as it was about to reach its peak, the BPM exceeded 100, and the oxygen saturation level also dropped, so much so that Himari exclaimed, "Wow, that's amazing!"
It came very close to reaching its target, but it didn't quite make it, and the heart rate dropped back down to 60 BPM. Just like with the leg raises earlier, the increase is so large that it puts a lot of strain on the heart.
After a while, her heart rate started to rise again, and her expression suggested she was close to climaxing. She exclaimed, "Oh no! I'm coming!" and then she did. Her heart rate rose to 110 BPM at that point, which was even higher than before, and the change in her heart rate clearly showed that she had truly climaxed.
"It's gone up!" Himari said happily as she watched.
When Riona and Himari are lying down, the audio is adjusted so that Riona's heartbeat is heard from the right and Himari's heartbeat is heard from the left.
This is the first and last time we'll be able to hear the heartbeats of the beautiful Riona and the cute Himari at the same time.
Listening to them side-by-side like this, it's easy to hear that Himari's heartbeat is faster, while Riona's is slower.
It feels almost as if you're listening directly to her chest with your ear.
Although the two of them had differences in their personalities, heart rate, and how their hearts beat, it was precisely because of these differences that the work became something that was never boring to listen to, and their close relationship also shone through. I was reminded once again that offering them the opportunity was truly the right decision.
