Thank you for viewing.
This is a compilation of previously released videos of the model's heartbeat while she does leg raises and breathes through a bag.
The heart sounds of all the models during the bag breathing and exercise, which puts them under high stress, are very fast and rough, making this a work for people who like the sound of a fast heartbeat.
I always look forward to this shoot, and I could watch the footage again and again, seeing the models working hard exercising in the low-oxygen environment and their pounding heartbeats.
If many people purchase this, we'd like to continue it as a series.
The models appearing are:
・Everyone is 20 years old
Yumi, 23 years old
Mai, 23 years old
Sara, 25 years old
Rin-san, 25 years old
Umi, 26 years old
Sarami Kagamihara, 26 years old
Nagi-san, 23 years old
Risa, 28 years old
- Kanna Hiraizumi, in her 30s
Asuka, 25 years old
That is the case.
The video is 50 minutes and 2 seconds long.
Please note that the ages listed are those at the time of the photo shoot.
First person
These 20-year-old women have beautiful blonde hair that complements their fair skin, slim figures, and D-cup breasts—truly model-like physiques. They appear wearing masks, but their cuteness is still evident even through them. They lie on a bed, place a bag over their heads, and perform a cycling-like exercise for 2 minutes and 30 seconds while completely sealed. Breathing in a bag already reduces oxygen levels, and then exercising on top of that must be incredibly difficult. Several times, they loosened the bag due to the difficulty, but quickly resealed it to cut off oxygen supply as much as possible. As a result, the oxygen saturation on the pulse oximeter dropped to around 87 and their heart rate rose to around 122 BPM (sorry if it's hard to see). Their breathing became quite labored, and they were desperately trying to take in as much oxygen as possible. Even after the bag was removed, their breathing remained labored for a while, and we could see their oxygen saturation gradually increasing. It's quite poignant to realize that even young people like them need oxygen to survive. Finally, we also captured on video the condensation of everyone's exhaled breath that had formed inside the bag.
second person
Yumi, 23 years old, has a small face and is as cute as a doll.
Yumi also appeared wearing a mask, but her cuteness still shone through. She was also incredibly thin, to the point where I thought she might break.
About 30 seconds into the leg raises, she was already out of breath. She raised her hands a few times, so I loosened the bag slightly, but I quickly resealed it to prevent fresh air from entering. Towards the end, she was gasping for breath and breathing heavily, looking extremely distressed. Yet, all that was entering Yumi's lungs was stale air full of carbon dioxide, which was confirmed by the oxygen saturation reading on the pulse oximeter, which had dropped to around 79. Her heart rate had skyrocketed to 120 BPM, and her heart was beating so fast I thought it might break. When I removed the bag, she breathed ravenously, ventilating her lungs with fresh air.
third person
Mai, 23 years old, has a youthful face, and not only is she cute even without makeup, but her smile, especially when she laughs, is angelic. She is also slender, standing at 152 cm tall and weighing 43 kg. Mai worked very hard on the leg raises, and once she raised her arms, so we loosened the bag, but quickly resealed it and had her continue exercising. Her heartbeat, which had been slow, gradually quickened. Towards the end, she appeared to be hyperventilating, and we removed the bag. Her oxygen saturation at that time was recorded at 63, which is an extremely **** number. She remained in a daze for a while after the bag was removed. Finally, we showed the bag and could see a thin layer of water droplets that had formed due to her heavy breathing.
fourth person
Sara, 25 years old, is a beautiful woman with a small, well-proportioned face, striking black hair, and a slender figure—perfect in every way. She is sure to captivate every man in the world. I heard she is half-Japanese, which explains why she is so pretty. When she put a bag over her head and did leg raises, the bag inflated and deflated with her breathing, showing that it was tightly sealed. There were times when she loosened the bag due to discomfort, but even then, the air inside the bag did not seem to be completely ventilated, and she was constantly exercising while breathing oxygen-poor air. From her heartbeat, you could hear that her heart was beating hard to send the oxygen-poor blood throughout her body. At the end, she looked quite distressed and in pain. Her pulse oximeter reading dropped to 77 at one point, indicating that Sara's body was suffering from oxygen deficiency. It's no wonder she was in pain when her oxygen saturation dropped that low. When the bag was removed, she was breathing heavily, taking in fresh air into her lungs.
"I almost lost consciousness," was his final comment.
fifth person
Rin, 25 years old, has a cute, youthful face and short black hair that suits her perfectly.
She has a small face and large dark eyes; I suppose that's what you'd call a baby face.
At first, she is exercising while breathing normally, but you can see from her expression that she is gradually becoming more and more distressed. Also, when she breathes, the bag sticks to her nose, making it even more difficult to breathe, and in the latter half, she is breathing with her mouth open and gasping, looking quite distressed. The pulse oximeter does not measure properly at the beginning of the video and shows an error, but the values are displayed soon after, so please do not worry. Her oxygen saturation level dropped to nearly 74 at its lowest point. Her heart rate also rose to 130 BPM, and her heart is beating so fast that it looks like it might burst. There were water droplets of Rin's exhaled breath on the bag, so we filmed that at the end.
sixth person
Umi is 26 years old, extremely slender, has a cute face, black bob hair, a refined look, and beautiful skin.
There aren't many people who look this good with black hair and a bob haircut, so the moment I saw her, I thought she must be a goddess. As she continued to exercise in an oxygen-deficient environment, her heart rate increased, and a rapid "thump, thump, thump" sound echoed. Although it wasn't visible to the eye, Umi's breathing rate and heartbeat indicated that the bag was filling with carbon dioxide and oxygen was becoming scarce. As her breathing became more ragged and she raised her hands more frequently, the speed and strength of her heartbeat became more pronounced, conveying the desperate efforts of her heart to deliver even a small amount of oxygen to Umi's body. The video also includes footage of Umi calming down after the bag was removed and breathing in fresh air, as well as the gradual decrease in her heart rate.
seventh person
This is Sarami Kagamihara, 26 years old, a former adult film actress. Although she has retired from being an adult film actress, she is actively participating in fetish-themed photoshoots, and we were fortunate enough to have her appear as a model. As expected of a former adult film actress, she has an incredible aura, and of course, her slender figure was perfect. At first, her heart rate was 77 BPM and her oxygen saturation was 98, which is perfectly normal. However, as she exercised while breathing limited oxygen inside the bag, her heart rate steadily increased, while her oxygen saturation steadily decreased. She loosened the bag because it was so difficult to breathe, but immediately sealed it again, so the discomfort continued. As her breathing became more labored, she tried to take in as much air as possible by taking deep breaths, but the bag stuck to her face, making it difficult to breathe properly, and she looked extremely distressed. Even so, her heart was beating hard to supply as much oxygen as possible to her body, and her heartbeat was extremely loud. Her oxygen saturation eventually reached 74, a value that should not be seen in healthy individuals. His heart rate was reported as a maximum of 112 BPM, but listening to his heartbeat, it sounded even higher, pounding so hard I thought it might burst. After the bag was removed, he took slow, deep breaths to allow oxygen to reach his entire lungs and calm his breathing and heart rate, and the readings returned to what they were before he started breathing in the bag.
eighth person
Nagi, 23 years old, is beautiful and youthful with her translucent skin, well-defined features, and slender figure. She has a cheerful personality and seemed to enjoy the photoshoot very much. She says she has never been told she has any heart problems during health checkups, but when listening to Nagi's heartbeat, it usually beats normally, but suddenly it becomes a strange beat where her pulse stumbles and slows down, "thump, thump, thump, thump," and this was also seen in this video. At first she is breathing normally, but gradually each breath becomes deeper as she tries to take in as much oxygen as possible. However, her shortness of breath does not improve, and the amount of carbon dioxide in the bag increases further, and after about a minute, she raises her hand to indicate that she is in distress. Instead of removing the bag from her head and letting her rest, the bag is loosened to allow some air in and then sealed again.
After that, she continued exercising while breathing through the bag, and when she reached her limit, we loosened the bag to let in some air and then sealed it again. Her heart rate was at its highest at about 125 BPM, and you could imagine her heart working desperately to send the little oxygen she had to her whole body. When we removed the bag and let her rest, she was breathing in fresh air, panting. When she took a deep breath, her fast heartbeat seemed to stumble and slowed down to a rhythmic beat.
ninth person
Risa, 28 years old, has black hair and a clean, innocent look, and at first glance, she seems like a quiet person, but she's actually very friendly. Risa also tried very hard, and to give you the results first, her oxygen saturation level dropped to 55, pushing her beyond the limits of human endurance. At first, of course, she was doing fine, but as the bag deflated and expanded with her breathing, the oxygen inside gradually decreased, causing her breathing to become more labored, and her heart rate also increased as she did leg raises, making her look like she was in pain. She raised her hands several times to indicate that she was in pain, but we didn't loosen the bag, wanting her to keep going as far as she could, pushing her beyond her limits. Risa's suffering at that time was extraordinary; she was breathing with incredible ****, "Haaah haaah haaah," and occasionally making sexy sounds like "Mmm," twisting her body to try and escape the pain. It was something I could watch forever. When we loosened the bag at the point where it seemed she had reached her limit, she breathed desperately, trying to take in as much oxygen as possible. However, we immediately sealed him up and had him push himself to his limits again, resulting in his heart rate rising to 125 BPM and his oxygen saturation reaching an unbelievable 55.
Finally, after removing the bag and allowing her to breathe plenty of fresh air, she looked exhausted once her breathing calmed down. The bag was covered in many water droplets from her breathing, a testament to Risa's efforts, so we filmed this separately.
tenth person
This is Kanna Hiraizumi, in her 30s, a friend of Sarami Kakamigahara, whom I introduced earlier. This model is also a former adult film actress who has appeared in many works and is a well-known figure among those in the know. Even though she has retired, she still has a beautiful, well-proportioned face, is tall and slender like a model, and has a slim, toned waist and outstanding proportions that make it hard to believe she is in her 30s. The term "cool beauty" suits her perfectly. Due to her appearance, she has appeared in many S&M films, and it seems that she often played the dominant role, but in this video, we can see Kanna struggling with bag breathing. Like the other models, she starts off breathing normally, but as she exercises, her breathing becomes more rapid, and proportionally, her oxygen intake decreases, and the oxygen saturation level on the pulse oximeter changes. Also, the bag is stuck to her face, which makes her look quite distressed. Several times during the video, the bag is loosened and air is exchanged to prevent her from blacking out, but at some point she reaches her limit and says, "I can't, I can't!" As soon as the bag was removed, she began breathing frantically, her oxygen saturation dropping to 89 and her heart rate rising to 118 BPM, a rapid "thump, thump, thump." Even after the bag was removed, her breathing remained ragged for a while, making conversation difficult. However, after a short time, she managed to say, "My heart hurts..." and "My head hurts," barely able to breathe. Moreover, her speech was slightly slurred. Seeing Kanna, who is usually the dominant one inflicting pain, being pushed to her limits was incredibly exciting.

Asuka, 25 years old, is undeniably adorable, and her looks are sure to captivate you. When I actually met her, she was so cute that she was practically glowing, and it really lifted my spirits. Not only is she cute, but she also has a great figure, being tall with slender arms and legs like a gazelle.
Immediately after starting, the heart rate was 81 BPM and oxygen saturation was 99, both normal values, but these gradually changed, and we could see that the oxygen inside the bag was slowly decreasing. We had told the patient to raise their hand if they felt uncomfortable, but they persevered to their limit without complaining of discomfort, which caused their heart rate to rise to 125 BPM, their heart to beat very strongly, and their oxygen saturation to drop below 50, finally falling to 40, at which point we removed the bag.
After a while, her oxygen saturation returned to normal, but at that time, we could hear her heartbeat making a "thump, thump, thump, thump, thump" sound, like premature contractions, several times. Asuka had a "Huh?" expression on her face and didn't seem to understand what was happening. When I asked her about it later, she said it was a strange feeling, like she had lost consciousness for a moment. Even a cute person like Asuka needs oxygen in their body all the time, and if they don't get enough, this is what happens.
