When the treadmill was first invented, it actually appeared as a torture tool to punish criminals.

In 1818, an engineer in the UK invented a prison treadmill, where prisoners need to step on wheels to generate power, which is used to grind grains or pump water.

Most of the time, prisoners do useless work by stepping on the wheel, with the purpose of just punishing them.

Compared with common punishments such as whipping, wax dripping, enema, etc., prison treadmills do not seem to be torture, but because the whole process is extremely monotonous and boring, it is the most terrifying thing about treadmills.

Prisoners live in harsh sanitary environments and have long-term fatigue and malnutrition, which often leads to accidental casualties during running. It was not until 1898 that the British Prison Law defined treadmills as "extremely cruel" that prison treadmills left the stage of history.

It has entered thousands of households and allowed fitness enthusiasts to be voluntarily punished.

Since seeing Luther's treadmill in his bedroom, Dongni Haiyi has always wanted to go up and try it, at least she has to watch others run around.

"Boss, if you change your running shoes, if you don't have special sportswear, choose a pure cotton and breathable clothing!"

After changing outfits according to the advice of the personal trainer, Lu Se found that Dongni Haiyi was standing next to the treadmill, taking off her shirt and trousers in a few seconds, leaving only the sports bra and bodybuilding shorts inside.

I'm really impatient... because there is a treadmill in front of me, do you think this place is a gym?

Although I had seen Dongni Haiyi's khaki underwear combination last night (and at the school gym), I got close to it in a well-lit environment and the shocking power was completely different.

"Boss, why are you standing there? First do the dynamic preparation activities, and then go up and run a lap!"

The so-called "dynamic preparation activity" is compared with "static stretching", which is very similar to the type of broadcast gymnastics, and is considered a scientific preparation activity.

Lu Se, wearing a cotton T-shirt and the same shorts, stepped on the treadmill, held the handle with both hands, slid one foot for a while to get used to the speed, and then ran.

"Yes! Don't be afraid! You won't fall! You can take a bigger step! Keep the rhythm, rhythm!"

Dongni Haiyi doesn't express her opinions casually in areas she is not familiar with, but once it involves sports, she will be very strong. Lu Se wants to take a break several times, but she stops him.

"It's only 15 minutes! Boss, are you still a man like this? Persevere, persevere! There is only one kind of failure, that is to give up halfway!"

I don’t know where Dongni Haiyi’s inspirational motto came from. Lu Se believes that even if he persists in masturbating every day, he cannot become the Olympic champion in the fancy plane masturbation event.

However, Dongni Haiyi's tone was quite exciting. She was asked by a female classmate, "Are you a man?" and she had to keep running anyway.

“Huh~Huh~”

The gasping sound became heavier, but there was a feeling of sweating. Lu Se applied the back of his hand to apply the oily liquid that oozed out of the tip of his nose and continued to persevere.

"Okay! The posture is a little tilted to the right, adjust it! Persist again! It will take at least 30 minutes!"

In order not to be too embarrassed in front of the tomboy, Lu Se tried his best to keep his posture from deforming. When he finally got off the track, there was only an exhausted buzzing sound in his mind.

"Is this exercise every day...that is it enough?"

Put your hands on your knees and keep breathing.

"If you want to follow my words, you can run at least 45 minutes at a time."

Dongni Haiyi did not show off, but simply expressed the facts.

"I'll go up and run, boss, watch my posture from the side and behind to see if there is any improvement in your running posture."

When Lu Se put a towel on his neck to wipe his sweat, Dongni Haiyi had already run up.

"Hey? This shock absorption effect is good! It's a very high-end treadmill!"

Dongni Haiyi drove the machine to the highest gear in 2 minutes, and her long legs moved away accurately and cheerfully, running towards the sunset (or whatever) like the protagonist of the anime op.

There is a double bed, a computer desk in Lu Se's bedroom, and a treadmill, and there are not many places left.

Lu Se, who was observing Dongni Haiyi's running posture nearby, could not control his gaze.

From the side, there is an elastic jump wrapped in a sports bra. From the back, there is also a twisting and friction between the tight hips under the bodybuilding pants...

Lu Se heard that among women who like to run, 70% of them don’t like to wear weight under tight shorts because they will wear thighs and even cause bleeding during long-distance running.

Fitness experts like Tony Hayyi may also belong to the "not wearing" school. In this way, the changing shapes strapped by tights are confusing.

"Boss, don't just spend time resting, carefully observe my running posture!"

Dongni Haiyi ran for 15 minutes, without any deformation in her movements, and her breath of speech was extremely stable.

Lu Se said "um" and thought to himself that although he wanted to observe his posture, he was attracted by your shape in the end!

After all, the bedroom is not a gym, and the narrow space leads to poor ventilation. The sweat from Lu Se's previous running and Dongni Haiyi's running quickly changed the smell of the air.

Dongni Haiyi was used to the smell of sweat in the gym and didn't care, but Lu Se couldn't completely ignore it.

How to say it? Because it is not the male-smelling smell of sweat from a group of brothers, it is not annoying.

Although human exohormones have long been degraded and cannot be compared with insects at all, sweat can more or less play a role in exohormones.

On the black market of the "Chaos Club", Lu Se has seen someone asking for the smell of his butt after his girlfriend's fitness, and he also wants to buy "armery sweat" for $2,000.

It is definitely no second to Director Cao, and it is perverted in another dimension.

Thinking of this, the sweat-smelling space produced by Toni Hayyi running in the airtight bedroom can be rented out at about $1,000 per hour? Is it not that expensive for a month to rent out my house!

Lu Se, who felt dry mouth for various reasons, took two bottles of mineral water he had prepared from the computer desk, and handed it to Dongni Haiyi a bottle.

"Thank you! Then I'll stop for a while."

Dongni Haiyi took the mineral water and walked down from the treadmill.

After running for half an hour, Lu Se was exhausted and sweaty on his hands, he slipped the bottle cap for the first time and didn't unscrew it.

Dongni Haiyi smiled heartily, held Lu Se's bottle and twisted it from the side, and easily opened the mineral water.

"It will be easy to do this if you don't exercise for too long. Boss, you have to persevere in the future!"

Then I unscrewed my mineral water, turned my head back and took off to rehydrate it, leaving only the twelve-level intelligent creatures with self-esteem.

Although he was not arrogant enough to help Dongni Haiyi turn the bottle cap, this kind of work was originally a boy's obligation, right? This time it turned around!

"Hey? It's so late? Then let's get here today. I'll change my sneakers and don't break your floor..."

Dongni Haiyi bent down to Lu Se to change her shoes, hung her waist with fine sweat beads, and her perky buttocks with tempting arcs under her fitness pants were all hitting the nerves of boys of the same age.

I heard that Xiaojia has an angel cosplay costume from "Overwatch". "Overwatch" has a nickname called "Overwatch Ass" because she is too hard to portray the buttocks of female characters.

Why does the world exist? Lu Se thinks sometimes it is not necessarily a great reason.

Perhaps at some time and place, the so-called hero defeated the devil and saved the world, and the original purpose was to protect his girlfriend's butt.

It is absolutely impossible to let that kind of thing dominate the world without understanding the beautiful artificial intelligence of the butt!
