Sua and Sia grew up in a very blessed environment from an early age.
Their mother's side of the family were very wealthy, so they lived their lives getting everything they needed or wanted from a young age.
It played a big role in creating their personalities.
Usually, raising a child by buying them all the things they want or asking them to come or not is avoided because the child becomes stubborn or selfish as he or she grows up.
It's a little different in the M world.
This was the preferred parenting method because it helps develop children's S tendencies and helps them live while suppressing their M tendencies.
People who cannot tolerate M tendencies often expose themselves or masturbate on the streets alone, are looked down on by others, and end up in jail.
It was very important to suppress the M tendency while increasing the S tendency even a little.
Among them, Sua and Sia were raised to overcome their M tendencies and played a big role in making them who they are today.
Moreover, they also have another characteristic, which was that they have a very strong tendency to be lesbians and incestuous.
From an early age, the two grew up as each other's lover, master and slave, and because of that, they never thought of receiving training from someone else.
They grew up with the optimal disposition to become a professional trainer who can easily suppress their desires when training others.
Therefore, although they have not yet obtained professional qualifications, it was certain that once they become professional assistant trainers, they will immediately become top-ranking assistant trainers.
These two have very outstanding abilities as training assistants.
The chairman knows well, so if he receives recognition from both of them for sending Taeyang to Sua and Sia
From the chairman's perspective, it was worth considering not only letters of recommendation but also investments.
From Taeyang's point of view, he must win at all costs, and Sua and Sia want to train Taeyang, so they plan to make him completely their slave.
From the perspective of people in the M world, there are very few people who can endure their training for more than an hour.
Usually, in less than 30 minutes, most people beg to become their slaves.
This time, when Taeyang agreed to the bet, they started training with the idea that he would become their slave.
The girls started betting with excitement, as if they had a new toy.
'Hmm… he doesn't look like much at first glance... Well, he's tall for a man. And his dick is big... no it's huge.'
Sua, who casually stepped on Taeyang's dick and took it out, pretended not to worry, but in fact she was surprised by Taeyang's big dick.
She hides the fact that her heart was beating fast with a cocky attitude.
'I think Sia was really surprised too.'
As twins, Sua and Sia know each other's feelings well, no matter how much they act.
Now, in Sua's eyes, she saw that Sia was as surprised as she was.
Since they usually only train women, this was their first time training men, but when preparing to become a training assistant, they also learned things about male and female training assistants.
Since they had to know everything and had learned it through sex education, they thought there would be no problem because they had the knowledge.
'I heard it's usually less than 10 cm, but this size is too big!'
They were taken aback by the fact that his size was incomparable to that of men in the normal M world, but now they were training Taeyang.
They can't show it on the outside and were stimulating Taeyang with their usual arrogant, S-like expression and tone of voice.
Seuuk
Tap, tap, tap, tap.
"Ugh!!"
"Hehe, does it feel good to have your dick grabbed by these little hands?❤"
"I thought you were a adult... But you're a pervert who likes Oppais girls❤"
"Oh, no!… Ugh… This is an unavoidable physiological phenomenon!"
"Lies~❤"
"Oppa, your dick is leaking such transparent fluid?❤"
The feel of the cock that she touched for the first time was hotter than Sua expected and she was a little nervous because it was too big for her small hands to hold at once.
'It's the same regardless of whether it's a woman or a man!'
It was a little awkward to be trained by twin girls and touch his cock for the first time, but Taeyang was feeling the pleasure they both give him at the same time.
Moreover, no matter how strong their mental power was, it is normal for the M-world's demonic humans to not be able to resist if they are repeatedly verbally criticized and stimulated.
That's why Sua thinks that Taeyang's resistance and rebellion now won't last long.
"I think you like my feet more than my hands."
"Then let's do it with our feet❤"
Seuuk
"Ugh! These little guys… Ugh!"
As expected, stimulation with just their hands wasn't enough, so they turned around, put their feet out on either side and massaged Taeyang's cock.
"What~ Are you feeling it right? After all, it's natural that you like our feet more than our hands❤… We'll make you our slave in no time."
The stimulation of the girls' hands was weak, but as the two who were good at using their feet stimulated Taeyang, he felt it even more and was leaking precum.
Although he was angry at the humiliating pleasure he has experienced for the first time in his life, Taeyang's body was feeling external stimulation that he cannot resist as a man.
'Still, he is holding up better than I thought? Normally, it only takes 10 minutes to howl like a dog in heat.'
The two of them are massaging Taeyang's dick with their feet and were surprised to see that Taeyang was holding up better than expected.
No matter how proud a woman is, if two people tease her by stepping on her pussy at the same time, she will feel like she has completely given up resistance after just 10 minutes.
Now, Taeyang has already been being bullied for 20 minutes, let alone ejaculating; his eyes are not getting any more impatient.
'If we do this... Sia'
'Yes… Sua'
Sua, who decided that it would be impossible to subdue Taeyang for the remaining time, exchanged glances with her and immediately changed her posture.
"Hold it well, Oppa❤ Then, I'll do it right this time, so get up."
"It feels so good that you can't cum right away like a pig in heat❤"
"Whew… See you in 40 minutes."
Flinch…
'What is this❤… This is my first time looking at eyes like this. Ah, Sia felt it too❤'
Despite being humiliated with his hands and feet for 20 minutes and being verbally criticized, Taeyang, unlike other M males, glared at them with an angry expression.
Sua and Sia felt a chill for the first time in their lives as they looked at the eyes of a predator that had not yet exposed its teeth, looking at its prey that had no idea what it was.
'This is my first time feeling like this... Let's calm down... After all, you are a true majo too. No matter how strong you pretend to be, you can't compete with the techniques of training countless females!'
Sua and Sia were embarrassed by the sensation they felt for the first time, but since it was their turn for at least 40 minutes, they did not worry and gave orders to Taeyang.
"Hehe❤ Oppa, you have a perfect body~ It's different from other weak men❤"
"That's right❤ Your dick is big and you might be the first to endure our caress for 20 minutes❤."
"Hmph. I don't care if I do that for 100 days because it doesn't feel good."
"Hey~ Really?❤"
"Then this time I'll make you feel really good❤"
Taeyang stood proudly, Sia facing towards his cock, and Sua facing towards Taeyang's butt.
'I don't know if he will cum but... I guess Sia can do well, right?'
This was a technique that completely degrades the female masochists they often use, stimulating their front and back holes at the same time and bringing them to climax in humiliating pleasure.
"What I'm doing now is that even my lawyer sister couldn't stand it, and she's changed like that, so prepare yourself, Oppa❤"
"That's right❤… Among the females we train, there is no one who can withstand this... Of course, not even you❤"
"Hmph! I'll make you cry in front of me in 40 minutes."
"I'll look forward to it, oppa~❤"
Sua snorted at her Taeyang's comment and answered.
'Huh? Are you ready, Sia?'
However, when Sia looked at Taeyang's comment as if she didn't understand her blushing and swallowing her saliva, Sia also came to her senses and looked at his cock.
Now Sua can't see Taeyang's face because she was behind Taeyang's back, but Sia gets angry and sees Taeyang's face looking down at her.
Without realizing it, her masochistic instincts were heightened, and she became excited.
Sua, who was unaware of this fact, used her usual cocky tone and provoked him...
"Then❤ Slurp❤ Jupup❤ Hmm❤ Kiss❤"
Swoosh…
"Ugh!?"
Without hesitation, Sua put her mouth towards Taeyang's asshole and started rimming, grabbing Taeyang's cock and shaking it.
'Man's butt… Maybe better than I think❤'
Even though she, who can control other women to the point where she was a professional trainer, seems to be excited by this kind of behavior, and unlike before, her pussy was dripping with pussy juice.
'Let's quickly train this Oppa and use him as our exclusive biological dildo.'
As a female, she seems to like Taeyang, an S male, so she doesn't even look at him normally, but she expects to use Taeyang to have lesbian incestuous sex with Sia.
"Then I'll make your dick feel good too, oppa❤ Kiss ❤ jjuup❤ Kiss❤ Slurp❤"
Like Sua, Sia put his dick in her mouth to stimulate his dick, but since her small mouth wasn't enough, Sia also used her hands to stimulate his balls.
"Ugh!? What kind of techniques are these bitches using?"
'No matter how much you endure, you won't be able to beat us since you're a Masochist man... But sucking Oppa's butthole might be better than I think❤'
Sua, who was confident that they would win based on Taeyang's reaction, regained her composure and began to tease Taeyang asshole again with her tongue.
