When Rain activated the Eyes of Endless Lust, he noticed that everything was largely unchanged, except that Astrid was surrounded by a faint purple aura and a small window was visible next to her.
[Lust: 18]
Without waiting for his question, the system explained.
[It's another of the Eyes' abilities to see a woman's level of lust.]
'It's convenient, but why is it so low?'
Although Rain could no longer see the insatiable hunger in Astrid's eyes that she had when they first met, he could clearly sense that her gaze on him was still far from that of a master on a disciple.
[She's excited now, but it's more like the excitement of finding something new and unknown rather than lust.]
"Do you want to try it yourself?"
Astrid asked, seeing that Rain still hadn't reacted to her statement.
Even after activating his Eyes, her appearance did not change in any way, still maintaining her excited demeanor and proud expression.
"Yes."
'Then all I have to do is keep using them.'
With that, they began Rain's training: he did his best to repeat her technique exactly, while Astrid professionally identified any faults and pointed it out to him, advising him how he could correct it. Sometimes, when Rain was doing particularly well, she would nod her head contentedly and show him new moves.
A few hours later, as Rain finished his next attempt to replicate Astrid's technique, she said in a voice that was really excited and happy.
"I wasn't wrong to choose you! You can truly be considered a sword genius and if you continue on your path, one day you will definitely surpass me."
Rain looked at her with a strange mixture of emotions in his eyes.
Since he was good at everything from childhood, he never tried to dwell on one thing, preferring to develop in all directions, be it martial arts, magic, or alchemy. Among them, swordsmanship was just one of the many activities he occasionally paid attention to if he felt it was necessary.
The thought never even crossed his mind to fully dedicate himself to the way of the sword or anything like that.
However, whether it was the presence of such a master in front of him or his eagerness to gain power in this new world as soon as possible, Rain felt an unusually fast progress, even for him, and began to feel a natural attraction to wielding a sword, as if it was the path he needed.
Of course, he wouldn't have minded anything else, but from now on Rain decided to devote more time to his sword practice.
'Anyway, I've got better things to do right now.'
Throughout their entire training session, Rain never stopped using his Eyes of Endless Lust for a second, and it paid off.
Astrid's eyes began to lose their focus more and more often from the sword in his hands, moving lower down his body as if drawn to something else.
There was a slight blush on her cheeks and slightly rapid breathing, which under normal circumstances could have been written off as the effects of intense training, but Rain knew it wasn't. And the reason for his confidence was right in front of him.
[Lust: 29↑]
According to these numbers, her level was slowly but surely rising, even without any additional action on his part. It made Rain realize that these Eyes really deserved their name, for they could do that to a woman whose strength he couldn't even fathom.
But Rain wasn't completely satisfied.
The problem was that her lust was stuck at level 29 and wouldn't go up again no matter how much Rain used the ability. And he acutely felt that level still wasn't enough.
'That can't be the limit for divine Eyes, can it? System, can you explain what this is about?'
[Host, 30, 60, and 90 are thresholds after which the target's lust spikes to a completely different level. To overcome it, you must increase the target's arousal by yourself, for example, by initiating contact or making one of the woman's dark desires a reality.]
'What about the value of 100?'
[I would advise you never to take a woman's lust to this level, especially if she is stronger than you. Otherwise, you are bound to be raped, regardless of your condition, and perhaps something even worse will happen.]
Rain cringed at the thought of someone dominating him and disposing of his body as they saw fit. From the moment he realized that he'd been manipulated by the World's Will for most of his life, he'd developed a natural aversion to other people's control.
So Rain decided he shouldn't cross that line. At least not until he was strong enough.
He turned his attention back to Astrid.
"There are a couple things I still don't understand, Master."
"Is there something you don't understand?"
"Yes, it would be best if you came over and helped me with that."
Astrid was a little surprised, but didn't hesitate to approach him.
Her clothes were slightly drenched with sweat, pulling her body even tighter and allowing Rain to see the outline of her nipples on her breasts.
"This move."
Rain began to demonstrate what he had recently learned, leaving some gaps in his technique, enough to get Astrid's attention but not too big to arouse her suspicion.
"All you need to do is..."
Astrid began to explain, while simultaneously correcting his body position. At the same time, consciously or not, she pressed her tits against his shoulder, sinking it more and more between her peaks. From this distance, Rain could clearly see the tiny droplets of sweat on her exposed collarbone and neck, giving them an extraordinary sheen.
Rain could feel Astrid's hot breath hitting his ear along with her words, which he was no longer paying attention to, and his nose was constantly assaulted by her seductive scent.
One might not even mention that such varied stimulation turned Rain and his little brother on like hell.
[Lust: 35↑]
After making sure the lust level had increased, Rain wanted to start doing what he had planned, but was interrupted by a sudden sensation down below.
Tilting his head, Rain noticed Astrid's beautiful hand with neatly trimmed fingernails gently tracing the bulge on his pants. At the same time, a sweet voice whispered in his ear.
"What a bad disciple you are, hiding such a great sword from your master❤️"
At the same moment, a series of notifications sounded in Rain's ears.
[Lust: 36↑]
[Lust: 37↑]
[Lust: 38↑]
[Lust: 39↑]
[Lust: 40↑]
Her level continued to skyrocket and her embrace grew tighter and tighter as her hand squeezed his cock harder and harder.
