To be more precise, an awakened individual possesses a particular type of ability that can be considered a medium or a device which takes Synergy as input and provides output based on the device's function.
To understand it more clearly, one's ability can be considered a tunnel that has a particular shape.
According to that shape, when air passes through it, it provides output in that particular direction.
In the case of an awakened individual, that tunnel can be made only once, so further reconstructions are generally impossible, though there are definitely exceptions in most cases.
So, the tunnel, which represents an awakened ability, takes the air—here referred to as Synergy—and produces an output.
However, that output is the same as the functioning of the tunnel, without having anything extra attached to it.
Although the amount of Synergy can decide the concentration of the output, it doesn't change the result.
In the end, if a tunnel had a function to heat up the air, then the output would be heated air, not cold.
However, Avendial's ability here was a game changer.
This is simply because it partially destroys that particular tunnel (awakened ability).
Of course, it doesn't completely delete it; rather, it causes cracks and several breakages, damaging at least 80% of its stability, similar to how a tunnel's wall would collapse.
Still, the passage (the hole) remains intact, though not completely.
Once his ability—though it could be considered a curse—was understood, he learned to use it to his advantage.
After introducing his bodily fluid—which could be blood, semen, saliva, or anything else—though blood was much costlier than semen, so in the case of women, he would mostly prefer that option—an individual's awakened ability gets partially destroyed.
Naturally, the Synergy that had been passing through that tunnel or medium since earlier—given that this particular awakened ability is born from that Synergy—would try to reinforce it with much strength, making it sturdier so it doesn't break again.
And there, that individual goes through a second awakening.
This awakening provides an updated, upgraded, and stronger version of what they initially possessed.
In simple terms, the tunnel's concrete walls can be considered the features of the ability, while the path of the tunnel symbolizes the type of ability—in the case of Aria, it is Appraisal—which remains intact.
This means that during her second awakening, she retains the same appraisal ability, but the walls—meaning the features of that ability—are enhanced and much better than before.
This was the theory that Avendial had learned on his journey, knowing well how his ability could be used to provide him an advantage, even though it was a curse—a curse that could inevitably provide him an advantage.
But Avendial was relentless.
He captured one nipple between his teeth, tugging gently, and then laving it with his tongue.
Her entire body jerked, her head tilting back as a guttural moan ripped through her.
"Ah... Aven... please..." she was begging now, her voice breathless and broken.
The sound was like music to his ears.
He switched to her other breast, giving it the same attention, his fingers squeezing and kneading while his mouth continued its merciless assault.
Finally, he lifted his head, his gaze meeting hers.
She looked utterly wrecked, her pupils blown wide, lips parted as she gasped for air.
There was a wild, desperate look in her eyes, as if she were teetering on the edge of something she couldn't quite understand.
Avendial didn't let up.
His hand slid lower once again, reaching for the waistband of her jeans.
This time, there was no resistance.
She lay there, her body trembling, completely at his mercy as he slowly peeled the tight fabric down her hips.
His eyes glinted with hunger as he took in the sight of her—flushed, panting, and glistening with sweat.
It appeared that his hunger was more towards his ambition to achieve the goals he wasn't able to accomplish in the past than the hunger of her body.
He paused, letting his fingers dance along the edge of her panties, watching her reactions.
She was completely lost now, her mind a haze of pleasure and desperation.
Her hips lifted almost instinctively, seeking his touch, her lips parting in a soft, breathy moan as she looked up at him with pleading eyes.
"Good girl," he murmured, his voice a deep, rumbling purr as his hand in a single motion pulled her panties down to her thighs.
"Kyaaa~! W-wait?!"
