Grissel knew that a True Witch like herself would not be able to keep Vaan for herself. A person like Vaan would be quickly taken away by a Senior Witch once words of his pleasure skills spread in town.

Suddenly, she remembered that Vaan said he did not work at the brothel anymore. Perhaps, he was already serving under a Senior Witch.

'Such a pity…' Grissel thought.

Although she wasn't sure why Vaan returned to the brothel, at the very least, she felt fortunate to have Vaan to herself for the night.

"The fourth level of pleasure is…" Vaan continued to explain the last two levels when he was suddenly interrupted.

"W-wait!" Grissel gasped for breath before she quickly said, "You can just explain it. No need to demonstrate it. I fear I would lose my mind if I experience anything greater than the third level."

Although she could not see Vaan's expression with her back to him, she could sense the confidence in his voice.

This man's pleasure skill might just be at the fourth level. There's a chance that it might even be greater than the fourth level!

If she experiences that level, the sensual pleasure of that level will enslave her, and no man except Vaan would be able to satisfy her from then onwards.

"Alright," Vaan smiled.

He resumed moving his hips and thrust his rod into Grissel's cave repeatedly like a piston, allowing her to experience the pleasure of the third level as he continued to explain the five levels of pleasure.

"The fourth level is Dominion. Just as you feared, you will be enslaved to this feeling once you experience it. Whether it is my rod or I, as a whole, you will only desire them and no other unless you can find another person with fourth-level pleasure skill."

"Mmm~ That sounds rather scary. Ahhh~ I'm glad I chose to avoid the demonstration…" Grissel struggled to speak under the waves of pleasure that assaulted her.

Nevertheless, the bedroom was filled with nothing except the noise coming from the creaking of the bed, the thumping of their flesh contacting, and last but not least, Grissel's moans that grew with increasing intensity from Vaan's thursts.

After her first climax, her second and third following climax came relatively slower and not as easy, but still enough to leave her breathless and sweating—but from the intensity of their session.

As mana entered her body, it pushed out the impurities in the form of sweat.

Despite feeling invigorated by mana at the end of her third climax, Grissel felt like she would be too weak to walk properly for the following three days.

Even so, it was the least of her worries as a victorious smile hung on her face.

"Hehe, I did it!" Grissel exclaimed like a child as she boasted to Vaan, "You were wrong. I managed to survive three rounds without begging you to stop. Not so impressive after all—"

"What are you talking about?" Vaan asked nonchalantly before adding, "I did say you'll be begging me to stop within three rounds, but I didn't say it'll be three rounds of yours. It's three rounds of mine."

"But… you haven't even…" Grissel paled as the color was drained from her face. All her joy disappeared in an instance.

She glanced at the bedroom's entrance and began crawling towards it from the bed, but she was held in place by Vaan.

"Where are you going, my Lady?" Vaan chuckled.

"P-Please spare me…"

Grissel initially thought she had invited a handsome young man into her room to play with her, but she found out that the handsome young man was a wolf instead.

The role of prey and predator was reversed. She realized this when Vaan revealed his third-level pleasure skills.

"It's the first time I've seen a witch trying to escape the opportunity to grow stronger," Vaan laughed softly and added, "At your body's current rate of mana absorption, it won't take long for you to become a Senior Witch."

Hearing the term 'Senior Witch,' Grissel pursed her lips and abandoned her plan to escape. It was true that her body was absorbing mana at an exponential rate compared to her past sessions.

'Even if I end up not being able to walk for a whole, I must advance to Senior Witch!' Grissel gritted her teeth with determination.

Little did she know, Vaan had been secretly increasing his skill level and applying fourth-level pleasure to dominate her.

Even if she was just a True Witch, gaining a woman, or more importantly, an additional ally, might prove useful in the uncertain future.

'She's ready,' Vaan narrowed his eyes.

He began stimulating her erogenous zones to experience the full course of his fourth-level pleasure skill.

Grissel's sensitivity heightened, and her pores widened to accept a greater surge of mana pouring into her body.

"Oooh, I can feel it~! It's like the world is blessing me~! So much mana is pouring into me~!" Grissel suddenly exclaimed euphorically as the concentration of mana flowing into her body exceeded a certain threshold.

Her cumulation of mana grew at breakneck speed, far beyond any session she took at the Earthly Pleasure Manor or any other brothel for that matter.

"It won't be the only thing pouring into you," Vaan added.

"Don't you dare…"

Grissel wanted to resist, but she quickly hit her limit on the seventh climax and lost her sense of reason as Vaan unloaded his big dick energy, or rather, his yang energy.

Despite breaking through a small stage and becoming one step close to Senior Witch, Grissel was overwhelmed with fatigue and fell into a deep sleep.

The stimulation overtaxed her nerves.

Vaan tucked the soundly-asleep Grissel into bed neatly before wiping himself clean and getting dressed in preparation to leave for his own designated room.

He did not plan to explain the fifth level of pleasure, nor did he plan to demonstrate it. It was the level of true enslavement, Euphoria.

If he used it on Grissel, who was relatively more sensitive than the average witch, she would not achieve Euphoria but a Mind Break from the dopamine overload on her mind.

This was the horror he secretly discovered through his deduction and experience after mastering the Heavenly Massage.

It could reduce a highly sensitive witch into a mere puppet.

Ding!
