The viscous fluid composed of the Joy Factor quickly covered half of Tristana's buttocks.
During this process, Tristana could clearly feel that the connection between the fluid and her body was inextricably tight. In fact, it basically felt like a brand-new layer of her own skin.
Whether it was Faen's palm pressing down, the breeze blowing past, or the water flowing around her, Tristana could clearly feel that unique, incredibly sensitive and meticulous sensation.
At first, Tristana thought she had mostly gotten used to this feeling, but immediately after, her eyes snapped wide open in sheer shock.
It went inside.
Tristana could vividly feel Faen's finger slipping inside—sliding right into her body through that tiny little mouth down below.
This made Tristana incredibly nervous and anxious. She ultimately cast an uneasy, fearful glance at Faen behind her. But Faen maintained his usual expression. He merely spread her pussy petals apart with his fingers and said unhurriedly:
"Calm down. The new underwear needs to bond tightly with your body. Although your little mound is very smooth, there are still some folds and crevices inside your flower petals. If I don't spread them open, I won't be able to cover them completely."
Hearing Faen's words, Tristana didn't even know how to answer. She could only purse her lips, staring at Faen with a face full of intense nervousness.
Fortunately, Faen didn't disappoint Tristana. Although he teased her by blowing a breath of air into her pussy petals—causing Tristana to shiver wildly all over—he didn't push too deep. Once he finished covering her buttocks, he removed his hand.
Immediately after, that layer of Joy Factor clinging to Tristana rapidly transformed into a leathery black color, even reflecting a glossy sheen under the sunlight.
Although the process made Tristana feel incredibly ashamed, now that it was over, she relaxed. Standing on the ground, twisting left and right, she curiously inspected her nether regions.
There were no flashy decorations; it was just a glossy, leathery black.
Although it gave the impression of a suffocating, airtight latex suit, Tristana could actually clearly feel the air brushing against her skin and the water flowing over it.
Moreover, exactly as Tristana had felt, this membrane bonded with her flawlessly. Spreading her legs, Tristana tried to pry open her nether regions with her hands.
What greeted her eyes was the black latex almost perfectly outlining the contours of her delicate flower petals. However, it only revealed the outer labia; because it was completely sealed, the path leading into her flower room in the center was completely blocked by the black latex.
Thinking this, Tristana breathed a sigh of relief. She then looked at Faen, pointed at her nether regions, and said, "Then doesn't that mean I won't be able to go to the bathroom anymore?"
"No, it's very simple."
Sensing Tristana's confusion, a smile curled on Faen's lips, and he gently snapped his fingers.
Immediately after, before Tristana could even react, her sealed nether regions popped open exactly like a burst bubble, vanishing completely with a snap.
Because Tristana had just been curiously checking to see if she was blocked up, she was still holding her flower petals spread open with her hands.
Stunned for a moment, meeting Faen's gaze while looking down at her own wide-open nether regions, Tristana let out a sharp scream.
To this, Faen simply said with a face full of helplessness, "Speaking of which, Tristana, aren't you being a bit too nervous?"
"How can I not be nervous?!" Hearing this, Tristana looked at Faen anxiously and said:
"We aren't a couple! If it were just a massage or something, I could let it slide. But now... now Instructor has touched me there, and you even stuck your finger inside! Even if it was just a tiny bit...
"Even if Instructor wants to do it, that's something we should only do after becoming a couple, and after we get married!"
By the end of her sentence, a look of solemn seriousness had appeared on Tristana's face.
In response, Faen blinked and asked, "So is Tristana very angry?"
"Eh?" Hearing this, Tristana froze, then scratched her head and said, "Angry... well, I'm not really angry... because I actually think Instructor is a pretty great person. But we aren't a couple yet, so even if I think Instructor is nice, we still can't do things like this."
"I see, I think I understand what you mean now."
Hearing this, Faen nodded, but then added, "However, I know many elite warriors, and they absolutely do not share this mindset. Or rather, although some of their views are similar or identical to yours, in other aspects, they are completely the opposite of you."
"Eh? Really?!" Hearing Faen's words, and hearing that the mindset of elite warriors differed from her own, Tristana was slightly shocked. She looked at Faen nervously and said:
"No... no way, right? Or are you just lying to me, Instructor?"
Meeting Tristana's suspicious, wide eyes, Faen shrugged and said, "Since you said that... then let's pause our training for a bit. I'll take you to meet a few elite soldiers, what do you think?"
"Can we really?!" Hearing this, Tristana's eyes sparkled with bright light, and she said excitedly:
"Of course I have no problem with that! But Instructor, you better not lie to me! If those soldiers can't even earn my approval, then I'll definitely think Instructor's skills are lacking!"
"Of course, no problem." Hearing this, Faen smiled, then looked at Tristana and said, "But there is a catch. If you think they aren't good enough, I'll adjust my teaching methods and follow your lead—I'd even be fine with letting you train me.
"But if you agree that those soldiers are the absolute elite of the elite, then what are you going to do?"
Hearing this, Tristana's large eyes darted around. She gritted her teeth and declared:
"If that's truly the case, then no matter what Instructor wants to do to me, Tristana will do it immediately!"
As she spoke, perhaps afraid that Faen wouldn't believe her, Tristana added one more sentence: "I'm serious! I'm not joking around!"
"Haha, excellent!"
Hearing Tristana's answer, Faen laughed out loud. He tossed her pants back to her and said, "Then let's get ready to move out, and see if those elite soldiers I know truly live up to the title of 'elite' in your eyes!"
"Hooray!" Tristana quickly put her clothes back on and followed eagerly behind him.
