Note: So, yeah, if the last chapter was any indication you know what to expect here, but still, as always, some lewdness ahead.

Ash
Ash was conflicted.
On one hand, the lust in her nature made it so that she was eager to get this going. On the other, she had underestimated how awkward this would be to do with someone who she hadn't seen in a sexual light until about four minutes ago.
It was especially jarring to be doing anything like this with Yumi, despite the fact that she was beautiful because up until now Ash had spent far more time being impressed by her rather than being turned on.
"So," Ash said as the two of them remained sitting on that hill, demons moving through the waters in the distance, "what do you want me to do?"
"I have no idea how any of this works," Yumi replied with a shrug.
"Right. Well, uh, shit, I guess I could finger you or something, get over here," Ash said, wiping her hands on the few clean spots on her clothes to clean them up.
With some awkward shuffling, Ash directed Yumi to where she was sitting in front of her, but with her back to Ash's chest. If they were going to do this, Ash didn't want to stare into a pair of nervous eyes the entire time.
"... No offense, but you smell terrible," Ash muttered.
"Yes, and you, on the other hand, smell like lilies and sunshine," Yumi mumbled sarcastically as Ash parted her legs lightly.
"Fair enough, fair enough," Ash took a deep breath as she felt Yumi's back press against her chest. "Okay, so, listen, I'm going to start, let me know if you don't like it, you don't feel comfortable, you change your mind or whatever."
"How long does this take?" Yumi asked, turning her head towards her.
"Uh... Honestly, I don't know, I'm usually too busy being horny to really measure the time."
"I see..."
"So, just lean back against me, close your eyes, relax, and yeah, with any luck in the middle of all this awkward shit you'll at least cum."
"I will what?"
"Nothing."
Finally, after so much stalling, Ash nodded to herself and tried to steel her nerves as she reached between Yumi's legs. She placed her other hand on Yumi's breasts and felt the woman flinch when she touched her.
She was practically trembling. Admittedly, there definitely was something alluring about the thought of seeing a woman like Yumi, who was usually so serious and confident, be completely out of her element like this.
In a word, it was cute.
Particularly, the way Yumi shivered a little when Ash's right hand reached her lower lips and her fingers brushed against them was adorable. It made Ash want to tease her a little just to see what other reactions she could get.
It was slightly concerning how quickly she managed to forget that they were in the middle of a poisonous swamp with bloodthirsty demons all around them.
She drew circles on top of Yumi and the Zayama took a sharp breath. Then, after Ash lifted her hand to her lips and lubed up her fingers with her own saliva, she went back to that spot and let her digits push in just a little, her other hand massaging Yumi's chest.
At that, Yumi gave a slight gasp and Ash chuckled lowly.
"... Kinda sounds like you're enjoying this more than I thought you would. Is this good?" She asked.
"... Just ge-" she cut herself off when Ash touched her clit, taking a deep breath and staring down at Ash's hand. "Just get on with it," she said with a flushed face.
"Hahaha," Ash laughed. "Got it, got it."

Keiko
At this point, Keiko was getting restless. Now that her condition had become slightly better and she was feeling far less sick than before, the boredom and anxiety of sitting around in the Grey Chamber were really setting in.
As she sat by Metsumi and the others, watching soldiers walking in and out of the palace, some covered in blood, some fresh and about to fight, she felt some anger bubbling under her skin.
I should be out there with them, she thought. At least now that I'm not as sick, I should be taking advantage of this moment. Instead... She sighed. I'm stuck in here.
She wondered which of the deities influenced this outcome. If her pregnancy had simply been a prank done unto Ash from any of the gods. Still, she knew that if she were to tell the others that she wanted to go out and fight, she'd probably be tied down to the same bed Kaori was currently on.
So, all she could do was wish she could be out there, helping the soldiers defend the city, or maybe helping Ash as she closed one of the portals with Yumi.
Hm... I wonder how that's going, she thought. I hope they aren't having too much trouble.
"Um..." A voice suddenly said beside her and at first, Keiko didn't think she was being addressed. However, as a small hand tugged on her left sleeve, Keiko turned towards it.
Luvine was standing there, a nervous look in her eyes as she quickly put her hands behind her back when Keiko turned toward her.
As Keiko hadn't expected this, she was a bit surprised.
"Yes?" Keiko asked.
"I... I wanted to ask you something..." She mumbled.
"Oh. Uh, sure, go ahead."
Keiko hadn't spoken too much to this girl, as Ash had clearly made herself responsible for her for the time being. However, while Keiko was waiting for her to continue, she really felt like she was looking at a much younger version of her friend, only shy and scared of her surroundings.
"H-How did you meet Ash?" Luvine asked meekly. Keiko blinked.
"Why do you want to know?"
"Um... You're nice to her. Even though she's like me..." Luvine muttered and Keiko slowly realized what was going on.
Luvine, an ostracized half-demon, probably didn't understand how Ash had gotten where she currently was. Her friends, her status, it was all likely baffling to Luvine. Of course, she'd want to know about Ash's life. As Keiko got where Luvine was coming from, she chuckled a little and then nodded.
"Okay. Sit down, I'll tell you a little."

Ash
One thing had turned into another and after a short session of "hand training", as Ash liked to call it sometimes, she had now knelt down in front of Yumi, using her tongue.
Yumi was fully laid down as Ash dove between her legs, closing her eyes and trying her hardest not to focus on the awful smell of the dirt beneath them. On the bright side though, having eaten three girls out by now, Ash had decided it was one of her favorite things to do. She liked Yumi's taste and, if they weren't in this swamp, she figured her scent would be nice as well. Most of all though, she liked the reactions she got from her.
As a violet aura had started coming out of Ash, she grinned when Yumi gave a muffled moan, her lips tightly shut as Ash dragged her tongue over her.
"Almost there," Ash whispered as she looked down at her own body. Soon enough, she felt herself changing. Normally, she was so distracted by this point that she would completely miss these moments, but as the whole purpose of this was to get her in her Lust Demon Form, Ash was aware of what was happening.
She felt her hands change, then a pair of wings sprout at her back, and then, of course, her tail sprouted out from her lower back. Yumi looked down at her with some surprise and Ash smiled.
"See?" Ash chuckled. "This wasn't just an excuse to fuck you, you know."
"I-I see..." Yumi took quick breaths as she replied. "Are we done?"
"Not yet," Ash responded. Remembering her past trysts, she elaborated, "if I don't get off, I'll just revert back to normal."
"Oh. So, what must we do?" Yumi asked.
"Well," a bit of seriousness slipped into Ash's tone, "shit..."
At that moment, Ash remembered the talk she had with Magia almost a month ago regarding this very form. So, she said that it's based on my orgasms, if I remember correctly. That, if I don't get off, I'll turn back, but if I do get off, while in this form, I'll go all the way up to Lust 4. But... She paused. If I remember this right... I have to cum inside of her for this to work. Crap.
This obviously mattered because Ash already had gotten one girl pregnant thanks to this form. She didn't like the idea of having the same thing happen to Yumi.
Still, it seemed like the only answer. Without this, they really didn't have a chance at getting through to the beams. So, cursing her own condition, Ash looked up at her.
"I need to put this in you," she said, gesturing at her tail. "Then... Yeah, after a while, it'll be done."
"Uhm... Will it hurt?"
"A little, but Keiko said she liked it after the initial pain."
"Keiko!?" Yumi asked, shocked. "You did this with her?"
"... We've done a lot together, anyway, yeah, if you don't want to stop here, I'm going in."
"I... Sure," Yumi laid back down and closed her eyes. "Go ahead."
"... Alright."
And so, with that, the last step began. Ash gently pushed her tail inside of Yumi and the Zayama clearly held back a whimper, but Ash kept going. It felt amazing, the walls surrounding her tail were warm and tight to a point where Ash herself was breathing heavy.
"Oh my..." Yumi muttered as Ash continued.
And, at that point, as Ash's desire for her grew exponentially, so too did the rate at which she pushed her tail into her until finally Ash's abs clenched and she felt something pour out of her tail, and into Yumi.
And with that, as she retreated, she was locked into her Lust Demon Form, as she'd wanted.
Yumi took heavy breaths. Ash did the same, reaching down and extending a hand. Yumi took it, and both of them stood up.
"There..." Ash laughed, feeling demonic energy surging inside of her.. "Done."
