Part 1


Serene, Cierra, Fia and Lina sat at the small, wooden living room table looking serious. Or at least, Serene, Cierra and Fia were looking serious. Lina was mostly just looking confused.

"You know..." Cierra said slowly. "This isn't completely unprecedented."

"What? Yes it is," said Serene hotly. "It's the first time anything like this has ever happened."

"To you," said Cierra. "But I heard frogs and chicken can change themselves when they have to. When population levels are low or something."

"What population?" said Serene.

"Oh. Sorry," said Cierra.

Serene waved a hand vaguely. "It's OK. I'm the last Arc. I'm used to it."

"So... err..." Cierra began, "what do you think of my hypothesis?"

"It's the craziest thing I ever heard," Serene replied. "But then again, you're trying to explain something that's pretty crazy anyway."

"I think I should hit the library at the Crystal Caverns," Cierra said thoughtfully. "Maybe they've good some good books on Arcs. Oh, and I'm sure Soala and Claude would be willing to help out."

"No," said Serene. "You're not gonna involve them."

"But there'd be more chance of success," said Cierra.

"I said no," said Serene.

"Well, if you're sure."

"I'm sure."

"Then I'll be going," said Cierra, standing up determinedly. "I'll be back when I find something. Or when it's time for dinner."

Serene smiled a bit indulgently. "Yeah, sure. Thanks."

Cierra reached out to take Serene's hand and squeezed it for a moment before walking out of the room.

"Well," Serene sighed. "If anyone needs me, I'll be up in my room."

Serene flapped her bat-like wings and flew off, taking care not to bump her head on the low ceiling.

Lina blinked. "Uhm... what was that all about?"

Fia didn't respond. The thoughtful look on her face suggested that she hadn't even heard the question.

-----

Serene landed quietly in the room she shared with Cierra. The wooden floor hardly creaked, which had been totally against Serene's expectations of houses built in trees when she first moved in. Serene sat down heavily on her bed and looked vaguely in front of her. She really didn't know what to do. On the one hand she didn't really feel like doing much of anything, but on the other hand this morning's unexpected surge of adrenalin still hadn't left her system so she couldn't really sit still either.

Serene's wandering gaze fell on Cierra's man-sized mirror and lingered there. The reflection of a female Arc with her elbows on her knees and her chin in her hands certainly looked normal enough, but that was only because the image was sitting down.

Serene sighed, stood up and looked at the mirror again.

Yep, that was no ordinary reflection any more. The female Arc's skintight black shorts were definitely bulging where female Arcs usually don't bulge. It wasn't much of a bulge and if she'd been wearing something a bit looser it wouldn't be bulging at all. But she wasn't wearing anything looser and it did bulge.

Serene began walking very slowly towards the mirror. Without really thinking about it on any conscious level she began pulling off her clothes one by one, leaving something of a trail on the floor behind her. By the time she reached the mirror she was stark naked.

The Serene in the mirror looked at her, as if it taking in her body parts one by one. Blueish-purple hair. Dark purple eyes set in a tomboyish face. Pointy ears. Nice, trim body. Pert breasts. A pair of fully controlable black wings sticking out of her back, each with a bony white tip. Flat stomach. Inward bellybutton.

Serene reached down to pull something out of the way.

Tight vagina. Rather small hips. Good legs. Feet that were bit fragile because she spent so little time standing on them.

Serene.

But since this morning Serene now also came with...

... a penis.

Serene looked rather dumbly at the thing. She didn't know if it could be considered big or small. She did know that it would likely get bigger every time she got aroused, but she didn't know by how much and didn't really care either. Before today, the phallus had never been a part of Serene's life and she'd been quite happy with that.

But she wasn't freaked out. That was the weird thing. Oh, she'd been shocked and surprised when she woke up, but that was about it. Yesterday Serene hadn't had a penis and now she did. Those were the plain facts. Going into denial about it was almost as stupid as getting all hysterical over it. And in the extremely likely event that Cierra's research turned up nothing she'd better get used to it.

"Oh."

Serene turned around sharply to see Fia's blushing face sticking out of the hole of the stairs. Serene's first instinct was to grab something big enough to cover up her essential bits, but she soon realised that most of those were lying at the other side of the room near her bed. So instead Serene went for the tried-and-true tactic of being annoyed.

"Knock, will you?"

"You don't have a door," said Fia. Even though she was still blushing, her eyes remained fixed on Serene's naked body.

"Well, try to make some noise when you come up here. I'm not really in the mood for even more surprises today."

"Sorry. Do you want me to leave?"

"Depends. Was there something you wanted?"

Fia climbed up the rest of the stairs. Serene thought she felt a small... twitching as she watched the young woman enter her bedroom. The Arc quickly turned back to the mirror only to notice her new appendage had grown slightly in size. It wasn't long before Serene could see Fia's mirror image standing behind her own.

"I... just wanted to see it with my own eyes," Fia said.

"What, you didn't believe me?" Serene said in what she hoped was a joking tone.

"Of course I believed you, but..."

"But...?"

Fia put her arms around Serene's waist and the Arc soon felt the green-haired woman's body pressing against her back. In order to avoid being crushed, Serene's wings folded themselves around her body and their leathery skin covered her breasts. She could also feel her cock beginning to stir and her pussy becoming moist, which was ludicrous. Sure, she'd been aroused by the other girls before, sometimes even to the point that she really need to excuse herself and go have some private time. She just wasn't sure why it was happening now.

"I just want you to know I don't care," Fia said softly. "We all love you and this won't change that."

Serene smiled weakly. What the hell was she supposed to say to something like that?

Fia's right hand drifted down and came to rest on Serene's new dick. She opened her mouth.

"If you're going to something really cheesy like how this is just one more bit of me to love, I'm really gonna have to ask you to leave," Serene said.

Fia smiled. "Then I won't say anything." She took Serene's cock in her hand and began stroking. "Does this feel good?"

"Mmm."

"I... If Cierra doesn't... I want you to feel comfortable with yourself."

"And... you think... this will help?" Serene asked, her cock definitely going hard and her pussy getting very wet.

"I don't know," said Fia as she continued to stroke Serene's shaft. "Does it?"

"Well it-" Serene gasped. "It does feel good."

Fia smiled. "I'm glad."

Serene watched the winged girl in the mirror's face become flushed and her veiny cock becoming hard and pointing upright because of the green-haired young woman's fingers stroking it.

Serene closed her eyes and moaned when Fia's free hand moved up to caress her breast. Fia could only caress and squeeze the bottom curve of her breasts because Serene's wings covered the rest, but the added sensations would have been enough to set her whole body on fire if that hadn't been happening already. Fia nuzzled her and softly kissed and licked her neck.

Breathing so heavily she might as well have been moaning, Serene felt her whole body go weak, supported only by Fia's. Heat radiated from her neck, her breasts, her cock and her pussy, filling her. Serene turned her head towards Fia and found her lips pressing against hers. Serene kissed her deeply and for a brief moment she'd almost forgotten the precum oozing from the tip of her cock or the juices trickling down her leg. Fia's tongue pressed into Serene's mouth and the Arc happily accepted it. Their tongues lapped at each other until, panting, Serene had to break the kiss. Fia's warm hand was still wrapped around the hot flesh of her cock now made more slippery with her precum and even though Fia stroked calmly Serene still felt herself inevitably heading for something. She leaned forward, her left hand pressing against the mirror, her wings unfolding just enough to allow her right hand to fondle her own breasts along with Fia's left hand.

Serene's moans became louder and more continuous, only cut off whenever she clenched her teeth. The orgasm that had been building up came and Serene shuddered, her twitching cock shooting streams of semen that all landed on the mirror. Fia kept jerking her cock throughout the orgasm, as if she was trying to get as much cum out of her as she could.

Once she calmed down somewhat and her breathing returned to a mere rather heavy, Serene straightened up somewhat, her wings once again folding across her breasts. She kissed Fia again and although it was less passionate, it was filled with exhausted love. It took a moment for Serene to realise that Fia hadn't taken her hand away from her cock yet and was in fact still stroking it, trying to stop it from going completely limp. Serene moaned softly and found herself completely hard again.

Fia broke the kiss and blushed slightly, an unspoken question in her eyes. Serene replied with a smile that was half affectionate, half smirk.

The two girls drifted towards Serene's bed. Fia lay down on her back and looked up at the naked Serene towering above her. Serene took Fia's expansive green dress and pushed it up until it was folded bunch somewhere around the girl's waist. She reached down, touched the Fia's white panties and wasn't at all surprised to find them wet.

Fia gasped when Serene rubbed her panties and then begun blushing when the Arc leaned down to lower them. It was a cute blush spreading across the young woman's face, but Serene couldn't help but find it a bit funny considering what Fia had done more moments ago.

Fia's glistening pussy now open before her eyes, Serene couldn't help but lean in and kiss it. Fia moaned softly as Serene continued to kiss and lick her slit. Fia groaned and her back arched when Serene slipped her tongue into her pussy, savouring the taste of the girl's flesh and juices. Fia began panting as a quietly smiling Serene drank from her. Serene withdrew her tongue from Fia, licked her lips and looked up with an impish smile. Fia looked back with eyes darkened with lust.

Serene crawled on top of Fia until they were face to face, her cock pressing against Fia's slit. Fia threw her arms around Serene's shoulders and drew her down into a kiss. While Serene's tongue played feverlishly with Fia's, the Arc poked her dick at Fia trying to find her entrance until it suddenly slid into her.

Both girls moaned when Serene's cock filled Fia's pussy. They were both hot and wet and slippery and Serene slipped in and out of Fia with ease. Fia's eyes unfocused more and more with Serene's every thrust until they closed and her lips parted and moaned.

Serene breathed heavily and tried to stay focused on fucking Fia, but found it difficult. Fia's hand had been one thing, but the girl's tight pussy was quite another. Fia squeezed her cock beautifully apparently without even trying. She could feel the hot, urgent pleasure building up inside of her again. She tried to ignore, or at least press it down long enough for Fia to come. But the girl's whole writhing body wrapped around her cock was simply too powerful. Serene could feel her orgasm building up, concentrating at the base of her cock, waiting to fill Fia's womb.

"Fia..." Serene panted, "I'm..."

Fia suddenly wrapped both her arms and legs completely around Serene, pressing the Arc's lips onto her own and pushing the girl's cock further into her pussy. The sensation overwhelmed Serene and she came, her semen shooting into Fia. Fia tore her lips away from Serene's and moaned as she too apparently came, her pussy clamping down on Serene's cock like a vice as if wanting milk every drop of cum from the girl.

Their orgasms passing, Serene collapsed on top of Fia, struggling to regain her breath. Her cock became limp and left Fia's pussy almost on its own. For a moment, their combined fluids flowed from the green-haired woman slit and pooled on the bed between her legs.

The girls gave each other a tired kiss and then smiled at each other.

"You know," Serene said, "if Cierra was..."

Fia put her finger on Serene's lips and smiled gently. "I'm rather hoping she was," she said.
