Biological Imperatives

Part 2


Cierra sat in a quiet corner in the Crystal Cavern's magical library. It had been pretty easy to find such a quiet corner since the library was pretty big compared to the very low number of people who used it. But even if she hadn't been able to find a little bit of peace and quiet, Cierra felt certain she wouldn't have been disturbed anyway. The book she was reading was simply filled with all sorts of fascinating stuff. None of it struck her as immediately helpful, but it was fascinating all the same.

"What're you reading?"

Cierra practically jumped in her seat and slammed the book shut. Soala looked over her shoulder and read the title on the leatherbound cover.

"Arcs: A Basic Biology," the purple-haired witch said. "There's nothing wrong with Serene, is there?"

"What? No, no of course not," Cierra said quickly. "As fit as always, you know."

"That's good," said Soala. "But why are you reading it then? It doesn't really strike me as interesting."

"Oh, I was just wondering why Serene..." Cierra stopped that sentence once she realised where it was going to end up. But by then it was too late.

"Why Serene what?"

"Why Serene... has... such... tiny wings," Cierra said and sighed with relief. "Yes, that's right. I wanted to know how she could have such little wings on her back and still be able to fly."

"They're not that small," said Soala.

"Compared to every other flying creature they're pretty insignificant, really," Cierra said.

"I guess that's true," said Soala. "So?"

Cierra blinked. "So what?"

"So have you figured it out?"

"Oh. Yes. Turns out Arcs are really magical. I mean, not magical like us, they're not natural spellcasters or anything, but they have a lot of magic in their bodies."

"And that makes their wings strong enough to fly?"

"I think so," said Cierra. "Or maybe the magic just makes their bodies lighter or gives them a personal gravity or something. Who knows with magic?"

"Well, us witches do," Soala pointed out.

"Right," said Cierra. "So I think I should probably go home and do some more research."

"On Serene's body?"

"Yes. No! I mean..." Cierra said slowly as she tried to steady her nerves. "I'm going to research Serene's body, but I'm not going to research Serene's body, you know?"

"Oh yes," said Soala, with a faint smile. "I think I know."

"Right," said Cierra uncertainly.

-----

"Well, it's not dinner time yet so does that mean you found anything?"

Cierra looked to see Serene sitting at the table, drinking a cup of tea.

"I didn't find a solution yet," Cierra admitted. "But I found a book I think might help."

"Well, I guess that's a start," said Serene. "Want some tea?"

"Sure. I'll just go put this book away first."

"No!" Serene exclaimed. "I mean... CoCo is busy cleaning our room right now and you know how she gets when someone disturbs her."

"Good point," said Cierra, sitting down at the table. "I'll just have some tea now then."

"OK," said Serene.

The Arc stood up and as she did so, her black shorts came into Cierra's view. The scarlet witch couldn't help but stare at the bulge. It seemed like a rather bigger bulge than it had been this morning. Blushing, Cierra tore her gaze away.

"So, where are Fia and Lina?" she asked.

"Fia went to go take a soak in the Undine Springs and I think Lina's out playing with Gill and Molan."

"So we got the place all to ourselves then?" Cierra said, not really knowing whether this was a good thing or a bad thing.

"Well, CoCo's still here," said Serene.

"Cleaning our room," said Cierra. "You said."

"Here," said Serene, placing a cup in front of Cierra before sitting down on her chair again.

"Thanks," Cierra said gratefully.

Cierra sipped her tea carefully and found it a bit too bitter for her own tastes, which probably meant it was just right for Serene's. She put the cup down before glancing at Serene, then away, then back again. Then she suddenly found herself fidgetting with a strand of her long red hair.

Oh, this was just ridiculous, some part of Cierra told herself. She'd liked Serene for a long time and she'd really liked Serene for quite a while as well. Now was not the time to start getting all nervous and flustered and hot around the girl. She was still Serene and just having a cock didn't make her magically more attractive.

Except... maybe it did, Cierra considered. If her hypothesis was right and Serene's body had changed in order for her to make lots of baby Arcs then her body must also be looking for suitable partners. So, obviously, Serene was probably mass-producing pheremones in order to attract as many fertile young women as she possibly could.

That didn't actually make it any better. Cierra liked Serene and she didn't want to start thinking of her as if she were some kind of automated breeding machine. For that matter, she didn't really want to start thinking of herself as a walking incubator, no matter how willing she was to play the role.

No, when she was going to have sex with Serene it would be because they would both really enjoy it and not because magical-chemical processes drove them to mechanically make babies.

Wait, shouldn't that have been 'if' and not 'when'?

Cierra glanced at Serene and felt determination settle in her mind. As well as a certain heat in pretty much every other part of her body.

No, not if. When.

And of course, an impish thought suggested, there was no rule that said that 'when' had to be somewhere in the far future, was there?

"You know," said Cierra, trying to sound casual, "maybe it would really things if I actually got to see how you changed."

Serene smiled wryly. "You're just saying that because you want to get into my pants, don't you?"

Cierra blushed. Had it really been that obvious?

"Well... yes..." she admitted.

Serene put down her own cup of tea. "In that case I think you should know Fia already beat you to the punch. And if that's a problem for you, then..."

"Why would it be a problem?" said Cierra. "I love Fia too."

"I had a feeling you would say that."

Cierra got up, walked around the table and sat down on the floor in front of Serene's chair. She grabbed Serene's shorts and tried to pull them down, but Serene's erection posed a brief problem. Soon enough, however, Cierra had exposed Serene's hard cock and her wet pussy. Cierra took off her long gloves and tossed them casually on top of the table. Then she reached forward with her right hand and let her fingers glide across Serene's slit and up to Serene's cock, leaving a glistening trail on the Arc's shaft.

Wrapping her hand around the base of Serene's cock, Cierra leaned forward and her tongue poked out to lick the girl's member. She could hear the change in Serene's breathing as the tip of her tongue traced around the girl's head. Serene leaned back in her chair, giving the impression of thrusting her hips forward towards Cierra. The scarlet witch kept lapping at the tip of Serene's cock until the purple head was all shiny with her saliva. Then she leaned further forward still and wrapped her lips around Serene's cock.

Serene tasted... kind of unspectacular. Her flesh was hot and hard in her mouth, but the taste was strangely not-there. Then again, Cierra hadn't taken Serene's cock in her mouth for its taste, she'd done it for the gutteral moan of lust filling her ears. Cierra wasn't at all sure how a girl went about sucking a girl's cock, but she had never let total ignorance get in the way of experimentation before and she wasn't about to start now. She sucked and licked and let her lips travel up and down Serene's shaft. Serene's moans became louder and more urgent, a sound that made Cierra pussy tingle with excitement. Serene's hand made its way under the brim of Cierra's floppy witch's hat and into her red hair. Cierra half expected Serene to force her head down onto her cock, but all she did was just hold her hair.

Cierra let go of Serene's cock with her hand, placed both hands on the Arc's hips and tried to take in as much of Serene as she could. Serene screamed as Cierra could feel the girl's cock actually enter her throat. The scarlet witch gagged and Serene lustfully bucked her hips in response. Cierra's lips travelled up Serene's shaft again, feeling much more comfortable with the girl's cock simply in her mouth, where she could easily play with it with her tongue.

The hand holding Cierra's red hair tightened its grip as its owner, moaning and groaning, came ever closer to orgasm. Cierra was happily unaware of this, so when Serene suddenly bent forward and her cock came into her mouth, the scarlet witch was caught off guard. Cierra tried to swallow some of Serene's semen, before she closed her eyes and opened her mouth. Serene's cock jumped free, shooting three more strands of semen over Cierra's face.

When she judged it was all over, Cierra opened her eyes and looked up into Serene's flustered, panting face. Then she looked down at Serene's cock, slick and shiny with saliva, precum and maybe semen and still hard. Cierra felt worried that Serene's ongoing erection was a sign that she hadn't done enough, but Serene grabbing her face and pulling her up into a heated, passionate kiss quickly eradicated those doubts.

After perhaps a minute, Serene broke the kiss and looked as though she was about to say something. Instead she leaned forward and her tongue came out to lick Cierra's face clean of her semen. Cierra giggled. Serene's tongue felt weirdly ticklish in a nice, but weird, way.

"There," said Serene and looked at Cierra again.

The Arc leaned forward and their lips met again. As Cierra kissed Serene, an impish thought and an undeniable urge form in Cierra's mind. Serene was still nice and hard, so maybe...

Cierra's lips left Serene's. The scarlet witch leaned away so that Serene could clearly see how she grasped the top hem of her sleeveless red dress and pulled it down until her breasts flopped out gracelessly, but definitely. Cierra leaned back further until she was lying on her back, looking up at Serene. The Arc left her chair and stradled Cierra so that her cock lay neatly in the valley between the witch's breasts.

Cierra pushed her breasts together, wrapping Serene's cock in their soft flesh. She experimentally moved them over Serene's shaft and found that the sensation of her breasts stroking Serene's cock was... very enjoyable. Maybe not as nice as when she played with them when she masturbated, but definitely... enjoyable. Cierra experimented a bit, sometimes moving both her breasts together, sometimes counter to each other. In the end she settled for having her breasts go back and forth across Serene's cock at the same time because it was easier. And she needed it to be easier, because her enjoyment was growing quickly.

Cierra gasped when Serene started to pick a pace, thrusting her cock between her breasts. It was absurd how much pleasure she was gaining from Serene fucking her breasts. Serene loomed over Cierra, placing her hands next to the witch's head and began humping her breasts faster and faster until Cierra could do nothing but keep them pushed against Serene's cock. Cierra's gasps mingled with Serene's moans as they felt each other's heated flesh.

Serene closed her eyes and gritted her teeth and Cierra felt the Arc was getting close. She also felt that as filled as pleasure as she was, she herself wasn't even close to coming. And she didn't care. Cierra wanted to see Serene's cock burst forth from between her breasts, spilling its seed over her body. She didn't have to wait long. Serene grunted and with one last thrust she came, semen landing on Cierra's chin, neck and breasts.

The Arc lay down next to Cierra and gave her a tired kiss. When they broke free and looked at each other they were both smiling affectionately.

"You're a mess," Serene panted. "Again."

"And how is that my fault?" Cierra teased back.

Serene smiled and kissed Cierra again quickly. "We should get you cleaned up. A good bath in the Undine Springs will be good for you."

"With Fia?" Cierra said.

Serene grinned. "Maybe."

Panting, both struggling to get their breaths back under control, the girls lay and looked at each other. Cierra reached out and brushed away a strand of Serene's hair that wasn't actually out of place.

"Hey, Cierra..."

"Mmm?"

"That 'solution' I asked about?"

"Yes?"

"I don't think we need to bother."
