Lyra finally meets that human she wanted to meet, but... gets a little more than she bargained for.

Because sometimes our dreams are what drive us. Sometimes the thing that keeps us going can turn out to be the most important thing in our lives, and sometimes it can redefine them at its whims. Sometimes, running after the impossoble produces results, but sometimes those results aren't at all what we expected, or maybe even wanted.

In other words, Lyra finally meets her human and discovers exactly why she always felt such an attraction to their mythology. She'll never be the same again.

Part of a story trade with darf.

Chapter 1

Good Girl

"Where is he?!" Lyra shouted, running through Ponyville's town square. She'd been hearing rumours all day, but brushed them off as ponies making fun of her until Pinkie Pie confirmed them: There was a human in town.

A real life human! No more would ponies point and laugh, telling her "it's just a myth" as if that made her feelings any less real. No more would they avoid her, or pretend they weren't home when she wanted to talk. No, now was Lyra's time to prove everything she was saying was correct.

Equestria had many myths and legends, but only one was so coherent and compelling—the legend of America, and Humanity. It was said that a long long time ago, in a kingdom far far away lived a species of intelligent monkeys that somehow managed to master something called "technology"—a clear allusion to primitive magic—and become masters of their own domain long before equinekind had even discovered language.

The mythology was long and twisted, but Lyra had read it all, even the modern day retellings written by her fellow 'Menthusiasts'. Some of the stories excited her more than others—theories on their culture, language, music, and history were fascinating, and Lyra had spent many a late night trying to piece together a canonical timeline for various tales.

Other stories appealed to her baser desires. A minor footnote in one myth suggested that humanity lacked any kind of fertility cycle, and thus they were always aroused and ready for action. Lyra had read many modern-day explorations of this concept. She'd even written one, which had received good feedback from the most local enthusiast group over in Manehatten. She didn't dare show it to any of her friends lest they point out the similarities between the protagonist, Harpa, and herself. They were purely accidental, she swore.

"Rainbow Dash!" Lyra yelled as soon as the weatherpony came into view. She spent all day flying and would thus have seen any unusual visitors. "Where is he?!"

"Huh? Who?"

"The human!"

"Oh, he left a few hours ago. Went that way-" Rainbow Dash pointed off into the distance- "and said he probably wouldn't be coming back, why?"

"Aagh!"

Fifteen minutes later, Lyra was at a full gallop heading along the path Rainbow Dash had pointed her to. She'd darted back home to grab her Emergency Human Acquisition Kit and started on her quest. The legends said that ancient humans used to ride ancient ponies because ponies were both faster and took longer to tire—Lyra hoped that that still rang true, and that she could still catch up to him.

Inside her kit were her favourite myths as well as a few more personal items that she'd gathered on the off-chance she ever got the chance to meet a human. She also had a notebook so that she could record everything, so that even if her trip was ultimately a failure she would have more information to ensure subsequent trips met with success.

Eventually, Lyra spotted a pillar of smoke rising up into the sky. A sure sign of inefficient human "technology"! Lyra's gallop was re-enthused by the sight, and she sped onwards heading right for it.

As she neared the rising smoke, Lyra decided to act with a little stealth, and started to sneak. She took care to move silently and stick close to the ground—humans were violent and aggressive creatures when provoked, and she wanted to make sure she didn't either scare or anger this one.

As she neared the clearing where the fire must be burning, Lyra heard a twig snap somewhere behind her. She turned around, but it was too late. The ground itself rose up around her as the human-trap was sprung, and a vast net entombed her.

Lyra hung there in a daze, tangled in a silken net swinging from the branch of a tree. She was entirely upside down, and the plant the net had been spun from seemed to act as a magical dampener. She hadn't seen the trap coming at all. Wasn't humanity amazing?

"Hello? I mean you no harm!" Lyra called, hoping that the human was still here and hadn't simply left his traps behind. "Anypo- Anybody?"

After a few moments, the silence was broken by a low grunt. Something looking very much like one of the illustrations in Lyra's book slowly walked into her vision.

"Oh my gosh you're real," Lyra squealed, wiggling her hooves, "I have so much I want to ask you and talk about and-" Lyra suddenly stopped talking as she realised she might scare the creature away. It looked hesitant to approach, as if Lyra might wish it harm.

"Oh, no! I'm friendly!" Lyra insisted. "Friendly pony, we're all friendly! Me especially! I've read so much about you, please could you let me down?"

The human seemed to accept that, and nodded slowly. He pulled some kind of knife from his belt and cut the net down with one sweep. Lyra cooed in amazement as she tumbled to the ground and landed at the human's feet.

Immediately, he stowed his knife away and grabbed Lyra under her forelegs, lifting her up and inspecting her.

"Uh, hi! Yes! Hello, my name is Lyra Heartstrings! What's your name?"

The human grunted to shush her and continued his inspection. After a few moments he nodded and set Lyra back down on the ground. "Sit," he commanded, and walked over to what appeared to be a makeshift camp. He leaned down and put his hand—his amazing human hand—inside inside his saddlebag and pulled something out, before returning.

"I'm Jack, Lyra. Nice to meet you."

"Oh gosh, I have so many questions!" Lyra started, trying to ignore the growing feeling in the pit of her stomach. What was it? Dread? No, that felt darker. Something else. Some intense longing or desire, unlike anything she'd ever felt. It had started the instant the human—Jack—had given her a command, like it was some ancient reaction left over from her ancestors.

"C- Can I... Can I see your hands?" Lyra squeaked. That wasn't right, she'd meant to ask about their culture and music! Was it true their primary source of entertainment was known as 'The Beetles' and they'd bred that particular species of insect for its novelty value?

"Sure thing," Jack agreed, raising his hand. In it was the thing he had taken from his backpack. It was vaguely cuboid, about two centimetres down each edge, and was white and grainy.

"What's that?" Lyra asked, tilting her head.

"Sssh, just try it."

Lyra leant forward and gave it a lick. It tasted nice, sweet. Like a cube made out of sugar. Human ingenuity! Lyra shuffled a little closer and started to nibble, breaking chunks off in her mouth and savouring them. Every time she went back for more, her lips brushed against his hand and sent shivers through her body. She needed that hand inside of he- What was she doing? Lyra was a legitimate researcher, not one of those myth-fans who was only in it for personal gratification!

But those hands...

"It's called a 'Sugarcube', Lyra," Jack explained. His other hand raised to Lyra's mane and slowly began to stroke through it. Lyra's inner turmoil visibly reduced as the rhythmic petting relaxed her and made her feel calm and safe.

"Mmm, I've heard of these! Interestingly, we still use the term even though nopony has actually been able to build one for genera-"

"Sssh, just enjoy it."

Lyra went back to slowly running her tongue over the sweet surface. There wasn't much of it left now and each lick gave her less and less of a buzz. Maybe there was still some left on his fingers? Lyra tried licking them, too. They were salty rather than sweet, but it tasted nice and Lyra continued. Her tongue found its way along the slightly wrinkled skin and into all the nooks and crannies in-between each finger. When she'd finished one side of the hand, she hopefully nuzzled Jack's fingertips until he flipped his hand over and allowed her to continue exploring.

"You liked that, didn't you, Lyra?" Jack whispered, still petting her mane and holding his hand out for a friendly lick.

"Yes," Lyra responded, pulling back and nodding. She'd explored Jack's hand completely and now it only tasted like her own saliva. Maybe she'd be able to try again some other time.

"Good girl. Now, what did you want to ask me?"

Will you put your hands inside of me? Lyra immediately thought. No, that was wrong. Not right. Wrong. Wrong wrong wrong. Lyra shook her head and tried to clear her thoughts. "Oh, uh I just wanted to talk to you for a while if that's okay?"

"Sure."

Lyra wondered why Jack was having such an effect on her. She tried her best to take a rational approach to all her human-studies, and though she had read a fair amount of what some of her fellow enthusiasts had fondly named "fapfiction"—after the noise humans could potentially make while self-pleasuring—she never considered that more important than the advancement of knowledge.

Yet, the creature that sat before her was stunning. His body was clearly muscular and athletic, and he had lifted Lyra from the ground almost effortlessly. He was gorgeous.

And those hands! They'd flexed around her tongue as she licked, and the way they'd gripped that sugarcube so securely sent shivers down Lyra's spine. They were amazing, and Lyra's hooves suddenly felt so very imprecise.

"Lyra?" Jack asked. "Are you okay?"

"I..." Lyra stammered, starting to blush. "I'm just a little distracted by uh... can you put a shirt on?"

Jack laughed. "I've never met a pony that said that to me before! I think I have one in my pack, one moment."

"W- Wait! No! Please, don't," Lyra exclaimed as he stood up. "I uh, it's okay. Can... can I touch it?"

"Go ahead."

Lyra awkwardly moved forward and brought her nose to the human's chest. Slowly, she ran her cheek over it, savouring the sensation of his hard body brushing over her coat. The deep longing from before was back with a vengeance, and Lyra was beginning to wonder why she was bothering to resist.

Jack's hand raised behind her head and began to slowly scratch behind her ear. Lyra gasped as the itching echoed through her head, driving away her fears and calming her worries. A few moments later, Jack stopped.

"No, please... keep going?" Lyra gasped.

"I'm sorry, Lyra, but I really must be moving on. I'm a traveller, y'see, so I've gotta... travel."

"Please!"

"I'm sorry, but without anybody to help carry my stuff, I need to set off now to reach the next good camping spot by nightfall."

"I'll help! I can carry things!"

"I can't go trusting you with that, now can I? I've only just met you."

Lyra's ears fell and her head dropped.

"But you are a cutie, aren't you?" Jack said, smiling as he raised his hand to her chin and pulled her head back up. "And you seem to have a question right on the end of your tongue. What is it?"

Lyra had many questions. She opened her mouth and let one free. "Is it true you humans are always aroused?"

Lyra blushed as she realised what she'd just said, and tried to hide her face. Jack burst out laughing at the accusation.

"No, no, that's just a myth. It takes something to set us off, just like you."

"Are... are you aroused now?" Lyra squeaked. She didn't know what'd come over her. Her one chance to meet a human and suddenly her mind turns off and her body takes over. All the stories she'd read had made them seem really nice, though. Much better than pony lovers, certainly. Maybe this could be research as well. Yes, that was it! Lyra had to do this, it was her destiny.

"A little," Jack admitted. "It's not every day a cute pony like yourself throws herself at me, unfortunately."

Cute! He'd called her cute! Lyra gathered all the bravery she had into one sentence, and let if fly. "Can you put your hands inside of me please?"

Jack raised a few fingers up to Lyra's mouth and held them in front of her, tempting her into licking them. She began immediately. "See, Lyra, the thing is... where I come from, ponies don't walk around freely like you do here. They're pets, or livestock. Reason that is, see, is because all those thousands of years back when our species lived together, we bred you all to obey. Now, okay, you've diverged a little from that and gotten all colourful, but some of you still got the right genes. Ain't that so, Lyra?"

Lyra nodded enthusiastically and nuzzled the fingers in the hope of more. Jack smiled and turned his hand over. Lyra wasn't really listening to his monologue, but he continued. "Now, there's a reason I'm travelling all over your fair lands, and it looks like I might just have found what I was looking for. Right, Lyra?"

"Sure yeah, whatever."

"Yeah, I think I've found what I'm looking for. Say please."

Lyra stepped back a few paces and sat on the ground. She raised her forehooves up to her face and pressed them together as if in prayer—yet another mannerism ponies had simply carried forward from their ancient human heritage. "Please? I've never felt this way before, I need you... please?"

"Yes, good girl," Jack soothed, holding out his hand and cupping Lyra's cheek. "Just stay calm, and everything will be okay."

Lyra whinnied as her instincts began to take over. He just kept talking and talking while every cell in her body screamed for his touch. She needed it, and soon. "Please?"

Jack held his finger out and swirled it around, indicating that Lyra should turn. She complied without question and stood facing away from him. Lyra's tail was already lifting faster than she'd ever experienced, and it quickly began to tickle the back of her head. She was completely exposed, but she felt no embarrassment; Only anticipation.

Jack's hand reached out and grabbed the base of Lyra's tail, before pulling her closer to him. She stumbled backwards as she struggled to regain her footing, and ultimately managed and came to a stop resting a foot or so away, well within Jack's reaching distance.

Jack reached out with his other hand and gave the side of Lyra's body a sharp slap. The sound echoed throughout the clearing for a few seconds before it dissipated off into the air. Lyra gasped in pain as the sensation resounded through her body, and Jack's hand began to squeeze, exploring her muscles and skin. The other hand still grasped her tail in a strong grip, keeping her in place while he poked and prodded around.

Lyra sensed she should stay quiet while he did whatever he was doing, and elected to simply stand there being docile. After a few moments, Jack stopped and seemed satisfied. "Yes, I think you'll do. You behaved well, too. You deserve a reward."

Lyra grinned. This was the bit she'd been waiting for. Her body tensed as Jack's fingertip brushed against the side of her rear and slowly trailed over to her thin slit. She was ready—she'd been ready for quite some time—and she was looking forward to feeling every bit of it. Jack's finger slowly made its way down the side of Lyra's folds, sending a jolt of anticipation through her form every inch it moved.

"Please please please," Lyra whispered as she felt the finger linger just a moment too long at the very bottom of her vagina, pressing into her skin with just enough force to remind her it was there and keep her mind concentrating on it. The fingers moved to the side just a little and began to rise up, slowly parting her lips as they went. Their ascent was eased by the copious fluids almost pouring from Lyra's body, and every second they were in motion drove her even wilder than before.

Soon, Lyra allowed her head to drop as she felt the sensations begin to overwhelm her sensibilities. Simply feeling the tips of his fingers rubbing against her felt magical and Lyra never wanted it to end. Over and over they trailed up and down, slowly teasing her and building up the pressure in her body until she felt like she was ready to burst, and the slightest prick anywhere on her body would have her laid out on the ground.

"Shall we go a little deeper?" Jack asked, pushing his forefinger half a centimetre further in, before pulling back out. He continued to stroke against the surface, awaiting her answer.

"Yes!"

"That's not very polite, is it? Say please."

"Yes please!" Lyra called, lightly pushing her hind back onto his hand. Jack seemed satisfied with her request, and began to slowly insert one of his fingers inside of her. Lyra whinnied as she felt the thin digit intrude into her body, its path easily lubricated by her own juices. Her mind whited out in pleasure for an instant as the finger began to swivel around, scraping against her inner walls and sending bolts of sheer joy all throughout her form.

Even more slowly, the finger began to retreat. Lyra felt empty as it left her, but was quickly sated as it began to return. It felt around inside of her in little circles as Jack explored her insides and filled them with more pleasure than Lyra could possibly have hoped for—she'd heard that replica human hands felt great, but nothing could compare to this. Nothing.

"More?" Jack whispered, teasing with a second finger. Lyra couldn't think of anything better, and immediately whinnied in approval while bucking back as far as she could go. Jack's other hand still held her rear firmly in place, so she couldn't go far. "Now now, be polite," he cooed, retrieving his finger and leaving Lyra with only the one.

"Please?"

"Good girl." Jack returned the second extremity and slowly worked the two fingers a little deeper between Lyra's lips. Lyra gave them an encouraging squeeze and brayed in delight as Jack began to more quickly pump them in and out of her, quickly filling her mind with a torrent of pleasure. Her forelegs gave in and she fell to her knees, resting her head against the ground as she let his fingers quickly slide around inside of her, bringing her closer and closer to bliss each time.

Lyra felt her worldview start to shrink as her eyes fluttered closed. All that mattered was her, the fingers, and the person the fingers were connected to. Nothing else. Her head didn't contain a single thought for her home, or research, or any of the reasons she'd originally travelled so far to see one so strange. All that mattered now was-

Lyra's hindlegs gave in, and her entire weight was suddenly taken by her tail as Jack kept his grip and held her up. The pain shot through her, but was quickly overtaken by yet another wave of pleasure as his fingers slammed into her yet another time.

"More?" Jack whispered, pulling his fingers out and adjusting his hand so that a third finger could tease around her anus. It was smothered in her own fluids, and was more than lubricated enough to slip a little inside. Lyra hadn't ever considered that hole a valid target, but something about the way Jack's finger slowly drew circles around it sent shivers down Lyra's spine.

"Yes, yes please!" she begged.

"Not good enough. Call me sir."

"Yes, please sir. Please." Lyra immediately complied.

"Yes, good girl. Good girl," Jack whispered, praising her on her good behaviour. He slowly pushed his hand forward, skewering Lyra through two holes and driving a stake of sensation through her brain. She'd never thought that her "tail hole" could be much fun, but Jack's finger penetrating deep inside of her was quickly proving her wrong.

His hand quickly began to pump, pushing into her body with enough force to send her skin rippling and blast a wave of pleasure through her entire body. She felt her hooves begin to tingle as the pleasure began to become overwhelming, and her mind started to shut down in anticipation of her release. Her inner walls began to reflextively contract around the two fingers as her body took control, and Jack could tell she was on the precipice of orgasm.

His fingers slowed down. He kept them moving just fast enough to keep Lyra on the edge, but just slow enough that she wouldn't tip over. The blinding pleasure was almost agonising. Lyra's mouth fell open as she began to drool, and her eyes rolled up into the back of her head as her higher brain function began to slow and abandon itself to unparalleled joy.

"Lyra," Jack whispered, yanking on her tail a little and rousing her from her half-slumber. "Lyra?"

"Mmm-hm?" Lyra moaned, not trusting herself to speak.

"You want to finish, don't you?"

"Mmm."

"How about we make a deal, little pony? You know what I was saying about ponies where I come from being livestock, or pets? How about it?"

Lyra happily nodded against the soft dirt, smiling softly as she basked in the pleasure.

"Good girl." Jack's fingers increased in both frequency and force, and Lyra was quickly taken over the edge. She screamed out into the distance as her body writhed around and she was dropped to the ground as Jack released her. The dirt beneath her was wet and muddied at both ends of her body, but she didn't seem to either notice or care. All that mattered now was that she was happy.

Jack wiped his fingers against her coat and stood up to examine her. She lay dormant on the ground, breathing heavily and still shivering slightly, and she was still smiling while she stared off into the distance without comprehending a thing.

It was true, Jack was a traveller, but he'd been travelling in search of one thing in particular. A modern-day pony that still embodied the ancient genes that had been bred into their species so thoroughly that even now, hundreds of generations later, the average pony was noticeably more docile and relaxed around humans. The effects had been diluted by tens, or maybe even hundreds of thousands of years of breeding outside of human control, except for in a very few cases where their bloodline just happened to be almost completely pure right back to the very beginning. Lyra was one of these ponies, and the effect was obvious.

No matter why she really approached Jack, after barely a few minutes in his presence she was already more than happy to be as subservient as their species had been bred to be. Mixed, apparently, with a little additional sexuality. Jack had been expecting a pony that would nuzzle his side and offer to carry his bags, not one that would happily bend over. He didn't mind.

Regardless, genetics wasn't everything. Lyra would still require training, but at least she was receptive to it. Jack supposed he might as well start as soon as she recovered.

"Lyra, you awake yet?" Jack impatiently asked an hour or so later.

Lyra stirred and rolled over to look at him. Immediately her eyes lit up and she jumped to her hooves. "Yeah, I'm awake! Oh, gosh, you don't know how great it is to finally meet one of you-"

"Silence. Sit."

Lyra shut her mouth and found herself resting back against her rear before she had time for a second thought. She couldn't place it, but she knew it felt right to do what she was asked. Jack smiled and turned back to his saddlebag to retrieve something.

"Come here," he commanded after a few moments of rummaging. "Hold still for a moment."

Jack pulled out a few pieces of a bridle from his back. He had a saddle—not that Lyra was large enough to ride—and a harness for a pony's head. Lyra stayed silent and held still while he strapped her in, pulling the coarse material straps tight to ensure she was properly held. The head harness had an adjustable bit that could be swung both in and out of her mouth as required. Jack opened her jaw with two fingers and screwed the bit in tight, before letting her mouth close as far as it would go.

After that, he turned back to his bag and pulled out a basic set of reigns, which he attached to small metal rings on the harness. Lyra was now completely strapped in, and Jack tested the contraption with a few quick tugs on the harness to steer her left and right. She quickly got the idea and trotted around in front of him at his commands.

"Good, you learn quickly, my little pony."

Lyra blushed a little at the unexpected compliment. It felt nice. All that mattered was it feeling nice.

"I'm afraid I don't have a nametag for you yet, I can get one made once we're back home. Would you like that, Lyra?"

Lyra nodded and gave an approving grunt through her bit. She would have spoken, but that was impossible.

"Excellent. Say, you seem to be recovered now, so how about we break you in properly?" Jack suggested, yanking her rope to bring her closer. He dropped down to his knees and ran a finger down Lyra's slit once more. Her tail quickly began to rise—he had a small bind that could pull it out of the way if necessary, but Lyra seemed to do a good enough job of that on her own—and allowed him entry. Lyra whinnied in approval.

"Actually, we shouldn't. Let's just get going," Jack decided, standing back up and tugging her along. Lyra whinnied again, this time in annoyance and desperation.

"Pfse!" she said—or tried to—and tugged at Jack's trousers. Jack smiled and turned back around. He knelt once more and quickly undid the bit, swinging it away from her mouth and granting her speech once more.

"Please, sir? Can we please?" she begged, before again tugging at his belt and trying to pull it down.

"You want this?"

"More than anything, please!"

Jack seemed to accept that, and motioned for her to spin around once more. He quickly unbuttoned his pants and pulled them off, dropping them to the side and leaving them in an untidy pile. His penis flopped out, quickly hardening as it realised how soon it was to be used. Lyra dropped to her foreknees and braced against the ground as she began to fantasise and lose herself to the anticipation, and Jack grabbed her reigns once more. It was time to take his little pony out for a ride.

Aligning himself with his spare hand, Jack pressed the head of his shaft against Lyra's still-wet lips and left it there for a few seconds while the shivers of anticipation rocked through Lyra's body. After a moment, he slowly pushed forward. Centimetre by centimetre, Lyra felt herself become filled, like a vast hole was being completed in her body and she'd never even realised it was missing. Every second he continued thrusting, she felt more and more complete.

Her head rested against the ground as she pushed back, ensuring his journey was as painless as possible. Her mind concentrated on nothing other than the way he was skewering her rear, enjoying every tiny little slip and the tiniest motion as his shaft shifted around inside of her, moving slightly with each heartbeat and tilting as he repositioned himself to get a better angle.

Jack's spare hand slapped down onto the side of Lyra's flank, and his riding hand tugged her lead to the side, causing Lyra to whinny out in protest and instinctively lean in the direction she was pulled. Jack seemed pleased and quickly pushed himself the rest of the way in, slamming against her body with a sudden force. Lyra braced herself against the ground and pushed back to make sure she could stay in position.

Jack slowly began to pull out, leaving Lyra with the feeling of emptiness once more. Her boiling hot inner walls lightly contracted against his length in a vain attempt to keep him inside as he left her, but it was no use—he was gone.

"What are you, Lyra?"

"A pony, sir!"

"Whose pony?" he asked, bringing his hand back down on her ass and letting the sound echo around once again.

"Agh! Your pony, sir! Yours!" Lyra gasped, splitting her attention between the cockhead still resting against her and the commands of her new master. "Please, sir!"

Jack accepted it, and pushed in again. His length was quickly hilted once more, and he began to slowly and rhythmically stroke in and out, resting his hands against Lyra's rear for a better grip and more control. Lyra began to gasp and groan as she felt him enter and leave her over and over again, and she found herself unable to think about anything else. Nothing at all.

"You're not just a pony now," Jack grunted, punctuating each word with a thrust, "You're my little pony, you slut."

Lyra simply braced there, eagerly accepting his rod every time it was offered. Her mouth hung open and a little gasp or groan escaped from it at the apex of each stroke, and she found it very difficult to care about anything else.

"Isn't that right, Lyra?" Jack prompted.

"Yes, yes sir!" Lyra gasped.

"Good- Good girl," Jack praised, gritting his teeth as his own strokes combined with Lyra's continued light contractions to bring him closer and closer to the edge. Lyra couldn't be far either, her body was twitching and spasming at his touch and she almost certainly wouldn't last much longer. Jack's thrusting grew more erratic as he neared the peak of his pleasure, and he knew he couldn't last much longer.

His hands squeezed tight and grasped Lyra as tightly as he could as his hips reflexively pushed forward, and he buried himself as deeply as he could. Lyra's fleshy walls continued to contract around him, milking him dry as he let off load after load of his sticky man-cum directly into her. Lyra felt the heat spread throughout her body as her insides became coated and her mind finally turned off, letting her bask completely in pleasure as her ancient instincts kicked in and gave her all the reward she could ever want. Humans and ponies were biologically incompatible, but nobody told her body that, and it wanted to reward breeding as best it could.

Jack slowly pulled out and tried to stand. His legs were much weaker than he'd been expecting—he'd heard that ponies had gotten better through the past couple of millennia of evolution, but...

He fell back to his knees and decided it was probably best to just lie down and take a quick nap. Lyra was already asleep, there was no shame in joining her. Jack stretched his arm over Lyra's body and held her tight as he drifted off into slumber. The force of it woke Lyra for just long enough to allow her to roll over and snuggle against his chest.

"I love you, sir," she whispered.

"I know."
