Hidden Depths (Flayn/Byleth from Fire Emblem: Three Houses)

Byleth knew there was going to be a degree of danger and uncertainty regarding what they were doing. He had signed up to it anyway, for any hurdle was worth satisfying his curiosity. Nevertheless, he never pictured things would escalate in such a dramatic fashion.

Flayn was an adventurous young girl. He was drawn to her as soon as they met. There was always a playful yet mysterious aura to her, and that bizarre combination was something he found himself drawn to. She, too, found herself strangely allured by him, and thus, a secret relationship between the two inevitably blossomed.

The only reason it was a secret was that they wanted to enjoy the privacy of their little relationship first.

But when things started to grow especially bold and risky, the secrecy remained indefinitely… and it certainly didn’t help that the risk was surprisingly fun.

It all started simply enough. The two met in secret and got to know each other better… but a physical attraction was very prominent. Both individuals were insanely curious about the other, both sharing a history of being fairly sheltered from the outside world. Hugging transitioned into kissing, and kissing transitioned to full-on making out! This happened within weeks, and while it was fun being in this stage, they quickly found themselves climbing to the next level. After all, they hadn’t been spotted at all so far, so why not enjoy even more risky activities?

Flayn especially liked to be risky. Fueled by a sexual appetite that eclipsed his, she’d often drag him to a private location, only so she could fall to her knees and suck him off. If the monastery wasn’t too active, they’d fuck right there and then too. She wasn’t a particularly patient one when it came to their sex life either, leading to some locations being less than ideal regarding privacy… but the thrill of being caught was something neither could deny the appeal of.

Byleth fondly recalled a moment several months into their relationship where she decided to pull up her dress and flash him when there were others nearby! She had purposefully worn very little underneath as well, making sure he got to see a lot of her delicious body. Because of that one naughty move, that day in particular had turned into a very special one.

…and that was just scratching the surface of the things they had done!

One would think Flayn wasn’t a particularly developed girl, but that was only due to how baggy her usual Garreg Mach attire was. It was handcrafted by Seteth, making her look all cute and innocent. Byleth knew that he likely made her wear it on purpose; if more knew about how much of a voluptuous body she really had, they would pay way more attention to her, and he certainly didn’t want that.

Byleth wasn’t sure whether to find amusement or guilt in the fact that Seteth truly had no idea about what he was doing to precious daughter. Flayn had already told Byleth the truth of their relationship, rationalizing a bit of the man’s overprotectiveness, but he believed Seteth was being far too restrictive. He vowed to tell the man the truth one day, hopefully receiving the man’s blessing in return. After all, the relationship he had with Seteth’s daughter wasn’t one of mere lust… there was love there. Lots of love, in fact! Sure, physical attraction may have had a significant role to play in its birth, but by this point, he knew he was in love with Flayn.

She did too. She wouldn’t have told him her secret otherwise, nor comforted him with lots of cuddles whenever he had a stressful day. Their sex life was certainly wild, but they cared deeply for one another.

Unfortunately, it was going to be difficult to tell Seteth the truth any time soon.

Something had happened that they were not accounting for.

Flayn was kidnapped.

Well, that was the public story. It wasn't one they had planned, however. In hindsight, they should have prepared for the possibility of pregnancy considering how often they met up in secret to engage in heretic acts… but there was no time for regrets now.

...and neither really saw Flayn's unplanned condition to be something they'd have to worry about; her baggy clothes would hide her growing belly well!

Unfortunately, it had become a little too noticeable for comfort. Thus, Byleth decided it was best to hide Flayn away for a while. Flayn had written in a letter in advance justifying her momentary absence.

It all sounded like a good plan on paper. The excitement behind having a baby had mitigated any belief that this plan would see any protest.

Seteth interpreted Flayn's letter as evidence she had been kidnapped. She had worded it in a way that suggested some unknown man had whisked her off her feet and promised a better future for her. It wasn't entirely untrue, but to someone so overprotective who lacked context, it appeared Flayn had essentially been manipulated into leaving with a dangerous man.

As a result, news of Flayn's unprecedented elope spread like wildfire, all while the pregnant girl was safely tucked away in Byleth's bedroom. Naturally, no one suspected the professor of any foul play, but an immense amount of guilt was being experienced regardless.

"You are too stressed," Flayn commented while he was lost in thought. "Just relax, okay?"

How could he relax? Seteth deserved to know the truth, but he wasn't sure if the truth was actually any better! It was… it was…

He had tried his best to ignore it, but she was doing such a wonderful job.

Despite everything, Flayn's sexual appetite had not dwindled. If anything, it had escalated! She had it bad!

While the monastery was presently searching tirelessly for the missing girl, the girl in question was currently giving her favorite man a blowjob. Sure, scaring her father wasn't something she was proud of, but it was so easy to forget about that while she was slobbering on a cock. He had lost count over the number of times she had kissed and licked his shaft by this time. It was probably in the hundreds by this point… and she had only been doing this for about a minute!

“Mmm… you taste so good…” Flayn giggled so unstably, never one to shy away from losing herself a little to lust. “Does it feel good, my dear? Just sit back and relax-- let me make you feel good, and let all those worries melt away.”

Flayn was offering genuinely good advice. There was no point worrying so much about the future when they were in the present. He watched as she tended to his member, sometimes doing so elegantly, but other times doing so wildly.

He found his mind drifting towards the past-- back to the first time she had done such a thing for him. It was hard to believe she was ever nervous about giving head before!

___

“...Professor, I have a request…”

Flayn had come to him while he was fishing one day. At first, he assumed she wanted to fish with him and was being a little shy about it. This was back when she hadn’t discovered her love for risk-taking just yet, but this absolutely the day that kickstarted her adoration for it.

“How can I help you, Flayn?” he asked, a little concerned. When he got a better look at her expression and saw how red in the face she was, he had a hunch as to what she was going to ask for.

More cuddles? More kisses?

Back during these early months, that was the norm.

But Flayn had decided on this day that she wanted to escalate things quite dramatically.

She sat down beside him, watching him fish. She shuffled a little closer when no one was looking (and after she had gathered her confidence) and breathed heavily into his ear.

“I want to suck your cock…”

The pure shock of hearing such an innocent voice say something so lewd distracted Byleth enough that a fish got away, but for once, he didn’t care about letting one go.

He was aware they had gotten a little carried away before; a sensational kiss had escalated into one of pure passion when tongues started to intertwine… but this was quite the jump in intensity!

“...Flayn, I’m…” he had no idea how to respond! If he was capable of expressing emotions better, he would undoubtedly look a little flustered. Despite how rarely his face changed, Flayn could detect the nervousness in her voice, making her giggle. “...we’re at the fishing pond. This isn’t a good location.”

“...it will be okay!” she reassured him. “Not many people are around this time of day… so you can keep fishing while I get to work…”

Flayn wanted to do that… here?!

He assumed they would return to his room, or at the very least, they’d sneak off somewhere notably private.

The fishing pond was not a private place.

How would he even be able to focus on fishing while she was…?

But still…

The thought of her putting his cock inside her mouth… and sucking on it…

It felt wrong! She looked so utterly adorable that allowing her to do such things would be akin to defiling her.

…but then again, he supposed he was far past that point already. He had seen how lewd she looked after an intense snogging session, and while he hadn’t seen her body yet, he had copped a feel of her surprisingly large breasts; they weren’t quite as bountiful as ladies like Manuela, but for someone so short, they were impressive! In other words, Flayn was deceptively innocent. He knew far better at this point, so why resist?

The more he thought about it, the more he decided this was a good idea, even if a voice in his mind was also scolding him for doing something so insanely reckless.

Regardless, he was sold. A cute girl offering to suck him off? How could he say no?

And honestly, she did have a point! He had been here for about an hour now, and only saw a few people walk by. The sun was setting and pretty much all the students had returned to their dorms. Maybe it wasn’t as risky as he thought…

“...fine,” he gave in. “But… if things get too risky, we’ll return to my room, okay?”

He still wanted to play things safe in a way that wouldn’t deny his dick the warmth of her mouth.

“Y-Yes… of course…” she was thrilled at his positive answer, as if she had been contemplating making this request all day. Knowing her, she probably had! Flayn got to work admittedly, working on undoing the parts of his outfit that separated her from her prize. It took some time, but she eventually fished out his cock… and she admittedly flinched. “Ah… y-you’re so big…!”

She had felt his erection before so was aware he was fairly sized, but she had never seen his cock in the flesh.

…and now, she was salivating.

Byleth hadn’t decided yet if it was a blessing or a curse that he got to see this hidden side. While he was undeniably benefitting from it… he feared their continued shenanigans may result in someone finding out…

“You don’t have to do it if you don’t-”

…he was intending to give her an ultimatum just in case she wanted to reconsider, but as if knowing what he was about to say, she immediately silenced him by leaning in and kissing the tip.

He shivered at the sensation. One simple kiss had done that!

Fueled by his reaction, Flayn returned her hand to his shaft, stroking it slowly as she experimented with how it felt and how he reacted.

“Oooh… am I making it twitch like that…?” she giggled, sounding so innocent still, but her actions were far from it. “It’s kinda cute, professor…”

“...Flayn, you’re driving me crazy here…” he was honest. He could not stop thinking about that kiss! He wanted to feel that shiver again… and to think-- she hadn’t even put it into her mouth yet! He had only received the equivalent of an appetizer and was already feeling extraordinary! “Please… don’t tease me, okay?”

“So what you’re saying is that… you want me to do this.”

Feeling her lips against his tip was an incredible feeling unlike any other… but the euphoria continued to enhance as Flayn pushed and allowed his cock to open up her lips. Once he felt her tongue and the humidity of her mouth swarm over his most sensitive part… Byleth abandoned any desire to continue to fish. The last thing he wanted was a distraction from how absurdly amazing this felt!

All Flayn had done was take the tip into her mouth, and he was already on the verge of losing it! It was breathtaking, and the fact that such a cute girl was willingly doing this for him was even better.

He quickly looked around, double-checking his surroundings for any unexpected company, and breathed a shaky sigh of relief upon seeing no one was around.

Flayn was humming non-stop, mesmerized by how it felt to have a cock inside her mouth.

As delighted as she sounded, she wasn’t content with just taking the tip inside. She wanted to keep going until the tip of her nose was touching his crotch…

Byleth was flabbergasted by how much she was able to take in. He watched her head sink slowly but consistently, but eventually, Flayn found her limit after taking about half his length in. Her gag reflex kicked in and she hastily ejected his shaft, revealing how drenched in saliva it already was.

Flayn was a little disappointed she couldn’t take more in, but this was the first time she was sucking cock. That fact alone was filling her to the brim with happiness.

She had fantasized so much about doing this kind of thing, but nerves had held her back from asking, even as things got frisky with her professor.

But today, she woke up feeling unbearably horny. Not wanting to disturb her professor’s free day, she had held back for the majority of the day, deciding she’d pay him a visit at night.

…but she couldn’t hold back for long. The thought of his huge cock deep down her throat… the thought had driven her mad! When she saw him by his lonesome at the fishing pond, she knew she couldn’t restrain herself any longer.

Flayn gazed up at his face, pleased to see he was blushing quite a bit! She rested on his leg, treating his cock to a multitude of kisses and smooches until she was ready to give it another go. Her professor said nothing, but she suspected that was because her inability to keep her lips off his cock was immobilizing him.

While it would undoubtedly be fun to continue to suck him off here… he did have a point when he mentioned it was an unorthodox location. The space here was also limited, and she could tell he wasn’t fully focused due to the fear of being caught. A change in scenery would help them both!

…and it would mean he could be really ruthless with her if he wanted to…

___

Recalling the time she first sucked him off was fun. They were so innocently adorable back then!

They had snuck off back to his room where she experimented again with how much she could take in. She was able to fit in an extra inch or two, but couldn’t go beyond that. He was happy for the change of pace, for it was ridiculously sexy to see her on her knees and between his legs, joyfully doing something so lewd…

But it was a little difficult to focus on those thoughts, nor did he really see the need to do so, especially considering Flayn currently had his entire cock submerged within the depths of her mouth. Her nose was tickling his pubic hair as she continuously sucked, and to encourage her efforts, he wrapped his legs around her head, essentially trapping her in place.

While such an action was a little cruel on paper, he knew she loved the feeling of almost suffocating on his cock. She had trained her gag reflex well and was fully capable of deepthroating him with joy nowadays, and was more than happy to do so daily! Long gone were the days where she was a novice cocksucker; his girl knew how to please him!

Another reason he had buried her head between his legs was because he wanted her to swallow his seed. Flayn had no problem doing this, but she really, really liked him cum inside her pussy instead. It had been some time since he had let it all out inside her throat, and while she’d undoubtedly complain a bit after, she wouldn’t be too fussed; she still did like the taste, after all.

Byleth couldn’t handle the intense pressure anymore. Her throat was so compact, and her mouth so warm!

“Flayn… be a good girl and swallow my cum, okay?” he warned her, encouraging her to comply through his words. This naughty girl also loved praise, so being told she was being a ‘good girl’ was music to her ears.

Flayn hummed in delight as his cum swam into her mouth. She was already feeling overwhelmed, so to feel his semen overflowing into her mouth was a true test of her skill and endurance. He wasn’t surprised to see her past the test with flying colors. She swallowed constantly without showing any signs of discomfort. Once his climax started to conclude, only then did he release the grasp he had around her, allowing her to eject his cock and finally breathe.

She understandably looked like a mess. Saliva and a little semen stained her face, and a fair amount of the latter was leaking out of her mouth. Not one to waste his tasty cum, she quickly retrieved it with a finger and dabbed it against her tongue. She sucked on her finger slowly and passionately, knowing full well he was watching her.

Once it was all gone, she released her finger with a loud pop, giggling at her favorite man right after.

“Mmm… all gone, my dear~” she spoke softly… and seductively. She opened her mouth, showing him that indeed, nothing was left. He would have believed her regardless, but something about seeing the physical proof was ridiculously hot. “Your cum tastes so good, Byleth… but next time… let it all out inside my pussy, okay?”

“That’s fine-- so long as you don’t mind ‘next time’ being now,” he suggested, making her giggle in delight.

After tasting his cum, she was desperate to feel his cum inside her. She was definitely holding back quite a bit; usually, she would have pounced on him by this point and ridden him non-stop until that warmth she adored so much was filling her up. He suspected the only thing holding her back was her pregnancy; she couldn’t be too wild at the moment, and while that was a little frustrating for her at times, it did lead to some more gentle and passionate sex. Both Byleth and Flayn had no problem with that, however! All it meant was that it would be even sweeter to return to the wild, rough sex they loved so much once she had given birth.

He still did miss it quite a bit though.

It was honestly baffling to think that gentle sex was a rarity for them! Even during their first time, their ridiculous level of arousal had led to a complete lack of elegance.

He’d never forget their first time. It was magical.

___

“Flayn, don’t do that!”

The number of risks they had taken lately was high, but this was a level of recklessness he couldn’t agree with!

They were at the point in their relationship where it was commonplace for them to sneak off so he could either eat her out, or she could suck him off.

…well, he knew that wasn’t exactly typical in a relationship, but he wasn’t complaining about it. They had a few good spots that people rarely visited, meaning the thrill of public indecency was still there, but the chances of actually getting caught were slim. That was how he liked it.

However, lifting up her dress to show him that she wasn’t wearing panties today was not something he could consider a good idea.

Well, the act itself would have been fine… if it was done in his room!

Flayn, in her infinite wisdom, had decided to flash him in the middle of the courtyard.

In other words, a very public place. People were around, and while she had only flashed him for about a second, he was now stuck in a state of simultaneous arousal and terror.

If he had a functioning heart, this girl would have given him a heart attack by this point. Her insistence on reckless play had arguably awakened more emotions from him than anything else as well!

“Did you like what you saw?” Flayn asked, ignoring his whisper-shout. “I think you did.”

“Flayn… there is a time and a place for such things… and this was neither of them,” he scolded her… somewhat; his tone of voice was betraying him. He sounded way too shocked for his speech to be taken seriously.

“So is that a ‘yes’, or a ‘no’?” she asked, finding amusement in his response. She was enjoying this a lot.

Byleth was conflicted on what to say. He didn’t want to give her the satisfaction of an answer, but at the same time, he didn’t want to give her the impression he didn’t like it. He absolutely did! Her body was gorgeous!

But the location? Awful!

“...yes, I did like it,” he answered, but continued before she could speak another word. “However… please, please don’t do something like that again-- not here, I mean. Save it for the bedroom.”

“Sure, sure,” Flayn was happy to accept. She didn’t want to scare her professor too much. “Speaking of your bedroom… I would like to visit it tonight.”

“For the usual?” he responded.

“Nope!” she chuckled, leaning a little closer so she could whisper into his ear. They were already speaking quietly, so it was only so she could make him shiver with her hot breath. “Tonight… I want you to take my virginity. I’m ready…”

It wasn’t the first time she had brought up the prospect of having sex, but Byleth had been hesitant.

Truthfully, he wasn’t really sure why. He suspected it was a nervousness about his ability to perform, as well as wanting to ensure her first time was magical. His father had once had the talk with him, and as awkward as it was with his consistently emotionless face, he did recall his father mentioning that a woman offering her first time to a man meant they were very special to them.

Sure, there was also a very real possibility that her flashing him, and the subsequent arousal he was experiencing, had a role to play in his decision… but so be it! He was just about done “hmm”ing and “ahh”ing about it anyway.

“...okay. Let’s do it,” he offered the answer she was hoping for, making her grin morph from a cheeky one into one of genuine happiness and excitement. “I want it too.”

“R-Really…?” she was a little flabbergasted. “T-That… ah… I mean… t-that’s great! Um… uh…”

Flayn wasn’t expecting him to actually agree. She wasn’t particularly fussed about him being uncertain, figuring he’d come around eventually… but she wasn’t expecting it to be this soon! She just wanted to tease him!

Now she was a little worried-- was she actually ready?!

…she was. She absolutely was. Why was she doubting herself now? She had been wishing to experience sex for so long… and these feelings had escalated after meeting her wonderful professor. What better man to lose her virginity to? She adored him.

“O-Okay!” she was feeling strangely worn out all of a sudden! “Tonight it is…! I’ll see you then, professor…!”

It was odd to see Flayn express nothing but pure excitement. It was definitely an always-present emotion, but a degree of cheekiness was typically around too.

It put a smile on his face. She was really excited, and it put to rest any doubts in his mind that she was jumping into something she wasn’t prepared for.

___

“Byleth! Byleeethhhh!!! Your cock feels so goooood!!!”

It was amusing to think back to that day. His approval had made her so adorably timid! He, unfortunately, hadn’t seen her reach quite the same level of shyness since, but there was a good reason for that.

Flayn was a natural at fucking.

It made sense. Her body and mind had been craving for it for so long.

Of course, the fact that they had sex basically daily contributed to her skill too.

Because of her pregnancy, the positions Flayn could be in were limited. Luckily for her, she loved bouncing on his cock. It was times like these that her true heritage revealed itself in the form of an astonishing level of strength. She was able to ride him without her speed diminishing at all-- not even her pregnancy was slowing her down!

It was a beautiful view too. Her breasts wouldn’t stop jiggling, and though it was hard to tell because of the sheer speed, he was pretty sure she was salivating.

He initially felt a little guilty sitting back and letting her do all the work considering her condition, but seeing her at work was a reminder that there was no need to worry.

…he just hoped her reckless speed and strength wouldn’t hurt the baby in any way, but he was certain he was just being a little paranoid.

Watching her pregnant belly reminded him again of that same day.

The day he had taken her virginity.

Why?

It was the day he had also gotten her pregnant.

They were not prepared beforehand. They wanted each other and that was it. The thought of protection hadn’t even crossed their mind. They had succumbed completely to lust.

And love.

There was nothing he would change about that night, and he amusingly did have the ability to go back and redo if he wanted to! He never considered it, however. It was too magical, field by nothing by a wonderful mix of lust and love. He wouldn’t change it for the world.

___

The level of nervousness Flayn displayed as she entered his room was reminiscent of the first few times she had paid him ‘special’ visits.

He doubted she’d remain in that state for much longer though, especially as some giddiness was beginning to shine through.

"...the last few hours have lasted for an eternity," she initiated the conversation with a nervous giggle. “It felt like they would not end.”

Byleth did not feel too worried about what they were going to do. He was committed to staying enthusiastic and determined; that way, she'd know she was safe and in capable hands as he took her virginity.

"They have," he agreed. "But let's not waste any more time, shall we? I wish to see you."

Byleth could be authoritative at times, but this was the first time he visually saw Flayn shiver at how commanding his tone was. It was likely due to his request more than anything else though; despite how much they had fooled around before, they hadn't seen each other naked before! The primary cause of that was due to their tendency to fool around in public places though. The most notable thing Byleth hadn't seen was her breasts, which he knew were deceptively large. He wanted to see them!

"...v-very well then!" Flayn was happy to agree to his request… even if her speech was a little shaky. "Allow me to show you the body you shall make love to!"

Her wording was very characteristic and super adorable to hear.

Flayn took her time stripping, but she managed to succeed in the end. Nerves weren't going to hold her back for long!

She hesitated most when it was time to take off her bra, promoting Byleth to ask something that had been on his mind.

"...do you not like your breasts?" he asked.

Flayn took a deep breath, thinking of a way to word her thoughts. "I… do like them, but… I am worried that you are the type to prefer them smaller, so…"

...that was an interesting observation to make, considering guys generally preferred them bigger.

Perhaps she was worried because the rest of her body was petite? There were exceptions, such as her bubbly butt, but she was much shorter than he was. Because of all these factors, as well as how anxious she was feeling over her first time, it was reasonable for doubts to come into play.  Right now, she was probably thinking he only liked her because of her small body, and anything that went against that, like her bigger breasts, would turn him off.

Flayn was being adorably foolish, and it was his job to set things right.

"I like breasts of any size, Flayn," he was honest with her. "Small, medium, or large-- there are benefits to them all… and regardless of their size, I'd still find yours ridiculously sexy… because… well, they're yours."

He knew the comment was a little cheesy, but it was exactly what she needed to hear to convince her all was well. After dispersing any lingering doubts, she finally stripped fully naked.

Seeing her boobs in the flesh was a beautiful sight. She had absolutely developed quite a pair. She was a lot larger than a good chunk of his female students! He found it especially exciting since her outfit hid them so well, so no one else had any idea how she was really sized. There was a lot to squeeze and play with if he so desired it… but that would come in time; they were here to do something else first!

Byleth soon joined her in the nude, amused by how very blatantly she was staring at his chest.

“...so, uh, how do you want to do this…?” Byleth wasn’t too sure where to go from here. He hadn’t planned ahead at all.

Fortunately, Flayn did have a position in mind. “I want to be on my back.”

Her desired position was surprisingly romantic and traditional, a far cry from the things they had done in their relationship so far.

Byleth knew what he had to do as he knelt in front of her, positioning his cock close to her entrance… but the thought of initiating was making him hesitate.

He had expected her to continue being cheeky and insist on riding him or something-- he wasn’t used to her being so… submissive. It was throwing him off.

“Relax, professor,” Flayn giggled. “Just… put it in… and listen to nothing but your instincts, okay? I shall be okay. I promise.”

He had almost forgotten that when a girl had her first time, it tended to hurt!

…but this was Flayn. She could handle a bit of rough play.

Deciding he had waited long enough, he pushed his cock up against her pussy, taking a moment to find her opening. Just as he felt frustration brewing, he finally found his mark, and his cock slotted in effortlessly. It was a perfect fit.

Flayn hummed at the sensation, her voice leaking pleasure… but also a little pain. Byleth did not hesitate further-- not after seeing the look of pure determination coating her face.

“Ahh… f-finally…” Flayn sounded so relieved. He knew very well just how much she wanted this, and to see her experiencing so much satisfaction encouraged him to focus fully on the task. He wanted to make her feel even better, and he wouldn’t be able to do that if he kept thinking too much.

He recalled her advice and stuck to it. He leaned forward, using her breasts as cushions for his hands while he started to thrust. To actually feel their actual softness, no longer obstructed by the texture of clothing, was greatly arousing… but as fantastic as it was, it wasn’t as magnificent as how warm and tight her pussy was. His speed was initially slow; there was a lot to get used to on his part, and he believed Flayn needed some time to adapt before she was ready to move on.

“D-Does it feel good…?” she asked shyly, actually looking a little concerned! He was used to her asking such things with a cheeky tone, so to hear her genuinely worried he wasn’t feeling good was quite the surprise.

“It feels amazing, Flayn…” he told the truth, and his voice aided in eradicating her doubts too.

“I am glad…” she giggled, smiling at him with so much radiance… though that grin soon transitioned into a satisfied smirk. There was that cheekiness he knew and loved! “You can go faster… I can take it!”

There was no reason to doubt her. Besides, he was ready to continue too.

As he accelerated his thrusts, he relocated his hands to his hips so he could fuck her a little better. It didn’t feel as good as having his fingers sinking into her squishy breasts, but on the plus side, he was gifted with quite the view in return. His pace was now fast enough that it was causing her tits to jiggle quite a bit. Flayn was completely oblivious to the way her body was reacting; she was too focused on trying to stay sane! Her eyes were closed, her hands were tightly grabbing the bed sheets, and her moans were non-stop. As he increased his speed further, the volume of her groans increased, serving as wonderful motivation to completely and ruthlessly dominate this girl.

It was rare for him to have the authority for once. Flayn was always the one to initiate their little shenanigans, sneaking him off somewhere so she could suck him off. While had returned the favor many times, he always felt like he benefited the most from their arrangement.

But now, it felt like he was truly paying her back for all the wonderful times she had given him. Even though exhaustion was starting to make itself known, he didn’t let it stop him; his will to make their first time a magical one could not be beaten.

Flayn was losing it. Her body was shaking non-stop, expressing a level of instability he had never seen from her before. Even so, it was still subconsciously trying to maximize her pleasure. For instance, when Byleth felt her legs wrap around his back, pulling him a little closer towards her, he knew that was her way of telling him to not stop.

“Bylettthhhh… Byleeettthhhh…!!!”

…that was the first time she had called him by his actual name.

It was always professor this, professor that.

He didn't mind that, of course; everyone else referred to him by his occupation. It was just how things were.

So to actually hear her cry out in name in such a lewd voice…

If his heart could beat, it would be pounding.

The least he could do to show his appreciation was to pound her pussy instead. That decision proved to be a fantastic one, for she ended up crying out his name even more!

He was in love with it.

It wasn't just her voice communicating how amazing she felt either. Her insides were becoming increasingly compact, though it wasn't more difficult to fuck her due to how drenched in fluids she was becoming either. By this point, his body was operating completely on instinct, just as she advised. It felt good to thrust, so he thrust. It felt good to watch her, so he watched. It felt good to listen to her moans, so he listened. He was in a flow that he didn't wish to disrupt at all.

Flayn was absorbed in her own cadence too. The consistency of his thrusts were keeping her moans consistent and loud. It felt a little embarrassing to hear these sounds emerge from her lungs so effortlessly, but they were having quite the effect on her man, so she didn’t mind that much!

She was so close! So, so close!

“Byleeetttthhh…” she cried out again. “Don’t stop… don’t stoppp… dddooonnn’ttt ssstoooppp!!!”

She had never sounded so volatile before. Her body was on the brink of a complete and utter meltdown, all thanks to the constant bashing he was giving to her womb’s entrance. It was awakening incomprehensible feelings within the both of them. Nothing mattered more than the ridiculous level of pleasure echoing through their bodies.

He was close too.

Deep down, he knew it was dangerous to cum inside her… but at the same time, the thought of filling her up was hot. Not only that… but what better way to express his love for her?

While they were dating, they hadn’t yet declared their love for each other despite all the things they had done.

But Byleth knew what these feelings were now. It was unmistakable. He had truly fallen for Flayn.

It was about time he told her that.

“Flayn… I love you…!” Byleth confessed to her, right on the verge of an amazing orgasm.

“I love you too, Byleth!” she confessed back with absolutely no hesitation. Hearing her respond so swiftly was shocking enough, but he found himself focusing most on what she had to say next. “...cum inside me! Cum inside me, Byleth!”

The complete need in her voice was astonishing to hear, and exactly what he needed to eradicate his lingering doubts. Potential consequences be damned, he was going to give her-- and him, a magical end to their first of many times.

“Flayn… ah… I’m…!”

He couldn’t finish his sentence. The bliss was too much.

Flayn was happy to encourage him anyway. “Yeeesss!! Cum inside meeeeeee!! ”

Right as she finished her demand, he granted her wish. Byleth found himself ascending to tranquility as he filled up Flayn’s pussy for the first time, painting her womb white. He wasn’t alone in his climax; Flayn experienced a magical one too, enhanced by the feeling of his cock

Byleth completely collapsed onto his lover, and in turn, she wrapped her arms around him and held him close, not wanting him to leave her side.

Both were completely worn out and completely out of breath by this point, but such a feeling had never felt so strangely wonderful.

“...Byleth…” she mumbled, almost on the verge of slumber.

“...yes, Flayn?”

“I love you…”

“I love you too.”

Flayn squealed in delight. “Say it again.”

“I love you.”

“Again!”

“I love you.”

She squealed again.

Who knew such a cheeky devil could be so adorable?

Ah, who was he kidding? Flayn was the pinnacle of adorable. She always was, and always will be.

He embraced her in a tighter hug, more than happy to fall asleep with her like this. Flayn shared the same sentiment, more than happy to use her lover’s chest as a new pillow.

Little did they know that there would indeed be consequences for their actions.

This was an important night-- not just because they had confessed their love nor had sex for the first time… but because it was also the night their baby was conceived.

But neither Byleth nor Flayn regretted it, even after finding out.

Why would they?

They loved each other, and they loved their unborn baby too.

“Byleeetthhh… Byleeeetttthhh… I love you… I love you!!!”

Byleth was pretty certain that Flayn’s sexual appetite was at an all-time high. He wasn’t sure if it was due to her love for it constantly increasing, or due to an effect of her pregnancy, but he was always more than happy to please her. Watching him ride him with such force while radiating so much lustful love from her expression was always amazing to witness. He’d never grow tired of it.

“Flayn, you need to be a little quieter,” he teasingly warned her. “Someone might hear you. If we’re caught, that’s going to spell trouble for the both of us.”

It was amusing that they used to sneak out so often to do lewd things, and while they certainly still could, the risk was never greater. It was a bit of a shame, but soon enough they’d be able to return to the great outdoors and get up to no good. On the plus side, Byleth’s bed was not a bad alternative.

“But… ah… you like it when I am loud!” she pointed out, cheekily grinning at him. “You love it when I cry out your name, do you not?

“I do… but we can’t be too risky,” he countered.

“But taking risks is part of the fun!” she whined playfully, and honestly, she wasn’t wrong. He was just as addicted to the thrill as she was. “No one is going to suspect that the girly moans coming from the professor’s room are from the girl who has been missing for months~”

Byleth was absolutely the last person on everyone’s list when it came to potential candidates for her alleged kidnapping.

It was only fair to let have her way; she was essentially trapped in this room, so entertainment was certainly limited whenever he was out teaching. They had thought about just telling Seteth the truth early, but since they only had a month or two left to go… they figured they might as well see this through to the end. He felt bad leaving Flayn here all the time, but she insisted she was entertained enough; Byleth often brought her books to read, and no one suspected a professor of all people borrowing plenty.

…he just hoped no one would notice the stains on a few of them once they were returned. There were times they had fucked without even getting to the bed. Lust was an unstoppable monster sometimes.

While Byleth planned to conveniently “find” Flayn after her birth, he wasn’t sure what he was going to do if the baby looked like him… if that happened, then it would be obvious that-

His thoughts were interrupted suddenly when Flayn’s lips smashed against his, completely disrupting any ability to function.

“You are worrying too much, honey,” she comforted him, pausing their love-making so she could pat his head. “There is no need to concern yourself about the future. It will work out in the end. All that matters is that we’re going to have a family. We are going to be happy no matter what.”

Flayn knew him so well by this point. She could recognize what the slightest differences in his facial expressions meant.

But she was right. There was no point thinking about all those “what ifs”. It was best to take things one step at a time.

…which meant that right now, his focus should only be on making love to his beautiful girl.

To show him his priorities were in the right place, he decided to take charge, deciding she deserved a little rest. He carefully lowered her back, meaning he was now the one towering over her.

This position was nostalgic; they had shared their first time like this. For that reason, even though the position was arguably basic, it was very special to them.

“...make love to me, Byleth…” Flayn begged.

He was fully intending on granting that wish anyway.

He was gentle at first, always subconsciously aware of the baby in her tummy, but it was very obvious she was craving rougher play.

So he accelerated, using those loud moans he loved so much as fuel. He wasn’t too fast because of her condition, but it was still a satisfying pace for the both of them.

He felt silly! Why did he ask her to quiet down?! She was absolutely right-- he loved those adorable noises she made.

Because of her pregnancy, he couldn’t quite climb on top of her like last time, but nevertheless, he made sure to emulate their first-time as much as possible. She was quite the romantic when it came to anything resembling their first-time together; this position, the location, as well as how much they were crying out each other’s names, did a good job at making them feel nostalgic.

Byleth was the first to give in, filling up his beautiful lover with the cum she loved so much. Like always, she came alongside him, amplifying the intensity and pleasure of their joint climaxes.

“...I love you, Flayn,” he told her.

She always liked being told that after they made love.

“I love you, Byleth!”

“I love you more.”

“I love you the most!”

Flayn later gave birth to a healthy baby.

He had hired someone specialized in helping women give birth beforehand, making sure they stayed hush-hush about the situation with a generous tip.

It was also during these weeks that Byleth established some connections with Abyss, allowing him and Flayn a place to stay to look after their child, and there were also plenty of people to hire for babysitting; with how high their rates were, almost everyone was willing to take up the job. They made sure to stay away from the Abysskeeper and Mr. Backup however-- they directly reported to Seteth!

It was a bit of a risky move moving things to Abyss, but they were all about the risks.

The reason for them doing this was because they wished to avoid a situation where Flayn reappeared with a baby.

They both believed this scenario would probably give Seteth a heart attack, so they decided it was best to introduce the baby later once her presence was the norm again.

The plan was to have Byleth find Flayn in a deep part of Abyss.

It sounded good on paper.

They hadn’t accounted for the Death Knight, however.

Byleth had no idea why he was lurking around near Abyss, but Byleth took advantage of his appearance by making quite the commotion about it, claiming the Death Knight was the one behind Flayn’s disappearance.

Seteth came running, and Byleth helped him defeat the Death Knight. While he wasn’t captured, Flayn appearing right afterwards sold the story that the Death Knight was behind it. Seteth was especially furious at the masked man… and Byleth was glad about that! He did not want that anger directed at him.

Fortunately, Seteth wasn’t furious for long. He had his precious daughter about, and their reunion was an emotional one.

He felt awfully guilty when Seteth took him to one side and thanked him while on the verge of tears.

Byleth would eventually apologize… and probably face a furious Seteth, but at least that wasn’t anything he’d have to worry quite yet…

In the end, he believed Seteth would end up being okay with things, especially after seeing that he had a grandchild! Flayn believed that all would work out once Seteth had an opportunity to be a grandfather for the first time by holding the child.

Hearing her say that convinced him. He’d soon be sharing in their happiness.

The relationship Byleth and Flayn had was an unorthodox one to say the least, but they were happy with how things were turning out.

“Honey… I have a favor to ask of you,” Flayn tugged on his clothes, craving his attention. “Do you want to sneak off somewhere? There are a lot of fun spots we haven’t visited in a while… and I would love to re-experience them. What do you say?

She had only been back for a day… and she already wanted to take more risks…

Ah, why not?

He liked taking risks too.

Especially with her.

Everything was better with her.

Flayn-- the mother of his child.

“...you look like you are thinking about how much you love me again,” she observed.

“I am.”

“...oh! Well… ah… I love you too…!”

The adorable mother of his child!
