"Oh, hey Professor! I was looking for you."

Byleth rolled her eyes as Sylvain walked up to her while the newly appointed professor was checking up on their stock of weapons. "What do you want? Going to attempt another flirting session?"

"Perhaps," he admitted. "But no, I do have a question relating to the last time we spoke about such things." She sighed and turned to face him, crossing her arms in preparation.

"What is it?"

"So, you've been a mercenary your entire life, right?" he asked.

"Yes, ever since I was able to first wield a sword," she replied.

"So you've been surrounded by mercenary men and the like for years?" he pushed further.

"Yes," Byleth answered, not sure where the man was going with this.

"Aren't mercenaries really rowdy?" he asked.

"They can be. Can you please get to your point?" she asked, and he raised his hands in surrender.

"I'm almost there. My main question was that if you've been surrounded by those kinds of men your whole life, haven't some of them tried to…you know?" Byleth raised an eyebrow, clearly not understanding. He sighed. "Haven't a bunch of men tried flirting with you before? Or maybe even tried to-"

"Any man that tried to touch me, even when I was too young for them, got my sword in their stomach or my fist in their groin before my father kicked them out of the group," she answered. "And yes, they have flirted with me many, many times. And I've always said no, for the same reason."

"Which is?"

"What's the point?" Sylvain looked shocked at that.

"What's…the point?" he repeated.

"Yes. What's the point of sex? Surely it can't be anything that special," she said as she glanced back at the weapons, wishing this pointless conversation could end already.

"You…wow…" Sylvain looked utterly baffled by this point, so she ran a hand through his hair and sighed. "Well…it's hard to properly explain…"

"Then why bother?"

"Let me finish," he said calmly. "It's hard to explain…so why don't I show you?" Byleth raised an eyebrow. "One session, one night, and I assure you I can make you see what the 'point' of sex is. What the appeal is." Byleth once again rolled her eyes and turned to leave, but the man grabbed her arm. "Hey! I'm serious!"

"Surely it can't be that good," Byleth said, but Sylvain shook his head.

"Just one chance. That's all I'm asking for." Byleth wasn't sure what it was, the certainty in his gaze, or the determination in his voice, but she found her resolve weakening.

"One chance," she finally said, and he smiled brightly. "And only if you never speak of it to anyone else. I don't need the reputation of being someone who fell for your weak 'charm'." He nodded.

"Of course. Meet me after sunset, in my room~" he said and gave her a wink as he left.

She was already beginning to regret her decision.

By the time night fell, the professor was already at Sylvain's room, and all it took was one knock for him to open the door and let her in, locking it behind her. She'd made sure nobody had seen her so rumors wouldn't unnecessarily spread, either.

"You won't regret this," he promised.

"I better not," she said as she immediately began to strip. His eyes widened at the sight, and he quickly began to do the same. They faced each other as they stripped down, removing layer after layer until it came time for Byleth to remove her bra. As it came off, exposing her large bust to the man, his eyes widened and his smile grew large. She didn't pay it much mind as she then dropped her panties as well and finally left herself completely nude in front of the boy. He paused with his hands on his own underwear as he stared at her in shock.

She was shaved. Now, normally, she wouldn't have found any reason to do so, never mind the fact it was a little hard to do with the tools she had available but…she still did it. Not for anyone else's sake, but because she liked how it felt when she felt bare. It made her feel…cleaner, at least in her mind. But now as Sylvain stared at her groin in awe, and she could see the straining tent in his boxers, she allowed herself a small smile, happy that at least someone was getting to appreciate it.

"Are you going to finish?" she asked when he hadn't stopped staring at her body for almost a full minute. He shook his head.

"R-Right, sorry, you're just…so gorgeous…" he said and finally dropped his underwear. Byleth opened her mouth to reply, but her voice caught in her throat. His cock was…impressive, to say the least. More so than she would've actually expected. She wasn't sure what it was, but looking at it gave her a weird sense of…excitement. "Okay, so…" he went on, apparently unaware of the effect he was now having on her, "since you seem to be completely inexperienced, I'll take the lead and guide you along, alright?"

"Alright," she responded, and walked over to the bed, sitting down as he followed her and gently eased her onto her back. He climbed over her, and despite the flat expression she currently had on her face, it was clear he was excited, if his hard cock wasn't a sign enough of that.

"I'm going to start by getting you wet, because if we go in without doing that, it isn't going to feel good, alright?" Byleth nodded. She knew the basics of how sex worked, but it would be interesting to see it firsthand.

But she didn't truly know how good it would be until he reached down and grabbed her chest.

Instantly, a strange noise escaped her lips, and her eyes widened. His smile grew as he ran his fingers across the skin of her large bust, gently brushing past her nipples as well. Byleth felt…odd. Sure, she'd been grabbed at her chest before, to which she then usually cut off their hand, but this felt different. The careful tracing of his finger across her skin felt like a ghostly presence that sent a tingle down her spine.

And when he fully grabbed her chest, a gasp left her throat.

"Are you starting to get it?" he asked, but she didn't answer. More lewd noises flooded from her lips as he massaged her chest with a strange sort of surprising tenderness. His fingers sunk into her soft flesh, and he moved them back and forth as if testing them for something. "Do you want me to go further?" She gave it some consideration. She was already beginning to feel…something. So she nodded.

His squeezes became harsher, using his entire hand to almost crush the breast in his palm, but yet…it only made her feel even better. She felt a tingle between her legs that made her thighs rub together as he then did something new. He pinched her nipple and gave it a slight twist. Instantly, white-hot pleasure rocketed through her and her knees went up as her body bent. She let out a gasp as her cheeks flushed, and Sylvain gave a satisfied smile.

"Like it?"

"A-A little…" she said and gasped again as he removed a hand from her breast and pressed a finger against her slit. She could feel it was damp.

"Your body certainly says so~" he teased, and began to run the finger up and down her lips. Her moans started coming at a steady rhythm as he pleasured her with both hands while leaning his head down to place his mouth over her other nipple. The pleasure increased with every second that went by, and she felt it becoming harder to think.

Eventually, he eased his finger inside her as he bit down gently on her nipple. That caused a great moan to surge from her lips as her body began to thrash, unused to such an incredible sensation. She was already at the point where she could see the appeal, but she wanted more. It was clear Sylvain could tell, as he started to thrust his finger in and out of her, slowly at first, but quickly speeding up. He pulled at her nipple with his teeth, letting it go and watching her breast jiggle before he attacked it again. He clearly had the experience to back up his words, and Byleth was melting at his touch.

And then, all of a sudden, he retracted his finger. She let out a shaky breath as he also pulled away from her breast. She gave him a confused look.

"Since it's your first time, I was worried that you had a chance of cummimg too fast," he explained. "So now that you're wet enough, we're gonna move on."

"T-To what?" she asked as she felt something press against her pussy.

"This," he said as he pushed the head of his cock inside.

Two things hit her at once. The first was a pain that made her cry out, but the second was a new kind of pleasure that quickly washed over the pain and almost immediately drowned it out. She shuddered as she felt the intensity of the action in full force, but already she wanted more. Her hips trembled, and Sylvain smiled. "Already ready for more?" She nodded, and so he pushed in more. He began to ease his hips back and forth as he slid in and out of her easily, and with every entering, he pushed in a little deeper. Her breasts jiggled with every thrust, and so he gripped both breasts tightly with his hands once again and squeezed them, only adding to her pleasure further.

Before long, he was completely inside her, and the thrusts were growing in intensity. Her moans were at an all time high, and she would be surprised if anyone couldn't hear her at this point. But she didn't care. It felt too good. She felt a swirling inside her body that was growing more and more. Sylvain grunted as well, almost as much as she was moaning.

They kept at it for a while, and every thrust felt like a sent a bolt through her body, through her nerves. It was incredible and powerful and she never wanted it to end. But she could tell from the pressure building up inside her that sooner or later, it was going to. She didn't know how to control it, didn't know how to stop it.

So, as Sylvain moved as fast and as hard as he could, Byleth let out one of the loudest noises she'd ever made as she experienced her first climax. It flooded out of her like a river onto their bodies, even as Sylvain kept going. He was beginning to slow down as she pumped out everything she had but maintained his intensity. His balls slapped against her one last time as he plunged his entire length inside with a gasp and shudder. He came just as hard as she had, shooting his cum inside her womb and filling it almost instantly. He panted as it came out all at once, then in spurts, until he was finally empty, and their cum was spilling onto the bed. He collapsed onto the bed next to her as his dick slowly softened, and both of them stopped to catch their breath.

"Well?" he asked, and she did something strange. She let out a laugh. A pure, small, cute laugh.

"It was…incredible," she said, smiling wide, another thing she rarely ever did. She couldn't remember the last time she'd smiled this much or felt this good.

"See the appeal now?" he asked.

"I do. I really, really do," she said.

"And what's crazy is…there's so many different things you can do," he said. "Different positions, toys, objects, and you can do it with whoever. Two girls, two guys, hell, even three people can do it together."

"What?!" Byleth cried as she turned to look at him. He smiled back at her.

"Wow…you look more full of life than I've ever seen you, Professor," he said. She blinked. Two girls doing it together? How did that feel? What could they do together? The possibilities seemed limitless now. To think this was something she could've been doing for years…

"Wow…" Byleth said as she stared up at the ceiling.

"What is it?"

"I want more," she said, and Sylvain smiled.

"Well, I'd be happy to-"

"Everybody would be different, right?" Byleth asked, and Sylvain paused.

"Well…yeah, everybody does sex a little differently, and everyone has different kinks, so-"

"I want to try it all."

"What?" Sylvain asked as Byleth sat up.

"I want to try it all. Girls, kinks, people. I want to do it with everyone. See everything, try everything!" She quickly got off the bed and started grabbing her clothes.

"H-Hey, wait, that's-"

"Thank you, Sylvain!" Byleth cried as she leaned in and gave him a kiss on the cheek. "You've opened my eyes…I see there's so much to explore now. And so many people to have sex with!" With that, she quickly began to get dressed as she walked towards the door. Sylvain sat up as well. This was not how he'd thought this would go.

"H-Hey, where are you going?!" he asked, and Byleth, dressed once more, unlocked and opened the door, turning back towards Sylvain.

"I'm going to find another person to fuck," she said with the widest, more insane grin he'd ever seen. With that, she left, closing the door quickly behind her and leaving the man sitting there, slightly concerned.

"What did I just do?" he asked aloud.
