Work Text:
Dimitri was awestruck, to put it lightly. The mercenary-turned-professor was a total knockout, as Sylvain would have put it, but Dimitri was entirely too polite to ever utter such a phrase. Too involved in propriety, Dimitri simply pined as he hung onto every word the professor said in her lessons and dreamt of dancing at the ball with her, sharing a moment just after class, or simply stopping her as he walked past her on a free day just to ask about something they covered in class. Perhaps it was boring of him, but the last time he had a crush was not much better, handing the girl a dagger as a parting gift, but to him it was romantic. Symbolic. But with the professor… he didn’t know how to woo a grown woman. Even if she seemed to be the same age… she was always vague about that, as if she didn’t know either.
The times she asked to share a meal with him? Divine, although someone else almost always attended. Sometimes she invited him to choir practice, even though he wasn’t very good in his opinion. That time in the sauna? He felt it was so improper, a lovely woman inviting her male student to sweat in close quarters to “relax”; Dimitri couldn’t relax, his heart thumping a furious tempo as every nerve was electric, aware of every movement, every drop of sweat that glistened on her skin. The professor seemed refreshed afterward, but Dimitri felt exhausted from being so on-edge.
One day, after class, the professor asked him to train with her. One on one. No one around. In the evening when the training grounds would be the most empty. Dimitri was nervous beyond all belief, but agreed regardless because the last thing he’d wanted to do was disappoint his beloved professor.
His classmates caught on to his crush and teased him relentlessly. At least, his longest running friends did. Felix muttered how pathetic it was, Sylvain couldn’t help but try and advise Dimitri on how to make her swoon, but Dimitri found Sylvain’s methods questionable at best, repugnant at worst. Ingrid teased but wasn’t malicious. Dedue didn’t comment in it, and everyone else was either blissfully unaware, or too kind to bring it up.
So Dimitri agreed to meet in the evening and the nervous tempo he had become accustomed to in his chest only beat that much faster.
When he arrived at the grounds, the professor was already there, in her regular professor garb. Though many thought it a little odd, Dimitri found it endearing. The tights accentuated her long legs, leading into those tantalizing shorts that didn’t conceal much, to her bare midriff that he tried not to stare at but goodness it was a lovely sight. But her torso… her chest that almost burst out of her armor and the tiny shirt underneath. He had to admit it: he was definitely a boob man and Byleth’s bazongas were impressive.
Sometimes at night he thought of how luscious they were, how he wanted to suck on them, how he wished they could drip with sustenance that he would drink voraciously. He wondered if that was a normal thought to have, to think of a woman who was definitely not his mother as a sort of mother figure… sexually. It felt wrong but the thought went straight to his dick and it took all of his princely composure to not indulge. Oh how he wanted to though.
The professor smiled at him as he approached. “Thanks for meeting up with me, Dimitri. I wanted to check your form tonight without singling you out in front of the rest of the class,” she said kindly. “To be frank, you’ve seemed a little stiff lately and I wanted to try and loosen you up a bit.”
He was definitely stiff sometimes, but not in the way she meant. And to loosen him up… Dimitri didn’t want to loosen at all because it meant he might lose control and the last thing he wanted to do was cross a line that a student and professor shouldn’t cross at all. But it was tempting, he could admit.
“Oh, my apologies for appearing stiff. I suppose I’ve lacked in discipline, but do you think a private lesson is necessary? I would hate to take up much of your time.” He felt sheepish.
“I invited you, Dimitri. You are not taking up time that I’ve made to help you,” she said lightly. “Let us begin. Grab a lance and we’ll go through some exercises first.”
So they did that, practicing footwork and posture. Dimitri was still having trouble focusing as his gaze lingered towards her chest. Tonight was just all sorts of bad.
“You’re losing focus, Dimitri. Is there something bothering you?” she asked as she straightened, the lance going slack at her side.
“Oh, nothing of consequence. I’m sure it will pass,” he said blithely, hoping that would be the end of it. He wanted to leave and will his arousal away.
“Clearly it’s more serious than what you’re telling me.” She gazed at him, her eyes seeming to bore into his soul, analyzing every aspect of him. He knew nothing got past her.
“I think I know the problem,” she quietly announced as her glance flickered briefly up and down his form. She caught how he glimpsed occasionally at her chest. This wasn’t the first time a man stared, it certainly wouldn’t be the last, and it was becoming increasingly more obvious with Dimitri. She had noticed a while ago, and tonight she wanted to confirm it. With his classmates out of the picture, Dimitri was bolder in his looks which only confirmed Byleth’s theory.
It wasn’t unflattering, although she had never given her physical form much thought. She liked the way she dressed just because the clothes appealed to her and her father never said anything against it, so she never thought it was a problem. It was annoying if a man was persistent or felt he was entitled to her if he found her so attractive, but Dimitri was polite and kind and kept it to himself. Byleth didn’t care about advances because she quickly made it known she wasn’t interested, either by blunt truth or a quick twist of the wrist that left the man screaming. Not to say she didn’t engage in those sorts of acts with people, but when she did it was on her terms. But Dimitri was young and a prince so she felt no threat nor need to belittle him.
On the contrary, she was intrigued.
“Let’s meet in my room and have a cup of tea. We can discuss this privately.” She put away her lance and Dimitri followed, even though he felt nervous.
“If you feel it necessary, Professor, I will follow. I trust your judgment.”
“Good. I promise you, I won’t be harsh. It just needs to be addressed.”
Her phrasing left him ill at ease, wondering if she knew, but all he could do was talk to her. Maybe this would alleviate his feelings. He certainly hoped so.
The professor led him back to her room where she prepared a pot of tea. She offered him a snack, and he politely declined. His stomach was doing flips as it were.
He sat where she indicated and she focused her attention on making sure the tea was properly made.
“You enjoy bergamot, if I remember correctly.”
“I do! Thank you for remembering, Professor.”
“I would be a poor professor if I didn’t remember my students’ preferences. It’s how I guarantee your success. And all of you do splendidly.”
She was right of course. He felt that she was the picture perfect professor: attentive, knowledgeable, and most of all, kind. Apparently, this was an odd trait of hers. He had overheard her father, Jeralt, saying he had never seen Byleth so...happy. Her entire demeanor was completely different from her mercenary days, as if all along she was meant to foster talent and nurture, rather than be the ashen demon she was known to be. Byleth finally showed signs of life and interest rather than monotonous tasks and killing for pay.
“Thank you, Professor. We certainly are all motivated to do our best. We wouldn’t have this success without you. Your attentiveness is refreshing.”
She smiled gently. Dimitri would never tire of her rare smiles. “I’m glad I’m suited for the task. But speaking of motivation, I’ve noticed that perhaps you’re motivated in a different way. You’ve lost focus, and I don’t want you to pay for that.”
“My apologies, Professor. It’s something I know about, and I’m trying to address it, but, well, it’s something I haven’t dealt with in a while.”
“So you’ve been distracted by the female form before?” she asked. “I never thought you the type, Dimitri.”
He nearly choked on his tea. “Uh, well, that is to say…”
“It’s okay, Dimitri. You’re young and virile. People are only so strong. If you find me attractive, that’s okay. But you cannot let that hold you back on the battlefield. Outside of the battlefield though…” She looked away as if she was hinting at something.
Dimitri was completely oblivious to her suggestion. “I’m not sure I understand. Isn’t this inappropriate of me? It most certainly is. A prince, a student at the academy no less, should not feel this way towards a mentor.”
“It’s not unheard of, Dimitri. I’ve overheard other students commenting on Manuela, and even my own father.” Somehow, that didn’t seem to faze her. “I’m guessing that should bother me, but that’s how people are in my experience. I can’t say I’ve ever felt that way before, but working here at the academy has opened my eyes to things I never thought imaginable.”
Dimitri didn’t know what to make of that. “Oh? And what have you discovered here?”
“That I have a purpose outside of being a mercenary. I can teach, but I can also feel. It’s foreign to me.” She took a sip of tea and placed her cup down. “ Dimitri, may I be honest with you?”
“Certainly, Professor.”
“I’ve had sex before. That’s probably not entirely unsurprising, but I will say, considering I’ve never really felt before, it was all very casual, simply a task that was needed occasionally, and my father didn’t object to it when he found out. He knew I would never let something happen against my will, and was always very patient about discussions of sex.”
Dimitri considered that. “I cannot even begin to imagine a conversation like that with my own parents, but I never had the opportunity. Those sorts of things were taught very briefly by either a tutor, or maybe said in passing by my father in that I’d need to produce an heir some day, but I only knew about the act itself and was told to never act on it until I was married so my heir would be legitimate.” He finished his tea. “I’ve never thought of doing it for the sake of doing it. It was always implied it was improper.”
“How can something needed to have children be improper? And why would it feel good?” she asked seriously. “There’s nothing wrong with scratching an itch. Sometimes you need it to be relieved.”
“I suppose you’re right, but I shouldn’t. It’s improper.”
“Dimitri, have you...ever thought of relaxing your guard and letting yourself live for your sake rather than others? I suppose that’s how it is to be a noble, but I am of the opinion that sometimes you need to let yourself be rather than hold yourself to a standard that isn’t your own.”
She wasn’t wrong. Dimitri wished he could allow himself, but he was so entrenched in politics and Faergus traditions that he didn’t know how.
“I cannot deny it, Professor, but how could I do such a thing? Would I not be exactly like Sylvain?”
“Sylvain is self-aware, despite acting casually. And besides, I know his reasons, even if they are a bit too selfish. But it’s a way to cope, I suppose. He’s not the first, and certainly won’t be the last.” She stared at Dimitri as if trying to see through him and she did perfectly. Dimitri could only hold his own so well.
“Then… you’re saying it’s okay to let myself do this thing?”
“You’re an adult, are you not?”
“I am of age.”
“And from what I understand, I am too, although I was never told not to do it, so who am I, really? What am I? I do not know, so I do what I want.”
“I see…” Dimitri was very comfortable at this point. The professor had many good points and was encouraging and kind, just like his mother… like a mother would be.
That… wasn’t a polite thought. That wasn’t a good thought.
“Dimitri, I am your professor, and I only want your continued success. So I have a proposition for you.”
He was intrigued. “And what would it be, Professor?”
“If you slept with me, if I let you have me the way two people have each other, would that set you at ease so you could focus on class and our next mission?”
Dimitri was utterly shocked by this proposal. He wasn’t sure what to say.
“I… Professor, are you sure?”
“I wouldn’t have suggested it were I not. If this means you’ll do well in class, then it’s just another lesson. It’s my duty to set you on the right track. And the desires of the flesh are sometimes what is needed to do that.”
Dimitri gulped, but at this point he was too aroused and desperate to refuse. “Then I consent, Professor.”
“Wonderful.” She set the table with their tea aside and straddled him. “I’ll lead, okay?”
“Y-yes ma’am,” he stuttered as she ground her hips into his groin. Goddess it felt good.
She kissed his forehead and he responded with a whimper. She carded her fingers through his hair and he sighed. She kissed his cheek and he hummed at the gesture.
Her hands kneaded at his back and she felt him relax. She could feel him growing more and more erect and that only made her wetter. She hadn’t even seen his cock yet, and she already wanted it inside her. It felt big and all she wanted was to be ruined by it.
But this was about Dimitri and getting him off, so she would focus on that.
As Byleth began to kiss his neck, she felt Dimitri’s shaking hands reach for her chest. He gently grasped them and she chuckled quietly.
“They’re that enticing for you, aren’t they?” she muttered against his skin.
“Yes…”
“Then you will have them,” she replied as she took her top off. In the dim candlelight she saw his rosy cheeks blaze at seeing her bare chest, but he bit his lip as he resisted the urge.
“It’s okay, Dimitri. I know you want to.” She pressed her chest into his face. “Go ahead. Suck them.”
Dimitri bent his head forward and pursed his lips as he enveloped a nipple. Byleth patted his head.
“Good boy.”
Dimitri responded to that by sucking harder, grabbing her other breast more firmly, his other clutching her back, fingers digging into her skin as if he couldn’t let her go or he’d lose his mind to desire.
Byleth kept grinding herself into him and Dimitri lapped at her breasts, switching between them. He only sucked more and more fervently.
Dimitri did not know this, but Byleth was very aware. When her breasts were stimulated just right…
That’s when she felt it.
Dimitri was massaging a single breast with his hand as he sucked on it as well and he felt liquid drip onto his tongue. He thought it was sweat at first but it wasn’t salty. It was mildly sweet and he was confused. He pulled back to look and he saw that it was…
“Milk?” he asked, perplexed and a little worried. The professor wasn’t… Was she?!
“Dimitri, I assure you I’m not pregnant. Sometimes when I’m stimulated enough, they just leak. It’s not often, but it does happen. I should have warned you.” she said softly.
“I am...pleasantly surprised, Professor,” he admitted. “I-I don’t know why. It’s not like I’m...an infant.”
“Dimitri, it’s okay to have a mommy kink. It’s more common than you realize.”
He had no words. He didn’t know there was such a thing, but it made sense when he thought about it. It explained his thoughts at least.
“That’s reassuring,” he said, and with gusto he went back to sucking on them.
At this admission, Dimitri lapped and sucked like a nursing babe starving for his mother’s essence. His hands couldn’t let go of her. He wouldn’t allow it. He needed all of Byleth’s nourishment and her body. He was so at ease and for the first time in years he felt taken care of and loved.
Life as a prince was solitary. He had to be so strong, so it was nice that there was a woman who would ease his worries and give him the love he needed.
He was beyond hard now and she knew he needed to relieve himself of this desire so he could finally relax and get this out of his system. She pushed him back and began unfastening his top.
“Professor…?”
She looked up at him, eyelids hooded. “Don’t you need this, Dimitri?” she asked in a tone he couldn’t quite understand. It was both stern but comforting.
“Y-yes,” he whispered, helping her take his top off. He wore many layers as it turned out but soon he was bare-chested and the tips of her fingers gently grazed him. She cupped his face and kissed his lips.
“Mommy will take care of you,” she said in what he could only take as a motherly tone. And it only made his groin ache more.
Byleth got on her knees and began sliding his pants off. Through his undergarments his election strained and it was indeed quite large.
“That can’t be comfortable, sweetie,” she chided as she slid them off. He sprung free and she saw precum secrete from his tip.
“You’re so hard for Mommy,” she cooed as she leaned forward to kiss his shaft. “I need to take good care of you.”
“Th-thank you...Mommy…” he murmured so quietly Byleth could barely hear him.
“It’s okay, baby, you can say it out loud. Do you want Mommy to take care of you? You’ve been such a good boy.”
“Please, Mommy,” he quietly begged. “I’ve been good.”
“And you’ll be even better since Mommy is giving you a nice reward.” She grasped him gently, licking his tip. “Oh you taste so good to Mommy.”
“I only want to make you proud…” he whispered.
“Of course you do, sweet boy. And you do. Mommy is so proud.” She kissed his tip one more time. “Are you ready for your special reward?”
“Yes, Mommy.”
“Good boy.” She opened her mouth and took him in.
Dimitri was very large and Byleth could barely fit him in her mouth. Despite the role play, this was a full grown man’s cock she was sucking and damn it she would make this deprived young man feel so good he’d be begging for “Mommy’s special reward” every night.
“Mom-mmy!” he cried out as she deepthroated him. He bucked into her mouth, but she pulled back, his dick making a pop! sound as it left her mouth.
“Be a good boy. Mommy will take care of it.”
“Yes ma’am,” he sighed as she went back to it.
She sucked and sucked, tasting him, her tongue pressing against the large, pulsing vein as he moaned. His breaths quickened and that’s when she stopped.
“...Mommy…?” he questioned as he looked down.
“You’re being so good. Mommy wants to give you more…” she said as she stood up, taking her shorts and tights off.
Dimitri blushed as he saw her fully in the nude. She was beautiful and his dick twitched in excitement.
“I have the most beautiful mommy in the world,” he boasted as she moved towards him, spreading her legs as she straddled him. She was hovering over his cock, kissing his forehead.
“Are you ready for Mommy to give you an extra special reward?” she asked as she pressed her breasts into his face for him to suckle again. She was still lactating and wanted him to enjoy more of it.
He mumbled his admission against her breasts as he sucked harder.
“Oh you’re such a good boy, drinking Mommy’s milk. Only the best for you.” His tip was barely in. “Mommy wants to make you so happy.”
He pulled away to say, “You do, Mommy.”
“Such a good, sweet boy. Here’s your extra special reward.” She sank down on his cock, sheathing him completely.
Byleth had a few big cocks in her life, but Dimitri was definitely the biggest. She was going to be sore after this.
“Oh you’re such a big boy! You feel so good inside Mommy.” She started to bounce on top of him and Dimitri groaned.
“Mommy, you’re so good to me!” he cried out as she only sunk further into him, slowing her pace a bit so he could savor her slick pussy. “Thank you, Mommy!”
“Don’t worry, honey, you can thank me once Mommy is done. I need to know just how happy I make you.”
“So happy, Mommy, so, so happy!” he moaned as she quickened her pace again.
Byleth had an idea that she hoped wasn’t too out of line but it was hot in the moment. In his ear, quietly, huskily, she asked, “Does my big boy want a sibling?”
This seemed to stir Dimitri more because he yelled out a rather loud yes that Byleth had to place her hand over his mouth.
“You have to be quiet for Mommy, okay? You can have a sibling only if you’re a little more quiet.” She slowed her pace again. “But Mommy likes that you enjoy your reward.”
“I do! Mommy, please!” he groaned.
“Does my big boy want a sibling? Does he want to make a baby with Mommy?”
“Yes, Mommy, I want that very much!”
“Good boy. Mommy likes hearing that.” She bounced faster, clutching Dimitri’s face to her breast. “Drink up! I need you to be strong for Mommy!”
Dimitri didn’t have to be told twice as he eagerly sucked her breasts, draining her. He switched between them quickly, as one was becoming depleted and he needed more to sate his thirst.
“You need to come for Mommy soon, okay? Mommy wants all your yummy cum!” She gyrated sensuously as Dimitri moaned against her skin, knowing she was giving him permission to thrust into her as she bounced so he could reach his peak.
Dimitri’s breathing became erratic, his cries incoherent. Byleth knew he’d be done soon.
“Come inside Mommy! Give her another child!” she begged as she finally reached her own peak. “Oh baby, yes, Mommy likes that!”
Her pussy clenched his cock tightly and Dimitri finally exploded. Shots of semen squirted inside her, thick ropes of creamy cum filling her up. There was much more than Byleth anticipated as she felt her pussy being flooded with fluid.
“Ahhhh, Mommyyyyy….” Dimitri sighed as his orgasm finally subsided. Byleth still pulsed around him but he was slowly growing flaccid.
He kept his forehead pressed to her chest as she slouched against him, body limp with release. He felt as if he would never move again. It had felt too good and he knew he’d only want more.
She finally extracted herself from him and felt his spunk seep out. Dimitri felt a small splatter on his lap.
Post-coital clarity hit him. “Professor! I- I-! It’s inside…!”
She kissed his forehead. “Don’t worry about it, Dimitri. It’s been taken care of.”
He wasn’t sure what that meant but if she wasn’t worried, then he wouldn’t be. “Please let me know if….”
“I would of course, but it won’t be happening anytime soon, okay? It’s safe to come inside.”
“Yes, Professor.”
She cleaned herself up as she casually asked, “So you’re okay now? You think you can focus again?”
He realized he should be getting dressed. “Yes, Professor. This... tutoring , if you will, was most helpful. I will be back to my full capability.”
“Good. And should you need my assistance again, just let me know. Mommy will take care of you,” she winked as he finished dressing.
He blushed at that. “Professor, I didn’t know that part of myself, I assure you. I don’t know what came over me.”
“It’s okay. You like it, and I’m more than willing to partake. Besides, I liked it too.” She pursed her lips in thought. “I’ve never done parent/child role play before. It was fun.”
“I”m...glad you indulged me, Professor.” He moved towards the door. “I will see myself out.”
“Sleep well, Dimitri. I’ll see you in class tomorrow.”
“Yes, of course. Good night, Professor.”
“Good night, Dimitri.”
Years later, Dimitri’s mommy kink would make Byleth into an actual mommy, and he would be very pleased with that, as Byleth’s breasts produced nectar sweeter than what the goddess could ever offer.
