Alright, third story time! This one is a request from Temporal King, who wanted a Robin x Lissa x Maribelle polygamy story. This is my first time writing a threesome as well as my first time writing something with heavier romantic themes, so just bear with me here! XD

All characters are 18+


The sun shines brightly on the Halidom of Ylisse, as it often does. The air is warm, the birds are singing... and Maribelle is pacing back and forth in her bedroom, thinking quite deeply while her best friend watches with worry.

"Maribelle, I don't know what's going on, but all this pacing is really annoying!" Lissa finally says, cutting into the silent tension and gaining the attention of her long-time friend.

"Oh, Lissa darling... If only it were so simple. You see, we both face a common problem, yet there has to be a rational solution! There just has to be!"

"You mean our mutual Robin problem?" Lissa asks, piecing together what this is about. It's true, both women were absolutely head over heels in love with Robin, with the only problem being that they were both in love with him. Neither girl particularly wanted to win Robin for themselves while leaving the other to be alone, and at the same time it would kill them inside to give up and see Robin live happily ever after with the other. This whole situation was an annoying double-edged sword.

"Yes, I fear that is the one..." Maribelle says with a sigh, sitting down on the edge of her bed. "We cannot ignore this issue forever. I fear I just cannot, for the life of me, think of a solution that ends with all parties involved happy..."

"Listen, you shouldn't stress over this so much. I'm sure there's an answer, we just aren't looking in the right places."

"Whatever do you mean, my dear Lissa?"

"Well, just think about it! If we're struggling with love, why don't we go ask some of our friends in the Shepherds who actually are married, or at least in a relationship?" Indeed, in the three years that have passed since the war with Plegia, several of the Shepherds have settled down and gotten married in this time of peace.

"Hm... That could be worthwhile, actually. I believe Lady Cordelia and Sir Frederick are a paragon example of romance-"

"Yeah, but..." Lissa interrupts, earning a brief glare from Maribelle, though the noblewoman doesn't dwell on it too much. "Those two are so duty-bound to my brother that they probably haven't even figured out what real romance really is. ...Actually..."

"...What is it you're thinking?"

"Chrom! He's been so lovey-dovey with Olivia for almost three years, plus he knows Robin probably better than we do!"

"Er, Lissa... No offense, but King Chrom is a very busy man... I doubt he would have time to give romantic advise to anyone. And are you sure that he is even qualified to be giving advice on such matters? He's not particularly known for his deep insight."

"Well, he's our best bet right now. C'mon!" Getting up and grabbing Maribelle's arm, the noblewoman is promptly dragged from the room, the princess set on this new idea.


"You want... what?"

Chrom is sat at his desk, thankful to be able to set his paperwork aside for a moment, but he'd hardly expected this when his sister barged into his office, Maribelle in tow.

"Love advice! We need the insight of someone who's in a successful relationship!" Lissa declares, hands on her hips. "So, we chose you!"

"Love advice... for you two? I'm hardly a relationship counselor, I think you would be better off talking to-"

"N-No, we do not mean for our own relationship! Lissa and I are not a couple, and I take offense in your assuming as much!"

In truth, Maribelle's outburst comes from the fact that there is a definite attraction between the two women, and they'd be lying if they said that they haven't found themselves in particularly intimate situations in the past. It's a sensitive subject.

"No, you dunce, we aren't talking about a relationship between us" Lissa says bluntly, probably the only person alive who will insult the King of Ylisse without hesitation, but Chrom would honestly think something was wrong with her if she didn't. "It's about a certain tactician that you're familiar with..."

"Robin? Lissa, I didn't know you were interested in him like that? But then why is Maribelle... Oh."

"Now you understand our predicament" Mirabelle says, now that Chrom has put the pieces together. "We both fancy the man, yet we are having difficulty deciding which of us should confess our feelings to him. It has become something of a rivalry to gain his affections that has not only strained our relationship, but I fear has pushed him away from us as well."

"Hm... I can see how this would be a problem for you two" Chrom responds, leaning back in his chair and thinking for a moment. "Luckily, you girls aren't alone in this. After all, Robin is my best friend and closest advisor, remember? I just so happen to know that he is rather taken with you two, possibly even more than you are with him. And he's been distancing himself not because of your competition, but because he doesn't want to hurt either of you by choosing one over the other."

The news that their shared crush shares their feelings makes their hearts flutter with joy, though the fact that he likes both of them just might complicate things further...

"I mean, we're happy with the news, Chrom, but..."

"That doesn't particularly help our situation!"

Chrom chuckles, finding amusement in their plight. How these two, let alone his brilliant tactician, haven't thought of the easiest solution to this is beyond him. "How doesn't it help? ...You do both know that polygamy is commonly practiced in Ylisse's high society, right?"

Lissa and Maribelle stare at Chrom, then at each other. Why didn't they think of that?

"I... I must admit that you have a point... We hadn't considered that as a possibility..."

"But... Are you sure you're okay with that, Chrom?"

"What, my sister being married to both her best friend and mine?" Chrom asks with a smile. "While I'll admit, I'd prefer you to have the sole attention of just one partner, I can't deny that this seems to be the best situation for everyone. And there's nobody I trust to take care of you more than Robin and Maribelle."

Lissa blushes with embarrassment from her brother's words, but it's a huge weight off her shoulders to know that she has his blessing for this relationship. Maribelle, on the other hand, is blushing due to the fact that she can potentially be with not one, but both of the people she's held romantic feelings for.

"As wonderful as this news is..." Maribelle starts off. "I would still need the blessing of my father, just as Lissa needed yours."

"Ah, you don't need to worry about that either" Chrom says, his smile never faltering. "I've been in contact with your father over this topic ever since I found out about Robin's dilemma. He said that you marrying both the Princess of Ylisse and a high-ranking official in my court would be a great boone to your family, especially as you prepare to become head of your house. Though, if I'm being honest, we never mentioned this to either of you or Robin because we thought you would come to the polygamy conclusion on your own."

The two noblewomen are left speechless. They could've had all their dreams come true if they hadn't overthought the situation and missed the obvious solution!

Once again, Chrom chuckles at their reactions to all of this. "Listen, it's already evening, and I made sure to send Robin home early today because he's been working so hard lately. Why don't you both head over and tell him the good news?"

Maribelle and Lissa look at each other and nod, with lustful intentions behind their smiles.


Robin is at his house, a much larger house than he would've liked in one of the neighborhoods closest to the castle. Robin had been fine with living in a room in the castle or even in the Shepherds' barracks, but Chrom insisted on giving Robin a place all his own.

It's not too bad though, plenty of privacy for him to do whatever he wants, though he's not actually here enough to really explore that subject. At least it provides a comfortable place to sleep, though Robin would much prefer having a certain pair there with him...

Finishing washing up in his bathroom, Robin steps out into his hallway, wearing only a black bathrobe that actually resembles his tactician's cloak in design. The robe was actually a gift from Anna, who had it tailor-made as a thank you for being one of her most supportive customers.

Robin heads down to his living room, honestly quite bored. It's not until he isn't working that he realizes just how little he has to do outside of work. Maybe he should just go to bed early... After all, getting an early start tomorrow would help him make a bigger dent in the paperwork that's piled on his desk. His thoughts are interrupted by a sudden knock on the door. Wondering who in the world would be visiting him this late in the evening, he walks over to the door and opens it...

"Lissa? Maribelle? What are you two doing here?" Robin asks as both of the women of his dreams push themselves through the front doorway the moment he opens it. He notices that they're wearing sun dresses; Lissa with a yellow one and Maribelle with a white one. It's definitely a change from their usual attire that he's so used to seeing them in.

"Well, that's no way to greet a princess!" Lissa huffs with her hands on her hips, though her expression quickly changes into a smile. "Actually, we're here to visit you!"

"Yes, it's true. We had heard that you left the office early today, and it just so happens that we have some free time of our own to spare. Therefore, we have elected to grace you with our presence."

"Er... Thanks?" Robin says with a chuckle. "I can't say I have much in the way of food or drink though, the maid I hired isn't bringing groceries until tomorrow."

"Oh, don't worry about that. We aren't hungry anyway!" Lissa chirps before Maribelle can complain that she's feeling a bit peckish. "Actually, we have a bit of a surprise for you~"

"Um... What do you mean?"

"Well, we heard from a reliable source that you have a thing for both of us~" Lissa purrs as she hugs his right arm.

"And, after a talk with this reliable source, combined with the fact that we happen to feel the same way about you~" Maribelle takes his left arm in her arms.

As Robin tries to register this sudden information that he's been given, both women stand on their tip-toes and kiss his cheeks at the same time, causing his face to flush red as it finally clicks in his head what they're saying. "Wait... You mean... Both of you...?"

"Yup! Turns out polygamy relationships aren't too uncommon among the nobility of Ylisse. How we, and especially you, didn't think of this is crazy, but whatever. Now we know, and here we-"

Lissa is interrupted by Robin's lips pressed firmly against hers. Once the princess is sufficiently dazed, Robin breaks the kiss and turns to the proud noblewoman, who takes the initiative herself and kisses Robin deeply, the two of them relishing the chance to finally do this. Breaking the kiss after a few moments, Robin puts his arms around both of them.

"Let's take this to my bedroom."


They'd barely made it into bedroom before their clothes were off.

Lissa's dress was dropped right in the doorway, preventing the door to close all the way. Maribelle's dress is only a few inches away, mostly buried beneath the bathrobe that Robin was wearing. And on the floor at the end of the tactician's king size bed is a pile of smallclothes from the three people.

All three of them are naked on the bed, Robin laying on his back with Lissa on top of him and Maribelle next to him, her lips once again locked with his. Robin's hands are wandering over the princess's body as she grinds her wet sex against his quickly hardening cock. His hands stop on her small, perky breasts and gives them a squeeze, earning a pleasured moan from the princess. Lissa, impatient as always, wastes no more time and slides the man's rather large member into her tight royal cunt.

"Mm... That feels so good, my Prince~"

"...'My Prince'?" Robin asks, briefly pausing.

"Well, marrying a princess makes you royalty. I doubt your job with change much though."

"...Fair point." Robin grabs her hips and gives her a thrust, causing Lissa to moan out loudly.

Lissa begins riding his dick in the cowgirl position, bouncing up and down on his lap. Maribelle, not to be left out of the pleasure, adjusts her position to be on top of Robin, facing Lissa, with her pussy right on his face. Already knowing full well what he's expected to do, the tactician moves his hands to Maribelle's thighs and grips them, relishing in how soft they are before plunging his tongue into her already soaked cunt.

Moaning from the attention to her pussy, Maribelle turns her attention to the other object of her desires: Princess Lissa. With this new polyamorous situation, there is no excuse to continue ignoring her long-time attraction to her best friend that was surpassed only by her attraction to the tactician. Maribelle leans forward and captures Lissa's lips with her own, and the girl riding on Robin eagerly and happily returns the affection. The noblewoman's hands begin to wander the princess's body, stopping at those small, perky breasts of hers and giving them a squeeze. She gives some extra attention to Lissa's nipples, pinching and rolling them between her fingers, an action that Lissa seems to enjoy quite a lot.

With the trio's combined pent-up lust for each other, it's not long before they each reach their first orgasms. With Robin's attention to Maribelle's pussy and especially her clit, Maribelle's attention to Lissa's breasts as a whole, and Lissa's bouncing up and down on Robin's cock, all three of them make one final push before erupting. The women's juices cover Robin, some of which he more than happily laps up from Maribelle's pussy while his warm seed fills Lissa's canals and womb, making her feel all warm inside. They all stop to catch their breaths after such euphoria.

Deciding that to be enough for now, Maribelle and Lissa get off of Robin and take their places laying at his side, while he promptly puts his arms around them. They all definitely had more stamina, but perhaps it was better to take a moment and relish this wonderful moment of being in the arms of their beloveds while covered/dripping with various sexual juices.

"I love you. Both of you" Robin says with a smile, giving them both a quick kiss on the cheek.

"And we love you too, my dearest Robin. Forever and always."

The trio of lovers simply lie there, taking in each others' presence and warmth, something that they've dreamed of for so long. Though, they have a sneaking suspicion that they'll be spending a lot of time in the bedroom. Or Robin's office, whenever he's working late.

"...You know Robin, now that your going to become royalty, don't be surprised if Freddy tries to move rocks out of your way when you walk" Lissa cuts in after the moment of sweet silence between the three.

He pales, realizing that there just might be truth to her words. "Oh Naga, I have to deal with him now, dont I? I'm going to walk into the mess hall and see myself naked holding a sword and scale just like Chrom did... I just know it."

The look of horror on Robin's face makes a naked Lissa laugh while Maribelle, still being a lady, holds onto a small blanket covering herself and tries not to laugh at the look of fear on her new fiancé's face.

Yes, they certainly made the right choice.


And there you have it! I know the actual lemon scene was a bit short compared to my last two stories, but this was my first time writing a threesome so I think it went pretty well. Also shoutouts to Chrom for being the best wingman for all parties involved.

If you enjoyed this story, leave a review! If not, feel free to drop some constructive criticism to tell me why.

As always, I do requests! If you have a smutty FE story idea that you want to see come to life, just PM me and we'll talk! I'll consider just about any pairing, as long as it doesn't involve underage/lolicon/shota characters.

Thanks for reading, and I hope to see you at my next fic!
