Exalted Fun in the Sun

Summary:

Two's company, Three's a crowd. And even a girl as mild mannered as Lucina can tell what kind of looks Severa is giving her boyfriend. It fills her with jealousy, and an odd sense of arousal both. So much so that the couple need to sneak off and discuss, shall we say... boundaries.

Work Text:

“Ugh… we’re at the beach and you two just choose to read!?” Severa huffed. She pulled her designer bikini bottoms out of her plush butt for the umpteenth time, if such a thonglike thing could be called a bikini. Those round cheeks had turned many heads at the beach, even Lucina’s a few times. But it hadn’t turned the one she wanted… 

Lucina dressed more sensibly, in the same blue and red swimsuit that she had worn all these years. It fit the same and she loved it so much, why try and replace it?

And Robin simply sat in black and purple swimtrunks, his bare muscles and cool confidence out for full display. Even as his girlfriend Lucina blushed and took glances. Not only that, she had noticed that Severa seemed very curious as to whether Robin took as much notice of her swimsuit. Or rather, what it covered. 

“It’s good weather for it, and the sun makes such a good reading light,” Robin smiled. Severa’s brow furrowed, in time with her rosy blush blooming. “Well… you should be having fun. Or is there a five-dollar word for fun that nerds like you use?

“That there is.” He smirked. Lucina’s eyes widened in surprise as his broad arm pulled her in close. “Lucina.” 

“Ugh, just fucking gag me and be done with it!” That was an… interesting choice of words from Severa. “I’m knocking off for a drink and some carbs. At least those never leave me bored!” She huffed before walking away haughtily, with that exaggerated hip sway. 

“You should get a swimsuit that cheeky, Luce.”

“R-Robin!” Lucina blushed. He always found ways to be bold when she least expected it, and every single time it turned her on.

“Mmm, you know that good girl angle won’t work on me. I’ve seen what you do when the lights are off.” His arm was still around her, kneading her modest breasts with fervor both sacred and sultry. 

“Now that our third wheel is gone, how about we fool around.”

Gods, yes…

“W-we shouldn’t. Severa was our ride after all. We should be doing what she wants. 

“You and I both know what she wants…” Robin raised an eyebrow. Yes, she did. Severa was here, birdwatching, so to speak. 

“She’s just lonely.” Lucina said. “She has always respected you and wanted your approval. It would be foolish to think those feelings would just go away just cause we’re dating. Be nice to her, dear. Give her a compliment.”
Robin raised an eyebrow as if to say is that all she wants?

No, no it wasn’t. It made Lucina jealous, but her skin tingled with warmth from the thought alone. 

“Gods, I must still have sand on me. I think I need to wash up.” 

“Mmm… Robin said, his hand slid down her back to tease the narrow strait of her back, his touch was so soft when he wanted it to be. Lucina barely felt his hands slip under her trunks-like bikini bottoms until he was kneading her ass. Soft palms, hardf fingers. Just the way she liked it. 

We should wash up…” He smirked.

 

“R-Robin…” Lucina moaned, as hushed as she could. They had chosen the most remote outdoor shower they could, a ways off of the boardwalk, away from the food and fun-havers that usually dappled the beach. Granted, a shimmering beach on a day like this was hardly a private matter. They could still hear the sounds of others washing up. Most stayed for only a few minutes, just enough time to wash off sand and salt, and get back to the fun. If they stayed a minute longe,r they may have realized that squeaky hiss was not, in fact the shower head

“Ahh… it’s so…” She whined, before a trickle of sense came to her. She pulled away from the hot kiss, looking Robin in the eye. “We can’t-” 

“I can do whatever I want. It’s only a question of if you can stop me.” His eyes were so handsome, Lucina always lost every argument for decorum in them. He grabbed the elastic band of Lucina’s swimsuit and yanked it down. Flecks of seawater splashed against his chiseled body and the shower walls, along with a stickier, sweety drip from her pussy.

“S-... Severa could be looking for-” 

“Knowing Severa she will be…” Robin’s voice held a husky, devilish cadence, one that drove Lucina crazy. He was so even-keeled, so by the numbers, so boring that nobody ever knew how utterly ravenous he could be in bed. Or in public in this case. 

His fingers lifted the swimming top Lucina had worn. She was always self conscious about her breasts. They weren’t even particularly huge, certainly enough for him to hold a handful, and slap that mast of a cock he had between them, but she couldn’t give him a proper titfuck. Maybe taht was just on account of how big he was.
Lucina felt that same turgid member press against her stomach, even in his swim trunks. “You’re really gonna make me go outside like this? Who knows what wanton thoughts women will think?” 

The thought of Robin with another woman filled her with enough envy to tear their proverbial woman’s hair out. But then again, watching Robin claim yet another girl, His broad back tightening as the woman’s arms and legs struggled and to tame his rampant thrusts. 

Severa wouldn’t be able to take it… Lucina told herself. She can play diva all she wants but I know she’s a virgin… 

That thought only made her more wet. 

Robin read the tells of her body like a children’s book. His fingertips rolled slowly against her lips, pressing just so to hear the wet gasp her lips made. Both those above and below. 

“God, you want it too.”

“I don’t-

He grabbed her neck, massaging the flesh softly. Lucina could feel his fingertips dimpling her rising breaths “Don’t lie to me, darling.” Robin said. His fingertips were slick now, rolling up her shaven mound past her trim tummmy, and finally curled into a fist under her swim trunks. 

He heaved the glossy fabric up, bouncing her tits aout. Cool from the seawater meeting open air, hot from the steam and the heat inside her body. “You know what happens to liars.”

“Yes…” She whined. Naga, she was getting overstimulated. The hot water kissed her bare skin at the same time that Robin kissed her lips. She met him with as much vigor as he had cunning. Their lips sucked at each other, tongues dancing in the open air, adding yet another source of slurry wetness. 

“Mmmm… Lucina whined. Robin grabbed her tender breasts and kneaded them. Thery were modest things, but Robin worshipped them as if they were as ripe and fertile as watermelons. 

“And you want my cock inside you right now.” He said. It was not a question. 

“Yes,” Lucina answered all the same. 

Gawds… Of course that fucking nerd ditches me. Does he know how many losers flirted with me on my lonesome!? And that Lucina How long does a shower take!?

S-Sev-”

Robin pressed a kiss against her mouth, to sciencealll her pretty little thoughts. His cock pressedagainst her stomach as well. He growled impatient and yanked the cord of his deep purple trunks. 

He pulled away, looking at her with those draconian, lust-filled eyes Lucina loved. 

Lucina heard knocking. It seemed Severa was knocking on every door. 

“Lucina!? You here!?” Followed by a rattingling rapp against the door. The doors were quite heavy too. They weren’t supposed to rattle…

“Robin… I” Robin didn’t say a word. With a thrust, he entered her confidently, brazenly even. Nnnhhh…” She whined, her world tinged pink as lust filled her. He began to thrust, quickly working it into the rhythm that was Lucina’s weakness “Haaah… Ooooh~”

“Good girl,” He moaned, before bunching the locks tight in his hand and thrusting deep inside her. His cock delved deep into the familiar strait of her gushing pussy. Lucina pushed her hand to her mouth just as Robin pushed her against the shower walls. He didn’t bother being soft with her. Both Robin and Lucina liked it far rougher than their well put together appearances will make. 

She was forever tight for him, and likewise he would forever stretch her out. She gasped, befitting some whore rather than a national fencing champion. His hand pressed against her trim abs, and she became meek and submissive at the push of a button. 

“Ugh! That bitch… And that fucking boyfriend of hers…” They could practically hear Severa grit her teeth. “And after all the effort I did to look good, they treat me like chopped liver.”

Robin leaned in closer to her ear, his thrusts jostling her with every motion. “Let her listen. I bet she touches herself constantly to the thought of me fucking her.” 

Lucina hushed her own mouth, tasting the salt on her palm. The other pressed against Robin’s pec. She wasn’t sure if she was trying to push him away or just hold onto the strongest thing within reach. Either way it proved little use in stopping him. His cock - and his body’s weight with it, drove inside and into her respectivey 

“That homewrecking little slut has been begging for my cock.” Robin’s whisper was soft and husky, yet the truth rang like bells in her ear. Severa had been doing everything to seemingly seduce Robin. Lucina knew she had her inferiority complex, and Robin was the very best boyfriend she could ever ask for. She knew that Severa likely didn’t have malice behind it, she just wanted the validation that came from having the upper hand. 

But… The way she would look at him, the way she would brush a strand of hair. That ludicrously tight swimsuit of hers.
It was two was two wisps of silk, barely pried together by a single metal ring, and the bottoms were practically a thong - a thong a half size too small for her ample rear at that! So indecent… All the men on the beach would have sore necks tomorrow trying to catch a glimpse of Severa’s sexy walk. All except one, which accounted for Severa’s crankiness today. 

Lucina pulled away to gasp. A bead of hot drool slipped down Lucina’s fingers. The more she thought of it the more excited she got. “She wouldn’t… it’s just.” 

“Only you.” Robin said. His fingers brushed through her wet hair so softly, gently, lovingly…

They heard a shower door exactly two doors down slam. No awards for guessing who had entered it. 

“And of course only the biggest douchebags appreciate all those squats I did for him…” Severa had always had a habit of talking to herself. “Is it my breath? I mean, I’m at least worth a little look, r-right? A-at least a thought…” 

Robin fucked his girlfriend like he owned her. Her wet hair was a leash in his hand, his meaty cock a rod to punish her with. The hot water ran a waterfall down Lucina’s curves, the powerful thrusts creating whitewater waves in both water and flesh both. Lucina’s hand slipped from her mouth.
Part of her wanted to stay silent, to rid herself of the mortification if Severa found out about her high libido. Especially after Lucina had chided Severa for so many things throughout their childhood, she would look like a total hypocrite succumbing to her base urges like this.b 

Another part of her wanted to be seen, wanted Severa to know how well Robin fucked her, that Robin belonged to her and lusted for her. She wanted Severa to know, hear, and feel the cock she would never feel, and be filled with as much envy and lust Lucina had been seeing Severa subconsciously flirt with her boyfriend. 

And yet another part of her wanted Robin to claim Severa. Press her face against the shower wall and fuck the redheaded slut. She wanted to hear Robin’s confident chuckle before he began to thrust into her, fucking her into the mattress, the counter, the wall, the floor - whatever would hold their weight. And Lucina wanted to watch. Watch as Severa barely took Robin’s cock, tears of joy streaming out of her clenched-tight eyes as Robin filled the girl who lied about losing her virginity with too much cock. 

Naga that was wrong of her, so why did it feel so right?

“Robin…” his sweet name spilled out of her mouthlouder than she expected. 

“Gawds… What the hell is that sound?”

Lucina’s hand pressed against Robin’t thigh, as if that would stop him once he got into a fervor. Robin answered it by pressing his fingers into Lucinas mouth.. Lucina’s mouth closed and suckled them. The act alone made her wet. The glossier, juicier liquid strickeld down her leg, beading with the condensate on her legs, and wafting the very steam with the scent of fresh sex. 

Naga, they were going to be found out… Severa was many things, but first among all the biting comments was that she was perceptive. She had to be, as Lucina’s rival. Lucina’s body begged for more while her mind begged for them to finish quickly.

Robin didn’t care. His thrusts slowly grew in volume, until they became wet plaps that rattled the door. He pulled his fingers out, but only to hook her cheeks slightly, stopping her from closing her mouth. 

“Moan for her. Moan for your best friend. Let her hear what a slutty little fucktoy you are for me.”
God he was so hot when he was dominant. Lucina felt like an obedient little girl in his clutches. Her breaths were moans, pants, unfinished begging. Her back arched against thehot steamy air and soon enough she was throwing it back just as hard as they got it. There wwas no secrecy anymore, certainly no benefit of the doubt. 

“What the hell… Hey! Whoever you are!” Severa yelled “The spring festival was Last week! If you two want to fuck like rabbits, you should have done it then!” That only made Robin fuck Lucina harder. He hoisted her up, pulling her close to exchange a hot, impatient kiss, before using that leverage to fuck her against the wall

Lucina held onto Robin’s neck for dear life. Every thrust  stretched her, jostled her, and fucked her senseles. “Ohhh… It’s sooo…” Lucina could thank the gods that her moaning voice was so much higher pitched than her speaking voice. All the while Robin teased as only a man as cunning as Robin could. He tweaked her nipples, thumbed her backdoor, kissed her possessively.

“Just my fucking luck…” Severa gasped in exasperation and half… something else. Robin didn’t care, he only fucked Lucina harder. Lucina bit her lip, her exalted eye glittering lustfully into his warm yellow eyes. 

“You’re such a devil…” She whined.

“And you love it.” He said, before kissing her. Hot, sloppy, and loud. The both made sure that the sound was as audible as her lips down under. 

“Fuck…” It was neither one of them who said it, but that third, shrill voice, oft prone to belting out viperous criticism. They heard a new wet sound join the symphony. 

“See?” Lucina could taste the smirk on Robin’s lips when he kissed her. “She loves it. Loves what she can’t have.

Too many fantasies swirled in Lucina’s head at that moment. Far too many to count. Chief among them was Severa realizing it was them in there. Perhaps they’d invite her in, or perhaps Lucina and Robin would just imply it afterwards. Or maybe Lucina would give Robin a pass. A pass to knead that round, curvy butt Severa inherited from her mother, whisper sweet nothings and pretend as if he was being seduced. Before he ruined that tight little pussy of hers. 

“I-Inside me… Lucina made the whisper a hiss in his ear. His final few thrusts were turned into slams, hilting his heavy cock inside her before he burst inside her. When he did so, Lucina squirted. She pushed her head against the wall and screamed, almost saying his name in the process. At the same time she heard a squeaky, high pitched mewl barely covered by a hand. 

“F–fuck… What is wrong with me… I’m no better than mother…

While the two were in the afterglow, kissing and basking in the warmth continually flooding into Lucina, Severa pulled sticky fingers out of her sodden cunt. All that sexy talk and practicing in front of the mirror, 

“You devil…” Lucina moaned. 

“Handsome devil.” Robin corrected before kissing her. Hot, slurry, and loving. “I think we better make up something to tell Severa. 

“Or maybe we could make it up to her.” Lucina added, with a hot gasp into Robin’s mouth he tasted faintly of vanilla with the sharp bite from the extract still on his lips “I always used to share my birthday cake with Severa as kids. I dont see why I can’t have that now…”
