"Oh, this is going to be SO much fun!"

Positively cackling, Nero laces her hands back behind her head as she continues to lead Mash down to the beach, a big, shit-eating grin on her face. Meanwhile, Mash follows behind her, letting out a quiet little sigh and keeping her head down. Internally, however, the demiservant is lamenting that her Master got suckered into playing a card game with Nero of all people. With A-Rank Luck, Goblet of Wealth, AND Imperial Privilege, there was absolutely no way that that game was fair.

Ah, but Lady Ritsuka, Mash's beloved Senpai and the woman who was Master of Chaldea, wasn't the kind of person who welched on her debts. Nero had won the right to order Mash around for the afternoon during the course of her card game with Ritsuka, and thus here Mash was, stuck with Nero until the sun had set and the day had come to a close.

As they reach the beach in record time, an order comes from Nero that Mash has been expecting (and dreading) since they left.

"Go ahead, Mash! Take off that jacket! Show some pride in showing off that body of yours~"

Blushing furiously, Mash slowly does so, even as Nero removes her own jacket far more jubilantly. Mash doesn't feel a single iota of pride in her body as she exposes the incredibly slutty sling-bikini that Nero had picked out for her to wear to the beach. It's embarrassing the way that only her nipples and slit are covered by the small, technical one-piece bathing suit. The rest of her breasts and crotch and ass are fully exposed, leaving her feeling just… incredibly embarrassed.

Nero, meanwhile, is wearing a two piece bikini, the top of which is barely more than a strap of cloth in it's own right, hiding away her nipples but not even trying to contain the rest of her barely held-in breasts. Dressed as they are, the two girls immediately attract a lot of attention, mostly from the male gender.

Eyes zero in on the two beauties as they move further onto the crowded beach, causing Mash to shrink in on herself, even as Nero enjoys the attention and struts her stuff. However, seeing Mash's behavior, the Empress stops and taps a finger against her lips for a moment… before spotting a group of men, likely friends, all openly staring at her companion.

"Hey, Mash. See those guys over there?"

"Y-Yes?"

"… Show 'em your tits!"

For a moment, Mash freezes, wide-eyed and mouth agape. There's a protest on the edge of her tongue… but it never leaves her lips. She won't insult Senpai's honor by disobeying Nero. She won't do damage to Lady Ritsuka's reputation by being a disobedient servant, even if she is just a demiservant! And so, as embarrassed as Mash is… she reaches up and quickly pulls open her sling bikini, exposing her cute little pink nipples to the men… and more of the watching crowd than she probably intended.

There are whoops and cheers from the group of men as Mash hastily covers up again, having completed Nero's order, but from the crowd itself, there are some… fairly derisive comments.

"Jeez, can you believe those girls? The beach isn't just a place to act like sluts…"

"Really, it's perverted bitches like them that give the rest of us women bad names. Like, now we'll be expected to be depraved cunts as well, despite just coming to the beach to relax and do a little sunbathing."

The women who's words manage to reach Mash's ear don't even look all that put out, and Mash can easily tell from experience borne of being a target for bullying that they're just saying those things to be mean, not because they actually believe they'll be expected to flash men now or something.

Quite pleased with Mash's submissive obedience, Nero leads her over to an empty spot of the beach and the two settle down for the Empress' planned afternoon of sunbathing. While nobody approaches them outright, there is a bit of a crowd that seems to follow them, along with some people who were already there when they arrived and refuse to move… or stop staring.

As Nero enjoys soaking up the sunbeams coming down upon her august self and the attention of the crowd as well, Mash is far more embarrassed by what's happening. It's impossible to relax as she feels the eyes of so many different people upon her, but any time that her fingers start to twitch towards her jacket, Nero forbids her from covering up without even looking in her direction.

Of course, news of two scantily clad bombshell babes soon spreads across the beach, with Mash being the first one to notice the amount of people around them steadily increasing. Whimper just a little, the demiservant reaches over and tugs Nero's arm, leaning in close and whispering to her.

"N-Nero… we're s-surrounded…"

She expects the Roman Empress to do something about it, to scare them all away. This is starting to feel a little dangerous, after all. Even if they might be strong enough to deal with all of these people, they probably couldn't do it without causing civilian casualties. Surely, a woman used to leading like Nero would be able to see that and would do the smart thing.

Which is why Mash is so shocked by what Nero does next. Opening her eyes, the Empress looks around, smiles wickedly, and then stands up. But rather than intimidating the 'peasants' all around them into leaving them alone… Nero takes off her swimsuit, stripping naked right then and there! Mash immediately leaps to her feet as well, mouth agape again in surprise and horror.

"Nero! W-What are you doing?!"

Grinning wickedly, the blonde plants her hands on her hips and gives Mash a conspiratorial wink.

"We owe it to our audience to put on a good show, Mash! C'mon, get out of that silly thing, not like it covers you up much anyways!"

There are some murmurs of agreement, mostly from men, that come from the crowd at that. Mash blushes and fidgets and squirms, knowing that she's supposed to do what Nero says, but nevertheless reluctant to do so. In the end, before she can psyche herself up for it, Nero takes the choice away from her altogether, reaching over and ripping the sling bikini from Mash's body, causing her to yelp and hide her bouncing jiggling tits and her slit.

Nero… Nero doesn't hide anything. Noticeably aroused and quite wet d-down there, Nero lays back down on her towel, this time face first. With her ass swaying in the air, it's quite obvious that she's waiting for the first man brave enough to come and claim her in front of everyone else on the beach. Mash… Mash wants nothing more than to run away crying, but also knows she's not allowed to.

Instead, the shy demiservant sits down next to Nero, acutely away of just how exposed she is right now… but also acutely aware of just how turned on she is by being seen by everyone. Yes, it's embarrassing. Yes, it's humiliating. But it's even more embarrassing and humiliating because of how AROUSING this all is. Mash… Mash really is a pervert, and she hates that part of herself. Unfortunately, Nero is forcing her to confront it in the most brazen manner possible.

Finally, someone moves forward and gropes Nero's gorgeous ass with both hands. When the blonde lets out a moan of pleasure, the man takes it as a sign to go further and has his rock hard cock out of his trunks and inside of Nero in seconds. As he penetrates her, Nero moans again, her arms stretched out in front of her as she pushes her hips back into his rapidly thrusting cock. Smirking easily, the arrogant Empress speaks up amidst her moans.

"Mmm~ You're lucky, you know! So incredibly lucky that you get to fuck me, your Empress. A-Ah, don't stop now! Give it to me long and hard, show me what you're capable of! Impress me, peas-mmph!"

Mash can only watch with wide eyes as a second man suddenly comes up in front of Nero and shuts her up in the middle of her speech, forcing his cock into her mouth and even having the audacity to grab her by the hair and pull her down his length.

"If you're gonna run that mouth of yours, slut, you might as well be sucking my cock instead…"

The craziest thing to Mash is that Nero seems to agree, moaning around his member and humming along his length as she slurps and sucks his dick. It's… it's madness is what it is, but it's the kind of madness that Mash just can't escape from.

Caught up in the moment, the young demiservant ends up masturbating to Nero's spit-roast as the two men going to town on the Empress fuck her hard between their dicks. As such, she's even more hopelessly turned on then before when a guy closer to Mash's age suddenly comes up to her and whips his dick out, leaving it hovering inches from her face.

"Hey, bitch… I wanna fuck your slutty tits."

His crude manner of speaking makes Mash blush and squirm, but as if in a daze, the demiservant nevertheless moves forward as if in a daze, taking his cock between her breasts and wrapping them around his length. She whimpers a little as she watches the tip of his dick slide up out of her cleavage again and again, back and forth. Mash really has no clue how long the titjob lasts, but after what's probably only a few minutes, he suddenly withdraws from her tits, only to pull her head close by her hair and jerk off his load all over her face.

Covered in cum, Mash can't help but finger herself to the humiliation of being jizzed on in front of an entire crowd. Shamefully, it's enough to send her right over the edge, and she orgasms in front of EVERYONE. Her eyes drift shut for a moment in ecstatic bliss, and the entire world seems to fall away, save for the noises Nero is making as she gets fucked in both ends.

When she recovers enough to open her eyes again, it's to find quite a few men surrounding her, even cutting off her view of Nero as she stares up at them all and their big, hard cocks. To Mash's mild surprise… she finds that she's actually looking forward to servicing every last one of them. Licking her cum-covered lips, the perverted demiservant gets to her knees and reaches out, taking a cock apiece in her hands as she swallows the one directly in front of her whole, up until another guy takes her by her hair and yanks her over to HIS cock, demanding satisfaction as well.

It's a proper blowbang as her slutty mouth is directed to dick after dick, hands feeling up her naked breasts even as her own hands stroke and jerk off the cocks surrounding her. Things are only going to escalate from here, Mash can tell… and honestly, she can't wait.

-x-X-x-

"Whoa, that's a big crowd!"

"Yeah, that's where those two sluts are! You can take pictures and stuff and they don't even CARE, haha!"

As the two newest men join the crowd surrounding Nero and Mash, the two women in question… aren't even really aware that their audience just got bigger. Surrounded on all sides, they're not really aware of anything or anyone except for the cocks being presented to them or stuffed into their holes. Both are bouncing up and down on a dick apiece at this point, while choking on another cock, jerking off two more on either side, and also taking a phallus apiece up their ass for good measure as well.

Both girls are ahegaoing beautifully as they take dick after dick, and even the arrogant Empress that Nero is has been stripped away completely by this point, her attitude discarded in favor of getting more cock and cum inside of her and upon her body. Meanwhile, Mash has… completely given in to her desires by this point. If she were at all coherent, perhaps she would have stopped to wonder just how Nero had sussed out precisely what her particular perversions were, but Mash is in no state to be contemplating such things at the moment.

All that matters is the dick in front of her, the dicks to the sides of her, the dicks in her cunt and ass. All that matters is the pleasure as she gets fucked nice and hard by guy after guy there on the beach.

-x-X-x-

As the sun sets and Nero's claim over Mash expires, neither of them are paying much mind to that fact. They're both too busy pressing their cheeks together, tilting their heads back, and opening their mouths nice and wide to loll out their tongues as the final degenerate on the beach cums all over their slutty little faces. Groaning wantonly, he finishes all across their chests for good measure as well, and then tucks his dick back into his swim trunks and staggers away.

Relying on one another for support, the two end up leaning against each other as they limp back to the hotel where the rest of the Chaldea vacation team is hanging out. Their swimsuits are long gone of course, and so are their towels and jackets, so the two girls end up walking through the streets with nothing more than cum splattering their bodies and pleased, satisfied expressions gracing their faces.

"You know, an afternoon gangbang like that one was usually just a warmup for me, back when I was still alive. Hehe, I once got fucked for three days straight in my theater after I boasted that I could pleasure every man in my Legions without needing a single break."

Mash blushes at that… and then asks the obvious.

"D-Did you succeed."

Smirking, Nero side-eyes her and licks her lips suggestively like the man-eater she is.

"What do YOU think?"

Rather than blush and duck her head in shyness, Mash still blushes… but also giggles a little, very much cum drunk at this point. Soon enough, they're back at the hotel and Nero is dropping Mash back at Ritsuka's room. As soon as her Senpai sees her, the Master of Chaldea has a big grin on her face, giving Nero an appreciative nod and pulling Mash towards the bathroom as a hand wanders down to Mash's ass and gropes her while they walk.

Nero, considering her job well done, smugly begins to make her way back to her own room… grabbing onto a surprised hunky passerby as she does and pulling him along after her. After all, the night is still young… and the Empress is not QUITE fully satisfied yet.
