"Aaaah~ Just what I needed!". Exclaimed Nino, stretching her arms back as she enjoyed the salty sea breeze against her damp skin after playing in the sea for a while.
Next to her, her two high school friends, Otori and Yamada, who were drying themselves with towels, certainly had a hard time sharing her enthusiasm. What was the reason for this? Well...
"Hey..." Yamada called out to Nino. "What the hell are you wearing?"
"A swimsuit, duh." The second quintuplet looked at her with one hand on her hip, flicking her hair back as she saw the girl looking her up and down.
Nino's voluptuous breasts were encased in a black top with some white sports straps that tied in the center with a lace, covering only what was necessary, bouncing with every step she took on the sand. If that looked obscene, the bottom was completely horrible: a Brazilian thong whose straps rose above her hips, practically revealing that Nino had completely shaved the night before. Oh, of course, let's not forget the thigh-high stockings that squeezed her thighs, as if it wasn't already obvious enough how much juicy flesh this girl had to offer.
"We know you're proud of your body, but we still have to ask: why?" At her side, Otori raised an eyebrow.
"Because I know Fuu-kun is going to be around and I want him to look at me" she replied casually, irritating Yamada.
"Just him or the whole damn beach?" she growled, staring at her friend's impressive golden valley before lowering her gaze to her own with a shadow over her eyes.
Otori, although he didn't care as much as the brown-haired girl, couldn't help but do the same. Realizing that, of the three, he was in last place.
"I used to think ruffles on swimsuits were cute, now I feel like a little kid wearing them..." she said with comical tears welling up in her eyes as she used the towel hanging around her neck to further cover her miseries.
At Yamada's comment, Nino scanned her surroundings. Wow, it seemed she was indeed attracting attention, especially from the boys in the class who had come on this outing they had organized to celebrate that no one had failed any exams. They were practically devouring her with their eyes, drooling like hungry wolves. Well, she certainly didn't mind the attention. Not because she was a slut or anything like that, at least not that kind.
"Humph, well, I hope they enjoy the view and jerk off in they rooms, because I already belong to someone else," she said in a haughty tone that made her friends sweat, taking the lead of the group to go take a quick shower in the sauna.
"I'd like to say she's stuck-up... but I can't help feeling that I admire her self-confidence," Otori murmured to Yamada, smiling slightly.
"Yeah, she's been like that since we met her in 2nd grade, right? I guess I like that about her too, she's taught me a lot." She agreed with the sentiment.
However, her frown from a moment ago returned with greater intensity as she looked down and noticed Nino's slight swaying of her hips, watching the girl stick a finger into her backside to pull out the fabric of her thong that had gotten too far between her buttocks.
"But even so, that doesn't change the fact that she needs to be taught a lesson..." She gritted her teeth, clenching her fist until her knuckles turned white.
"Yamada-chan?" Otori was puzzled by the sudden attitude, narrowing her eyes at her companion. "What are you going to do?"
"You'll see~."
The black-haired girl was more than willing to intervene if she was planning something that would threaten Nino's safety, but upon hearing her generic villainous laugh, she relaxed, knowing that it would probably be something silly.
(...)
The air inside the sauna was thick, a hot mist that enveloped every cedar wood surface and clung to the skin like a second layer of sweat. The trio of friends lay on the upper benches, wrapped only in thin white towels that the steam made translucent in places. The silence was comfortable, broken only by the hiss of the red-hot stones as they received a ladle of water courtesy of Nino.
The second sister, her eyes closed, let out a sigh of satisfaction as she allowed the heat to penetrate her muscles. A nice contrast to the cold sea water.
Seeing that the situation had settled down, Yamada got down to work (literally).
"Haa~." Without any pretense, Yamada untied the knot of her towel that covered her silhouette, letting it fall from her shoulders so that it was all rolled up on the wooden bench where they were sitting.
"What are you doing?" asked Nino, looking at her strangely, as did Otori.
"What? So the steam will penetrate the skin better. It feels better!" she said in a relaxed tone. "You should try it."
"Yeah... no. I'm fine like this" Otori refused, paying attention to see how this would unfold.
"What about you, Nino-chan?"
"Ugh, I don't know. We've seen each other in the school locker rooms, but never, you know, completely naked..."
"Come on, it's just us, so it's no big deal, right?" Yamada stretched her legs, looking, ironically, completely cool in her natural state.
Well... Nino wasn't going to deny that the offer had its appeal. Besides, the towel was starting to weigh her down.
"Okay, you win." With a nimble movement, Nino imitated Yamada, discarding her towel and throwing it aside. She couldn't help but let out a small groan at the noticeable change this brought, especially when her body received another dose of warm steam as Otori rekindled the rock, now impacting every part of her existence, especially in the corners of her groin and the corner under her chest.
"U-Ufff, yes... you're right, this feels much better." She murmured without opening her eyes. Throwing her head back, the butterfly girl enjoyed this change before feeling Yamada move closer to her and wrap her arm around her shoulder to hug her.
"What are you doing now?"
"No, nothing~ I just wanted to get more comfortable."
She probably would have believed that and let it go if it weren't for the fact that her hand began to slide down her waist. The almost blonde girl, with slow movements, began to trace silky circles on the quintuplet's skin. Nino was quite clingy with her friends, and she really had no problem with physical contact, so once again, she would have let it go if it weren't for the deliberate slowness and intensity with which her fingers began to venture down her thighs.
Oh, of course, not to mention that they were both completely naked.
"Yamada?" Nino opened her eyes again, this time with a flash of alertness. A blush, which was not just from the heat, began to rise up her neck.
"It's just that your skin is so soft here, Nino-chan." She replied in a voice as sweet as poisoned honey as her middle finger navigated the crease of her V-zone, which was practically a direct rail to an area so private that its owner let out a muffled gasp from its mere proximity.
"Uhmgh..." Nino frowned as the girl practically pressed her body against hers, her heavy breath directly on her neck. She knew what was going to happen, it was so terribly obvious, but despite her best efforts to maintain a dignified attitude, she still let out a sharp moan when her breasts were captured by her hands.
"Aah!~."
"Wow, now I understand why all the boys stare at them." She teased, kneading them hard like stress balls. Now she understood why the class representative had seemed more relaxed lately.
"I-Idiot... that's enough, don't you think?" Nino growled.
"So this is what you were up to? Pervert..." Otori was red with indignation.
"Are you joining in or are you just going to stand there watching?" She asked defiantly, glancing quickly at Nino's assets, letting her know what she was really offering.
"Nino?" Otori wanted to know her opinion on the situation. She just sighed.
"The only reason I haven't smashed both your faces in is because... ugh, how do guys usually say it? Between friends it doesn't count or something?"
Oh yeah, Otori and Yamada had heard about that. The rule was that it supposedly this didn't count as long as there was no kissing or holding hands, although they were pretty sure the boys only said that as a stupid joke to annoy each other and not to actually do anything gay.
"Besides, I'm not going to lie. I'm a little horny from wearing that swimsuit...I mean, who would refuse to be masturbated for free?".
"Thanks for reminding me why I'm doing this. Damn big tits..." Yamada muttered, annoyed.
"Bah, what the hell? For the sake of the story". Otori said with a shrug, matching Yamada's closeness to Nino.
The brunette smiled, releasing the breast on her side to give her control and kneading. The black-haired girl swallowed when her palm pricked her hardened nipple.
"On the count of three, Otori, ready?"
"What the-?"
"1...2...3!"
Before she could react, Nino instinctively had to clench her teeth when she felt a sudden moist warmth enveloping the pink crowns of both breasts.
"Mmghm!" She grimaced, looking down to see Otori and Yamada sucking on her nipples like a pair of babies. How focused they were on their own business created differences that made everything more obscene.
Yamada seemed the most enthusiastic, sucking and nibbling on her nipple, pulling her toward her before letting go and repeating the process, while on the other side, Otori was more cautious. For God's sake, two teenagers with access to the Internet already knew what to do, but the black-haired girl still limited herself to playing with her nipple with her tongue before enveloping the pink areola every so often.
"Fuu...aah~ mmh~." Nino tried to keep her moans under control, remembering that they were still in a public area, as were her friends, who took care to muffle the sexual sounds of their sucking when they heard voices passing by the dressing room outside. However, the task of keeping a low profile became increasingly difficult when two hands slid down her sides to begin taking care of her crotch.
"Ahh...Mmmgghn!" She pursed her lips into a line when she felt her friends' fingers caressing her slit at the same time. While Otori assaulted her clitoris, Yamada slid a middle finger in and out of her pussy, which was now soaked not only from the steam of the sauna.
"Until I cum... u-understand?" They heard Nino snap. "When that happens, it's over."
It sounded fair enough, and it didn't seem like it would take that long with Nino's added effort as she began to rock her hips back and forth, adding another layer of pleasure.
Yep, she definitely seemed to be getting closer and closer to her limit, especially considering that Otori had bent down to put her face between her thighs, replacing her finger with her tongue.
"Ooh, my fucking g-god...!" Cunnilingus was an operation that required expertise, and of course, it was difficult to find a girl who knew how to do it even though she hadn't even had her first time, but the mere fact of being licked down there was more than enough to please Nino in these circumstances.
"F-Fuck...a-aaahmmgh~!" After a while, it finally happened. With a particularly strong suction on the second sister's breast, which was undoubtedly intended to extract some breast milk, and a thrust of her tongue that grazed her vaginal canal, Nino reached climax, cumming directly into Otori's mouth and face while a contortion of her back rubbed her cleavage against Yamada's face.
Remaining tense for several seconds until it passed, the girl allowed her spine to relax.
"U-Ufff...haa...haa...wow."
As agreed, Yamada and Otori sat up, sitting back down on either side of a trembling and panting Nino as if nothing had happened.
"I'm sorry, Otori..." Nino apologized, trying to catch her breath as she watched the girl wipe her cheeks with the dampness of her towel.
"E-Everything's cool, don´t worry" she murmured, blushing.
"I hope that teaches you not to get so full of yourself! Hmph!" Yamada's pseudo-tsundere exclaimed with a smug expression, turning up her nose with a snort.
"Yeah, well... I don't feel very motivated to change my behavior, to be honest." She said, wiping the sweat from her forehead, massaging her pussy herself to make sure there wouldn't be another spasm from her orgasm that she hadn't yet received.
"Tsk, damn it. It was worth a try."
"Well, um... thanks? I guess? But we'd better leave before we raise suspicion about what happened here," said Nino, clearing her throat after so much involuntary noise on her part, moving to peel her buttocks off the seat surface and re-tie the towel around her body, receiving a nod of agreement.
"Yeah, let's go" Otori said, scooping some hot water from a nearby bucket with a ladle to pour it over the seat and floor, diluting Nino's squirt and disinfecting the crime scene.
"Right, I remember the guys saying a safe word for these situations. What was it? Oh yeah, 'No homo.'"
"No homo."
"No homo."
Ladies' education above all else.
However, even though it was all over, once they left the sauna and went to their lockers in the dressing room to put on their yukatas, Nino couldn't help but feel guilty. I mean, Ichika used to kiss girls all the time because of her job, and this was almost the same thing, right? Yeah, that didn't convince anyone.
She could be many things, but an NTR practitioner wasn't one of them, so tying the belt of her yukata, Nino went to find Fuutarou, really wanting to be mounted right now, or maybe her mounting him? Well, it was the same thing.
