“Oshi-san, are you okay? Ya’ look kinda down…” Mika asked, worry evident on his face. The aforementioned man was mindlessly playing with the food on his plate, something Mika had never seen him do. In fact, he got scolded for doing the exact same thing multiple times in the past. “Nnah, Naru-chan! Look at ‘im!”

Arashi sighed, reaching over to still the fork, poking and prodding at a slice of mostly uneaten cake. “Shu-kun, what’s wrong? You’ve been acting weird since we got here.” Once a gentle hand grasped his wrist, he was finally broken from the trance. The others could almost see the steam coming from his head.

“I've been meaning to ask, what do you two do on these ‘girls nights’ anyways?" He asked, nearly pouting as he let the ornate fork drop onto the plate. Arashi couldn’t believe her eyes—well, it wasn’t unlike Shu to get jealous, but this was downright adorable. 

So, that was it…he’s just feeling left out.’ She thought, and the glint in her eye was only noticeable to the boy in front of her—who was currently wide-eyed and stammering.

“Ah—uhm…nnah, Oshi-san, it’s jus’ like…a hangout?” He flushed, and Shu looked at him inquisitively, one perfect eyebrow raised. “I mean, depends if Ritsu-kun’s here or not anyways…” Arashi stifled a laugh, and Mika opted to shovel cake in his mouth before he embarrassed himself further.

“If you’re so curious, why don’t you join us?” She questioned, rubbing circles into his clothed forearm. He sputtered, ripping his arm away to rest in his lap.

“I don’t see why not,” He turned his head, signature light pink dusting his cheeks. “When is your next ‘hangout’ then?” Mika looked over at Arashi, panic written all over his face, but she simply smiled.

“How about tonight?”

——

The Starmony dorms were unnaturally quiet at night. Usually bustling and chaotic, there was always something of interest happening. But at night, when all that could be heard was the quiet chirping of cicadas (or a certain someones dorm causing a racket), mostly everyone was getting their beauty sleep. Which made it much easier for Shu to make his way towards Mika’s shared dorm without being interrupted.

Once he arrived, he knocked on the wooden door. It was unmistakable, even in the dark. The nameplate was decorated quite interestingly, stickers of bats and stuffed bears plastered all over. Still, he was surprised when the door opened, and instead of the usual lapis and amber greeting him like an excitable puppy, he was met with violet.

“Arashi. You arrived early.” He stated, confused but still giving her a small smile. She was guarding the door, making sure he couldn’t peek inside.

“I had to do some preparations.” They were both startled when a small, unmistakable whimper shot through the air. “…Want to come in, Shu-kun?” Her voice was a whisper, low and entrancing. He shivered, a wave traveling up his spine.

“Where’s Kagehira?” He questioned, trying to regain his footing. She smiled, devilish and knowing, and he couldn’t help but stumble again.

“Want me to show you?”

She grabbed his hand, slowly ushering him inside. The air was immediately different, heady and thick as he stepped through the doorway. Shu didn’t know what he was expecting to see—but the breath was punched out of his lungs upon seeing the boy on the bed. Completely bare, save for the maroon rope decorating his wrists. He was blindfolded, and Shu quickly recognized the cloth as one he had custom-made for their anniversary. His entire body was flushed, back arched with his desire, and when Shu’s gaze trailed down further, the sight was too much for him to bear. Still, he couldn’t look away, mouth agape as he stood frozen in place. Arashi laughed, closing his mouth for him with a gentle hand as she moved over to Mika.

“Poor thing…Sorry, Mika-chan, I know you don’t like being left alone. But guess what? Your Oshi-san’s here~” He whined, loud and needy, and the sound shot through Shu like a bullet. His head turned, searching for Shu as if he could see anything at all. “Look at that...He wants you, Shu-kun.” Her hand caressed Mika’s flushed cheek, searingly hot to the touch, her thumb playing with a plush lip. Shu’s mouth went dry, his heart felt as if it had jumped into his throat. It wasn’t something he hadn’t seen before, but seeing the two most beautiful people he knew beckoning him, calling for him…How could he be unaffected?

At some point, while deep in his trance, Arashi had crawled onto the bed. She had Mika displayed on her lap, lithe body all for Shu to take in. He was frail, but not as much as before; his jutting hips softened and ribcage not as noticeable. Arashi noticed his staring, and soon enough slender fingers were trailing the soft skin. Mika trembled against her touch, body reacting as if he hadn’t been touched in years. He was sensitive, on edge, and Shu wondered just how much preparation Arashi had done before he’d arrived. Her fingers eventually found his chest, she peppered kisses along a freckled shoulder as she teased the buds. He whimpered, arching his back and pushing his chest into her touch—closer to Shu. It’s like Mika’s body was calling for him, desperately begging for those elegant hands he loved so much.

Shu reached a shaky hand over, wanting to feel the warm flesh for himself, needing to feel the way his body shook at every gentle caress—but he was swiftly denied. Arashi smacked his hand away, and the shocked gasp Shu let out was enough to make her laugh; a cruel sound. 

“Did I say you could touch him?” She smiled, but her tone betrayed any air of sweetness she was trying to convey. Shu held his hand, too shocked to think of an answer, and simply shook his head. “That’s what I thought. Shu-kun just needs to watch for now, okay? Come on, Mika-chan. Let’s show him what we do on girls nights~” Their lips locked in a hungry kiss, one hand holding his jaw and the other rubbing circles into the dip of his waist. She kissed him like she was trying to devour him, eating up every little moan and whimper that spilled out of his lips.

Shu watched, took in every slight movement. Like how Mika desperately clung onto her, collapsed onto her chest, trying his best to anchor himself even with his hands tied. Or how every time her fingers landed on his chest his thighs would spread ever so slightly more, exposing his dripping cunt little by little and—gods, Shu couldn’t even look. The maroon fabric of the blindfold was growing darker, damp with sweet tears. Mika always cried so easily; he didn’t even have to be teased too much to have them rolling down his cheeks. It was jarring at first—neither of them wanted to hurt their precious Mika, of course (at least, in the normal sense). But soon enough, those same tears that worried them so much became a dark source of pleasure. 

“Mm, Shu-kun~” Arashi purred, snapping him back to reality. Her hand still gripped Mika’s jaw, his lips slick with their mixed spit. Then, both trailed down his body. Shu’s eyes were transfixed, staring intently as she firmly grasped his soft thighs, spreading them open slowly. Shu felt dizzy; he was so hard he feared the fabric of his pants would tear—but he couldn’t look away. He was wet, so so horribly wet, making a mess of the pristine bedsheets beneath him. Shu couldn’t get enough of it, he found himself leaning forward involuntarily, ever so slightly.

“Shu-kun~” Her hand rubbed circles onto his thigh, agonizingly close to where Mika needed her the most. He whined, hips twitching as if trying to push her closer. She laughed, breathy and quiet, before using two long fingers to spread open his cunt. Shu swallowed, lidded eyes staring as she put him fully on display for him. “Do you want to eat him out?” She asked sweetly, and Shu almost collapsed, limbs heavy with shock. He nodded, much too eager for his liking, and Arashi giggled, beckoning him forward.

“O-Oshi-san…” Mika whimpered, the first words he’d said that entire night. Shu crawled over, face burning with a potent mixture of desire and embarrassment, and placed a reassuring hand on the boy's trembling thigh. His face was so close, Mika could feel his breath, hot and heavy, agonizingly close to where he needed him. His hips twitched forward, and Arashi scolded him with a harsh slap to his pussy. Not enough to hurt too much—just a warning, but Mika cried out anyways.

“Go on, Shu-kun. He’s allll yours~” She teased, holding his thighs open with a bruising grip. Shu leaned forward, eyes fluttering closed as he kissed the soft flesh of the boy’s thighs. Nipping softly and trailing from upper-thigh to bony hip, and by the time that Shu met his destination, Mika was squirming and whining.

He placed a tentative lick on the seam, the taste flooding his tongue and forcing a groan out of him. Shu was no expert, he’d only done this a handful of times, but his partner’s taste was so intoxicating he feared he could get addicted. Mika cried—always so reactive—and that was enough to earn him another lick, bolder this time. Shu dipped his tongue into the folds, lapping up the sweet nectar, allowing it to drip down his chin. He held onto Mika’s thighs like a lifeline, lips closing around his clit and sucking harshly.

Everything was too much—Mika’s taste, his scent enveloping him, the downright lewd, wet noises. Not to mention the high whines that were ripped from Mika’s throat each time Shu’s tongue grazed his entrance. Far too much. Shu moaned, breathy and hot and gods he was close. So close and he hadn’t even been touched. The wet spot on his pants was extremely noticeable, but nothing could really get past Arashi’s sharp eyes. She grabbed Shu by his hair, pulling him off of Mika with a strength even he was shocked by.

“Shu-kun’s had his fun, it’s my turn~” She smiled, and all Shu could do was pant and attempt to recover any semblance of dignity. Which was extremely hard to do with your boyfriend’s cum dripping down your chin.

Arashi dipped her fingers past his folds, tracing circles and gathering the wetness before plunging inside. Mika nearly mewled, head thrown back against her chest as she fingered him, much too slow for his liking. First one, then two, three, four, until Mika was stuffed to the brim, pleads of ‘too much’ falling from his lips like a stream, the same as his tears. Arashi cooed, kissing his cheek lovingly as she fucked him, rubbing his clit with her thumb.

“Don’t worry, Mika-chan. I’ve got a surprise for you, okay? So we have to get you nice and prepped.” She reassured him, but the venom coating her tone only made him beg more. Arashi was a sadist; the three of them knew this very well. She could be gentle, try and disguise herself with sweet words and loving actions, but there was nothing she loved more than seeing her two adorable partners trembling beneath her, silently begging for her forgiveness. Luckily for her, Mika loved nothing more than pleasing his girlfriend, no matter what that might entail.

“Kagehira…” Shu whispered, a warning as he captured the boy in a kiss. Mika could taste himself on his tongue, and it made his head spin with desire. A heated reminder of how his Oshi-san had dirtied himself for him. The thought made him clench around Arashi’s fingers, whining pitifully. She slid each one out slowly, leaving him empty and desperate, breaking the kiss to cry out against Shu’s lips.

“Shu-kun, go and strip for me. I think it’s time we give Mika-chan our surprise~” She smiled, and Shu immediately started unbuttoning. He cursed himself for the shakiness of his hands, as well as the tiny buttons he had sewn on. As he fumbled with the zipper, Mika’s needy whine reverberated in his skull, and he whipped his head around to see Arashi’s cock pressed against his entrance. She sank in slowly, stretching his cunt to the point of breaking, licking the bead of sweat that ran down his exposed neck. Shu could only watch—his dick throbbing within the confines of his boxers—but Arashi hadn’t given him permission to touch yet. He flushed with the realization of his obedience.

“N-Naru-chan! Faster…please—I need—“ He cut himself off with a whine, drawn-out and needy as Arashi thrust into him once, deeper and harsher than any before it, right before going back to her original pace. He whimpered, shrinking into himself like a scolded puppy, not wanting to test her patience. He took it so well, shivering as her thick cock dragged against his sensitive walls, excruciatingly slow. 

“Mm…I think that’s enough prep. Shu-kun, come~” She beckoned, and Shu shuffled over, hands placed primly in his lap as he awaited her instructions. “I want you to fuck him with me, okay? Mika-chan, you can take both of us, right?” She asked, hardly a question and more like a direct order. Mika moaned at the mere thought of being filled so thoroughly by his two loves, squirming on Arashi’s cock, shoving it deeper with his excitement. Arashi giggled, petting the messy mop of black hair.

Shu couldn’t deny the potent arousal that tore through him at her words—but his concern couldn’t be ignored. Mika had proven to both of them how much he could take in the past—neither Shu’s nor Arashi’s punishments were anything to be taken lightly—yet, Shu was afraid this would truly break him. Shu’s size was…nothing truly impressive, but Arashi? Even Mika, with his various grotesque non-human ‘toys’, struggled to take her. Arashi must have sensed his apprehension, glancing up at him with a smile.

“Won’t he…break?” He cringed at the way his voice came out, broken and low from his uncharacteristic silence. Whenever Arashi was in charge, he preferred to be that way. Loved drifting into that fuzzy headspace, letting her take the reins. 

“Don’t worry, Mika-chan loves being broken~” Her fingers traced his puffy cunt, the redness of his stretched hole, and let one of her fingers slowly slip inside. Mika threw his head back, pink lips parted in a permanent ‘O’ shape. The noise that was strangled out of Mika’s throat was filthy, absolutely vulgar, and Shu was harder than he’d ever been in his life. “Aww, see, Shu-kun? He’s ready for you.”

Arashi pumped her finger in and out a few times before removing it, reveling in the whimper Mika let out, as if he couldn’t handle not being stuffed to the brim for more than a millisecond. She stroked his cheek soothingly, damp with tears, and he nuzzled into it instinctively—her heart almost burst at the sight. Arashi maneuvered Mika so that he was on top of Shu’s chest, hands clinging desperately to him for support, and she lifted his hips so that Shu’s cock pressed firmly against his entrance.

It felt impossible—it surely was impossible. But Mika was always so good for them, always doing his absolute best, always being obedient, no matter the unreasonable or humiliating request. So, by some miracle, and with Arashi’s firm grip on his hips, Mika lowered himself down onto Shu’s cock. He sobbed as he was filled, arms shaking with such intensity Shu feared they would snap right off. But, the mind-melting heat and tightness enveloping him were enough to render him thoughtless for a moment. Mika sunk down until he physically couldn’t take anymore inside, his upper half collapsing onto Shu’s chest as he clenched and convulsed, breath uneven and choppy. 

“Mika-chan, did you just come? Guess we teased you a bit too much, didn’t we?” She giggled, grip tightening as she ground harshly, so deep inside he swore he could feel it in his skull. “Sorry, but hold on a little longer for us. You can, right? Such a good boy~” Arashi praised, moving her hips slowly so as not to completely overwhelm him at first. She could be gentle, only when she wanted to be. She dragged out, feeling Mika clench down involuntarily as he nearly screamed, hands clawing desperately at Shu’s chest.

Shu swore—closing his eyes to focus all of his energy on not coming immediately. Mika was excruciatingly tight, and the sensation of Arashi’s cock rubbing against his was too much to bear. Mika was so close to him, so incredibly close. They were face-to-face, and he could almost swallow Mika’s moans as they dripped out of him like honey—sweet and addicting. He wanted, needed more. He thrust up, trying his best to match Arashi’s speed exactly. A perfectionist even in moments such as these. The cry that tore out of Mika was enough to keep him going, wanting to drag this out as long as possible.

Mika felt like he’d been split in half, he was so full he couldn’t think about anything else. His already cotton-filled head was stuffed, full of nothing but pleasure and the mind-numbing pain of being stretched to his limits. He’d already come once, and his body and mind were torn; the pleasure was all-encompassing, bordering on tortuous, but he didn’t want to escape from it.

“N-Naru—! Oshi—nnh…! Please? P-please!” He babbled on, helplessly confused and unsure of what he was even pleading for. But he begged nonetheless. Shu leaned forward, capturing Mika in a kiss, hasty and eager, like Mika would slip through his fingers. Arashi sped up her pace, fingers digging into Mika’s sides with brushing strength. He sobbed, a broken and melodic song, and Shu quickly kissed him again, greedily licking it up. He couldn’t help it; it felt animalistic—the surge of possession that ran through him. A shaky hand reached up to card through messy hair, gripping the strands at the nape of his neck.

They separated after what seemed like eons, and—oh no. Mika’s blindfold slipped off, revealing tear-filled lapis and amber eyes. Pupils blown out, darkening them to an impossible degree, his eyelashes were damp with tears that spilled down his flushed cheeks. Their eyes met, and immediately Shu was gone. With a gasping moan, he spilled deep within Mika, hips twitching up a few more times before stilling completely.

Arashi laughed, cruel and beautiful as Shu slipped out, cum dripping out of Mika’s pussy and onto Shu’s stomach. He heaved, arm thrown over his face to shield his unsightly expression.

“My, Shu-kun. That was faster than—ah!—usual…” She teased through groans, pretty and soft even as she increased her pace, fucking up into Mika so roughly his vision went white. Arashi pressed into him, caging him against her chest as she licked and bit at his shoulder. His eyes were unfocused, and he blinked blearily as if he didn’t even know where he was.

“I’ve got you, Mika-chan. G-god…just a little more okay?” She gasped, burying her face in the slope of his neck. Mika whimpered as her cock slammed cruelly against his spot, back arched like a bow, ready to snap at any moment. It had been mere minutes since Shu had come, but the sight above him—the two most beautiful people he knew, disheveled and unraveling above him—was enough to get his dick twitching with interest again. 

“Nnh—thank ya’ N-Naru-chan..! T-thank ya thankyathankya—“ He sobbed, making sure to show his gratitude as he came, body collapsing in Arashi’s arms as he rode out the intense waves of his orgasm. Arashi was right behind him, coming deep inside with a shaky moan.

They sat for a moment, trying to regain their breath. Arashi kissed Mika’s neck soothingly as she pulled out, there mixed cum almost pouring out of him. Shu watched with wide eyes as Arashi gathered it on her fingers and fucked it right back into Mika’s messy, used cunt. He squirmed, whimpering and mewling pathetically, trying to escape her grasp. She decided to grant him mercy after a few moments, slipping her fingers out and bringing them to his mouth to let him suck the filth off. It was lewd, obscene—possibly more than anything he’d seen so far that night—but he couldn’t take his eyes off of it. 

Shu languidly stroked himself to the sight; Mika choking on Arashi’s long fingers as he greedily licked up the cum, fat tears rolling down his cheeks. “Oh my, hard again, Shu-kun? You’re so easy~” She cooed, jerking Mika forward and onto his stomach roughly, so Shu’s dick was pressed against his cheek. “I think Mika-chan deserves a reward, don’t you?” 

Shu would’ve responded, but every attempted word died in his throat as he stared down at Mika. Pre-cum stained his cheek as he pathetically attempted to take his cock into his mouth, hands still bound behind his back. Once the tip finally found its way past his kiss-bruised lips, Mika eagerly began to suck, like it was a piece of his favorite candy. Shu gasped, bucking his hips up and forcing more of his cock down Mika’s throat. He choked, but quickly recovered, slowly taking the rest into his mouth, until the tip nudged the back of his throat. Mika glanced up at him, looking way too innocent for someone with a cock down his throat, and the image forced Shu to close his eyes.

Mika began bobbing his head, taking his length fully with little effort. He was in a daze, pleasure-drunk and focused on one thing alone—tasting more of his Oshi-san’s cum. 

“M-Mika!” Shu gasped, grasping his hair and using it as leverage to fuck deep into his throat. Mika hummed happily, staring up at Shu the whole time, only breaking to blink away the tears filling his eyes. Soon enough, Arashi dragged Mika off of Shu’s cock, not without a pained whine from the aforementioned, of course.

“Don’t worry, Mika-chan. I just want to play with him a little, alright?” She reassured, repositioning them so that Shu rested comfortably in her lap, back pressed against her chest. 

“Ready for me, Shu-kun?” She prepared him, fingers rubbing at his hips, running up and down the impossibly soft skin of his thighs. Shu shook his head—both of them knew that it took a lot of preparation for Shu to take Arashi. He wasn’t a pro like Mika, and hadn’t had nearly as much…’solo experience’ before this. She laughed, and he felt the rumble against his back. 

“I know, I know. How about my fingers?” She questioned, already knowing his answer as she reached for the lube. Shu nodded, and she smiled. “It’s rude not to respond, you know? Tell me you want me to finger you, Shu-kun~” Shu flushed down to his shoulders, closing his eyes and taking a deep breath.

“I-I want…your fingers.” He muttered, nearly a whisper, but thankfully, for his pride, it was good enough for her. She traced his entrance with one elegant finger, slowly pressing in. Shu shook—it was still a foreign sensation to him, but definitely not unwelcome. She pumped the digit in and out, adding a second when she deemed him relaxed enough. Shu gasped, sweet and breathy, and Mika kissed his thigh from his place on the bed. 

She fucked him gently, crooking her fingers in search of that special spot inside of him, and she knew she’d found it by the strangled moan the man let out. After that, she was relentless. She pressed onto it with the pads of her fingers, massaging it at a speed so tauntingly slow that Shu would almost call this a punishment; that is, if he hadn’t experienced those firsthand. He slapped a hand over his mouth to stifle the broken moan that threatened to spill out, the embarrassment was already overwhelming enough. Every press against his walls felt electric, traveling up each of his vertebrae one by one until it reached his skull.

“Shu-kun, are you close? Come on, give Mika-chan his treat~” She whispered, breath hot against his ear as she reached down to roughly pump his cock in her hand. When he looked down—always a mistake—Mika was waiting patiently, mouth open and tongue lolled out, hazy eyes looking straight up at the two of them with such devotion and love that he couldn’t hold it anymore. Shu came with a whimper, cum spilling all over Mika’s face, a good portion falling onto his tongue, which he swallowed happily.

Arashi allowed him to rest for a moment before slipping her fingers out, not wanting to overstimulate him any further. She peppered his damp neck with soft kisses, maneuvering him off of her lap and onto the mountain of soft pillows awaiting all of them. She pulled Mika close, pulling on the quick-release knot and rubbing at his reddened, sore wrists. Mika never minded the burn from the rope, it served as a nice reminder until their next session—or, that’s what he had sheepishly confessed to her.

“Goodness…I really did a number on you two.” She sighed, brushing their bangs to the side and placing a kiss on the center of their foreheads. 

“Mm…but it w’s real nice, Naru-chan…ya’ spoiled me tonight. Both of ya’ did.” Mika grinned, toothy and wide. Arashi couldn’t help but smile too, falling back onto the pillows and closing her eyes.

“So, Shu-kun. Wanna come to girl’s night again soon?” She teased, and Shu huffed, embarrassment apparent even in his noises.

“I suppose, I don’t see why not. As long as I’m being invited…” He flushed, and Mika giggled, turning over to muzzle his face against Shu’s chest.

“Course ya’ are, Oshi-san!”

“Goodness! Would you get off of me? You’re absolutely filthy. I won’t have you touching me until you’ve had a thorough bath—all of us.” He practically screeched, and Mika giggled, rolling off of him.

“Alright, let’s go get cleaned up. Mika-chan, you especially.” Arashi grimaced at the dried…substances on Mika’s face, getting out of bed and walking towards their bathroom.

“Mm! But, uh, I dunno if I can walk anymore.”
