Who’s got the biggest dick? Foursome w/ Higuruma, Nanami & Kusakabe
cw: explicit, M/M/M/F foursome, double penetration, aphrodisiac use, three guys fighting over who gets to make you come next.
Foursome Definition: It’s the visual and physical opposite of the clean, linear Eiffel Tower: instead of a simple line, it’s a dense, sweaty, multi-layered pile where you’re in the center, completely surrounded and filled with cock from all angles at once.
It’s another Friday, 9 PM. The four of you are sprawled around Nanami’s living room—his low table covered in takeout containers, fairy lights strung up because you insisted last month it “makes the vibe less depressing.” The TV’s on some mindless action flick nobody’s watching.
You’re in the middle of the couch between a slouched Kusakabe, already on his third beer and Higuruma still clocked in reading case files. Nanami’s across from you on the armchair, still in his dress shirt.
The conversation drifts, as it always does, to dumb shit. Kusakabe smirks, holding up a small foil packet like it’s contraband. “Yo. Remember that gas station in Shinjuku? They had these honey packs behind the counter. ‘Royal Honey VIP’ or some bullshit. Said it makes you go all night.”
Higuruma doesn’t even look up. “You bought aphrodisiacs from a konbini. Classy.”
“Four of ’em,” Kusakabe says proudly, tossing packets to each of you. “One for everybody. C’monn I just wanna see if it even does anything, but I doubt it will. Might as well test the theory.”
Nanami makes a long-suffering sigh of a man who’s spent two decades corralling these idiots—but he catches his anyway. “This is idiotic.”
You laugh, turning yours over. “Come on, Kento. Live a little. We’ve done stupider things.” He meets your eyes. “Fine. But if I end up in the ER, I’m billing all of you.”
They all rip theirs open at the same time. Thick, sweet honey squeezed onto tongues. It tastes like expensive cough syrup, fucking disgusting.
You’re still sandwiched between Kusakabe and Higuruma on the couch, legs kicked up across Kusakabe’s lap because he claimed “more room” like an asshole. Nanami’s back in the armchair, shirt mostly open now, one ankle crossed over his knee.
“Man,” he drawls, scratching lazily at his stomach under his shirt, “this shit’s hitting different. I feel like I could bench-press a car. Or fuck through a wall.”
You snort. “Romantic.”
Higuruma doesn’t look up from where he’s idly swirling the last of his beer. “You already talk like you could fuck through a wall on a normal Tuesday.”
“Jealousy’s a bad look on you, Hiromi,” Kusakabe fires back, grinning wide. He stretches, arms over the back of the couch, deliberately crowding you more. His thigh presses hot against yours. “But seriously. You guys ever think about how unfair dick genetics are?”
Nanami raises one perfect eyebrow. “We’re doing this now?” “We’re absolutely doing this now,” you say, grinning as you nudge Kusakabe with your elbow. “Go on. Enlighten us.”
Kusakabe takes the invitation to brag. “Look—I’m just saying some of us got blessed, some of us got… adequate.” He side-eyes Higuruma. “No offense.”
Higuruma finally sets the beer down. “None taken. I’ve never had complaints.”
“Exactly,” Kusakabe says, pointing at him like he’s making a winning argument. “You’re long. Elegant. Lawyer dick. Probably slides in like butter. Me? I gotta do warm-up drills.”
You laugh so hard your head tips back against the couch. “Warm-up drills?”
“Yeah. Foreplay for like twenty minutes minimum or it’s game over. Girls either tap out or cry—happy tears, obviously.” He waggles his eyebrows. “Big-dick problems.”
Nanami pinches the bridge of his nose. “You’re insufferable.”
“You love me,” Kusakabe says cheerfully. Then he turns to you, suddenly conspiratorial. “C’mon, princess. You’ve seen all of us change in locker rooms and shit back in the day. Be honest. Scale of one to ‘monster cock,’ where we ranking?”
You pretend to think, tapping your chin. “I think Hiromi’s got length—like, porn-star proportions. Kento is definitely thick like can’t wrap your hand around it ‘girthy’,” You shoot Kento a wink. “And you Atsuya…” You drag it out just to watch him squirm. “are stupid thick at the base and stupid long everywhere else.”
Kusakabe beams like you just handed him a trophy. “See? Told you. Big-dick problems.”
Higuruma rolls his eyes but there’s a faint smirk. “And yet you still complain more than anyone.”
“Because it’s a curse!” Kusakabe throws his hands up. “Last girl I tried to hook up with—cute little bartender from that spot in Shibuya? We get to her place, clothes off, she’s all ‘yes, yes, fuck me’—then I line up and…” He makes a dramatic wince. “Nope. Too tight. Wouldn’t even take the head.”
You raise both brows. “You’re bragging about not fitting?”
“I’m bragging about the reason,” he corrects, smug as hell. “She was soaked, ready, begging—and still my dick was like ‘nah, we’re good right here.’ Had to finger her open for ten minutes straight before she could even think about taking it. And even then she was whimpering the whole time. ‘It’s too big, Atsuya, it’s too big—’” He drops his voice into a breathy imitation, then grins. “Music to my fuckin’ ears. She was into it. Left scratches down my back. Texted me the next day asking when round two was. I just… need a girl who can handle the whole package, y’know?”
You’re laughing again, half horrified, half turned on because the honey’s making you feel horny as fuck. “So what, you’re saying you need a custom pussy?”
“Basically.” He shrugs shamelessly. “But yeah. Big-dick tax.”
Higuruma snorts softly, leaning back. His slacks are tenting noticeably now—the honey working fast—and he doesn’t bother hiding it. “You talk like you invented the concept,” Higuruma says dryly. “Every guy with more than average girth thinks he’s suffering uniquely. Newsflash: most women don’t need a warm-up marathon unless the guy sucks at foreplay.”
Kusakabe clutches his chest in mock offense. “Excuse you, I’m a gentleman. I do the full ritual—kissing, fingering, clit worship, the works. Still gotta ease in though. You wouldn’t get it.”
Nanami, who’s been quietly nursing his beer finally speaks up, “You’re both overselling it. Size is irrelevant if technique is garbage.” He meets your eyes again, “And technique can make even ‘adequate’ feel overwhelming.”
“Oh-ho,” Kusakabe says, catching the shift in Nanami’s tone. “Kento’s getting defensive. What’s the matter? Worried your ‘perfect girth’ isn’t enough to win first place?”
Nanami laughs, arching one brow, “I don’t need to win anything. I know what I’m working with.”
“Exactly my point!” Kusakabe throws his head back laughing. “We’re all walking around pretending we don’t compare but let’s stop bullshitting.” He sits up straighter, suddenly serious—or as serious as Kusakabe ever gets. “I know I’ve got the biggest dick in this room. Hands down. Length, girth, the full combo. But words are cheap.”
He looks around at the three of you, eyes gleaming with challenge. “So prove me wrong. Or let me prove it. Right here. Right now.”
You blink. “You want to… what? Whip them out and measure?”
Kusakabe shrugs like it’s the most logical next step. “Why not? We’re all adults. Let’s settle this like men.” He grins wider. “Or like horny idiots who took sketchy gas station supplements—Fuck me,” he mutters, palm already drifting down to adjust himself through his sweatpants. “This shit’s no joke.”
You snort-laugh, heat crawling up your neck. “You’re actually doing this now?”
Higuruma tilts his head toward you, eyes half-lidded. “He’s been waiting for an excuse since middle school. Might as well settle it.”
Nanami pinches the bridge of his nose. “This is the most undignified conversation we’ve ever had. And we’ve had some bad ones.”
Kusakabe grins ferally. “C’mon. Pants off. We compare, then we… test compatibility.” He waggles his eyebrows at you. “You get final vote.”
“Okay… hold up.” Your voice comes out higher than you meant it to. You sit up straighter, legs still slung over Kusakabe’s lap, suddenly hyper-aware of how close his hand is to the seam of your shorts. “You’re seriously proposing this, a dick measuring contest?”
Kusakabe’s grin gets wider, “Yup.” Higuruma lets out an amused huff, “To be fair, you did rank us already.”
“Yeah, but that was theoretical!” You gesture wildly at the three of them. “This is… this is practical application. Like, actual dicks. Out. In the open. For science.”
Nanami’s voice is taunting, “And apparently for your entertainment.”
You shoot him a look and he just raises one perfect eyebrow like you started this. “I mean…” You drag a hand down your face, trying to sound reasonable even though you were fucking so soaked. “This is insane. This is so insane. We’re grown adults. We have jobs. We pay rent. Kusakabe probably has a dentist appointment next week.”
“Thursday,” Kusakabe supplies helpfully. “See? Normal people shit!” You point at him accusingly. Then you drop your hand and exhale hard. “But also… fuck.”
All three of them go still, waiting.
You chew your bottom lip for one more second, then let out a shaky laugh that’s mostly nerves and lust. “Damn it. I’m so fucking wet right now I can feel it on my thighs. And you three just spent the last fifteen minutes talking about how big your dicks are. So yeah. Fine. Whip ’em out. Let’s do the stupid comparison. Because apparently my dignity left ten minutes ago.”
Kusakabe lets out a triumphant “YES!” and immediately shoves his sweatpants down to his knees without another word. His cock slaps up against his stomach already glistening at the tip. The rest follow suit.
“Okay, c'mere boys," you say, sliding off the couch to your knees in front of them. The rug is soft under your shins. You’re eye-level with three very hard, very different cocks, and the visual alone makes your clit throb. “Let’s see.”
Kusakabe steps up first—cocky as ever. He’s thickest: heavy, girthy, maybe 8.2 to 8.5 inches but the width makes your mouth water instantly. Veins prominent, head flushed dark. He strokes himself once, smirking. You wrap your hand around him—fingers don’t quite meet. Not bad I guess, you think to yourself.
Next, Nanami. You have to use both hands again. One around the base—fuck, it’s wide—and the other higher up the shaft. Definitely 8.5 to 8.8 inches. It’s long enough that there’s still room to stroke. The head is flushed angry red, already slick. You give an experimental squeeze and he groans, hips jerking forward.
Higuruma last. Longest by a noticeable margin—8.7–9 inches, slimmer than the other two but with that elegant upward curve and a slight left lean. His cock would definitely bulge through. Darker shaft, flushed head glistening. He tilts your chin up with two fingers while you stroke him experimentally. “You pick a winner yet?”
You wrap a hand around each of them—Kusakabe in your left, Nanami in your right, Higuruma guiding your mouth first. “Too close,” you mumble against the head of Higuruma’s cock before licking a stripe up. “Need… more data.”
Kusakabe laughs already stroking the base of himself while he watches your tongue flick over Higuruma again. “Fuck, beautiful. You’re gonna kill us before we even start.”
You shoot him a mischievous look, then turn your head and take Nanami into your mouth instead, letting your lips stretch wide around that fat head. He hisses through his teeth, one hand immediately sinking into your hair. “Damn.” Nanami mutters, You hum around him in agreement, the vibration making his thighs flex. Then you pop off strings of spit connecting your lips to his tip.
“See? Data.” You wipe your mouth with the back of your hand, grinning up at them. “Nanami wins on stretch. My jaw’s already sore and I’ve barely started.”
Higuruma’s long fingers slide into your hair next, guiding you back toward him “Then let’s see how deep you can take length.”
You open for him willingly, tongue flat, relaxing your throat as he feeds inch after inch past your lips. Your eyes water almost immediately. When your nose brushes the neat dark hair at his base you moan, loud and shameless, the sound muffled around his cock. “Good girl,” he murmurs, thumb stroking the corner of your mouth where it’s stretched tight. “Look at you. Taking it so well.” You pull off gasping, spit shining on your chin, eyes glassy. “Okay—fuck—Higuruma wins depth.”
Kusakabe’s had enough of being patient. He steps in closer, fat cock nudging your cheek. “My turn. C’mon, baby.” You laugh because god he’s so impatient and wrap both hands around him again. Even with two hands there’s still shaft left to stroke. You lean in, licking a broad stripe from balls to tip, tasting salt and precome. Then you try. You really fucking try. The head pops past your lips with a stretch that makes your eyes flutter shut. You get maybe halfway before your jaw protests and your throat says nope. You gag softly, pull back, try again—deeper this time—tears pricking at the corners of your eyes.
Kusakabe groans like he’s dying. “Fuck—fuck—look at that. Trying so hard for me.”
You manage another inch, cheeks hollowed, before you have to pull off completely, coughing, laughing, wiping your eyes. Kusakabe pulls out of your mouth, flips you onto all fours. Nanami slides underneath so you’re straddling him, sinking down onto his thick length with a gasp. Kusakabe notches at your ass—slowly careful with spit and leftover slick—then pushes in.
You’re already so full from Nanami’s thick cock buried to the hilt in your pussy; every tiny shift of your hips grinds you down harder on him, the fat head nudging against your cunt. “Fuck—breathe, baby,” Kusakabe rasps, one big hand splayed across the small of your back, thumb rubbing soothing circles even as his hips keep that slow, inexorable slide. “You’re doing so good. Taking both of us so perfect.” You can’t answer. Your mouth is open on a silent scream, forehead dropping to Nanami’s shoulder. His hands come up to cradle your face, thumbs brushing away the tears leaking from the corners of your eyes.
“Look at me,” he murmurs, You lift your head just enough to meet his gaze and he kisses you while Kusakabe sinks another inch deeper. Kusakabe finally bottoms out his hips flush against your ass, balls heavy against your skin. You feel impossibly stuffed, both cocks rubbing against each other inside you. You break the kiss with a sob. “Oh my god—oh my god—I can feel you both—fuck—”
Higuruma has been patient, kneeling beside the bed, stroking himself long and slow while he watches. He climbs up behind Kusakabe so he can reach you. Long fingers thread into your hair, tilting your head back gently. “Open,” he says. You do immediately, your eager mouth falling wide as he guides that elegant length past your lips. You're a whimpering mess as the three of them find a rhythm almost too quickly, like they’ve done this before in some fever-dream fantasy.
Nanami rolls his hips up in shallow, grinding thrusts—never pulling out far, just enough to drag that thick ridge along your front wall over and over. Kusakabe matches him from behind, pulling out halfway and sliding back in. You whine around Higuruma’s cock and he pulls out just enough to let you speak. “Please—” The word comes out slurred, spit-slick. “Please—more—need—” Higuruma strokes your cheek with his thumb, “More what, sweetheart?”
You can’t think. Can’t form full sentences. “Need… to come—please—fuck me harder—need all of you—”
Kusakabe laughs, “Hear that? Princess wants it harder.” Nanami’s eyes flick up to meet the others—some silent agreement passing between them and then they move.
Nanami plants his feet on the floor and thrusts up harder, deeper, that thick cock bullying against your g-spot before pulling out as does Kusakabe. Leaving you clenching around nothing. Your hips twitch up instinctively, chasing the contact, and a confused little “wha—?” slips out. You blink, dazed and still throbbing. “Wait… what are you guys doing?”
Kusakabe huffs a low laugh, already shifting down the couch again. “Change of plans, princess.”
“Huh?” Your voice cracks, high and needy. You prop yourself up on your elbows, thighs still trembling, “You were literally about to—”
“We were,” Nanami cuts in, leans over you, caging you with one arm braced beside your head. “But then we realized something.”Higuruma finishes for him, “You haven’t come hard enough yet.”
Your brain short-circuits for a second. “I literally just—”
“Nah not like that,” Kusakabe interrupts, already settling back between your legs, his big hands hook under your knees and spread you wider. You open your mouth to protest—something about how you’re already sensitive, but Higuruma silences you with a kiss. “Let us spoil you a little longer,” he murmurs. “You deserve it.”
Before you can form another coherent thought, Kusakabe seals his mouth over your clit and sucks hard. Your back bows off the couch, hands flying to his hair as you moan into Hiromi’s mouth. Nanami moves to your left nipple, taking it between his lips and rolling it gently with his tongue while his hand cups the other breast, thumb flicking the peak.
Every pull of his mouth makes your hips grind up against Kusakabe’s face. Atsuya’s tongue starts flicking fast over your swollen clit, while Hiromi breaks the kiss only to trail his mouth down your throat, sucking another dark bruise into the soft skin just above your collarbone while his long fingers slide down to join Kusakabe between your thighs before Hiromi physically pushes him aside. Atsuya lets out an indignant “Oi—!” but he’s already being shoved to the side, sliding off the couch edge with an amused grin. Higuruma takes his place settling between your thighs. He hooks your legs over his shoulders and buries his face into you. He laps his tongue through your folds as Kento continues to switch between sucking your tits and giving you love bites while Kusakabe grips your hair forcing you to look up at him.
You’re about to come until the fucker pulls off, his eyes flicking up to meet Nanami’s over your body. “Your turn, Kento.” Nanami releases your nipple with a soft pop, pressing one last kiss to the peak before shifting down. Higuruma moves aside without protest, sliding up to claim your mouth instead as Atsuya moves onto your breasts now. Kento takes a second to admire how you’re glistening, swollen, dripping down your ass and onto the couch. What a fuckin’ sight. He flattens his tongue against your overstimulated cunt and flicks tiny precise strokes on your clit. “Fuck—Kento—wait—I’m gonna—” Your voice cracks, but he doesn’t stop. You come so hard your eyes tear up. You squirt hard, soaking Nanami’s chin, his chest, and the couch beneath you. Atsuya looks at you in awe, “That was the hottest thing I’ve ever seen. You gushed like a goddamn fountain.”
Hiromi helps you sit up while Kusakabe pulls you half into his lap, back against his chest, thick arms caging you. Nanami kneels close, one hand on your thigh as he continues to eat you out. Kusakabe groans like he’s in pain, stroking himself faster. “Fuck, Kento, don’t hog her. I wanna feel that pussy too.”
They stroke themselves in sync on you as you attempt to stop trembling from your orgasm. Kusakabe comes first spills across your stomach, thick ropes painting your skin in hot streaks. Higuruma follows seconds later landing on your chest, your throat, one even catching the corner of your mouth as he groans. Nanami lasts longest before coming hard across your thighs marking you everywhere. You’re covered dripping with them.
You’re slumped in Kusakabe’s lap, back plastered to his chest, legs still splayed wide across the couch cushions. Atsuya’s arms tighten around your waist, “Okay soooo…” He drags the word out, “Who the fuck won?”
You feel Nanami snort softly against your thigh where he’s still kneeling, lips brushing the sticky mess he just left there. Higuruma, stretched out beside you now, one long arm draped possessively over your hip, lifts his head just enough to arch a brow at Kusakabe. “Seriously?” he drawls, “We all just came on her, and your first thought is the dick-measuring contest from forty minutes ago?”
Kusakabe shrugs, chin hooked over your shoulder so he can look down at the obscene painting they’ve made of your body. His hands slide up to cup your breasts, his thumbs brushing idly over your nipples. “I mean… yeah? That was literally the whole point, right?” He grins, “We were supposed to settle who’s got the biggest, best dick in the room. And then we got distracted by—” he gestures vaguely at you, “So c’mon, Final vote. Who wins?”
You let out a breathless, disbelieving laugh that turns into a half-moan when Kusakabe pinches your nipples at the same time. “You’re actually asking me to rank your dicks again right now?” Your voice is hoarse, still shot from screaming, “Fine. Still tied. But Atsuya wins girth, Hiromi length, Kento… perfection.”
Nanami huffs softly against your hair. “Acceptable ruling.”
Higuruma hums, fingers still tracing lazy patterns through the come on your skin. “Or…” he says softly, “we can agree the only real winner is her.”
Kusakabe groans dramatically. “Fine. Tie. Whatever. But I’m calling dibs on eating her out first next time. I wanna see if I can make her squirt faster than you did, Kento.”
Nanami smirks at him already knowing there’s no one who knows how to eat pussy like him. “Challenge accepted, Atsuya.”
Hiromi laughs as he begins cleaning you up, “Give her ten minutes to breathe first,” he says, pressing a kiss to your temple. “Then we’ll see who really wins round two.”
Oh well, Men and their dumb big dicks.
