Masquerade ーA costume partyー (Pixiv Fanbox)

"Man, it's too hot~~."

　Unconsciously spreading my hand wide, I fanned my face with it. Unlike ages ago, the dreadful custom of office workers commuting in suits during summer had disappeared, but the heat this time of year was still unbearable. Honestly, I'd love to rip off this short-sleeved shirt and go completely naked. Well, doing that would probably get me arrested by my colleagues……

　My name is Isamu Ono, 29 years old. I'm assigned to the Violent Crimes Unit of the S City Police Department's Criminal Investigation Division. I'm 189 cm tall and weigh 112 kg. I hate to brag, but playing rugby through college gave me a pretty solid build. Walking down the street, I sometimes get double takes── not from women, but from men……

　I'm not a virgin, and I'm married, but aside from my wife, I've only had sex a few times with women who liked my beefy body, and I've never had what is called a proper relationship.

　Well, that's beside the point.

　Today, I was summoned by Chief Rikiya Komada. Despite being a non-career officer, he rose to the rank of Superintendent at the unusually young age of 45, making him an object of admiration for us subordinates. His hair is always slicked back with styling gel, and his ruggedly handsome face is captivating even to other men. Plus, his sky-blue police uniform looks like it might burst at the seams over his well-defined, muscular build.

"Thank you for coming, Sergeant Ono. This might come as a shock, but are you interested in special undercover investigation?"

　He's still so cool…… I was caught staring when Chief Komada's smooth baritone voice cut in.

"Umm…… undercover investigation? If it's an undercover investigation, surely there are better candidates than me? Like the Prefectural Police's Organized Crime Division 5……"

"Well…… that's the problem. This mission specifically requires a man with a 【Superb Physique】 like yours."

　On the overly sturdy-looking desk in the luxurious chief's office, photos and documents in envelopes were scattered about, as if to draw attention. Various photos tucked into files. They showed men wearing bizarre masks, dressed in revealing outfits. If it had just been guys wearing only underwear, that would have been one thing, but seeing some completely naked with their cocks erect made me so shocked I instinctively recoiled.

"Wait, wait a minute, Chief!! Guys like me…… aren't all these just gay……?!"

"……Correct. Every participant pictured here is gay. But this isn't just an orgy party for homosexuals. There's a rumor…… that 【the participants' Body Swap places】……"

　I wanted to dismiss it as utter nonsense. Body swap? That's something out of a comic book or movie. But the chief kept talking, his expression unchanged.

"Well, I don't buy that fishy story either. But it seems several participants in this party called 【Masquerade】 have gone missing. The police can't ignore that. That's why we've singled you out. Height, build, facial features── you fit the conditions the organizers would welcome perfectly. It might feel creepy since it's an investigation into something unknown, but please…… would you do me this favor?"

　With his large palms pressed flat on the table and his head bowed, I had no choice but to steel myself and say, "Yes sir…… I'll do it."

＊＊＊

　Three days later, I was in the basement of the designated building. Following men who seemed to be staff, I underwent a body search and was stripped completely naked.

"Seriously……"

　What they handed me was a mask covering the upper half of my face, tiny bikini briefs that didn't cover anything important, black business socks, and leather shoes. There's definitely someone with weird kinks among the organizers……

　I couldn't complain, so I reluctantly changed, put on the mask, and was ordered to lie down on a bed in a dimly lit private room. The room was filled with a sweet-smelling gas, and my consciousness began to fade.

　When I woke up, I wasn't 【me】 anymore. The enormous mirror in front of me reflected a man slightly shorter than me, muscular, with a goatee. His skin tone, his bone structure, everything about him was different from mine.

"……No way, could it really be…… my body really swapped with someone else's……?"

　My voice felt strange, and my body wouldn't move properly. Stumbling out of the room in confusion, I found myself surrounded by men wearing masks similar to mine, clad only in underwear, drinking and chatting.

　The air was thick with an overwhelmingly sweet, alcohol-laden scent and a haze of cigarette smoke so dense it obscured my vision. Maybe even the smell of marijuana was mixed in. An eerie atmosphere and a lewd, sultry heat hung heavy in the room.

　After a while, one of the men spoke to me.

"You…… first-timer, huh? You look pretty awkward."

　His deep voice matched his bodybuilder-like build, his skin deeply tanned. His arms were thick as logs, his abs sharply defined in six-pack lines, his pectorals full and rounded with nipples standing erect. His powerful crotch strained against the small patch of fabric, looking almost too tight.

"Yeah…… that's right. It's my first time experiencing something like this, so I'm not used to it yet."

"Hahaha, I was the same at first. Don't worry about it, you'll get used to it soon. Your body, you know, surprisingly quickly becomes 【your own】. Enjoy yourself, have a drink. Here."

　He forcefully pulled me by the shoulder and led me to the sofa by the wall. Sitting down beside me, he poured liquor into a glass and made me drink it. I was usually good with alcohol, but downing it in one gulp made me feel drunk almost immediately, my head spinning. Apparently, this body I was currently using couldn't handle alcohol well.

　As we shared drinks, I felt something shift inside me. Despite the insane situation of being inside a stranger's body, my fear strangely faded, and my mind began craving pleasure. Then, seeing the muscular physique of the man before me, I reflexively swallowed hard. His casual gestures, the sharp, sweaty scent of a male, the movement of his powerful muscles…… for some reason, it all became strangely captivating.

"I like you. How about you? If you're up for it, wanna hang out together?"

　The guy pulled me closer by the waist and whispered in my ear. His hot breath tickled my neck, sending shivers down my spine. Ever since I got this body, my heart pounds wildly at every little thing. Could it be that using this gay brain has even changed my sexual orientation?

"H-hold on…… I'm not mentally prepared yet."

"Mental preparation? Mental preparation, huh…… You don't need that. Because, you know, 【your body】's been ready and waiting♥"

　His hand touched my cheek through my mask. It was hot and rough. Then, his thick lips pressed against mine. His tongue forced its way in, ravaging my mouth.

"U……n……♥"

　Alongside the revulsion, an indescribable pleasure shot through my spine. It felt like I wasn't myself anymore. As I responded to the man's rough kisses, heat spread between my legs, and in an instant, my cock sprang free from the small piece of cloth. It was nothing like kissing a woman. I could feel the sperm raging inside my balls. This body seemed to want the man in front of me.

　The part of me that was supposed to be protected was definitely starting to creak. I'd never once been interested in a man in my entire life. Yet now, I couldn't suppress the urge to touch this stranger's skin. The scent of sweat emanating from his body tickled my nostrils, and the thoughts in my alcohol-fogged mind grew hazy.

──This is part of the mission. It's necessary for a smooth investigation.

　I murmured this to myself as if convincing myself, burying my face in his muscular chest. Rubbing my nose against his thick, tree-trunk-like neck, I returned his kisses like a spoiled child, and the man chuckled happily in a low voice.

"Hehe…… You're really into this, aren't you? Alright, let's make it feel even better♥"

　My mind is flooded with euphoria from being accepted by a man. Pre-cum drips relentlessly from my cock, and against my will, my asshole throbs and aches uncontrollably. Even though I'd never played with my ass in my life, the sensation of being fucked by a man came flooding back like a memory I'd forgotten. It felt like unfamiliar memories were bubbling up from the depths of my brain. The pleasure of having my anus scraped raw by an incredibly thick cock was thickly coated onto this body.

"Hey…… Hurry…… I want your cock now……♥♥"

　I couldn't hold back, thrusting my ass out and rubbing the bikini-clad crack against his crotch. Responding to my plea, he grinned and peered into the depths behind my mask.

"Don't rush…… Let's enjoy this slowly in the back room♥"

──This is also for the investigation.

　I nodded at the man's words while wrapping both arms around his neck. Dopamine flooded my brain, my heart pounded so hard it felt like it might burst, and my whole body grew hot. My cock was rock hard, transparent fluid dripping from the tip of the glans.

My asshole twitched and throbbed, preparing to receive the massive cock of the man before me.

　No guilt surfaced. Surely the person whose body I'd swapped with was now mating with a beefy stud like this guy in my body. That thought consumed me with perverse excitement, sending shivers of pleasure through me that made my lips part in a smile.

＊

　A small private room tucked away at the back of the venue. Stepping inside, dim lighting and damp air greeted us. Lotion bottles and folded towels were neatly arranged on the table.

"Here, sit down."

　Prompted, I sat down on the bed, and the man sat beside me. My current height was probably around 170 centimeters. Compared to me, he had a build equal to or larger than my original self. Finding myself looking up at someone else for the first time in ages felt strangely fresh. At the same time, my breathing grew heavy. Perhaps the body I was currently using had a tendency to become extremely aroused by men with physiques larger than my own.

"Hey, bro……"

　The man whispered in my ear. His voice was low, like poison seeping into my ear and melting my brain. I gasped involuntarily.

"Bro…… your crotch is soaking wet."

"……!"

　Looking down at my crotch, my bikini briefs were indeed darkened. For my underwear to be this soaked with pre-cum was unthinkable for the old me.

"Don't be embarrassed. Everyone gets like you here. You're gay too, so you like this kind of thing, right?"

　I don't like guys. Those words nearly slipped out of my mouth. Back in my sports club days, I'd kissed someone as a joke once. But it just felt disgusting. There was no way a guy could like another guy…… or so I thought──.

　But no matter how I thought about it, this body was reacting. I couldn't deny his words. Was it because of this body's memories and habits? Or was my own mind itself changing? Without finding an answer, I just stared blankly at the man.

"I'll be gentle……"

　He pushed me down, his body pinning mine. I could have resisted. But my body was frozen stiff, like stone, unable to move. Only my heart pounded like a drum. A soft sensation followed as a tongue slipped into my mouth. The raw sound and warmth of saliva hit me directly, making my brain feel like it was boiling.

　Unconsciously, my current body spread its asshole wide open, waiting to be violated by the massive man pinning me down. My bikini briefs had completely abandoned their purpose; nothing protected my most precious spot. Though my body was rigid, I could only brace myself for what was next.

"It's okay…… relax."

　As if sensing my tension, the man whispered softly. His words carried a certain reassurance, yet at the same time, I felt a pang of pity.

(I'm a detective, but what the hell am I doing……)

　Even as I questioned myself, the situation progressed. The man's thick fingers moved to spread my buttocks apart, and in the next instant, something with an overwhelming sense of mass was pressed against the hole.

"OHHH……!!"

　The pain of tearing my anus far outweighed any sense of foreign intrusion. Still, this body seemed accustomed to sex between men and was trying to adjust somehow.

"Does it hurt? Just bear with it a little…… It'll feel good soon…… Okay?"

　Contrary to the terror and agony my body felt, the man relentlessly pushed his hard cock deeper, twisting it inside me.

──Thud, thud-thud-thud!!!

"NOOOO!! So, so deep inside……!"

　The sensation of her entire intestinal wall stretching to accommodate the thick cock. It felt like it was thrusting right up to my organs.

"Haaah~, all the way in……♥♥ Moving now……"

　The piston motion began. Slowly at first. But as the pace gradually quickened, the intensity grew. With each thrust of that thick cock in and out, an overwhelming pleasure surged through me, so intense it felt like sparks were flying in my brain.

"Ahhh~!! Damn! Harder, harder~~~♥♥♥"

　Before I could even register the shock of my own loud cry, I was already lost in the chaos. It felt so good I couldn't think straight. Getting fucked in the ass felt this amazing!!

"Hey! How’s that?!!"

"Ohhh♥ Yesss…… Anal sex is the best!!! My asshole’s turning into a pussy♥♥"

　My anus now functioned exactly like a female pussy. When my intestinal walls were rubbed, the flesh would tighten around his cock with a satisfying squeeze. The grip of my anal sphincter was perfect too. It would not be an exaggeration to say it is specifically designed to serve men.

"Hmmm…… What a tight grip…… You’ve got a pretty damn good asshole, don’t you…… I’m gonna fill you up with my seed……♥"

　Gripping my hips like a vise, the man thrust violently, over and over. Each stroke made the mucus overflowing from my anus foam, creating a lewd, squelching sound at our point of connection.

(What the hell is this…… Why am I feeling so damn good with a man's cock inside me……)

　Even though I have a wife and a daughter, right now I'm madly craving and reveling in some guy's cock. I couldn't possibly accept this side of myself, yet part of me tried to convince myself it was okay with the excuse-like thought, 'This is just work, so it can't be helped.' The only way I could rationalize it was to tell myself that since this body wasn't my own, I could do whatever I wanted with it.

　Without knowing what my true feelings were, time just passed…… and eventually, reaching my limit, I was about to climax inside this body.

"I'm cumming! I'm gonna cum!!"

"Me too!!"

　The man's thrusting accelerated further. As he reached the deepest part of my bowels, his ejaculation began. A torrent of burning heat filled me, and trembling all over, I too came.

""OHHHHHH~~~♥♥♥""

　My semen spurted out with such force that it drenched not only my face and chest but also soaked the sheets through. The man's thick cum filled my bowels completely, and the excess liquid, finding no place to go, flowed back up and overflowed from my anus.

　Even though I was a man, even though I was heterosexual, I couldn't help but feel confused. Alongside the anger and shame at being violated and creampied right now, there was also a strange sense of fulfillment and euphoria mixed in. It was almost as if I was deluding myself into thinking that the pleasure of being dominated by a male with a superior physique was what I had been seeking all along. It felt like I wasn't just becoming accustomed to this man's body, but that my very mind was being forcibly reshaped.

"Hey, bro, you okay? Nice asshole you got there…… Let's do it again sometime. Next time, I might be the one getting fucked, though♥"

＊

　When I was first ordered to attend this shady party full of sleazy men, 【Masquerade】, I felt nothing but disgust.

　A place I couldn't make sense of, filled with people with incomprehensible kinks like 【Body Swap】. Sharing drinks with homos I first met nearly naked, and even having sex with them—as a detective and as a human being, it was a world I couldn't fathom.

　But now? Now I found myself actually looking forward to that 【unreality】.

　The first time, I inhabited the body of a man in his forties—hairy, muscular, but not very tall. Using someone else's body felt utterly unnerving at first. Yet, as I tasted pleasure for the first time, my consciousness began to waver.

　The second time was a young, muscular guy who looked like a gym trainer. A lean, low-body-fat physique. The sensation of thrusting my cock into a man's asshole for the first time was incredible.

　The third time was a guy with deep-set features and a slightly dark complexion, looking kind of mixed. Both his body and his desire were fierce, animalistic. That night, I got hard over and over, fucking and getting fucked all night long.

"Ah……yeah, I see…… So you really swapped bodies with someone else? That's incredible……"

　After completing my third undercover investigation, I reported on the 【Masquerade】. Chief Komada, his hands clasped beneath his chin, wore an unpleasant expression. His eyes held a look of utter disbelief. It was clear he didn't believe a word I was saying. But perhaps lacking any evidence to prove it a lie, he seemed willing to hear me out for now.

"Yes, Chief, exactly as you said. Every time 【Masquerade】 happened, I swapped bodies with someone else and became a completely different-looking person!"

"I-I see…… Anyway, continue investigating 【Masquerade】. It might be connected to some large-scale crime."

"Understood!"

　Despite my dramatic rant, Chief Komada seemed to conclude I must have been hallucinating. It was only natural. By any reasonable standard, believing in something as absurd as body swapping was difficult. Still, I was grateful to be able to continue the undercover operation. My very reason for living could now only be fulfilled within the 【Masquerade】.

……And tonight.

　I was inside another man's body again.

　The large mirror reflected the figure of 【a man who was not me】, still hiding the upper half of his face with a black mask, clad only in tight bikini briefs. Broad shoulders, bulging pectorals, slightly relaxed abs—I couldn't help but let my lips curve into a smile. I was already completely addicted to body swapping.

"Such a nice body tonight too……♥"

　A voice not 【my own】 trembled my eardrums, making me realize my body had swapped with someone else's. I'd grown accustomed to this phenomenon of 【Body Swap】 and no longer felt any discomfort.

　The venue lights dimmed slightly. Light music played, easing the strange atmosphere, as men holding glasses began whispering sweet nothings. Then, a man approached me—a warrior-like figure, a full size larger than me.

"Hey, wanna join me?"

　Drawn by his deep, sensual voice—a perfect match for his powerful physique—I walked toward him. His crotch was already bulging. Our eyes met. Following my instincts, I wrapped my arms around his thick neck. We embraced, seeking each other’s warmth, and kissed.

"Mmm……♥"

　The sound of saliva exchanging echoes in my ears. The clang of muscle against muscle, the sensation of hardened cocks rubbing together—it sends shivers down my spine. Burying my face in the man's thick chest while letting out hot breaths, I can almost hear his heartbeat. Much rougher and more rugged than a woman's soft body. His hot muscles feel unbearably precious.

(Ah…… This is it…… I was born to mate with other males. But……)

　During sex, fear suddenly gripped me. If this undercover operation ended and I could no longer participate in 【Masquerade】, could I ever return to my old life as a 【serious detective】?

"What's wrong, bro? Something bothering you? Just forget about it for now and enjoy yourself with me."

　As if reading my mind, the man spoke gently. His words numbed my brain like a drug.

　Until just the other day, I thought getting fucked in the ass was disgusting. But now, I can't stand it—I want to be fucked by a man's cock. This body craves it. No, maybe even my soul desires it now.

　Inside the private room, enveloped by his animalistic breathing, I just kept moaning in his arms.

＊

"……What the hell is this……"

　The fifth 【Body Swap】. The moment I woke up, I shuddered at my own body.

　My large nipples had silver piercings. And from my arms to my shoulders and across my chest, an elaborate tattoo spread. My skin was dark, muscular yet covered in thick fat. My fingertips even seemed to carry the lingering smell of tobacco tar. Looking down at my lower abdomen, there──

"……!"

　Several pearls were embedded in my penis. A wave of disgust washed over me. The yakuza──, this body undoubtedly belonged to someone from the underworld. I, who had lived as a detective with a sense of justice in my heart, had ended up inside the body of an antisocial force. My heartbeat quickened, thumping loudly, and sweat broke out in a cold shower.

　Terror and disgust. But at the same time……

(……Is this…… me?)

　I stared blankly at my reflection in the mirror before me. Thick brows, piercing eyes. My closely cropped hair was flecked with gray, and a faint scar resembling a sword wound lingered on my jaw.

　Getting used to this man's body would be dangerous! My detective instincts sounded the alarm, yet something else whispered.

──How good could it feel for me, a detective, to use this yakuza body, the complete opposite of who I am?

(...!!)

　I frantically tried to shake off the thought, but my lower half wouldn't lie. Had this body been abstinent for so long? My brain felt like it was about to explode from the confusion, yet my grotesque cock writhed like a separate creature, defying my will. My balls were swollen and plump, probably stuffed full of semen.

　Hurry up and let me out, the pearl-encrusted cock trembled and quivered. Stroking it with my thick fingers sent an intense wave of sensation through me like nothing I'd ever felt before.

(Ah…… this is……insane……♥)

　Transparent fluid was already seeping from the dark red glans. Anyway, once the party ended, I'd return to my original detective body. I'd enjoy sex in someone else's flesh, just like before.

　Torn between anxiety and curiosity, I headed toward the venue. The venue was enveloped in its usual, lascivious atmosphere. Within it, one man stood out. Tall and imposing, his face half-hidden behind a mask, yet his features carried a vaguely familiar air.

　That's…… my body!

"Hey! Hey, buddy. Isn't that body of yours actually mine?"

　The low voice that emerged from 【my】 lips. It felt strange, yet it oozed sensuality.

"Oh, it really is my body after all. How's my body? I hope you're enjoying it……"

　The man in front of me, who'd been groping all over my body, introduced himself as Shigeo Yamaguchi. I reflexively blurted out my real name too. I panicked for a second, but my name isn't that uncommon, so it should be fine.

"This is my first time meeting someone I've swapped bodies with in a 【Masquerade】. But…… it's interesting, isn't it? Seeing myself through someone else's eyes. Somehow…… it just looks so damn sexy♥"

　Saying that, Shigeo wrapped his hands around my waist. His rough palms. Even though they were 【my】 hands, it made me excited.

"Since we've got this chance, wanna have sex? Just thinking about two swapped people fucking gets me crazy turned on, doesn't it?"

　At that voice, my body flinched. I'd been held in someone else's body before, many times. But being held in my own body? That was a first.

"……Okay. Let's go."

　As I answered, a low, husky voice—not my own—echoed from my vocal cords.

＊

　We entered the private room, facing each other in the enveloping silence. Shigeo's—【my】—body slowly inched closer.

"……Damn, you've got a plump, lewd body, don't you, my body♥"

　Saying that, Shigeo ran his hands over my chest. I accepted it. The yakuza's body and the detective's body. Ironically, each was drawn to the other's physique. Lips touched, tongues entwined.

(This is kissing 【me】. 【My】 lips, 【my】 tongue……, the taste of 【my】 saliva♥♥)

　It felt like tasting forbidden fruit. A sense of transgression tightened my chest. Just kissing made my cock ache unbearably. Seeing this, Shigeo knelt before me and suddenly took my pearl-studded cock into his mouth.

"Haahhhhh……♥♥"

　The pleasure of being enveloped by slippery mucous membranes. I couldn't help but let out a pathetic moan.

"Slurp…… Broo, feels good?"

　Shigeo asks, still sucking. His saliva mixes with my pre-cum, filling the room with a lewd sound. The detective 【me】 was sucking on the yakuza's pearl cock. The sight filled me with a twisted excitement. Shigeo sucked up while kneading my balls. It felt so good my knees trembled.

"Shit……, I'm gonna cum……"

　As soon as I said that, Shigeo sucked even harder. He thrust it deep into my throat, making my vision flicker and blur. The pearl-like texture clung to my cock, refusing to let go. I couldn't hold it anymore, I couldn't take it──!

　But the instant I was about to ejaculate, Shigeo pulled away.

"Not yet. We're gonna cum together, okay?"

　He grinned maliciously, then pushed me down onto the bed. I was forced onto my back, legs spread wide. I was already used to this position. The thought of being violated now made my heart race with anticipation. Being violated by 【me】. Violated by my own body. That fact excited me more than ever before.

"This mask's getting in the way…… We know each other's identities anyway, so let's take it off and do it."

"Are you sure?"

"As long as we don't get caught, it's fine. Besides……"

　As Shigeo said that, he ripped off the mask. There was a familiar face beneath it. It was unmistakably 【my】 face. But something was different. It couldn't be my imagination that he didn't look like a detective.

"Don't you think it's hotter when we can see each other's faces clearly?"

　The smirk on 【my】 face had a certain sensuality to it, and I sensed something like malice. I too removed my mask, revealing my bare face. Even though I wasn't looking in a mirror, someone who looked exactly like me stood before me. It was a strange sensation. 【My】 own body loomed over me. 【My】 face fills my entire field of vision. Staring into my own eyes felt absurd. A familiar face, a familiar body, a familiar cock. Yet someone else was using it. Even though it was the body I'd lived with for 29 years, the fact someone else was using it made it feel like it wasn't mine.

　His stern, detective-like face, his sturdy physique honed daily through kendo training, and even that magnificent cock, rock-hard despite being with a man—all of it belongs to me. Yet somehow, it all looks like it belongs to someone else. That makes it feel even more erotic.

　I slowly closed my eyes. Our lips touched. Tongues met and entwined. 【My】 saliva flowed into my mouth. I shivered with pleasure as my mouth was ravaged. While kissing, my nipples were pinched and toyed with by his fingertips. Two cocks, dripping with pre-cum, slurped and squelched as they tangled together. It felt so good. Once I knew this kind of pleasure, there might be no going back.

"Hmm…… I never knew having sex with 【myself】 could feel this good……♥ Looks like you're ready too, huh? Even though you're a yakuza, I'm gonna shove my thick cock right into that loose asshole you've stretched out from fucking so many men♥♥"

"Ahh! Your cock's entering my asshole……! Damn, 【my】 cock's way too big♥♥"

　The detective's massive cock was being sucked into the yakuza's body. Shigeo's face wore an expression utterly unbecoming of a detective, drowned in pleasure. I was sure I must look just as melted myself.

"Ahee……! Seriously, this is gonna get addictive. 【My】 asshole feels way too good……! Aaah!"

　The sound of two macho bodies colliding echoed through the room like an explosion. 【My】 cock was being thrust in and out of my own asshole. I was watching my own cock go in and out. It felt like I wasn't even myself anymore.

"That's incredible……! I'm gonna cum right now……!"

　Shigeo's voice grew desperate. I was close to my limit too. Unable to withstand the pleasure surging up from my ass, my hips started moving involuntarily.

"Ohhh! Right there……!!"

　He attacks me like he knows my weak spot inside out. My prostate gets crushed and crushed by his cock, and my mind goes completely blank. My body arches like a bow, twitching and convulsing.

"My cock's twitching like crazy too…… This feels so good, it’s insane……! Heh heh heh…… After all, this macho body is gonna be mine♥♥♥"

"Wh……, What do you mean?!! Mmm……♥"

"Ohhh♥ This party called 【Masquerade】 is where VIP members like us select the bodies of unsuspecting, muscular regular members. Why do you think you never ran into the person you swapped with during the party? Well, it's because if swapped partners have sex and 【cum】, they stay swapped and can't switch back! So, normally, swapped partners are sent to different venues to avoid meeting each other…… that's how it works♥ Here we go! How's that, my big detective's cock?"

"Wh-what……?! Ugh……♥"

　Even as I'm told this unbelievable truth, my body trembles with pleasure. Now that I know something this good, there's no going back.

"Ahh♥ Perfect……♥ Just that pre-cum alone makes all your memories flood back into my head, uuuh♥♥ Your first ejaculation in second year middle school, jerking off to naked women on porn sites. Your first sex in third year high school, with that manager one year younger than you♥ I can't take it, everything about you is racing through my brain……♥ My beloved wife I met in college……, our precious daughter we conceived right after marriage……, our happy family with them both♥♥ Tonight, I'll use this thick cock I've been shoving up men's asses to fill your slutty wife's pussy with loads of cum♥♥"

"No, stop it……! Not my family……! Don't you dare touch my family!!"

"Huh? What the hell are you talking about? This body's mine now, got it? And hey, since this body's also yours, the cock shoving into your wife's pussy is 【Isamu Ono】's cock. No problem at all, right?! Besides, you're getting turned on, aren't you? Your body's been taken over by a yakuza, your wife's been cuckolded from me, and 【you】 might even get her pregnant with a baby♥"

"Nooo……"

　Despite this hopeless situation, I found myself inexplicably aroused. Shigeo's movements grew more intense. 【My】 balls slapped against my ass, making a slapping sound. Each time my prostate was stimulated through the intestinal wall, a shockwave shot straight through my skull.

"Gahahahaha!! I'm cumming! I'm gonna cum, baby♥♥♥ Straight cop Sergeant 【Isamu Ono】, cumming while searching a yakuza's asshole♥♥♥"

"Aaaah! You're cumming inside me……! My body's being taken over……♥ Hot stuff's pouring into my asshole……! Don't come inside meee, the yakuza's memories are cominggggg!"

　Synchronized with Shigeo's ejaculation, my cock spurted out a massive load of semen. Simultaneously, an overwhelming flood of information surged into my brain. An unpleasant sensation, like tentacles writhing inside my cerebral vessels. Yet at the same time, I was assaulted by pleasure so intense it felt like my brain was burning up. The memories of 【Isamu Ono】 and 【 Shigeo Yamaguchi】 began to blend together.

　The sensation of our brains melting into one. My sense of self crumbling away. The reason was blown away. In its place flowed Shigeo's thought patterns. The way of life as a yakuza, the experience of having slept with countless men, how to navigate the underworld… …Everything about 【Shigeo Yamaguchi】 poured in. The very essence of Shigeo's life was being engraved. Violent sexual desire, destructive impulses, the urge to conquer. Everything I was was being replaced by everything Shigeo was.

"Hehehe♥ This feeling is the absolute best, no matter how many times I experience it! With this, Sergeant 【Isamu Ono】’s body is completely mine now……! Did you enjoy it too? Hehe……, you’re making such an amazing face. I can tell your brain’s all mushy now, Mr. 【Shigeo】♥"

"……♥ ……♥"

　I could see Shigeo, who had pulled his twitching cock out of me—still spasming in small jerks, perhaps lost in the afterglow of his climax—looking down at me with a smug grin.

"Mmm……♥ Right then…… I'm gonna use this body to exploit the police organization to my heart's content♥ At first…… I need to learn more about this body's family…… 【My】 wife's name is~…… Ah, hello? Yuka? I'm heading home now. Work's finally settled down, so let's have sex tonight for the first time in ages♥ Bareback, of course. I'm gonna fill Yuka's womb nice and full with my cum♥ Wait for me, hoping for our second child. Love you, bye♥ ……Alright. That's good. Heh heh, this is gonna be fun. I wonder how it feels for a wife to get her beloved husband's body taken over by a yakuza and have your cock inserted inside her♥ I can just picture the look of joy on her face! Heh heh heh heh!"

　【My】 voice echoed faintly from afar. All I could do was stare blankly into the void. Who the hell am I? A cop? A yakuza? I don't know anymore. I can't think. I don't need to think. Because──, I'm not 【Isamu Ono】 anymore.

"Good work on the undercover investigation, Sergeant 【Isamu Ono】."

　Chief Komada, seated deep in the leather sofa, spoke with a smile. The air in his office felt stifling, unlike any daytime police station.

"So, how's your reborn body feeling, 【Isamu】?"

　At those words, I shrugged my shoulders slightly and lifted the corners of my mouth.

"It's fantastic, Chief. I can't thank you enough for assigning this mission to 【me】. Every time I look in the mirror, my cock throbs with desire♥"

　Chief Komada stroked his beard with satisfaction.

"With a man as loyal to the duty as you, our station is in good hands♥"

　The chief sat beside me and, with a hand hidden beneath the table, began stroking my hardened crotch. This body which I recently had taken over from 【Isamu Ono】, was still unfamiliar to me. Though my stiff cock had already thrust in and out of 【my】 wife Yuka's pussy countless times, being kneaded by a man's rough hands made it react sensitively.

　Ten to one, the Police Chief 【Rikiya Komada】 had also been swapped with someone, just like me and 【Isamu Ono】. And not by some honest, incorruptible cop, but by an evil, lecherous homo bastard. He must surely love sweaty, macho bodies and the smell of cock just as much as I do.

"Chief Komada……♥ Is it okay if I start digging your asshole with my thick cock soon?"

"Uhehe♥ Okay……, I've been waiting for this. For the moment to offer this body's anal virginity to a beefy detective like you……♥"

　Chief Komada stood up and pulled down his pants and underwear in one swift motion. With a sound that perfectly matched the onomatopoeia 'BOING!', the chief's cock sprang out.

"While I was thrusting my cock in and out of my wife's pussy, I used an extra-thick dildo to stretch this tight little asshole over and over again♥ I've been holding back all this time just jerking off, so I want a hard cock……♥ Hurry…… shove your thick, thick cock right into my innocent little asshole, force it in hard♥♥"

　The chief's lewd invitation pushed me past my limit. The lower half of this police officer, solidly built and well-trained. At the center of his taut, muscular buttocks, a hard, constricted anus beckoned me, ready and waiting. I gently touched the anus with my fingertips, generously coated in the lotion prepared on the table. I carefully loosened it, stretching each wrinkle one by one.

"Ohhh……♥ Thick manly fingers……♥ Feels…… so good……♥"

　Chief Komada drooled, his face contorted in ecstasy. It ruined his normally stern features. I pushed my middle and index fingers deeper and deeper inside him. I stirred them around, scraping against the intestinal walls. The sensation of hot flesh was palpable. The chief's breathing grew increasingly ragged.

"Haa……♥ Ahh……♥ Sergeant Ono, hurry……♥ Not fingers, give me your cock……♥"

　A low, intoxicating baritone voice, so deep it made my lower abdomen ache. That sweet, begging voice echoed through the room. I pulled my fingers out and thrust my rock-hard, thick cock all the way to the base into the tight hole in one go.

"Ohhhhh! It's hereeee♥ The thick, muscular detective's…… thick cockkkk♥♥"

　The chief's voice tinged with delight. Unexpectedly, a thick, skin-covered, blackened, massive cock—Komada's—spurted out a powerful jet of milky white fluid. Just from me inserting my cock into his asshole, he seemed to have already come. I didn't care and started thrusting my hips. The sound of flesh slapping echoed. The grip inside his bowels tightened.

"Oh my god♥ It feels so good♥ It feels too good! Fucking my wife is nothing compared to getting fucked in the ass by a man♥ More……! Fuck me harder♥♥ Ugh♥ Ahhh♥ Right there♥ Attack my prostate harder, crush it♥ Ooooh♥ I'm about to cum all over the place, my balls are swelling up♥ 【My】 body is screaming for thick, sticky cum, you hear me?"

　Chief Komada writhed in pleasure. He was thrusting his hips in rhythm with my movements, his subordinate. This police station had effectively fallen into the hands of the devil. The chief will undoubtedly continue sending physically superior officers to go undercover in 【Masquerade】. While it remains unclear who exactly is inside the current Chief 【Rikiya Komada】, at least my goals aligned with his. We'd swap the bodies of those strong, honest men for those of lecherous homo bastards who love cocks and assholes.

"Mmmph! I'm cumming~~~!! I'm shooting my sticky cum deep inside your tight little asshole, Chief, OHHHH♥♥♥"

"Yeahhh, give me all of it! Fill my belly with your seed, please♥ Ooooh♥ The thick, muscular detective's sperm is filling my insides♥ I have a wife and kids, but I'm gonna get pregnant♥♥ Hehe! Getting my ass pounded by your thick, huge cock……♥ I'm becoming addicted to male-male sex……♥♥"

　I violently attacked Chief Komada's prostate, filling his rectum with copious amounts of cum. Simultaneously, Chief Komada also ejaculated forcefully. The chief's office choked on the sexual stench of two men. We who had taken over someone's bodies. By intertwining their flesh like this, we satisfied each other's desires. Imagining that we two police officers would continue living our lives pretending to be straight, my erection refused to subside.

"Haa……♥ Mmm……♥ Your cock's still erecting at attention like it wants more, isn't it? You're slacking off, Sergeant Ono! If you want to keep working as a detective, you'll need to get that tight little asshole stretched out to fit more cock……♥ I'll train it properly with my big cock♥"

　Chief Komada grabbed my big ass and rammed his thick cock deep into my asshole. I let out a cry of ecstasy. The tables had turned in an instant. Just as I'd relentlessly fucked the chief's asshole, I imagined him now relentlessly fucking mine, and couldn't help but make a blissful face.

"Nooo♥ Chief……♥ Your cock inside my asshole……♥ I'm cumming!"

"Hey, hey, where'd all that bravado go? If you're a detective, act like one! Show me some manly spirit! Hmph♥ Hey♥ Get fired up! Ooooh♥ It's tight, so tight♥ I can't take it! Become my personal meat toy for my huge cock! Hmmmm!!"

　We fucked like beasts in the chief's office. It was a lewd scene that would have been utterly impossible back when 【Isamu Ono 】 was still on duty. Just moments ago, these men were running around catching criminals for the citizens. Now, we were indulging in perverted play, fucking each other's asses. However, for us now, this was pure bliss. Taking over another's body and engaging in sex, driven solely by our own desires—that was what mattered──.

"Guhhh……♥ Chief……♥ I'm cumming……! Please fill my asshole with your thick, gooey cum, pleaseeee♥"

"Hehe♥ Of course I will♥ I'll use my thick, huge cock to tear open the deepest depths of your bowels♥♥ Sperm rising up through your urethra, oohhh♥ I'm cumming♥♥♥ CUMMING!! I'll pour my thick, concentrated cum deep inside your ass until every last drop is drained from the police chief's balls♥ Isamuuuuuu♥♥"
