Mysterious Mist Sauna (Pixiv Fanbox)

　When he opened the frosted glass, a peculiar smell tickled his nose. It was the smell of a public bath. As if guided by the faint scent, Satoshi Tokura took step after step into the bathhouse.

　The steam made visibility poor and the humidity was high. Several people were soaking in the bathtub, which was covered with a milky white haze. Some were taking a break after finishing today's work, others were relaxing and recharging themselves for tomorrow. Their faces were all relaxed and smiling.

　Although he was excited to visit a public bathhouse for the first time in a long time, he looked around and was disappointed. There were many elderly customers. Here and there, an elderly man stroked his thinning gray hair head back, a stiffly wrung towel on top of it, and squinted pleasantly.

“Hah……, It's a bad day…….”

　Satoshi let out a loud sigh and headed for the sauna. There were groups of college students and fathers with their children, but they were all underweight or, on the contrary, too middle-aged and overweight, so he wasn't interested in them. He had no choice but to pull open the rather heavy door and step into the sauna he wanted.

　The heat was so oppressive that his face naturally turned into a frown. Inhaling the air, the mucous membranes of his nose ached just a little, as if they were twitching. The sauna was one of the reasons he had come to this public bathhouse. Not only could he endure the high temperatures, but the satisfaction of sweating in this mist sauna, surrounded by misty steam, was hard to find in other public bathhouses. What's more, it has a mysterious power──

(Whoa……)

　There was only one visitor in the room. With a dazed look on his face, he turned his attention to the TV, which was broadcasting the news. He was a middle-aged man with a beard and regent style. His eyebrows are thick and his nose is large. His stern face, with prominent cheekbones and thin lips, was wild and manly.

　But what caught Satoshi's attention even more was his body. His well-trained pectoral muscles were thick and bulging, his arms and legs were thick as logs, and his shoulders were stout and strong. The thick veins between the eyebrows and on the biceps, and the thick body hair all over the body, are all very glamorous. Although his crotch was not covered by a towel, he was more or less embarrassed and covered it with his large, craggy palm.

(I thought it's a bad day, but I guess today was my lucky day♥)

　He compares that man's voluptuous body with his own body spread out below. He chose a muscular body for 【the other day】, so he doesn't think it looks that bad. However, he was getting tired of his body, so next time he wants to become macho like the man. He would love to have such a fine chest plate and cracked abs…… He was just thinking that.

　After a while of being transfixed by his fantasy, the man's eyes turned from the TV to Satoshi's face.

“What's up, bro? Do you need something?”

“No, no.”

　Satoshi's chest heaved with excitement at the bluntly uttered words. The voice that came out of his mouth was also low and sexy, in a way that matched his physique.

“What the…… fuck are you? Don't look at me like that! You're disgusting!”

　He swore at him with an annoyed expression on his face, and Satoshi replied, 'Excuse me,' as he sat down in a diagonal position. 'I quickly removed my eyes, but would he still be looking at me?' Just thinking about such a trivial matter sent a thrill of elation through Satoshi's body. Underneath the towel that hid it, his foreskin cock was beginning to erect.

(Oh……♥ No, calm down…… Almost……, almost…… That body will be mine……♥)

　While he was thinking about that with his head dizzy from the heat and excitement of the sauna, the sound of the splash echoed, and a dense mist spread throughout the room.

“Ugh……, cough……!”

　The moment he inhales that mist, he coughed. The man is coughing as well. As it is, Satoshi coughs with his hands on the floor and grins at the sights that flashes through his mind. They were men who had swapped their bodies with Satoshi in this mist sauna. And then came──

（Oh, yes♥♥)

　A strange, pleasurable sensation that made his whole body melt. The numbing comfort made his body involuntarily relax. No matter how many times he experiences that sensation, it feels so good that it becomes a habit. He laid down on the floor, warped like a shrimp and stretched out his toes, and tasted the sensation with his whole body.

“Nmm♥ Agahhh♥♥”

　He looked around with a twitch and saw the man lying on the floor as well. He was repeating his breathing hard, and his flushed face showed an expression of ecstasy. He doesn't know what's going on──. Such a question was floating on his face.

“Oh my God, what is this……? Oh, I'm……, I'm……♥♥♥”

　Eventually, he shuddered with a yowl-like cry. His cock, compressed between the floor and his abdominal muscles, jerked and thrashed about, is spurting cum from its glans. He seemed to have let go of his consciousness, his face contorted in pleasure.

(Very erotic……♥)

　Satoshi's excitement was at its peak at the sight of such a scene. The blood in his body was boiling and his cock was pulsing with a thump. He can't take his eyes off the man lying there in his pitiful form. That big body, that stern face contorted in pain, that cock spewing hot semen from the tip of its glans in pleasure, would now become his own.

“I can't help it♥♥♥”

　The hot thing in his testicles is getting ready to come out. The cock was larger than average. Satoshi scratched his head with both hands at the sensation of blood coursing through the veins floating on its surface. His asshole aches and tingles, he writhes in agony and pleasure as if something is rampaging in his belly, and yet he shakes his hips madly, wanting to taste more.

“Oh, God, oh, God♥♥ Oh, oh, ooooh♥♥♥”

　Something that had been stirring in his belly popped out through his throat. He couldn't stop his charming voice. He moves his hips, and as something comes out of his mouth, hot, simmering semen sprays from his cock. A pitiful scream echoed through the sauna room, but it didn't matter. The muscles in his body pulsed and his hips continued to move on their own. The moment he saw the white misty haze overflowing from the man's mouth, Satoshi let out the same white smoke and let go of his consciousness.

＊＊＊

“Nn……, nmmmm……”

　With a low moan, Shingo Akutsu slowly opened his eyes. He put his hands on the wet ground to raise himself up, and his knobby, burly fingers came undeniably into view, and he couldn't help but shudder with delight.

“Wow……!”

　He let out an involuntary panting, and a sexy, thick voice reverberated through the room and into his ears. And he realizes that this time, too, the body swap by this mist sauna has succeeded. Since there are no mirrors in the sauna, his face cannot be seen, but the huge chest plate and cracked abdominal muscles spread out below him arouse Shingo's lust. The cock between his legs is soaring and pulsating, and the white pre-cum dripping from the tip of his glans never stops. Shingo's mouth twisted into a smile as he shook his big cock.

“That's amazing……”

　When he gripped his pectoral muscles, which were comfortable to rub, his big cock jumped as if in response. Shingo's body trembled as he let out a hot exhale when he grasped the wet glans in his palm.

“Oh……♥ My cock is fucking good……♥♥”

　He played with his nipples and rubbed his entire manhood, which was wet with his enduring pre-cum, making soaking sounds. The thick, rough fingers dig into the back of the corona of glans penis, occasionally scratching the back threads to stimulate them, and a gush of clear pre-cum gushes from the tip of the glans. Shingo's body, deprived by others, tingles from within, as if begging to be played with more, and he is rushed to further pleasure.

“Oh, God♥ I'm cumming♥♥ I'm gonna cum♥♥”

　Shingo's whole body stiffened for a moment, then he curled his toes and let out a loud and charming cry as he sprayed his white semen all over the floor. The ejaculation did not stop. Shingo's hips bucked wildly in response to his pulsating, twitching big cock, and he looked ecstatic.

“This is 【my】 new body……♥”

　Shingo muttered with an intoxicated look on his face. The incomparably pleasurable sensations coursing through his entire body were so overwhelming that even the marrow of his brain seemed to be debauched by the unparalleled pleasure. He would be lying if he said that the bodies he had swapped with so far had not been covered in sexual desire, but its body was truly the best.

　With a vulgar smile on his face as he stretched his nose, Shingo began to play with his cock again. Shivering from the stimulation as if his whole body had become a sexual zone, he moved his hand with single-minded devotion. As if to show off plenty of his new body, he increased the speed of his hand action as he saw his former self lying on the floor in front of him. Big cock, big body, big balls. He had ejaculated and ejaculated, nevertheless he felt his balls filling with cum.

“Ooooohhh♥♥ Cum♥ I'm cumming again♥♥♥”

　Shingo's face contorted in pleasure, and he screamed as he sprayed his cum all over the place. The cum spewed out repeatedly created a white puddle all over the floor and emitted a nose-tingling odor. The sight made Shingo even more aroused. The mere fact that a body that continues to release such thick semen is now his own naturally makes him smile.

“Hah……♥ Aah……”

　Eventually, perhaps having finished ejaculating for a moment, Shingo smiled with satisfaction and sat down on a seat made of stone. He felt the ball sack hanging between his legs twitching and wriggling, sperm being produced in it again.

　When he looked around at his whole body again, he smiled wryly and licked his tongue. A black, tanned body. Thick neck, muscles, long arms and legs. The opposite of the sportsman's slender body he had earlier, he had a strong, muscular body that had been trained through his manual labor. The healthy sweat from the sauna mingled with the sweat from the fear of being deprived of his body, giving off an indescribable odor. He sniffed up his hairy armpits and felt a sour, pungent odor, and his cock twitched and had a boner again.

“Oh, fuckin' stinky……♥ I can't get enough of it, hah……♥”

　As he ran his tongue over his still-wet armpits and licked away the sweat, Satoshi, who had been lying prone on the floor, came to his senses with a faint shriek. He opened his eyes and looked around, then his eyes widened in surprise as soon as he recognized that it was 【Shingo Akutsu】 in front of him.

“What?! I'm the other one? What's going on……!?”

　Satoshi looked down at his own body and started to panic, but Shingo narrowed his eyes, grabbed Satoshi by both armpits, and pulled him closer.

“Hey bro♥ Why do you sound so flustered?”

“Don't pretend to be me! What in the world is that way you talk……?”

“What? You're the one who's playing around. You can tell by looking at it, right? I'm……, 【Shingo Akutsu】. Hehe……♥”

　Shingo looked down at Satoshi, who raised a puzzled voice, and smiled a smile that looked like he was truly enjoying himself. The moment Satoshi saw that expression, a shiver went down his spine. But it was only for a moment, and soon his anger overtook his fear, and he angrily punched Shingo in the face. But──

“Hey, don't do anything dangerous, bro.”

　His hand was easily grabbed and twisted, and Satoshi screamed and fell to the floor. It was only natural, since there was a considerable difference in their physiques.

　Looking down at Satoshi, Shingo put a sadistic smile on his face and sat down vigorously on the seat.

“Ha ! ha ! ha ! I'm sorry to tease you, Mr. Akutsu. By the looks of it, you don't seem to know how this mist sauna system works, do you?”

“……Sauna system? What are you talking about? Just hurry up and put my body back!”

“You're so impatient…… There is no need to be in a hurry. In this sauna, a thick mist is produced once an hour, and the bodies of those who are exposed to it are swapped. So, if both of us are exposed to the mist at the same time in another hour, we will return to our original bodies.”

“I don't know what the hell you're talking about……!”

　Shingo smiled at Satoshi, who sounded puzzled, and slowly extended his hand. He then grabbed his upper arms and pulled them lightly toward him..

“Hey……! What are you doing……?”

　Ignoring Satoshi, who is upset by Shingo's sudden action, Shingo moves his face closer to Satoshi's as he lets out a hot breath.

“Hey, Mr. Akutsu. How is my body? The body you were using just a moment ago is right in front of you……?”

“Whoa……, huh……?”

　Satoshi looked puzzled at the words asked by Shingo. 'What is this guy talking about? Why is he asking me such a question?' Even as these questions run through his mind, the face of 【Shingo Akutsu】 fills Satoshi's field of vision. The smell of sweat, too masculine, erupting from his entire body. Satoshi frowned at the body odor that even smelled like a beast because 【Shingo】 had not washed his body before entering the sauna. But the next moment, his mouth was overlaid with his own──

＊

“Hmmmm♥♥”

　As soon as the slick sensation ran through my mouth, I opened my eyes and stiffened. Am I kissing a man? And that body of his is my body from a moment ago──

“Nchu……♥”

　The moment I saw the entranced look on 【Shingo Akutsu】's face, something inside me popped. I was so excited that all my fears and aversions to this unusual situation were blown out of my mind, and I unconsciously inserted my own tongue into the mouth of the other man in front of me. My mind went blank with the pleasure that seemed to pierce my entire body, and a euphoric feeling that I had never felt before shot through my brain.

“Ahh……, ah……♥♥♥”

　I, who have lived as a strong man since my school days, am being pushed down so easily and having my lips taken away by a man who is much bigger than I am. And the other person is a man whose body I used to be. Whenever I realize this fact, my cock gets harder and harder, and the pre-cum begins to overflow from the glans.

“Smooch♥♥ Hmm♥ Mwah♥♥”

　We both devoured each other's deep kisses, our tongues flicking and exchanging saliva. The smell of their male body odor and the fishy spit clinging to my tongue numbed my brain with pleasure.

　I had never experienced anything like this before. I have had sex with countless women in my life, but this kiss is more intense, more sensual, and more reassuring than any I have ever experienced with anyone else. My brain was beginning to be dominated by the desire to be fucked by the 【tough guy】 in front of me.

“How about it, Mr. Akutsu? I think it's time you started having sex with me, don't you? You are now using my brain, which has been held by sturdy guys many times before. I'm sure this body must look very attractive to you……? In an hour, we'll both be back to our original bodies anyway, and that body will be mine again. My body is the one whose asshole will be expanded by this cock. Your body will not get dirty at all, so why don't you try man-on-man sex? If you miss this opportunity, you will never experience it again……♥”

　The moment he told me this, as if whispering in my ear, I felt something in my head crumble with a sound. If it had been me before, I would never have accepted such an invitation. 'Man-on-man sex? I'm not a homosexual, and I don't want to be fucked my ass! I would have said so, and rejected his offer. But now, I couldn't imagine refusing this invitation. Because──, that cock dangling in front of me looks so good, so good, I can't resist it!

　I sucked 【Shingo Akutsu】's cock into my mouth and began to suck it up and stimulate it hard. At the same time, I rubbed his big swollen balls and served him wholeheartedly. The sight of the blow jobs that 【Satoshi Tokura】 had done many times before flashed back in my mind, and my body naturally moved.

“Hmmm……♥♥ You're good at sucking cock, Satoshi……♥♥”

　I devoured the man's── and my former self's cock with a passion while my nostrils were assaulted by the smell of sweat and steam. I went back and forth over and over again on his saliva-slick cock, licking up the underside of his cock to the glans. Each time, the rich taste of male cock in my mouth excited me to the point that I felt as if my heart was going to melt.

“Ahh……, sooo good♥ Satoshi♥ Keep it up.”

　【Shingo Akutsu】 groaned low with a look of ecstasy on his face. I continued to move my hand even harder, my arousal fueled by those words.

(Oh, shit! Why……!)

　While swearing in my mind, my tongue was carefully licking up from the guy's glans to his frenulum of prepuce of penis. Before I knew it, I'd gotten an erection too, and I could feel the tip of my cock flooding with pre-cum. It's bitter, salty, and fucking disgusting, but I can't believe how delicious it tastes……! I kept sucking it like crazy. Finally, I couldn't hold back any longer, so I covered the guy and invited his cock to come inside my asshole.

──Slurp, slurp……, thrust

“Noooooo♥♥♥”

　I ejaculated with a wild yell. My Ahegao gets worse as I hear the lewd sound of his cock being swallowed up inside my asshole. I had never used an ass before, but as if I had been using it for years, my asshole easily took his huge cock up to the root.

“Oh-ahh♥ Hey, you're being very aggressive, Satoshi……♥♥”

　As if prompted by 【Shingo Akutsu】's whispers, I slowly began to move my hips. At first I was afraid to move my hips, but then the intensity of the movements increased, and before I knew it I was shaking my own hips and letting his cock play with my asshole. I found myself wiggling my hips and plowing my own asshole with his cock, making obscene sounds as I moaned and moaned.

“Ooooh♥ Ooooh, cock good♥♥ Your cock ♥♥♥”

　I…… am in ecstasy with a man's cock in my asshole……

　I've turned into a perverted homo. I'm so pathetic and ashamed that I'm about to cry. But I want more pleasure. My head is going crazy. My half-erect cock is flailing around left and right, spewing clear juices.

　I want to be fucked more and more violently──, my head is filled with such desires. I even felt as if I had become a slutty bitch when 【Shingo Akutsu】, smiling with a relaxed smile on his face, was fucking my asshole. I'm sure he must think it's hilarious to see me, splattered with sweat, snot, and drool, desperately devouring the pleasure.

　But none of that mattered to me now. Kissing a guy who gets his ass dug by a big cock and does it until his mouth is all chattering and drooling is the best feeling in the world. More! Fuck me in the ass more!

　Instead of yelling that, I clamped 【Shingo Akutsu】's cock tightly in my ass while sticking my tongue out and asking him to kiss me on the mouth. As if in response, the guy also sucked on my lips and twirled his tongue with mine. We continued to exchange saliva and tongue with each other.

(Oh……, oh my God……, I'm about to cum……!)

　I involuntarily shuddered at the prospect of a mind-boggling orgasm. At the same time, 【Shingo Akutsu】's cock, which was deeply penetrating my asshole, pulsed violently.

“Whooooa! I'm gonna cum…… with this muscular dad's big cock♥♥”

──Bbullllllll!! DOPP!! Bukkukk! B-B-B-Buhhhhhhhh!!!

　The man lets out a roar that shakes the air, and a large amount of hot semen pours into my asshole. The sensation makes my whole body convulse and I ejaculate profusely. The pleasure was so great that I almost lost consciousness, but I still squeezed my ass and did not let go of 【Shingo Akutsu】's cock, clenching my ass as if to squeeze every last drop out of it.

(Oh……♥ Amazing……, sex with a man feels so good……♥♥)

　A man's──, and a cock that had been dangling between my legs earlier. I was filled with a sense of accomplishment and happiness that welled up from the bottom of my stomach, even though I had been injected with a load of cum that had shot out of the tip of his cock.

　By the time the long ejaculation finally came to an end, my whole body was covered in sweat and cum. 【Shingo Akutsu】's thick, sticky semen was flowing back from my ass. Looking down with an ecstatic smile at the sight of the man who had finally become the man I loved──, 【I】 ejaculated again and again.

＊

　A sexy moaning sound comes out of my mouth. When I was 【Satoshi Tokura】's body, all I did was get fucked, but now I was the one getting fucked. The act of violating a man's asshole, which I had not tasted in a long time, made my whole body tremble. Just the fact that I am fucking a man's asshole with my stiffening cock is enough to arouse me to the point where I feel like I am about to come.

“Oooohhh, Woo-hoo♥♥ Oh my God, it's so good! It's so tight, I can't stop moving my cock♥♥”

　It was funny and humorous──, and unbearably exciting to see a man who had lost his body to me frantically shaking his ass at me.

　I never thought that a man who had once had sex with numerous women would be so lewdly exposed to 【me】……! My new cock is rampant inside his asshole. My cock, warped and hard, scratches and stimulates the man's bowels. I had long since forgotten how good it felt to have a cock in a man's asshole. The feelings and sensations that had been missing from my life came back to me as I fucked his ass.

“Agaahhhh♥♥”

　A man who has 【Shingo Akutsu】's cock inserted up to the root in his asshole gasps with a pained voice. The sound of his voice makes a black desire well up in the depths of my heart. I want to fuck him more! I want to make him mine!!

“Cum♥♥ I'm going to cum at my first homoerotic fuck♥♥♥”

　I hugged my former body and fucked my cock deep into his ass. Instantly, his intestinal wall tightens around my cock. The thick, heated walls of his meat covered my vital part to the utmost limit, and there was no way I could hold back any longer.

“Whooooa! I'm gonna cum…… with this muscular dad's big cock♥♥”

──Bbullllllll!! DOPP!! Bukkukk! B-B-B-Buhhhhhhhh!!!

　Cum spurts out of my cock as I shoot it deep inside his ass. I laughed as I shot a huge load of cum inside him, drooling out of the corner of my mouth.

(Hah……♥ 【I】 am straight, but now I'm cumming inside a guy's ass. It feels so good to fuck a guy using this married man's body……♥♥♥)

　Then I continued to fuck 【Satoshi Tokura】's body until the one-hour time limit was up.

　I was in the position of raping, but the person in front of me was my former body until just now, so I could feel like I was being raped and killed two birds with one stone. I am sure that my face, now that I have become more manly, is getting relief and smile. After all, the man in the form of 【Satoshi Tokura】 is also laughing with a vulgar face while gurgling cum from his asshole, which has been repeatedly creampied by me. I can feel that he is already lost in me to the marrow of his bones.

“Hah……♥ Sex with you was great, Satoshi. It's been a long time since I've tasted a man's asshole, but it's still very special♥”

　I wiped our semen-soaked body with a towel and stood up, slapping my knees and putting my hand on the door of the sauna.

“What the……?! Wait a minute! Didn't you promise that after an hour we'd swap our bodies back?”

“Hmm? Was it? Sorry, I don't remember……, forgive me♥ I want to enjoy this body more. You, the original owner, know what I'm talking about, don't you? I want to fuck other guys' asses with this cock, and I want to fuck my beloved wife's pussy with it♥♥”

　When I said so with an artificial smile on my face, 【Satoshi Tokura】's face turned pale. The face of despair──, I can't resist it! I opened the door and left the sauna while suppressing my deflated cock from becoming erect again.

＊＊＊

“Oh, no……”

　A man in the shape of 【Shingo Akutsu】 left the sauna. I tried to go after him, but he had fucked me so hard in the asshole that I was unable to stand up. I look at the hands of the wall clock and see that it is about to stick the time, an hour since then. A mist would occur──. But the person I wanted to swap the body back with is gone. If the efficacy of this mysterious sauna is well known to everyone, no new customers will come in unless they are very good. What else could I do but to continue to live in this body? It was then that I was in such a gloomy mood.

“Oh, it's empty!”

“Lucky! Come on in, you guys!”

　As if to counteract my despairing thoughts, I heard a bold and vigorous voice coming from the door. I looked up and saw several strong men standing there. There must be a Sport University nearby, and they were probably students there. All of them had muscular bodies covered with muscles and their faces were fearless, giving the impression of sportsmen.

(Thank God……♥ One of their bodies will be mine……♥)

　All of them are as manly and attractive as the previous 【me】, and I would have no complaints about any of their bodies.

──The time has come.

　The sound of the splash echoes, and a dense mist spreads over the entire room. Looking at each other with puzzled expressions on their faces, the young men are ejaculating, spitting out a white misty haze from their mouths. Watching their dismay, I felt a sense of titillation. Which of those men would my body be swapped with from now on? With this excitement in my heart, I also spat out the same misty haze and splashed thick, simmering cum all over the place.
