Ghost Override (Pixiv Fanbox)

　The year was 20XX──.

　Science and technology advanced at a breathtaking pace. Things that had seemed like nothing more than fantasy only yesterday were becoming reality one after another.

　Astronauts had already set foot on Mars, and an orbital space station was still under construction. Medicine, too, had progressed at an astonishing rate. Countless illnesses once thought incurable had been eradicated, leaving only a handful that still defied treatment. All of it had been made possible by the rapid evolution of a single technology.

　Countless delivery drones crisscrossed the skies above the city. Paying for anything with the chips implanted beneath people's skin—and backing up their memories to the cloud—had long since become part of everyday life.

　The evolution of AI had been nothing short of extraordinary. By now, people had entrusted virtually all of their work to intelligent machines. All that remained was to spend their days however they pleased while the lives they desired were produced for them automatically.

　It was in this age that a single company unveiled a product unlike anything the world had ever seen. 【Alter Device】, the industry giant that dominated the wearable technology market, announced its latest creation. It was far more than just another smartwatch. Its name was 【Ghost Motion】.

　At first glance, its design was remarkably simple. Yet beneath its unassuming exterior lay something unlike any AI the world had seen before. The device's built-in lifestyle support AI—nicknamed 【Ghost】—went far beyond the role of a mere digital assistant.

　Once activated, the user's consciousness was transferred entirely into the 【Ghost Motion】 device itself. From that moment on, Ghost assumed complete control of the user's physical body, acting in their place in the real world. It could prepare meals, exercise, and even handle work. As long as the task involved routine physical labor or ordinary desk work, Ghost was fully capable of performing it on the user's behalf.

　While the user slept, Ghost handled everything. It managed the body flawlessly, ensuring that when the user awoke, not the slightest trace of fatigue remained. If anything, they felt more refreshed than ever before.

　The moment the company announced that 【Ghost Motion】 would enter beta testing, the response was overwhelming. Within just a few hours, applications had surpassed several hundred thousand. Government agencies from around the world rushed to secure places, joined by many of the world's leading researchers. Before long, the announcement had sparked a frenzy on a truly global scale.

＊＊＊

"Huh? Tatsuya…… Have you lost weight? Actually…… no. You look seriously jacked."

　Satoru Kanaya blurted out the moment he ran into Tatsuya Fujita in the hallway. Tatsuya worked in a different department, but the two had attended the same university, where Tatsuya had been Satoru's junior on the American football team. Since they worked for a sporting goods manufacturer, the office was full of former athletes.

　But after graduating from college, unless someone continued competing professionally or trained with the same intensity, everyone changed in much the same way. Muscle gradually faded, waistlines thickened, and appetites never seemed to shrink. Before long, even the fittest bodies began to soften. That was simply the natural course of things.

Up until about a month ago, Tatsuya had been no exception. He'd put on enough weight that the buttons on his dress shirt always looked ready to pop. Yet now, standing before Satoru, he looked like an entirely different person. In the span of just a single month, his body had undergone a dramatic transformation.

"Dieting……? Or have you been working out? But neither of those was ever your thing, was it?"

　If anyone had asked Tatsuya about his hobbies, he would have answered without hesitation: stuffing himself with food. Back in college, the only reason he trained at all was because the coaches forced him to. He had dragged himself through every workout looking as though he were on the verge of tears. So once he became a salaried employee and no longer had anyone pushing him, it hadn't taken long for the weight to pile on.

　And yet, Tatsuya's physique was now every bit as impressive as it had been in college—if not even better. His double chin had vanished, his jawline was sharp, and his complexion looked healthier than ever. Even beneath his suit, the broad contours of his shoulders and arms were impossible to miss. The belly that had once bulged conspicuously beneath his shirt had flattened completely.

"Haha…… It's all thanks to this little device, Senpai. You know—the one everyone's been talking about."

　With a grin, Tatsuya held out his wrist and lovingly ran his fingers over the device fastened around it, his expression almost entranced.

"The AI works my body while I'm asleep and does all my training for me! Then I wake up looking like this. It's awesome! It even manages my diet, plans perfectly balanced meals, and cooks them automatically. My gut health's never been better, and I'm regular every single morning. Hahaha!"

　As Tatsuya excitedly rattled on, irritation welled up inside Satoru. Meanwhile, Satoru felt as though the ever-growing mountain of work on his desk was about to crush him. Seeing Tatsuya speak with such carefree enthusiasm—as if stress simply didn't exist—grated on his nerves.

"Damn…… I'm jealous. That's the new 【Ghost Motion】 smartwatch, isn't it? I signed up for the beta test too, but I didn't make the cut. So you actually got picked as a tester. Then again, you've always had ridiculous luck. ……Still, while that thing's running, doesn't the AI just take over your body and do whatever it wants with it? Isn't that kind of dangerous?"

　Satoru folded his arms and frowned. Jealousy was all he could feel. At this point, he wanted to hear anything—anything at all—that might cast even the slightest shadow over the device. Tatsuya simply laughed.

"Nah, not at all! It's completely safe! I mean, my body just gets healthier on its own. It's ridiculously easy, totally stress-free. While I'm asleep, the AI works out for me, and I wake up a little closer to my ideal physique every day. And it doesn't stop there. It even takes care of all the annoying stuff, like cleaning my apartment. Seriously, Ghost is the best. Thanks to it, I lost ten kilos in just one month. There's no way I could live without it now!"

　Watching Tatsuya gently stroke the smartwatch with the blissful expression of someone admiring his own beloved child, Satoru couldn't help feeling genuinely envious. There was just something about new gadgets that appealed to men, and when someone enthusiastically demonstrated a product that actually lived up to the hype, jealousy naturally began to well up inside him.

（Maybe I want one too……）

　The thought had only just crossed Satoru's mind when Tatsuya spoke.

"If you'd like, I could put in a good word for you at 【Alter Device】. I heard they're planning to expand the beta program soon, and they asked me to keep an eye out for trustworthy candidates with a background in sports."

　At Tatsuya's suggestion, Satoru's eyes lit up.

"Seriously? I'd really appreciate it!"

　His jealousy vanished as if it had never existed. Satoru changed his tune in an instant, his excitement soaring so high that he spent the rest of the day unable to focus on anything else. Watching Satoru's delighted reaction, Tatsuya allowed himself a quiet, knowing smile.

＊

"Oh, it's here!"

　Opening the package locker in his apartment building, Satoru picked up the box that had arrived from Alter Device and hurried back to his apartment, barely able to contain his excitement. The moment he locked the front door behind him, he made a beeline for the living room. Tossing his suit jacket and slacks carelessly onto the floor, he eagerly tore open the package.

　He had already seen Tatsuya's, so he knew what to expect. Sure enough, inside the box was a wristwatch that looked almost no different from an ordinary smartwatch.

"Hmm…… So this is the famous thing everyone's been talking about……"

　He strapped the watch onto his wrist and tapped the display.

　《Full Auto》.

　When activated, the user's consciousness would fall asleep while the AI took over, handling everything from exercise and cleaning to grocery shopping and meal preparation. Alternatively, each function could be toggled on or off individually. For example, disabling the 《Meal》 option would allow the user's consciousness to return whenever it was time to eat, so they could enjoy whatever food they wanted.

　For his first day, Satoru decided to select 《Full Auto》. According to Tatsuya, 【Ghost Motion】 would even take care of chores like cleaning and tidying up on its own, so he figured it was the perfect opportunity to put those claims to the test. The next instant, his consciousness faded into darkness.

"Mmm…… Already morning?"

　A pleasant melody chiming from the smartwatch gently woke Satoru from his sleep. He sat up in bed and stretched both arms high over his head. A faint soreness lingered throughout his body, but it was far from unpleasant. If anything, it felt like the satisfying fatigue that followed a healthy workout.

"……Right. Bathroom first……"

　Feeling the urge, Satoru hurried to the bathroom. When he finished, he glanced into the toilet bowl and found a thick, perfectly formed, banana-shaped stool. That alone was enough to tell him that the previous night's meals had been exceptionally well balanced.

"This is insane, Ghost Motion!!"

　After just a single day of using it, Satoru had become completely captivated by 【Ghost Motion】. From that day forward, he used 【Ghost Motion】 every day.

　There were times, however, when he wanted to enjoy dinner on his own. On those evenings, he simply turned off the 《Meal》 function so he could choose and eat whatever he liked.

　One week after he had started using the device, the results were undeniable. In only seven days, Satoru had lost two kilograms. Better yet, his body fat percentage had dropped while his muscle mass had increased.

"Tatsuya, this smartwatch is incredible! Seriously, thanks for recommending me!"

　Seeing Tatsuya again for the first time in a week, Satoru beamed with a newly sharpened, healthier face as he enthusiastically slapped both of Tatsuya's shoulders.

"I'm glad you like it, Senpai. That makes me happy too."

　The two shared lunch together in the company cafeteria.

(Just a little longer…… Sorry, 【Senpai】. You've worked so hard to get that body back into shape, but before long…… 【we】're going to take it for ourselves.)

　Watching Satoru's back as he headed off to work that afternoon, Tatsuya once again curled his lips into a sly smile.

＊

　Another two weeks passed. Every morning, checking his reflection in the mirror had become part of Satoru's daily routine. At first, the changes had been subtle—Maybe I've toned up a little?—but with each passing day, the transformation became more and more obvious.

　One month after he had begun using 【Ghost Motion】, he had lost a total of five kilograms. Yet the body staring back at him in the mirror had actually become thicker and more powerful. His chest had broadened until the buttons of his dress shirt looked ready to burst, and his arms had grown noticeably larger. He had regained the physique he once had as a college football player—no. It had clearly surpassed even that.

"No way……"

　Back when he had been going to the gym, no matter how hard he trained, he had never seen such dramatic results in so short a time. Even with three workouts a week and strict diet management, he could only just manage to maintain the physique he had.

　Now, everything was different. While he slept, the AI took care of every tedious chore, and his body steadily transformed without any effort on his part. Better still, it was becoming far more than merely muscular. He was approaching the physique of a competitive athlete—and if he wanted to, it seemed entirely possible that he could eventually reach something close to a professional bodybuilder's level. Even around the office, his transformation had become impossible to ignore. More and more of his coworkers were stopping him to comment on how much his body had changed.

"Hey, Kanaya, haven't you gotten seriously bigger lately?"

"Did you switch gyms or something?"

"Your face has slimmed down too. You're looking pretty handsome."

　Every compliment left Satoru feeling both embarrassed and quietly exhilarated. A deep sense of superiority welled up inside him. After all, all he had done was sleep. And yet, he had obtained the kind of physique that everyone envied.

　The jealousy he had felt when he first saw Tatsuya's transformed body now seemed like a distant memory. By this point, his own physique had completely surpassed the one Tatsuya had shown him that day.

　Standing before the mirror, Satoru struck a series of poses. He puffed out his chest, tightened his abs, and curled one arm to flex his biceps. Perfect…… But with 【Ghost Motion】──.

(I can become even more perfect. As long as I have 【Ghost Motion】, I can achieve my ideal body without feeling even the slightest bit of stress……)

　By now, Satoru's physique had changed so dramatically that he was practically a different person from the man he had been just a month earlier. Although he now weighed five kilograms more than he had in his college days, his body fat percentage had dropped into the single digits, while his muscle mass continued to climb to new personal records.

　Off-the-rack clothes no longer fit his expanding frame. He had already replaced every one of his suits and dress shirts twice with custom-made ones. The unexpected expense had stung, but by now, he couldn't have cared less.

(Tatsuya…… Thanks for introducing me to this. This feeling……, it's incredible.)

　Gazing at the perfectly sculpted body reflected in the mirror, Satoru wore an expression of pure bliss. Completely unaware that, before long, that body would no longer belong to him──.

＊

"Phew……♥ Satoru-senpai, you've really built an amazing body. That look of a thin layer of fat over thick muscles—it's sooo sexy♥ And your asshole too—it's incredibly tight, hot, and slippery……"

"Mmmm, that feels so good, Tatsuya! Thrust deeper……♥♥ Ah, right there! That's it♥"

　Under the dim lighting, two sweaty, naked, muscular men were lost in the heat of the moment, slamming their hips together fiercely. The bedsheets were soaked through with their sweat and bodily fluids, and the room was filled with a stifling, musky scent.

　One was Tatsuya—a former college football player with a rugged, heavily muscled physique forged through years of grueling training. His broad chest, thick arms, and sharply defined abs spoke of raw power. Beads of sweat trickled down his body, sliding through the valleys between his muscles, lending him the untamed aura of a wild beast. The other was Satoru.

　After using 【Ghost Motion】 for more than a month, Satoru's body had become even more refined, boasting a level of perfection that rivaled a masterpiece sculpted by a master artist. Every muscle stood out with striking definition, yet together they formed a perfectly balanced, natural physique, enhanced by an almost mesmerizing elegance. It was, without exaggeration, the ultimate embodiment of the beauty of the human body. But now, despite his perfect physique, he was being fucked by a man's cock and letting out cries of ecstasy.

　The two embraced, seeking each other out like beasts, driven purely by desire. When Tatsuya pulled his hips back sharply and then thrust forward in one powerful stroke, Satoru's massive body shook violently, and a pitiful moan—the kind he never usually uttered—escaped his lips. Satoru's rugged face contorted with pleasure; saliva overflowed from his slack, open mouth, trickling down his Adam's apple and onto his chest. Seeing him so defenseless only fueled Tatsuya's excitement even more.

"Ahh, give me more! Harder! Break me with your huge cock! Nngghhhh!!!! I'm gonna cuuuuuum!!!"

　To an outside observer, he was the very embodiment of a lecherous female pig addicted to sex. He was swaying his hips lasciviously, letting out raucous moans as he eagerly devoured Tatsuya's cock. Yet his body moved with a mechanical precision, always providing him with just the right amount of stimulation. Yes, it was as if he were being controlled by something──.

"I'm gonna cum, Senpai!! Your ass is squeezing me so hard…… Ahhhh, I'm cumming♥♥♥"

　Tatsuya's scrotum contracted, and the hot semen that shot out of his urethra forcefully filled Satoru's intestines. The pulsing of his ejaculation made Satoru's asshole tremble in rapid spasms, and the overflowing semen trickled down the cleft of his ass.

　At the same time, Satoru arched his upper body dramatically and fired a powerful stream of semen from his cock. The semen flew in an arc, splattering all around them and coating both of their bodies even more thoroughly.

"……Ghost, command mode."

　Though both of them were panting heavily, as soon as Tatsuya issued the command to Satoru, he immediately became expressionless and straightened his posture. The sweat running down his bulging muscles glistened seductively as it reflected the lighting.

"Understood, Master."

＊

　Throughout the sex, Satoru's body remained in 【Ghost Motion】's active mode. Under normal circumstances, Ghost would never obey commands from anyone other than its registered user, Satoru. Furthermore, if it detected a situation in which the user might engage in sexual activity or any similarly intimate act without prior authorization, it was programmed to immediately awaken the user's consciousness by force.

　So why was Satoru's Ghost following Tatsuya's commands? Because Tatsuya had infected Satoru's 【Ghost Motion】 with a virus.

　Ordinarily, Ghost faithfully carried out Satoru's wishes, exercising in his place and assisting with every aspect of his daily life. But once Tatsuya rewrote its recognition of who its master was, Ghost accepted his commands without question, becoming a loyal servant at his beck and call. Offering up 【Satoru Kanaya】's body to him──.

"Thank you for training me to better suit Master's preferences today as well."

　Satoru's Ghost, his cheeks flushed and a white, cloudy fluid still dripping from the tip of his glans, mechanically offered his thanks. Then, kneeling down on the spot to clean Tatsuya's cock, he took the massive penis into his mouth without hesitation and began to pleasure him.

"You played the role of 【Satoru Kanaya】 perfectly again today, Ghost! Your asshole is getting better and better, and your shy, straight-guy act is spot-on♥ ……So, what do you think of Satoru-senpai's body?"

　Tatsuya looked back and called out to a man sitting on a chair in the corner of the room, jerking off. He was a short, ugly-looking guy whose entire body was covered in thick fat, with a bulging belly. He looked like the kind of person who would never have crossed paths with athletic guys like Tatsuya and Satoru. On top of that, he had a small, true phimosis, and his foreskin-covered cock was shriveled up—even when aroused, it was no bigger than a thumb.

　The man—Kozo Matsumoto—who was dripping sticky semen from such a pathetic cock answered Tatsuya while letting out a hot sigh.

"He's perfect, Tatsuya♥ With that tough, straight-guy look on his face and a muscular body that's sure to be a hit with gay guys…… From his plump, manly chest to his chiseled abs and even the size of his ass—everything about him is just right for my 《New Body》…… I can't wait to possess his body……♥♥"

　The ugly man's bloodshot eyes gleamed with excitement, and his bloated belly rose and fell with every heavy breath he took. Tatsuya gave a satisfied nod before issuing a command to the Ghost controlling Satoru's body.

"Good. Then let's get started…… with the body-switching show♥ Ghost of Satoru, remove the smartwatch containing Satoru's consciousness."

"……Understood."

　Ghost gave a respectful nod and removed the smartwatch from Satoru's wrist. Under normal circumstances, 【Ghost Motion】 was programmed so that the device could never be taken off while it was active. But thanks to the virus Tatsuya had planted, even that safeguard was effortlessly bypassed.

　Watching the scene unfold with a grotesque grin spreading across his face, Kozo activated the 《Full Auto》 function on the 【Ghost Motion】 strapped to his own wrist. Instantly, his body entered AI-operated mode. His fat-laden frame moved with mechanical precision before turning its gaze toward Tatsuya.

"Ghost of Kozo Matsumoto, remove the smartwatch from your wrist and hand it to me!"

　Kozo's Ghost acknowledged the order as well. Without the slightest hesitation, it removed the 【Ghost Motion】 from Kozo's wrist and handed it to Tatsuya. Just like Satoru's device, Kozo's 【Ghost Motion】 had been infected with the same virus, leaving his Ghost just as obedient to Tatsuya's commands.

　Taking the 【Ghost Motion】 containing Kozo's consciousness, Tatsuya handed it to Satoru's Ghost and ordered it to fasten the device onto Satoru's wrist. Once it had done so, he instructed it to deactivate AI-operated mode. Satoru's Ghost gave a silent nod, carried out Tatsuya's orders exactly as instructed, and closed its eyes.

　The very next moment, Satoru's powerful body gave a violent jolt.

＊

　His thick muscles rippled as sweat began pouring from every inch of his body. Then 【Satoru Kanaya】 slowly opened his eyes. Raising his broad, calloused hands before his face, he blinked several times, studying them with careful fascination.

　Next, he began running those hands over his own body, as though confirming something. He kneaded his massive pectorals, traced the ridges of his abs with his fingertips, slapped his thighs, and squeezed his buttocks in a firm grip. Slowly──, savoring the sensation of his fingers sinking into solid muscle.

　At first, his expression was blank, as if he had only just awakened. Gradually, however, color returned to his face. His once-sharp, masculine features melted into a slack grin, and his breathing grew heavier.

"Ooh♥ Whoaahhh♥ This is my new body… so sexy! Ahaha…… my voice is deep and cool, too~♥♥ These huge male boobs feel so bouncy when I touch them…… mmm, my nipples get rock-hard just from a little teasing♥"

　Satoru's flaccid penis swelled instantly; the thick pole, with veins bulging beneath the skin, throbbed and pulsed, and pre-cum began to drip copiously from the tip.

"You seem to like your new body, Kozo──no, Satoru-senpai♥"

"Yeah♥ This body is fucking amazing, Tatsuya!! Thanks so much♥♥ Just realizing that this body is mine feels so good it's driving me crazy……♥ My cock is black, and it's awesome that it gets this big just from getting a little turned on……"

　Having fully integrated his soul into the body of 【Satoru Kanaya】, Kozo sat down on the bed, gripped his erect cock, and began stroking it vigorously. A fishy smell wafted through the air with each movement of his hand, and pre-cum overflowed from between his fingers.

"Ooooh……♥ It feels so good! The thickness when I grip it in my hand—the shape and length are just perfect…… Even though I just came a little while ago, I'm about to cum again just from a little stroking♥♥ Haa……, I can't hold back anymore! Let me thrust this huge cock into your asshole, Tatsuya……♥"

"Yeah! I've been waiting for you to say that, Satoru-senpai♥♥"

　The two men, both with powerful, muscular bodies, sank once again into a whirlpool of pleasure, drenched in sweat and bodily fluids.

＊

"Hey, old man! Wake up!"

　Satoru awoke to a deep, husky, distinctly masculine voice that sounded strangely familiar. His eyelids felt heavy, and his mind was clouded. Normally, after spending the night with Ghost Motion activated, he would wake up feeling refreshed, his body light and his thoughts crystal clear.

　But today was different. It felt as though he had been forced to wear a suit of armor, every inch of his body weighed down. And that voice just now... whose was it?

　His vision gradually came into focus. Anxiety creeping into his chest, Satoru lowered his gaze. What he saw was a pair of sagging, fat-laden breasts and a massive belly protruding far in front of him. His arms and legs were no longer firm with muscle, but soft and flabby, weighed down by layers of fat.

　To top it all off, there was his small, uncircumcised penis, almost completely hidden by his belly fat. For some reason, a clear fluid was oozing from the pink tip that was barely peeking out.

"Wh-what the hell!? What is this!? Wait, what's going on with my body……!?"

　He frantically looked around. It was Satoru's room as usual, but the air was thick with a suffocating masculine scent, making the scene feel eerie. On top of that, there were two men on the bed, embracing each other and kissing repeatedly. The powerful male symbols between their legs were already at full attention.

"Tatsuya? What are you doing in my apartment……? And, m-【me】?! Why the hell am 【I】 there!?"

　Satoru trembled uncontrollably from the shock. His heart pounded violently, and his throat went dry. It was strange enough that Tatsuya was in Satoru's home, but even stranger was the man sitting next to Tatsuya—it was 【Satoru Kanaya】.

　His hair was cropped short, and his features were unmistakably masculine. Yet the expression on that face was twisted into a wicked, taunting grin—a look Satoru had never once seen himself make. Panic tightened its grip around his chest.

"What the hell are you talking about, ugly old man? I'm in my apartment. What's so strange about that? If anything, you're the one who's got issues, breaking into someone else's place buck naked."

　The man with Satoru's face whispered the words in a mocking tone. His body had been forged through years of college football and refined to near perfection by 【Ghost Motion】. Now, that magnificent physique stood over Satoru, looking down on him with a sneer.

"Looks like a perverted old man who breaks into other people's homes deserves a little punishment, doesn't he, Senpai? Ghost of Kozo Matsumoto, enter Semi-Awake Mode."

　The moment Tatsuya gave the command to the 【Ghost Motion】 strapped to Satoru's wrist, Satoru's body gave a sharp jolt. A heartbeat later, his expression went completely blank, and he began obediently carrying out Tatsuya's orders.

"Yes, I understand, Master. My name is Kozo Matsumoto. I'm a 45-year-old gay man who jerks off every night while fantasizing about muscular guys like you, Master."

　Kozo's Ghost introduced himself with a blank expression and a monotone voice, then immediately got down on all fours in front of his master, Tatsuya, and sucked his cock without hesitation.

(What the hell! I don't want to suck a cock!!)

　Satoru tried desperately to resist, but his body wouldn't move a single millimeter against his will. With every suck on Tatsuya's magnificent, cum-covered cock, Satoru's breathing grew ragged and his eyes lost focus. His head moved back and forth in a rhythm as precise as a machine, his tongue licking all over Tatsuya's glans. Those movements were clearly not of his own volition. Yet, he was gradually overcome by the sensation that he was the one actively doing it.

"I'm gonna punish you too, old man! I'll bring down the hammer on your filthy asshole with my huge cock, so be grateful and enjoy it♥"

　【Satoru Kanaya】 moved behind Satoru with a beaming smile. The massive cock in his hand is rock-hard, its glans swollen to a dark red and bulging. That weapon-like object was pressed against the well-used anus of 【Kozo Matsumoto】.

(S-stop it! I'm not gay!!!)

　Though his mind and body were in a state of desperate dissonance, his asshole seemed to have long since been ready to accept the cock, and it slid right in.

＊＊＊

　A week had passed since Kozo took over Satoru's body. With 【Ghost Motion】 supporting him, he had completely settled into his new life as 【Satoru Kanaya】. He interacted naturally with his coworkers, fit right in with their athletic, high-spirited workplace culture, retained the trust of his superiors, and remained well-liked by his junior colleagues. Everything was going exactly as planned.

　To the outside world, he was a cheerful, capable professional. Behind the scenes, however, he and Tatsuya repeatedly summoned the pitiful Satoru—now condemned to live as an ugly, middle-aged gay man—to the apartment, where they continued to toy with the body that had once been his. Most of the time, Satoru's body was controlled entirely by 【Kozo Matsumoto】's Ghost, with Semi-Awake Mode activated only during the sex. Deep inside, Satoru was surely screaming in despair, struggling with everything he had to resist.

　And yet, under the Ghost's control, his body behaves just like 【Kozo Matsumoto】 should, turning him into a bitch greedily craving cock.

　Kozo loved watching Satoru like that. He felt a little sorry for Satoru, but the thought that he had possessed 【Satoru Kanaya】's magnificent physique and was now using the original owner as a toy sent shivers down his spine.

"【Satoru】-kun, pour more of your cum into my asshole……♥♥"

"Come on, here we go, 【Kozo】-san! I'm gonna thrust so hard I'll break you, so make sure you catch every drop of my cum!"

　Kozo let out a manly roar and drove his hips upward even more violently. His massive cock thrust deep into Satoru time and time again, and with each thrust, Satoru let out a moan of ecstasy. Satoru's anus skillfully stimulated Kozo's cock to feel good, guiding him toward climax. With movements as precise as a machine──.

"Ooooh, I'm about to cum, 【Kozo】-san! I'm cummingggggg♥♥♥"

"【Satoru】-kun, I'm also……♥ I'm cumming too♥♥"

　Keeping the image of what had once been his own face—now completely melted with ecstasy—burned into his memory, Kozo ejaculated powerfully, over and over again.

(End)
