The soul box

──Ding-dong.

"This is Sagara Express. I have a delivery for Eizo Ono!"　

(It finally arrived……)

　I opened the front door, suppressing the urge to jump for joy at the arrival of the long-awaited item.

"Oh, hello. You must be Eizo Ono, right? Can I ask you to sign please? ……Thank you! Also, I need to confirm that the item is correct……"

　The man's brown tanned, stern face relaxes and smiles. He has a fresh smile and is tall, muscular, and strong. His upper body muscles and legs are strong and sturdy, giving him the appearance of a professional fighter rather than a delivery man. The polo shirt uniform of a well-known delivery company is very sexy on such a sportsman-like man.

　After I had finished inspecting his body, receiving the package, I turned my gaze back to his face. He had a thick neck like a boar and a square face with a stout chin. Short black hair that looked hard as wire. His expressionless face could be intimidating, but thanks to his affable smile, the impression is quite different.

　Frankly speaking, he is very erotic. A big guy wearing glasses is sexy, as is the mustache that connects his sideburns. His strong face makes him look a little older, but judging from the condition of his skin and the tension of his muscles, he must be in his mid-twenties.

"I'll cut the duct tape. Could you hold the package for me?"

　I tried to remain calm as I watched him use a cutter to cut through the duct tape attached to the package. The armpits of his polo shirt were darkened with sweat stains, and his cleavage and forehead were streaked with sweat. The close proximity of the young man's body made the indescribable smell, which could not be masked by antiperspirant, irritate my nostrils to the point of overpowering. The tip of my cock, tucked between my legs so that no one would notice my erection, would probably be overflowing with pre-cum.

"Here you are!"

　His doggy-like smile urged me to take out the contents of the package. Inside was a box the size of a lunch box made of ebony. True or false, if I opened this box, my wish might come true. I tried to remain calm so as not to be noticed by my racing heartbeat, and slowly opened the lid of the box.

"What? There's nothing in the box……"

　The deliveryman was right, there was nothing in the box. However, when the lid was opened, a cloud of pure white smoke gushed out from the bottom of the box, and it was sucked into both of our noses. An aromatic scent pierced our nostrils. It reminded me of dense male pheromones.

──What a sweet, alluring smell……

　We were so intoxicated by the smoke, which emitted a fragrance that was both intense and intoxicating, that we unconsciously embraced each other, our cocks erect, and exchanged the 'something' that was overflowing from our mouths through our lips.

＊＊＊

"Ummm……"

　My body feels tired. I don't want to open my eyes. My head felt heavy, as if I had a hangover. In my blurred consciousness, I put strength into my eyelids, which were resisting me, and loosely opened my eyes. The ground was cool to the touch. The sensation told me that what I wanted had come true.

"Yes, I did it! I have succeeded!!"

　I felt my brain tremble as the deep voice that escaped my mouth reached my ears. I stared at my hands below me, then touched them all over my body. I looked at my large hands wearing blue work gloves, and my arms, thick and veiny, reminding me of logs. When I moved my gaze to my crotch, I had a boner in my shorts tight against my skin, and even without touching them, I could see that the cock hidden inside was of an extraordinary size.

(Hahaha! Awesome! That's fucking awesome!!)

　Suppressing my excitement, I quietly went crazy on the spot. My dream had come true. The person who fell prey to the 【Body swap】 was Ryoma Uchida, the delivery man who has been in charge of my house for the past couple of years. Ryoma's body was as close to my ideal as possible. He has a magnificent face and a muscular physique with abundant muscles. When I looked at my own body in the mirror in the shoebox at the entrance, I felt again that we had successfully swapped bodies.

　The pleasure of being able to freely run my fingers over the rugged, macho body that I had always wanted to touch. My cock was painfully erect and never lost its strength.

(The pheromones overflowing from this strong male body, the sensation when my cock is getting erect…… is irresistible♥♥)

　I can feel the dopamine pumping through my brain. My underwear is probably soaked in my own pre-cum. I want to get naked right now and use 【myself right now】 as a jerk-off material to masturbate. But I can't get carried away. Ryoma, whose body has been swapped with mine, will wake up.

"Ummm……"

　Ryoma, who had just moaned, got up.

"Hey, you…… Are you all right?"

　I gave him a somber, puzzled look and spoke to Ryoma in a thin voice. In front of me is a man who looks like the man I was a moment ago, from the top of his head to the tips of his toes. Such a sight made my cock, which had been trying not to get an erection, tingle again. I held back my cheeks from loosening involuntarily, and somehow managed to keep my mouth closed.

"Uh……? What was I doing……?"

　His head still seemed to be in a daze. I held Ryoma, who was looking around, up with my thick arms and said in rapid succession.

"This is my house. Don't be surprised if you see…… We seem to have swapped bodies."

"Eh? Wow!! Oh, I'm right in front of me……?!"

　After fumbling with my face and body with both hands, he stroked his own smooth bald head with his plump hands and looked aghast. He finally seemed to realize the situation he was in. The two of us had swapped bodies, and this was an unusual situation.

"What do you mean, our bodies have swapped?! Why……!?

What the hell is going on?!!"

"I don't know either. When I woke up, we were in this situation……"

　I don't know what's going on. After taking such an attitude, I made a deliberate expression of realization and picked up the box that caused the problem.

"It's this one! It might be because of this box! Actually, I have a hobby of collecting odd antiques…… This box is called the 【Soul box】, and it is said to be an item that was used in medieval Europe for 'the ritual of swapping human bodies'. It was written that 【Body swap】 would never happen except under certain conditions, so I opened the lid of the box easily…… My apologies! It's my fault!!"

　Ryoma, who did not understand my desperate explanation, kept his mouth open. I clutched at his feet with a few tears in my eyes and rubbed my forehead against the floor.

"I'm sorry for the trouble I've caused you……"

　I rolled my back and acted like I was crying, and when I looked up after a few moments, Ryoma with 【my】 face looked as if he had lost his venom. It seems that pulling at his heartstrings was a success.

"Please raise your face…… I was surprised, but it wasn't your fault, Ono-san. You only opened the box because I told you to check the contents, right?"

　Ryoma is concerned about me. I feel guilty, but at the same time I almost laugh myself silly. What an innocent young man. Wiping my tear- and snot-stained face with my burly hands, I smile at him and show him a smile.

"……Thank you, Ryoma! You're so kind…… Oh, by the way! How's your work going? Don't you have another delivery to make after this?"

"Oh, that's……"

　Ryoma's face pales and he looks anxious. Hehehe…… I'm sorry, but I'll take advantage of his weakness. Curry favors him and gets to know him better.

"Well……, if you still have some packages left to carry, let me carry them for you, won't you? Let me atone for you!"

"No, I can't…… ask you to do that for me.……"

　To Ryoma, who was silent, I pressed for an answer.

"Please let me apologize! After I'm done, you can do whatever you want with me!!"

　Tackling him, I hugged his waist and rubbed my cheek against his fat, flabby belly. Perhaps losing patience with my desperate appeal, Ryoma opened his mouth.

"……Hah~, I understand. Then, can I ask you for a favor? I can't go back to work in this form anyway, and I'll navigate in the passenger seat, please, for the delivery."

＊

"It went well, Ryoma!"

"Mmmm…… Hey, hey, Eizo! What are you doing?!"

"Oh, I'm sorry!"

　The two of us arrived back at my home, but I couldn't hold back and sucked on Ryoma's lips. Ryoma showed signs of reluctance at the sudden turn of events, but his face looked a little happy.

"I…… have never kissed a guy before……"

"Me too……"

　I felt a strange sensation between my legs and looked down to see that Ryoma's pants were also bulging like mine. It seemed that the tip of his cock was dripping pre-cum and even stained.

"What are we going to do now? Do you think they would believe me if I reported it to work?"

　Ryoma asked me to talk, trying to hide his excitement. I made a mysterious face to match his and answered in a low voice.

"Well…… I think it is safe to keep it a secret. I wonder if anyone would believe you if you told them that our bodies had been swapped. I can only see a future where people will think you've lost your mind and fire you immediately……"

"They're going to fire me…… Well, that's right…… Hah~……"

　As expected. I suggested to Ryoma, who hung his head in disappointment again, that I would give him a helping hand.

"In the meantime, as unwilling as it may be for you, I think we should keep our acquaintances in the dark about 【Body swap】 and pretend to be each other while we gradually find a way to get things back to normal. Oh, yes……!"

　As I ran to the back of the room with a slam, I returned to Ryoma with two clear cylinders in my hands, connected by a tube.

"Would you like to try this? This is another one of those mysterious antiques called 【Memory sharing device】, and if we put each other's male genitals in these cylinders, we can share our memories through the tube. If I can get your memories, I can do the delivery work instead of you, and people at your workplace won't even notice that we've swapped!"

"Male genitals you mean cocks, right?! I'm kind of worried about it…… But if it allows us to pretend to be each other, then we have to use it. It's my fault too that we switched."

　After receiving the clear cylinder, Ryoma let out a deep sigh of resignation, took off his pants and underwear, and placed them on his cock. I felt a thrill go up my back as I watched him puzzled by 【Eizo Ono】's body, which was full of fat and also had a short uncircumcised cock.

　I, who had been watching him as if in a state of gazing adoringly until he finished attaching the device, also took off my underwear and attached the cylinder to cover my own cock. Then, facing each other, we turned on the 【Memory sharing device】 switch. A vacuum sound echoed in the room, and the cylinders tightly adhered to our crotch, and the two cocks that were stimulated within them enlarged rapidly. We turned our cocks heavenward as we bridged, and with our whole body convulsing, we released a large amount of semen into the cylinders.

"Ahhhh! Whoa!!"

"Ooh!? Aghh!"

　I've never had a blowjob before, but perhaps this fulfillment is more than that. The stimulation of my cock inside the cylinder stimulates my ejaculation, and I feel the spewed semen being sucked into the tube rapidly. The sensation was more intense than anything I had ever felt before, and I repeatedly screamed out, my white eyes rolling back. Ryoma seemed to be doing the same thing, his Ahegao exposed and writhing in agony.

　Inside my scrotum, my two testicles kept busy, and I could not stop ejaculating. We kept our backs turned and our whole bodies kept shaking. Finally, after squeezing out every last drop, we collapsed to the floor at the same time.

"Hah……♥ Hah……♥ That was amazing……♥"

　I muttered to myself, drool dripping from the corners of my mouth, and Ryoma replied, his whole body also drenched in sweat.

"Wow, that's great…… Huh?! Aww♥♥"

　The show of the 【Memory sharing device】, which seemed to have ended, comes to finish. The cum unleashed from our cocks goes up and down the tube and into each other's glanses. There are no words to describe the pleasure of having our testicles fucked as the semen flows back up our urethra. Sparks fly in my vision, and I struggle to escape this pleasure by moving my fingers and toes, but it is futile. The whirlpool of pleasure, from which there is no escape, erodes my rationality, and my brain melts into mush.

"Aheeeee♥♥"

"Ohohooooo♥♥"

　We embraced each other, roaring like beasts. Our foreheads and noses rubbed against each other, our tongues entwined as we explored the position of our lips. My vision flickered with the pleasure echoing from both mouth and cock. I feel Ryoma's cum become fine particles, assimilating into my blood and flesh as he caresses each and every blood vessel spread inside me. My soul becomes accustomed to the male body of 【Ryoma Uchida】. Ryoma must also be in the same situation. His eyes are glazed over and his ugly mouth is loosened like that of a dog in heat.

　We continued to roll our eyes back, snot dripping out our nose, and show our ugly Ahegao. Finally, when the cylinders were empty of semen, our consciousness was cut off.

＊

"Achoo!"

　I felt a chill and woke up with a loud sneeze. I frowned at the uncomfortable feeling between my legs. My cock was exposed and the clear cylinder was sucking on the base of my crotch, which was a very stupid look. When I lifted my upper body, I saw a man lying on his back, just like I had been before.

"Hey, are you all right?!"

　I ran up to the man and shook his shoulder. He slowly opened his eyes and looked around. When his eyes met mine, he opened his mouth, his eyes wide.

"Ryoma……?"

　He muttered this reflexively, but immediately wrinkled his brow and groaned.

"No, no……, 【Ryoma Uchida】 is…… me!"

　Thanks to his words, which distorted my face in pain as I held my head in my hands, I also remembered that I was 【Eizo Ono】. The effect of the 【Memory sharing device】 was so great that if he had not said no, I would have forgotten for the time being that our bodies had been swapped. I had planned to obtain 【Ryoma Uchida】's memories and become him exactly as he was, but once I forgot that I was 【Eizo Ono】, it would mean nothing even if I obtained everything about him. If I did not retain the memories of my former self, there would be no point in swapping bodies.

"That's right. And I'm 【Eizo Ono】……"

　After a few moments of awkward silence, he opened his mouth.

"For now, I will leave 【my】 job as delivery man to you. After the work is done, we will be back here to discuss how we can get each other's bodies back together again. In order to avoid causing trouble in the workplace when the 【Body swap】 is discovered, and to get back to normal without people knowing about it……"

"Okay…… Roger……"

　He looks too serious and I feel guilty. Is it because I got the memory of 【Ryoma Uchida】? But he must have understood my feelings, because he said to me in a stout voice

"I'm sure our bodies will return to normal, so don't worry about it."

＊

──Pow, pow, pow……!

　It's been a week since our bodies were swapped. Although I felt bad for the pure Ryoma, I whispered in his ear what I had always wanted to do with my body-swapped partner.

──If we masturbate together with a special double-headed dildo in each other's asshole, we might be able to get back to our original bodies.

──If we suck each other's cocks in a sixty-nine position, we might be able to get back to our original bodies.

──If you do anal masturbation while swallowing the cum that came out of your own former cock, we might be able to get back to our original bodies.

　Even though the suggestions were obviously dubious, he had to be convinced that he had to get back into his old body.

　I shoved my cock into his mouth while I held his head in place with my hands and swung my hips, causing him to cum deep in his throat. With a dildo in his asshole, he ejaculated while sucking his former cock. He took my very silly rule that I thought up and did everything exactly like that, spreading his cum all around.

"Phew~……♥"

　I looked down at Ryoma, soaking in the post-ejaculation fatigue. His mouth, half open from sucking cock, was dripping cum, and the dildo was slipping out of his flaccid anus, causing Ryoma to let out a low, muffled moan. My heart was pounding at the sight of that hapless, pathetic figure. He was too good to me. I felt so guilty for treating this strong but gorgeous body as if it were my own, and changing it to my liking.

"Um, we might be able to get back to normal soon……"

　At those words, he wiped the cum from his mouth with his sleeve and asked, 'Really?' He threw the question back at me. His face, which I was sure he would be pleased with, was somewhat clouded, and he was staring at me with suspicion, as if he was paranoid about me. It was natural for him to be suspicious. He had been discouraged after accepting my smelly proposal so many times. If I were in his shoes, I would have the same reaction.

　However, his kindness in not blaming me for the situation stimulated my sadistic side, which I did not have before the 【Body swap】. I want to thoroughly trample on his humanity and his trust in me. Such feelings fill my head, and unconsciously I feel the corners of my mouth hanging open. I want to take away everything he has at the moment he is relieved that our bodies will be returned to normal──.

"Hey……, are you okay?"

　His quizzical voice brought me back to myself. Watch out, watch out. Was I drooling? Wiping my mouth, I hurriedly made up for it and said to him.

"Sorry, I was just thinking! It's true that…… we can return to our bodies, but there's a little problem with……!"

"Problem? What's that……?"

　I answered Ryoma with a dubious look on his face as he asked me that, while I was slurring my words.

"……Well, in other words. In order to return to our original bodies, we need to breathe the smoke from that box again while having sex……"

"Oh, yeah. That's not a problem. We have sex, hmmm, sex! ……Huh?! Sex?!"

　We have had a lot of sex-like activities in the past, so what is the need to panic now? However, as a straight man, male-on-male sex must be unfamiliar territory for him. I spoke to him in a gentle tone of voice, trying not to arouse his anxiety as much as possible.

"You don't have to be so scared. I'm just going to put my cock in and out of your ass. Right?"

"Well, well…… yeah? And now we're back to normal, right? So, is it worth a try……?"

(You're so quick to convince me……!)

　I was half stunned when he loosened his tense expression and murmured in a relieved tone, but feeling affectionate toward him, I pushed his body down. I had been wary that he might resist, but he kept his eyes and mouth tightly closed, tensing up in anticipation of the unknown that was about to happen.

　I asked him as I fingered his anus.

"Can I creampie you……?"

"Huh?!"

　He exclaimed and froze with his mouth gaping open. 【Eizo Ono】's asshole had been played with a dildo so much that he would have no problem inserting 【Ryoma Uchida】's cock, which has a huge cock. However, even though he is well-behaved, he seems to have some resistance to getting creampied. I was about to say, "If it's impossible, we'll have to find another way……," while showing a little hurt by his reaction. But he interrupted me and said in a strong tone.

"No! It's okay! Just put your cock inside me!!"

"What……?"

　I asked him fearfully, overwhelmed by his energy.

"Hey…… Are you sure?"

"Sure, of course! I'm ashamed to say it, but……, ever since I've had this body, I've wanted to be fucked…… My body is throbbing with the desire to be fucked by a strong man like you……!"

"E……, 【Eizo】!"

　I got the permission from him that I had been waiting for, and I vigorously hugged his thick body. He, too, puts his arms around my back and hugs me tightly. He was bald, a head shorter than me, and had a lot of flab on him, but how adorable he was!

"【Ryoma】……!"

　Our cheeks were flushed, and we moved our faces to each other's and put our lips on each other. It was a thick, sticky kiss. Our tongues entwined with each other and saliva was exchanged, making my head melt with pleasure. After kissing for a while, we parted our lips, letting our saliva flow.

"【Eizo】…… I can't take it anymore……!"

　I reached up to his buttocks and inserted a rugged finger into his loose anus and fumbled, and he too looked up and murmured as he stroked my cock.

"Me too…… 【Ryoma】! Hurry up and satisfy me with your big cock……♥♥♥"

　My cock is already soaked with pre-cum, and my balls are already puckered up with sperm. Ryoma, who has had his body swapped with the hideous looking 【Me】, has given in to his sexual desires and spreads his own asshole. Then the time finally came when I, who had taken over his straight and macho body, put my cock inside his asshole. My excitement was at its peak at this perverse situation.

"Well then……, I'm going to put my cock inside your asshole……"

"Yeah, I'm all set, 【Ryoma】! Hurry up and penetrate me with your cock!!"

　His words pushed me forward, and I thrust my hips forward and pushed my cock, which was resting lightly against his anus, into the hole. I pushed forward, and in the blink of an eye, my cock was sucked down to the root.

"Wow, it's amazing……♥♥♥"

　I hated my body. I've been short since I was a little kid, and even when I exercise, I'm fat and slow. The hair on my head is thinning and my skin releases the ageing odor. However, there was something good about 【my】 body. It is soft and warm, and when I insert my cock into it, it squeezes my cock as if to envelope it. It was the most beautiful thing about this body.

"Great♥ Your asshole feels soooo good……♥"

　I moved my hips violently, intoxicated with pleasure. The walls of flesh entwined with my cock. Each of the countless folds carefully licked up the sensitive part of my cock. We licked the tips of our tongues together and our lips overlapped as we enjoyed the pleasure.

"Mmmm……♥ Chupu……♥"

　In the body of such a short, fat, bald old man, the soul of 【Ryoma Uchida】 resides. And now I control such a body of his and use it as much as I want. I was thrilled by this situation that came about as a result of the body swap. My hips naturally move faster. He responded by entwining his flabby legs around my waist.

"【Eizo】……♥ I'm about to ejaculate……♥"

"Me too……! Let's cum together, and pour your sperm inside me as hard as you can♥♥"

　His flushed face and sweet words may have inspired me, but my cock is even harder and harder. It's the last spurt! I slammed my cock into his now slippery asshole with great force.

（Cumming! I'm gonna cum!!)

　Just as I was about to reach my climax, I opened the lid of the 【Soul box】 that I had kept nearby. Just like that day, the smoke from the bottom of the box was snuffed into our nostrils. The smoke that passed through our nostrils immediately reached our brains, and we writhed violently with pleasure. The feeling of floating, like when drunk, and an incomparable euphoria. My cock swelled up like it was about to burst, and I felt like I was going crazy.

""Uhehe♥♥ I'm cumming~~♥♥""

　With a pathetic voice, we spewed out semen as thick as jelly. With each ejaculation, I feel my soul becoming more and more familiar with this body. Using the 【Soul box】, the bodies of two people in close proximity can be swapped. However, the effect is temporary, and it takes exactly one week to return to normal. But if two people share the smoke in the box again within the period of time before their bodies return to normal, they will remain swapped.

(Hahahahaha, I will take your body, your life, your everything, Ryoma!!)

　From now on, I will live as 【Ryoma Uchida】, using this stern face and muscular, erotic, and sexy body──.

＊＊＊

"We are both back in our original bodies, Eizo!"

　Ryoma, seeing his reflection in the mirror on the wall, stroked his face and body with his thick palms as if to check them, and exclaimed with relief and joy.

"Yeah, it's really good to be back. I'm sorry. I've been using your body as I please for the past few days……"

　Eizo, who was standing next to Ryoma, muttered reluctantly as he looked at Ryoma's image in the mirror, and Ryoma bent his huge body and put his mouth close to Eizo's ear.

"It's okay. I was surprised at first, but it felt good to me too……♥"

　Eizo's apologetic expression almost made Ryoma spit out, but he managed to hold it in and smile so that it looked natural. The only person who remembers the event of the 【Body swap】 is Ryoma, who is now recognized as the owner of the 【Soul box】. Eizo, who is not the owner, believes he is 【Eizo Ono】 under the influence of the 【Soul box】. It's hilarious and exciting, isn't it?

"More than that, because you've used my body as you please, I've become awakened to homosexual sex, even though I was straight until a week ago. As a matter of course, Eizo, you'll take responsibility, won't you?"

"Oh yeah! Of course! I'll do anything you say!!"

　He replied as he shouted and clutched at Ryoma's legs. Ryoma, holding back his laughter at Eizo's ungainly appearance, continued.

"Well then, I'll have you lick my cock clean♥"

　Ryoma whispered as he stomped on Eizo's forehead. The cheeks are bright red and Eizo's face looks like a pig. Ryoma looked down at such a short, fat, ugly, pathetic man, and his erect cock dripped a lot of clear juice.

(End)
