Hey there, my name is Sam and I'm going to tell you about the best thing that's happened to me. What you need to know is that my uncle owned a chemical plant but what people didn't know was that he had a secret lab underneath it. That lab is the reason why my life would be forever changed. This is how it all started. One day I came to the chemical plant to pick some things up for me to take to my school tomorrow. You see my chem teacher wanted us to do this small group project and test out what we have been learning in class. It was cool until my teacher gave me my crush and once old friend Tanner Smith as my lab partner for the project. At one point in time we used to be really close and did everything together but once he got on the soccer and football team in 10 grade he changed. He stopped hanging out with me and soon he just stopped talking to me all together. I really didn't want to do all the work for this project, but I knew I was going to since my uncle would be able to help us but really just me by letting us(me) use a space in his chemical plant and the fact that me and tanner have done nothing together since he decided that being popular was more important than me his best friend. Tanner walked over to me and said “so are we doing this or can we just get your uncle to do it for us. I really need a good grade for this project so we should probably just let him do it and plus with me going to the gym and football practice and fucking my girlfriend I don't have enough time to help”. “Really dude I said, look you can't expect me to just use my uncle to do our work for us and you do nothing” ( i mean he's not wrong i get him to do almost all the work for my chemistry class all the time but that's not the point).”look Sam we both know you were going to do that anyways but look when he's done just pick it up and bring it to my house before school that way you can go over everything with me ok sounds good”. “Ugg yeah sounds good” but I mean what was I supposed to say? I can't make him do anything. I never could; he always did everything he wanted anyways with or without me. A few days later and now we get to the day the project was due, I walked up to the chemical plant doors and used my keycard (yes I have a key card my uncle trusts me with anything) once I was inside I walked over to the area that had my lab project. But there was a problem. There were a lot of other test tubes near the side and I didn't know if they should be there or not(yeah ik what you're thinking what did you expect to happen when you do a school project in a chemical plant but you know what no one asked you). (as might have guessed) These other test tubes came from the underground lab where they had a new chemical that my uncle was working on for the U.S government. You see he had a contract with them to help C.I.A spies go deeper undercover and not be found out that they were American spies. After looking around I found a note from my uncle “Hey kiddo you left these out last night but I know that you had to get home a little early but you need to make sure everything is up before you go so I went ahead and took care of it but if you were working here I would have to fire you now don't make me fire my own nephew anyways ‘don't spill these on your clothes ok’ be safe and love you.” -Uncle Kevin. I smiled and packed everything up. The only thing that bothered me now was why did my uncle have ‘don't spill these on your clothes’ written so weird eh I'm sure he was just trying to mess with me or something for not putting everything up last night. I looked at the time and it was 7:30, good I still have time to get to tanners. Once I got to tanners I brought everything inside and waited for him to come down I Looked at my phone and saw that he sent me something “Hey I'm almost back at the house from my run but you can go ahead and get you something to eat if you haven't already done so I have to take a shower once I'm back and after that we can do the project.” of course he was still out running and here I thought he was just up stairs jacking off instead of helping me. I texted back “ok thanks for letting me know” and a couple seconds tanner comes running in “wow that's a lot of stuff hope you didn't have a problem bring it inside but hey I'm going to take a shower so feel free to do whatever” and at that he left for his room. Now being the perv I am, I wanted to see if I could see him naked so I walked down to his room and saw that he had left everything open. I peeked inside and saw him take off his tank top and feel his sweaty abs and take his running shorts off. “Fuck” I said he so hot and damn that is a massive bulge. He then took out his phone and took a pic of himself
He then took off his underwear and his massive cock sprang free. He gave it a couple strokes and did some hot possess in the mirror and then went into his bathroom and turned on the shower. I took this opportunity to go in and smell his underwear. I went inside and picked them up and they were soaked from his morning run. I put them up to my nose and breathed in his musk and at this point my cock was so hard that I had to take it out. Once my cock was out I started to stroke my cock to what I saw just a couple seconds ago. It didn't take me long to cum but I knew that I would have never have this opportunity again so I went back to the living room and put his underwear under some pillows on the couch. After a while he came out and we got everything ready. While we were doing so tanner asked what the 2 new test tubes were and I told him that they must have been the control test tubes that I used. Tanner opened the lid and poured too much and ended up spilling some of the chemical over himself and getting some on me. I told tanner that he needs to be more careful and that he was lucky that it was the control group or we could have been in some trouble he said “yeah yeah sorry, fuck this was a good shirt it better not be ruined” and left to go put a clean shirt on. Not knowing that I had some of the chemical on me I rushed and put his underwear in my backpack. Once we got everything cleaned up we left for school. But on my way to school my body felt so hot even when I turned my AC to the max I was still sweating and hot, and at some points I thought I saw my skin move! But once I was at school I went to the chem lab and set everything up before I felt too sick and had to go to the lab bathroom. I walked in here and was so thankful that the lab bathroom was smaller than the others and that no people were in this part of the building yet. I went to the nearest toilet thinking I was going to throw up but the feeling left as fast as it came. After some time I took out tanner’s underwear and smelled them again. They were still wet so I decided that I wanted to wear them and took my clothes off(I mean I might as well right, oh come on tell me you wouldn't do the same) and put them on. Tanners sweat soaked underwear stuck to my cock and balls and it felt so nice but then that burning feeling came back and that when I noticed that my body was changing! “WHAT THE FUCK” I said as I watched as my back and legs started to grow and I began growing taller. I felt my decent 5 and half inch cock grow and stretch to at least 9 and half maybe more and how my balls grew to the size of two grapefruits. Oh God and feeling how and seeing it stretch the orange underwear out to compensate for my new size was just amazing. I then saw how my stomach became more defined as I started to get abs I've never had from years of going to the gym and hard core training. My arms then grew to match the new bulk of my body and I saw my face change and then it hit me. I was looking more and more like tanner! Once it was all done I looked at the full reflection of tanner and I took out my phone and took a pic of my new body
Holy fuck am hot. I just couldn't help but to take more pics of me showing off I just couldn't I mean how could I?
I mean just look at me. With every new pose and every new pic I took I felt my cock grow even harder and hader and I felt more like him in some way. I decided that one more pic was good and I'd leave to figure out what was going on. I went into my contacts and found my boyfriend’s name and sent him a pic of me flexing and a text
”Hey babe tonight is going to be an amazing night, meet me in the parking lot in 5min”. And then I put my shirt on and left the chem lab. I waited by my car with my phone to pass the time, and then saw my boyfriend walking over “Hey!... Tanner dude why the fuck do you have my boyfriends phone.” “Oh dude, chill, it's me, it's Sam” I said to him “ah ah very funny now yet again why do you have his phone”. “ look don't believe me here i'll prove it in 10th grade after i got cut from the soccer team you came up to me and said that i was better than every single one of them and that i was by far the cutest one out there.” “dude no way how the fuck do you look like tanner”. “I don't know but I think I have a clue. You see my uncle must have given me the wrong test tubes because oh wait that's why he had the words the way they were he was telling me what to do.” Uh? My boyfriend said look. After we read the note we realized that there might be a secret code my boyfriend took out his light and put it under the paper and when he did words started to appear “ My dear nephew I know that life is hard for you and if you're reading this it means that you have transformed into someone my guess is that you've turned into tanner but look Sam the chemicals that I gave you allow you to change into anyone as long as you have something of theirs or have made contact with their skin with the chemical on you. With this being said you can be anyone and do anything that person can do so Sam go out and have fun with your boyfriend or hell get with tanner or even ruin his life i don't care all I want is for you to enjoy life and not be down in the dumps like you've been for weeks with love -Uncle Kevin. ”dude that awesome you have the best uncle ever.” so about tonight why don't we make that right now I said to my boyfriend as I started to kiss him. We got in the car and drove back to my house and once we got inside my room, I shoved my boyfriend Jason against the door roughly from the inside, while I'm at his front, pushing my lips against his. "Oh Sam...mmmm...that..." Jason said under the kiss, but I made him shut up with letting my hand glide down Jason's front towards his pants. Jason moaned when I began to open his pants and my hand slid inside. "Two can play that game..." He murmured and let go of my arm while I still held him against the door, instead letting his hands travel down to my pants and opening them, letting his hands go inside while his tongue started a wild tongue play, determined to find out who was stronger, better, and more dominant. Sadly, we seemed to be pretty well matched, for neither of us would back down, even when we both closed our hands around each other's dicks and started pumping. Then he tore himself free of my one arm that was holding him and he pushed me against the wall next to the door, pulling his shirt up and his pants down. I had a new body so I would not allow him to win so easily anymore so I fought against him again but Jason's grip on me was tight and his hand on my dick was merciless. "You...will not...make me..."I said through clenched teeth and sweat ran down my forehead as I still tried to tear myself off the wall. Jason chuckled and began to lick and suck down my neck, biting down at a spot between the neck and shoulder. I couldn't suppress a little gasp as the sensation was so good. Then his grip on my erection hardened and he pressed down hard on the tip, making me shiver with pleasure. The two of us looked into each other's eyes, determined to not give in to the other one. But I would win so I used my new body's strength and pushed him up against the wall with one arm across his chest, using my whole weight against him, while his other hand was still in my pants, jerking me off and trying different movements to get a submissive moan out of me. He stood his ground, even though he couldn't get away from the wall and he had my dick still in a firm grasp, concentrating on the tip of it, which felt annoyingly good in this new body. He pushed our bodies harder together, so we could feel each other's hot skin pressing against one another. Then Jason let go of me and ripped his orange t-shirt off his body and attacked me with full force. I couldn't even look around fast enough, then I was back against the wall again, both hands suddenly above my head, Jason's mouth on mine and one of his annoyingly good feeling hands moved over my naked upper body. As he neared my nipples, I started to moan thrust into his touch as His fingers started pinching and playing with my nipples. I then had to show him that with this new body came a new top so I managed to rip himself free and tackled Jason, pulling his shirt up and kicking his own pants down completely, as we both fell onto my bed, Jason beneath me, staring up at my new face. I pushed Jason's t-shirt up so Jason couldn't see for a moment, then pulled his pants down to expose his dick completely. For a moment, he stayed like that, just staring. "Damn babe! We are even the same size!" I said and Jason, finally managing to get his t-shirt off his face and his hands free again, and look down at our erections as well. Then we were all over each other again, I on top but unable to do much with that, other than rub our dicks together, as well as the rest of their bodies and kissing and gnawing at each other. Then I felt Jason's hand on my backside and growled, his eyes narrowed to mere slits. "No. You. Won't I said." Jason then grinned up at me maliciously and said "But you'd already be used to it, wouldn't you even in your new body?" I hissed and tried to get the upper hand again – which I did, surprising my boyfriend, as I suddenly held Jason's arms over his head and had his other hand travel down his well-trained body. "I'm going to make you scream my name, Jason." I said and pushed My finger into Jason, who flinched and moaned. Finally Jason had submitted to my new body's strength. So instead of throwing me off him or stopping me in any way, Jason's hands travelled all over my body and while one of his hands began to pump my hot, pulsating dick again, the other one stayed with my nipples and I let a loud moan escape. I then added a second finger to the one already penetrating Jason's butt. I started fingering him until I knew I had found what I was looking for when Jason suddenly groaned through clenched teeth, his eyes tightly shut. I practically gloated and continued hitting the same spot over and over again as I added another finger. Jason's hand that had been on my nipples wandered down to my balls, where it began to massage them while his other hand concentrated solely on the tip of my cock now. Now it was my turn to hisse as pre-cum trickled out of my cock. I knew what I needed to do for the first time I was going to be the top and fuck my boyfriend so Instead, I pulled my dick out of Jason's grip and positioned myself between Jason's legs and pulling out my fingers, and replacing them with my cock. As I pushed into Jason for the first time, I could only see stars. Damn babe you're so goddamn tight and good around this dick I moaned! As I started to get a better feel and potion I started to push myself deeper and deeper into my boyfriend, letting the tightness around my dick take my breath away. I then grabbed Jason's dick and tried to time my thrusts with the movements of my hand, intently watching Jason's face for a sign that the pain was at least subsiding. "So you ARE enjoying it?" I said as I grinned and leaned back to change the angle of penetration, aiming for the spot I had hit with my fingers earlier. Jason kept moaning with each trust and crying out my name. It was the best feeling I have ever had. At this point we both could feel how close we were to orgasm. The way Tanner's body handled his dick was simply too good. So, desperate to at least not be the one to cum first, Jason grabbed my nipple with one hand and started rolling it between his fingertips, squeezing it. He had me gasp for breath and then curse “OH FUCCK”. "Not...fair..."I hissed and Jason could feel how close my body was when it began to tremble. A grin formed on his lips, though it was hard to really control his face muscles that well right now. Jason wanted to moan out loud and just let his orgasm take him, but he was so not going to let this end just yet. He closed his eyes and let his head fall back. Just letting the feeling of my dick in him take him. He then opened his eyes again and met my gaze, His face was a mixture of pain, pleasure and the urge to cum. The seagreen eyes bore into my own and for just a moment, Jason was distracted – and his orgasm took him by force. Jason ended up moaning out loud like a girl, and he still couldn't keep his body under check to not move so much. But right when he thought he had really lost, he could hear me cursing and groaning out. And for some reason, hearing tanners low, husky voice intensified Jason's orgasm even more. While I groaned and cursed as I stared down at my annoyingly good-looking boyfriend beneath me, a writhing moaning wreck – which was exactly what made me cum so hard in the first place. After it was over I started pushing into Jason, filling him with my new sperm as wave after wave of pleasure and ecstasy hit me and made me see stars. Then my new arms gave way and I dropped onto Jason, vaguely feeling how something wet smeared along my chest as I tried to slide off Jason. Lying next to him more or less, as we still painted and tried to catch our breath. Then my phone buzzed and it was a text from my boyfriend looked at the person next to me and back at my phone and opened it
Damn I'm sorry I just saw your text. I hope it wasn't important but yeah I can’t wait babe but why is tanner sending me shirtless pics with your phone? everything ok?
I looked at my text in shock and looked at who I thought was my boyfriend “Damn jiggs up isn't it ”he said. “who the fuck are you I screamed at him”. “Oh you know who”. “Wait tanner”? “Yep right on the money big boy.” but how and why i said. Well you didn't know that I came in and I saw you go into the lab bathroom. I wanted to make sure you were ok because you didn't look good and I wasn't going to do that presentation shit by myself. But then I saw you transform into me. I then put 2 and 2 together and went up to your boyfriend with the chemical and a few seconds later I became him and walked outside that's when i saw you. “ wait then why didn't you confront me or more importantly why did you change into my boyfriend.” “because I wanted to know what it would be like to fuck myself but no in all honesty I want to see what it would be like to be with you i made a horrible mistake letting you go.” “But wait what about your girlfriend”? Oh her well yeah she's bi too so we just cover for each other.” What then if you liked me then why were you being such a dick to me. I don't know man I'm sorry but hey I let you see me naked and take my underwear yeah I knew that you were watching me I did it on purpose I know that your only with Jason because you couldn't be with me tell me I'm wrong and we can just go back to how things were tell me that you don't want me or don't want me to be Jason because I know I'm right and so do you. I...I... see you cant even say anything so how about you just say yes ok. Do you want me because I want you. Yes oh God yes.
And from that day on I've been with tanner or should I say Jason ever since.
