m/m/f Elongro - Added Part 14 on 27-APRIL-2019

Recommended Posts


This story is a conversion of an old RP I did with a friend, @jsmith230.  It was one of my favorite RPs so I thought I would convert it and share.  While  my first preference is muscle growth with a secondary love of height growth, you could say his preferences are the inverse of mine.   So that will give you a hint of what this story will entail.

“Dude, have you heard of that new 'Elongro' drug? I have to get my hands on it. I want to get huge this year!”


Seth rolls his eyes as he listens to Trevor ramble on about the new miracle drug that has been making a splash among the young adult community worldwide.


Trevor and Seth are college roommates and best buddies currently in their second year of college. The two were paired up as dormmates during Freshman year and their friendship blossomed from there. Both 19 years old, the two share a small apartment just off campus. To the outsider, Trevor is the alpha of the friendship, much more confident, outgoing and outspoken than his counterpart. He has always been very athletic and since coming to college has fully invested his free time into fitness and working out. He's obsessed with trying to put on mass and is always trying the latest supplements, pills and powders, along with constantly reading articles on new exercises programs to try. He has built himself up to a nice, ripped, 185 lbs on a 5’10.5 frame. His body fat hovers around 10-12% and he sports a nice 6-pack. But, like any true wannabe bodybuilder, it wasn't, deep down he wanted more. Much more.


Seth is Trevor's roommate and while he also has a natural athleticism to him, he hasn't pursued it nearly to the degree that Trevor has, though few people could really say that. Some of the reason behind this is that Seth always felt just a bit too small to ever have great success in sports. He was one of those people who were content to be good enough to make the high school baseball team though he only saw limited playing time. Since college began, Seth exercised a couple times a week, mainly by just jogging, leaving him with a naturally slim and toned 145 lbs on his 5’8 body.


The pair were pursuing business degrees although Trevor wasn't quite sold on the idea after his first year. While Seth fully intends to pursue a sales and marketing career, Trevor has considered switching to a more body-centric physical therapy program that would work well in parallel with his pursuit of fitness excellence.


What currently has Trevor excited is the discovery of a new drug that offered an exciting possibility. Within the past year, a new compound was developed and released in Korea that is commonly known as “Elongro”. It's use had begun to spread across the developed world. However, due the USA’s overly strict drug testing protocol, the drug is still not legally available in the USA though it is available in most of Asia, Europe and Canada. The drug has caused excitement for people who are small in stature, either height or build. What the drug does is that it basically freezes a young adult growth rate, including hormonal levels, where that rate might be starting to wane. Along with enhancing the sex characteristics, it also keeps their growth plates open for an extended amount of time, allowing an individual to continue to grow for much longer than they normally would.


Seth shakes his head as he listens to his roommate explain the drug. “What that means, Seth, is that if you naturally had, say, one more month of growth before your plates fused, you might keep growing at the same rate for another 2-3 months instead with Elongro. But, just think, if you were in the middle of a big growth spurt and originally had many months, or year left, you could potential retain that growth rate for a few more years! Isn't that awesome!”


“Uh huh. Sure man. Sounds cool man,” Seth replied cooly. “Sounds a bit too good to be true, really.”


“Well, it's not perfect, you're right.” Trevor pulls up his phone to read the details of the drug from the website he'd been researching. “The major drawback of the drug is that it has been shown to cause devastating side effects if a person is still showing any signs of puberty. Most humans complete puberty by the time they are 16 or 17 but keep growing in size for another 1 to 4 years. Because of this risk, most countries that allow the sale of the drug ban it from being used on any person under the age of 19. Also, the drug will not work if a person’s growth plates have already fused, which for many people has already occurred by the time they are 19. Thus, the window for success for the drug is very limited, if open at all. The reports say that only about one-quarter of the people who try to drug experience any results.”


Trevor looks away from his phone at his disinterested roommate, but his own excitement cannot be interrupted and he keeps scrolling through the information showing on his phone.


“For those that it does work, though, the results have been significant! Bro, this website says there are online rumors from the drug’s testing phase of people putting on 40-50 lbs of muscle and growing up to 6 to 8 inches taller well into their 20s! Shit dude, that would ROCK! I read that for those who are lucky enough to still be growing, the average success rate has been 15 lbs and 2-3 inches over an additional 6 months to 1 year of growing. I would give anything to put on some more size like that! My training has really stalled lately.”


“That is pretty sweet, Trev. But you said it yourself, it may not even work. If you've finished your natural growth you're S.O.L.”


Trevor huffs as Seth downplays Elongro. Tervor can't help but imagine the possibilities. Though he never mentioned it, while focused on growing his muscles, he secretly always wanted to be taller as well. He hadn't told Seth, but he had already started the process of obtaining the Elongro. He had already set up a quick weekend trip to Canada where a close friend was to obtain a prescription and then supply him with a vial of Elongro. He's aware of the illegality but the chance to put on some size even if it's just a few pounds or an inch in height, is too much to pass up. Because of the drug’s scarcity and the fact he has to obtain it illegally, it will cost Trevor over $1200, a huge amount for a poor college kid.


“Seth, from my doctor’s appointment this summer I found out that I had grown another ½” to my current 5’10-1/2 height. So I'm positive I'm on my final growth spurt! I just KNOW it will work. But I got to get started soon before my growth stops.”


“Ok, man, whatever. Man, you really are obsessed with size. You've got that dysmorphia thing, haha. I men, you are already jacked, you should be happy.”


“Never big enough, bro!” the handsome stud chuckled in reply.


“So how does it work? Is it a pill or something?”


“Naw, it's an injection. It works from just one single injection. Each vial contain enough liquid for 5 injections, even though only one is needed. This is where you come in, bro!”


“Me? What for?”


“Well, the thing is, this shit is really expensive. And, like I said you only need one injection, but each vial has enough for five injections. So, I wanted to ask, If I get the Elongro, could I sell you an injection too? It would help me out and I would appreciate it. My girlfriend already said she'd take one of the injections too. Help a brother out, it's fuckin' expensive stuff. I'm not even asking for the full price of a dose, just $200 to help me cover.”


“C'mon Trev, don't ask me that. I don't... Man, I don’t think I’ve grown in a couple of years, it would most likely be a waste on me.”


“But, Bro, even if you had the slimmest chance to be just a little taller and stronger, wouldn’t you want to take it?”


Trevor tries his best to pitch the idea. Seth rebuffs his approaches but he knows what will get Seth on board.


“Hey, you know that girl that works at the rec center you’ve been crushing of the past year? Remember how you told me you overheard her talking with her friends that she said she would never date a guy under 5’10 and 175 lbs? She says that because she's pretty tall for a girl, like 5'9 or so. Just think, buddy! If you put some size maybe she’ll give you a second look!”


Trevor sees the gears turning in Seth's head. He still seems unconvinced but he can tell he's touched a nerve.


“C’mon man, you always told me how you felt like you were too small in high school to be one of the jocks on campus even though you were on the baseball team. This could be your chance to put on some size and least be average height. Wouldn’t you want that, little buddy?”


Trevor tosses in ‘little buddy’ because he knows Seth hates when bigger dudes call him that. And that seals the deal.


“Ugh. Fine, bro. Whatever," he says with annoyed defeat. "And hey, I’m way past puberty so there’s no risk, right? Other than I’ll be out $200."


“That’s the spirit, pal! I promise this will be worth the investment!”




Seth walks to his room to collect the cash. He can't help but shake his head at Trevor's crazy antics.


"This stuff is never going to work on me," he says to himself. But, knowing how into this Trevor is he knows that the right thing to do is to support his roomie and at least give it a try. Plus, that way when it doesn't work, he can hold that over his head! Or at least Trev will give it up and move onto something different, just like he always does.


The following weekend Trevor makes five hour drive up North to Canada. Upon his return he excitedly enters their apartment and makes himself known. That night, the two friends administer the shot. They both have it their our heads that the effect would be immediate, even though all of the documentation says they won't know right away whether or not it works. But the placebo effect is very real those first few days and it drives the two crazy not knowing for sure if they will see an impact, but the excitement builds.


That night Seth dream of growing taller, standing over guys who always made fun of his short height and pushing his skinny body around... being seen as tall... growing again... finally becoming the man he'd always wanted to be. Not being relegated to playing right field in baseball having never hit a home run. All those guys looking down at Seth! He jolts awake and realizes his dick is tenting the sheets. Even though he was skeptical at first, he can't help but think how deep down he must want this injection to work. How badly he needs to become bigger and stronger. He chuckles, knowing how slim the odds are and fades back to sleep.


After the first few days of no noticeable changes the two both act as if nothing has happened. Although they both seem to be constantly checking themselves against the heights of familiar landmarks and people, including each other. Inside Trevor is still stoked, convinced that he will reap significant gains. Knowing that Seth hasn't grown upwards in years, he knows it likely won't work for his friend, but he was happy he at least he got $200 out of Seth. Truthfully, Trevor loved having Seth as his roommate. Not only from a personality standpoint, but he loved being the bigger and more dominant man compared to Seth. It was nothing against Seth, it just fed well into Trevor's desire to get bigger and build up his physique. Whenever they went out, Seth always demurred to Trevor when choosing which movies to watch, with parties to go to, what girls to hang with. Trevor was the alpha apparent.


Two weeks after the injections the two are eating dinner and Trevor notices Seth is wolfing down a ton of food.


"Hungry, there Seth?"


"Dude," he says between mouthfuls of grilled chicken, "I can't remember the last time I was this hungry. I just can't get to feeling full lately... it's so weird..."


Trevor chuckles as he watches Seth go back to finishing his chicken before starting on some brats. Trevor shakes his head, teasing Seth that “the freshman 15 is real, just delayed for you" before getting up to do the dishes. A bit later the two are hanging out watching TV and chatting about classes and wanting to catch the new Spiderman movie. Seth rubs his full round belly and ponders, pausing, before finally asking his roomie a surprising question.


"Have you been making any gains in the gym? I was thinking rather than just running maybe I would try lifting some."


Trevor is taken off guard. He knew Seth never went to the rec center other than to run, and certainly never made his way into the weight room.


"I was thinking... maybe... I could like... join you sometime?"


While Seth has managed to stay relatively thin, having a fitness obsessed roommate might be starting to rub off on him a bit.


"Its just, with how I've been eating... maybe I should," he jokes. "I'll get fat if I keep eating like this. Plus, it wouldn't hurt to have a bit more muscle for the ladies... maybe get some attention for once. It seems to have worked out well for you!"



"Hell yeah buddy! I would love to be your training partner. Hell, I was thinking I might want to make a career out of it in the future, either personal training or physical therapy. I'd love to show you the ropes, you could be my first client! But, don't worry, little buddy, I won't charge you."


Seth's face tightens at the words 'little buddy' and Trevor instantly feels bad.


"Er...sorry, Seth. But yeah, even though you haven't been lifting I can tell you are a little bit thicker lately, just from all the food you've been eating. I'm still making gains, but it's slow going."


The next day Trevor takes Seth to the gym for his first weightlifting workout. Seth marvels at the poundages that Trevor buddy can lift. Trevor boasts that he can bench 225 lbs ten times and Seth seems to be in shock when he performs the feat. On his turn, Seth can barely do 135 lbs five times. He is disappointed but his new trainer props him up.


"Hey, dude, honestly that's a great weight, especially for your first workout. When I started I couldn't even bench 95 lbs once!"


Seth perks up at that. As the two leave the weight room Seth notices the hot girl at the towel desk, Stacy. He is understandably smitten as he steals glances.


“Fuck, Trevor. That Stacy is one super hot chick.”


"Oh I hear ya man. I certainly don't mind the eye candy when I come here to lift everyday. Would love to get into that...if I weren't currently dating Brooke, that is, haha."


Grinning stupidly, Seth replies. "Yeah, she's so hot Trev.... but I doubt she'd pay much attention to a guy like me."


Seth can't help but notice her height, not too far off from Trevor's. Noticeably taller than he is, certainly. That seems to be the case with a lot of girls on campus. So many of the college girls and guys seem so tall lately. Trevor laughs and reminds his friend that time in the gym won't hurt and that if he stays consistent and pushes himself that she won't care how tall he is.


"Muscles always seal the deal!"


Trevor chuckles and throws up a double bicep pose, flexing his impressive exposed arms, grinning cockily, causing Seth to roll his eyes.


"Trev, doubt you'll be saying that when you are a six footer with me looking WAY up at you!” Seth jokes. "Then you will be tall AND muscular. I'm going to look like a little kid next to you.... so yeah, I better start lifting more I guess!"




A few weeks go by and Seth has been sticking with the gym, much to the surprise of his roommate. While it wasn't like Trevor had no faith in his buddy, he just knew the dropout rates for new lifters was very high. Trevor continues to coach and direct Seth, both in the weight room and giving him advice on his diet . His training advice is sound, and both can already see an improvement in Seth's physique, though it's not been easy for the new gymrat.


"Ugh, Trevor, is it normal to ache all the time? I can never seem to really recover..."


“Haha, buddy that's part of the deal. Though the more you lift the less sore you should be. It could be that you're not taking enough time to recover. Could be that your muscles are actually growing or any number of reasons. Just growing pains. But, it means that you are actually working and growing, so be excited, man!”


Before long, Seth begins to notice that his shoes are uncomfortably tight. He'd worn size 9s since he finished growing taller a few years prior. At first he figures it's the workout. One day after class he hits the mall to get a new pair. While Trevor hangs out at their apartment he gets a text from Seth:


[Trev, you won't believe it. I had to get new shoes! Size 10.5!! Crazy!!]


Tervor's mind races, trying to process Seth's text. He'd been denying Seth's progress, playing it off as beginner gains. But could his smaller buddy actually be growing? A hint of fear and jealousy permeates his mind. He thinks to himself how his size 11 shoes haven't been feeling any tighter. He calms down and rationalizes that maybe the little guy is going to have one small growth spurt. There is still no way Seth will ever catch him. He convinces himself that must be growing too, even if his shoes still fit. I mean, your feet don't HAVE to get bigger to increase your height, right? Trevor remembers how he is up 7 lbs to 192 lbs, the biggest he's ever been and he doesn't seem any more muscular or more fat, so he assumes that extra weight is coming from added height. The thought calms his nerves and he smiles to himself, excited for the growth that lies ahead.




It is now six weeks after the shot and the two are once again in the gym working out. Seth has been make even more noteworthy progress and has settled into a dedicated routine. This time Trevor brings a notebook. In the locker room after the lifting session Trevor confronts his protege.


"Dude, I am a terrible trainer! I forgot to take your initial stats to see how you are coming along. So let's start now, better late than never. We'll use this notebook to make sure you keep progressing. It's good motivation too to see your lifts go up week after week. Ok, how tall again?”


"5 ft 8" Seth says, slightly annoyed. "Well, just a bit under actually."


“Really? Are you sure?”


Trevor looks at Seth, unconvinced. At first he is apprehensive to find out for sure, but he can't deny that Seth looks at least a little taller. Wanting to be a trainer though, he knows he needs to be accurate and thorough with his log books.


"Nah, dude, let's find out for sure."


Trevor directs Seth to stand against the wall while he takes a tape measure out of his bag. He measures his buddy.


"Just a hair under 5 ft 9, dude!"


Seth eyes widen and he looks at Trevor excitedly.


He shouts, "Maybe that stuff is working for me! I've never been over 5'8 before!”


“Dude, that's awesome! You're not quite AS tiny as before, haha. Ok c'mon let's take your weight.”


Next, Seth hops on the scale. It reads 160 lbs.


“Great job, Seth. That's a 15 lb gain in just 6 weeks. Those are pretty good beginner gains, dude!”


Seth can't be more excited as Trevor notes his huge grin. He is thrilled!


“Ok man, let's get your other measurements for the log.”


Trevor tapes all of Seth's a major muscles groups and writes them in the notebook.


Arms: 14.5”

Chest: 38.5”

Waist: 31”

Quads: 21.5”

Calves: 14”


Trevor can't help but mentally compare his own stats to feed his ego. While Seth may have crept up in height he took solace that he still had him beat everywhere. He knew his 17” guns, 42” pecs, 24.5” legs and 15.5” calves were all well bigger while his tight 30” waist was even more ripped than his little buddy's. Not to mention, from what he had seen of his roommate in the showers, he had more 'down there' as well, the thought of which gave him a reassuring grin.


“Not bad, dude! You've got some really big arms compared to the rest of you, definitely a strength. A good one to have too. Chicks dig big guns.”


"I still can't believe it, Dude. I grew! I grew!" he keeps saying, trying not to draw a ton of attention to himself. "This is awesome. If it's working for me, it MUST be working for you too! Do you want me to measure your height too?"


Tervor shifts a bit, clearly looking uncomfortable and conflicted.


"It'll only take a minute... come on... this is exciting!!"


Trevor shrugs and submits. Seth grabs and extends the tape measure, coming in closer to take his height. As he does, Trevor can't help but notice how much Seth seems to have closed that gap. The difference between 5ft8 and 5ft10.5 is noticeable, but an inch and a half really isn't. From a distance the two could look the same height! The thought causes the competitive trainer to shudder at the thought. He's always been bigger and taller than his roommate. "And it'll stay that way," he thinks to himself as he stands as straight as you can. The wait for Seth to declare the number feels like hours. Finally, he speaks.


"Five Ten, Trev. Still."


Seth pauses and watches for Trevor's reaction. He seems deflated momentarily before regaining composure. Seth attempts to reassure him.


"Maybe it works different on people depending on their growth stage... I'm sure your growth will come soon!!" Seth says, slapping his back, "Hell, you've made great gains in the gym so something is happening!"


Trevor seems to take this to heart, but Seth can tell he isn't completely convinced. Even so, while Seth is jubilant about his growth, he keeps it to myself to not offend his roommate.


"Hey Trev, how about you have Brooke come over? I can cook us dinner tonight. I'm starved!!" he says as they grab their bags and head for the door.


On the way back to their condo Trevor is obviously dejected but does his best to hide it. He can't believe that Seth is only about an inch shorter than him. And what happened to 5'10 and a HALF? Seth must've missed that last ½ inch, he tells himself. Still, it hurts not feeling as big. With the overall presence of his ripped muscles on his frame Trevor always felt like he towered over his smaller roommate. Not so much anymore.


That night Brooke comes over as Seth is whipping up a feast in the kitchen. Having listened to Trevor go on an on about how important a big diet is for big muscles, Seth knew a big nutritious meal would cheer his friend up, let alone sate his own growing hunger.


By now the two are well into the second semester of the school year. Everyone is deep into their studies neither had seen Brooke in about three weeks. When she comes in Trevor is stunned at how gorgeous she looks, even more beautiful than he remembered. He felt a stirring in his crotch as his girlfriend made her entrance. The FaceTime chats that they had been relegated to just didn't do her justice. She comes in wearing heels and is almost as tall as Seth! Trevor remembered her being about three inches shorter than Seth when he first introduced her. He now realizes she must be about 5'7 now! Seth too was stunned, noting how tall and sleek she looked. He recalled how Trevor told him he gave her the shot too and it seemed it was working on her too, maybe even more so than Seth!


"Hey boys!", she said as she entered.


“Hey babe! Damn, I've missed you. You are smokin'!”


She goes over to her boyfriend gave him a kiss. Seth notices that Trevor didn't have to bend over like he used to, or at all to kiss her on the lips. She looks over at her boyfriend's roomie.


"Hey Seth! You are looking good! I can tell you've been hitting the gym. Trevor said you'd been lifting with him lately. I can see that you've put on some muscle. You're going to have to move up size large, that medium shirt is looking a little tight! Trev, Babe, you must be a fantastic trainer!"


The trio have a great evening catching up with each other and enjoying the grilled Caribbean chicken dish that Seth prepared. That night, after the friends retire to their rooms, Trevor goes to town fucking Brooke. All night long he had been staring at his girl full of lust. She just looked so fit and healthy. She was always fit, but she seemed to be on a another level tonight. Maybe it was the longer legs. He also couldn't deny that he was in much need of some release due to the frustration that he seemingly wasn't growing nearly fast enough.




Over the next few weeks, Seth is like a demon in the gym, pushing himself harder and harder and harder. Trevor watches and celebrates his gains, proud that his training techniques are working so effectively. And yet jealously, he see's his buddy making gains so quickly. While Seth started out benching 135, he's now pushing 185 for the same number of reps easily. It's an astounding change. And his shirts keep getting tighter and tighter, to the point now that he's started borrowing old shirts from Trevor! Trevor shakes his head, barely believing that his supposed small roommate needed them now.


The duo keep pushing themselves in the gym, even during finals. They can hardly believe that the semester is almost over. It's even harder to believe that two are both getting summer jobs, though Trevor's will be out of state.


"Sucks I won't be able to train with you for a couple of months, Trev... it's really been awesome. I've never been so buff in my life."


Trevor has recently noticed that Seth's voice has gotten deeper over the last few weeks. Luckily, though, Seth hasn't seemed to have caught him in height. It's something they both have been watching for out of the corners of their eyes. During their last lift together for the school year Seth points to his notebook in Trevor's bag.


"Maybe we should take stats again so that I can keep track of the progress myself?"


“Erm...yeah man. Of course. Let's see how much mass you've put on, bro!” he says, purposely not mentioning height.


The two head to the locker room and strip to their skivvies. Trevor notes how's Seth's body has developed so much that he's not too far behind himself, a thought that worries him. Seth steps on the scale first. The two watch it, with widening eyes, as it swings to 175 pounds. Seth's face brightens excitedly.


"Dude... that's another 15 pounds in five weeks. NO WONDER none of my clothes fit!!! Oh wow I could tell I was getting some muscles when I look in the mirror, but this is awesome! Ok, let's take my other measurements. Bro, you are an awesome trainer!"


The two high five and Trevor grabs the tape and steps up to Trevor.


“Ok. Arms...16 and a quarter”. Woah dude. You are still rocking those huge guns, damn! And they are so defined, crazy, man.”


Seth flexes his arm and Trevor watches, stunned, as the ball of muscle leaps into relief. It isn't huge, but a big, solid, undeniable lump of muscle bulges. It is the first time he has seen his roommate flex in any way.


“Holy shit, Seth. Your peaks is sweet. Geezus. Ok, let's get the rest. Chest is...41”. Big gain of over two inches, wow. Waist is still 31”, so you're not getting fatter. It seems to be all muscle, dude! Legs...now 23”. Calves...another inch at 15. Those are some studly gains, dude! You're beginner gains won't quit!”


“Thanks Trevor, I owe a ton of it to you bro!”


“Any time, roomie! Ok move out the way so I can check my weight.”


“Hey Trev, can you take my height?”


“Erm...um yeah I suppose. You think you are still growing?”


“I think so. I hope so.”


It's the moment Trevor been dreading. Seth steps against the wall, standing as straight as he can. The anticipation is killing him. He WANTS to be bigger. HE WANT to be taller, even if it seems like he hasn't quite matched Trevor yet. Trevor measures him once... then again... and again.


"Dude, what's up?" Seth asks.


Trevor grins at him. Internally, Seth worries that he's hasn't grown anymore. Then shares the news.


"You are five-ten now!"


Now Seth understands the grin on Trevor's face. If he's 5ft10, that means...


"Dude! Trevor, you must have grown TOO!!"


The two high five, both ecstatic at each others' growth.


"I told you, Trevor! It was only a matter of time!!"


Trevor looks thrilled, FINALLY this drug was WORKING. Seth steps aside and readies his measurements without a word. It's clear he wants to know. He NEEDS to know.


Seth first takes his weight, "200 pounds! Swole man, damn!!"


And then he measures his height. "Almost 6ft, dude! You are nearly there!!!" *


Trevor is so excited he could almost cry. He bear hugs Seth and lifts him off the ground, taking note of how newly solid and heavy Seth now feels.


"Hell yeah buddy! We've both put on about an inch!” He sets his friend down. “But wait, you said 'almost 6 ft'. What was it really?”


"Oh,...um...it was right at 5ft11.5. Maybe just a hair under.”


Trevor's smile slightly wanes but he certainly can't be disappointed after the last measurement turned up no discernible growth.


"But still, Seth, that's just about an inch of growth. I am totally going to hit 6 ft, I just know it!"


“Hell yeah man, and maybe I can at least get to 'almost 6 ft' like you said, haha. Starting out at 5'8” I'd be more than happy being 'almost 6 ft'!”


“I guess you were right, Seth. It does affect everyone a bit different. I mean, Brooke actually grew the fastest out of all us so far, she's put on like two and half inches.”


“Sorta makes sense, I remember back in Junior High that the girls often grew faster at first compared to the boys. But yeah, man, it's working for Brooke though. She looks extra hot lately. Hope you don't mind me sayin'.”


“Haha. No prob, dude. You can look, just don't touch!”


The two laugh and high five again. Even though Trevor discovered that he is just slightly shorter than what Seth had originally let on, he is still joyous. His confidence that he always remain the bigger roommate returns. That night after the measurements Trevor meets up with Brooke for their last night together before they break from summer. Like him, she will also be away for the summer so they plan a last special night together. After eating at their favorite restaurant the two head home for some intimate time. Back at Trevor's condo, his excitement in the bedroom is palpable and spills over into his performance.


“Woah there, tiger. What's gotten into you? I like it, stud.” Brooke asks, pleased at the sensations he is giving her.


Brooke is also looking taller and more voluptuous than ever, further revving up the horny college stud. He proceeds to give her a heavy dicking from all the excitement at finally growing and making some noticeable muscle gains. He relays the news to Brooke and in the middle of their fucking she wants to be measured too. Trevor excitedly obeys and measure her now at 5 ft 8.5! He thinks to himself how his girlfriend is becoming quite the vixen before the two return to the bed for another round. The two, both enhanced and excited by the results of the Elongro, are able to go longer than they ever had before. The couple drift asleep in each other arms, Trevor dreaming of growing stronger, more muscular and taller than he could've ever imagined.

Part 2:

Everyone breaks for college and Trevor temporarily moves out of state for his summer internship. Not only is he going to be away from Seth but he will be away from Brooke too, a thought that saddens him but he realizes he has a golden opportunity to make some good money over the summer. Money that he can use to buy supplements and food to fuel his continued growth.

However, a couple of weeks into his internship, Seth quickly realizes that while he is making good money, the job also takes up a lot of time. Being the intern, lots of busywork gets dropped on him by the higher-up businessmen. Unfortunately, this requires the young stud to often stay late or work from home in the evenings, meaning he begins to miss many of his workouts.  And if he does get to lift on weeknights he was usually relegated to using his crappy apartment complex's gym. The hard work is also preventing him from preparing his typical healthy meals. Trevor finds himself often eating out at fast food places for lunch due to the lack of meal prep. Soon he notices that he is only lifting on the weekends.

One month later and exhausted, on a Friday evening Trevor and Seth are exchanging texts.

Seth: [Hey man, hows it going! I haven't heard from you in a couple of weeks. How the job?]

Trevor: [Hey bro! Sorry, just been so busy at work, promise I'm not ignoring you. Job is good but crazy busy!]

Trevor reads his text. He knows he should return the question but he's almost afraid to ask. He knows his progress has stagnated or maybe even regressed due to the stress, unhealthy diet and lack of time. He opts for a vague update simultaneously hoping Seth with and will not give an update on his progress.

Trevor: [So how are you doing? How life back in the college town?]

Seth: [It's great, man! I'm working in the dorms as a maintenance handyman. Been helping the supers with basic upkeep while the students are out. It's nothing like what you are making but it's something! And it allows me free access to the student rec center! And gym is going awesome, you taught me well, bro! I'm getting stronger and stronger. How's your workouts going?]

And there it is. The question Trevor didn't want to answer. It's not the most honest answer but he can't help himself.

Trevor: [Yeah man, gym is good. I haven't been able to go quite as much but doing what I can. With making so much $$ I've had to skip a few workout but you know me, can't keep me out of the gym too much!]

Seth: [Haha yeah, dude, you are the ultimate gymrat. I bet you are getting jacked. I bet you've finally passed that 6 ft mark, huh? I can't thank you enough for getting me on Elongro. I'm still growing a little taller, probably not as much as you though. But short guys like me will take whatever we can get, LOL]

Trevor's mind is racing. He's not sure, he hasn't measured himself since he left college, but he hasn't felt any taller or bigger lately.

Trevor: [Hell yeah man. Great to hear. We are gonna be buff tall studs!]

Seth: [I can't wait man! Even with you still being bigger I feel like I'm finally becoming an alpha male, haha! I've actually been getting some attention from more and more ladies. Being big rocks, I see why you were so happy all the time, haha]

Trevor: [Yeah bro, gotta run. Adios!]

Trevor decides he needs to buckle down and find the time to lift big and eat big. He can't let his gut soften up any further.  By this point his abs were only faintly visible. He can't let Seth get more muscular than him.

Unfortunately, it was not meant to be for Trevor. Work became even more exhausting. Working for a marketing firm in the big city was a big eye opener for just how dedicated some of the more senior businessmen and businesswomen were.

The two continued to sporadically send messages to each other.  Same story between Trevor and Brooke. Every time Trevor gets a message from Seth he can feel the energy and excitement behind Seth's words. One message mentions a new hobby for Seth.

Seth: [I was running laps around the courts the other day and these guys asked me to play pickup Bball with them. It was fun! I wasn't nearly as bad as I thought, lol. Been a while since I shot around but I picked it back up fast. I was far from the worst guy playing, lol.]

“Basketball?” Trevor thinks to himself. He never knew Seth lnew how to play basketball. Plus, basketball didn't really seem like his sport, being more meant for...well...tall people.

Seth has been loving his summer job. Sure, it wasn't a big moneymaker but it allowed him to use his hands and burgeoning strength. He could only grin every time the maintenance workers would ask him to help carry the heavy replacement parts and equipment. One of the older of the supers had even taken to calling him 'Mr. Muscles'. The extra motivation was pushing him to lift bigger and heavier weights in the rec center, where he was becoming quite popular with the few college girls who had stuck around during the summer.

The rest of the summer flies by, and before they know it, there is only a week before school starts back up. Seth is already on campus, having decided to live at a place he had found back in July with some guys he met playing basketball. Trevor just returned back in town yesterday and was busy moving into his small one-bedroom apartment. That weekend Seth had invited him to a party at his new place. Trevor had been dying to see Seth, both to catch up with his best friend but also to see if he's gotten much bigger. From Seth's summer progress texts Trevor was prepared to see new mass on his buddy. Perhaps Seth might even nearly weigh as much as himself now, since Trevor hadn't made any progress that summer...either in muscle mass or height. He hoped Seth wouldn't notice how he had actually softened up a bit from his formerly shredded physique. After he got settled in to his new place, Trevor's phone buzzed that afternoon before the party.

[Hey man! Come on over anytime after 7. A few buddies are over too. Bring some beer if you can. Worked out two hours today, and I'm THIRSTY, haha! Can't wait to see you, bro!]

Tervor rolls up to Seth's apartment. There are a few cars there already and music is pumping loud. The place looks packed. "When did Seth meet all of these people?" Trevor wonders silently to himself. Seth has never never been all that outgrowing. Apparently this has been his summer to make a plethora of new buddies. Carrying a case of Bud Light, he knocks on the door and a very tall guy opens. He catches his breath, looking up and up, before realizing that it must be one of Seth's new friends.  He relaxes slightly.

"Yo, Seth, beers here!" The tall guy yells out.

He must be at least 6 ft 5 and just towers over Trevor with a strong build as well. Seeing taller guys has always made Seth uncomfortable, hearkening back to his constant desire to be the alpha in the room. Trevor sees a pile of shoes, takes the hint and kicks off his shoes next to the pile. He notes that they all look huge, with none being under what looks like Size 12. Quite a few seem much bigger than that. Just then he hears Seth, though his voice sounds even deeper than before.

"About time, bro!"

Trevor sets the beer down on the floor and before he can get a good look and say anything back Seth quickly walks and gives him a full on brotastic-bear hug. Only this time Seth leans back, lifting Trevor off the ground! Seth's arms feel like steel as they wrap around Trevor. Trevor hugs back and the reunited friends pat each others' backs. To Trevor, it feels like he's hugging a granite statue. Seth lowers him back to the ground and steps back, his arms on Trevor's shoulders holding him at arm's length for inspection. Trevor notices a wicked cocky grin on Seth's face and soon realizes why. Trevor is...staring UP at Seth.

It's not a glaring difference, but Seth's eyes are clearly above his pal's, just so. Trevor can tell that Seth's has processed this as well and knows what Trevor must be thinking, but he is relishing letting Trevor soak it in. After a lengthy pause, Seth gives Trevor a once over and asks,

"Hey dude, what happened? You look a little softer since I last saw you. I can still tell you're buff but your arms aren't as veiny as they were."

Comparatively, Trevor notices that Seth's forearms are bulging with sinew and veins. Trevor's heart beats fast but he tries to play it off, tries to retain his alpha-stud demeanor.

"Oh yeah, the internship was nuts. I made some great money but it really took away from my gym time."

Seth notices Trevor staring at his arms and he flexes his wrist, really making them bulge. Seth looks...very good. Strong, lean, more muscular. His jaw seems to be more defined, as if his face shed some baby fat. Not to mention...the height. Finally Trevor can't stand it and asks.

"How tall are you, Seth?"

Seth throws his head back and laughs. It's the moment he's been waiting for, even since he saw Trevor, the new smaller Trevor, standing in the doorway.

"Dunno exactly, buddy. But when I had my checkup late last month I hit 6 ft flat! Isn't that awesome! I'm a bona-fide six-footer! And that was like 4 weeks ago.  Haha, dude, but clearly I passed you this summer!  And I've been rocking it at the gym. I benched 225 lbs TWENTY times yesterday bro! It's was fuckin' awesome!! Benching all that weight is easy when you are up to 210 lbs like me, haha! And I'm even leaner than I was at the start of the summer, so I put on like 35 lbs of pure muscle and bone over the last three months!”

Seth is obviously excited and loves bragging about his new progress. Trevor's mouth is agape, all those updates of Seth's progress in the gym weren't exaggerating. If anything, they downplayed his actual growth. Thirty five pounds of muscle is a shit-ton to put on in one year, much less three months not to mention what looked to be like 3 inches in height!  "Where the fuck did THAT come from?  He's actually taller than me now," Trevor thinks to himself.  Seth see's his new smaller friend's shocked expression, gives a wry grin and steps right up to Trevor, chest to chest.

“And how tall are YOU, Trev?”

Trevor gulps, his eyes just slightly pointed up looking into Seth's. He tries to hide his intimidation, forcing a smile back at Seth. Trevor measured himself last week and knows the true measurement but some weird instinct in him fights its way to the surface.

"Well it looks like obviously we grew differently like back in spring, but like you I reached six foot! I finally hit that magical mark too! It's awesome!"

Trevor does his best to act excited like Seth but sees Seth smirk, seemingly skeptical.

"Oh yeah, Trev? Hmm...we will just have to test that out!" Seth says, laughing.

Trevor laughs too, nervously. Thinking the situation was over. Then, to Trevor's horror, Seth calls out to one of the guys in the room.

"Hey Jack, come over here. I want you to meet my buddy Trevor!"

Jack walks over. He's clearly a gym guy too, but he's less developed than Seth... or even Trevor by this point. Seth introduces his former roommate to Jack. The three talk for a bit about your internship, Seth's job and Jack's job. They gab about school and the classes we will take this upcoming semester and just the summer in general.

"Trev, you know Jack used to play basketball? He was a walk-on for the college team last year. Jack is one of the guys I met playing this summer.”

As he speaks, Seth claps his big mit on Jack's shoulder, clearly getting to a point.

"Say Jack, what did you say you were listed on the roster again?" Seth grins as Trevor looks at him with horror, realizing what is coming. Jack responds.

"Coach put me at 6 ft 1 but I'm really 6 ft on the dot. Sure wish I was that tall, haha. Coaches are always fudging the numbers a bit. Would have helped my game having another inch."

Trevor looks at Seth, pleading with his eyes, but Seth is having too much fun enjoying the moment.

"Trevor was just telling me he grew a bit this summer. He says he's 6 ft like you!"

Jack looks Trevor up and down.

"Really bro? No offense but..."

Seth laughs. A deep manly guffaw emanates from his thick muscular neck. He has a suggestion.

"Easy way to settle this. Go back to back! I'll say if you are the same."

Seth beams. Jack shrugs, clearly not minding the goofiness of the whole ordeal. 

Trevor protests, "I haven't done this since I was a kid, Seth. This is silly..."

Seth keeps pressing, enjoying the moment.

"Come on, it'll take a second.."

Historically Trevor would just smile and steamroll Seth and move on. But seeing Seth's new bigger muscles and taller frame, Trevor feels compelled to comply to his friend, something that his new for the former alpha.

With a huff, Trevor submits and turns to face the other direction. Jack does the same. Seth stands in judgment, grinning and chuckling.

"Six foot, eh?" He says once, confidently. "Well, it looks to me you are just UNDER that mark if Jack is six foot on the dot. Jack has you beat, ever so slightly!!!"

Trevor sighs, dejected. He doesn't want to make a scene. Luckily, Jack helps him out.

"No worries dude! I'll grab you a fresh beer. What are you drinking?"

Trevor was clearly fuming, but this gesture disarmed the situation. Seth thinks it is damn funny, but he can sense his now smaller bud's frustration.

"Haha sorry, man. I had to. Shit dude, this is the first time I've ever looked down at you. I must have at about an inch on you right now!”

Trevor turns his head, trying to hide his annoyance. Seth tries to perk him up.

"Hey man, I only tease because like you said, the growth isn't always even. Last spring I grew first and then you did after me. Looks like I got the growth spurt this time. I'm sure you'll get the big growth next and pass me up again, so I gotta tease you while I can!  You seem like you still grew just slightly taller though, so the stuff must be still working for us. Let's keep pushing this as much as we can. I want us BOTH to be huge, Trev!" Seth says, slapping Trevor on the back.

Seth's slap hits Trevor with more force than he is prepared for and he falls forward slightly. Even Seth is surprised at the power you he has exerted on Trevor.

“Geez Seth, easy up. I could feel that new muscle in that swing. You said you were up to 215? Shit dude, you're...big.”

“210, Trev!  Haha, but like you say though, 'NOT BIG ENOUGH'!”

Seth throws up a sudden, short-lived mock double biceps flex and Trevor can see how his arms bulge and fill the sleeves of the t-shirt. They are looking mighty, along with the rest of him. Even though the white t-shirt isn't tight, Seth's build is clear.  His big round delts, his pecs, his wide lats, traps and arms are all evident underneath the light fabric. Clearly the shirt is bigger than the size Large Trevor is currently wearing that is comfortably loose. Trevor wonders how big the shirt is, if it has just one 'X' or, gulp, 'XX' in front of the 'L' on the tag.  Seth continues his humblebrag.

“Yep, I'm still growing thicker too, not just taller. Added two-to-three an inches to all my measurements! Including almost two and a half inches on my arms! The guns seem to really respond to the weights. So did you put on any weight, Trevor?”

“Um just a couple of pounds, not much difference. That internship really fucked with my fitness this summer.”

“Wow, man! So I got like 10 lbs on you. Never thought I'd say that!”

Trevor thinks to himself, “Me neither.” Although it was true that Trevor hadn't put on or lost any weight, he had added some fat. Which means he lost a bit of muscle over the summer as well.

Thankfully, the pairs conversation moves away from their bodies soon after and the rest of night they have a good time. Trevor loosens up, trying and mostly succeeding in letting his size go and enjoys the party. Though, he can't help but note that all of Seth's new friends are...well, big. Both tall and athletic. Very little collective fat could be found at this party. Among the crowd there are only a couple of guys shorter than him, but he sees with disappointment that they are both clearly more muscular, looking like actual young amateur bodybuilders. If Trevor used to have the build of a physique model, these guys could've been stage ready with some diet and conditioning. With their pumped muscles they likely weighed more than Trevor...making him officially the smallest male at the party, a thought that sickens him. It doesn't help that he then notices that Seth looks almost as buff as they do!

Later on the night everyone is starting to get a bit wasted. After chatting with some others, the two friends meet up again out into the back yard. By this time the craziness of the party is starting to settle down and some of Seth's buddies have headed home. With it still being August, it is hot, humid and sticky outside and everyone at the party is sweaty. True to college jock form, Seth and his new friends nonchalantly strip off their shirts to cool down in the evening air. Trevor is quickly in shock at what he sees. A minute later Trevor corners Seth on the deck.

"HOLY SHIT, SETH! You...you are buff. Your chest and arms look HUGE! You have abs, deep ones! Your v-taper is incredible. You are...fuckin' JACKED!"

With a alcohol induced haze in his eyes, Seth smirks back at Trevor and brings his arms up into a double biceps flex. He looks like a tanned Greek god fratboy stud. Nothing like the former short, slim and quiet roommate Trevor used to know. Seth's peaks rise and mound up and outward between his delts and forearms. Seth barely notices Trevor is there as he gets wrapped up in his self-admiration. He stares at his right biceps as he flexes and unflexes the arm. His meaty triceps sag full and heavy toward the ground, rounding out the full and balanced muscular development of his guns.  Eventually he looks back at Trevor...little Trevor. He'd almost forgot that Trevor was standing there.

Seth grins at Trevor. In his inebriated state the inhibitions are gone and he feels powerful. Confident. Superior. And though he can't help it, cocky. For all his time in college he looked up to his roommate, at his good looks, taller height and bigger muscles. And now he had that same guy beat in each facet. Seth smirks at Trevor. DOWN at Trevor and cockily responds.

"Thanks...little dude."

Trevor blanches at the words. “Little dude.” Now he knows why Seth hated being called that.

I always have conflicting feelings about stories like this. Because on the one hand it's insanely hot seeing a little guy become a big cocky alpha and overtaking his roommate, but on the other hand, I always end up empathising too much with the guy who drew the short straw. So these stories are always very bittersweet for me. 'My Brother Moves On' gave me very similar feelings.

You did a really good job with this story and I'm interested to see how you continue it (though it could end pretty well right now). Your prose is great and the descriptions are hot as hell.

Trevor had a set back cause of his job while Seth's Handyman job help him a lot and had more free time to be  at the gym.

Im sure now that they are both  back in school their training routine would be different but Trveor will grow too not as big and fast as Seth but he will grow.


Im more sad about the fact that their frienship is strained cause of it. Seth have new friends that for the looks of it will keep all teh attention on Seth and both of them got new places to live. They still gonna see each other around but their friendship from now on is different. They are not gonna be the Tall bull buddies they once desired to be together and worst of all once Brooke returns from break too she will notice the difference and will be a harder blow form their friendship and Trevor's ego.

It is an interesting take.  Trevor isn't a villain, and I didn't want him to be, so he is a sympathetic character in some way.  There are gobs of revenge stories on here and I wanted this story to stay away from that and more focus on the new, never-before-experienced dynamics between the friends.

I think there friendship will be fine.  Remember, they have only been back around each other one night.  But things will probably be different for sure!
