theft A Donation From Big Bro

[kurisupei]

Happy New Year, growers! Here's a new story that I wrote, probably the longest one. I took inspiration from "The Lockerroom Thief" by CockTFBoi. I hope you find this good. If this gets good reviews, I'll add pictures. Without further ado, here it is.

 

A Donation From Big Bro

 

Having been left by their father since they were kids, half-brothers Jason and Blake grew up separately. Jason, 26, the older of the two, chose to leave the house 10 years ago to try and live independently. Meanwhile Blake, 18, the younger brother, was left to grow up with his mother. 

 

Jason got a small job when he left and when he had his first pay, he invested in a gym membership. His investment obviously paid off. Seeming to have gotten some of the best genes, he grew up to be 6'2 and 260 lbs of muscle. His body, partnered with his chiseled face, tan skin, and jet black hair could really make many heads turn whenever he walks by.

 

Blake on the other hand, chose to focus more on his studies. In fact, he just finished high school and is now an incoming college freshman. After moving in his dorm and unpacking, he lied down and scrolled on social media and that's when he saw it, his older brother's profile. He looked through Jason's photos and he was wowed by how his brother looked. At 5'5 and 130 lbs, he was nowhere near the looks of his brother. They do look alike but besides their body, Blake's wavy brown hair separates the two.

 

Blake continued scrolling on Jason's profile and he discovered that Jason is now a personal trainer and is actually the owner of the gym near his college campus. Blake put some thought into it and decided that he wanted to turn his body around in college, he wanted to be the heartthrob of the campus.

 

Jason was about to sleep when his phone suddenly vibrated. He checked and saw that someone had messaged him. He immediately recognized the name and photo, it's his little brother and he wants to meet with him.

 

Tomorrow morning came and Blake was nervous as he's about to meet his older brother after 10 years. He looked around and saw huge figure of a man. The man was wearing sweatpants paired with a tank top. His shoulders were wide, his arms defined, his back tapering into a V shape, his legs shaped like boulders.

 

"J-Jason?" Blake called.

 

The man looked behind him and down at Blake. Blake was met with the man's portruding pecs. It was Jason.

 

"Blake? Hey little bro. Wow, you've really grown, young man!" Jason said to his brother.

 

"I can say the same thing to you. Wow, you're huge, man!" Blake replied.

 

"Thanks man, I've put a lotta work into this body" Jason said, flexing his biceps in front of his brother. "So why did you want to meet after all this years?" Jason followed.

 

"I want to be built and jacked, and I think you're the one that can help me." Blake answered, touching his thin arms.

 

"Well, I'm flattered, little man..." Jason smirks.

 

"So, what do you say?" Blake followed up.

 

"Let’s make you huge, lil bro!" Jason exclaimed.

 

Jason really stayed true to his word. He began training Blake intensively. To Blake's surprise, he started gaining weight and really noticed changes happening on his body. After training for 6 months, his weight went from 130 lbs to 150. He saw his abs being visible, his chest starting to portrude, his bicep having a bump. Blake enjoyed these changes.

 

One night after training, Jason and Blake went to the shower room, going into separate cubicles. They were both pumped after working out and Blake was really feeling his body. But Blake wanted to see how Jason looks, so he peeked into Jason's cubicle as Jason was busy showering. Blake saw Jason's wide V tapered back leading down his ass, but the biggest treat was when he saw what was at front. Jason turned, eyes closed, and Blake saw his thick, monstrous 10 inch cock. Blake immediately felt his own cock harden. Blake couldn't help it, he took a picture of his view of Jason and went back to his cubicle.

 

The brothers finished showering. Blake put some shorts on and before he put on a shirt, he flexed a bit in front of the mirror, admiring his progress. Jason enters the room to change, with only a towel on his waist, when he sees Blake flexing.

 

"Feels great huh? Seeing your progress in the mirror." Jason says while smiling.

 

"Yeah but now with you beside me, damn I'm dwarfed." Blake answers.

 

"You'll get there lil bro." Jason says while raising an arm into a bicep pose.

 

Jason flexes his other arm, posing a double bicep. He puts them down and proceeded to flex a couple more poses. Meanwhile Blake can't help but stare at his brother, admiring his frame. Jason sees Blake staring and he smiled.

 

"It's okay bro, you can touch." Jason says to his staring brother.

 

Blake almost instantly reaches for his brother's pecs, feeling the size of it in his small hands. Blake can't help but let out a sigh of amazement. His hands then move to Jason's rounded shoulders, going to his biceps.

 

"Chest is 58 inches, biceps are 24 inches." Jason proudly states, flexing them. He then raises his towel a bit. "Calves 21 inches, Thighs 30 inches" He adds.

 

Jason feels his ego rise, with his little brother admiring his body that he put a lot of effort into. He flexes his abs while Blake rubs his hands on the rock-hard surface, feeling the crevices. Jason turns around, flexing his wide back, tapering into a V-shape. Blake touches the wall-like back of his brother.

 

Blake feels himself getting aroused and his cock starts to harden. He almost let out a moan, but he suppressed it upon realizing. He becomes afraid his brother will see so he stopped and put his shirt on.

 

"I need to go, I gotta pack for the winter break." Blake blurts out. "See you in two weeks, I guess?" He says.

 

"Actually, make that a month. I'll be going out of the country to collaborate with other gym influencers" Jason answers.

 

"Oh, okay then..." Blake says back.

 

"Continue your workouts huh lil bro. I don't want you getting smaller when I get back." Jason cockily teases as Blake leaves.

 

Blake gets home to his dorm, taking his shorts off and letting his hard 4 inch cock out. He takes out his phone and opens the photos he took earlier, looking at his brother’s huge body and monstrous cock. He begins stroking his cock, feeling more and more aroused as he zooms in on his big bro.

 

"Ughhh Jason fuck" He moans. He begins touching his body sensually, making his breaths heavier. He imagines his big bro's enormous pecs, larger-than-grapefruit biceps, washboard abs. He feels himself get closer and closer.

"Ughhh sh- shit"

"Oh fuck uh- huge"

"Ugh ughh"

"oH- UGHHHNN!" With a wave of pleasure, he cums. His cum shoots everywhere. "Ughh uhh" Blake moans and breathes heavily. He then passes out.

 

That's when he realizes, he wants Jason's size. He wants his height. He wants his body, from his strong arms, thick legs, to his heavily muscled torso. He wants all of Jason to himself.

 

Immediately, he went looking for a way to gain what he wants to take. He searched books and the web and after three days, he found one. He got it and he was excited to make his fantasies real. But in the meantime, he followed what Jason told him and he continued his workouts extensively. He chased for growth.

 

Finally, a month has passed. Blake was excited to see Jason again. He was thrilled to show how consistent he has been. In a month, he added about 10 lbs. Not just that, being in his teenage years, he grew an inch in height, making him 5'6 and 140 lbs. He might not be as big and lean as his brother, but he is filling out his frame quite nicely. His chest now pushes out his shirt, his abs more fuller looking, and his biceps now fit his sleeves perfectly. But beyond all of that, he was excited for his plan. He knew that in a short period of time, his biggest desire will be reality.

 

Blake went to the gym before the sun could rise. He knew that Jason has arrived and that he would be working out. Blake was right, he saw his brother right away. Jason was even bigger than last time, making Blake want him more.

 

"Hey Jason" Blake greeted.

 

"Hey lil bro! Long time no see. Damn bro, you're filling out quite nicely." Jason greets back.

 

"You're not getting any smaller either... By the way, I got us this sports drink." Blake gives his brother one.

 

"Thanks bro, perfect timing, I'm about to start my workout." Jason takes a few sips and went on to start his workout.

 

"Great, I'll join you then." Blake drinks his own sports drink and grins, following Jason to the weightroom.

 

Jason starts doing push-ups for warm-up. As he approaches 30 reps, he started feeling off. He felt a strange sensation throughout his body, kinda like the feeling when having an orgasm.

 

"Ughh- oh" Jason groans as he stops his push-ups and falls to the ground.

 

"Hey, you okay, big bro?" Blake asked.

 

"I'm fine, I think it's just my amount of sleep catching up on me." Jason answered unsure.

 

"Here, drink up." Blake handed Jason's sports drink to him. Blake made sure Jason drank of all of it, grinning as he does so.

 

"Alright then, let's help you get bigger. Let's do bench press." Jason said to Blake.

 

"Careful with this one, lil bro" Jason loaded 155 lbs plates on the bar and spotted Blake. Blake lifted it and did 10 reps with it. "Too easy!" he said. Jason was surprised.

 

"My turn, little man!" Jason said, loading 460 lbs on the bar. Jason lifted the bar and started repping. As he was doing so, his mind was flooded with sexual images. He started to get turned on.

 

"Ughhh" Jason started to moan and groan with every breath everytime the bar descends. He feels his cock getting hard so he put the bar back into place.

 

"H-hold on a little" Jason stood up, and went to the locker room to avoid Blake from seeing his hard-on. But blake already noticed it, he smirked.

 

Jason went into the locker room, his mind all over the place. He feels so sensitive. All that's in his mind makes him wanna orgasm. Little does he know, Blake's the one behind it.

 

Blake followed into the locker room and saw Jason. "Hey big bro, what's going on? Come on let's continue." Blake said to his brother.

 

"Blake, oh uhm. I- I'm just..." Jason explains, trying to cover his hard-on.

 

Blake gets closer to Jason. "Come on big bro..." Blake said, touching the tent on Jason's shorts. "Ughhhh" Jason lets out a whimper.

 

Jason doesn't understand what he's feeling, he's not gay, but what Blake is doing is really turning him on. Blake took Jason's shirt off and started lowering Jason's shorts.

 

"You want to help me get bigger, right?" Blake said to his brother.

 

"Y-yes" Jason staggeringly answers.

 

"Good, bro" Blake said as he takes Jason's shorts off, revealing Jason's hardened masculinity, growing into 11 inches.

 

Without any warning, Blake put Jason's cock in his mouth, making him moan. Blake started sucking, working his way on Jason's cock. Jason can no longer suppress his moans.

 

Jason feels this sinking feeling as he nears his orgasm. The pleasure was wild and he feels closer and closer as Blake moves up and down his shaft. A shudder ran down his body and his balls start churning.

 

"Ughhhh fuuu-" Jason cums. Blake made sure to swallow every bit of it as it shoots hard into his mouth. Jason was overwhelmed with pleasure. He fell into the bench behind him, eyes closed.

 

Blake felt himself get taller, he felt his limbs extending and his view getting higher. As his body gets lengthier, the bulk he had put on disappears, his muscles adjusting into his body.

 

Meanwhile, the opposite happens to Jason. He feels his spine shorten and retract. With that, his muscles enlarge, adjusting to his shortening frame. His pecs and arms bulged out, his legs grew thicker.

 

"Wh-what did you do to me?" Jason said upon opening his eyes and seeing his short frame.

 

"You helped me grow, isn't that what we wanted?" Blake answered.

 

"Y-yes" Jason said, but he felt something was wrong.

 

Seeing his brother's enlarged muscles made Blake more and more excited, so he proceeded to the next step. "I'm gonna get so massive with what we will be doing." He said.

 

Blake lays Jason down the bench and grabbed his brother's still hard cock. He rode it and lowered himself onto it. Blake moved up and down, filling Jason with pleasure. Jason's cock started to spew pre-cum. Blake's body started reacting to it. He felt his body start to swell with muscle. Blake touched Jason's hard pecs and squeezed it as he bounces on his cock.

 

Blake feels his body expand outward as he absorbs more of Jason's precum. His pecs start to form, his biceps tensing into a ball, his abs forming crevices. Jason feels Blake get heavier.

 

"Fuck I'm gonna cum again- ohhh!" Jason finally shoots his load inside Blake. Jason's bulk slowly shrank into him. His biceps slowly thinned out, his treetrunk legs became weak, his torso got drained of its size, his chest on which Blake is grabbing on to lowered slowly from being mountains to a flat surface.

 

"Ohhh fuck- ughh!" Blake can't help but groan as he feels his body fill up. He flexes a double bicep pose as his arms expand into mounds of rock. Meanwhile his legs got thicker and thicker, proportioning into his new height. His pecs grow into boulders, rivaling melons, he touches them and squeezes them.

 

"Fuck, yes!" Blake exclaims as he poses his muscles. He went to the scale and measured his height and weight.

 

"6'4 and 270 lbs, damn. Only one thing left." Blake says to himself as he gets back to Jason.

 

Blake stands Jason up and turns him around. "Hey bro, just one last thing and we're done." Blake said to Jason's ear, caressing Jason's cock in his hand.

 

Jason's cock immediately springs back up to life. Jason whimpers as he feels pleasure build up with Blake stroking his cock. While doing so, Blake slides his 4 incher into Jason's hole. Jason moans as intense pleasure fills hin again, but he can't cum.

 

"You're gonna help me grow right?" Blake says.

 

"Y-yes, anything for you ugh-" Jason answered.

 

"Even my cock?" Blake follows up.

 

"Yes, take it. Take my fucking cock."

 

As pre-cum comes out of Jason's cock, Blake feels it slowly dwindle into his hand while his own cock grows and more and more enters Jason's ass. Blake starts thrusting, making Jason feel more pleasure, all as he strokes Jason's cock. Blake's cock grows and grows inside Jason, going into 12 inches. Jason's, however, retracted into Blake's hand, it shrank into 3 inches.

 

"Ughh, please Blake... I need to cum" Jason whimpers.

 

"Not until I do. Ughhh!" Blake cums into Jason's ass the largest he has ever cum.

 

"Ughhh- shi- ughh!" Jason moans as he experiences being cummed in the ass for the first time.

 

The two brothers experience their greatest orgasm, but one while experiencing his fantasy and one while experiencing loss.

 

Jason shoots cum from his now 3 incher, moaning and passing out in the process.

 

Blake pulls out his brother and admires his new 12 incher shooting more load on his passed out brother. He flexes on the mirror he once flexed on with his brother a month ago, but now being the superior one.

 

"Thanks for the donation... little bro." He said as he leaves his brother in the locker room.

[Creeperded]

This is amazing.. please continue it where they go back to their regular lives with their new bodies and Jason wants to give Blake even more.

Oh, I didn't know. Is there any way to move it? If not, I'll just keep that in mind next time.
