Jonah, Marty, Avi (Jonah's Little Brother)

Summary

Jonah invites his friend Marty over to hang out. While Marty waits on Jonah to finish up with something, Avi gets ahold of Marty. Later on Jonah catches them having sex, so he has to punish Avi.

Story

"Tonight, at your place, don't forget," Marty called out to Jonah before they went their separate ways for the day.

"I won't," Jonah told him. What Jonah did not realize until he was home, was that he had unfinished homework that was meant to be due yesterday. Due to that Jonah got to work on it right away hoping to be finished before Marty arrived. They always claimed it to be a hang out, but in reality they just have sex. Only one other person on this planet knows that, and it's Avi, Jonah's annoying little brother who's too curious for his own good.

Their family was just trying to get by, so both their parents worked around the clock, leaving them home alone most of the time. This was fine with Jonah, since it just meant that Marty and him could do it at his house whenever they wanted. The only problem was Avi. He would hear them, learn what's going on, and then pester them. Anytime Marty comes over Avi always tries hitting on him, and being weird.

Jonah always tried telling Avi to get someone of his own. Preferably someone closer to his age. He didn't particularly care about none of that.

When a knock was heard at the door, Jonah stood up from the dining room table where he was working to get it. "I got it!" Avi yelled dashing out of nowhere into the living room to answer the door. Jonah stopped his walking and stared to find out who it actually was. Sure enough when the door was swung open, Marty was behind it in a t-shirt and joggers.

"Oh, you're here," Marty said as Jonah motioned him to come inside. He has done just that and Avi closed the door back.

"I live here," Avi said in response getting a little confused. "Anyways, let me guess, you're here to fuck my brother again?"

"That's none of your business," Marty told him. "So what are you up to?" he asked Jonah who was slightly blushing.

"Avi!" Jonah cried out. "I'm not a freaking bottom for the last time."

"Doesn't sound like it," Avi said making Jonah's face even redder.

"Ignore him," Jonah said, turning his attention back to his guest. "I'm sorry Marty, but I didn't know that I'd be doing homework. I'm trying to hurry up and get it done. You can go into my bedroom and wait, so Avi won't be bugging you the whole time."

"Alright, is it cool if I grab a snack?" Marty asked him.

"Yeah, when it is not," Jonah told him.

Awhile later Avi cracked open Jonah's door to see Marty making himself at home. He continued to sneak inside while Jonah done his homework.

"What now?" Marty asked as soon as he noticed the blonde haired boy.

"Shh," Avi told him, as he climbed up on the bed next to him. "You can't let Jonah know that I'm in here. He'll get mad," Avi explained to him. "Uh, how do I put this. I'm sick of Jonah always getting your dick. He leaves me out of everything, and you're so fucking hot. It's unfair."

"So all those jokes. You were serious about wanting to join?"

"Yes," Avi sternly told him placing a hand on Marty's crotch.

"Aren't you a little too young?" Marty asked him.

"Not at all," Avi told him. "But please, can we do something. Jonah's dumb, it'll take him all night to be finished. You came here for an ass to fuck, and I want to give you mine."

"That's really sweet, but I don't think you understand how bad anal hurts at first," Marty explained to him.

"I can handle it, I'm stronger than Jonah. He once cried because a cat clawed his arm," Avi told him.

"Not the same thing, but okay. Prove to me that you're ready for dick," Marty said with fire in his eyes as a challenge type of ordeal.

"Your wish is my command," Avi said as he got off the bed and began taking off his clothes. When he was done to just his boxer briefs he left them on. After that he placed his small hands to Marty's pants trying to ease them down.

"Wow, I don't even think you're going to be able to fit your hand around my dick," Marty said as he watched in amazement at how eager the younger Beck brother was. Meanwhile Jonah was completely unaware that anything was even happening.

Avi's eyes grew wide. He never once had that problem with his own dick. This meant that Marty had to be bigger. Like way bigger. Marty's cock was starting to get hard from the curious hands, while his mind thought about Avi not being able to hold it all.

"I'll help you with the last part, but you've got to close your eyes and keep them shut until I say you can open them again," Marty told him.

"Okay," Avi said shutting his eyes. No his mind ran crazy with thoughts about what he'd be seeing when he opened his eyes up. His ears heard the sound of his grey boxers sliding down his legs. Marty took hold of his own cock and jerked it off to full hardness, before he allowed Avi to look at it.

With his young eyes now open he gasped seeing the six inches of fat cock before him. "Wow, how did it get so big?" Avi asked. To that Marty had just laughed.

"Come on, you said you wanted it. Show me that you do, or I won't even try giving it to you." With that said Avi carefully placed a hand on the base, trying to wrap his fingers around it. As predicted the tips of his fingers couldn't touch. Avi added his other hand to fill the gap. Now having both of his hands around the runner's cock, he began to stroke his length. "A simple handjob doesn't prove anything little man," Marty said with a grin.

"Aw okay," Avi told him. "I'm sorry if this sucks, I've never gave a blowjob before. Also can I have my underwear off, my boner is really starting to ache."

"Not to worry, poor dick sucking skills might run in the family. Jonah gags every time, so sometimes I'll just go straight for his ass. Speaking of that, yours looks fine and plump, just like his," Marty explained to him. "Oh and go for it, my dick is out, so yours can be too," Marty told him.

When Avi got back a foot or so, he turned himself around bending over to lower his boxer briefs stepping out of them. While doing so Marty quickly jerked himself off while feasting over his hairless ass, with a virgin tight pink hole. Avi then turned back around showing off his not nearly five inch erection. The girth was small, but understandable for his length.

"Does it squirt a lot?" Marty asked letting go of his own dick to point at his.

"Nope," Avi said shaking his head making Marty grin.

"Jonah was the same way, until I made him have a prostate orgasm. Looked like he released the flood gates," Marty said chuckling to himself at the memory. He spread his legs a little as Avi got down on his hands on knees on the bed. Avi wasn't quite sure what to do, but he held the base of the six inches steady as he kissed the tip. He wasn't sure what to expect from the taste, luckily it was nothing nasty. He then parted his lips letting the tip go inside.

Marty watched as his cheeks filled with air. "Avi, pull off a minute," he ordered him. Avi's mouth came up while blowing some air out. "A blowjob doesn't involve any blowing. You're meant to be sucking it," he explained.

"Oh, sorry. I knew what I was doing was weird," Avi said while wondering why it's called a blowjob. He licked his lips slowly in a circular formation before going back down. Marty didn't want Avi to treat him as his master or anything, so he reached his arm forward finding Avi's cock. When he grasped it, he felt Avi gasp around his juicy cock.

"Don't say anything, just keep doing what you're doing," Marty told him, not wanting the head he was getting to be interrupted again. He sneakily pushed Avi's head down lower, trying to hint that he wanted Avi to go deeper. Thanks to his own dick being pleasured, the little Beck brother didn't mind trying to take more into his mouth. He felt like his mouth was full and didn't try anymore after that. Instead he just slowly pulled his head back up bobbing ever so slowly. "You're such a tease," Marty told him.

"Marty, can I please have it now," Avi asked impatiently after pulling off. "I know I said Jonah would be all night, but he's probably googling the answers and cheating."
"I guess, know where Jonah keeps his lube?" Marty asked. Before he got the entire question out Avi ran from the bed with his erection wavering around as he dug through his drawers finding it.

"Yeah, right here," Avi said presenting it to him.

"Nice, now lay down on your back and get comfy," Marty told him taking the lube and applying some to his fingers. He used his other hand to help position Avi while saying, "move your legs out of the way."

Now being spread wide open, Marty smeared the lube across his rosebud making Avi shudder. "Is it cold?" Marty asked already knowing the answer, nonetheless Avi still nodded his head in agreement. "Yeah, it's much warmer inside you," he said to Avi as he applied pressure with one finger until it went inside getting knuckle deep.

"Jeez, how many fingers do you have inside?" Avi asked him.

"Just one, why?"

"Well your one feels like two of mine," Avi revealed.

"Ah, so you have fingered yourself before," Marty said.

"Yeah, also tried out homemade dildos, but they never work out too well," Avi confessed to him.

"Holy cow, you really are desperate for dick," Marty said aggressively swirling one finger around before pulling it out to insert two back in while his own penis throbbed. He was going to get this guy exactly what he wanted. "Anyways you have to be super quiet when I'm sliding in. You'll probably want to scream, but you can't."

"I know," Avi told him. "Can you just do me now," Avi asked.

"Whatever, even though I don't think you're ready," Marty told him. He stopped his magic fingers to get the lube again, this time for his dick.

"Wait, can I put the lube on you?" Avi asked. This surprised him. Marty passed over the lube, and made his cock hover over his small body. Avi pushed out a line down his dick before closing the lube and rubbing it over his thick dick. Marty got a little bit squeamish having those little fingers making his already wet cock now slick. He neared his tip to Avi's entrance. Avi gritted his teeth as he waited in anticipation. Instead of easing in slowly, Marty gave one solid thrust getting a tiny bit past the tip inside all it once. Right away his tight insides hugged his cock while the asshole around rapidly expanded to accommodate for the girth.

"Mnn," Avi groaned steadying his breathing, just like the online guides had told him to. From there on out Marty would pull a little out and ease in further than before. This process went on until his sack came in contact with Avi's bottom.

"There, all the way in," Marty told him. "You really impressed me."

"It's cause I'm better than Jonah," Avi said through a hitched voice trying to cope with the pain.

"Relax, it'll be feeling great in no time," Marty reassured him as he gripped Avi's surprisingly hard cock and jerked him off to take his mind off the pain. The runner took his time increasing his speed until he was fucking Avi at a good rythmn. "Yeah, you're way tighter," Marty said out loud.

It was at this moment that the door opened up revealing Jonah. "Marty!?" he yelled in shock. Marty slid all the way in, stopping and turning his head to face Jonah. "Why are you fucking my brother?"

"He was begging for it," Marty told him. "I also felt bad for him. Come look at him, he's loving my cock," Marty told him. Jonah moved around to the side while getting hard in his pants as he saw Avi on his back, with his legs spread with a fully erect cock sticking up.

"Marty, I don't want you to waste your load on him. Plus you came over here for me. That's supposed to be me getting pounded," Jonah said while getting upset. "Avi get out of here, go find your own dick. Marty's is mine."

"Chill Jonah, we're not dating, I can do whoever I want," Marty told him.

"It's on my bed," Jonah exclaimed.

"Fine, then you can fuck him," Marty said as he withdrew his entire cock leaving Avi feeling empty.

"But," Jonah started to say.

"No one gives a shit that he's your brother. If I had one that loved dick this much, I'd be blowing one up his ass on the daily. You're lucky and should take advantage of this."

"Ha," Avi laughed. "Jonah fucking me. He would never, he's too much of a wussy bottom," he teased.

"Says the one who was just getting plowed," Jonah told him. "Can't believe I'm saying this but fine. Someones got to teach him a lesson about stealing my guest."

Marty stood back and used the time to remove his shirt, while Jonah began stripping. "So how big is Jonah?" Avi asked curiously.

"Oh he's huge. Way bigger than me," Marty warned.

"Then why is he bottom?" Avi asked.

"Why do you? It's because he loves it," Marty answered. Jonah had his shirt off first now being topless. Next that came off was his pants revealing his blue boxers. They came off almost immediately after. There in all its glory was Jonah Beck's lengthy eight and a half inch member.

"Tonight, I'm topping Avi. Cause I'm not," Jonah started to say as he got in position. "A fucking wuss," he finished off giving no warning as he slammed his whole length into his younger brother making him cry out.

"Woah Jonah, take it easy on him," Marty said, even though he didn't mind since the rough treatment made his cock leak out a small bit of pre cum.

"Hell no, he deserves it," Jonah said with anger in his eyes as he swiftly pounded away. Marty got some more lube for his own cock since Avi's ass took most of it off.

"Well can I stick it in you?" Marty asked Jonah for permission.

"Yeah, hold on," Jonah said as he slowed down to a stop waiting for Marty to enter him. Jonah pulled out of Avi and had his ass push back engulfing Marty's length faster than he was giving it to him. "Mnn, that's the stuff, burns so good," Jonah said before resuming what he was doing earlier like it was nothing.

Marty found it super odd that for the first time he was able to fuck Jonah without having to move at all. Jonah did the work, while being sandwiched in the middle. Fucking Avi while fucking himself on Marty.

"Jonah," Avi cried out once more as his cock twitched around. Not long after strings of pearly white cum came erupting out, landing on his chest. Jonah bit his lip at the sight of Avi cumming for him. Jonah just fucked faster making a solid slapping noise against his body.

"Damn Jonah, did you just make him blow, cause it sure sounded like it?" Marty asked while holding Jonah's hips, wondering how fast the guy could actually get.

"Yeah," Jonah breathed out not giving more than one word. He was too focused on demolishing his younger brother's ass. He never wanted to be called a wuss again from him.

"Jonah, I'm not sure if I can last much longer myself, you're going so fast," Marty warned him.

"That's fine, you can finish and pull out," Jonah told him while he couldn't keep up the pace so he slowed down to catch his breath before going crazy fast again. Avi's erect cock rolled around on his stomach in a pool of cum, swearing that he'd jizz a second time.

"You naughty boy, like cock now?" Jonah growled at him. "Or does it hurt too bad for you," he asked before letting the word "wuss," roll off his tongue. Avi squinted his eyes shut and whined. "What I thought," Jonah said as he carried on.

Marty began to give thrusts of his own meeting Jonah's ass halfway resulting in harder pounds. Marty's cock kept striking into his prostate driving Jonah wild. Marty was pretty satisfied at this point. He already got some of Avi's sweet ass, and now he was getting Jonah's tinder cheeks.

The track star gave no warning for his orgasm that came. He let loose while continuing to pound him. Jonah felt the juices being shot out deeply into his ass. When Marty was sure that all the cum was out, he withdrew his cock.

About five minutes later Marty was slowly jerking off on the bed watching Avi's little cock about to burst again. Pre cum had been oozing out, and Jonah's pants had started to quicken. "Go on Avi, squirt again, I dare you," Jonah said huskily.

Avi loved the way he was being talked down to. He let it all out. A loud moan and all that sent Jonah overboard. Avi's cock spasmed and semen came out. Marty nearly drooled at the sight, which only got better as Jonah whipped his cock out from his ass and began jerking off over his stomach.

Jonah held his hand directly under his tip as he groaned, knowing that his orgasm had just arrived. Avi watched as a jet of cum came flying out. It shot further than he expected, and made him dodge his head to the left getting cum to splatter on his cheek. Jonah just grinned showing off his dimples, as more ropes of cum came out after that one. Each one landing lower and lower down on his body. Jonah used his hand and slapped Avi's ass hard. "Go get cleaned up, while Marty and I have our second orgasms. Alone," Jonah told him.
