Chapter 4: Blastoff!

Jake sat in Dexter's lap against the wall of their tree house. The two had been hanging out there all day, eating junk food and playing Uno. However, once the last of the twinkies had been eaten they were ready for a change of food and games. Dexter leaned back and invited his little brother to sit between his legs. The 10 year old chimp was wearing a pair of loose fitting shorts and no shirt. Dexter, his 15 year old brother was also shirtless, but wore a tighter pair of jean shorts which he had somewhat grown out of. They left little room to conceal his adolescent member, which remained semi-hard for most of the day. 

With Jake sitting up against his groin, Dexter quickly hardened completely. The younger chimp was quick to notice his older brother's arousal, and gently wiggled his hips teasing him. Hesitantly, Dexter reached both hands unto Jake's thighs and began messaging them. 
"We shouldn't be doing this, you know," Dexter said, but not stopping his movements. "Mom and Dad are home. They could catch us." 

"Oh come on, Dex." Jake whined. "It's been a month since our last time. Besides, they hardly ever bother us up here. You know…I back there." 

"I know you can Jakey," Dexter replied. He sighed and adjusted his posture. "Ok, just a little bit then." He reached his right hand up the leg of Jake's shorts, and traced up the young chimp's thigh. Stopping at the edge of the boy's white briefs, Dexter reached up and gently caressed Jake's package. Jake wriggled against Dexter every few seconds, returning the favor. 
"Feels like you're starting to get hard." Dexter whispered in Jake's ear. 

Jake giggled, but said nothing. His focus remained on his shorts right where Dexter had his hand. The older chimp rubbed in small circles tracing the shape of his little brother’s boyhood. Jake's warmth felt good against his hand, despite the summer heat. As much as he was worried about the possibility of being caught, he loved watching Jake squirm from his touch. The young chimp's body reacted naturally to the sensation of being played with, and a small but respectable bulge formed in his underwear. 
"Ah, Dex," Jake gasped, feeling his underwear tightening. 

"Boys are you still up there!" A voice shouted. Dexter and Jake suddenly froze, as they heard their dad climbing the ladder up to them. Quickly Dexter pulled back his hand and pushed Jake off of him. The young chimp rolled across the floor and grabbed their deck of cards and quickly dumped it out. He then rolled onto his stomach to hide his obvious erection. Dexter crossed his legs and kept both hands in his lap to make his own less noticeable. Just as they were in position, their dad's head poked up through the gap in the floor. 
"There you two troublemakers are." His arm reached up holding two wrapped and frozen treats up at them. "You're mother though you two would like a popsicle."

"Oh boy!" Jake exclaimed and reached over snagging one of them. He quickly unwrapped it and shoved the bright red stick into his mouth. 

"Thanks, dad," Dexter said, leaning over and taking the other. 

"No problem boys." Their dad replied smiling. "Also your mother and I need to run to the hardware store in town. Should only take about 20 minutes. Will you two be ok up here while we're gone?"

"Sure thing. We were just playing cards anyway." Dexter did his best to hold in the sudden rush of excitement. He didn't want to sound eager for them to leave. 

"That's my boys." He began to climb down, but poked his head back up one last time. "By the way, make sure you remember to put your shirts on when you go back inside. I know it's hot, and I don't really care what you guys do up here, but your mother would blow a fuse if she saw you like this."

Dexter nodded and Jake giggled, then their dad disappeared out of sight. The two boys breathed a sigh of relief and gave each other a smile. As Dexter unwrapped his popsicle, Jake began slowly licking up and down the cold dessert. The older chimp opened his mouth and placed the popsicle on his tongue as he watched Jake casually like his own. 

When Jake was sure his brother was watching, he lowered his head on the popsicle and shoved half of it into his mouth at once. It might have seemed sexy, but the sudden cold to the back of his throat caused him to quickly pull it back out and wince. 

"Phahaha!" Dexter laughed. "Nice try." 
Jake grumbled and went back to just licking the top of it. While Dexter too was licking his own in a similar way, he remained focused on his little brother’s tongue. He watched as his saliva coated the frozen treat, melting some of it and dripping off of one side. They both had to eat quickly as the heat of the day was quickly causing the popsicles to melt. Jake was mostly focused on his own treat, not really watching Dexter at all. This worked in the older chimp's favor, as he was able to gently rub the front of his shorts while watching Jake. It wasn’t really consistent enough to be considered masturbating, but he wanted to stay hard in the meantime. 

Finishing their cold snack at about the same time, both sat back for a few minutes, enjoying the coolness in their bodies. Looking forward, Dexter waved his hand inviting Jake back together with him. 
"Come on, Jakey. Let's pick up where we left off." 
Jake eagerly scooted across the floor and sat back against Dexter. Just as before, the young chimp nestled his butt against his older brother's bulge. He giggled feeling the tightness of Dexter's shorts against him. Unlike before however, Dexter reached down the front of Jake's shorts with his right hand. He cupped it under his little brother’s underwear-covered balls. Jake gasped and looked down at his shorts. 
“Feels good doesn’t it?”

“Ah, y…yeah, Dex.” 

“Good.” Dexter with his free hand turned Jake’s head to the side and gently kissed his lips. "You've got such a great little package, Jakey." He squeezed his hand a little causing Jake to yelp. Smiling, Dexter moved his hand up until he was able to reach into the fly of Jake's underwear. With two fingers, he reached inside and pulled out his little brother’s stiff boyhood. The 4 inch shaft twitched in the teen's hand. 

Slowly Dexter began pumping up and down on the boy's dick. With his left hand, he messaged Jake's chest working his way down to the waistband of his shorts. Jake moaned, watching the tent in his pants flutter around as his brother played with him. By the time his left hand was ready to pull down Jake's shorts, the younger chimp was beginning to leak a few drops of precum. 

Feeling a bit of wetness on his fingers, Dexter pulled back his right hand and used it to grab the other side of Jake's shorts. In one swift motion, he yanked the young chimp's shorts off and tossed them into the corner. Jake giggled as his little dick flopped back into his briefs out of sight. Dexter, seeing this, quickly pulled Jake's briefs off as well. Now fully exposed, the young chimp eagerly spread his legs wide, giving his older brother ample room to touch him. 

Looking up at Dexter's face, Jake showed him a wide grin. 
"All yours now, Dex." 

"Stand up," Dexter instructed him, "So I can taste that delicious little cock." 

Jake giggled and did as he was told. Aligning his young boyhood with Dexter's face, he looked down at the teen. The older chimp's hungry gaze was intoxicating for his little brother. Confidently, Jake placed both hands on Dexter’s head, and guided him closer. Without hesitation, Dexter opened wide and took all 4 inches into his mouth. With his right hand he reached up and fondled Jake's sack, which barely hung at all from beneath his shaft. 

"Mmmm," Dexter mumbled, his mouth full of the young chimp's cock. He loved the taste of his little brother. The boy's thin drips of precum dribbled down Dexter's throat. The sweet musk of another boy was everything the teen needed, yet somehow he still craved more. 
His own pants were now extremely tight, which prompted him to temporarily remove his hand from Jake's balls, and unzip himself. Now released from the bondage of his jeans, the older chimp's boyhood popped straight out of his fly and shot out a stream of precum onto his hands. Dexter moaned from the sudden release, his lips still hilted to Jake's base. Rubbing the precum up to his right fingertips, the teen reached beneath Jake's legs. Reaching up to Jake's butt, he glanced up at him for a brief second to see his lust filled face. Pulling his head back until he was just sucking on the tip, Dexter ran his wet fingers across the boy's hole. 

"Ah!" Jake gasped, feeling the slippery liquid from his brother coat his butt. He squeezed Dexter's head as the teen made circles with two of his fingers. "S…stop teasing me, Dex," the young chimp managed to squeak out. 

Dexter pulled back off of Jake's dick and slurped up the falling drops of his precum. "If you insist." Dexter said with a sly smile. The teen immediately pushed both fingers into Jake's hole causing a loud gasp to escape the boy's lips. The teen pumped his digits in and out, lubricating Jake's inner body. Occasionally he would also flick his fingers in a scissor motion opening his little brother’s hole further. 

"Ah, D…Dex!" Jake moaned louder, his toes curling on the floor. 

Dexter, now satisfied that Jake was wet enough, quickly pulled his fingers out letting the younger chimp catch his breath. Jake let go of Dexter's head allowing the teen to pull off his tight shorts and underwear. Just as his clothes hit the floor next to Jake's, Dexter reached up and pulled Jake down to his knees. Leaning up Dexter closed his eyes and parted his lips, passionately kissing his little brother. 
"I love you, Jakey," he said. Pulling from their kiss, they both looked down at Dexter’s twitching boyhood. "It's ready when you are little bro, take a seat." 

Jake said nothing, only nodded and positioned himself so that he remained facing Dexter and could still take his older brother's cock inside. With his knees on either side of Dexter's hips, Jake lowered down until the teen's tip was probing him. 
"I…I love you too Dex," Jake finally replied, and let his body dip down. His tight young hole parted opened and Dexter's 6 inch cock slowly pushed inside. 

"Ah, yeah!" The two brothers moaned together, their bodies becoming one. 

Jake shivered as the last of Dexter's cock disappeared inside of his hole. Lifting his little brother, Dexter guided Jake's body up and down like a piston. He watched as with each thrust inside, the younger chimp's cock pulsed with delight from the inner pleasure he was feeling. Despite his age, Jake's body was pushing out a considerable amount of precum from the pleasure. It wasn’t as much as what Dexter could produce, but it was plenty to splash out onto the teen's chest. 

Dexter could feel every inch of his boyhood being squeezed tight by Jake. The younger chimp’s muscles rubbed against him, sending waves of pleasure through his body. The intense pleasures paired with seeing the joy on his little brother's face from their forbidden actions pushed him into climax. His whole body tensed and the buildup from his loins came to a head. 
"J…Jake, I'm cumming!" Dexter grunted. He forced the boy's hips down as he thrusted as deep inside as he could. The chimp's hanging balls pulled up against his body and he unleashed his cum deep into his little brother. They both moaned in unison from the sensation. Dexter, from the ropes of liquid ejecting from his loins, and Jake from the feeling of his loving brother’s hot cum painting his insides. 

"Mmmm, yeah!" Jake moaned softly. "This is the bes…o..oh!" Suddenly the younger chimp clenched his sphincter tight and grabbed Dexter's arms. With the last of the teen's juices hitting inside, the younger chimp immediately hit his own climax. Dexter clenched his teeth feeling the base of his cock being squeezed by Jake's hole. The sudden tightening milked out the remaining cum from his body. Looking down at Jake’s twitching boyhood he opened his mouth to try and catch his thin release. Jake gasped as his cock twitched wildly from the pleasure of his orgasm. After a few dry pulses, a single thin stream shot out from him and landed on Dexter’s tongue. Quickly Dexter closed his mouth gulping it down. It didn't have much of a flavor, but there was a subtle sweetness to it. Jake hadn't noticed that Dexter had tasted what little he could produce though. His eyes remained closed as he came down from his peak, and he shivered from the pleasure that had wrecked his body. 

Seeing his little brother trying to gain his composure, Dexter lifted him up one last time allowing his semi-hard cock fall out of the boy's body. He pulled Jake to his chest, pressing the young chimp's member into pubic fur. Hugging him, Dexter gently stroked the back of the boy's head calming his nerves. 
"You ok?" He asked. 

Jake's breath was heavy, but he seemed alright. "Yeah. I just…need a minute." 

"Take your time, Jakey." 

"Thanks Dex," Jake replied, snuggling his head on Dexter’s chest.

Dexter thought for a few moments about how much their relationship had changed since the summer began. School was still over a month away, but he wondered how things would go once everything got busy again. He loved Jake, and didn't want them to grow any further apart. Yet he also knew once they both had access to other boys that was bound to change. Holding him close he wanted to hold him like that forever. 
"Hey Jake?" He finally asked, "Do you think we can keep doing this when summer is over?" 

Jake looked up at him confused. "What do you mean? Don't you want to anymore?"

"No, I do! I love you Jakey. You're my everything…but you know school will be starting before we know it." 

Jake giggled and sat up. "And we'll be in the same school, silly." 
Dexter's eyes widened as he remembered there was going to be just one year when they shared the same building.
"I never want to stop this, either. So if we can't have sex at home, we'll just do it at school."

"J…Jake are you crazy! That's gonna be even riskier than now." 

Jake leaned forward and gently kissed him. "I love you Dex. So, please be my boyfriend. Please." 

Dexter was stunned, but elated. "Oh, Jakey yes!" He hugged him tight and smiled. The summer was far from over, and the two young chimps were once again inseparable. The rest of the summer was going to be amazing…and school was about to become a lot more fun!
