"Wow, I hardly recognize the place!" Old Man Willy was shocked to see his basement so clean and organized. Jake and Dexter worked hard to create a space that their elderly neighbor had promised them to be their new place to get intimate. 
When Dexter had told Jake about the deal, he was skeptical, but he wasn't about to say no to money and more sex with his older brother. Jake had just turned 11 a few days earlier, while Dexter's 16th birthday was still 6 months away. Despite their age gap, both boys were quite close, and equally horny for the other. A few weeks back they had been caught under a bridge on Willy's property, but the old chimp told them he'd keep quiet. It seemed Old Man Willy had gotten up to some similar shenanigans when he was younger, which made him very understanding of the boys' situation. Now that the dusty mother-in-law suite was cleaned up, the chimp brothers could finally get down to business. 

"So were ya boys planning on sticking around tonight?" Willy asked. Though he wasn't into young boys, he could tell the brothers were a little restless. "I talked to yer mom when you guys showed up this afternoon. She said she'd pick you up at 10."

The brothers' eyes lit up. 10pm was pretty late for them, but it was a Friday after all. It was just past 7, and they had already enjoyed a pizza dinner. 
"She said. 10?" Dexter asked. "Really?"

"She's quite proud of ya two for helping me out. So she said it's a little reward for both of ya." 

"Sweet!" Jake exclaimed, clenching his fists and pulling them to his chest. "Come on Dex, let's have fun!" 

Dexter blushed as Jake tugged him toward the bedroom. He was still a little uncomfortable with how easy going Willy was concerning their relationship, but Jake as always had significantly fewer inhibitions.
"So, uh…" Dexter stuttered, glancing between the wide double bed and the old man. "We'll try to keep our voices down." 

"Nonsense boy," Willy chuckled, reassuring him. "Ya two be as loud as you like. It ain't nothin' these ol' ears haven't heard before. I'll leave ya be, and call down the steps before I come down later tonight." He winked and turned for the stairs. 

His steps echoed all the way upstairs, and the basement door opened and shut tight. 
Dexter breathed a sigh of relief, then turned to Jake who by now had ran to the bed and pulled off his shoes. Dexter smiled and slipped out of his tossing them by the stairs, then slowly walked over to the younger chimp. Jaked bounced happily up and down on the bed waiting for his big brother. Both were still dressed in their school uniforms, which clung tightly to their bodies. The older chimp reached Jake and looked down at him smiling. Stepping forward with his left leg, he placed his knee on the edge of the bed, then his other, straddling Jake. Jake leaned back, giving his brother room to sit on his lap. Now stable and relaxed, Dexter cupped his hands on Jake’s cheeks and brought his face up kissing him gently. MUAH. 
“I love you Jakey.”

“Hehe, I love you too Dex.” Jake wriggled his hips, as he started getting hard. The 11 year old chimp’s healthy member pressed tightly against the front of his underwear. His heart rate increased as he felt Dexter’s hands fall from his cheeks to his collar as the few buttons popped loose. In turn, Jake reached his hands to Dexter’s waist, pulling the older chip’s belt from its clasp. The rustling of their clothes was plenty muted by the softness of the bed and their underlying fur. The two hadn’t had a chance to get intimate on a mattress since before school had started, and both were quite eager for the extra support. 

Although Dexter was still worried a little about having sex with his brother at Old Man Willy’s house, the familiar touch of his early-pubescent little brother quickly calmed his nerves. Feeling his belt pulled loose, Dexter stood back up for a moment pulling off his belt and shirt, while Jake did the same. A now more relaxed smile crossing both of their faces, Dexter returned to kneeling over Jake and the two brothers sank their fingers into the fur on each others’ chests. Their lips met again and their tongues slid between their mouths. 

MMMMMM. MMMMMMMMMM. MWAH!

“So what were you thinking for today?” Dexter asked, knowing his horny little brother was always quick to tell him how he wanted it. 

“I…” Jake panted, catching his breath from the deep and passionate kiss. Leaning upward he whispered in Dexter’s ear, “I want your cock big bro. Please.” 

Dexter blushed, kissing him briefly again. “Ok, Jakey. I’ll give you the whole thing today.” Dexter slumped back only the floor and quickly unbuttoned, unzipped, and yanked off Jake's pants and underwear in one swift motion. Slapping against the bedroom door, the wood slammed closed and Jake’s remaining clothes fell to the floor. Dexter, sporting a devilish grin, then pulled his pants and undies off and stepped out of the leg holes. He was already rock hard and dripping precum. His fuzzy 6 inch cock twitched and his heavy balls pulsed as he watched the younger chimp ready himself on his hands and knees. Reaching back, Jake lifted his tail and spread his butt exposing his puckering hole. Jake’s own balls were barely visible between his legs from the back. Hanging only slightly from his crotch, they were well protected from the savage pounding his body was in for. Stepping forward Dexter grabbed the base of his cock, and rubbed his tip over Jake’s tailhole. Licking his lips, the older chimp could hardly contain his excitement. 
“Ok Jakey. I’m gonna put it in.”

Jake nodded and smiled. “Mmmhmmm. I’m ready.”

“That’s a good boy,” Dexter replied and he pushed his tip forward, slipping it inside Jake’s body. 

Both boys gasped, followed by a simultaneous loud moan as Dexter pushed halfway inside of his little brother. They had both missed the feeling so much! Jake bit his lip feeling his insides spread apart to accommodate such a wonderful cock, which he had grown accustomed to. As many times as Dexter penetrated Jake, he never could get over that first initial moment when he was warmed by the younger chimp’s body. He could feel Jake squeezing around him tight as his tip pushed past his developing prostate, and Jake’s gasps and moans as he did only fueled his teenage lust. Waiting for Jake to give him the nod to continue, Dexter could feel his precum begin flowing and getting sucked out by Jake’s body. After a few minutes of adjusting, Jake finally looked back and gave the go ahead, and Dexter grabbed the younger chimp’s hips and slammed forward.

“Ah!” Jake gasped, feeling Dexter’s full length deep inside him. His pubescent 4 inch cock throbbed as the older chimp began thrusting. A thin bead of precum began forming at his tip, as Dexter slapped his hips against him over and over. 

The old bed squeezed and made light thumps against the wall. It wasn’t very loud, but the vibrations managed to reverberate upstairs to where Old Man Willy was sitting. The elderly chimp was in his recliner reading a day old newspaper. He could hear subtle grunts and moans echoing up through the vents, which made him smile. He didn't dare touch himself to the boys' youthful noises, but his body still reacted on its own naturally. For a brief moment he closed his eyes remembering how his best friend used to rail him at sleepovers growing up. It was a wonderful experience, but only fond memories now. Chuckling to himself, he opened his eyes and went back to reading. The continuing sounds of the young chimp brothers fading out in his mind as he focused on the newspaper. 

"Ah, Jakey!" Dexter gasped. The teenager, now thrusting hard and fast into his little brother. "I'm…I’m gonna cum!" 

"Oh yes, Dex! Fill me up! I want it all!"

"A…AAAAANNNGGHHH!" Dexter quickly slammed his hips against Jake's one last time as his 6 inches throbbed. His balls lifted up as he sprayed his thick cum deep inside Jake's body. 
Feeling Dexter's hot seed splash inside him, Jake felt his whole body shivered with delight. His own 4 inch boyhood pulsed releasing a shorter burst of cum than his brother. His orgasm was much less coming from his boyhood though and more from the depths of his loins. His knees wobbled, and just as the last of the teen's cum filled him, he fell forward in a pool of absolute pleasure. Dexter quickly laid down beside him, rubbing his back gently. 
"H….h….Holy crap, Dex. That was…it was…" 

"Amazing," Dexter smiled, finishing his sentence. 

"Yeah." Jake turned onto his side and leaned up to Dexter. Taking the initiative, his older brother quickly kissed him. 

"You wanna go again?" Dexter asked, feeling hardly satisfied with just one ejaculation…especially knowing they had another few hours. 

"Yeah just…huff…give me a minute."

"Take your time Jakey."

The two would end up having sex twice more that night. Dexter pounded him from behind once more, then lovingly grinded him missionary style over a long 40 minutes. As instructed they balled up the soiled sheets, and put them in the washer. They took their time slowly dressing one another, savoring every last moment of each other's bodies before needing to repress their feelings again at home. As they tightened up their belts a knock was heard from the top of the steps.
"Coming down boys, cover up."

Dexter and Jake giggled and headed towards the bottom of the stairs, picking up their backpacks on the way. By this time Old Man Willy had changed from his daytime attire into a pair of loose fitting sweatpants. As he descended the staircase both Dexter and Jake’s gaze suddenly became focused on the old chimp's pants. Without having to say a word, both glanced at one another briefly in shock. As the old chimp walked the boys could clearly see his cock rubbing against the leg of his sweats. IT WAS HUGE! At least 10 inches for sure if not a solid foot. Despite having cum multiple times each, they both instantly became hard again. Neither one of them had actually seen an adult cock before, even though it was covered by fabric. It was like a simultaneous subconscious switch flipped in their brains, and both knew they needed it. 
"Wow ya boys clean up fast. Ya ready to go? Yer mom's just pulling in now." 

Dexter quickly snapped back to reality, and nudged Jake who was still ogling the old chimp. 
"Sheets are in the laundry," The teen said. "We weren't too loud were we?" 

"No worries boys. I told ya before, ya don't need to worry about yer voices 'round here."

"Hehe, thanks Willy," Dexter replied, scratching the back of his head. "It's great we have such an understanding neighbor. Ok Jake, let's go meet Mom. Thanks again, Willy. We'll swing by next Friday too, if that's ok."

"No problem boys, yer always welcome!" Willy waved as Dexter quickly shuffled Jake upstairs. He remained in the basement even after they made their way outside to head home. Sighing and looking across the basement seeing the bare mattress in the bedroom. He again closed his eyes and thought of his best friend. Though he didn’t say anything to Dexter and Jake, the bed in his basement was the same one he and his childhood friend lost their virginity in. Even in his old age he still had deep feelings for the boy whom he loved. He was rather jealous of the chimp brothers, thinking of a time when the mere notion of enjoying a night with another male was taboo. Despite his loving late wife, his best friend was always the love of his life. Had he been born just 60 years later, perhaps the two of them could have been together like the brothers. 
Open his eyes he reached down the front of his sweats and grabbed his cock, gently tugging on his loose foreskin. 
"If only…" he whispered. "If only you were still here so we could love each other once more." Releasing his member, he sighed again and headed upstairs for bed.

Meanwhile, the brothers had quickly exited through the side door to meet their mom. As soon as the cool evening air hit Jake's fur, he snapped out of his trance and excitedly turned to Dexter. 
"Damn, did you see that!? Old Man Willy is packing!"

"Shhhh!" Dexter quickly hushed him. "We'll talk about it tomorrow." 

"Dex, do you think we can play with it next time if we ask real nice?"

"I said shut up!" Dexter whispered, "What do you want Mom to hear? We'll talk about this tomorrow. So, keep your mouth shut and your dick in check."

Jake grumbled a little, but he knew Dexter was right. Still though, it seemed that their after school time was about to get even more adventurous.
