His amber eyes fluttered open slowly and the first thing he saw was dirty blond colored fur. Alvin smiled a little as he breathed in the scent of his little brother. He blushed slightly and rubbed his nose against Theodore's neck, planting a kiss on the soft skin beneath.

'Theo…' He thought as his hands trailed down to the chubby munk's belly. Alvin began to caress Theodore's soft, silky fur. The smaller chipmunk was still fast asleep, quiet snores escaping his lips as he slumbered peacefully.

Alvin stuck out his tongue and licked Theodore's cheek. The faintest taste of sweat spread along Alvin's tongue, along with the taste of Theodore's smooth skin. Blushing, Alvin started to lick on Theodore's neck and cheeks, giving his tummy gentle squeezes and rubs. 'So cute… and innocent… well, not so innocent anymore…' Alvin thought as he gave Theodore's nose a kiss.

Theodore stirred a little and barely opened his eyes, a soft moan coming from him as he felt Alvin's caring paws against his wide belly. He yawned and rolled over sleepily, his nose bumping against Alvin's.

"Good morning, Alvin…" he said. Theodore giggled as Alvin's lips touched his nose again. "I see someone enjoyed last night…"

"Of course I did… Probably the best night I ever had…" Alvin replied. "You know… It doesn't have to end just because the sun's up…" Theodore whispered.

Alvin's blush grew a little darker as Theodore laid on top of him so that their crotches were touching. "And I really want you again…" he said.

Theodore pressed his lips against Alvin's in a passionate kiss, his bright green eyes closing tight as Alvin kissed him back. Alvin parted his lips immediately for Theodore's tongue, which brushed against his slowly.

*~Theodore's POV~*

Alvin moaned as our tongues touched. He started to suck on my tongue and wrapped his arms around my waist, pulling me closer to him. I felt his paw drag up my body from my hips to my cheek. Our eyes opened up for a split second before closing again. Alvin squeezed my butt hard and I moaned, just to be muffled by his mouth.

He traced his finger up to my butthole, making my whole body shiver against him. I dug my hind claws into the dark red sheets of his bed and wiggled my rump closer to his finger. "P-Please Alvin… Please don't tease me like this…" I begged.

"Shhh… You don't wanna wake everyone up, do you?"

I blushed and covered my mouth. The others were still fast asleep in their beds. I nearly forgot about them, seeing as I was… busy last night. "Pleeease…" I whined quietly as his finger went inside my asshole.

*~Normal POV~*

Alvin pushed a second finger into Theodore, grinning as the chubby munk moaned a little louder and hid his face on his shoulder. "Please Alvin!" came his plea, muffled by Alvin's fur.

"Well… Since you asked so nicely…" Alvin pulled Theodore into another kiss, pumping his fingers in and out of Theodore's asshole. Theo arched his back slightly and moaned into Alvin's mouth. He began to drool slightly and rubbed his crotch against Alvin's. Their sheaths and their balls touched and grinded against the others, urging quiet moans out of both chipmunks as pleasure went through their bodies.

The pale pink tip of Theodore's erection peeked out of the opening of his sheath, leaking out a small drop of precum, which was smeared into Alvin's crotch. "Mmmmmph! Nnn…" Theodore moaned, wiggling his large rear against Alvin's paw. Alvin broke their kiss again and pulled his fingers out of Theodore.

"W-Why'd ya stop?" Theodore whimpered.

"Get on your back." Alvin ordered, giving Theo a gentle push. The chubbier munk just nodded his head and laid down with his belly completely exposed to Alvin, along with his hardening munkhood. "W-What're you gonna do?" Theodore asked.

Alvin laid on top of Theodore and gave his neck a gentle bite. "I'm gonna make you scream." Alvin whispered in his ear. A loud squeak came from Theodore as Alvin sat on his chest, his balls set against Theodore's lips. "Of course, someone's gotta get me hard first." He said.

"Y-Yes Alvin…" Theodore moaned as he breathed in the musky scent around Alvin's balls. His own cock was now completely free from its sheath, a dark shade of pink amongst his fur. The tip was being rubbed by Alvin's tail.

"Go on Theodore. If you want to cum, you'll have to work for it." Alvin spoke, pulling Theodore's face closer to his crotch.

Theodore started to lick and suck on Alvin's exposed ball sac hungrily, letting out quiet squeaks as he serviced his older brother. He was rewarded by Alvin's bushy tail teasing his entire length, even making it leak with precum.

"Aaaahh… Good boy Theodore… Keep that up…" Alvin moaned, petting Theodore's head. Alvin's cock was dripping pre on Theo's face, a somewhat sweet smell wafting to Theo's nose.

He moved a little, this time pressing the tip of his member to Theodore's lips, who immediately began to suckle on it.

*~Theodore's POV~*

I sucked and sucked on Alvin's tip. His taste was better than anything I've ever tasted before. A perfect mix of sweetness and muskiness dancing along my tongue, and I sucked harder, gaining a loud moan from him. In return, Alvin's tail wrapped around my cock and started to pump up and down on me, and I moaned out from around his shaft. I took in more and more of him until my nose was pushed up against his lower belly. I gulped down more of his tasty preseed, and my eyes closed tightly as I bobbed my head along his meat.

"Mmmmnf… Harder Theo… Haarder!" Alvin grunted. He put us in the 69 position and took my length into his mouth and started to suck me really hard. I managed to moan out loud, tracing my tongue on his dick as he milked fresh precum out of me. I wrapped my arms around his waist and pulled his crotch as close to my face as possible, suckling and licking as much as I can.

He groaned loudly and gave my dick a slight nibbling, which forced out more precum. I could hear as he swallowed down the slick stuff, followed by his satisfied sighs as I gave him more and more of my essence.

"Mmmm… That's enough Theodore… Now make me cum…"

I gasped and nodded in obedience. I moved my mouth off of his cock and started to lick on Alvin's asshole, pushing my tongue inside as far as I could. I heard the pure desire in Alvin's voice as he moaned out my name. His cock throbbed hard against my chest, even exposing a few bulging veins as his asshole clenched down on my tongue.

I kissed around his rear, wiggling my tongue against his anal walls as he tightened down on me again. "Theodore! H-Here it comes!" he shouted.

Before I could get his tip back into my mouth, Alvin's hot cum was squirting all over my face, my neck, and my chest. I held my mouth open wide and caught as much of his sweet tasting cum as I could, moaning as he painted my face cloudy white. He slid his tip back into my mouth, feeding me the last few drops of his load, which I gulped down greedily.

He pulled out of my mouth and kissed my nose. "Good boy… Very good… Now it's your turn…" he said, giving me a wink that made my shaft throb.

Alvin pushed me onto my belly and held up my tail.

'Yes Alvie.. Please, please fuck me, big brother!' I thought, wagging my tail in excitement.

*Normal POV*

Alvin mounted Theodore slowly, pressing the very tip of his erection to his hole. "Better bite down on the pillow, Theo. You're still tight." He warned. Theodore squeaked at the prodding and bit into Alvin's pillow, his bright green eyes staring into Alvin's amber ones.

"You ready for it, little bro? I'm not going easy on you like I did last night." Alvin said. Theodore nodded desperately and closed his eyes tight.

The chubby munk let out a muffled scream of bliss as Alvin entered his hole. His claws immediately dug into the sheets below him as he tried his best to hold back his climax.

"D-Damn… Tighter than I thought…." Alvin groaned, resting his paws on Theodore's ass. "You were clenching in your sleep, weren't you, you naughty chipmunk?" Alvin wrapped his arms around Theodore's thighs and pulled him into his lap, thrusting upwards into Theo's asshole. They both moaned out loud, silencing their sounds of ecstasy with each other's shoulder fur.

"It's really hot in here too…" Alvin grunted and speed up slightly, biting into Theodore's shoulder and pushing deeper inside him. Theodore's moans were steadily growing louder and louder as each powerful thrust from Alvin pushed him deeper within.

"I-If… You go... Like that… I-I'll cum early!" Theodore moaned.

Alvin leaned his head forward and dragged his tongue over Theodore's nose and cheek. "I know…" he whispered, his simple words saturated with pleasure and desire.

The older boy spanked Theodore's rump, making him squeak from the pain and pleasure. Alvin quickly pulled out of Theodore and laid on his back. "Ride me, Theo!" He ordered.

Theo was on top of Alvin in a flash, moaning as he spread his tailhole open as much as he could, sitting so that Alvin had full access to his ass. "Put it in me… Please…" Theodore begged as he gave a sultry wiggle of his hips.

*~Theodore's POV~*

I bit down on my bottom lip as Alvin started to push into me. He grabbed both of my feet and massaged the soft, sensitive pads on my paws. For his size, Alvin's cock was pretty big and stretching me out. I could hear him take in a sharp breath as he hilted me, and I let out another moan as he did so. Alvin wiggled his hips and made his cock stir around inside my asshole before he started to pull back out.

"I… I'm ready Alvin…" I whimpered and closed my eyes.

He kissed both of my feet and started to hump me like the wild sex animal I knew he was. Alvin was grunting, groaning, moaning, even growling as he used my ass, each sound from him was met with one from me. My dick was bouncing slightly each time our hips met, precum squirting out of my tip and onto Alvin's chest.

"F-Fuck… Oh God Theodooore!" Alvin practically screamed as he moaned out my name. I leaned forward and got a tight grip on Alvin's well-toned chest, holding myself still as I began to pant heavily. Alvin's breathing became shorter and raspier as our gazes locked together. He forced a kiss upon my lips, and I returned it, my tongue roaming into his mouth.

Eyes shut tight, I started to work my hips up and down with his, our bodies meeting together with a wet smacking sound each time. We were staining each other with precum, his belly and my asshole, and our tongues touched and rubbed together.

Alvin tensed up and rolled us over, grabbing my thighs and pulled me closer to him, his back arching slightly as he went as fast as he can, hitting my prostate each time he slammed inside be. I wiggled my ass more, trying to get him in further into me.

His paws moved from my waist to my own paws, lacing his fingers between mine and squeezing my hands as he dumped more strands of precum into me. I could feel my balls shifting closer to my body as my climax began to build. Alvin looked into my eyes and leaned his head down, dragging his hot, slimy tongue across my chest.

"Do it Theodore… I'm close too…" Alvin whispered in my ear. "C-Cum with me, Alvin!" I whined, closing my eyes tight. Our shafts throbbed, our bodies met together, Alvin moaned in sync with me and pushed as far as he could.

"THEODOOOORE!"

"A-ALVIIIIN!"

He gave one last thrust of his hips and moaned oout my name as our cocks erupted with hot, sticky strands of cum. Alvin pressed his forehead against mine, our bodies rubbing against each other as we came together, staining each other with our seed.

We experienced that awesome feeling of euphoria for several minutes before we slowed to a total stop.

*Normal POV*

Theodore and Alvin were breathing heavily as Alvin pulled himself out of Theo's tailhole. He gave Theodore's member a soft kiss as it retreated back inside his furry sheath.

"How's that for a good morning?" Alvin asked, a tired grin stretching on his face.

"Mmm… Best morning ever…." Theodore sighed, his eyes closing as he pulled Alvin into a hug, enjoying his older brother's warmth and their combined scents. He nuzzled Alvin's cheek and let out a sigh.

"Well now. Looks like you two enjoyed yourselves." Theodore's eyes snapped open as Simon's voice met his ears. "What's he doing on top of you, Theo?" Simon asked.

"Um… Hugging?" Theodore lied, giggling softly as Alvin groaned and stirred slightly. Looks like someone has a lot of explaining to do!
