Chip was in his room and on a walkie talkie with Gadget.
"You really can't make it back tonight?"
"I can't... the earliest is in the morning. I'm so sorry, Chip."
Chip sighed and rubbed his forehead, "It's fine. It can't be helped. You just focus on coming back in one piece!"
"Of course! I know I promised you the 'thing' though..."
"It's fine."
"But you've been holding back for a few weeks, right?"
"It's fine, really."
"I just know you and I have been planning this and stuff kept coming up an-"
"Gadget! It's fine!" Chip shouted.
"You sound angry..."
"I'm not angry! I'm just..." Chip sighed and closed his eyes, "I care more about you than the thing, alright? Please, understand that."
"Okay... I'll make it up for you when I come back!"
"Sure thing! Now go kick some tail!"
"Alright! Later!"
With that, Chip turned the device off and went to his bed to punch his pillow. He was a bit upset because he and Gadget planned on having sex. It was rough being a hero and those two wanted to get rid of stress the fun way. But time after time again, Gadget has been called to do more work and it ruined their plans where she'd be too tired to want to do anything when she came home. He really did care for her more than sex but he was just ready to finally get that 'weight' off his nuts that's been driving him insane for the last few days.
"Okay, Chip, calm down... calm down." He rubbed his temples and sighed slowly. "Just cool down... hmmm..." He went to the kitchen to go grab a treat from the fridge that he has been saving up. He looked in the fridge... and didn't see his treat. "Where is it?? I know I had some left over!"
Just then, the other chipmunk, Dale, walked in... and was eating a familiar looking treat. It was done to the last bit and he ate it up in front of Chip. "Wow that was a good eat!"
"Dale?!! Did you seriously eat MY treat??"
"There was nothing else to eat. Hey, I owe you one, alright? That was yummy as heck!"
"I can't believe you!! I wanted to eat it!!"
Dale heard how angry Chip sounded and blinked, "Uh, I didn't think it was that big a deal... you get it all the time so it's not like it's rare?"
"That's not the point!! I just... UGH! Nevermind!" Chip stormed off to his room.
Dale looked hurt by his friend's words... but then suddenly had a look of anger on his face... he followed Chip to his room and opened the door.
Chip was in his chair and looking up at the ceiling. He saw Dale in his doorway, "Ah, you don't knock now? What else you're gonna do today?"
Dale leaned on the doorway, "We're just not gonna talk about that explosion you just had in the kitchen?"
Chip looked at the ceiling again, "I was just hungry and it really annoyed me seeing my treat was gone. There's nothing to talk about."
"Yes there is. I'd be an awful friend if I believed that."
You're an awful friend for taking my treat."
Dale looked sad at that comment. 
Chip noted the silence and looked to Dale... and sighed as he stood up, "Look, I got a lot on my mind right now. I didn't mean that..."
"Hmph, it'll take more than that to get to me!" Dale crossed his arms, "You gonna tell me what the heck is going on then? I'm just hurt that you're hurt, buddy."
"It's personal."
Dale stepped in the room and closed the door behind him, "There, we're safe. Now spill it!"
Chip smiled... and sighed, "Don't laugh."
Dale held up a hand and placed the other over his heart, "Promise."
"Gadget and I... were gonna have sex today but she's caught up with work again. We've been planning on having sex for a few weeks but things kept getting in the way."
Dale snickered.
Chip got angry, "What did I say??"
"Oh come on! That's it? Why didn't you say so!" Dale went over to Chip and got on his knees in front of him.
Chip's eyes got wide, "What are you doing??"
Dale rubbed between Chip's legs, "If you were horny, why didn't you come to me?" He leaned to lick at Chip's soft penis.
Chip was stunned at Dale's forwardness; he gripped the arms of the chair tightly and was just frozen there as he watched his friend lick his privates. "This isn't something I just tell someone, you dummy..."
"Come on, Chip! Friends help friends." Dale gave Chip a soft smile and kissed his cock, "And I wanna help my best friend."
"Dale... th-that's not necessary..."
"Well too bad, it's happening. You hurt my feelings with your anger and now I want an apology." He started stroking Chip's dick to get it nice and stiff, "Or an orgasm. Whatever 'comes' first!" He chuckled.
"O-okay! I'm sorry! Stop! It's fine! I'll buy you a lot of treat to make up for it!"
"Hmm..." Dale poked at Chip's stiff cock to see it lightly bouncing and throbbing. "Jeez, it's really been a while since you've last came. That's no good." Of course he heard Chip loud and clear but he didn't care as he wanted to do this and he refused to take no for an answer. He went down and started giving Chip a slow blowjob.
Chip grabbed the top of Dale's head, not to stop him... at first. Once he felt how good that mouth felt on his cock... that familiar feeling... a feeling he craved for so long... he instead petted Dale's head... rubbed his soft fuzz... and moaned softly, "D...dangit, Dale..."
Dale smiled during his blowjob and increased the speed of his actions. His friend was horny so there was no time for foreplay! His head bobbed quickly and his hands massaged those needy balls of Chip's. With each bob forward, his red nose would press to Chip's crotch, meaning he'd get a whiff of that strong musk from Chip. As if he needed more proof, that scent was more examples of how in need Chip was.
Chip was starting to feel that 'tickle' in his cock, "O-Okay, Dale, you can stop! I'm getting close!"
Dale responded by bobbing his head faster.
Chip gasped and held onto Dale's head, "Y-You're really serious about this... o-oh gosh...!"
Dale looked up at his friend with his cute eyes, still bobbing and slurping away at that cock of Chip's. He popped Chip's cock from his mouth and stroked it quickly while keeping his eyes of Chips, "I'm not stopping until I see it~" He said before he started repeatedly flicking his tongue under the tip of Chip's cock.
Chip whimpered cutely as he gasped out, "D-d-d-DALE!!" The chipmunk lifted his legs and spread them as he moaned out. He squeezed the arms of the chair so hard that he nearly broke them  as he came right in his friend's mouth. That was a long awaited orgasm and the male enjoyed it greatly. It took his mind a while to realize it but he only felt this way, not from his girlfriend, but from his best friend.
The moment he felt that creamy ooze shoot into his mouth, Dale pushed his mouth back over Chip's dick and stayed there to allow the male to finish his orgasm inside his mouth. He'd swallow mouthful after big mouthful, causing heavy gulping sounds to be heard. His eyes closed and looked as if he was straining: once more, he got a clear hint on how horny Chip was by how much he came. It was almost so much that it nearly shot out of his nose. But the male kept his gulps in rhythm so he'd keep from doing that. It was really arousing on how much Chip came... and Dale was the cause of it! His little fluffy tail even wagged to that feeling as well as from how sweet the cum tasted.
After a few hot seconds, Chip relaxed: his legs lowered, his grip on the chair weakened and his body was starting to cool off after that intense moment. "Oohhh... oh gosh... th...that was needed... so so much... ah, thanks, Dale!"
"Nuh uh, we're not done." Dale got on Chip's bed. He was on all fours and shook his wide rump at the other chipmunk, "You're still horny... and I got one more hole you can cream!"
Chip's eyes were glued to Dale's rather lovely butt. "D...Dale, I'm fine. Really! That blow really did the job!"
"You're a terrible liar." Dale chuckled as he eyed Chip's very erect penis, "Your cock says otherwise."
Chip looked down at his dick and sighed. "Fine... I'm still horny..."
"So, what do ya say? Plow my tree hole?"
Chip smirked at that, "You're awful at sexy puns." Chip chuckled as he went over to his bed to get on it. Once behind Dale, he held onto the male's hips and swallowed a big lump in his throat. He couldn't believe he was about to do this...
"Gadget never let you go anal, so take advantage of this."
"...have you been spying on us when we...?!?!"
"You're kidding, right? The walls aren't thick... besides, you leave the door unlocked."
"It's closed though!!"
Dale shrugged, "That doesn't really mean to stay out~"
"You little...!!" Chip gave Dale's butt a swat!
Dale groaned and covered his face in the sheets. He started to shiver.
Chip looked worried, "Dale? Did I hit too hard...?"
"...harder..."
"...what was that?"
Dale lifted his head and repeated himself, "Harder, Chip! Harder!~" He wiggled his ass to the male. "Isn't that what Gadget loves to say?"
"You...! Stop listening in on us!"
"What cha gonna do about it?" Dale pushed his butt back on Chip's lap to tease that needy dick with his fuzziness.
Chip grinned with an angry expression worn over his eyes. He gripped the hips of Chip tightly before pushing his cock in that winking hole. Thanks to the previous session, he was plenty lubed up and ready to go. He gave that naughty rump a spank before he began fucking it quickly.
Dale's eyes crossed and his tongue rolled out when he felt that thick rod push inside of his butt with no pause. He lowered his ass to the bed and kept his ass up for Chip. His eyes were closed now as he moaned into his arms from the pounding.
Chip kept one eye opened; he was enjoying it greatly but he was also making sure his friend was alright from it all. He watched his friend's ass wobble from each connect his lap did to it. He enjoyed such a sight... it was better than Gadget's butt. It was much bigger... softer even... Chip knew it was just his horny side speaking but... he would have said Dale was better than Gadget!
Dale looked out the corner of his eye to see Chip's face. He was so happy seeing Chip not so grumpy anymore. He grunted from the thrusts but it wasn't nothing his chubby bottom couldn't handle.
Chip looked and saw Dale looking at him... and at that moment, both chipmunks smiled warmly at each other. No words had to be exchanged at that moment for them to know what the other wanted say.
Chip said out loud, "I'm gonna cum again, Dale...!"
"Inside of me, please! You don't wanna ruin your bed sheets!"
"I'd ruin them for you..." Chip said before pushed in deep and paused as he reached his orgasm. He shivered and moaned out as he came heavily inside of the other male's rump.
Dale felt an intense warmth in his gut at that last line... and that same warmth became hotter when he felt those jets of cum shooting inside of his butt. He grabbed the bed sheets tightly and moaned under his breath. He wanted to keep as quiet as he could to listen to his friend's moaning.
Just like that, the moment was over... Chip came back down to earth from his heavenly orgasm and had a clear mind... and he came to realize that this was no dream: he really did just have sexual encounters with his best friend... and he didn't regret it. He rubbed Dale's rump and pulled out of him, "Dale, you're amazing!"
Dale shivered a bit after the pull out and shook his tail, "Oh, now I'm amazing? Before, I was a jerk for taking your treat!"
Chip rubbed behind his head nervously, "Hehehe... don't worry about that. I'll go get some more later. And I'll bring you some too!"
"No!" Dale stood up and tapped Chip on the nose, "I'll leave. You had a rough few days; let me help out!"
"But... you already did so much just now. You didn't have to but you did!"
"And I wanna keep doing good. Relax~" Dale started to head out of the room. 
Chip sat on the bed.. and noticed something; his bed was dry. But that would mean... "Hey Dale?"
Dale stopped at the door when he heard his name, "Sup?"
"Did... did you cum?..."
Dale smiled and shook his head, "A true sub only cares for the dom's pleasure~" With that line, he wiggled his cream filled butt at Chip one last time before opening the door to the bedroom to leave.
Chip just smiled and flopped back on the bed. He looked up at the ceiling and instead of Gadget on his mind, he had Dale in his thoughts. A best friend a chipmunk could ask for.
