How did Don come up with such remarkable conclusion? Was it because the latest game console was sitting on his desk in various pieces? No. Did it have something to do with comic books lying on every horizontal surface around him? Maybe. The fact that he's the only one in the room that wasn't driven insane yet but really close?
"Donniiiiiie! Entertain meeeeee!"
Or maybe because the subject was curling himself around Don's ankles, very much like a certain Klunk when it's begging for food.
Don felt his head turning into a kettle, with blood boiling inside to a bubbling level. Usually it wasn't this bad, but since Mikey busted the last console Cody bought for him, he's been left with nothing to relieve his boredom. That's saying a lot considering how much his baby brother could do in 2105 without bothering anyone else. Yet somehow right this moment, nothing seemed capable of pulling Mikey away from Don and his work. With a deep, deep sigh to regain his composure, Don pushed away from the machine he's been working on. A bored Mikey is a dangerous Mikey, and if the genius didn't take care of him soon, it might result in disaster.
"You can see perfectly well that I'm busy, yet you're still here bugging me. You must be desperate."
"I know, right? To think there would be a time when I have absolutelynothing to do and have to come to you for entertainment."
Looking down at his feet, Don saw a pair of crystal blue eyes looking up at him with enough innocence to make a kitten jealous, yet somehow the genius didn't buy it one bit. He knew why Mikey would come to him. Not their father for obvious reason. Not Leo the leader, since this time of the day usually would be meditation time, and nothing short of emergency should interrupt him. Raph was also out of the question, since he's still spitting out fire over the life-like bugs that Mikey put in his bedroom. Serling's out for groceries. Cody and Starlee were both here at O'Neil Tech with him, but Mikey ignored the couple to 'bless' Don with his undivided attention. Wonderful…
"Mikey, you know that I have to help Cody with the Time window. Can you play by yourself at… I don't know, the penthouse? Where no expensive equipment can be found?"
"But I'm so bored I can scream. Besides, you always work on that thingamajig. 2015 or in the past, you're always a workaholic. Why can't you go a tinsy bit easy on yourself?"
By this time Mikey had snaked himself up to Don's shoulders, massaging the stiffing muscles. Don would've pushed his brother away, but the way those fingers were moving indicated that their owner had some ideas in mind. It didn't take a genius to guess what Mikey's implying with those suggestive fingers of his. The problem was: this wasn't the time nor place for the youngest to seduce him, especially when Cody and Starlee had started to glance knowingly his way.
"How about this?" Don politely pried those alluring fingers off of him "You'll go back to the penthouse now, behave yourself, and I promise I will play with you later."
"Just the two of us?"
"Just the two of us."
Don didn't remember if there's a time when Mikey could beam any brighter than he did right now, but at least he didn't bother Don anymore. Hopping toward the couple, the youngest pulled Starlee aside and whispered something to her, something that made the blue alien girl blushed and giggled, one hand covering her mouth. Don smiled shaking his head. Whatever they're talking about, it would definitely benefit Don's 'quality time' with his baby brother later, not exactly something he would complain about...
:::
As promised, Mikey was nowhere to be found near O'Neil Tech later on. Don was left to work in peace and quiet the whole afternoon. The only interruption was both Serling and Mikey yelling at them through the wrist transmitter, insisting that they all need to take a break and come back for dinner. Turning off the computer at his station, Don was about to make his exit when Starlee skidded pass him, dropping a small box into his hands.
"What is it, Star?"
"Mikey made it for you." The girl flashed him a smile that made the mysterious one of Mona Lisa's looked mediocre. Something's definitely up. "I don't know what's inside, but he spent the entire morning making it with the Transcendental lathe. You can't look now either. Only when there's just the two of you."
"As I recall, you were with him to operate the device. How come you didn't see?"
"Duh. He made me turn away after activating it. You know I don't put my nose into those boy stuff of yours."
Don found a hard time believing that, especially when Starlee still kept that mysterious smile of hers. Those two were in cahoots together, no doubt. It was a good thing that she's one major fangirl herself and had no problem with them being together around her, just like a certain red haired boy. Don gave up asking, just tucked the small box to his duffel bag and left. When it comes to the bedroom, Mikey could come up with zillion of ideas, some were fun, some were exciting, but there're also some that Don rather not talk about after they're done.
The box was safely put away in a deep corner of Don's closet, but not away from the genius' mind. His head kept drifting back to it and all the possibilities of what its content may be. Judging from the size of it, Don had some ideas of what it could be. Size meant nothing, since Raph's the biggest that he ever experienced, but if the thing was anywhere near Leatherhead's (not that he had a chance to see it anyway), it might pose a problem. Then again, it might not be for him. What's the point of making something fake when Mikey could feel his, the real thing, later anyway?
The genius had no idea how absorbed he was toward the secret content of the box, not until he nearly jumped out of his shell finding Mikey lying on his bed, his gear neatly removed and put away next to the nightstand (for once) and his mask hung loosely around his neck.
"Jumpy, aren't you?" The youngest grinned, his fingers twirled playfully with his mask tail. "Never knew a little dirty thought could keep you occupied like that. You barely answered Cody during dinner."
Now that Don thought about it, he did pay dinner conversation little to no attention. How could he miss something like that?
"Alright, Mikey. You got me. What did you make back there with the TL?"
"Why don't you find out yourself? You're gonna like it."
Don eyed his brother carefully before extracting the box from its hiding place, didn't forget to lock his door. He swallowed the lump of excitement in his throat, trying not to be too obvious about it. Mikey surely enjoyed watching him as much as humping him, and the genius didn't want to give him such satisfaction... yet.
"You made me a... backward jockstrap with a tail?" Don stared at the object inside with an incredulous look.
"Dude, that's all you can see? I'm hurt."
Flipping the object in his hand for closer observation, Don couldn't find out what's so special about it. They don't wear much clothing, so his knowledge on this matter was rather limited. Not that he didn't do any research, he just didn't go that deep on sexy underwear or kinky stuff relating to it. He did see a rubber cylinder at the end of the tail, which was actually a tube, and the strap of the jock along with its cover fabric were a bit thicker than how the material appeared to be.
"The night's still young." Mikey crawled on all four to the edge of the bed "Want me to show you how it works?"
It didn't take much to convince the genius to join bed activities, but his baby brother cut no short in his effort to lure him over. The way he twerked his hip, leaning on his elbows that makes his shoulders slant almost made Don's mouth water. Must be something they planned beforehand, for Raph and Leo put up as much of a show as Mikey every times they wanted to court him, and it's not something they did often toward each other. Just for him. Only him. Don always felt a bit touched and proud of himself knowing how much his brothers cared for him, even in the most erotic of way.
Didn't let his baby brother waited for too long, Don strode toward him, removing his gear on the way. Mikey met him on the edge of the bed, capturing his lips in a heated kiss. Sea green hand took the peculiar underwear from him and tossed it on the bed. The toy was temporary forgotten as they both got lost in each other, hands roaming free to touch the most sensitive spots they knew only too well. As Mikey pulled him tumbling forward, Don was rolled flat on his carapace. Their lower plastrons grind together, adding pressure to the growing bulges beneath.
"Let it go, Donnie-boy. Tonight it's all about you." Mikey whispered to his ear slit, making him shudder in delight.
With a deep churr, Don dropped down. His cock twitched to the cool night air, waiting to be claimed however Mikey saw fit. But the youngest ignored it completely, only focused on trailing his tongue down Don's side, right where plastron meets skin. The wet sensation caused him to bite down on his lower lips, but not before more churr erupted from him. Rough hand trailed along his inner thighs, giving him goose bumps. Just when Don was about to whimper from impatience, which was something he rarely did, Mikey reached for the jockstrap. He slowly slid the toy up from Don's ankles, pass his knees and over his butt. The backside fitted his buttocks like a glove, saved for the tube poking out from behind. The youngest was careful enough to slid the waistband pass his expanding dick without touching it.
"Perfect." Mikey smirked checking out his handiwork.
Don still had no idea of what this toy could do, but when Mikey climbed back up to straddle him, his rear bumped into the throbbing cock, a guess started to form in his head.
The sea green turtle grabbed the cylinder, putting it over his own cock. The rubber moved as if it's a living creature, enveloping his erection. At the same time Don felt something touched his entrance. Many times of intimation with them all, the olive green turtle was too familiar with the shape to tell. But that's impossible. Mikey was sitting right in front of him.
"Mikey..." Don gulped, more from anticipation than nervousness "Is that what I really think it is?"
"Not a mind reader here bro. You gotta tell me exactly what you're thinking." Mikey said lewdly, wrapping his tail around Don's cock. He had to know about the lump poking his puckered hole.
"There's something with the shape of your penis's about to penetrate me."
"But it is mine, Donnie." Mikey leaned close, trailing saliva over his collarbone. "The nanobots in the fabric are programmed to mimic every inch of whatever's inside this tube, which is yours truly right now."
"Not to pop your bubble, but how's this about me?"
Instead of answering, Mikey slowly slid himself down, using his tail to guide Don's cock toward his waiting entrance. The moment Don slid inside, he felt the 'thing' behind him pushing in as well, along with something slick enough for it to enter without much difficulty. Mikey definitely prepped himself already, for he completely enveloped him with ease, and the other cock also fully impaled him to the hilt. Leaning down for a quick kiss, the youngest breathed:
"Now's the fun part, Donnie. Just remember: Whatever you do to me, you will feel the exact same thing."
To demonstrate his word, Mikey gently swayed his hip. Don gasped. As his cock moved to every corner inside his brother, the other cock also moved with the same pattern. Mikey suddenly wrapped his arms around him, sandwiching his erection between them. He gasped and trembled as if he just had an orgasm:
"Oooooh yeees, D-Donnie!" Mikey tried miserably to steady his speech "This is amazing!"
"Wha-what is it?" Don held on to his baby brother breathlessly.
"The cylinder... It makes me feel like I'm actually inside you."
Gently pushed his brother back up and steadied him in his arms, Don glanced down at the rubber casing Mikey's member. It contracted and expanded in sync with Don's movement. When he flexed his ass, it tightened on Mikey; relaxed, and it eased down. Surged up to capture the youngest's lips, the genius stroke the back of his head, whispering to his ear:
"Thi-this is the best thing you've ever done so far. Making us feel what the other feels is brilliant."
"I-I'm just that good, bro." Mikey turned to lick at his neck "I don't mind a threesome, bu... but none of us can move in sync like this."
It couldn't be any truer. No matter how hot it was making out with two or all three of his brothers, they could never get into a rhythm that can shoot him sky high like this. Don leaned forward, easing Mikey on his carapace. He set a slow, deep thrust into his mate, churring loudly when the cock inside him moved with the exact pattern. The best part was, the cylinder already took care of Mikey's erection, leaving all four hands free to explore and stimulate each other further. Don traced down his brother's bridges, gripping it tight to milk out those delicious sounds, since Mikey's sides were as sensitive as his tail. Sea green hands reached up to his neck, digging nails to his collarbone, sending shiver through his spine.
Without noticing, Don was picking up the pace. But it was too soon. The sensation of having his cock buried inside someone while another penetrated him never felt this good before. He wanted this to last as long as possible. Mikey must have had the same thought, putting his hands down his olive green thighs to find some leverage. The youngest had to bite down on his lips to will himself to relax, for he had absolute no control over this.
Don leaned down for a quick kiss to calm Mikey, before lifting one of his leg up, flipping him to one side. Thrusting in from this angle rammed the youngest's prostate with full force, and Don felt the same treatment as the other cock pushed in even further.
"Aaah... AAaah...! Do-Donnie!... Soo... good! M-More!"
"Y-you got it! L-love ya!"
Coherent words became extremely difficult to form as their spots were both stimulated to the bursting point. The only thing that stopped the genius from plowing into his mate was the thought to make this last. Gripping Mikey's hip to pull him as close as possible, Don maneuvered his brother on all four. The tube now dangled between their legs, with one end connected to the cylinder, the other to the jockstrap. The next thrust set fireworks off in their entire bodies, Don almost collapsed onto his brother. The youngest, on the other hand, threw his head back as his arms gave up on him, burying his face to the mattress a second after.
"Fuuuck! DON!" He screamed in ecstasy "More! Give me everything you've got!"
His order was carried out with enthusiasm. To hell with control! Don couldn't take this any longer. The pleasure had escalated to the point of torture. Again and again, the genius pounded on his mate with brute force nearly rival their hothead brother. One hand rubbing sea green tail, the other steadying his brother's side, Don flexed his ass onto the cock inside him, and Mikey instantly howled in pure bliss.
"GOD! Donnie! I-I'm gonna... gonna.." He was whimpering now, bitting and clenching on the bed sheet.
"G-Go! I...I... HGN! MIKEEEEY!"
Don nearly bit on his tongue as he plowed forward, hearing his brother's muffled scream vibrated through his shaking body and the mattress. They both climaxed at the same time, shot after shot of hot cum filled the youngest as Don collapsed on his carapace, sensing the throbbing artificial erection pump something inside him. He wanted to ask, to speak, but his brain didn't function properly and his throat refused to obey him, not to mention the orgasm almost made him black out along with his brother. Only when he's totally spent, Don found it in him to prob one trembling arm on the bed, lifting himself up:
"M... Mikey, I... felt something... inside..."
"That's... my jizz for you, bro." The youngest gulped, pulling himself back together "The tube... pumped it..."
Didn't need for his baby brother to finish, Don leaned down to kiss the top of his head, then gently turned his head around so he could kiss on panting lips.
"That was... incredible." He rested his head on sea green neck "Best idea ever, Mikey."
"Anything for you, brainiac." He grinned "Sleep tight, Donnie."
"You too, knucklehead."
Spooning his brother into his arms, Don drifted to dreamland before he knew it, didn't notice Mikey reaching for something on the night stand...
:::
The genius' internal clock failed him for the first time. Don stirred himself awake in slight frustration listening to the alarm. Like Leo, Don rarely relied on the device to wake him, even when he worked late into the night, or pulled an all nighter. He sat up to realize that the jockstrap was gone, his cock tucked inside, and he was alone in his room. Mikey must have woke up before him and went to make breakfast. The next movement made Don froze a bit, the butt plug grazing his prostate.
"Michelangelo..." He muttered under his breath. Don must have been really out of it that Mikey could work the toy into him like that.
Strangely enough, the genius decided to keep the plug where it was, tucking his tail up to hide it before making his way to the kitchen. Mikey was tossing pancakes around, with Raph and Leo already at the table, huddling to watch something on the leader's transmitter. The moment they saw Don, both shot him a look that could strip him naked right on the spot.
"Morning, guys." He carefully sat down, minding the plug "What are you watching?"
"An experiment." Leo answered, a smirk spread on his lips. "One that had outstanding result, but still need further testing."
"Ya really outdid yerself there, Donnie." Raph put in "The field test is a complete success."
Don arched his brows in confusion. Leo held out his arm so he could take a look at what's showing. His face immediately matched Raph's mask.
"Mikey!"
"Shhh, not too loud, bro! Cody and master Splinter can walk in here any minute."
"You recorded our session?" Don hissed, still couldn't believe what he just saw.
"It's only between us. I just thought Leo and Raph might be interested in this."
"Oh we're interested alright." Raph leaned in close "Not to mention a little insulted. Whaddya mean we're not in sync?"
"He meant our teamwork needs some fixing." Leo cocked his head in total amusement "And I don't mind doing so for all of us. Looking forward for tonight, little brother. By the way, Mikey told us about the plug."
This could be either a very long day, or very short...
