Rapage commission: One for the team

The sound of loud grunting noises echoes through the long cylindrical sewer tunnels, breaking the repetitive dripping of water here and there and the skittering of small vermin. Accompanied by these deep guttural utterances is the clanking of metal on metal and heavy thumping, as well as the occasional battle cry of a male voice.

Deep underneath the streets of New York City, four anthropomorphic green turtles the size of large men are working out in the gym of their improvised home in the sewer system. They’re huffing and grunting as they do, each of them only clad in some sort of cloth fundoshi around their waists, some engaged on their own whilst two others spar with each other. Donatello, marked by his purple bandana, is the technophile of the bunch and has tinkered with many of these dumped workout machines they got from alleyways to not only repair them but also adjust them to their specific needs as large turtle men. He’s also the tallest and least bulky of the group, all four of these turtles being brothers to each other. Then you have Raphael with the red bandana, by far the strongest and bulkiest, currently lifting huge weights and sweating profusely as he grits his teeth with each pump. He’s the muscle of the group and can have a short fuse, though his brothers know that underneath the macho facade resides a warm and kind heart.

Michelangelo is the goofball of the family and likes to joke around, hating it when situations require serious thought, something he prefers to delegate to his other brothers. He’s the smallest of the bunch and wears an orange bandana. Mikey, as he’s often lovingly referred to, is currently holding a large leather pad and playing a moving target for his oldest brother, Leonardo, to hit and kick. Leo, marked by his blue bandana, is the pensive one. The one who’d rather think twice before striking. He possesses some of the bulk of Raph and the brains of Donny, but is by far the wisest of the four ninja turtle brothers and likes to think he’s the most disciplined one as well, guiding his brothers through each situation they run into.

And they run into a lot of those. Just earlier today, they had another encounter with the Foot Clan, a criminal organisation utilising martial arts and subterfuge to further the nefarious plans of their leader, Shredder. It has become a routine for them at this point, but there’s always the risk of civilian casualties, which they want to avoid at all costs. They fought wave upon wave of the enemy, saving their good friend April O’Neil from yet another situation in which she stuck her journalistic nose into, and came out of the battle more sore than hurt. April had shown some of her own improvements in self-defence, seeing as she gets into trouble a lot, and the turtles were genuinely impressed with how well she had helped fight off the Foot Clan.

As the turtles are working out, their session drawing to a close, a kind older rat man enters the room, the bunch’s adoptive father and sensei whom they call ‘Master Splinter’:”Boys, I will be heading out to spend some time and catch up with an old friend. I expect to be home late so don’t wait up.”
Each of the brothers had ceased their activity as their father had entered the room and nods to him, Leonardo wiping the sweat from his face with the back of his hand as he softly continues to move from one foot to the other, remaining in motion:”Alright, master Splinter. Have a good time.”
Splinter smirks and seems to tally a second longer than he needs to before turning around and slowly walking out, speaking up loudly as he leaves:”Be good and behave. Alright, boys?”

The four brothers resume their routine until they hear the echo of the metallic door closing in the distance, Michelangelo immediately dropping the leather pad as he seems giddy with anticipation:”Alright, dudes! Dad is gone and we’ve got the place all to ourselves! You know what that means!”
Donatello smirks in bemusement, gulping down some water from a bottle as it spills from the corners of his mouth and all over his nearly-naked body, the fundoshi around his hips getting a bit more wet:”No idea what you mean, little brother.”
Leonardo is still jumping from one foot to another in place, striking out his arms at an invisible enemy every few seconds as he speaks to his younger brother without looking away from the wall:”I suppose it’s been a while. Don’t get carried away, though.”
Raphael who had been sitting at his bench wipes away the sweat from his brow and seems slightly agitated at Leo’s remark:”Don’t be a Leo, Leo. If Mikey wants to have some fun, let him! Hell, we could all use some fucking relief.”

Leonardo finally stops moving and seems to roll his eyes up into his skull as he sighs, stretching his arms and body from one side to the other:”Alright, alright. Jeez. I’m just saying, don’t let dad find embarrassing stuff… like last time. It was already so hard to explain.”

Michelangelo grins widely as he bounces from Donatello, jovially and lightly punching his brother in the arm before moving to Raphael and embracing the largest and bulkiest of his brothers as Raph is still sitting down:”Cool beans! Thanks, bro! Say, funny you should say ‘cause I’ve been wanting some quality time with you.”
The large and muscular turtle raises his eyebrow and looks somewhat suspiciously as he smallest brother is hugging his side, Raphael already able to feel the rising excitement underneath his brother’s loin cloth:”Oh yeah? Like how?”
Mikey jumps up and sits down right in front of his strong brother, grinning wide like the cheeky monkey that he is and nuzzling his nose to Raph’s:”Because it’s your turn, bro. You know, the arrangement?”

Raphael’s eyes widen slightly and one could be forgiven to think a light blush is appearing on the turtle’s cheeks. The muscular reptile man looks around at his other brothers, Leo keenly avoiding his gaze as he pretends to focus on his after-workout stretches, and Donny is just smirking lightheartedly as he stands up and starts to unfold his fundoshi. Raphael turns back to his smallest little brother and sees the glint of excitement and anticipation, as well as adoration and love, shimmer in Mikey’s eyes:”Please, Raph? You know how it always makes me feel so special when you allow me, err, us to?”
The muscular turtle with the red bandana is keenly aware of the adoration and deeper love that Mikey always seems to have had for him, mirroring himself to Raphael as a role model. Raph seems to blush a bit deeper and keeps a stern face as he doesn’t want to show how he actually very much loves the idea of submitting to his brothers in an officially allowed unguarded moment, speaking softly:”Well, alright then. For you, Mikey.”

Michelangelo cheers and drums the palms of his hands on the cushion of the bench underneath them in excitement, Raphael standing up and starting to unfold the cloth around his waist, “Shouldn’t we shower first?”
Mikey just scoots forwards and is greeted with the sight of his larger muscular brother’s soft humanoid penis, the sheer size and girth would be enough to strike fear in the hearts of many, and hugs himself to Raphael’s groin as he nuzzles his nose and cheeks into his brother’s cock, taking in his manly scent:”Not a chance, bro! I love you like this.”
Hearing Mikey say this softens Raphael’s macho demeanour somewhat and he smiles down as he places his hand on top of his brother’s head:”Love you too, bro.”

Michelangelo doesn’t give Raphael much time to stay in that sweet moment, as his next action is to simply lift the fat cock of his brother up and slide it inside his mouth, the cheeky turtle moaning as he feels his sibling’s foreskin roll back and reveal the juicy fat cock head as it slides onto his tongue, overwhelming his senses with Raph’s taste. Donatello, who had been observing the sweet moment between his brothers, now walks over to stand next to them as naked as the day he was born, smiling meekly at Raph who reciprocates the gestures as his hand remains on top of Mikey’s head. Leaning in, Donny presses himself to the broad turtle and his lips find Raph’s, both their eyes closing as their tongues invade each other’s mouths in a passionate swirling kiss.

Raphael’s hand reaches down and starts to fondle Donny’s semi-hard penis as well as his balls, the turtle with the red bandana still standing over the bench with one leg on each side of it as Mikey sits on the workout equipment and leans forward to suck his brother’s now very-hard dick. Leo is glancing over as he finishes up his after workout routine, a slight sting of jealousy in his heart as he sees his brothers already moving their party forwards without him. He can feel his own cock straining for freedom and he sighs as he unfolds his fundoshi, his penis jumping out and up as it already starts to leak precum. He joins his brothers on Raph’s other side, the larger muscular turtle stopping to french-kiss Donny and looking into Leo’s eyes with a slightly rebellious look. Leonardo stares back but then feels Raphael’s arm wrap around his waist, drawing in his oldest brother closer as their lips find each other as well, a passionate swirl of their tongues sealed with their moans of intimacy and pleasure.

More moans are elicited from Raph as Mikey has stopped sucking his dick, the glorious penis of his older brother shiny with his saliva, and is now sucking Raphael’s large balls into his mouth slurping hard on them. All four brothers know the ritual; each of them is gently encouraged to follow an order where one of them would be the object of all of their attention at once, and usually submit to each of them. Raph being naturally dominant sometimes needs a reminder to give back to his brothers, but since he never can say ‘no’ to Mikey it usually works out. Donny and Leo are battling over Raphael’s tongue with their own, their hands roaming the sweaty muscular form of their strongest brother as well as each other’s. Mikey now lays onto his back onto the bench with his head between Raph’s open legs, taking hold of Raph’s thighs and leaning up to gently lick the sensitive pucker in between his brother’s muscular buttocks. A shudder runs down Raphael’s spine as his cock starts to leak precum all over Mikey’s stomach in response to his little brother’s administrations:”Mhm, Mikey. Your tongue is the best, bro.”

Michelangelo is drinking in the scent of his older brother’s body, the muscular form still coated in a sheen of light sweat from the workout, the younger turtle’s tongue diving in deep as it swirls and thrashes inside the tightly confined space. Leonardo on the other hand is now slowly squeezing and pumping away at his muscular brother’s meaty cock, milking more droplets of clear precum from the cock slit as the strands ooze down onto Mikey’s stomach. Donatello is still passionately kissing Raphael and fondling and massaging his heavy balls, the sac rising and falling in excitement as Raph is stimulated by all three of his brothers at the same time. Raphael himself has both his hands around Leo and Donny’s waists, pulling them into himself as their cocks rub against his muscular thighs and coat his skin with sticky little smooches.

Eventually Mikey’s tongue withdraws from Raphael’s slick anus and the smallest of the brothers coyly and cheekily squeezes his muscular brother’s buttocks:”There, all nice and slick. Can I go first, Raph?”
Raphael grunts, the moment come to make true on his word. The sweaty muscular turtle man with the red bandana moves away from his three brothers and kneels down onto all fours on the gym mats near the boxing ball, cracking his neck and hitting himself on the chest first:”Alright. Let’s do this. Come, lil’ bro.”
Michelangelo doesn’t need Raphael to invite him twice, the smallest of the brothers eagerly climbing on top of the hulking giant that is his older brother and in a momentary gesture of brotherly love kisses Raph on the cheek:”Thanks, Raph. You’re the best.”
As Mikey lines up his green cock, with the beautiful juicy mushroom-shaped cock head, with his sibling’s hole, Raphael seems to grunt and puff out his chest some more as he pushes up his thick muscular ass:”I know!”

Then the room and the nearby sewers are filled with the longest drawn-out moan as Mikey’s cock sinks smoothly and firmly inside of Raphael’s ass in one firm push, the oral prepping having done its magic. Raph grits his teeth and although he’s tight, being the one to take cock the least of all four brothers, he doesn’t want to show his initial discomfort and show weakness to his siblings.

Steadily, Mikey starts withdrawing his trembling penis from his brother’s hole, only to sink it back in with a lustful moan. He finds his rhythm, holding on tight to Raphael’s thick muscular ass as he slaps the cheeks now and then. Leonardo steps forwards and in front of his macho brother, looking down somewhat seriously as he offers his leaking cock to the somewhat scowling turtle:”Do you want to, Raph?”
Raphael’s eyes remain connected to Leo’s a bit longer, the macho turtle huffing softly as he then looks directly into the precum-oozing slit of his brother’s cock and opens his mouth to take the delicious meat inside. There has always been some tension between Raphael and Leonardo, their two personalities clashing more often than not, but deep down they love each other as brothers. Even if they can’t vocally voice those feelings.

Donatello is standing to the side and masturbating, no really feeling eager to settle for a hand job from the turtle in the middle as he seeks a better way to await his turn at Raphael’s sweet virginally tight ass. He first starts rubbing his dripping cock all over the hard ridges of his brother’s shell, coating the surface with his scent before he drops down and semi-underneath Raph, lining up his own member with his sibling’s. The plump tips, half-emerging from their foreskins as they leak copious amounts of natural male lubricant, give each other a sticky smooch as Donny presses up his hips and starts to actively frot with his brother:”Mm, you’ve always had the thickest heaviest dick of us all, Raph.”
Raphael’s chest seems to swell slightly in pride as he curves his back some more, Mikey moaning out lewdly and somewhat whorishly as the former proudly proclaims whilst not even dropping Leo’s cock from of his mouth:”A-h knoww!”

When Michelangelo withdraws his cock briefly to reapply some spit, even scoop down some of his brother’s sweat into his ass crack to lube him up again, Donatello eagerly hands his younger sibling a vial of faintly-glowing purple goo:”Use this, lil’ bro!”
Mikey grins, glad that his oldest sibling is looking out for them with trendy lubricants in his pockets, and he pours the sticky fluid onto his shaft. He massages it into his skin, which elicits a tingle, and then slides it right back up Raphael’s ass as the muscular turtle grunts out in pleasure. The turtle man with the orange bandana takes hold of his older brother’s shell and slams his cock home in increasingly rapid succession, feeling the tingling sensation from the lube run from his cock and through his spine, causing him to grunt and moan lewdly as he announces:”F-fuck! Not gonna last long. Ngh! Your ass is so tight, Raphy. It’s the best!”
Mikey’s thrusts cause Raphael’s body to shake back and forth, Donatello moaning as he clings himself to the muscular turtle’s chest as he enjoys Raph’s thick meaty cock sliding all over his own, both green humanoid cocks slick with their mingled precum. Raphael seems to loosen up as a result of the lube, his mind becoming somewhat cloudy as he now more openly moans around the cock of his stuck-up brother, sucking Leonardo’s juicy helmet for an intense few moments and then deep-throating the whole shaft, showing Leo what he can do!

Mikey utters a loud guttural yell as he slams his hips into Raph’s one last time, his perineum bulging as he pumps jet after jet of hot turtle semen deeply within his brother’s bowels. The smallest of the siblings then collapses on top of Raphael, his hands stroking his muscular brother’s sides in a moment of tenderness before Leo announces:”You go ahead, Donny.”

Donatello slides out from underneath Raphael, thick strands of precum oozing down onto the gym mats as Mikey moves out of the way and takes Donny’s place underneath the bottoming Raph. Raphael stops sucking Leonardo’s cock for a moment as he looks down at the blissful smile on Michelangelo’s lips, eliciting a smile of his own, as he leans down and gives his favourite little brother a kiss:”Good job, lil’ bro.”
As Donny with the purple bandana lines up his own cock and pours some more of the strange lubricant onto it, Leo kneels down so that both Raph and Mikey can suck and lick his trembling erect penis together. Then Raphael groans as he feels the second cock invade his bowels, pushing back into Donatello and actively fucking into his tallest brother. Donny can appreciate the mutual effort and grabs his brothers hips to slam his cock in him in rhythm with Raphael’s dancing ass.

Another minute of no sounds other than wet slurps, slaps, and moaning, as Mikey and Raph french-kiss each other around Leonardo’s dripping cock head and Donatello ruts his brother’s ass like a man possessed. Eventually he moans somewhat quietly, always having been the more discrete one when it comes to cumming, as hot spurts of more incestuous brotherly turtle semen fill Raphael’s anus.

Leonardo steps up and Donny can barely coat his sibling’s cock with the curious lube before it plunges inside the now-somewhat-looser hole. Donatello just sits down indian-style in front of the heads of Michelangelo and Raphael, not interrupting them but simply enjoying watching them kiss and rub their cocks into each other as Leo takes charge at the rear. The turtle with the blue bandana seems to have some conflicting sentiments to work out, slamming his cock into his muscular brother’s ass the hardest of all three, gritting his teeth as he leans forwards and bites Raphael’s shoulder as he breeds his sibling like a beast. Raph grunts, his eyes rolling back in his lustful cloudy haze as he glares at his oldest brother, sensing his challenge of his status as the alpha male of the group. Before anything can happen, though, Mikey has turned Raph’s head back to face him, his sweet smile and amorous eyes disarming the anger in his strongest brother’s heart. They nuzzle their noses together, Mikey pecking kisses all over Raph’s face, their cocks coated in a thick layer of slimy warm precum as they rub together in a massaging motion.

Leonardo utters a loud cry of battle, basically crawling entirely on top of Raphael’s body as he ruts him like a monkey. With one last powerful slam, he thrusts his cock deeply within his brother’s ass and spews forth the last of the three hot loads, their brotherly semen mixing deeply within Raphael’s ass as the strange glowing lube seems to clump it all together. Raphael grunts too, powerful jets of hot sperm coating Mikey’s stomach and cock beneath him, the youngest turtle eagerly pressing himself up into his brother and rubs himself all around to share the warm sticky feeling with his favourite sibling.

When the oldest turtle brother dismounts Raph, some of their combined seed starts to flow from the abused hole, Raphael grunting and forcing his sphincter shut to show his brothers that he can handle their loads. With his bowels churning, full of cum, Raph and his three brothers head to the showers to clean up, Leonardo suddenly noticing something on Raphael’s shell:”Uhm, Raph? What’s this?”
Raphael looks at his brother confused, trying to see the spot but it’s out of his line of sight:”What? What’s wrong?”
Donny and Leo look at the spot and burst out laughing, Mikey grinning from ear to ear as Donatello proclaims:”Apparently ‘Mikey was here!’”
He takes a picture of the words carved into the shell and Michelangelo starts running through their home to escape his brother’s wrath, completely nude, grinning as he’s soon chased by an angry Raphael.
