Blossom 
Leonardo resembles a flower, all green and red and black, petals slowly unfolding as he spreads his legs and arms. Fragile, vulnerable, impossibly soft to the touch. And his sweet scent, which grows sweeter still as his breath quickens into arousal.
Saki knows that Yoshi would never have appreciated this beauty. Would have trampled it into the mud and dirt, left it to the wither in the dark. Saki considers that a far greater crime than anything he could be accused of as he pulls Leonardo close and sets about pollinating him, murmuring gentle words like a soft summer breeze.
 
Sweat 
“You’re so damp,” Leo murmurs after a workout, tracing his fingers across his master’s bare shoulders as the clothes slip away. His body produces moisture, but never quite like this.
Trying to be casual, to be confident (that’s how you finally make this feel normal, right?) he laps at a glistening droplet. Master Shredder stiffens and rounds on Leo with a playful growl, pinning him against the shower wall and closing the curtain behind them (Leo’s heart skitters, but it’s okay).
“Would you like to clean me off?” he asks with a wicked grin, and Leo does
(he really does).
 
Gaze 
The boy looks so very beautiful like this, still slick with blood from the battle, but red-faced and trembling like the virgin he was not so long ago. He straddles Saki’s lap in the limousine’s backseat, mouth pressed shut, and Saki decides not to tell him that the way the car’s reinforced the driver probably wouldn’t hear him if Leonardo screamed.
The ordinary shadows of this ordinary world ripple behind dark glass, and Saki wants to break it suddenly, let the fools see their true masters, see what they cannot possess.
Soon, he thinks, and sets about making Leonardo weep.
 
Tongue 
Leo’s still sore from his first cleansing as he lowers himself onto his knees and elbows, letting his master’s tongue slip inside him. It’s much softer and more flexible than a cock, but just as hungry, just as warm. 
Soon enough he’s a blushing, trembling mess, gasping his Master’s name as he unabashedly wriggles his hips. Leo can smell how turned on Master Shredder is at the sight and that just makes it hotter.
He comes without being touched and collapses, sticky and trembling. Master Shredder generously gives him a few minutes to recover before Leo serves his still-hard cock.
 
Sweet 
Saki savors the way Leonardo’s innocence melts on the tongue like spun sugar, relishing every gasp, every whimper. He plants kisses on his boy’s flaming red cheeks, his rapid pulse, his fluttering eyelids, lapping up every trace of his desire and fear.
He even lowers himself to put Leonardo’s cock in his mouth, savoring his little cry of shock, the way he lamely stutters how Saki doesn’t have to. When Leonardo comes Saki savors the taste of a victory, a battle his chunin didn’t even know was being fought. He pulls Leonardo into a kiss, letting him taste it, too.
 
Give 
Master Shredder has given him so much, more than Leo can ever repay. But he still wants to give as much as he can anyway–his sword, his loyalty, his support, and, if that is what Shredder wants, his body.
So he unhesitatingly offers himself on his knees, his front, his back, whatever his master requires. And it…hurts, a little, to see Master Shredder smirking even as he takes his cock out. To hear him use words like needy and whore and eager , to see him dole out softness as he pleases.
He doesn’t mean it, of course. Leo knows that.
 
Hand 
His hand brushes over Leonardo’s hip, his thigh, makes its way into his lap at meals and toys with his mask tails in a way that’s just the wrong side of fatherly. If he’s feeling particularly daring Saki will let himself toy with Leonardo’s tail, his ass, even his crotch, regarding anyone who dares look at them with cool eyes that promise death.
Leonardo always stiffens and blushes at the touch, unwilling to move away even as he radiates discomfort. Saki just gives him a reassuring smile, already imagining what they’ll be able to do when they have real privacy.
 
Compromise 
Mistress Kitsune usually picks and discards her own companions from the Foot ranks, but sometimes she calls Saki to her bed, and Leo usually comes along for the ride. “A compromise,” Master Shredder will say, not explaining more. Leo doesn’t press, just obediently offers himself up their hunger, as they deserve.
“Nnn,” Mistress Kitsune groans, nails scratching on Leo’s shoulders as he lowers his head between her legs. Master Shredder lets out a grunt from behind him, fingers digging into Leo’s hips as he gives another vicious thrust. Leo knows he’ll be black and blue under his armor come morning.
 
Chocolate 
Sometimes it amuses Saki to play the role of indulgent papa, to cradle Leonardo on his lap like a child or a puppy and offer him the treats Yoshi was never able to provide. He feeds Leonardo pieces of nama chocolate by hand, a special treat for good hard work, for a city crumbling at their feet.
“Clean my fingers,” Saki whispers, and Leonardo does as he’s told, lapping and sucking at Saki’s hand like the obedient little slut he was born to be. Saki’s cock swells, and he knows he’ll have to feed Leonardo’s other hole something even sweeter.
 
Deep 
He’s on his back, legs spread, holding himself upon. Master Shredder’s got one hand on his own cock and the other is inside Leo, pushing deep enough to grab Leo’s heart and crush it before it can beat itself to a stop.
The Shredder has killed so many people with the fist buried inside him. He could kill Leo, too, easy as breathing or wanting. He punches a little bit deeper and Leo’s breath stutters.
Leo trusts his master more than anyone, but he’s terrified. He screws his mouth painfully tight, trying to bury his screams before they ruin everything.
 
Shiver 
Leonardo can’t quite look at him the first time, can’t do anything except tremble as Saki drags a finger along his more sensitive scutes.
“Tell me, chunin,” Saki asks, resting a hand on Leonardo’s bare stomach. “Are you scared?” His other hand tightens on the boy’s thigh. “Be honest.”
Leonardo swallows hard. “I don’t want to be,” he admits brokenly.
“Then don’t,” Saki says, grinding his fingers up into that tempting little slit. Leonardo’s knees buckle with a muffled whine, but Sat pulls him close, holds him up.
“Just trust me,” he whispers. “That’s all there is to it, love.”
 
Melt 
Leo comes home dripping red and white, caught in a storm on the way home from a successful mission. Master Shredder has him strip down and builds a roaring fire, the light caressing his scales like gentle fingers.
His master decides it’s not enough, decides to run his hands over Leo’s body and pepper him with kisses that leaves him flushed in a way that has nothing to do with fire. Puddles of meltwater grow around their feet as Master Shredder’s cock slips inside, filling Leo with its own kind of blazing heat. Leo breathes deep as they dissolve together.
 
Smooth 
For all the battles he’s fought, Leonardo simply hasn’t lived enough to match Saki’s level of scars. They play games together, counting each other’s marks, and Saki always wins. “Soon,” he tells Leonardo cheekily, and the boy huffs, rolling his eyes.
Some of Leonardo’s scars are ones Saki left, and he wonders what story Leonardo would tell if asked about them. Perhaps his mind, rubbed smoother than even his skin in so many pieces, is even able to process those in particular. All he’d be able to see was Saki’s hand on his skin, tracing a patch of untouched flesh.
 
Tingle 
The tingles, the whispers, the little buzzes of anxiety, all disappear when he’s with his master. Bruising kisses slurp up Leo’s bad dreams, drinking down memories of haunted gardens and blood-soaked fields, of colorful masks sucked into the same brownish red.
It’s in the sticky, aching aftermath, when Master Shredder’s arms clutch Leo to the point of strangulations, that the feelings come back. A wrongness that seems to grow stronger the farther they go into this relationship, no matter how many barriers they break down together.
Leo buries his face in Saki’s hair, telling himself he’ll be able to hide.
 
Button 
He pulls Leonardo close and it’s as if some kind of trigger has been flipped, the boy’s eyes going glassy with need as his legs open, head tilting back to accept Saki’s kisses.
Saki could slap him, kick him, spit on him, and Leonardo wouldn’t fight it, just bow his head and accept what he’d automatically assume is a well-deserved punishment. Saki knows because he’s tried it before, although he usually prefers to be gentle. He can be kind while celebrating a triumph (sometimes).
“I love you,” he tells his chunin, and in his own way he really means it.
