It’s another sunset, the blues are slowly turning to dusty yellows and reds and reflecting off the vast desert. It’s just like every other day, Shiro and Keith racing in the desert and stopping in the middle of nowhere to catch up and calm their high. It should be just like every other day, except Keith can tell somethings wrong.

Their rides are everything Keith looks forward to, he’ll take anything the garrison and any of the bratty kids throw at him if it means he’ll be able to spend some time with Shiro. So it’s very obvious to him that something’s different about today, something’s different about Shiro. The very man clouding his thoughts is leaning against his bike, you could practically hear the cogs whirring in that handsome head of his as he stares off into the dusk. His arms are folded, legs shifting weight every so often. The adrenaline is still rushing fast in their veins after their race, where Keith almost managed to beat Shiro. It was obvious Shiro was distracted, and Keith felt like he knew why.

Adam’s been gone on a mission for a while now, ever since him and Shiro became instructors, less mission opportunities have come their way. So when they're separated, it hits hard. In more ways than innocently missing their company.

Keith doesn't want this to get in between their friendship. What Adam does shouldn't be distracting Shiro like this, distracting Shiro from him. Like any good friend would do, Keith wants to help. “Hey, is everything alri-”

And suddenly he’s off balance and falling after carelessly tripping on a rock. The last thing he sees before impact is Shiro rushing to break his fall.

When he gets back to his senses, Keith realises he’s pressed up flat against Shiro who burdened their fall. Immediately, he tries to sit up, legs barely able to straddle the width of Shiro’s hips. “S-Sorry, I-” He tries to apologise, his mouth cutting him off the second he feels something perk up below him. Keith blinks and focuses his gaze directly at Shiro, spotting the older man sporting a startled face fully flushed red.

Before Keith can open his mouth again, Shiro scrambles out from under him. He sits up on his own, trying to hide from behind his legs. Keith isn't stupid, he knows when someone is aroused, when they're not so subtly hiding a boner in public (that James guy was always the worst at it).

Keith doesn’t know what Shiro sees in him, he’s a runt for a kid who’s supposedly 15.. He’s nothing like Adam, he’s nearly half his height and weight and one of the latest bloomers in his class. And yet here he is, sitting in front of Shiro fully knowing well he’s made him aroused. Keith doesn’t know what Shiro sees in him, but Shiro’s the person who taught him believe in himself. And he thinks that maybe this could be one of those situations too, even if it wasn’t intentional.

“If you want… I could take care of that for you.”

It's time Shiro finally realised the extent of Keith’s ability to do anything for him. Anything.

“What are you saying, you can't-”

“I’m not as innocent as you think, Shiro. I can tell you’re pent up.” Keith interrupts, slowly shuffling his way closer to him. It's not the first time he’s blown someone despite his age, certainly won't be the last either.

“That’s not the problem-” Shiro starts again, only to be cut off by Keith who takes a knee in both hands and forces Shiro’s legs apart. “K-Keith!” He yells, completely ignored by the younger man who’s eyeing the bulge strained against those stupid pants far too tight for garrison regulation.

He can feel Shiro try to stand up, but Keith acts quick and leaps to pin him to the side of his hoverbike, cornering him. “Let me do this for you. I promise it won’t be that bad, you can even imagine I’m Adam, if you want.” Keith says, trying to ease Shiro’s thoughts.

Before Shiro can respond, Keith takes the next step for both of them and moves fast to work open Shiro’s belt. His hands are quick, he’s been through this same process before, though he’s never been half as excited and willing as now. Typical, Shiro was always showing him new experiences. Without hesitating, Keith forces Shiro’s pants down far enough that he can comfortably rest a hand inside, fondling Shiro’s cock inside. He swallows as he feels it harden in his grip, he hopes his amateur level skill at this kind of stuff is good enough.

He turns his gaze back at Shiro who’s flushed red again, eyes shut closed and breathing heavy through his nose. “K-Keith, please… You can’t.” Shiro pleads, though he makes no move and is trembling in his spot on the ground. He’s strong, far stronger than the tiny figure before him but Keith knows Shiro, bless his heart, would never do anything to reject Keith. The boy fondles Shiro, massaging through his briefs and feels his own face start to heat up. Shiro’s always been so good to him, it’s his turn to return the favor. He’ll prove himself to Shiro again, just like always.

Keith gulps once Shiro’s dick is pulled out from his briefs, never dealing with one of this size. The ones from the orphanage couldn’t even compare, shrimps belonging to brats he’ll never see again. But the one in his hands belongs to Shiro, his Shiro who, despite his words, is waiting for Keith to act. With a deep breath, Keith goes down and sucks on the head. His mouth is small, just like the rest of him, but he’ll be damned if that’ll keep him from trying his best to please.

Shiro is a dead fish below him, trembling but unmoving, stifling any sounds or reactions as best as he can in hopes to discourage Keith. This only works to want to make him try harder, he should know how much of a shitstarter his mentee is by now. Keith begins to lower himself down Shiro’s hardening cock, he can feel it fill his mouth and begin to stretch out his throat. He gags a little, drawing back only to go back to continue pushing the boundaries all over again. He feels Shiro try to pull back but pulls him closer by his hips, swirling his tongue and ignoring Shiro’s pleas that are cut off in an attempt to hide his moans and grunts.

Even through the prickling tears forming, Keith does his best to never take his eyes off Shiro. It's a challenge but he’s intent on watching and learning any indication of what he enjoys. Keith is by no means experienced, but he can see Shiro’s starting to break under him, panting and grasping at any composure he has left. Keith wonders if he really is thinking about Adam, it leaves him bitter. Adam isn’t here, he’s the one who’s left Shiro this distracted in the first place. Keith’s doing Shiro a favor, he’ll suck the thoughts of Adam right out of him until it’s just them, the way it should be. He feels more confident now, knowing he has something different, something more than his adult partner could ever give him.

He speeds up his pace and wraps his lips tight and tries to take in more with each movement. Shiro moans loudly, bucking his hips and making his dick hit the back of his throat. This time Keith does choke, coughing around Shiro as he feels the older man grip at his hair and drag him off as Keith pants and clear his throat. “Keith, stop- This isn’t your problem. We can’t.” Shiro pleas, breathing heavy and flushed red. Once he composes himself, Keith swallows and looks Shiro directly in the eye.

“Nobody needs to know, Shiro. I need this as much as you, trust me.” Keith counters, noticing the  way his body tells the truth far better than his words. “Just relax, you’ll thank me later, trust me.” He smirks, steeling himself as he goes down on Shiro once more. He’s met with less resistance this time around, hearing Shiro breathe out in a sigh of relief or reluctant acceptance. Keith’s glad to see Shiro looking at him now, eyes lidded and dark despite the disappointment evident in his face most likely projected towards himself rather than Keith. The younger eagerly starts swallowing, easy as Shiro’s dick is coated and hot with Keith’s saliva. Taking a hand, he starts to pump at the base of the shaft he can’t reach with his mouth and sees Shiro move his own hand to muffle another moan he can’t control. Keith smiles around the cock in his mouth, pleased to see he’s getting somewhere, moaning in return and glad to feel Shiro’s dick twitch when he does so.

Soon enough, the salty taste of precum lies on Keith’s tongue. “K-Keith, I’m-” Shiro starts, Keith cutting him off by sucking on him harder as a groan is forced out from him. It’s lucky they’re in the middle of the desert, the sounds loud and shameless as Keith swallows faster and harder to get Shiro off. Shiro’s reduced to a mess beneath him, a hand gripping Keith’s hair, hips unable to control bucking into Keith’s throat, and reciting Keith’s name like a mantra. Keith will give Shiro another distraction, another way to relieve himself without his boyfriend. He’ll keep him relaxed, happy, focused.

“Keith... Keith, Keith, stop! I can’t hold off anymore- I’m-” Shiro exclaims, trying to pull Keith off for a second time only for the younger to hold his ground, unrelenting. With a cry, Shiro cums hard before he realises, slamming his head back on the hoverbike, grunting through his orgasm as Keith attempts to swallow everything given to him. As confident as he was, Keith wasn’t ready for the heavy load, struggling to swallow it all down, struggling not to let his gag reflex get the best of him.

It takes a while for Shiro to come back to his senses, chest heaving as he blinks back to reality. He feels the heat of Keith’s mouth slide off his softening cock and whips his head to look back at Keith. Keith, who has a face nearly drenched in tears and sweat, drool on his lips, and a mouth full of cum, almost comical if it wasn’t for the fact that the sight was undeniably wrong given the context. Keith can’t handle it in his mouth any longer, moving hands from Shiro’s lap and cupping them in front of his mouth. Dribbling from his mouth is Shiro’s cum, hot and thick as it falls into Keith’s hands. Keith manages to surprise him one last time, looking Shiro in the eye and smirking at him as he takes his hands and drinks eagerly. Shiro groans, half in arousal, half aghast, his dick twitching as he watches Keith’s down all of it, licking his hands of the residue afterwards.

Keith has the nerve to smile at him once he’s done, shuffling over to sit next to Shiro, bulge in his own pants evident. He’s so small, sitting next to Shiro like this. So small and entirely too smug. Shiro can’t do anything but sigh and plummet from the high Keith just gave him.

“I wasn’t that bad, was I?” Keith asks, trying to act smart even though Shiro knows he’s genuinely concerned about it. He’s trapped in a minefield, any answer he gives will ultimately destroy him in the end.

“Of course you werent, i-it was amazing,” Shiro answers before he can stop himself. He could never say anything that would leave Keith dejected, never.

While is mentally kicking himself, Keith beams, his young face smiling ear to ear. “Good! And even if you're lying, I’ll only ever get better with more practice.” Keith proclaims, resting his head and laughing on Shiro’s shoulder.

Adam cannot come home soon enough.
