Work Text:
“Really gotta go,” Mark whines loudly in the back seat.
Johnny finds it so annoying. His little brother must have the bladder of a squirrel or something because this is the second time they've had to stop in barely an hour.
There's no rest stop for miles. They're stopped on the side of the highway, practically in the middle of nowhere.
“The side of the road?” Mark asks, squirming uncomfortably.
“I'm sorry, sweetheart,” their mom says. “It's the best we can do for now. The nearest stop isn't very close.”
Mark whines but he really can't hold it any longer it seems because he jumps out of the car and runs straight for the trees.
“Wait!” Their mom yells. But Mark is already halfway down the hill and past the tree line.
She's about to chase after him but suddenly she gets a phone call.
“Caller ID says it's from work. I have to take this. Can you keep an eye on your brother please?” she says.
Johnny's face scrunched up. Gross. Why him?
“No way, I'm not watching him piss.”
“I'm not saying watch him do that. I'm saying just stay near him. I don't want him getting lost or something. He's only ten years old. Now go!”
Johnny wants to protest but she's already answering the phone with her high-pitch business friendly voice. He's lost the battle
He groans and climbs out of the car. He travels down the hill in frustrated stomps. He feels like he's being childish himself in a way. But really, why should he have to be the one to stand near his brother for this? When he was ten, he wouldn't have done something stupid like wonder off in the woods. Their car is just up the hill anyway. Why would Mark get lost? Whatever. His mom just likes to baby Mark too much.
“Hey, please tell me you're done already,” Johnny calls when he reaches the bottom of the hill.
He hears Mark shuffling around on the other side of a tree trunk. Johnny keeps his distance.
“Almost. But don't look!” Mark says.
“Trust me, I wasn't planning on it.”
Johnny tries to focus on something else besides the muffled sound of Mark's piss hitting the ground. Anything. Like the rustling of the oak branches or the bird pecking at the ground in search of insects. Or the faintly distant sound of cars zooming by on the highway. After what feels like decently too long, and after a long stretch of silence, Johnny turns around.
“Dude, are doing a number two or something. Hurry up,” Johnny says.
“I'm not!” Mark protests. But then he goes silent again.
“So what's taking so long?”
“Um… Johnny?”
“What?” Johnny groans.
“I'm done peeing, but uh… I don't have anything to wipe myself with.”
Johnny rolls his eyes. Mark is always making things complicated for no reason.
“Just use a leaf or something, duh.”
More silence.
“Seriously?” Johnny says. “Are you just planning to stand there with piss on yourself forever.”
“Johnny” Mark whines. “I can't use these leaves. I think they're poisonous.”
“Why would they be poisonous, Mark?”
Johnny is halfway ready to just leave Mark here and head back to the car. This is getting ridiculous.
“I learned about these leaves in school. They're called poison ivy,” Mark says.
“You're telling me every single leaf around you is poison ivy?” Johnny asks, not even attempting to hide the annoyance in his voice.
“Yes. Seriously, dude!” Mark says. “None of them look safe. I don't know what to do.”
Johnny sighs and decides he's finally had enough. He steps around the tree trunk and finds Mark crouched with his shorts to his knees.
“Hey! Privacy?” Mark says quickly trying to cover himself.
“I don't want to see you either, but you're taking too damn long.”
Mark puts his back to the tree and awkwardly tries to cover his naked privates with one hand while keeping his shorts from falling to the ground with the other. Johnny rolls his eyes and shakes his head.
“You're probably just not looking good enough. Let me take a look,” Johnny says.
He surveys the area. Ivy grows on the branches of all the surrounding bushes. He's no professional in plant life, but he does have to admit these leaves look suspicious. Every single one of them seems to have the three-leaf count pattern of poison ivy that he's vaguely familiar with. Maybe Mark was right.
He tracks further into the trees trying to find any leaf that looks safe. But he's coming up at a loss and the further he travels into the trees, the thicker the canopy above becomes, making it darker and harder to see the leaves clearly. They've already wasted too much time. He does the smart thing and turns back towards the highway before he gets too deep into the woods. They're going to have to solve this problem another way.
“Did you find anything?” Mark asks when Johnny returns. His shorts are pulled up to his thighs now.
“Nope. Sorry, I think you might be right. We've been unlucky enough to stop near a bunch of poison oak.”
Mark whines and squirms in place. “What should I do?” he asks.
Johnny looks around in a last-ditch effort to find something Mark can wipe with. But he comes with nothing.
“I think you're just gonna have to go without wiping,” he says.
“No! I can't do that. It's nasty,” Mark says. “I might get…” he lowers his voice as if anyone could possibly be out here to hear them. “I might get a rash again.”
Johnny sighs. This is so unnecessarily frustrating. Mark is prone to rashes. Over literally anything. Dust rashes, heat rashes, you name it and Mark has probably gotten it. Just last summer, Mark had to come home early from camp because he got a bad rash from his underwear not being washed with sensitive grade detergent.
“So what do you expect me to do here exactly?” Johnny asks.
Mark shrugs. “I dunno, you're the big brother.”
To Johnny's chagrin, Mark is right. He is the big brother so he has to figure something out quickly or else their mom's gonna freak out and blame him. If Johnny lets his brother get a rash, or lord forbid crotch poisoning from the three-leaved plants, she'd probably kill him.
He racks his brain for an idea. Anything. His mind flips through a bunch of possibilities. Then, like a sudden spark, a thought comes to his mind. A thought so crazy that it almost knocks the wind from his chest. A thought so dirty, he has to mentally slap himself. But it's all he can think of as a solution to their problem.
His eyes flicker to Mark's body where he keeps his hand over his privates. Then up to Mark's eyes that are full of distress and embarrassment.
Johnny swallows thickly. “Dude, I have an idea but you're gonna have to promise not to tell anyone about this.”
Mark frowns in confusion. “What is it?”
Johnny takes a deep breath and steps closer to Mark. He crouches down to Mark's pelvis line and attempts to move the boy's hand aside.
“What are you doing?” Mark hisses, quickly swatting Johnny's hand away.
“I can clean you,” Johnny says. “But you have to promise not to tell anyone.”
Mark gulps. “How?”
“First, take your shorts off.”
“What?”
“Dude, just follow what I say,” Johnny demands, on his last leg of patience.
Mark hesitantly drops his shorts and kicks them aside. “Now what?”
“Okay, now spread your legs for me. Try to keep your balance.”
“Um… okay,” Mark says nervously.
He finally moves his hand out of the way completely, exposing his bare privates to his older brother. Directly in front of Johnny's eyes is a part of Mark that he hasn't seen in a while, not since Mark had gotten old enough to stop needing help taking baths. Johnny's pulse pounds loudly in his ears. He's looking directly at his ten year old brother's cunt.
He doesn't let himself overthink anymore. It's already gross enough without the guilt. He lifts one of Mark's legs up and hooks it over his shoulder to help spread his cunt more easily. Mark gasps at the maneuver and quickly grabs onto Johnny so that he doesn't fall over. He uses his other hand to maintain balance on the tree trunk.
“Johnny, what are yo- oh!”
Johnny moves in, gently licking through Mark's little folds, tasting the bitter and salty taste of urine on his tongue. Mark's fingers tighten on Johnny's shoulder. Johnny makes sure to clean him as much as possible, dipping his tongue all the way down to Mark's fluttering entrance and all the way back up to the hood of his small clit.
Mark moans at the feeling, innocent and confused. This obviously must be a new sensation to him. Johnny tries not to dwell too much on the thought that he's the first person to ever have his mouth on Mark's cunt. He focuses on his mission, getting Mark clean.
He uses his fingers to spread Mark's lips further, lapping up more of the bitter piss. He can taste slick starting to leak from Mark's innocent hole too and it makes him feel just a bit more nauseous than he's already been feeling since this sick idea popped into his mind.
“Johnny,” Mark whines, instinctively bucking his hips forward, chasing a feeling he probably doesn't understand.
“Keep down, okay?” Johnny whispers against his cunt.
Mark nods obediently, eyes misty and cheeks flushed red.
“It feels… weird,” Mark says.
Johnny's tongue moves in quick laps, sliding between Mark's folds and up to his clit again. He can feel the little bud hardening with each swipe. Mark's breathing grows quicker and more ragged as Johnny closes his lips and sucks at the sensitive skin. Johnny can tell he's trying his best to keep his voice down.
He grips Mark's thigh and moves his leg out further, to make sure he's fully exposed. He licks with more intensity down his cunt, taking away the final remnants of piss. Fresh slick is pooling on his tongue and he's trying his best not to swallow too much of it, mentally attempting to save himself some form of dignity.
Mark moans when Johnny's tongue dips slightly into his hole, hips rolling to chase the pleasure. But Johnny doesn't keep his tongue there, he slides back up his slit again and sucks on his clit.
“Oh,” Mark shuts his eyes tightly. “Johnny, wait I think- I think I'm gonna pee again,” Mark gasps.
Johnny releases Mark's clit from between his lips and licks long hot swipes over his folds, lapping up the final taste of piss until he's left with just saliva and slick.
Mark's cheeks are red and sweat drips from his forehead and neck. Johnny feels his stomach twist at the sight of him.
“Ahh, I'm- sorry. I'm peeing,” Mark gasps.
His hips stutter, snapping forward and back on their own like a muscle spasm. His fingers clutch painfully at Johnny's shoulder. Johnny can feel it on his tongue, the release of Mark's first orgasm. An orgasm that Mark thinks is piss because he's far too young to know what an orgasm even is.
Johnny quickly cleans the slick too, licking it away and letting it dribble from his mouth to the soil below them. Once he's done, he releases Mark's thigh from his shoulder, letting it drop back down to the ground. Mark almost falls over, knees trembling from the sensation of a post-orgasmic high. Johnny quickly stands to catch him.
“Careful now,” he says, voice sounding hoarse in his own ears.
He coughs and clears his throat. Mark is still clutching onto him, gripping tight to his t-shirt. His flushed cheeks are wet with tears. Johnny lets out a shuddered breath and steps back slowly, unhooking himself from Mark's grasp.
“Um,” he clears his throat again. “You're clean now. You can… you can put your shorts back on.”
Mark blinks a few times and nods.
“Okay,” he whispers.
“Meet me on the hill,” Johnny says.
He quickly turns away to give his brother some privacy to get dressed. Whatever privacy means anymore. He feels lightheaded. What had he just done? The sounds of the passing cars zooming by on the highway suddenly feel like the loud rolls of thunder before a horrible storm.
A few minutes later, Mark joins him as he tracks back up the hill to their car. They don't speak.
“Hey, there you two are,” their mom says as she sees them getting closer. “I was just about to come looking for you. Everything alright?”
Mark climbs into the backseat of the SUV wordlessly. Their mom gives a strange look then turns to Johnny.
“Johnny?” she asks. “You two okay?”
“Never better,” Johnny croaks.
