>"Hah! Told you you didn't stand a chance, loser!" Your sister gloats, breathing only half as labored as yours.
"Yeah, yeah, you win, big whoop," you reply, hands on your knees and panting while you glare up at Rainbow Dash.
>"Damn right big whoop, because that means you're buying the tickets," she shoots back, flicking you on the nose. "So say bye-bye to that allowance of yours. And on the same day you got it, too, that must sting."
"Whatever, I'll get you next time when I get to choose the contest. Picking fifty laps around the yard was cheap and you know it."
>It really was, a soccer star challenging a weight lifter to a footrace was just unfair.
>The some forty pounds of extra muscle you have on the girl doesn't exactly make you aerodynamic.
>"Sure ya will, bro, keep telling yourself that. Now go get your wallet so we can get to the theater. The movie starts in half an hour."
"Fine, but you're gonna have to wait for a bit. I ain't going out covered in sweat, so I'm taking a shower."
>Straightening up and brushing past the smaller girl, you take some immature solace in the fact that the contact almost topples her over.
>"Hey, watch it! And who says you get the shower first? I'm not exactly smelling like lilacs here."
"Not like you do any other time either. And besides, I'm a guy, I'll stink up the whole theater before the previews finish if I go like this."
>"Yeah? Well, I won the race, so I say I get dibs."
"Oh yeah?"
>"Yeah!"
>The two of you stare each other down, a battle of wills transpiring between you.
>Any other guy, and they'd be grovelling at Rainbow Dash's boots by now, but you aren't just some guy.
>You are Anonymous, Rainbow Dash's older brother, and you will not back down.
>When the girl sees this, her eyes narrow.
>You spot her calves tensing, and yours do the same.
>Her advantage, her speed.
>Yours, your head start and wide shoulders.
>If you reach the narrow hall leading to the bathroom first, the shower's as good as yours.
>A bird's shit splatters the ground between you, and it starts.
>Making it across the yard in record time, you swing the door open and attempt to slam it behind you.
>Rainbow checks it into the wall before it latches and tries to dart around you.
>So you of course close line the bitch as is a sibling's right.
>You smirk hearing the air rush out of her lungs upon hitting the ground, but go flying forward when she hooks your ankle with her foot.
>She's up and running past you, but you catch her leg and bring her back down.
>Hoisting her back as you lunge forward, you take the lead again while she yells about carpet burn.
>The hallway is just ahead.
>Victory is yours!
"Haha! Smell ya later, Rainbow Cra-Gah!"
>"You're gonna be the only one smelling around here, meathead, once I lock you out of the bathroom!"
>You try to dislodge Dash from your back, pulling at the arms locked around your neck.
>Damn, you never should have taught her how to perform a proper sleeper hold.
>The betrayal is real.
>Just as spots begin to form at the sides of your vision, you slam backwards, crushing your little sis between you and the wall.
>"Oomph!"
"Get. Off. My. Back. Women!"
>Five more slams dislodges the spider monkey and the shift in weight has you falling to one knee.
>"Fuck, are you trying to break my ribs!?"
"I'm trying to take a shower, so let me!"
>"Never!"
>Once again you're off, your sister and you fighting tooth and nail every step of the way until you reach the threshold of bathroom.
"Ah, Fuck enough! Enough!" you shout from the ground, reaching back to grab Dash and yank her towards your front.
>Some of your hair comes out in her grip.
>"No way! I'm getting the shower, doofus! I beat you here!"
"What? It's a tie and you know it, Rainbow Cunt!"
>"So what? You want to share or something?" she snarks. 
"..."
>"What the fucks with that look?"
"Well..."
>"Oh my God, are you serious right now? Let got, you fucking sicko!"
"Oh, don't flatter yourself! I'm just being logical here!"
>"Yeah, because hopping in the shower with your sixteen year old sister is real logical."
"It kind of is though. Just hear me out!"
>"Okay sure, whatever, just let me go first."
"Only if you promise not to boot me in the face and lock the door on me."
>"Yeah, I promise."
"... Pinkie Promise?"
>"..."
"You fucking cunt, you were going to do it!"
>"Fine, I was, but I Pinkie promise, you happy now!?"
>You let her go in answer and she sits up and away from you, arms crossed as she glares.
>"Okay, I'm listening, now tell me what stupid idea has gotten into that meathead of yours so I can kick you in the face and have my shower already. I don't want to be late for the movie you're still paying for."
"That's just it," you reply, sitting up yourself and pointing a finger. "We've already wasted enough time fighting over the shower, and now we got, what? fifteen, twenty minutes tops to make it?"
"I say we just bite the bullet and both take a shower at the same time so we can at least get to the theater before the movie starts. We'll be missing the previews as it is."
>"Are you seriously suggesting this right now? Do you hear yourself?"
"What's the big deal? We did it before."
>"Yeah, like eight years ago."
"So what? You shower with other people at school. So do I, and there's nothing weird about it then."
>"But those are girls, and not my idiot brother."
"Too bad. I ain't taking you to the movies smelling like this, so that's that."
>"You can't squelch on a bet!"
"Why not? When I won the last bet and you were supposed to take dish duty for a week, you backed out so you could rehearse with that little band of yours."
>"That was different! The fate of the world was riding on us winning against those fish bitches!"
"Sure it was, and a few extra minutes after dinner to clean up would have doomed us all."
>"It might have!"
>At the flat look you give her, she throws her hands up.
>"Okay, fine, I squelched. Nevermind that I saved the world, those dishes were still my responsibility. What do you want, an apology?"
"I want you to get in that shower with me so we can both get clean and still make it to see Scorcher VI Global Meltdown. Tugg Speedman's my shit, Rainbow. I don't want to wait for the blu-ray to see this movie."
>"For fuck's sake, fine. Geez, I want to see the movie too, but I swear you're gay for Speedman."
Completely serious, you answer, "I would have that man's babies, Dash, and then he would carry them to safety through hellfire and glacier ice in a babybjörn."
>"So gay," she says, climbing to her feet with an eye-roll. "At least I don't have to worry about you getting frisky in there."
"Hey. Don't be so sure," you tease. "You are pretty mannish, after all- ooph!"
>Rainbow retracts her leg from your gut with a scowl as you wheeze-laugh from the floor.
>"Yuck it up, big guy. I'm making you buy me an extra large popcorn and soda for that. And I'm not gonna share!"
"Worth it," you whisper to yourself with a smirk, standing up and shutting the door.
>Turning, you see Dash already peeling her sweat-soaked clothes off, throwing the shirt down on the tile with a wet smack.
>It wasn't as bad after the fifty laps, but the race here was a fierce one.
>With all the rolling around you two just did, you both are probably sporting some of the other's sweat.
>"You gonna get undressed, or are you just gonna stare?" Dash snaps, kicking her black shorts off to leave her in nothing but a blue sports bra and panties.
>Despite the comments to the contrary, your sister really didn't look half bad.
>Her athletic lifestyle leaving her toned and svelte, but still with a few curves.
>Her breasts were B-cups at most, but perky, and her hips flared out just enough to be noticeable.
>There's been locker room talk about her that you had to nip in the bud on a couple occasions.
>Not that you care if any of them actually scored with her, but she was your little sis.
>It's an unwritten rule of big brotherhood that you've got to give boys going after your sister a hard time.
>Not as if any of those wimps could handle her.
>Looking at those muscled thighs shift as she shimmies her panties down, she'd probably crush their pelvises.
>"Don't tell me your chickening out? This was your idea."
>Your eyes snap from her pert backside to meet hers.
>She's looking back at you questioningly, but there's the slightest blush on her cheeks.
"Nah, I was just thinking of something, go ahead and start without me," you answer, hoping she doesn't notice the slight bulge in your pants.
>What the fuck, Anon?
>She's your sister.
>Hot sister, sure.
>And probably one of few people who can actually challenge, and beat you in athletic competitions.
>The only girl who'd be able to keep up with you in the sack.
>Wait, whatchu say, Willy?
>You heard me, man, yo sister's smokin'!
>After mentally chastising your dick, you have to wait a bit for it to get the message while Dash hops in the shower and turns the facet.
>Can't join her with half a chub, after all.
>Watching her silhouette behind the curtain as she wets and runs her fingers through her hair doesn't help, so you look at the unsexy toilet instead.
>After thirty seconds, you begin to pull your own clothes off, the smell of B.O. already thick on them.
>Taking a deep breath of steamy air, you slide the curtain back, and step over the side of the tub.
>"took you long enough," Dash states offhandedly, squirting a blob of shampoo in her hand.
"Whatever, just hand me the shower head, will ya," you reply, taking the proffered sprayer as she hands it back.
>The two of you remain silent for a minute as you spray yourself down and she lathers her hair.
>Until she takes a sniff of the air and gives an exaggerated grimace.
>"Phew, you weren't kidding, you stink so bad I can smell you over the soap."
"Could be you, Rainbow Stank," you fire back, spraying her in the back of the head.
>It's meant to be harmless, but she swears.
>"Ah, shit! What the fuck, Anon!?"
"It's just water, stop being a baby."
>"Except that you just rinsed a glob of suds in my eye!" she grits, rubbing her face with one hand while spinning around to punch you with the other.
>The strike hardly fazed you, but the minute, pendulum swing of her breasts does.
>Your penis begins to rise, sending traitorous thoughts to your brain while robbing it of precious blood flow.
>While her eyes are still slammed shut in pain, your hands dart down to cover your growing cock, and the shower head still in your grasp makes painful contact with your junk.
>With a hiss, you shift your weight, and your footing suddenly gives.
>Next thing you know, your feet go flying out from under you, bowling Dash's own out as your ass collides loudly with the tub.
>While you're still registering the pain in your backside, a forearm connects with your face as a weight lands heavily on top of you.
>Groans and the sound of the shower spray striking the curtain is all there is until rainbow speaks.
>"What. The fuck. Anon?"
"It was.. an accident," you answer, attempting to reclaim the breath driven from your lungs.
>Rainbow grunts, trying to push herself up from your stomach, and pinning your manhood down in the process.
>You groan again, this time not exclusively from pain while Dash stares disbelievingly at what she's holding.
>Eyes wide, she throws herself off of you and against the other end of the tub, pointing.
>"What the fuck is that, Anon!?"
"What? I thought you had sex-ed in middle school," you quip as you prop yourself up on your elbows with a hiss.
>"This isn't the time for jokes, smartass! I mean, why is it like.. that!"
>She thrusts her finger forward for punctuation, eyes still glued to your erection as it throbs slightly under the attention.
"What do you want me to say? It happens, okay. it's part of being a guy."
>"I thought it's only supposed to be like that when a guy is, you know, horny."
"Well, you did just sorta surprise me with full frontal..."
>"Oh my God!" covering her chest and face completely burning, she flounders for a second.
>"What was with all that talk about it not being weird, huh, Anon!? You've made it weird!"
"That was before I realized you were hot!"
>Her mouth slams shut as you both stare at each other, your dick standing proud between you.
>The smug bastard.
>"You... think I'm hot?"
>You sigh, running a hand down your face.
"Yeah... like, you've got a hot bod." You point at her. "Still think you're a total bitch, though."
>Some of the tension breaks as she huffs a quick laugh, shoulders relaxing.
>"Not as big a bitch as you," she says, slowly lowering her arms to reveal her chest. "And, I guess I can't blame you for noticing how hot I am. I mean, look at me."
>You groan, throwing your head back and trying not to take her up on her offer.
"Great, now I just went and inflated your ego more. I'm never gonna hear the end of this, am I."
>"Nope," she chirps before her eyes flick over your body, halting on your member.
>"But, ah, hey, if it's any consolation, you're not, you know, bad looking either..."
>You stare at her, expression unreadable until she breaks eye contact, then you pick the sprayer up and blast her in the face.
>"Aah! What the hell!"
"This is weird enough without you complementing me. Starting to worry I fell through a mirror to some bizzaro alternate universe or something."
>She parts the rainbow sheet of hair away from her face to growl at you.
>"Oh, I'm sorry, I should have told the truth. Like how your muscles look like someone stuffed a dead pig full of balloons."
"That's the sis I know and hate."
>"Or how your dick's tiny!"
"Wow, okay, wait up."
>"Yeah, like, I'd need one of Sunset's microscopes just to see it!"
"Dash, you do not want to go down this road."
>She doesn't heed the warning.
>"You're so small, I bet the other guys in the locker room think you're a girl and try to do you up the- H-hey! What's the big idea!?"
>You stand and step over your sister, her knees between your feet and your cock an inch away from her nose.
"Just helping my poor little sister out. Who knew she was so nearsighted, but this should be close enough."
>"Oh, thanks, bro, I got twenty-twenty vision, but now I can actually see your shrivel dick!" she shoots back.
"That so..."
>"Yep, it's the size of a tic tac, so I couldn't see if from across the tub."
>She yelps suddenly when you grab her head and press your tip hard against her cheek.
"Well then, how about I freshen your breath?"
>"Hey! What do you think you're- herk!?" You plunge your cock between her running lips, putting that loud mouth to good use.
>You groan slightly at the slick feeling as your sister fruitlessly tries to push herself off with her hands against your thighs.
>After a few seconds, you slowly, regretfully let off the back of her head, and she instantly starts sputtering and spitting once the dick is out of her mouth, trying to get rid of the taste of pre on her tongue.
>"What the hell, Anon!? You trying to choke me to death!?"
"Hmm? I don't think I've ever heard of someone choking on a tic tac," you answer innocently, getting her to glare up at you.
>"Real funny, you're lucky I didn't bite it off, asshole."
"Oh, we both know you wouldn't do that to your loving big brother," you coo, petting her head. "Besides, you probably liked it too much to try."
>"What are you talking about? Of course I didn't like you raping my mouth!"
"Then why are your thighs rubbing together like a kid trying not to pee themselves?"
>Her legs stop, and she blushes fiercely.
>"Th-that, I mean, i-it's, just, the air, and-and."
"You don't need to lie, Dash, I know you haven't been getting any action," You soothe mockingly.
"It must be hard, with those friends of yours. All knockouts, nines and tens, except for you. Doesn't exactly make you look good by comparison."
"And those two, Sunset and Pinkie, right? They don't exaclty leave scraps, do they? The Pie girl's got a reputation that even the seniors know about, so of course guys don't exactly notice you with such an... experienced girl around."
>"I get noticed plenty," Dash counters lamely, crossing her arms and glaring petulantly down. "There's just no guys around who can handle how awesome I am in bed."
"Really, because I heard Pinkie can get a guy to pop in less than a minute, she's that good. Her nickname's Twinkie Pie because she doesn't stop until she's gotten every last drop of cream a dude has to offer inside of her."
>"Pfft, a minute? I could get a guy to finish in ten seconds flat!"
"Yeah?"
>"Yeah!"
>You slap eight inches of man-meat against her face and say, "Prove it."
>Flinching back, she looks from your member to your skeptical expression, before narrowing her eyes and grabbing your cock roughly at the base.
>"You want proof? Fine, prepared to get your mind blown," is all she says before slamming her mouth down on you.
>You grunt, grimacing as her teach scrape over your head, but she soon improves her technique as you cross your arms and watch your little sister go to work on your member voraciously.
>You're surprised stoking her competitive nature actually worked this well.
>Heck, you're surprised by the whole situation.
>And especially by how turned on you're getting at the sight of your sister polishing your knob.
>It felt like only yesterday that you were carrying her on your shoulders at the town fair.
>Fuck, that thought pushes you even closer to the edge, the image of a younger rainbow Dash overlapping the one between your legs for a second.
>If she weren't working your shaft like it was a butter churning competition, she might have actually managed the ten seconds she gloated.
>But you just passed the minute mark, and seeing her other hand covertly snake between her legs has gotten you eager for more than just a bj.
>You reach down and flick her nose.
>She jerks back, a hand breaking the strand of saliva between her lips and your dick as she rubs her nose.
>"Why'd you do that!? Were to trying to picture Tugg Speedman and it wasn't working?"
"If Tugg Speedman was blowing me, I'd have cum in five seconds. No, I stopped you because you lost."
>"Lost? Lost what?"
"You didn't make me finish in ten seconds flat, so now I get a prize," you say, lowering yourself down.
"But that wasn't a bet!" she retorts sliding back as your hands come to rest on the lip of the tub over her shoulders.
"Close enough for me," you breath huskily, wedging a knee between hers, and working to separate them.
>She doesn't put up much resistance as she watches you wide-eyed.
"Don't worry, Dash, I saw what you were doing, you need this as much as I do. I'll give you what those boys at school are to stupid to give."
>Her breath hitches as your leg comes into contact with her privates, moaning as you touch your lips against her neck.
>The fight leaves her completely as you give a quick bite to her collarbone, before moving lower.
>This was your little sister, after all, and big brothers took care of there little sisters.
>Ano- oh..." she moans as you place her nipple in your mouth, swirling your tongue around it for a moment until her hands reach the top of your head and try to push you down.
>Heh, that's Rainbow Dash for you.
>It's all speed and impatience with her.
>Obliging the girl, you let her force you lower, though still at your pace as you kiss teasingly over her abs.
>With a growl, she pushes harder, and you finally arrive at your destination, prepared to rock your sister's world.
>Until you see your her sex, that is.
>Then you can't stop laughing.
"Bwahaha! You- you shaved your- your pubes-"
>"Wha-? H-hey! what's so funny about that!? It's cool!"
"Sure it is, lighting crotch. Hey, if that's the bolt, do you call these the thunder thighs? Bwaha-oomph!"
>She kicks you in the chest.
>Her legs, strengthened by years of soccer, easily propel you to the other side of the tub, but you can still see her crotch.
>And the rainbow lighting bolt just above it.
"I can't believe you'd shave your pubes in the shape of a lighting bolt. What were you even thinking?" You say, still chuckling.
>"Stupid Pinkie," your sister grumbles, "It works for her, and she said guys thought it was cute."
>As your laughter begins to pick up again, Dash growls and leaps atop you, knocking the wind out of you when she comes down hard to straddle your stomach.
>At first, you think she's going to start pummeling your face, but her hands come to rest on your pecs as she lifts her hips to look between you.
>"Whatever, are we going to do this or not?"
"I don't know, I don't want to get electrocuted," you joke even as your cock twitches in anticipation.
>"Oh, this is gonna be electric all right," she fumed, grabbing your member roughly once more and angling it towards her folds. "Prepared to get the shock of your life, wiseguy."
>Before you can retort with some more witty satire, she plunges herself all the way down in one quick motion, getting you to moan and grab her hips while she hisses.
>She doesn't stop there, however, and immediately begins lifting herself again.
"Wow, Dash, g-give yourself a second to adjust," you try to say, watching her tight pussy slide up your cock.
>There's no blood, at least, though you honestly wonder if she wasn't a virgin, or if she'd simply busted her hymen doing sports or a reckless stunt.
>You don't have time to ask as she slams herself down once more and groans, eyes half-lidded and bottom lip caught between her teeth.
>Sliding up again, you see a small twitch of discomfort flash across Dash's face, and your own sobers in determination.
>Grip tightening on her hips, you halt her as she tries to bring herself down again.
"Enough, Dash, you don't need to hurt yourself."
>"I-I don't know what you're talking about," she answers shakily.
>She tries to force herself down once more, but is again prevented by you, getting her to frown.
Seeking to stem the incoming tirade, you say, "Listen, it's like training, sis, you start out slow and warm up before the intense stuff, so... take it a bit slow." As an after thought, you add, "For me."
>She smirks.
>"Afraid I was gonna make you cum too fast, eh? Fine, I'll go easy on you."
>You smile yourself, loosening your grip and letting your sister move.
>Slower this time, she lowers again, and you both moan as your hips connect.
>She grinds against you for a few of seconds, finally letting herself adjust, before bringing your head to the edge of her entrance and slowly sliding down.
>With each thrust, she begins to pick up speed, her breasts soon bouncing with the rest of her as she lifts a hand to her chest.
>Cupping one of her warm mounds, she works it between her fingers, the sight getting your hips to jerk up slightly.
>She smiles seductively.
>"Mmm, what's wrong, Anon? you aren't saying anything. Don't you want to make a joke? maybe say you aren't loving your little sister's pussy?"
"Mmph... What's that now? Are we having sex? Guess you're so loose I couldn't tell we started."
>"Or maybe you're too small? Even seven years of soccer can't make a girl tight enough to get a grip on your little dick."
"Oh, we're back to that, are we? Guess I didn't pound the lesson into you hard enough the first time," you say huskily, body tensing. "Here, I'll fix that."
>She shrieks as you lunge forward, pinning her beneath you on her back.
>You thrust in hard, her legs wrapping around your hips as her arms snake around your neck.
>She's helpless, half her body propped against the side of the tub and her head curled into your collarbone as you pound into her.
>She's absolutely dripping now, so you don't hesitate to give her the proper Anon-treatment.
>You sink into her heat again and again, feeling her walls convulse around your manhood as her moans turn into screams.
"Guess I'm not so small, after all," you growl, forcing yourself through the tightening grip as your sister orgasms, not slowing down a bit. "Tell me, how do you like your brother's dick?"
>"I-I love it! Harder, Anon!" she squeals toes curling as she tries to move her hips to meet yours.
>Folded up as she is, she doesn't manage much, but you won't deny your hot little sister more pleasure if she wants it.
>You bite and suck at her neck while bringing a hand to her chest, squeezing the a warm breast and pinching the erect nipple.
>The added attention sends her over again, and she screams.
>"Yes! Yes! Fuck me, Anon! More!"
>Already at your limit, you nonetheless oblige, giving a hundred-and-ten percent like your couch always preaches.
>The hand still on her hip digs angry marks into her skin while hers do the same across your back.
>The air is filled with moans, slaps, and screams as the two of you lose yourself in each other.
>No girl has ever been this tight.
>This willing to let you go all out without demanding you slow down and be gentle.
>Your sister was ruining you for other girls.
>But you'd be damned if you wouldn't do the same to her.
>No other man would ever pleasure her like you.
>Not like you'd let them.
>Dash is your sister, no one elses.
>It's this thought that begins to overtake you as you finally near your own climax.
>You should seed her.
>Make her carry your child.
>Then everyone would know who this beautiful girl belonged to.
>You're cock begins to twitch wildly as your balls constrict.
>With a roar of both pleasure and turmoil, you plunge in one last time, feeling the cum boil up your shaft, before pulling back.
>The first thick rope of pearly-white cum splatters against Dash's folds just as you exit, and the rest flies to streak against her stomach and chest.
>Some even lands on your own chest and the hand fondling Rainbow's breast.
>You don't care though as you bring your forehead to rest against Dash's.
>You both pant, eyes closed as the sprayer behind you sends water straight up to the ceiling.
>It pools and drips down o the two of you like a warm, gentle rain, rinsing away the sweat and fluids of your passion.
>Finally, her lids flicker open and she stares at you with those magenta orbs.
>As you open your own eyes and stare back, you can't believe you never noticed how beautiful they were.
>She breaks eye contact and looks between you.
>"Huff, huff, you... pulled out?"
"Yeah," you answer tiredly, still not getting off of her. "Figured you didn't want to explain to Mom and Dad how you got pregnant with your brother's kid. I know I don't want to tell them."
>"Heh, yeah, I would have to spend my allowance on Plan B, then we'd both be broke."
>You blink a few times, then groan. "Ah shit, the movie. How long have we been in here?"
>She pushes you back as she sits up.
>"Crap, you're right, it's definitely been more then twenty minutes." She sends a glare your way, but there's no real anger behind it. "I thought taking a shower together was supposed to save time, idiot."
>You chuckle and shrug.
"What can I say? The plan didn't account for how sexy you are."
>She blushes and calls you an idiot again, punctuating the statement with a punch to your shoulder.
>"Whatever, we'll just have to go to the midnight showing instead."
>You raise a brow.
"But it's a school night, the folks would never let us go."
>"Really, Anon, you're talking about not breaking the rules now?" she asks skeptically. "...After we just fucked?"
"Point taken," you acknowledge. "So what? we sneaking out?"
>"You're damn right we are. This is the last night it's playing at the theater, and I'm not letting you squelch on the deal. I still want my extra large popcorn and soda."
>You laugh as you stand, reaching down to help her up.
>As her legs come under her, she stumbles into your chest.
"Wow, you alright, Dash?" you ask in concern.
>"Yeah, legs are just a little numb," she answers, before realizing what she said and looking at you wide-eyed. "Don't you even-"
"Really?" you say, a shit-eating grin on your face. "Wow, I didn't realize I was that good. Well, okay, I did, but with all the bragging you did, I figured I was going to be the one who couldn't walk straight."
>"Oh shut up," she says, slapping your chest. "This is just great, I went and inflated your ego. I'm never going to hear the end of this, am I?"
"Nope," you answer cheekily.
>She sighs and pushes off of you, a little wobbly, but steady enough to stand as she moves to grab the sprayer.
>"Let's just get cleaned off already before the hot water runs out," she says, before jolting a little as one hand grabs the shower head from hers and the other snakes around her waist.
"Sure thing, sis, but how 'bout you let me do that? I did make the mess, after all."
>You start to spray away the cum on her chest, slowly lowering the stream as well as your other hand until both reach between her legs.
>"A-anon-"
"Shh, don't worry, Rainbow Dash, big brother will get you squeaky clean..."
>The bathroom was once again filled with moans, and the two of you didn't leave until the water ran cold.
>You had plenty of time before the movie started, and a couple hours with the house to yourselves until your parents got off work.
