Hot Summer Job/Shock your sister back to life
You're only getting increasingly nervous poking and prodding at your sister, even if it's scratching some increasingly prevalent itch inside you. But you don't want to cross a line and she isn't likely to stop playing dead any time soon. Your sis does get carried away sometimes. You'll need to snap her out of this.
"No, wait! I see signs of life! Defib! Clear!"
You dive down with both hands and find your sister's nipples. A hard pinch and a twist is all it takes to jolt Bree from the brink of death.
"Ahh! Owwww..." whines your sibling. She rubs at the exposed half of her chest, soothing her dainty nip. You couldn't feel if you had a good grip on the swimsuit side, but with bare flesh available to you it was easy to sink in at least one solid bullseye nurple. "What was that for?"
"It's your turn. Two minutes, remember?"
Bree sits up, closing her legs and cupping her breast. "Okay." She continues to sit, not looking at anything in particular. Maybe you pinched her right out of her good mood.
Impatience arrives. You kick at your sister with your foot. "So? Don't you want to dare me?"
"I guess. I don't know what to do though."
"It's easy. Just think of something."
"But it's not. I... All I can think about is my swimsuit..." Bree slips her free hand down between her legs, exploring her newly crotchless one-piece. Although it's probably more of a 'half' piece now.
"It's just a swimsuit. It's not a big deal," even though it kind of is. "But... well, if you want to, you can get revenge."
Bree grins looking down at the floor. "But that'd be mean, wouldn't it?"
"A dare is a dare," you stress. "I know how it works."
Your sis glances up at you playfully then hones in on your bottoms. "Okay, I know!"
"...yes?" you prod.
"I dare you to take off your shorts!"
"Aw, man," you quickly bemoan, but just as quickly comply. You slip out of your bottoms with little effort or fanfare. You're still wearing your boxer briefs, so despite the act of stripping out of a layer of clothing, you're no worse off than a moment ago. That's technically what she asked; just your shorts. But you wonder if she expected more. You stand proud, wearing your underwear and her bikini top, awaiting your sister's judgement.
"Your... crotch is really big," notes Bree, staring at the bulge in your underpants. You're sporting quite the semi to be sure - grabbing your sister's bare pussy was a big help with that - but it wasn't nearly as noticeable through your shorts. You stifle the urge to thank your sis for the compliment.
"I'm almost naked now," you voice with both fabricated frustration and suggestive undertones.
"Well I'm even more naked, so mm!" retorts Bree, sticking out her tongue.
"That's a lot of tongue for a little girl." That was less a quip than a strange observation, but it does offer an inspirational spark. "Speaking of, it's my turn again. This is how simple a good date can be. I dare you to lick my bellybutton for 10 seconds."
"Your belly button?!" recoils Bree in horror. "That's gross!"
"Really? I mean, if you'd rather lick my butt, that's cool."
"Ew! No! But... oh fine!" Your sister sighs with exasperation.
You inch down the back of your boxers. "Fine... you'll lick my butt?"
"No! Your belly button!" she exclaims with a chuckle.
Your sibling sharply rises from the floor and moves to your stomach, before you can offer anymore alternatives. She can just lean straight forward for access, already at the perfect height. Her hands land on the tops of your thighs as her tongue extends. She dips into your bellybutton and wiggles the tip around the inside.
You count out loud for her, slowly and tauntingly, and look down at the top of your sister's head. It's so hard to not imagine her blowing you while gazing down from this angle; her thin lips bottoming out on your shaft, your cock head slipping down her throat. You place a hand on the back of her head, exploring the sudden inescapable fantasy of being your sister's first blow job.
"9... 10... 11..."
Bree pulls herself away from your grip, dramatically wiping her tongue with the back of her hand the moment she's free. Although you've never licked your own belly button (if you could reach you'd probably be too busy licking other things) you can't imagine yours as the worst belly button in the world. At the very least you did just shower so, even though you don't make it a point to soap up your belly button, it should be clean. But Bree sure seems to be handling it poorly. Really, she's exaggerating her disgust.
"That was so gross!" she whines, making all sorts of faces. "Bellybuttons are the worst!"
"No way. There are way worse things."
"Liiiike... privates?" asks Bree.
"Yeah!" you emphatically agree. "Privates would be much harder." With yours especially getting harder, and harder, and...
"Good! Then that's YOUR dare! I dare you to, um, kiss my crotch!"
The look of surprise you feel on your face is genuine. "Kiss what?" You lean back a bit, peering down Bree's swimsuit. "But... your crotch is missing."
"Well maybe you shouldn't 've cut it then!" she shoots back, her snarkiness trying to cover her embarrassment. "So that's what you get! But you're getting off lucky because belly buttons are WAY worse." She turns one knee inward bringing her thighs closer together while you stare with an incredulous expression. "But... it's not weird or anything is it? You're my brother I mean. And because you... touched it already. You are going to do it, aren't you? I guess you could forfeit." muses Bree aloud, rubbing her arm.
"Yeah, I'll do it. A dare is a dare, right?"
"Good!" Bree widens her stance and pushes her pelvis forward. "And you have to kiss it 11 times!" she stresses with a smarmy tone. She is truly on display now more than ever. Her cut up suit exposing the most intimate parts of her body, her hands moving behind her back, she looks like she's trying to show herself off to the world.
You crouch down onto your hands and knees and shuffle up to your sister. All sorts of butterflies eat away at your insides, the compounded taboos surrounding your underage sibling almost too much to process. But your inflating cock helps to put your fears to rest, leaving only the most enticing forbidden thoughts in your mind. Head up, lips puckered, you push in and smack against your little sister's vulva. Her velvety folds depress slightly as you apply gentle pressure to her hairless sex. Bree giggles at the sensation, pulling away from you for a moment before thrusting forward again, better prepared for the next kiss. And then the next. And the one after that. But she isn't prepared for your tongue.
"Eww!" She exclaims. Yet she hardly even twitches through her protests. "I said kiss not lick!"
"It's a French kiss," you state matter-of-fact before planting another. You press your face firmly against her crotch, the very tip of your tongue pushing into her labia. You angle your chin in for another go, this time reaching further under and into her supple little slit. Your probing tongue samples the dewy moisture hidden inside your excited little sister.
"All done!" Bree announces unexpectedly and takes a step back. You weren't really counting, but you were pretty sure you weren't done yet. Though when you look up and see your sister's flush cheeks it's hardly surprising to see she's lost her nerve.
"I think you're right Bree." You stand, wiping at your mouth and imitating your sister from before. "I think I would take that over a belly button."
Bree has her hands covering her crotch now, but she still has a bit of smarminess in her voice. "Well? Aren't you going to dare me? Or are you chicken?"
An eyebrow reflexively raises at that comment. If she wants the hard stuff you can give her the hard stuff.
"Oh, is that how it is? Well since you were so quick to cover up after that dare, I think your next dare should be the opposite. I dare you to spread open your privates as much as you can..."
"Easy!" Your sister quickly spreads her legs and, in a mild squat, pulls at her lips with her fingertips. She flashes her wet pink folds for a fraction of a second then pops back up and covers herself. The entire thing lasts all of 2 seconds, after which she beams a naughty smile at you.
"You didn't let me finish." Bree's smile falls away as she tries to anticipate what you could possibly add to her dare. "...for as long as I say so."
"What! But... how long is that?"
You shrug. "I don't know yet."
Your sis stamps her foot on the carpet. "But that's not fair! I already did it!"
"You sure didn't, because I wasn't finished yet." You watch your sis squirm and pout while she processes this. "A dare is a dare sis," you encourage, and also a subtle reminder of all the dares you have done of hers without freaking out.
"Can't I just dare you again?" she whines, trying to beg her way out.
"Nope. Not until you take your dare."
Bree thinks for a moment, clearly weighing her options. "Well... what's the forfeit?"
That throws you off a little. You weren't expecting her to take a forfeit, not that you had one in mind either. But as soon as she asks for one you try to deliver. Something that isn't too hard, but that should bully her into taking the dare.
"Oh, uh... the forfeit is that... I get to touch you anywhere I want whenever I want for the rest of the weekend."
Your sister scrunches up her face, somewhere between confusion and disgust. Given the direction the dares have been going she may have expected something more immediate or severe. But as her hands shift over her crotch her expression softens. Finally she lets out a long sigh.
"Fine. I'll do your forfeit."
It seems Bree is full of surprises tonight. "Really? You sure?"
"Uh-huh. Can I dare you now?"
You're not sure how well Bree actually thought about that forfeit before agreeing to it. She's far more concerned with daring you again than the long term repercussions of her dare.
"Yeah, I suppose you can."
"Good!" Her attitude quickly returns now that her power has been returned to her. "You have to jerk your thing off for as long as I want you to! So there!"
Your head cocks to one side like a dog hearing a strange noise. "For real? You want me to jerk off?"
A high pitched "M-hm!" is accompanied by a nod. You're mostly just surprised she even knows what jerking off means. You swear you didn't learn most of that stuff before you were twelve. Then again, perhaps she doesn't know; not really. Maybe it's something she picked up at a sleepover. Bree does seem to have some interesting friends given the dare she did of theirs at school the past two days.
You hesitate for a moment, scolding yourself for what you're about to do, then pull down on the front of your underwear and free your cock from its confines. You're already 90% of the way to full mast, missing the last 10% only due to the tight space of your boxer briefs. You watch Bree's mouth crack open seeing your freed stiff cock point up into the air, but she doesn't comment. You would think this is all driven by sheer curiosity more than lust, and yet that's a difficult concept to accept when you've literally tasted how excited she is with all this. Either way, you're about to beat your meat in front of your little sister.
