Incest Seduction/Take a breath and try to better explain yourself
"But I don't...!" You nearly keep yelling but manage to hold back at the last moment to stop from spitting a tirade of justifications. Instead you take a deep breath, steady yourself, and try to take things down a notch before you give mom a good enough reason to ground you. "I know. I lost my bet with Zack. That happened. I'll take my punishment for that, whatever. It's fine. I just don't want to lose our bet too."
"And I told her already that's her problem," your brother irritatingly adds for mom. "I don't care what weird shit she's got going on with you."
Mom's nose wrinkles as she glances at her son. "You shared our bet with your brother, did you?"
"Well, yeah. I had to. Or else... y'know..." It's very unclear what anyone is supposed to know about that. But mom's been trying to pass off her bet as your new lifestyle choice all morning which at the very least reveals her own perverted interest behind everything that's been going on around you today. You exposed that. She's not impressed.
"Mhmm." You're now under mom's careful inspection. And it doesn't take long for her to spot something out of place. She grabs your right wrist, pulls your arm straight, then turns your palm up for the room to see the shimmery goopy splatter contained within. "And what's this?"
"N-nothing."
"Sure looks like something. Like something of your brother's perhaps? Was he also in a sharing mood?"
All eyes turn to Zack. You can see the color drain from his face.
"Okay, but that... that wasn't my fault. She... things got weird, alright." Zack wisely chooses to shut up after that.
She turns back to you. "Yeah, it is a little 'weird' to give your brother a blowjob."
"It wasn't a blowjob!" you emphatically counter. "It was... just an accident."
"That's no accident!" your dad fires back.
Mom sighs and nods. "I know. It has been a weird morning, hasn't it?" You nod in return. She then pauses, examining your handful of cum. "You really do want to win, don't you?"
You scoff, reflexively. Then you correct yourself. "Er, yes. I-I'm still naked and everything. And... this just..." You hold out your other hand, an admission seeking mercy. "I dunno..."
"Does that mean you wanted to ask us something?" prods mom. She obviously knows. She was probably ignoring you on purpose before. She must love the idea of you grovelling or something.
"Yeah, um... I need someone to... get me off."
"Off of drugs?" prods mom. "C'mon. You have to be specific, sweetie."
You can only bring yourself to mumble the words. "I need... an orgasm."
"Louder."
"I need you to give me an orgasm," you promptly repeat, getting it out as quickly as you can. Wanting to absolve yourself as much as possible, you then add, "Only 'cuz I lost a bet with Zack."
"...no."
"No...?" Wait, what? You didn't even realize what she said at first. Why would she say no? Didn't she offer? She said you could ask, you're sure of that. Was she never going to agree if you did? Mom lets you stir for a moment before explaining.
"Kimberley, it really feels like you're trying to offload your own consequences and responsibilities here. Did you not agree to finger yourself?"
"Well, yeah. Er, no, not exactly. Zack just said I needed to take care of my... feelings." You're still trying to be tactful, to be a good girl, as best you can be.
"And if I do that for you, do you think you'll have taken care of anything here? Besides your brother that is..." she adds with a glance.
"But I just don't want to lose th-"
Mom interrupts you before you can slip into your angry whiney voice again. "It's not that I don't want to help you sweetie, but you just aren't going to learn anything if we bail you out of your mistakes." She pointedly pulls on your wrist again. "Don't you agree?"
You glance down sheepishly at the floor. It was hard enough to ask at all. Now you're getting a lecture about it. "I dunno... I guess..."
What happens next is totally unexpected. Mom rotates your hand and drops her mouth over your thumb. She takes the entire digit in, her tongue slipping out past her lower lip to lap at the heel of your palm. She bobs up and down your digit twice then she sucks, hard, pulling back sensually. In one fell swoop your mom hoovers a sizeable portion of your brother's thinned cum from one of your hands. She sucks all the way back to the tip of your thumb then slides off with a smack of her lips and a saucy grin.
"Prove to me that you're taking this seriously. Clean up this mess of yours like a good girl and I'll make sure to take extra good care of you. My messy little girl." Mom reaches out and caresses the side of your face before dragging her fingers across your lips, all the while seductively nipping at the tip of your thumb. Dad looks nervous. Your brother can't pick his jaw up from the floor. But your momentary glance at them is all you can muster as you're finding it hard to break mom's intense gaze.
The desire you see in her is infectious. Just the look in her eye is making you wet. It should matter a lot that this raw lust is coming from your mother, but her focusing it all on you while her literal life partner, your father, watches from the sidelines is weirdly hot. It's the weirdest mix of the few taboos you even know about; incest, exhibitionism, lesbianism, cuckold, all being encouraged by your own mother. She is urging you, wanting you, daring you. Seeing that raw heat in her, a sparkle in her eye, with butterflies in your stomach, you are hardly able to think. Driven by pure compulsion, and unravelling under such an intense gaze, you lift your free hand up to your mouth. Without breaking eye contact you place a long lick up the center of your palm and all the way along your middle finger, collecting a thick ropey dollop of cum on the tip of your tongue.
Mom glides her tongue around her saucy grin as you place lick after hungry lick over your hand, snacking on your older sibling's semen. Once you finish and move to the other hand she inches closer to you. Grabbing your hips, she smoothly works her hands around to your bum before eagerly spreading both of your cheeks, greedily gripping your ass. The very next moment she's pushing you up against the cabinetry. Mom lifts one of her knees, her leg appearing from under her robe and forcing its way between your thighs. She presses her own thigh up against your underside and plants her knee against a drawer behind you for support. Pulling on your ass she gently rocks you against her leg, encouraging you to grind your young teenage sex against your own mother.
"Ahem," your father chokes out, the first thing anyone has said in the last minute. "We should... give them a moment, son."
"Your daughter wanted an audience, James," your mom confidently replies, watching you clean your last finger. She then glances at her son and adds, "That's the least you can give her."
As soon as you pull your finger from your mouth mom shoots forward to lock lips with you. She's gentle but firm, encouraging and rapacious at the same time. Her sincere affection while forcing you to grind against her leg is both confusing and enrapturing. It's almost enough to make you forget you're standing completely naked in your kitchen making out with your own mother in front of your family. Almost. It's just a little too jarring to push all that to the back of your mind. But whose fault is that? You did literally ask for this.
Daddy tries to make small talk with your brother as mommy ravishes you. Something about how he's never understood women, that you've been so hard to deal with lately. Part of you wishes the boys would go away. You're on pins and needles here with a flurry of taboos already making you antsy and uncertain. And yet knowing you're being watched doing this, aside from all the embarrassment, somehow makes you just a bit wetter. Weirder still, you've had fun with both of those cocks so far this morning. If anything this show you're putting on is meant to tease and taunt them, maybe emasculate them, that only your mommy knows what you need. Except your mom is way past teasing.
Letting go of your ass, mom quickly glides her hands up your body. Rubbing your torso from your hips to your neck she lingers on your chest for some time, tweaking your nipples and squeezing your tits for you and providing some mix of relief and pleasure. You've had to keep reminding yourself not to grab your boobs all morning which has been so hard while being this horny. Mom then unexpectedly breaks your kiss and drops to a crouch in front of you. Your pelvis was still rolling as she took her leg away from you and you instantly look down with disappointment. But then she forces one of your knees to the side, pinning it against the drawers, and sends a tingly bolt of lightning up your spine when she starts tonguing your clit.
"AHHhmmm-mommy!"
Following your elated gasp you plant your hands onto your mother's head, partly to stabilize yourself and partly to hold her firmly in place. You had no idea your mother's tongue would feel utterly magical flitting up against the tiny nub between your lips. You sink your fingers into her hair with a blissful shudder, no doubt rubbing the lingering scent of her son's cum into her scalp.
Mom's tongue is ravenous. She dips between your folds and flicks your clit as if she owns your pussy and always has. The confidence and enthusiasm your mother has in eating you out makes you dizzy with lust. And that's before she inserts her fingers.
"Nggh!" you shout with a start. "Mmmommmy..."
Two digits penetrate deep inside you. They are quick to curl and stroke what you can only assume is your g-spot. You'd heard that was a thing but you have sure never found it. You would have remembered. Her fingers are making your clit throb.
"Awhh gawd... sh-shit."
"Enough of that sweetie." Your dad is always quick to remind you about your cursing.
"B-but... I... oh fuck!" Mom is suddenly doing double time on your clit, her tongue bouncing over your tiny button.
"Sweetie, language," he warns again.
"Da-daddy... this... Ffffff-uck me... Oh my gawd!"
Somehow mom's lips slip around your clit to draw it into her mouth, sucking hard on your sensitive nub while rubbing your insides. You're so close now.
"Oooh daddy! Daddy! Fuck me! Yes! Yes! Fuck me!"
Daddy takes a step forward. "I should, just to teach you a lesson."
Mom breaks the seal on your clit then turns to her husband. "I'm doing all the work here and she can't stop calling for you. Frankly, I think you should. Give her what she wants."
You're panting and groaning with frustration now. Why did mommy have to stop? Her fingers are fluttering but you want her on your clit. You try to turn her head back towards you but she responds with a few mini thrusts into your pussy, an order telling you to behave as much as anything.
Daddy sure is taking a long look at you. He looks like he wants to say so much but he's dead silent. In fact all the chatter has stopped. It was already tense in here but now it's downright scary, everyone staring while mom's fingers are still inside you. It was easy enough to ignore the tension while wrapped up in your arousal but now it's like they're waiting for you. You suppose you need to say something.
