The car ride continues in relative silence after that, with your mothers paying attention to their own things, and the girls on either side of you falling quiet. But Summer is a person who grows easily bored, and who from boredom grows quickly mischievous. It isn't too long after that when you feel her fingertips playing up the side of your thigh.
A jolt of raw panic rips through you. "Stop," you whisper out of the side of your mouth.
"Make me~" Summer whispers back.
You glance desperately up front. Your mothers are both distracted -- for the time being. N-Mom has her eyes planted on the road as computationally instructed, and K-Mom is fiddling with the online portal of the same old Thai place she always orders from (despite claiming every time is the last time she'll ever eat from there).
"Just a little fun," Summer whispers hot in your ear, and nips your earlobe for effect. "It's fine."
"Summer..." you whine.
Your mommies don't notice, but your sister sure as shit does. Playing at innocent and unaware, she stares out the window, while meanwhile her fingers snake up the side of your other thigh.
Summer pauses. She knew already that you and Amber did sexual things together... and she probably had to figure that Amber might even notice her getting handsy. But it still surprises her, if briefly, to see Amber joining in. But Summer's surprise morphs into a dopey grin. And so she starts giving you something better than teasing, tickling fingertips on your thighs. Her tickling turns to heavy petting. Summer strokes your leg with the meaty part of her palm, gripping you not a little roughly, as she rubs and massages you. Amber mimics her.
"Please..." you whisper, to Summer and Amber both.
"Shhhh," Summer coos.
In silence, Summer and Amber work in slow circles around your legs, each finally finding their way to your inner thighs. You're helpless. The last thing you want is to make a fuss fighting back against these two and have your mothers catch you. So you just sit there and hope it will all be over soon. In your heart, you know this ends in only one way. It ends with you cumming, and not a second sooner.
The two pull out their phones, and make no secret of texting each other. They, probably purposely, allow you to see their screens.
>Wes's moms are super cute
>Right? First good opinion you've ever had. Yeah. They're hot.
>Think they would be down to hook up with me?
>ofc. those broads are gayer than the 1890s.
Summer stops rubbing your leg, and gives Amber a confused look. Amber glances back and mouths something that looks like -- "it's a reference." That satisfies Summer well enough, who shrugs and goes back to texting:
>Have you been fucking Wes for awhile?
>Oh years. Does she eat pussy good?
>Fuck yea.
>You're welcome :)
> ❤️
You can't help how wet you're getting from being toyed with like this. You hate yourself for it, but there it is. Your pussy is getting all puffy and throbby and wet inside your panties.
Summer is the first one to take the bold next step in this act of molestation. She unbuttons the brass clasp of your jeans and unzips your zipper. You feel as exposed by this as if you were stark naked, and the sound of the zipper coming undone, even as slowly as Summer tugs it down, sounds to you like an atom bomb. You bite your lower lip and just wait for either of your mothers, or both, to wheel on you. You shiver like you've been dunked in ice water.
Summer reaches down your front. Amber reaches down your back. They have you trapped, and they don't waste any extra time going in for foreplay. This is a quickie. They want you to get off hard and fast. Summer's fingers wiggle past the crotch of your panties to prod and probe your juicy cunt. Amber's hand slips past the elastic waistband to spread your ass cheeks and play with your tender rear hole. Somewhere between those orifices, their fingertips meet and interlace. You gaze down your front, half disbelieving, as right here in broad daylight and not two feet from your parents, your fuck-friend and your older sister finger you in tandem. Your pants bulge from Summer's knuckles.
They grow bolder still. Grinning at one another like the evil bullies they are, they get their hands under your sweater as well. This is too much. They're openly groping you all over, like they're just begging to get caught. They paw at your tiny tits, mauling them and pressing down on them. It hurts. It *really* hurts -- their cruel hands are after their own sick pleasure, nothing more. Your breath hitches. You stifle a moan just before it escapes you lips. To wordlessly shush you, Summer presses a finger to your lips -- then presses it further, beyond your lips, and into your mouth. But she couldn't have forced it in, past your teeth, if you didn't secretly want it there.
Amber follows suit. They go from groping your tits to running their fingers around in your mouth. Over your tongue, across your molars, against your palate -- down, into your esophagus, testing how well you've got your gag reflex under control. They use their fingers to explore every nook and cranny while your jaw hangs stupidly open and drool runs down your chin. They fishhook you together. They pinch your tongue between thumb and forefinger together. And all the while, their other hands stay busy inside your lower holes. These fucking bitches are abusing all three of your holes like you're just a cheap whore they bought for the night... so why does it make you so excited that you almost feel nauseous from the thrill of it?
These two girls, usually so combative, are totally synchronized in mistreating you. Amber spreads the two fingers she has up your asshole as wide as she can, forcing it to gape open. At the same moment, Summer starts to rub her thumb in quick little circles around your engorged clit. They saw their fingers in and out of you like they're trying to dick you down. You wrench your eyes tightly close, and swoon, but they keep you held steady between them.
You can't hold out. You cum from getting molested. As always, you take a sharp breath and pinch your knees together. This sudden noise perks N-Mom's ears and the movement flags her peripheral vision. Her eyes shoot up and meet with yours in the mirror. Your face trembles and twitches. Your drooling mouth goes droopy. Amber and Summer, totally uncaring about being caught, pry your legs apart -- to show you off like you're a toy -- to show your own biological mother how they're fingering you to orgasm, and how the wet spot from your cum seeps across the crotch of your jeans. N-Mom doesn't say a word. She just watches on, and her expression is inscrutable. Beside her, your other mom is oblivious. For now, this nasty secret is between you and N-Mom, and it seems like she's going to be willing to keep it. For now.
The wet spot grows at that last thought. At "for now." What will she do next? You close your eyes, too humiliated to look at her, and let yourself finish cumming. Your brain melts as you feel your underwear growing sloppy, as you feel the backs of your thighs begin to drip. Amber snickers. Summer nibbles your ear. And although you can't see her anymore, you know your mom is watching everything, everything.
