Hot Summer Job/Stay silent, let Kylie speak
"...what?" says Kylie again, as equally unprepared for this as you.
"You know what!"
"What?! No I don't!" she fires back defiantly.
Carrie gives a sidelong look to you. "You had both better stop using that as an answer!"
"What!?!" Kylie repeats in frustration. Her expression instantly changes. "I mean... I'm sorry, okay?"
"Don't. That's enough. Don't say another word. I don't want to hear it. Since neither of you know how to speak anymore, you two are going to show me what you were doing."
"Show you?" you ask, a bit dumbfounded.
"Mooom!" Kylie whines. "That's not fair! I didn't do anything! Plus, hellooo?" She sways to and fro to bring attention to her body. "I'm totally naked right now!"
"Oh, so you weren't naked at Riley's house?"
"I... no!" Her argument isn't particularly convincing. Kylie looks around the room, avoiding the two pairs of eyes fixated on her and seemingly searching for an escape hatch to freedom. Her hands shift to better cover herself, her embarrassment rising.
"Jesus Kylie. How long were you even over there? An hour? Two? Did you even get your shoes off before you started flirting and flashing? And with your sister around? With his sister around!"
It's so hard to keep your grin down. Carrie knows so much and yet so little. You don't want to know how she'd react if she knew both Bree and Rissa just watched you fuck Kylie to a screaming orgasm. Carrie turns away from you both and shakes her head. Crossing her arms, she leans up against the closest wall.
"Well? I'm waiting," she declares. Neither of you move. But even with Carol's fury permeating the air you can't stop yourself from getting hard seeing this sumptuous little teen of hers squirm bare ass naked a few feet away from you. "You better start working it missy or I'll march your tight little ass through the neighbourhood and back to that sleepover dressed just as you are!"
"What?! You can't do that!"
"The hell I can't! Keep complaining and you'll lose your phone for a week too!"
That really gets Kylie's attention. It only takes a moment's thought before she obediently moves toward you. She throws her arms up behind your neck and, when you don't react, drags you down to meet her in a reserved but far from chaste kiss. You hold the kiss for a few seconds, your hands autonomously finding Kylie's bare hips, before Kylie breaks away, dropping from her tiptoes to her heels. She peers over at her mother warily.
"Alright. So that was it?"
Kylie runs a hand through her hair shifting her weight from foot to foot. "Yeah," she nods with a shrug.
"Sweetie? You're a shit liar." Carol sighs and turns to you. "Riley? Can you at least start being honest?"
You hesitate for a long while. How much of the truth can you get away with telling? Then again, it seems like Carrie wants to see the truth, like this is as much a show as a punishment. Might as well give her what she wants.
Holding your breath, you reach down in front of Kylie and matter-of-factly wiggle a finger up into her twat. She yelps in shock, quick to rise to her tiptoes again, but doesn't actually stop you. She grabs hold of your arms for stability and squeezes hard. The girl looks to her mom for help and then shamefully looks away.
"That's more like it. The truth, I mean," adds Carrie. "So I suppose you were completely innocent in this, right sweetie?"
Kylie is staring at an empty spot on the floor between you and Carrie. She clearly does not want to admit to anything. Maybe she has an "innocent little girl" persona that she uses to hide her sexual side. Or maybe she really is more innocent than she seems and talking about this is downright mortifying. In any case, you flutter your finger inside her to see if you can wake up the unresponsive teen. She squirms from the sudden stimulation then swallows the lump in her throat before shaking her head.
"Of course you weren't. Go on then. We can do this all night if we have to."
Carrie adjusts her shorts then plays with her hair while looking on with anticipation. Kylie slowly reaches out and pulls down on your shorts, just a few inches. She then teases a gap into the waistband of your barely visible underwear and carefully tucks her hand inside. Her fingers slip over then under your stiffened cock so softly you'd think she was afraid of hurting you. She's hesitant to grab hold, doing her own version of 'hover hands' here in front of her mom. She's probably hoping that Carrie won't know the difference with your clothes in the way.
"Mhmm," sighs Carrie. She runs a hand up the front of her tank top and then across to grip her shoulder in a half-hug. "Horny sex-starved teenagers. I can't say I'm surprised. What was next? Did you suck on her nipples Riley?" Carrie is wiggling her body up against the wall. You simply raise an eyebrow and shake your head. "Really? I would've," she mutters. "Well then what else did you do? Besides touch each other awkwardly..."
