Caris doesn't do "lunch" in the traditional sense

“Hmm?” Your mom said, tilting her head back to watch the two of you walking in.

Caris plopped down on one of the chairs by the counter, quickly getting together a few ingredients for her own sandwich. Her big tits sat heavily on the counter while her similarly capacious dick and balls hung over the edge of her chair as she worked. You moved quickly with your sultry sway to sit beside her, all the while keeping your head down.

“So” your sister said conversationally. “How’s sex with dad been lately?”

A knife clattered, dropping from your startled fingers. Had she really just said that out loud?!

Your mom meanwhile just raised a hand as she leaned back, relaxed, waiving it in a “so-so” motion.

“I mean he’s good to me and all that but the nagging can get old, he still acts like we’re 18 sometimes by the way he’s always wanting to fuck like rabbits.” Your mother said, straight faced as if it was the most natural thing to talk about her sex life with her children.

You stared at your sister, annoyed that she was taking advantage of your mom’s lack of decorum when it came to, well… anything.

“Sorry, could you repeat that mom?” Caris asked, biting her lip as her finger quickly toggled something on the screen.

Nami rolled her eyes looking at her daughter with a “you would” stare. Still she responded, as you knew, she didn’t care if you and your twin knew these sorts of things.

“I was saying that your father hasn’t been enough lately, at most he can handle two, maybe three times a day and that’s just hardly anything for an animal like me.” she said, as she shucked her pants, diving down with one hand to start pleasuring herself.

You looked away, embarrassed to see your horny mother stroking herself like this.

She was always doing stuff like this, unabashed at others knowing she had a ridiculous libido, she often scared off less… “creative” individuals.

“Oh?” Caris asked, her expression suddenly very interested, watching your mother’s humping hips and the rhythmically moving fingers below the white panties covering her slit.

“G-yeah, gonna have, fuck, to get off several times before he mm… get’s home or else I’ll be pestering him all night.” she said between heaving breaths, her heavy tits moving with her chest.

*thunk*

Your sister cringed slightly as the counter before you shook with the collision of something. She cursed quietly, looking down at herself between her plush tits, mumbling something about “idiotic supreme power” or something.

She pushed her seat back, once more looking up at Nami’s masturbating form. Her cock stood proud as ever and pointing straight out and past her soft legs towards the counter.

Ah, so that’s what the noise was about.

“Don’t you want a helping hand with that mom? If you’re going to do it right in front of me, making me so hard then you might as well let me join in?” she asked, with a slightly pained look on her face.

Nami didn’t stop her already heated caress of her hidden quim, she tilted her head again to get a clear view of you and your twin with a look, not of shock or horror at Caris’ words. Instead she only gave a look of mild annoyance.

Sighing, her finger’s quick motions slowed enough to speak semi-coherent.

“Sorry honey, I’d be all for it, but dad would have my hide if he knew I fucked you kids.”

There was no chastisement in her words or even any sign of embarrassment. From what you could tell, that was just your mom’s honest to god's position on the matter.

You didn’t even know why your sis had asked her in the first place, while Nami had no reservations about breaking social constraints when it came to sex (she’d perved on you and your sibblings many a time before), you’re dad was a whole other matter. He knew first hand about your mom’s eagerness for getting off constantly and had been firm on the point that she was not to engage with the kids.

It didn’t stop her from fondling herself in the kitchen though.

Regardless of her unabashedness when it came to her sexuality, Nami could recognize the importance in keeping her husband’s trust, something which was a mild point of pride to you at the very least.

Caris grunted with annoyance beside you.

“What the fuck does a girl have to to do…” she mumbled, looking at your phone.

You sighed, watching the familiar sight play out before you.

Now what would she do?
