At the speed of sound!!!

As soon as Carrie's mother gives you the green light, you are packing your things and getting ready to zoom out the door. You are **** for this to happen before either one of them changes their mind!

"Aren't you forgetting something?" Carrie nods towards the kitchen with a big smirk on her face, arms folded as she watches you.

"Eggs!" You exclaim. Conveniently, there's a pack of 12 eggs Carrie had bought just that morning, so you stuff those in your bag and then sail out the door, hand-in-hand with the best girlfriend in the world.

As it turns out, it wouldn't matter if you had forgotten them or not.

Carrie's mother is wrapped up snugly in a mauve dressing gown when she answers the door twenty minutes later.

"Come in quickly, sweeties." She almost whispers, as if this secret late night rendezvous would looks suspicious to any nosy neighbors that happened to notice. But surely, to anyone watching, this would look rather innocent. Just a woman and her boyfriend visiting her mother.

"Before we go any further, can you please confirm to me that this is serious, and not some weird prank." Carrie's mother says firmly after she's closed the front door, repeating almost word-for-word what Carrie had asked you when you'd first suggested her mother.

"We're completely serious." Carrie replied back, in that same no-nonsense tone.

"We wouldn't ask such a crazy thing of you if we didn't really want to do it, ma'am." You say as politely and respectfully as you can. "I assure you, I'm just as nervous as you are."

"That's sweet of you to say, honey." Carrie's mother smiles and speaks warmly now. "And please, call me Phoebe."

Your girlfriend's mother Phoebe is a very similar height to her daughter, but boasts an even more impressive figure. Even through the thick purple wool of her gown you can make out her prominent bust and wide hips. From having met her before, you know that behind her she is sporting a positively dumpster-truck ass. What was already an impressive derriere in her youth has been amplified by a diet of chocolate and red wine. Sure, it means she's rather full in the middle too, but that's not a problem, and pretty standard for her age. Overall, she's exactly what Carrie would look like if she was a 48-year-old chubby thicc MILF.

"Okay... Phoebe." You say. It feels weird to call her by her first name. Somewhat disrespectful. But you're about to watch her do something very degrading in front of you, so in comparison this isn't a very big deal. "I, um, I brought some eggs." You produce the carton of eggs from your bag.

Phoebe turns red and coughs. "Um, actually, that may not be necessary." She says very shyly. "You see, after Carrie ended the call, I went and boiled some eggs myself. Thought it might save some awkward waiting time."

"Hmmmmmm." Carrie hums, looking entertained. "I wonder."

"What?" Both you and Phoebe ask, you with curiosity and Phoebe weirdly defensively.

"I think my mother is more excited about this than she's letting on." Carrie accuses playfully. "It makes sense really. If I'm a huge pervert, I probably inherited it genetically. And I never felt judged whenever you caught me experimenting in my teens. If anything, the looks you would give me were... pride."

"I don't know what you're talking about." Phoebe replies haughtily, but also playfully.

"Hmmmmmm." Carrie repeats. She slowly walks all the way around her mother, with a hand on her chin, as if she's thinking deeply.

"What are you-" Phoebe starts, but is interrupted.

"Tell me mother, where are those eggs you boiled right now?" Carrie asks innocently.

There's complete silence. Phoebe's face is quickly getting redder and redder.

"They must be in the kitchen, right? Still in the saucepan, perhaps? I'll go get them!" Carrie offers happily.

"There's no need." Phoebe says quietly.

"And why would that be?" Carrie asks just as innocently as before.

"Because... because they're already in my ass." Phoebe admits in a squeaky, ashamed voice.

"You fucking pervert, mom." Carrie announces triumphantly. "You can't wait to shit them into my mouth, can you? You're probably wet just from the thought!"

"Oh god, this is so embarrassing! Sweeties, I'm so sorry, I'm such a disgusting deviant." She's talking to both of you, but her head is lowered and her hands are covering her eyes.

You cough, trying to find the right words. "Well, um, well then, you're in good company." You offer.

"Ain't that the truth." Carrie agrees with a smirk. "Here we are, three filthy fucking perverts, about to engage in an extremely unholy act. And I'm willing to bet that all three of us are already rather turned on. I know I am."

Carrie raises her skirt and lowers her panties, removing them entirely. She holds them up to you and her mother.

"See? Look, drenched already. I would suggest you make me gag myself with them, but that would kind of prevent me from eating my mother's ass eggs, wouldn't it?"

"Oh fuck. Okay, fine, I admit it. I'm so fucking horny." Phoebe lets her dressing gown drop to the floor. Underneath she is wearing... absolutely nothing. She's just bared her entire naked body for both of you to gaze upon. It's everything you imagined and more.

Unlike Carrie's smooth and completely shaven pussy, Phoebe's has a hair unkempt bush. Still, her prominent labia are clearly visible sandwiched in between two thick thighs. Her magnificent melons dangle freely, sagging under their own weight but thanks to their stupendous size they are still throughly motorbotable. Her tummy and buttocks are covered in stretch marks and cellulite, giving her an authentic homely look, unlike those airbrushed Playboy models and the Intsagram influences with their fake filters. The thought of those massive buttcheeks being spread to engulf your dear partner's face sends blood rushing to your penis.

Carrie notices the bulge forming and eagerly moves to free the beast. "You don't mind, do you?"

You're not even sure if she's asking you or her mother but it doesn't really matter. Either way, it's not long before your own bottoms are around your ankles and your throbbing member is exposed to the air.

"I imagine you might want to touch yourself while we do this." Carrie suggests sexily, and then takes you by the hands and guides you into the living room. "Where do you want me?"

You assume that this next question was directed at you, but Phoebe answers first. Her voice is shaky but she's doing her best to act dominant. Perhaps she's leaning into some fantasies of her own. "Lie on the couch and dangle your head over the side, young Miss. Filthy stuff has come out of that gob for too long. It's time for something filthy to go in, for a change."

Carrie complies quickly and eagerly. "So you want my head all hanging off the edge of the armrest like this, so my mouth is pointing directly upwards, perfectly positioned for use as a face-toilet?" She oozes arousal as she speaks. Carrie's butt is on the sofa, and her neck is supported by the armrest, meaning that her head is still higher than the rest of her body, which will allow gravity to assist with moving anything she swallows in the right direction.

"Yes, you little toilet SLUT!" Phoebe is really getting in the mood now. You see her flick her clit a couple of times as she approaches her daughter and then turns around, that giant ass looming over Carrie, threatening to suffocate the poor small girl underneath.

"Oh god." Carrie sounds scared and aroused. "How many eggs are up there, exactly?" She asks timidly.

"Fuck around, and find out." Phoebe says as she lowers her humungous butt down, until her asshole is less than an inch from Carrie's lips, and the tip of Carrie's nose is able to feel the wet central slit of her mother's engorged pussy.

"Let's make this interesting, slut." Phoebe is getting lost in her sexual frenzy, and her voice is now positively dripping with dominant venom. "If you can't swallow everything I give you, without missing a drop, then for the next month, every single day you'll have to have one of your meals be entirely things that have been in my ass. Understand?"

Carrie gulps, but instead of refusing the ridiculous offer, she just moves one hand under her skirt and begins to masturbate. "Yes Mother."

"There's a good girl. Now... here comes the aeroplane..."

You watch as her ring, a part of her that you should never have even been allowed to see, begins to dilate, and a white dome slowly begins to emerge from inside, forcing her sphincter to open wider and wider. Phoebe shamelessly rubs at her own clit as the first hardboiled egg makes its move.

"Aaaaah~" Carrie leans into the roleplay, opening her mouth wide and making an accepting sound.

You've somehow ended up the only person in the room who's not masturbating. Which is probably just as well - your lack of hand action is probably the only thing that has avoided you orgasming before it's even properly begun.
