So far so good, but it gets increasingly challenging

PLOP

Pheobe lays a single hardboiled egg directly into her daughter's mouth.

"Eat my ass eggs, you filthy little tramp." She spits, in such a merciless tone that you wonder whether you all should have agreed on a safeword beforehand. Still, a safeword isn't the easiest thing to utter when your mouth is stuffed full of food that's been delivered there directly from your own mother's guts.

Both women continue to masturbate themselves as Carrie allows the egg to just sit in her mouth for a while, three-quarters inside, with the top section peeking out the top, indisputable visual evidence that she's currently got a butt-laid egg in her mouth right now. Your cock throbs and twitches with wild abandon. You've never been so excited in your life.

And then, Carrie starts to chew.

The first bite is glorious. Because her hands are busy down below, she has to do all the work to keep the egg from spilling out off her mouth without their help. This means keeping the vast majority of the egg within her lips, which means that her bite is much higher up than the halfway mark, resulting in two very uneven halves once she's finished. She then has to use her tongue to manouver the severed top section of the egg down into her mouth around the side of the rest of the egg, to avoid it falling away to the ground, which would cause her to lose the impromptu bet she just made with the woman squatting above her face. All-in-all, the result of this is that her tongue gets to explore a whole load of the surface area of the white object that just squeezed its way out of her mother's log slicer.

"What does it taste like?" You find yourself asking out loud. Of course, Carrie can't really reply properly right now with her mouth full, so all you get back is a somewhat whiny moan, and it's difficult to tell if she's groaning in self-pity or mewling with deep sexual arousal. Perhaps it's both.

Slowly but surely, Carrie is able to take more and more bites, and soon enough the egg has broken down enough for her to chew mostly normally, albeit still hard work because of how full her mouth is when the substance of an entire egg is in there at the same time.

"Do it. Swallow that disgusting shit!" Phoebe croons. Of course, you all know that it's not really shit, but the fact that it's come out the same hole does mean that her words help contibrute to the overall sense of filth and outrage.

Carrie emits another moan and then starts to do as she's told. Little by little, you can hear her sending bits of egg down the hatch. You can't help but grab hold of your dick and start to give it small tugs as you watch your beloved girlfriend swallow her first anal egg. Sparks of pleasure shoot through your body. Fuck, it feels so good. It feels like more than just your brain and your cock are aroused. Your whole body is hot, tense, and eager for this scene to continue to unfold.

Now that Carrie's mouth is mostly empty, the final gulps are less challenging. Soon enough, the insane task is over - she's consumed the entire egg. It's done. She's officially an ass eater, in every sense of the word.

"That was-" Carrie begins to speak.

"Shut up. Toilet's don't speak. They just swallow what they're given." Phoebe snaps back, interrupting her daughter. Before she's even finished her sentence, there's another white globe emerging from her backdoor, stretching her open once again.

PLOP

Carrie is once again gagged by her mother's rectal delivery. Unable to finish her sentence, there's nothing for her to do but recommence the arduous job of breaking down the anal payload with her teeth.

"And make this one faster. I can already feel another one on the way!" Phoebe's tone of voice is very sexual now. Is she nearing orgasm?

Carrie squeals with indignation but gets to work, chomping and tongue-shovelling as fast as she can manage whilst also ensuring that none of the delectible morsel escapes her oral clutches. Soon she's rapidly mashing the egg in to smaller and smaller pieces, and beginning to send small bits down to her stomach. But this time, she's only half-finished swallowing when the next one appears.

Phoebe wails with pleasure and attacks her clit with wild abandon as the third egg plops loose of her hole. You're pretty sure she's about to reach her peak!

"Yes, yes, yes! Swallow it all, you filthy slut! Each egg has been deeper inside my disgusting hole than the last! Each one will be filthier, stronger tasting, more unacceptably unhygenic than the one before it! Egg number three has been all the way up inside me, then all the way back down! There's no escaping that fact! It's rubbed up and down the inner lining of my passage, soaking up my filthy fucking fluids. Nobody in their right minds would want to sniff it, never mind taste it! To chew and swallow such a thing, would be... would be...!"

Pheobe emits an animalistic growl as she cums. For a moment her legs buckle a little, and her oversized ass plonks down onto Carrie's face properly, engulfing her. As Phoebe's hips buck up and down, probably mostly out of her control, Carrie's face essentially gets repeatedly sat on. Carrie is groaning loudly, but you can only hear it half the time. Each time her mothers giant glutes go downwards, her air and vocals are completely cut off.

When Phoebe manages to regain her control and posture, albeit now panting twice as heavily, you see that there were another couple of unintended side effects of all that motion and commotion. Firstly, Phoebe has essentially just used her asshole as a hammer to smush that third egg downwards, jamming it in past Carrie's jaw before she's ready for it. Secondly and even more outrageously, the upper half of Carrie's face is now drenched in some very sticky, mostly clear juices. She's had to clench her eyes shut since that entire area is just coated in the stuff.

That's just too far, right? Her mouth is so crammed full of egg that she can barely move her jaw muscles, and her own mother just squirted all over her. Carrie has to call it off here, right? Tap her mother on the thigh and then roll away, and spit out all the horrid stuff in her mouth. That's the only option left...
