Day 3 - A costly mistake

It's sometime in the wee morning hours when you stir and wake up with a tired, exhausted body. Upon parting your eyes, you see yourself still having one leg high up on the headrest of the couch, while the other foot was planted on the ground. There was nothing to preserve your modesty, with your legs so widely spread apart, your thoroughly fucked pussy had been on full display the entire time. Good thing nobody besides your dad had gotten to enjoy the view...

To confirm that it hadn't been just a bad dream, you tentatively reach your hand down to slip the tip of your finger into your aching womanhood - and you gasp in discomfort... as you wriggle your digit perhaps an inch inwards, you can feel the tampon from yesterday, still securely blocking your 'love canal' and keeping all the cum trapped inside... crap! Your dad firmly believed you were on the pill and wanted to do you a favor, but instead of just sparing you a trip to the bathroom, he did one of the worst possible things...

Ring, ring...

The phone draws your attention with its persistent noise, the main reason for why you woke up in the first place... Ring, ring...

Since your father was still asleep by your side, you quickly reach for the phone and grab it from the nearby table before he wakes too.

"Hello?" You hope it's not her again...

"Why yes, hello! Did you miss my voice? My oh my, you had some fun days! Congratulations are in order I believe!" The excited woman you dreaded to hear again was giggling into your ear. The fact that she congratulated you however was a positive surprise, did you pass the test?

"So you are saying that I didn't get pregnant after all? The cum didn't get the job done?"

"Oh yes it absolutely did. In fact you've got triplets growing inside your belly now, a rare feat for most girls and certainly a reason to celebrate!"

"Fuck! No! Stop this! Isn't there anything you can do for me?" Your heart beats faster than you want to admit. Never in your life would you have imagined that a single mistake could change everything for you! Being a girl was awful! It was way too much responsibility! It's ju-

"Naturally there's one more thing I can do for you! I noticed your sexual partner of choice and the, let's say... lack of compatibility you two shared. I can only imagine it to be rather troublesome when your lover can barely even fit inside you!" Suddenly, you feel something in your loins shifting... moving... loosening up!? While the rest of your body remained perfectly young, perky and cute, your vagina was getting slightly more... mature?! Your labia became less taut, and you could literally feel your insides getting less tight.

"W-what are you doing??!"

"I did you a favor! Your old man needed you to have a pussy that he can plow without fear of breaking it. So I went with the easy solution, I transferred your teenage bits to your mother who can actually appreciate them - and gave you hers in exchange. The ripe genitals of a middle-aged woman after years and years of daily sex. I can't imagine a better way to make sure there's no more compatibility issues! Now, since you will be stuck as a pregnant woman, I don't want you to get completely abandoned by those you care about." You could hear her fidgeting around with something, but from what you could tell, nothing else was changing...

"Done!" she chirped, but still, nothing changed visually... unless...

"From now on, in the eyes of everyone you know, you currently are and have always been - the trophy wife of your father! Gwen will see you as her mom, and your dad will be happy to have you as his darling wife! Such a young one, even! Jackpot for him I'd imagine! Don't worry about your mother, I just gave her a new life with a wealthy husband! Now ain't that a happy ending for everyone, eh, eh?"

"N-no way! I was fine with some kind of fuck-buddy situation with him, but there's no way I want to be married to my own father! What kind of sick perso-"

"Honey what's wrong?" You hear your father's tired voice, while he's reaching around you with a strong arm to pull you close, the phone dropping out of your hand.

"N-no hold on, I was talking to s-" Before you can continue, he already begins having his way with you. With the kind of casualness that can only come from years of marriage, he guided you onto your back, slid a hand down to your crotch and easily retrieved the tampon from your cum-filled cunt. The pungent scent of stale sperm wafts up from your crotch, but he immediately climbed on top of you and smoothly guided his morning rod into your pussy. There was no pain or discomfort when he entered you, it simply fit. Which was no surprise... your new vagina was shaped and molded into the perfect fit for your father's cock over the course of at least twenty years of marriage - even older than you were! You had the temptation to complain or ask him to stop... but what would be the point of that now? He lazily fucked your snatch for a good long while, and when he was close to cumming, he showed how much of a gentleman he could be by pulling out and spurting his cum across your crotch and belly.

While you reluctantly appreciate the view, you catch the familiar sight of your dad's cockhead. Big and bloated, just like it had been yesterday when it got to enter your vag from behind. Bareback and unprotected. It only needed that single chance on the couch, getting nice and deep into you, and permanently ruining your life by spitting its seed straight into your fertile flesh. And now because of your mistake, it will have a lifetime of access to your new pussy...

Smart girls get birth control. Dumb girls get morning sickness...

A silver lining appears as you hear Gwen walking down the stairs behind you, but you turn your head around only to see her completely naked with an erect appendage still attached to her crotch - one she no longer seems concerned about?! "Hey dad." She simply giggled at the sight in front of her while she was approaching the living room.
It really doesn't look like she remembers anything about the transformation, or that she used to be a normal girl! Still, perhaps she came to help you out regardless! She comes to a stop in front of the couch while stroking her girl-cock to full size with her eyes fixated on your freshly impregnated cunt. "Looks like you're done with mom. I call dibs on sloppy seconds!"

Fuck.
