Neither! You didn't agree to any of this!

"You want me to decide who gets to knock me up, and you make me choose between my own brother, or my jerk-bag father? How about neither? It was stupid of Jimmy to spill the beans in the first place, even more silly that I thought I could stay here for a while. I'll just head out for a couple days until that oh-so-blessed twat between my legs is gone and I can lead a normal life again."

"Oh no you won't," your mother responds as she grabs you by the ear, pinching down hard as she gets up and begins leading you out of the room and upstairs. The whole time you whine and cry, "Eeep, stooop, ahnn, nuh-uh!" The two of you soon end up in your parents' bedroom, and your mom pushed you right in before finally letting go of your ear! Eww, you immediately notice the faint scent of sex around you. Dad must've taken your mother for a round earlier today... you turn towards the bed and see him there, sleeping peacefully, naked and fully exposed. His flaccid dick was coated with remnants of pussy juices, no doubt your mom's... jesus...

'Click', you turn around and see that your mother had left the room and locked the door!

At the same time, you hear movement behind you and turn back around, only to see your dad already sitting upright while stroking his still soft appendage, using the remains of your mom's juices as makeshift lube. "Mmh. Now that's a pleasant surprise to wake up to. Hey, who would've thought that my own son would turn into a pretty young girl some day? Looks like you want me to be the baby daddy then? How about you lose the bathrobe?"

Sheesh, creepy. "No! I told mom that I don't want anything to do with this. I want to change back to my former self!"

"But that wasn't one of the options she gave you, now was it? Come on now, you're a little too old to play the 'hard to get' game. Strip naked and spread 'em, we can't waste time just because you want some courtship... clock is ticking and we need to get a baby in there," he says while pointing at your flat belly.

"What!? No! That's not why I'm doing this! I seriously don't want anything to do with this," you point out as you turn towards the exit, grab the door's handle and begin tugging and pulling on it to try and **** the door open but without success. Out of nowhere you suddenly feel strong hands on your shoulders which grab your bathrobe and suddenly shove it downwards and off your body, revealing your naked beauty. Your father pushes himself against you, sandwiching you tightly between the door and himself. "G-get off me!"

"Not gonna happen, son. First we gotta make sure that you get to keep your new genitals." Just like that, he suddenly kicks your legs apart and you can feel him guiding something smooth between your labia. With a quick push, that something is being shoved right into your womanhood, stretching your cunt wide open to accommodate your father's erection. "F-fuck!" you groan out loudly as the massive thing splits you wide open, but it only earns you a slap across the cheek before your dad continues trying to push deeper in. "Shush, son. An obedient girl doesn't speak during sex. Your only purpose is to make men feel good, and to take care of the clean-up afterwards by keeping the cum inside you instead of getting the bed dirty." He chuckles as you involuntarily squeeze down on his dick.

He begins rotating his hips a little, thoroughly stretching your lady bits apart and renewing the damage he had done yesterday. A few more times like this, and you will permanently lose your pubescent tightness just to be able to take in an adult sized cock. "Speaking of that, you're also not allowed to use any birth control unless you've got explicit permission from me. You're still young and flexible, we can get a couple babies out of you before you should even consider using protection. If that makes you uncomfortable, just remember it's the natural way to do things. Couple hundred years ago, sex was always bareback. It's a timeless classic," he explains as he begins pushing in so deep that you could feel his heavy testicles nudging against the lips of your pussy. Fuck! It feels like he was shoving an entire fist into your crotch. Gritting your teeth, you try to endure it.

Back and forth he goes, carelessly enjoying the snug grip your cunt provided and claiming you as if you were little more than an object. "S-stop it!" you hiss aggressively, and he once more slaps you across the cheek before pushing even harder into your twat, making you cry out as soon as the bulbous tip of his organ rubs up against your delicate cervix. "Shush. Don't make me repeat myself, girls aren't allowed to talk during sex." In the meantime, he keeps sawing in and out of you, a process that was soon joined by a slippery noise each time he pushed in now that your pussy reacted instinctively and began getting wet on its own.

Too little, too late, as he suddenly throws himself against you and keeps you tightly compressed against the door, right when you feel his dick twitching and pulsing against the comforts of your little vag. Rather than objecting again, you reluctantly remain silent and try to ignore the excited throbbing of his appendage. Even his dick seems to know that you're completely unprotected. A steady stream of lukewarm semen gets injected into your most intimate parts, and your vag is mindlessly swallowing every last drop of it.

Once he was spent, he slung his arms around you and picked you right up to carry you over to the bed, and he carefully placed you on it without slipping out of your fleshy sheathe until you could feel his heavy weight on your back. Then, he reached for a pillow and stuck it underneath your crotch before settling himself fully on top of you, while your face was pressed against the dull mattress. "There's that my son," he announced with a weary but satisfied tone. "Now we just need to let all that goo leak all the way in, and it's done. I may have failed raising your sister correctly, but that's not gonna repeat. This is definitely more fun than all the times I took you camping and fishing. Just your daddy and the embrace of your naked cunt."

You could feel it getting warmer inside your belly, as your father's seed began to ooze and dribble into every corner of your womanhood. Shit.

Much like your dad however, you're a sweaty exhausted mess after that drilling... with both of you panting and sighing, you don't even notice yourself gradually relaxing until you're deeply asleep...

...

... ...

You're waking up to the sensation of something stretching you open, and even in your groggy state you realize it's your father's appendage... again. As you open your eyes, you find yourself still in the same position as before, flat on your belly while your dad was heavy on top of you. Except this time, he was lazily sliding in and out of your womanhood, spilling your own wetness to make room for more of his seed. Worse yet, you could clearly tell that your body was responding to the treatment. The thick smell of your wanton pussy was heavy in the air. It was creepy how excited and eager your cunt was at the thought of fulfilling its biological purpose.

There was little doubt remaining that your father was fully awake and aware of what he was doing when he began speeding up, a persistent squelching being coaxed out of your genitals with every other push forward. "Ahnn.... nhhh..." you can't help but to groan in protest each time he shoved himself into your far too small vag. Your crotch was even more sore than the day before, and you were particularly aware of how deep your dad's erection was reaching into you because of that. Crap, you also remember that he had come inside of you once already! Maybe that's why your pussy was so wet and happy. Instead of finding a chance to get away however, you feel the pounding you're receiving become even more primal and harsh, every push forcing you tightly against the mattress while your dad was mechanically mating you without a word.

It only came to a stop another minute later, when he moaned in satisfaction while shoving his crotch snugly against your bum cheeks to bury every inch of his manhood inside your twat. The familiar pulsing follows right after, and you can imagine the millions of additional troopers he's depositing in your twitching cunt. It was literally pouring into you, like he was hosing down your insides with his sperm. So gross!

SLAP, His hand smacks across your buttocks while he gets up, satisfied with the deed once he had drained every drop of seed into your crotch. If even he was confident that you're well on your way towards a teen pregnancy, then you've got plenty of reason to worry. Before you had a chance to slip away, the bedroom door creaks and opens and you spot your mother stepping inside - and getting an eyeful of the lewd connection you shared with your own father, his veiny appendage partially buried inside your womanhood while strings of white goo were connecting your crotch to his. Couldn't get more humiliating than that...

"Dinner's ready," she chirps happily while approaching, as your dad pulled his bloated organ out of you until it slipped out of your abused slit with an embarrassing queef. "You two make a cute couple! Still, it's time to eat." She's quickly making her way over to the nightstand by your side, opens a drawer and retrieves something... a tampon? You couldn't even question her before she already moved her hand down to your entrance and shoved the object into your tender pussy. "Ou-ouch!" Almost instantly you could feel the stupid thing absorbing your cunt's wetness and doubling in size, thus perfectly sealing in your daddy's semen which had been deposited much deeper and closer to your cervix. "R-really?" you protest sarcastically with a pout, but she didn't care.

In the meantime, your father had gotten up to put on a shirt and some underwear. After that, he casually tossed you the bathrobe you previously wore while your mother began wriggling her finger into your lady bits, effectively pushing the tampon as deep as it would go until a majority of the sperm was neatly packed into the very back of your pussy. Done with that, she simply pulled her finger out and wiped it clean on your bum cheeks while you glared at her.

"Join us downstairs when you're ready," she winked back at you, and just like that she left the room together with your father.

It was easy to tell that they had twenty or so years of experience with baby making. Just a couple hours passed, and you already had billions of your daddy's lil' tadpoles breaching your cervix and wagging their little tails in excitement while they were drawn to the pheromones that your eggs released. At this rate, mom will get her wish and you will become an adorable teen mother against your will...
