"Oh." Miri felt disappointed. Bill had all the fun that night because she'd only blown him and then they'd fallen asleep. Well, she'd make sure to wake her father up with a good ride. "Nh." She felt her pussy tighten up a little at the thought. She went to bed, again forgetting to take her nightly birth control pill.
Back in her own room, Dove lay on her bed and looked between her legs. "Oh wow..." Some of her father's semen had dried on her vaginal lips but she could see some of the white liquid peeking out from between them. Deep inside her, she knew, lots of his unseen sperm were eagerly searching for her egg. She reached down and rubbed at her prominent clitoris, taking a little of her father's escaping semen to use as lube as she jilled off. It only took a minute for her to cum again, her back and hips instinctively arching up to give her progenitor's sperm that little extra advantage once more.

In the morning, Miri found her father already awake and straddled the man, not even noticing that his cock had his and his younger daughter's cum on it before she took it back inside her own overheated pussy. She'd fallen asleep masturbating, so was horny as hell, riding the man like a ravening beast until they came together.
"Yes...fuck, yes..." she moaned as she felt her father's sperm permeate her slightly-less-than-protected depths, her body shuddering as the warm, throbbing sensation made her cum hard. Then she gave her father a less-than-daughterly kiss before getting ready for school.

Miri and Dove's father headed to the kitchen to get lunch and found Dove bent over, looking into the fridge and wearing only a bra and panties. "Uh..."
"Hi Daddy!" the pretty ash blonde greeted him, closing the fridge and turning around to give him a full frontal view of her hourglass figure.
The man was so taken aback that he didn't realize that she hadn't taken anything out of the fridge. "Uh..." He'd seen her in a one-piece bathing suit, of course, but such sexy underwear had him inadvertently bulging out his pants.
"Uh oh, looks like you need my help," the 18-year-old commented, got to her knees, and dropped his trousers. A moment later, she was gobbling up his cock.
"Oh fuck..." he moaned. His youngest was getting better at that.
She pulled off and led him by his erection to a chair. "Why don't you have a seat?" Once he did, she took his length back inside her hot mouth. When he closed his eyes in ecstasy, she quickly straddled him, pulled her panties to the side, and took his entire length within her hot, wet pussy.
"Uh, baby? Shit! But you're--- were a virgin!"
She began bouncing upon him. "I was, Daddy, but I helped you last night, not Miri." She pulled her bra up to free her C-cups with their hard, conical nipples.
"But...I came in you...you're not on the pill..."
She noticed that he wasn't trying to stop her, though...in fact, his eyes were locked on her bouncing bosom. "And I'm right in between my periods, *Daddy*. There's no point in pulling out now, as you've most likely already knocked me up. Mmm..." She leaned forward, putting her mouth right next to his ear. "Do you think I'll be cuter with a little baby bump?" She felt his cock somehow get even thicker inside her and moaned as he grabbed her hips and lifted. But instead of disentangling their bodies, he pulled her back down, causing his cock to delve as deep inside her as it could go. "Yes, Daddy..." she moaned. She could feel an orgasm rising from where the tip of his cock rubbed along her spongy cervix. "Yes..."
He pulled back and lifted one of her breasts up to his mouth to suck on one of her prominent nipples. His grip on her hips became more intense and they moved as one, increasing the speed of their coupling.
"Oh, Daddy, do you think my boobies will get bigger?"
With a growl, her father lightly bit her nipple, making her cry out. A moment later, he grunted as he spurted a fresh load of babymaking sperm deep inside his youngest daughter's fertile, unprotected insides.
"Ohhgoddd..." she moaned as she felt her own orgasm blow through her primed body. Her cervix spasmed open in time with her pleasurable release as her father released spurt after spurt of his dangerous seed upon it. When their spasms lined up, one particularly intense burst of potential life was given a clear shot straight into her baby chamber. "Guhh...Daddeeee..."

The incestuous debauchery continued for another week, though Dove had been impregnated by her own father on the very first night in his bed. As she slept after jilling off, his sperm had found her vulnerable egg and swarmed it, unconcerned about the similarity in their genes. By morning, the fertilized zygote had implanted itself in the wall of her uterus. She was unaware of this, however, and kept urging him to fill her youthful, sexy body with his baby.
Miri remained unaware of her baby sister's condition and the fit brunette continued to assist her father at night and in the morning by taking his load inside her body, intensely cumming herself. Half the time she remained in his bed because she would have just come back in the morning anyway. She still hadn't taken any of her birth control pills since her father had first cum inside her, always forgetting or becoming distracted when she started thinking about it. She seemed to be very distracted lately, and it was affecting her grades.
She also kept putting off another date with her boyfriend Bill, though she couldn't say why. The thought of the young man cumming inside her almost made her retch...that was for her Daddy! Finally, she broke up with the young man over text. *It's not you, it's me,* she informed him, and while it was a trope, it was also absolutely true.
She was riding her father particularly hard one morning. Her B-cup breasts felt a little bigger than usual, and sore, and when her father tried to suck on them she pushed him away. She was chasing an orgasm, one that was tickling her from deep inside, just beyond where the man's thick cock punched away at her lowered cervix. She saw the man in the elevator again, telling her and her sister the new way of things...she was going to cum...
"UNGH!" her father cried out as he came hard, pressure-washing her cervix with potent, incestuous sperm.
"Uh-hk!" Miri's body stiffened as that deep orgasm blossomed like a flower watered by a white rainshower. She pressed down upon the man, connecting the tip of his cock right to the entrance to her womb, allowing the next burst of his seed to saturate the depths of her uterus. "UHH!" She collapsed upon him, her body seemingly made of rubber as her father impregnated her.
A part of her mind, trapped since the day in the elevator, knew what was happening. Then she realized that when she gave birth to her father's baby, there would be a new family member and the rules of the house that were implanted in her mind would remain in effect. Not able to think about that horror for more than a moment, she instead wondered about the elevator man's compelling suggestion that it was the duty of the women of the family to help with the men's sexual tension. The wording was precise, as if he'd honed it over years. She wondered how many others he'd refined it on.

In a nearby town, a thin, 21-year-old redheaded woman let her overweight, dark-haired, 18-year-old stepbrother rub one out along her panty-clad pudendum. She didn't like giving head and he said her hands were too rough, so this seemed to be the best way of just getting it over with. Despite her disgust at her younger stepsibling's lechery, the taboo feeling of his hard member rubbing along her pussy lips through her underwear was strangely thrilling.
One state over, a voluptuous mother used her mouth to help her 20-year-old son with his morning wood. The 43-year-old woman had rebuffed her loser son's attempts to feel her up while she did her duty, but her husband hadn't touched her in months. As the young man's hands went from her hair to her shoulders and then slowly but insistently down her cleavage, she hesitated.
Hundreds of miles away, another mother, this one a 40-year-old former model with brown hair and a knockout hourglass figure that made it look like she'd never given birth, let her two handsome, 20-year-old twin sons double-team her, one in her mouth and the other pounding into her wet, overheated pussy. She knew that she shouldn't let them cum inside her on a dangerous day but she was never good at telling her darling sons no, and they deserved a treat after making her cum so hard.
On the far side of the country, a 35-year-old auburn-haired woman gasped as her 19-year-old nephew fucked her doggie style on her marriage bed, her D-cups swaying back and forth in time with his thrusts. The childless woman and her husband had taken the young man in when his parents had passed away. The uncle, who was waiting impatiently in the living room, didn't like what was going on, but he had to abide by the rules, though he wished his nephew-by-marriage would use a condom, damnit! It was far too late for that, though, as the woman's stomach was already swelling slightly from the incestuous baby the young man had put into her weeks previous.
