Five tonight

Animalistic thumping and moans echoed in the ladies bathroom. The feeling of bare cock - unprotected cock - thrusting into her wet pussy, skirt flipped up, bent over, braced against a wall, and stained panties on her feet, sent sparks burning through Rose's veins. It was one sensation she firmly believed she would never grow tired of.

"Fill her up! Fill her up! Fill her up!" Tasha and Emily chanted together. The older half-sister had her back to the door, blocking it from opening, while the younger leaned against the sink. Both were touching themselves, hands caressing bare breasts and labia as they watched the erotic display with lidded eyes. Their clothes were either shoved aside on their bodies or littering the floor.

The older man, whose number and Mexican heritage Rose had learned but not his name, slapped her ass. He grunted, "You sure you want me to, girl?"

What a gentleman! He hadn't minded the creamy mess her previous four partners had left in her pussy, and now was asking her consent before adding to it! Surely, he would be a worthy sperm donor! She felt vindicated to bet the names of her and her sisters' firstborn on him.

Rose cried out as her pleasure peaked, staring lewdly at her sisters' chests, imagining them bursting to fill with breast milk - because why stop playing the game after she got knocked up, when there remained two other fertile wombs? She thrust back with ****, sheathing him fully and caressing his virile balls in lieu of answer.

"I love these games!" Roaring, the man grabbed Rose's hips and anchored himself to her. Moments later, she felt the unmistakable sensation of cum shooting inside her, each spurt painting a universe of stars in her eyes.

"Fuck yeah man! Make sure it goes deep!"

Grunting in reply, the man stayed pressed against her ass before slowly moving back and forth, diligently emptying the last drops of seed inside her. Finally, with a wet pop, he pulled out, a string of thick cum tethering to the tip of his dick.

Immediately, they were beset by her two sisters, doing their best to clean them up quickly. Tasha dropped to her knees with a practiced motion and enveloped the man's dick her mouth. Lewd noises escaped the Latino woman as she licked up sperm and her younger sister's juices with gusto.

Emily, on the other hand, dropped to her knees behind Rose. Blue eyes wide in lust, she thrust her fingers out, catching the spray bits of baby-making cum and shoving back inside her older sister's pussy. Rose moaned out in pleasure as she felt the slim fingers working inside her, increasing her chances of conceiving.

Over the course of the night, both of Rose's sisters had lost much of their inhibitions, escalating from watching to masturbating to sexually participating - though not fucking themselves. None among the three of them had complained when they had first begun to act incestuously, nor had they let any of the men know they were related -

Rose let out a gasp in shock as the fingers inside her were replaced by a French tongue.

Watching from the side, Tasha's mouth still vacuuming his dick, the Mexican man commented, "You sure have some nice friends, girl."

"Y-yeah, great f-friends!" Rose yelped as Emily's tongue flickered over her clit. Giving a loving pinch on her butt, Emily then got back up.

Looking at the man, a whimpering Rose, and a winking Tasha - who had now finished cleaning - Emily opened her mouth to show off the cum she had sucked out of her sister. Then, she closed her lips and swallowed with an audible gulp.

Rose gasped in shock. "You slutty bitch! You've reduced the chances of him knocking me up!"

In the old world, this act may have been celebrated. But times were different in the new world created out of Rose's fantasies.

"That bitch!" yelled that man in agreement. Not that he would win any prizes if he won, besides knowing she bore his children. It was the principle of the matter, truly.

Emily, who had bet on a touring Frenchman earlier, smiled innocently as she served her father's country with pride. The bathroom lights framed her as an angel. An angel of love, really, as her hard nipples and dripping pussy remained uncovered. Then she let out a yelp of surprise, as Rose thrust two fingers into her cum-filled pussy, pulled out a couple white strands, marched over to her sister, then shoved them inside of Emily's wet love-hole. Rose's other hand had pinned the elegant European's body to the wall and was now lightly **** her throat.

"This is what you get for being a cheater!" Rose shouted, a wicked grin on her face. Emily's voice began to ring out in protest, before Rose abruptly shut her up by kissing her.

It took but a moment for the two sisters to melt into each other. Almost on instinct, Rose's virile, cum-coated fingers began thrusting in and out of their warm home, Emily's legs submissively spreading open in an invitation for deeper penetration. Yet the moment was not to last, as Tasha coughed pointedly, sounding faintly jealous. They parted with deep breaths, gazing into each other's souls.

Fluttering her eyelids and thrusting out her chest, Emily said panting, "I'm sorry for cheating. And I forgive you for trying to put a baby into me just now - but only because you're a really good kisser. And amazing with your fingers."

From across the bathroom, Tasha's voice carried over to them in an impatient tone, "Enough dallying. Put on your clothes already, you spoiled babies."

10 minutes later, all three sisters were outside, calling it a night. The man had gone back to the dance floor, but not before offering to participate in any future games they hosted. In public, none discussed the lewd acts they had partaken in, though Rose would occasionally rub in stomach in thought, wondering if tonight would make it swell up. Regardless, she was satisfied.

And yet.

She wanted more! It wasn't enough to take part in a incestuous baby-making game once a month. Nor was it enough to only get bred once a year! Yet she was conflicted as she didn't want to speed up her pregnancies or change her fertility - the uncertainty and commitment was part of the fun! Rose tapped her chin with her pencil, absentmindedly summoning it and her Rulebook.

A moment later, she jumped for joy as she got her answer for a new thrill.
