Futa Breeding Orgy, with a Prize to the whoever has the most trophies

Samantha can hardly contain her excitement when you both arrive at the party, wearing your matching costumes concealed beneath an unassuming coat. The costumes sold as slutty cultist robes were supposedly fairly accurate to what Mira cult priestesses wore back in the old Earth days, denying the fancy dress shop from placing the much sought-after slutty adjective before the costume name. The robes were a sheer white fabric with more opaque pink patches covering your crotch region to merely hint at what someone might have between their legs, or at least just how well-gifted you might be.

"I wonder how they managed to pull this off?" Samantha says, checking the holo invite once more and running her eyes over the words Futa Orgy.

"Dangle the option of free and easy sex and it's a surefire way to find out how many Futas you have in any population," You reply with a smile.

"They're not all that sex-crazed, are they?" Samantha asks

"You've been one how long, and how many of your course mates have you fucked and potentially bred?" You reply with a smile. "Joking aside, you're quite right not all futas are sex mad, but there are many rumours about how insatiable we are, and well where there's smoke, they're usually a catastrophic combustion event and all that," You continue with a smile.

Thankfully the security to get into the part was entirely autonomous, all the better to keep the anonymity of the guests, thankfully Stacy had already hacked your invite to make it seem to the systems that it was for two people. You slip inside the building without issue, following the signs for the party although when you finally reach a set of double doors. Outside stands a red-haired woman standing completely naked except for a gold Venetian mask, her lips clad in gold lipstick curl into a smile when she sees you both.

"Welcome, please place any coats and valuables into one of the lockers, then put on one of the bracelets provided and follow me, the festivities will be starting shortly," The masked woman says with a smile, gesturing to the lockers to her side.

"Are you part of those festivities?" Samantha asks with a grin.

"Myself and the rest of the staff, are available for your pleasure, but only the guests will count towards the prize," The masked woman replies with a soft tone.

"A prize as well as an orgy," Samantha muses with a coy smile.

"I'm guessing the game we play, is tracked via the bracelets?" You ask with a wry smile, as you slip the device over

"Indeed they are," The masked woman replies, "The rules shall be explained once all the guests have arrived," The masked woman explains with a polite smile, before gesturing for you both to follow her.

The pair of you follow the masked woman, enjoying the sight of her soft ass jiggling with each step as she leads you through the large double doors and through a short corridor which opens into a well-lit space with clusters of people dressed in similar attire as yourselves. A number of naked women can be seen carrying trays of drinks wearing the same gold masks. Most of the guests were chatting while others were merely observing the room, a nervous yet excited buzz filling the room.

"So where might I find you, once the guests have arrived?" Samantha asks your redhaired guide with a hungry smile

"I'll be right here by the entrance should you need me or want to give me a tip," The redhead replies with a giggle.

"Oh count on much more than just the tip, Red," Samantha purrs with a wry smile.

"I look forward to it," The redhead replies, before giving a nod and slinking back to the entrance ready to meet and greet the last few guests.

A few minutes pass while you and Samantha look around the room, seeing the various piles of cushions and furniture spread throughout the large open space, some out in the open while others tucked away in nooks for those seeking a modicum of privacy for the hedonistic delights. You also make a rough head count of about 100 or so party guests, by the time the lights begin to dim and a spotlight shines on two balcony areas.

"Thanks, you all for coming tonight to celebrate my Birthday in style," The familiar voice of Professor Usella calls out, cutting the low buzz of people talking as the room turns to face one balcony or the other, the sound terminating from both as both twins are stood speaking simultaneously.

"So there are two of them," Samantha mutters quietly to you.

"You didn't believe me?" You reply in a sensual whisper.

"I had doubts, but I wasn't going to let that get in the way of attending an orgy," Samantha whispers back as the twins continue to draw out their introduction of the evening.

"Now as I'm sure you're all aware the theme is rather special as we're going to have a few wonderful guests which for many of you will be a first-time experiencing the joys of a futa lover." The twins announce, with some cheers and whistles from the partygoers. "However, we've been a little naughty and there's a second surprise," The twins continue.

"Oh, you might want to pay attention to this bit," You whisper to Samantha who is looking back hungrily at the spot where the red-head attendant said she'd be stood.

"Some of you who know of the cult of Mira might already have guessed, but for our less illuminated guests, the second component to tonight's orgy will be breeding," The Twins announce eliciting a few gasps of surprise. "Now nothing is guaranteed, but we wanted to allow you all to experience the illicit rush of potentially being bred," The twins continue, the partygoers continue to murmur. "To enhance that thrill the only protection we're allowing tonight are these condoms we've provided, most of which should function as expected," The twins continue with a wicked laugh. "But some will fail and leave you with a hot sticky surprise with nothing but nature to decide if that surprise will grow," The Twins conclude, the murmuring amongst the partygoers increases.

"A little annoying there's only a chance," Samantha whispers with a shrug. "Maybe I can lend a helping hand to even the odds in my favour," She adds in another whisper.

"No need, the mods we have, the nanites in the precum bypassed most birth control, condoms included," You reply in a soft sensual whisper.

"Fuck I love these mods," Samantha whispers back, while the twins wait for the partygoers to settle.

"Now of course, we're not forcing anyone into anything, what you do once you leave our party is up to you," The twins begin. "There are generous grants to those who do walk out of here with a little gift from the Goddess Mira, thanks to the Colony Populations board," They continue. "Equally there are many options for those who aren't so ready to experience the joys of motherhood, just yet," The twins explain, which seems to get the room to quiet down. "We only ask that while you're at the party, you just allow yourself to be swept away in the moment of passion with a futa," The twins conclude, giving the partygoers a few moments to absorb the information.

"And here's what I'm waiting for," You mutter to yourself.

"Now to give you all a helping hand here, we have a special prize for the futa with the best luck with flooding the most wombs with their seed, and to the guest who pushed their luck the most by fucking as many partners as possible," The Twins explain. "Both will be able to request anything from me by the end of the night and don't worry those little bracelets will keep track of everything for you," The Twins continue. "Now then, with all the rules explained, let the festivities begin,"
