Xeno biology - A very special and high-tech strap on with an extra special surprise for Millie

You lean back in your chair waiting with anticipation as Molly groans and moans about her impending fate, while Millie eagerly listens to Yuki's explanations of what each forfeit would entail. There is a myriad of forfeits to pick from, and Elise is very eager to see other actresses get to experience them first-hand in the episodes she'll shoot after today. You're not entirely sure if the former Holo-porn star plans to remove the creamy donations you left behind, after all, there's always a market for genuine breeding smut.

In any event, you are delighted to hear what Millie settles on in the end, especially since while it does carry the chance that Molly walks away without being knocked up, it consequently carries a risk that both Millie and Molly get a womb full of your cum.

"I think I'll pick Xeno biology," Millie says with a big smile.

"Oooooh I've been dying to see someone pick that," Yuki cries out excitedly. "Now while our crew go gets you both prepared and everything set up I'll explain to the audience what's in store for Molly," Yuki says excitedly as two members of the crew help escort Molly and Millie away.

In the actual Holo-porno an edit of Yuki excitedly explaining exactly what is in store for Molly and Millie will be edited in. You were extremely happy with how the sex toy turned out. A sizeable strapon based on an accurate representation of the penis of the Canid Futara, an exotic beast from several systems away. A species which has much like humans has futas which are exceptionally skilful at mating and breeding, thanks to a couple of features to the anatomy.

Firstly the bulb which it can implant to ensure thorough inseminations, colloquially referred to by xeno-biologists as their breeder bulb. Now the Canids often mate for pleasure as well as procreating, so insertion of the bulb isn't required and often isn't by the males on the species, whereas the futas of the species nearly always attempt to. Furthermore to ensure their progeny, when futa Canids plant their bulb into a female or fellow futa Canid a secondary reservoir opens in their body allowing some of the excess seed to travel back into its own body and inseminate itself.

The strapon is capable of doing both, and with special sensors hooked up to the wearer, to allow them to feel what the cock would feel, from the tip of the cock perfect for pressing into a cervix, right down to the ache of the heavy balls, which were brimming with your cum preserved in a miniature stasis field. Millie and Molly will be made away of the breeder bulb and what it would mean if Millie sinks it in and keep it inside, but they wouldn't be aware of the self-insemination part of the toy.

As far as Millie will be aware the smaller end of the strap-on simply fits into her own sweet sex for added stimulation, while the bigger end with the bulb will be to fuck her Sister with. The added sensors will allow her to feel every inch of Molly's pussy stretching around the xeno-shaped cock. The bulb is merely there to act as a threat for Millie to hold over Molly as the ultimate payback. A very tempting opportunity to see if Millie would go even further to use her Sister to launch her own career, even if unwittingly giving herself the same 9 or so-month setback the same way her Sister would have.

You smile as you see the bed floating gently on a few suspensors glide effortlessly onto the set with Molly lying on her back her wrists secured to the bed via some restraints. Millie follows shortly behind already wearing the strap-on and stroking the life-like xeno cock attached, enjoying the sensation of it thanks to the neural feedback sensors stimulating her mind with accurate sensations of what it would feel like. You can just about make out the slight glistening of your precum already leaking from the tip and you feel your own cock twitch knowing that your precum would also be flowing into Millie's body via the attachment inside of her.

"Mmmmm this feels amazing, I never knew having a cock would feel this good," Millie giggles as she continues to run her hands over the shaft which twitches to her touch. "If it feels this good with just my hands, I can't wait to feel how good it is inside of you, Sis," Millie adds with a giggle.

"Well if you like it enough, there are toys like this you could buy, or maybe you could get yourself gene-modded into a futa," Yuki offers with a giggle.

"Very tempting," Millie muses with a big smile as she reaches down and cradles the swollen sack housing all your genetic material.

"But what about the Sorority, Sis," Molly replies shaking her head. "You know how she feels about futas," She adds in a low conspiratorial voice.

"Sis we don't need the sorority anymore, this is going to be the big break we want," Millie replies with a smile, "Besides there's a good chance we're getting kicked out anyway once this all hits the holo-net porn sites," She adds with a casual shrug.

Molly opens her mouth to protest some more but panic overtakes her when her Twin Sister climbs between her legs and begins to tease the tip of the canid cock across her slit. For all of her protesting about not wanting to fuck earlier, you can't help but notice that Molly's pussy seems very wet and eager to enjoy the experience. Part of you wonders if the act of being tied down and fucked might be a huge turn-on for her, that or she's into her Sister more than she let on.

"Void, it's so warm," Molly eventually comments while Millie teases the toy up and down the slick and increasingly wet folds of her Sister's pussy.

"So are you," Millie groans, the canid cock twitching and leaking some of your harvested precum over Molly's sweet sex. "Void, you're so wet for me," She adds with a sensual giggle. "Almost wish this toy wasn't so big now, I want to shove it inside you already," Millie adds in a low growl.

"Please, it'll tear me apart," Molly pleads, while her nipples harden as her eyes stare at the sizeable strapon.

"Don't worry, Sis," Millie begins before letting out a low groan, the Canid cock twitching and showering Molly with a fresh spray of your precum. "I'll get you nice and warmed up, so it'll only hurt a little bit," She adds reaching out and stroking her Twin Sister's face while licking her lips.

Molly whimpers in response but you can read from her body language that she's very much enjoying this on some level, some deep-seated in the far reaches of her subconscious desires were being fulfilled. This comes as some relief as you were worried that this film might have taken on a much darker tone if Molly was **** to be fucked by her Sister. Instead, you end up with a scene of her quickly succumbing to her base desires and within a few minutes of being teased is almost as eager to be fucked as Millie is to fuck.

"Quit teasing me and get this over with already," Molly mewls, although by now she's letting out soft moans of pleasure each time the Canid toy cock brushes over her swollen clit.

"Fine by me," Millie replies in a low tone, pulling her hips back and taking her time angling the large xeno cock at her Sister's sweet sex. "Mmmmm ready to be my little slut?" Millie asks in a sensual growl.

"As if you could, I bet you get so overwhelmed you cum right away," Molly replies in a teasing tone.

With that Molly doesn't reply, simply pressing her hips forward, the tip of the Canid cock pressing between the soft dewy folds of her Twin Sister's sex and slowly mounting pressure against her inner folds until the part and start slowly swallowing the strapon. Both Twins let out a loud groan of pleasure as their senses overwhelmed with pleasure. For Molly the feeling of the exotic cock stretching her wide, the shape, the contours and texture, unlike anything she's ever experienced. For Millie is the new and overwhelming sensation of having the hot wet walls of her Sister's pussy squeezing her cock. Each slight movement, each inch that sinks in floods both the twin's minds with a wave of pure pleasure.

"Fuck this feels incredible," Millie hisses in delight, the full length of the cock now sunk deep into her Twin Sister's pussy, Millie enjoying the feeling of her Sister's body reacting around the Canid strapon.

"Just don't get too carried away and forget about the bulb," Yuki offers in a sensual tease. "You only have to fuck your Sister, you don't have to breed her," She adds with a sensual giggle.

Molly lets out a groan of protest, or perhaps it's just a groan of pleasure it's hard to distinguish given her current circumstances. The sensation of her tight young fertile folds stuffed full of the Xeno cock and the slight tremors of her Sister's body sent delicious ripples of pleasure through her body. It would be understandable for anyone to momentarily forget all about the two weighty sacks gangling beneath the strapon filled to the brim with your potent baby-making seed.

You take a moment to surreptitiously check the read-out of the high-tech strap-on to see that about 30% of the precum you filled it with has now made its way into the bodies of both twins. The nanites are likely already busying themselves with making sure that should Millie find herself unable to resist the urge to breed Molly, your super sperm would have the perfect conditions to breed. Your cock twitches, in a mixture of anticipation of getting to watch it all unfold, but also with a sense of frustration that you couldn't be there in person to deliver your cum.

You lean back and consider your options on whether you take Elise up on her offer and maybe see if Yuki might be interested in making things a three-person event. You were curious to see if your modifications were as good as rumoured and to have the chance to test your seed versus some Holo-porn grade birth control. Well, that would just be more valuable data surely. In any event, you lean back in your chair and watch as Millie begins to slide the High-tech toy back out of her Twin Sister.

"Oh Sis, you're going to have to try this thing out if they'll let us," Millie groans, biting down on her bottom lip as she withdraws herself from the slick yet tight embrace of Molly's love canal. Just the thick tip of the cock remained inside the puffy red lips of Molly's hairless mons.

"I don't think I'd care if the sorority kicks us out, we can just rent out own place and play with toys like this all the time," Molly agrees, wiggling her hips at the sensation of feeling so empty now the Canid Cock had been almost removed from her hungry hole.

"You know, Sis, if we get out own place, we could even experiment with the futa mods," Millie suggests with a sensual laugh while teasing Molly with just the tip of the strap-on.

"Oh fuck," Molly groans, shuddering in pleasure from the idea. "But first things, first, I need this back inside me," She adds, hooking her legs around the back of her Sister's body and pulling her forward, forcing the huge xeno phallus to sink deep into her quivering folds.

Both Twin Sisters howl in pleasure as inch after wonderful inch of Canid cock is devoured by Molly's ravenous sex, the previously cautious Sister pulling Molly even deeper until the bulb at the base of the Strapon comes into contact with her outer lips for the first time. Even just the lightest touch from the sweet slick lips of Molly's pussy against the hyper-sensitive breeder bulb sends a tsunami of pleasure crashing through Millie's mind. Any thoughts of caution and sense washed away under the unrelenting **** of pleasure.

"Oh that was close," Molly giggles, between long hisses of pleasure as she basks in the sensation of being wonderfully full once more. "Almost got a little carried away there," She pants looking up at her Sister's face. Only rather than seeing her Sister smiling at the close call, she instead sees the primal hunger on Millie's face.

Without saying a word, Millie places hand hands on her Sister's toned thighs and pulls herself forward, the bulb pressing against the inner folds of Molly's sex for a moment. Molly in panic tries to say anything to snap her Sister out of whatever lusty haze that has come over her. However, the moment Molly opens her mouth, her words are replaced by a groan of pleasure with a slight hint of pain as the bulb stretches Molly wide before popping inside of her.

Fortunately for Molly and Millie simply inserting the bulb isn't all that's required for insemination, which comes as a great relief when the surge of unimaginable pleasure that shook Millie's entire being starts to wear off. Initially, Millie is a little surprised by the new sensations she was feeling, a primal urge to stay put, a twitching and fizzing sensation on her core. At first, Millie wants nothing more than to embrace these new pleasant feelings, but then a realisation that doing so might mean she would be done when she was just starting to really enjoy the strapon makes her decide against it.

Millie quickly begins to pull back and with an initial moment of panic when the bulb seems stuck pops free with an audible pop accompanied by some guttural groans of pleasure from Molly.

"For a minute there I thought you weren't going to pull that thing out," Molly laughs nervously through her heavy pants.

"Yeah lucky for me this thing doesn't go off when I pop this bad boy inside you," Millie replies with a wicked grin, "Which means I can do this," She hisses, thrusting her hips forwards, pressing the bulb back against her Sister's slit which parts and swallows up the thick bulb with much more ease. Molly hisses with pleasure as she feels the big Canid cock sink impossibly deep inside of her, the very tip nestling into the groove of her cervix.

"Oh fuck, be careful with that thing," Molly groans.

"I'm sure you'll get used to it," Molly replies with a giggle as she begins to pull herself free, before slipping the breeder bulb back inside of her Sister, enjoying the shockwaves of pure bliss that radiate through her body each time.

Molly can merely lie back, crying out in delight as her Sister continues to deeply fuck her, stretching her sweet pussy with every available inch of that wonderful Canid cock. She did wonder why despite how wet she was, why the bulb still feels as difficult to pull free from her sweet sex as the first time. Little did either of the Sisters know that the bulb starts to swell the nearer to orgasm Millie gets.

Millie drunk with the wonderful sensations of edging her new high-tech toy organ was unwittingly playing with fire. With each heavy thrust that pops the bulb into Molly's sensual slot and the tip of the Canid cock delivering a precum-smeared kiss to her cervix, Millie lingers just that little bit longer. The dizzying rush of feeling the urge to unleash your potent cargo deep inside her Sister's and her own fertile wombs is growing harder and harder to resist. Even Molly who knows what might be at stake should her Twin not pull out feels less and less inclined to worry and warn about the creamy consequences.

Soon the breeder bulb is considerably thicker and wider than any other part of the strapon, but as pleasurable as it feels for Millie and as tempting as it would be to throw caution to the wind and inseminate her Sibling, she move to pull out one final time. For a brief moment, it seems like you were going to have to admit defeat on this one, despite the swollen nature of the breeder bulb, Millie is slowly pulling it free from Molly's juicy pussy.

You consign yourself to having to simply hear the satisfying pop and watching Millie spray your cum harmlessly across Molly's naked body. With no pressure or heat surrounding the bulb the valve that would pump half the cum into Molly's unsuspecting body would be shut, and your only hope for breeding either twin falls to a bit of careless aiming on Millie's part.

However, just as Molly's inner lips begin to stretch and begin to lose their grip on the bulb before it pops free, Molly does the unthinkable and moves her legs up around her sister's back and locks her legs behind her. The camera drones catch the look of surprise on Millie's face as she opens her mouth to warn her Sister not to do what she was about to do. "Molly Wait," Millie cries out.

Molly's eyes shut clearly moments away from an intense orgasm, she obliviously seals both hers and her Twin Sister's fate by pulling Millie towards her, the tip of her Canid Cock pressing heavily into the entrance to her womb just as Millie loses control. The rest of Millie's warning dies out in her throat, replaced by a low and primal groan of raw pleasure. The smaller canid cock keeping the strapon attached to Millie begins to rapidly swell and vibrate, stimulating Millie's pussy as your thick potent cum is awoken from stasis and rapidly pumps into the reservoir of the strapon.

Molly cries out in ecstasy just as cum begins to pump and rocket up both ends of the Sophisticated Strapon, delivering your virile and potent payload deep inside both Sisters simultaneously. You watch the display on the screen before you, a cross-section diagram of the toy inside both Sisters cuts to two internal cameras giving you an unadulterated albeit brief view of your cum fountaining into both Molly and Millie. You feel a great sense of satisfaction knowing your plan couldn't have gone better, and you thoroughly look forward to being able to show Rosa and Stacy the finished product once Elise and her crew have edited it together.

Once the Twins were done, they begin to untangle themselves from each other and survey the creamy devastation left behind. Millie even notices a sticky glob of cum leaking down her own thigh. She quickly slips the strapon free and a rush of cum leaks free after it. "What the shit, Why didn't anyone tell me this toy would cream me too," Millie groans, spreading her legs wide and surveying her own thoroughly creamed cunt.

"The Canid Futara, or at least the futa of the species do that, weren't you paying any attention in our classes," Molly replies with a giggle.

"What, you knew?" Millie groans shaking her head. "Why didn't you tell me?" She demands.

"Firstly, I thought you already knew," Molly explains with a smile. "Secondly, I figured it'd serve you right trying to knock me up," She adds with a shrug.

"Oh fuck, well at least we can just get this taken care of I guess," Millie says shaking her head in disbelief.

"Not on this station we won't," Millie replies with a smile, "Not unless you want our parents to know what we've been up to," She adds with a shrug.

"Not according to your contracts either," Elise announces with a broad smile on her face.

"What are you talking about?" Millie replies turning to face the director by your side.

"A little cause Ira put in, just in case you tried to screw her on your appearance here today," Elise says with a calm and casual tone. "Which for the record you did," She adds with a smile. "Who's cum did you think we just filled you both with," Elise asks rhetorically "By the by, you two really should have read that contract better, since you've also waived Ira of any Paternity commitments and have to carry any children conceived to term or forfeit all your winnings," Elise says laughing and shaking her head. "She even left a message for you both," Elise offers before nodding towards you.

"Nice try trying to get one over on me," You begin to quote. "Hope you enjoy having my kids, because the only thing more incredible than my work is my sperm count," You add with a polite cough to look suitable embarrassed by the message.

"That bitch," Millie groans in frustration.

"Ehhh that's showbiz for you," Elise offers with a shrug.

"What are we going to do now?" Molly asks nervously.

"Well with what you'll both be paid today, anything you want," You reply, deciding to be the good news the twins might need at this point.

"Also given how this ended, It's safe to say Holo-wood might not be quite so receptive to you both, however, I have a few contacts in the Adult Holo biz who would be very interested in having a pair of Sisters who aren't afraid to perform together," Elise explains with a warm smile.

"I'm not sure..." Molly begins before her Sister places a hand on her shoulder.

"We'll think about it," Millie says in a confident tone.
