High Stakes - Making a new sibling for your friend/rival

"Risky and hot, all the way," You reply with a confident smile, the thought of your good captain friend discovering about her new brother or sister filling you with confidence.

"Mmmmm," Amelia replies with a wicked smile a twinkle in her verdant eyes as she runs her soft hands over your body, her hand resting ominously over your flat stomach. "I wonder which of us will win," She adds with a sultry smile, stroking your flat stomach softly.

"Rather depends on what each of us considers winning," You reply with a smile.

"Perhaps," Amelia replies with a grin, "But your Captains bravado aside, I'm pretty sure you'd prefer only I walk out of here with a womb full of this potent cum," She adds, licking her lips slowly.

You can't help but dwell on Amelia's words for a moment, the risk her game implied was very real, you've already consumed more than enough of your own precum for your body to be more than ready to receive your own potent cargo. Thankfully any genetic issues that could arise from impregnating yourself could and would be addressed with what are now rudimentary gene treatments. You'd hardly be the first futa to impregnate themselves, although you suspect none quite in such a spectacular fashion as this.

While you are busy contemplating the possible outcome of this risky game, Amelia decides to get things underway, gesturing for her hybrid toy to get things started. Your thoughts finally disrupted when you feel the soft wet sticky heads of two tentacles pressing against your holes. Your lower lips quickly parting allowing the tentacle to slither its way inside you, causing you to moan in pleasure.

Amelia watches with glee as the second tentacle sinks into your ass, the tight muscular ring giving way as the purple tentacle slides into your tight rear. "Mmmmm, now let's get that potent cum sloshing back and forth," Amelia says with a wicked smile, watching the large bubble drain, the thick hot liquid pouring into the tentacles.

You gasp and groan as you feel the heat of your own spunk radiating through the tentacles, a shiver travelling down your spine as for a moment you feel a small sticky heat leak in your ass. Your body instinctively reacting and squeezing the tentacle in your ass more, causing a little more of the sticky heat to escape into your rear.

"Ooops, looks like we had a little spill," Amelia giggles as she watches a tiny trickle of your thick creamy cum leak around the tentacle slowly slipping in and out of your asshole. "Shame it was only your ass," She adds with a wicked smile. "Although I guess now I don't have to warn you about squeezing the tentacles too hard," Amelia coos as she climbs on top of you.

"They leak?" You ask in disbelief.

"Only if you squeeze them too hard, just try not to cum with your pussy and I'm sure you'll be fine," Amelia replies with a giggle as she slides herself over your thick throbbing length.

Then the sensation of Amelia's sweet lips gliding back and forth over your length reminds you why you're here and gets your head back into the game. All you had to do was lie back and enjoy the sensation of Amelia on your cock and not focus on the tentacle wriggling and sliding around in your juicy pussy. Something you'd quickly realise would be easier said than done.

The first few minutes or so Amelia continues to slide herself along your cock, meanwhile, the tentacles from the purple mass gently flex and caress your insides. It feels amazing and you'd love to be able to relieve this moment, albeit without the risks. Or at least the risks on your part. Your mind wanders to a deliciously wicked fantasy where you play games with Amelia with various women. They'd be in your position writhing and **** not to cum, knowing they'll be filled with your potent seed if they do.

As you revel in this fantasy for a moment, you feel your pussy squeeze around the tentacle as it brushes against your G-Spot. You feel a wave of panic for a moment, but fortunately don't feel any sweet sticky heat leaking into your fertile pussy. Letting your mind wander might prove to be more dangerous than you thought. You try and refocus your mind, focus solely on the feeling of Amelia's slick wet inviting folds gliding over your thick throbbing length.

However, almost as if reacting to your thoughts the tentacle filling your own hot wet folds swells and thickens, ridges and shapes form on the purple mass, heightening the pleasure of each of its movements. It begins to coil and unwind itself, each corkscrew motions brushing against the most sensitive parts of your pussy. The impossible movements although still not quite overwhelming were rapidly driving you wild.

"You can feel it can't you?" Amelia purrs while grinding herself against you. "Stroking your insides like nothing else, touching you in places you didn't even know you had," She continues with a grin. "Will you be able to resist its touch, I wonder," Amelia coos licking her fulls lips and stroking her own hands through her red hair.

"Can't lie, it feels pretty good," You grimace, trying your best to focus on your cock, which is currently poised right at Amelia's dripping entrance. If only you were able to thrust upwards.

"I bet," Amelia giggles. "So let's explain the rules of this little game of mine," Amelia says raising her hips just a fraction, allowing the swollen head of your cock to nestle between her divine folds. "Every minute your thick cum will flow from one end of the tentacle to the other," Amelia begins pressing back her hips just a fraction, the tip of your length kissing her inner lips. "When you cum, it cums," She explains with a smile.

To emphasise this point, you feel the tentacle in your pussy begin to swell once more, only this time there's a radiant heat with it, one which makes you shudder as you realise what it is. You feel the purple toy swell and swell within you, your sweet lips stretching wide to accommodate its inflated form, the heat growing as the tentacle does. You feel a cold chill run through you when the tentacle finally stops swelling, you can feel the tip pressing and forming itself around your cervix.

"Although with how much cum you generously donated, I believe it'll take my poor toy some time to pump it from one end to the other," Amelia explains with a chuckle. Your feel the tentacle in your molten sex begin to shrink and contract, thankfully the radiant heat of your own super sperm travels away with it, you then feel the tentacle in your ass begin to swell and heat up. "So bear in mind, that if you pop too soon, your might just end up getting a creamy surprise too," Amelia says in a cold tone.

"I think I can hold myself back," Your grunt, feeling your thickness twitch against Amelia's juicy folds as she gently grinds herself in small circles.

"Hmmm perhaps you're right," Amelia says with an evil smile. "Well there is the added risk of your pussy squeezing my toy too hard and springing a leak," Amelia ponders aloud. "But perhaps we do need to make this harder for you," She grins, licking her lips while grinding herself against your hard length. "Oh that could work," She says with a smile that chills you slightly.

"Oh?" You enquire, feeling the tentacle within you start to pump and withe again, only now noticing they had been still through the cum demonstration.

"How about some limits," Amelia says with a grin. "Let's say, no cumming in the first 20 minutes," She says with a smile.

"Easy," You reply, feeling your toes curling as the tentacle in your pussy begins to grind itself against your G-spot.

"We'll see how confident you feel about that when I do this," Amelia replies, firmly grasping your cock and slowly impaling herself on it.

You let out a loud primal growl as you feel Amelia's hot wet walls wrapped around your thick shaft, her hungry pussy swallowing inch after inch of your thick length with ease. You feel every detail of Amelia's slick channel brushing against your length, your cock making the reverse journey your friend made all those years ago. By the time you feel Amelia's soft ass come to rest against your chest, you're feeling much less confident about this game. You could already feel your balls churning and writhing, your cock twitching gently as it oozes precum into Amanda's pussy.

"Oh, fuck that feels good," Amelia groans as she rests on top of you for a moment. "How do I feel?" She asks in a dreamy tone.

"Incredible," You groan, wishing more than ever that you weren't tied down.

"Thank you," Amelia replies with a smile, leaning her body forward, her large pillowy boobs smothering your own as she brings her head level with yours. "Just try not to enjoy me too much now," She adds with a soft whisper before leaning down and kissing you on the lips.

Your mind is being assaulted with pleasure, less than a minute into the game starting, the tentacles in your pussy and ass being to move faster and harder. Your cock can't get enough of Amelia's juicy sex as it bounces up and down your length. The soft sultry whisper-like moans of pleasure escaping from Amelia's lips were driving you wild. The room-filling with a dizzying scent of arousal and sex.

You quickly lose track of time and where your cum is in the tentacles, the sheer amount of pleasure your mind has to process, making your sense dull. More than once you feel a warm trickle inside of you, making you shiver with excitement, unsure and uncaring of which tentacle the feeling came from. Any spare focus and willpower you have is spent trying to resist the urge to unload yourself deep inside of Amelia's womb, you just have to hold out.

"Mmmmm fuck, such a delicious cock," Amelia groans, slamming herself down on your length and letting out an ecstatic cry as her body quivers against you as she cums hard on your cock.

You lie back, tensing whatever you can to try and resist the siren call of Amelia's hot body furiously trying to milk your cock. You feel your cock swelling, your balls churning, the pleasure of being double penetrated by Amelia's hybrid toy almost overwhelming you. It was almost maddening trying to resist this much pleasure, but you had to, for the sake of your own ovaries.

The entire length of your rock hard cock is teased and caressed. Every inch being lovingly squeezed by the hot wet walls of Amelia's depths. It feels as if Amelia's juicy sex is trying to suck your length into her womb itself. You feel your shaft swelling and twitching, precum leaking freely into Amelia's deepest depths. All the while your wrestle to hold yourself back. The tentacles in your holes twitching and writhing against one and another as they slip in and out of you. You can feel the muscles in your body aching as they tense up, ready for the orgasm that you're desperately trying to deny it.

By the time Amelia comes down from her orgasm, she seems almost disappointed to find you hadn't popped yet. "Impressive, I was sure you wouldn't be able to hold out," Amelia says in a casual tone. "Guess I'll need to up my game a little," She adds with a wicked smile. "What to do, what to do," Amelia muses while grinding herself with your full length inside of her.

"Anything you want, as long as I get to plant my seed," You groan back, taking deep breaths in a vain attempt to regain some control over your body.

"Oh, Is that all you want? To knock up your friend's Mother?" Amelia asks in a sensual tone, your cock twitching in response. "Mmmmm naughty captain," She purrs, leaning forward and putting her head next to your ears. "Does the idea of giving my Amanda a Brother or Sister, really get you that excited?" Amelia coos softly, your cock twitching once more.

"It would be so hot," You groan, trying to prevent your mind from wandering.

"Mmmmm," Amelia purrs into your ear. "So kinky," She adds while starting to rock herself back and forth on your cock. "I have to admit, the ideas growing on me too," She adds. "Or should I say inside me?" Amelia pants into your ear.

"Yes," You groan with a big smile.

"My uniforms all bulky around my belly," Amelia says in a breathy tone. "My huge tits, swollen and leaking milk," She adds.

"Oh fuck yes," You groan, your cock twitching dangerous inside of Amelia.

"Fuck, Amanda would be so shocked," Amelia purrs. "Her own friend, breeding me," She adds, her tongue flicking over your neck.

Amelia's whispered words were driving you into a frenzy, the devious MILF playing to your baser instincts to make you forget all about her devious game until it was too late. Your mind happily picturing Amelia's sensual curvy frame nice and swollen with child, her big milky tits leaking through her top, the look of surprise on Amanda's face when she finds out. It was working all too well, your resistances were already slipping.

"Mmmmm maybe afterwards, I'll let you bring Amanda up here and watch your fuck her, watch you give me a grandchild," Amelia whispers, with a wicked grin as she can see you react. "Then make her watch you breed me again," Amelia hisses feeling your body tensing, your swollen cock lurching and throbbing deep inside of her. Amelia kisses you on the lips, before leaning back, her eyes glancing over to the cum bulge between the tentacles shift upwards towards the tentacle buried deep in your pussy. "Fucking Breed me, Claire, knock us both up," Amelia howls.

You're too far gone to resist now, even with Amelia telling you what was happening. Your body already slipping past that delicious point of no return. Your pussy quivers around the thickening purple mass, eagerly parting as your earlier thick potent load is pumped towards the tentacle tip. You feel your balls drag upwards, that sweet pressure already releasing as your cock begins to throb and pulse. Your thick potent load rushing its way up your swollen shaft, eager to erupt into Amelia's womb.

You let out an animalistic groan, that shakes your entire body as your thick throbbing cock filled with hundreds and hundreds of millions of your enhanced swimmers. You feel yourself erupt, the hot rush of your sperm erupting from your tip, striking a direct hit on Amelia's cervix and storming its way into her defenceless womb. The same womb your precum has been helping transform to ensure your sperm have all the advantages, guaranteeing pregnancy. Just as it had with your own.

Your entire body quivers, your slick walls of your juicy pussy, squeezing the purple swollen mass within it, helping the toy inject your own highly potent cum deep inside of your own womb. You let out a gasp, feeling a sticky heat filling you, deep inside your womb. Your own potent weapon turned against you. Amelia's wicked words driving you to let go, flood both her and your own wombs with your cum. You should be panicking, but you're lost in bliss. Your twin orgasms shaking you to your very foundations.

"Fucking Breed us both," Amelia howls, holding herself as deep as she could, excess seed spilling out around your shaft, the sight of tentacle unloading your own cum inside you, combined with the feeling of you filling her pussy up, cause Amelia to climax. The pair of your writhe together, until Amelia, flops forward on top of you, the pair of you panting together until Amelia regains enough energy to begin kissing you with a burning passion. While you gene-enhanced sperm swarms and swims, on the hunt for an egg to fertilise, regardless of who produces it.
