The first one leaks the rest disintegrate and your Sister has to get creative to not get caught in the act

Oblivious to the games your Younger Sister is preparing to play with your body, you continue to doze peacefully, until you slowly wake to a pressure on your body. You blink a few times and the blurry shape of Lyra straddling your lower body comes into view, a big grin on her face as she waves a fresh box of condoms at you. You can't help but smile seeing just how eager your Sister is to get back to the fun you enjoyed yesterday and the more you wake, the more you realise that your body is just as eager as your Sister is.

"Good morning," You half mumble still feeling a little weary from waking up and a little from all the energy you exerted yesterday with your Sister. "Is that a banana in your pants or are you happy to see me?" You ask in a teasing tone.

"Take a wild guess," Lyra replies with a grin.

"Shame, if it was a banana I could at least have something to eat," You reply with a giggle.

"Oh you can eat it if you want," Lyra replies with a smile. "Not sure it's the flavour you're craving, but I guarantee everyone I know who's tried it has left with a smile on their face," Lyra replies smoothly.

"Tempting, but your Big Sis is going to need something in her body that will give her energy, not leave her ecstatic and exhausted," You reply, hoping you might persuade your younger Sister to at the very least let you get some coffee.

"Interesting point, but counterpoint," Lyra replies with a giggle, before diving beneath the blankets and quickly crawling between your legs, her tongue burying itself between your lower lips before you can even reply.

"Ughhh, no fair," You complain, between moans of pleasure, your younger Sister's tongue seemingly as good at eating pussy as she is with her words.

Lyra being the skilful menace that she is, eagerly devours your pussy, lapping up the sweet juices flowing from you like its finest wine. Her tongue probes between your folds, flicking and gliding over your throbbing clit sending wave after wave of pleasure flooding through your body, but frustratingly pulling back just as your orgasm starts to build. You claw at the sheets beneath your thighs squeezing against your Sister's head as she keeps teasing you with her tongue.

"Fuck, stop teasing me and let me cum," You groan your moans a mix of pleasure and frustration.

"That depends, can we fuck before breakfast?" Lyra asks in a teasing tone, her hot breath washing over your clit, now painfully swollen with how close you've been kept to cumming.

"Yes, just please, I can't take this," You groan.

Lyra doesn't even wait for a reply, diving back between your legs her lips wrapping around your click folds as she sucks and licks your swollen love nub, until your cry out in pleasure. Your entire body shakes as you finally climax, your Sister sliding her face further down your sex, her eager mouth swallowing all the sweet nectar leaking from your pussy.

Before you even come down from your orgasm, Lyra scoops you up and carries your quivering form in her surprisingly strong arms into her room, stopping briefly to start the cameras and other recording equipment before lowering you onto the bed. You lie back on the crumpled sheets, the faint stale scent of sex from the day before still lingers in the air, although in your aroused state the scent gets you excited, reminding you of what was soon to come. You look up at your Younger Sister as she shed her clothes, revealing her rock-hard cock in all its majesty.

"Don't suppose I can convince you to skip the condom?" Lyra asks with a sly smile.

"Might have done if you hadn't made me skip breakfast," You reply with a smile. "But I suppose we'll never know now," You add, sticking your tongue out at your Sister.

"Can't blame a girl for trying," Lyra replies with a giggle as she tears open the square foil and quickly unrolls the thin latex layer down her thick shaft.

"Sure, just trying to convince your Sister to let you fuck her bareback," You reply shaking your head.

"What don't you trust me to pull out?" Lyra replies crawling onto the bed, her cock pointing straight towards you.

"Do you trust you, to pull out?" You reply with a grin.

"Maybe," Lyra replies with a nervous smile as she shuffles towards you until she kneels between your legs, her condom-clad cock inches away from your sweet sex.

"Maybe?!?!" You scoff. "Maybe you'll be able to resist inseminating and possibly knocking up your big Sister?" You add shaking your head and laughing, although that last part lingers in your head a little longer than you'd care to admit.

"I dunno, I think you'd make a sexy mommy," Lyra replies with a giggle, moving closer until the tip of her cock teases against the wet folds of your pussy. "Just thinking about your huge titties getting even bigger," She adds in a teasing tone.

"Shut up," You groan, playfully shoving your Sister.

"Plus the fact we're related and it being so wrong, makes it so fucking hot," Lyra adds in a sensual tone as the crown of her cock finds the sweet spot of your inner folds and sinks forward an inch, her cock parting your walls effortlessly. "Don't you agree Sis?" Lyra asks teasing as she continues her slow plunge into your juicy pussy.

"Yessss!!!!" You hiss in pleasure, although in a deep dark recess in your mind, the mental pictures of your Sister flooding your pussy with her cum, and your body swollen with pregnancy get an illicit thrill you can't deny.

Lyra grins to herself, proud of how much pleasure she can provide you and excited that in your pleasure-drunk state, you didn't even attempt to refute her. Perhaps the end stages of Project Fruits might not be as hard a task as she thought it might be. Still all that fun aside, Lyra pushes the thoughts out of her mind for now, instead focusing on the pleasure of feeling your body squeezing her cock. A tiny part of her wondered just how well this first condom would hold up and how many condoms would she get through before they start to split and she gets to feel the sweet embrace of your pussy. Just imagining the sweet wet sensation of skin-on-skin contact with your most intimate parts makes her cock twitch in anticipation.

The minutes bleed and blend together as Lyra begins to thrust and pound away at your sweet sex, the waves of pleasure crashing against your mind further eroding the rational reservations your brain tries in vain to cling to. You simply lie back and howl in the taboo delight of it all as your younger Sister fucks you through one orgasm to the next with her majestic futa cock.

Lyra lets out a loud groan of pleasure as your body finally overwhelms her and makes her cum. You feel her cock throb and pulse deep inside of you, the cum so thick and potent you can swear you can almost feel the heat and stickiness through the condom. Little do you know the tiny pinprick hole Lyra had poked into the condom was wider now. Not wide enough for all her thick potent cum to seep out and into your unprotected depths, but enough for some to permeate through the protection.

Lyra's eyes widen in delight when she pulls her cock free and sees the bead of pearlescent fluid bubbling out of the hole. Sadly the hole hadn't been dead in the centre so a lot of the cum was still captured into the condom, but the small leak still delights your Sister as she quickly turns away to hide her deception and the leaky condom from you. Your sister held up the condom to the camera to ensure they could see her handiwork and the evil smile on her face.

The thought of the swimmers now freely making their way into your womb drives your younger Sister wild, her cock rapidly swelling back to full hardness as slips on the second condom. You scarcely register the change before feeling your Sister's cock sliding back into your hot wet folds, once again stretching your deliciously around her mighty shaft. You mumble and moan in pure delight, revelling in every moment of the forbidden pleasure as Lyra begins to settle back into a steady rhythm.

Lyra eagerly thrusts away at your sweet folds, enjoying each squeak and squeal of delight that escapes from your lips, her mind wandering to forbidden fantasies which she hopes to soon make a reality. The thought of her cum leaking into your defenceless pussy drives your Younger Sister to thrust harder and faster, which only makes you cum that much harder. Lyra catches herself getting over-excited her thrusting too erratic and wild, the sweet heat and pressure in her core bubbling up too quickly.

Lyra decides to slow her pace, not wanting to get you too sore before she has a chance to work her way up to the condoms with a much better chance of splitting. However, just as she makes that conscious decision, there's a sudden warmth and wetness that surrounds her twitching cock as the twin holes in the condom put just enough strain on the sheath to cause it to fail. Fortunately for Lyra, you're too lost in pleasure to notice any change in sensation, however unfortunately for her the sudden sensation of going from condom to raw sex mid-thrust is too much to handle.

The swollen crown of Lyra's cock lurches deep inside of your pussy, and a fresh thick rope of your Sister's thick potent futa seeds erupts forth and splatters against your cervix. The meaning of this sensation and the consequences are lost to the sheer pleasure they cause. To your lust-addled mind, the warm sticky sensation filling your deepest depths feels far too incredible to be anything to worry about. The tens of millions of your Sister's potent swimmers now freely making their way into your womb is the last thing on your mind with the sheer ecstatic joy of your mutual orgasm with your Sister.

By the time Lyra comes down from her intense orgasm, your body and hers working well to ensure not a single drop of her cum goes to waste, Lyra realises two things. Firstly she needs to keep you horny and delirious with pleasure until she can slip free and hide the remains of the condom. Secondly that after that there is no way she can go back to using protection, the sensation of cumming deep inside of her Big Sister is far too good to resist. Knowing these two things, Lyra quickly comes up with an idea of how to enjoy the rest of the day and just how to end it.

There are four more condoms to work through, each weaker than the last, so Lyra decides to get a little creative with how she uses them. The third condom she slips on, rolling you onto your front as she takes you from behind, the condom splitting in just a few strokes. This time Lyra is able to enjoy the sensation of your pussy without any barriers between you and her for much longer. You howl and moan in sheer pleasure as she fucks you roughly from behind, stuck in a seemingly endless cycle of pleasure. When Lyra cums, she unloads the first few ropes deep inside your pussy, before tensing her muscles and pulling out relaxing them when she's free and shooting the last of her load across your back.

The next condom is slid on after a short break where you finally get your breakfast and something to drink to replenish all the fluids your Sister caused you to lose. This time Lyra has you mount her cock, bouncing up and down on her lap, you don't even get a chance to notice a change in sensation as the condom split as you sink down on it. You enjoy just how deep Lyra's cock reaches as you bounce up and down on her shaft, stopping occasionally to grind yourself against your younger Sister's body.

For a moment you worry that you're riding your Younger Sister too hard as you watch her bite down on her lower lip, while her cock twitches and throbs. For a moment you wonder if she might be cumming, but just as you're about to ask, Lyra begins to buck and thrust her hips upwards and you pay no attention to it, especially as about 5 minutes later she pushes you onto your back and covers your stomach with her cum. Her movements are so fast that you fail to notice the remnants of the condom at the base of her cock.

The penultimate piece of protection is put on your Sister's cock, but is discarded for being too dirty to use after a quickly aborted attempt at trying to slide her cock into your ass. After apologising to you profusely, Lyra slides the final condom of the ones she poked holes in and asks you to lie on your back with your legs raised up. You're a little unsure about this, until Lyra gets into position, hooking your legs around her arms as she helps push them back while climbing on top of you.

The position leaves you feeling quite open and exposed to Lyra, yet it is also strangely intimate as you find yourself unable to look anywhere over than up into her eyes as she gazes down at you. You might have thought differently if you knew the name of this position, the mating press, but blissfully unaware you find your heart racing slightly as your Sister slides her cock into position and lowers herself down into you.

You thought you wouldn't be able to feel your Sister's cock any deeper inside you than when you were riding her, but somehow at this angle, she's able to fill you completely, almost like two pieces of a puzzle perfectly connecting. You feel so overwhelmed fully, the thick head of your Sister's cock pressing against the entrance to your womb each time she bottoms out. You reach up and put your arms around your Sister's body, enjoying the feeling of her closeness as she slowly fucks you at a much slower and tender pace than the previous four rounds.

Something about this position is magical, the depth and angle Lyra can reach, the closeness of her body against yours, the slower more loving pace or perhaps even just being able to look your Sister in the eye as she fucks you so completely. You're unsure of which, all you know is you feel a stirring in your core, other than the sheer wave after unrelenting wave of pleasure. Without thinking you slide a hand up your Sister's back and onto the back of her head gently encouraging her to move it closer. Before you can even fully process what you're doing you find your lips entwined with your Sister's tongue and your own mingling and dancing together.

Lyra is caught off guard by this sudden change, almost as much as it came as a shock to your finding yourself instinctively doing it. Yet neither of you hesitate, kissing each other passionately, like true lovers, not just people simply enjoying the carnal affections of one another. Suddenly every touch, from the smallest caress to the sensation of Lyra's cock thrusting into your slick channel, carries an almost electric current to it, heightening everything. Any last hesitations or feelings that this was wrong evaporate as suddenly you feel like this is exactly where you should be, and this is exactly what you should be doing.

The pair of you kiss passionately, stopping only to let out moans of pleasure and whisper sweet nothings to each other. In this moment the world, which to you felt like an empty and miserable place for so long, suddenly feels peaceful and perfect. You bask in the sheer pleasure of it all, the sensation of your Sister gently fucking you, the warmth and comfort of her body pressing against yours. You feel yourself close to cumming and your wrap your legs around Lyra's back holding yourself tightly against her as your body shakes and quivers as pure bliss washes over you. Lyra shortly follows your lead as your sweet velvety walls tighten around her shaft.

You hear your Younger Sister let out a loud and long groan of pleasure as her cock begins to throb and pulse deep inside of you, a warm sticky sensation spreading in your deepest depths. Lyra's cock presses right against your cervix as it pumps all the cum your Sister's aching balls can produce straight into your womb. You don't quite make sense of these sensations, at least not yet, but soon once things calm down, Lyra will come clean about this condom's failure. The rest will be her dirty little secrets, but for the moment she simply hugs you tightly enjoying the feeling of your body pressing against hers. Lyra hadn't planned on the kissing, but it's certainly a nice bonus as she feels the same fluttering in her stomach as you do.

Her wild plan only got as far as seducing and possibly impregnating you, never in Lyra's wildest imagination did she picture anything deeper growing between the pair of you. Seducing you alone was already a tall order, let alone somehow convincing you to throw caution to the wind and get into a position where Lyra could possibly knock you up. Yet as the pair of you lie together panting heavily and basking in the glorious afterglow of sex, Lyra can't ignore a new deeper yearning for you. One that makes her worry about how you'll react to finding out you're full of her thick potent futa cum.
