Imagine you just moved into a new apartment, rents cheap, but there's one condition, you're not allowed to open a single door, you're a little uneasy going to bed in your new place, but you strip off and go to sleep in your favourite pair of silk panties.
A few hours later you're roused from your sleep by a wet feeling on your leg, but your leg has gone to sleep and you can't make out what you felt anymore, you reach down to try to find what was on your leg only to find that you can't move, you always joked about sleep paralysis but you never thought you'd suffer, maybe it's just the new place.
You lay there, eyes wandering around your room looking for demons when you feel something wet on your leg again, you start freaking out you know something is there, it's wet and feels slimey and is crawling up your leg, first your ankle, then your calf, then up your thigh, you're panicking but can't do anything but lay there and hope it stops.
Before long it's climbed all the way up to your crotch, and is gently nudging against you, and that's when you realise the size of it, it's little bigger than a finger at the tip, but towards your ankle you can feel a huge mass wrapping around your leg, you strain your eyes and try to look down but even though it's huge you can't see it.
That's when it starts, at first it's gentle suction through your panties, but after a short time it's sucking in hard rhythms at your clit, your silk panties doing nothing to dull the sensation and your body not helping you as your cunt starts leaking, between the sheer terror of your situation you're not only aroused but in pleasure.
You're horrified at your reaction but it doesn't stop you from trying to force your body to move, to grind against the tentacle sucking on your clit, it feels good, so good, better than any sex you've ever had, you want more, *need* more, and that's exactly what you get, you lay there for hours blissed out with the tentacle sucking away at your clit before after countless orgasms it stops, the faintest light breaking through your window as it slithers back down your leg, you try to look for it moving but still can't move your neck, you're left needy and exhausted and soon find yourself succumbing to your exhaustion.
You wake up a few moments later and are surprised when your attempt at jumping towards the end of the bed actually works, you furiously look for where the creature came from but find no trace on the bed or the floor, but you know it was there, you grab your leg to find the slime it secreted to find nothing, your leg is a little cold in patches but nothing is on it, you find a single hard needle sticking out of your ankle like one from a nettle.
Between that, are your soaked panties you know it was there, and that's when you make up your mind to go through that door you aren't supposed to, if it's not in your room it must be in there, logical deduction, you grab a hammer and prise the nails and wooden boards off of the door.
You're stood there, all but naked save for your silk panties and a loose crop top to cover your breast so your neighbours don't see, you're breathing hard, wondering if it's too late to turn back, wondering if you should open the door, and then you feel your panties, your aching leaking cunt and decide there and then to open the door.
You throw the door open, and there's nothing, NOTHING, but how, you were going sure there was something in there, the source of all of last nights pleasure, you run in wondering if maybe your eyes are playing tricks on you and there's still nothing.
You fall down, last nights exhaustion finally catching up to you, you would cry save all your fluids are currently running down your legs from the anticipation, and then you hear a wet sucking sound above you, and you look up, there's nothing but you hear it again, you stand up and turn around, and sure enough above the door there's a huge mass of pitch black tentacles writhing there, a smile cracks on your face as you let your arms hang at your side, that's when it moves, it smothers you instantly, you can't breathe as it's envelopes you, your heart starts beating aggressively and then you can finally breathe and see again, you can't see much, it's dark, pitch black despite the light coming through the door, you can just about make out the tentacles sliding over each other.
You try to move and find yourself restrained, arms and legs wrapped with tentacles, before one starts forcing its way under your panties, the silk ripped as the huge mass forces it's way through, your clit is once again sucked on as your cunt is split open on a huge tentacle, bigger than anything you've taken before, bigger than anything you thought you'd ever be able to take.
As it forces it's way in your breasts are clamped on by two more sucking tentacles, your nipples stimulated to the point of pain but all you can feel is pleasure beyond any normal metric.
In contrast to your cunt your ass is gently teased open, the creature doing it's best to ease itself inside of you, you can feel the tentacles rubbing against each other inside you, it starts driving you crazy as you drool and moan.
You feel a tentacle brushing against your lips, careful not to go inside but making you know it's there, you start trying to lick it, to get another part of the glorious creature inside of you but it stays outside, not forcing itself inside of you, you whine and moan and beg "please please please" until it finally acknowledges your desire and forces it's way down your throat, the three tentacles thrust in and out in sync with the others.
You're blissed out of your mind, you can't think of anything but the pleasure this creature gives you, but you can think of the only way it would get better, if you could carry it's baby, if it's hot, thick meaty tentacles could impregnate your holes and make you a mother, make you it's mate.
And that's when you feel it, something forcing its way through the tentacles, something big, going through each of them, undulating inside you as the tentacles discharge their payload deep inside your holes, the one in your throat stretches your neck until you try to scream but of course you can't, you have a huge tentacle fucking your throat, it eventually passes through and you can feel the eggs taking up space in your insides, your stomach, your ass, your womb, and then you feel another set of eggs being forced through the tentacles.
This time you don't dare try to scream you're too out of it with the realisation you're going to be a mother to refuse the idea of having more babies, but in the end you wouldn't have to refuse, your world turns blacker than it already was and you pass out.
You wake up later, you don't know how long it's been, you're laid on your back supported by the mass of tentacles in a comfortable position, the only new feeling is the stinging in your nipples where two more small needles penetrate the pair of them and your now swollen stomach, your womb feels heavy as you try to move until you're pushed back down lovingly by the mass, you're carrying its babies you remember right before your cunt once again starts leaking after you remember your glorious breeding the night before?
Maybe it was the night before, you ponder it for a small while before ultimately deciding to ignore the time and instead focus on the fact it had its way with your body and you loved every second of it.
Your aching cunt starts leaking into the creature and it notices, a tentacle slides it's way up your leg and starts sucking on your clit while another slides it's way inside your needy cunt, it doesn't spread you like it did before, it pushes its way inside gently, careful not to dislodge its clutch of eggs sitting inside your womb, you lay back down and let your mind focus on the pleasure as your last conscious thoughts fade away.
