Imagine you go for a hike alone.

It's a cool summer evening and you decide to take a drive to a remote hiking trail in a valley to go get some exercise. You don your biker shorts so you're free of chub rub as well as a sports bra and a tank top before setting on your way, enjoying the breeze as it blows your hair around while you drive.
The small dirt lot where you park is completely empty, but you're pleased with that, it just meant you'd have the trail all to yourself and you wouldn't need to worry about anyone else.
And you were right, sorta.
Dusk begins to settle when you hear a small rustle in the woods to the side of the path. It's dense trees and hard to see, so you just chalk it up to small critters and keep going. Eventually you come to a small clearing on the trail and you elect to stop for a drink of water. You're lost in thought when something brushes against your bare calf. Before you can even finish looking down, something has grabbed you around the waist and begins to pull you back to the tree line.
You scream and fight, reaching at whatever is holding you, only to discover that instead of some crazy person, there's light purple tentacles around you. They have darker splotches, and seem to emit a dim glow. More appear from the darkness as you look around, and they all start to grab at your limbs, carrying you off into the darkness.
Shaking in fear, you're quickly completely restrained as you are drown closer to a large central mass that the tentacles are coming from. it's huge, dwarfing your structure easily and nearly as wide to boot.
"No.. no!" you yelp, as the warm 'arms' of this creature rip your clothes off and hold you suspended in the air. They start to wander over your body, some innocently exploring your face, and others...
Others are teasing at your nipples, beginning to tub at them and squeeze. another ventures across the curve of your ass, before gently poking at your asshole. You clench down in fear and it withdraws momentarily before sneaking higher and skirting over your pussy. Your legs shake as you try to close them, but the tentacles hold firm.
One of them goes for your mouth, but this one seems different than the others. Its tip is rounded and dark, as as it closes in you notice it seems to be oozing some sort of dark liquid. You try to fight it off, twisting your head side to side, but more tentacles hold you firm and it's not long before it forces its way into your mouth.
The liquid is sour at first, but as it begins to leak down your throat, you find it tastes... Sweeter and sweeter, until you shamefully start to suck at the tentacle cock it throat fucks you with. Soon you realize that the pointy ended tentacles have used your distraction to hone in on your vulnerable cunt, and they rub over your clit eagerly.
A larger one starts to enter your pussy hole, teasing and edging in, before another joins and together they start to thrust into you deeply. Filling you, but not enough to please the growing warmth in your belly. You squirm and move your hips, unable to deny how horny the actions of this monster make you.
You clench around them with a small orgasm that leaves you wanting more, but then a larger, much larger tentacle cock similar to the one slowly fucking your mouth appears between your thighs. Pre cum dribbles from its tip, and the two in your hole withdraw as it takes their place.
Muffled pleas for help are garbled on the cock in your mouth, and you moan pitifully as the huge tentacle cock begins to stretch your tiny cunt open. Tears leak from your eyes as the beast holds you still. Any attempts to free yourself are plainly futile.
The head pops in, making way for several inches of purple tentacle to follow, and your eyes are wide with horror as you watch them disappear inside you quickly. Your pussy clenches down as the sensation of being fucked open overwhelms you. You realize that the soaked tentacles which had prepared your cunt have now retreated to your only unoccupied hole.
They tease and push against you, teasing the waters as your mind is flooded by whatever it is in the cum of this monster that's making you feel so tingly and hot. When they realize you offer no true fight, they waste no time and the first one, still soaked by your cunt, spears into your tight little ass.
It burns briefly before the small tentacles on your nipples start to play with you even more intently, and your mind is sated by pleasure again. The other tentacle joins its friend in filling your ass, and you're so stuffed you can't believe your mind.
Moaning loudly, you roll your hips to meet its thrusts, soaking in the feeling of its warm precum squirting inside you before it suddenly pulls free, and you almost sob in dismay.
To your arousal stained horror, the tentacles in your ass also leave your body and the tentacle cock descends to your shuddering ass. Your legs are pulled up towards your ears, and spread as far apart as they can go as it nudges against your puckered hole. Your head shakes with renewed vigor, but nothing can stop the cock as it pushes into you.
It spreads you open in a way you didn't know possible, and your eyes are rolled so far into the back of your head you don't see the new cock coming for your pussy until it's already slipping it's fat head into your hole. You look and almost faint at the sight, it's got to be twice the size of the previous one.
The third tentacle cock fucks into you slowly, your hole straining against it but also sucking it back in whenever it pulls away. You're lost to the sensation of your little holes being stretched beyond what should be humanly possible when all three begin to speed up. Dimly you realize that the two cocks have made a notable bump in your squishy stomach. The sight makes you cum so hard you see stars.
It fucks you for what feels like hours, and you orgasm more than you can count. Eventually the monster lets out some sort of rumble that takes you from your fucked out state and brings you a small amount of awareness.
What you realize makes you squirm again, twisting against your living bonds. You want to beg, whether to be freed or for more you're not sure. Numerous lumps in the tentacle cocks in your pussy and ass seem to rush toward you, and you moan pitifully against the one in your mouth.
Thrusting faster as it cums, the three tentacles bury themselves as far inside you as possible. Hips bucking as you cum too, the one in your pussy seems to change in that instant, narrowing and sinking itself inside your cervix.
You scream around the one in your throat, blacking out momentarily but coming back to the feeling of the first egg as it strains against your pussy hole. The ones going to your ass get stuck too, but it's the one pushing against your cunt that pops in first. You shake and tremble as they force their way inside your little body, doing unknown things to your cervix and filling your womb.
Their transition to your body is made easier by the tentacle monsters cum as it floods into you as well. Warming you, relaxing you. The eggs softly plop together, rolling around in your womb and ass, making room for the ones that follow. This seems to go on forever, and you watch your belly stretch and expand, growing bigger and rounder as the eggs fill you beyond measure.
Even after the eggs run out, and your slightly bumpy belly blocks the view of the cocks in your body, they still thrust idly into you, random spurts of cum making your eyes roll back and your body tighten with another weak orgasm.
It continues forever, into darkness, where the only light is the stars above you and the glowing purple being that owns your body and soul.
You apparently doze, waking near morning. The cock in your throat, while eggless, still pumps cum directly into your stomach at seemingly random intervals.
Undoubtedly a nutrient source for the mother.
