You got separated from your group in a tour of a cave system, and ended up in a completely unknown part of the underground where you search for a way back to charted territory with only the light of your flashlight. You occasionally come across tunnels you have to crawl through on your hands and knees, but they’re never narrow enough to make you worry
Something lands on your head. Something slimy and squishy. You panic and try to brush it off, but it sticks to your hand now. When you point your flashlight to see, it illuminates a strange, large slug-like creature. You barely get a look at it before it slithers underneath your sleeve. You panic, dropping your flashlight as you try to pull the creature from your clothes, but to no avail as your attempts just slide off of its slimy body. It travels lower down, from your shirt to your pants. You can feel it enter into your underwear, pushing its head inside of your pussy. When you try to grab at it, it slips right through your fingers as it wiggles its way deeper. Your knees buckle as it forces a moan from you, disappearing inside of you quick and pushing into your womb. When you catch your breath, you can feel the weight of it inside you. Out of options, all you can do is press on.
But as you walk, you feel another one attach itself to your ankle, quickly worming its way up your pant leg. This one is equally as persistent as you try to stomp or shake it loose, undeterred as it presses onward. Your flashlight briefly illuminates more of them. At least a dozen, slowly making their way towards you. You have to ignore about the one already attached, rushing towards the next tunnel to crawl through and escape. On the other side, you’re only met with more wide open caverns. As you take a few steps forward, you step on something squishy causing you to slip and crash onto the ground. The slug you stepped on attached itself to your boot, now making its way up towards your entrance like the others. You scramble to try to throw it off or scrape it against the rocks around you, it barely reacts to your attempts.
In your panic, you barely notice the other slugs swarming you. By the time you notice, at least ten of them have attached themselves to crawl into your clothes. You give up on trying to get them off again, fleeing for the next tunnel. As you crawl through, you can feel them shoving themselves through your entrance to reach your womb. You pant and groan as you crawl slower this time, legs quivering as they squirm against you and each other. Your flashlight falls ahead, rolling out into the next cavern.
As you catch up, falling on your side to pick it up, you’re met with a horrifying sight. Slugs everywhere in this new cavern, all noticeably thicker and longer than the ones from before. You’re still overwhelmed, belly beginning to swell with all the slugs still entering you. You try to call for help, but your voice echoes for no one through the unexplored caverns. Slugs swarm over your body, and no amount of struggling and flailing loosens them. As the first of big ones reaches your entrance, you grunt and moan around the slimy intrusion, legs quivering as they all push against each other to get into their new home. A particularly large one pushes up against your entrance, stretching you out wider than the others as it inches deeper and deeper. It makes its way into your womb, allowing more and more to swarm and follow it. Your belly grows bigger and bigger, and it’s getting hard to tell how many are in there. Their squishy, slimy bodies squirm and roll against your insides, the pressure growing tighter and tighter.
When you find a burst of energy, you force yourself to your knees. Holding your swollen belly with one hand, already looking more than overdue, you stagger and waddle towards the tunnel with your flashlight in your other hand. Hope sparks in you as you reach it without falling, squatting down. But as you lean forward to try to crawl through, you’re stopped. Your belly is pressed against the stone beneath you, and you realize the slugs inside of you have made you too large to fit through the tunnels.
You fall back from the tunnel entrance, feeling the next huge slug wriggle deeper to join the countless others. Your belly is heavy, so heavy that you aren’t sure if you can stand up again. The strained flesh rolls and shifts with the movements of the creatures that invaded you, only growing more intense as more of them join in. You collapse into a mess of whimpers and moans, the pressure all too much to handle. And still, there’s countless more to come.
Time passes. That’s all you can describe it as, without any way to tell the time so far underground. You’re leaned back against the wall of the cave, completely exhausted and spent. The swarm of slugs has stopped, mainly because they’ve all gotten inside of you now. Your belly is unbelievably gigantic, having grown bigger than the rest of your body with the sheer volume of slugs. It gurgles and groans its complaints about the internal pressure, though there’s not much you can do about it, the sound echoing loudly through the cave. Then you feel something slimy land on your belly. It slowly crawls down the front of it, squeezing its way underneath. Despite all the weight bearing down, it moves towards its goal. Slowly, steadily, until finally it reaches your entrances and slips inside with all the others
