You endure for far too long

The viscous fluid covers your head and fills your lungs. As you convulse in a drowning agony you briefly hope this will be the end and yet it is not. You continue to live, somehow deriving your breath from the foul secretion that packs your lungs and fills your belly whenever you swallow.

You have a very long time to become intimately familiar with your torment. The parasites - you come to thing of them as leeches, though they do not look leeches - latch to your flesh and squirm against you. They do not seem to be drinking your blood, but they become engorged on something, perhaps your suffering itself. Sometimes they seem to find any bare patch of your skin and bite into it, other times they seem to seek out parts of your body, latching over your nipples, your clit and wriggling inside your holes.

The sickening sensations of their writhing can grow into pleasure. It is in those moments that you hate your prison the most. When you feel their boneless wriggling against your clit or packing your sex and you convulse with pleasure. When cries of ecstasy bubble out from your lips and your body squeezes around these unwholesome invaders. The pleasure of such an orgasm goes on and on, until it becomes a new sort of pain and you writhe in the clutches of its agony.

Hours of torment become days. Days become weeks. You lose all track of time as your body seems to weaken and madness creeps into your thoughts. You sleep sometimes and sometimes awaken to a pustule emptied of the leeches. You can twist and wriggle a bit in your imprisoning blister, even glimpse your surroundings. The impenetrable sphincter you entered, the dim bulbs of other prisoners in the centipede's body, and sometimes the world beyond. It is not always lulling movement or restful sleep. Sometimes you feel violent convulsions as the centipede does battle with various other travelers in this nightmare realm. Huge things. Terrible things even more vile.

You begin to hear voices. At first they are too quiet to understand them, but then you begin to realize they are calling your name and beckoning for you to join them. It is warm and dark where they are, deep inside the centipede. All you have to do is close your eyes and you will join them. You feel your strength ebbing each day you are trapped. Your will to resist fades. Your orgasms of pleasure come quickly and the leeches that suckle on your body's unknown secretions grow fat quickly.

The final dissolution begins without effort. You simply begin to slip away. Your limbs stop working and darkness closes in hour by hour. The parasites empty from the blister, leaving you alone and drained of your vital ****. The voices are so loud now. A din of sighs and shouts calling to you. With a last bubbling gasp, your body heaves and you slip away, into that fathomless deep well within the creature's body.

Some time later, the bubble ruptures, fluid draining out as your hollow remains tumble into the wasteland.
