Try to revisit the witch

You slide down the wall, and when some level of conscious thought returns to you, you stare across the lake and can't help but think about the witch that you encountered shortly after entering this dungeon. Considering that she was the last sentient being that held a reasonable conversation without just trying to fuck you, especially considering she had warned you about what had just happened. Shakily climbing to your feet, you grab the book in one hand, and start to make your way towards the ramp on the far side of the cavern.

The dress reappears as you start your walk, but just as you're walking past the pool in the middle of the room, your leg catches on something and refuses to rise. Looking down, it almost appears as if a piece of the lake has extended outwards and grabbed on to the bottom of your foot, and as you watch it begins to rise upwards, sliding slowly and steadily up your leg.

With some difficulty, you manage to pull away from the lake, but it puts you off balance and you fall back onto the sheet of glass. It does give you a better view of your assailant, as it's pulled along with you. A pulsing mass of goo, the same shade as the lake, seems to form into the general shape of a woman, albeit one without legs or any true defining features. A wide opening appears in the front of its head-shaped area, as if a mouth curling into a grotesque smile, before it continues its steady slide up your leg, your foot already nestled deep inside its opaque body. You struggle as best you can, but only manage to get bits and pieces of the ooze stuck to your arms.

Clearly amused, the wordless face continues to warp shapes as the slime works its way up both your arms and your leg, moving directly towards your center of mass. You manage one last **** attempt, and pull your arms as far and as hard away from your leg as possible, and with a loud squelching noise, the slime splits in half, with the majority of its mass still attached to your arms. A moment of hopeful relief goes through your mind, but then both of the slime's parts begin to move again, quicker than before, and a taunting smile grows out of the upper mass.

Several seconds later, the slime's lower part reaches your groin. Sliding around and under the bottom of the dress, you let out a gasp as it inserts itself into your vagina, quickly filling every nook and cranny between the walls of your sex in the most complete way imaginable. Immediately afterward, the upper mass reaches your head, and begins to slide into your nose, mouth, and ears, initially preventing your breathing and causing several seconds of panic before it reaches down into your lungs and begins to pump air directly into your body.

The tendrils in your nose and ears reach inwards, going directly to your brain, sliding between each of the cracks, preventing the signals your brain is attempting to send, and allowing it to control it as if it was its own. A deep, lucid calm fills you as the slime tells your body that this is alright, and nothing is wrong, though something deep inside you still sends out warning signs. The slime is no longer visible on your upper half unless you open your mouth, but a small mass still protrudes from your lower body, though covered by the very end of the succubus's dress.
