The dream began on a huge underground science station, with metal walls and pale ceiling lights that flickered. We were running from something, everyone was rushing to seal the doors, but the creature couldn't be contained. I could hear the growls and wet noises it made approaching me, and then blacked out.
Next thing I know I'm laying on a puddle on the floor, my clothes soaked, and a gigantic beast crawling between my legs. The alien's body was wet and heavy, no discernable head or face, just multiple tentacles of all sizes sliding on the floor and feeling up everything in the room, including me. It was just me and the creature, I was left alone by everyone else. A thick tentacle slapped my pvssy and rubbed my crotch all over trying to force their way inside, and as much as I wanted to recoiled in fear and disgust, I was paralyzed. The monster's slimy appendage finally penetrated me, and I blacked out again.
When I came to myself, I was walking through the hallways of the science station, trying to find my way out. My legs were covered in slime and I left a trail behind me whenever I went. I remember feeling so much pleasure, stumbling and moaning, holding onto the walls, not knowing what was causing me to feel this way. And that's when I noticed: something was being jerked in and out of me as I walked. I kneel on the floor and look down to find a little creature, thick as a soda can but very soft and gooey, wiggling uncontrollably inside my pussy. I was shocked and terrified, but I couldn't stop it from squirming against my inner walls and making me contort in pleasure.
"Please," I mumbled, "I know you can hear me. Is there another one of these little creatures in me?" And the tentacle alien responded as a voice in my head, a distorted woman's voice: "Yes. They will stay inside you." I look at my crotch and I could see now, not only one, but two wiggly tails sticking out of me. Struggling to catch my breath, I say to the alien: "I need one of them in my ass. Please, I want them to get inside my assh0le too!"
The alien did not respond, but I started to feel one of the little creatures immediately crawling out and forcing itself against the resistance of my tight assh0le, my alarm rang and I woke up.
