*I gasped as it slid inside me. THis couldn't be possible. Monster's like this didn't exist. I gasped and kicked as it slid inside, the thick thing force my lips apart as little bits of my fluid slid down my thighs. My body was enjoying this. Traitorious body. And here I was outside, in the dark with the cool air playing over my nipples.*

Dendrite laughed in delight as it leaned against the window and pushed further into the girl's warm sex. "Such a delight..." Strong tendrils held her calves and thighs, supporting her, keeping her spread to display her flushed folds and flexing buttocks. "Mmmm, such a beautiful sight back here, like a pretty picture." The monster growled deeply and pulled back, then began to thrust eagerly, dribbling slime to mingle with her natural lubrication, pumping deeply in and out of her slick tunnel.

*I struggled, finding I couldn't as I gasped, feeling my thighs contract slightly as my hips moved. He was thrusting inside of me, that slimy feeling crawling down my legs partly him and partly my own body.*

(Bump)

Dendrite growled, its alien bulk filling the window and looming over the girl, staring at it. The tentacles held and supported her legs as the monster began to buck its body, pushing rhythmically against the girl, making her entire body bounce back and forth. Its phallic member pounded into her, sliding deeply into her sex, claiming her completely with its movements. More tendrils slid over her bottom, squeezing and stroking, brushing teasingly between her buttocks as well.
