A Pumpkin cream-pie

Resistance is now a fading memory, the vines have you splayed out obscenely, wildly violating your tender flesh. The alien appendages show no pity, forcing themselves deeper with every thrust. With a sickening pop, you can feel the precise moment that your cervix is penetrated, the veiny vine now planted deeper than you ever thought possible. With that last act of conquest, your resolve is broken, and your body surrenders to bliss.

You shiver in their grasp as climax tears through you, your cries of ecstasy choked back by the tentacle lodged down your throat. The horrible things take that as their queue, and begin to vibrate powerfully inside of you, swelling even larger before erupting with twins rivers of thick fluid. The substance feels unusually gooey, but you pay little mind, as you're just trying not to drown as what feels like a gallon of alien seed is pumped down your gullet, while your womb gets the very same treatment.

By the time the flow slows to a trickle, your stomach is bloated with the strange stuff, making you appear a few months pregnant already. Finally, the vines cease altogether, and slowly withdraw from your ruined holes, allowing that strong smelling concoction to pour free. Instinctively, you cough as much of the stuff up as you can, until at last you can gasp for breath. It appears to be a thick green bile, and there are several small things inside of it. Could they be seeds?

Being a woman of science, the prospect should horrify you, but after such an ordeal, you feel exhausted. And besides, you can't go anywhere with green sludge oozing from your battered body anyway. Though you fight for consciousness, you eventually fall prey to the inevitable, and your eyes sink shut, your mind still trying to catch up with what you've just endured.
