A cliche

Slowly the cock descended further. Jessica, hypnotized by the cock head, seemingly unfurling even further and drawn to her damped lips. Abruptly the Snatcher stood and walked around her, leaving the bag on her, its silent steps breaking her mania, bringing panic back into her mind.
Jessica struggled against the bag, Jessica's mind avoided dwelling on what was in the bag, as wet lukewarm fluid seeped from it onto her skin, and the held meaty lumps didn't give her any ground.
The Snatcher let out another inhuman howl, though Jessica couldn't see it, she knew it was on the other end of the bag. The bag lurched, and she felt pressure through the bag as the Snatcher's unnatural strength rolled the bag off her legs and hips and over her torso and head.
Claustrophobia kicked in, and she kicked and thrashed, but her struggles were short lived as cold fingers grasped her inner thighs and pulled away at her clothes.
Despite herself, Jessica felt a trickle of heat in her core. Sure enough, she felt the blunt pressure of a cock line up with her cunt. Oddly, the cock wasn't warm at all. Nearly chilly. The tip pressed against her slit. She was dry, so her lips didn't give easily. There was cold wet pump, and the cock splattered fluid against her slit. The cock slipped a little deeper. The cock throbbed again, slowly, and another splash of cold fluid, and the flared cockhead pushed all the way into her. Jessica moaned, as her box was stretched, not entirely unpleasantly as it held there. Occasionally throbbing and dousing more of her womb with it's essence. Jessica flexed her legs, but the legs were held in a vice by the Snatcher.
With agonizing slowness, the cock slid out to the head. She could wetness run down her cheeks. Another throb. She heard an inhuman scream again, seeming to come from everywhere, and the Snatcher pushed to full depth once again, all the while pumping more of its ball-juice. And thus her fucking began.

Thrust. Throb. Pump.

Thrust. Throb. Pump.

Thrust. Throb. Pump.
Jessica found herself rocking with the thrusts, the juices spreading into a pool at her hips. Jessica found herself numbing to the **** of the thrusts, and increasingly unable to ignore the erotic friction. Her heavy blindfold giving her little option to turn her attention elsewhere.
Another inhuman scream, and Jessica felt her body pulled by unseen forces deeper onto the cock, and an electric trickle of arousal **** its way through the cock tip, blossoming into a wave of pleasure, ripping its way through her body.
The pumping doubled, and unable to control the rate of the fucking, Jessica was at the whims of the Snatcher. Finally, a strangely human gurgle, and she felt a warm splash into her cunt. Gentle. The cock twitched endlessly, one, two, three times. And the snatcher seemed to remove itself from her thighs.

And before Jessica could react further, the Snatched dragged the bag off of her before shoving her flushed body into it.

Jessica passed out immediately, her apparently poor constitution dropping out from beneath her when faced with the scents of the bag.
