Sarela's face twisted and her eyes shut as she tried to fight the pleasant sensations that the Gamorrean's thrusting was causing.  The vibrator had been pleasant, but it had been lacking... something, a living element perhaps, something that the Gamorrean, however disgusting, had.  The twin filling was a new experience to Sarela, and not all that unpleasant.  She had to fight back moans, and an occasional whimper escaped past the gag.
