Vibrate

A shiver ran through the probe. Lois felt it in her enlarged tunnel, the glass dildo penetrating so deep inside of her that the slightest movement could be felt right inside the core of her. The reporter focused on her breathing, waiting for the shiver to pass.

Except it didn't.

The mechanical vibration continued for a long minute, a soft purring motion that reminded Lois of her favorite vibrator on its lowest setting—but she had never jammed that elbow-deep in her own crotch. It took an effort of will to maintain position as the thing continued to buzz inside of her, and she expected her pussy would eventually go numb.

Except that didn't happen either.

Lois' swollen pussy was drooling, clear fluid running down the glass shaft, and there was a soft whine as the speed of the vibration gently picked up. She could feel everything, along the entire length of her inhumanely extended channel, cunt superhumanly sensitive as the glass shaft began to buzz faster and faster, an auditory whine of the inner motors accompanying the more powerful vibrations.

Squatting down on the fat probe, Lois balled her fingernails into her palms, trying desperately not to cry out in desperation. Her whole cunt was on fire, the swollen and sensitive birth canal pried wide and stimulated all at once, and she was absolutely aching as the stimulation brought her to the brink of climax, and held her there.

"Stimulation successful in triggering vaginal growth." The automated voice spoke aloud.

The reporter stared down. Her eyes focused on where the probe was just entering her gaping slit, stretching it to its maximum—and sure enough, she could see the labia gently creep down the length of the shaft, growing millimeter by millimeter. Before she could process the idea of her elephantine cunt growing even bigger, the voice chimed in again:

"Increasing vibration to maximum."

Lois had once tried one of those Hitachi wands, the ones with the giant vibrating knob on the end that supposedly sent women into orgasm. Her one trial had left her clit sore but happy, though the vibration was too intense for any of her normal masturbation sessions. The wand had been living in a box in her closet ever since.

The sudden vibration of the probe reminded her of that...except she had never tried to stuff the whole length of the wand up her cunt. Now she could feel the thick glass shaft inside of her pound against her vaginal walls, stretching her out, whipping back and forth inside of her. It was like her entire fuckhole was getting a deep tissue massage at the same time, and she could feel the deep vibration in her teeth, traveling along her bones.

The only thing it didn't do, ironically, was much for her clitoris. The shaft was buried too deep inside of her, and while the vibrating base was definitely stimulating in its own way, her ultra-sensitive clit was feeling neglected and **** for attention. It felt good...great even...but Lois knew she wasn't going to get off this way.

So she grit her teeth as the probe pummeled her pussy, hoping she could last until the next part of the program.
