Moonstone Convinces Sue Storm To Protect Her

As soon as the door to Dr. Stone's office closed, the blonde was on her. Fingers slipping beneath the lapels of the Invisible Woman's jacket and pulling it down over her arms. Undressing the heroine with her eyes even as she helped pull her clothes off. Sue could hardly take in what Dr. Stone was wearing: two-inch black heels, a black latex microskirt, and a sleeveless corset that bared arms, midriff, and a lot of cleavage.

"Come on," Dr. Stone said. "We're going for another little walk. I want to show you my favorite place in the whole city...and you're my invisible bodyguard. So guard my body!"

Sue Storm gulped. She knew this was insane. But she saw Dr. Stone silhouetted against the window, and her whole body seemed limned with a golden glow that made all of Sue's protests leak out of her head...and her thighs quiver, pussy suddenly wet. Something that Dr. Stone checked as soon as Sue's panties came off, two fingers sliding between the Invisible Woman's thighs, up and in.

The psychiatrist licked her fingers with a lurid leer as Sue folded her clothes and put them in a large bag. She allowed Dr. Stone to slip the collar with the leash around her neck.

"Go invisible," Dr. Stone ordered. "And keep a close watch. I don't want anyone to touch me."

Sue did. The psychiatrist grabbed the clothes-bag, opened the door and tugged gently. Sue closed it behind her.

Down the hallway. Down the elevator. Out into the street.

Moonstone dropped the use of her powers as soon as her heels hit the pavement. Sue blinked as her full faculties came back to her—along with self-doubts and recriminations. She couldn't believe that she had let the doctor do this to her again. Yet neither could Sue deny the excitement. Her bare nipples were hard in the open air, and her pussy was so wet she could feel it drip down her thighs. She moved with the ease of long practice, keeping close to Karla, not wanting to bump into anyone in the crowd.

Dr. Stone, for her part, took advantage of her unseen audience to tease Sue mercilessly. Whenever she had an opportunity, she would flip up her little black skirt—to show Sue Storm bare buttocks, no underwear at all.

Sue wondered at the sheer confidence to dress like that. To flaunt her body. So free, so unencumbered. Karla's cheeks were flushed with excitement, nipples nearly popping out of her corset. People on the sidewalk looked at her, but she didn't seem to care what they said or thought. The Invisible Woman's heart thundered in her chest when she realized that Dr. Stone was doing this for her—showing off for her—instead of embarrassing Sue Storm, she was drawing all the attention, demonstrating her own confidence, her own dominance.

They left the sidewalk and into Central Park. Then they left the paved paths for the unpaved trails. Into the trees, where the sunlight filtered through the leaves. Sue had heard there were streams here, animals, even a cave. A little slice of nature in the middle of the big city. The wind blew at her back, and she hung back a step as Dr. Stone walked ahead, trailing the invisible leash loosely behind her.

Then something dropped from the trees.

It looked, for a moment, like an ape. Then it stood up, as tall as a man. Thin, lanky, dressed in a tattered costume that didn't hide the bulge of his erection. Sue Storm recognized him. The Mandrill. Immediately, she placed an invisible bubble around her head. She had been upwind, not susceptible to the mutant's pheromones...but Dr. Stone shuddered, suddenly sweating.

"What do we have here?" Mandrill said, and he licked his fangs. "A blonde whore, all alone? Get on your knees and clean my cock with your mouth, slut."

To Sue Storm's horror, her mistress fell to her knees. The mutant man-ape pulled down his loose pants, and a brown cock popped out, the largest prick Sue had seen on anything human, a line of fine fur running down the back of the shaft like a crest, ending in a purple head that dripped a clear, viscous fluid.

Dr. Stone brought her hands up towards the cock...which tugged at the leash. Sue snapped out of her moment of frozen horror. She raised an invisible hand and formulated a complex thought...
