Sue Storm Is New To Fucking Women, Moonstone Doesn't Cum

The Invisible Woman was pounding Dr. Stone's snatch, the vibrator held in an invisible strap-on. The solid, massless force field did not translate the buzzing and impact, but a portion of the force field pressed against Sue's clit and extended into her pussy. With each thrust, Sue Storm felt her own pussy stimulated.

"You like that, slut?" Sue Storm grunted as he slammed the vibrator deep. "You like it when Mistress Susan fucks you!?"

Dr. Stone sighed. She was bound in place by Sue's force fields. Her cunny felt like hamburger. The Invisible Woman had been slam-fucking her for almost twenty minutes, the heroine's toned and fit body dripping with sweat at the jackhammer workout. Any woman who lacked Moonstone's superhuman durability would be bleeding now.

Karla...felt bored.

It took more than just penetration to get her off. She needed more stimulation. Clit rubs, nipple twists, maybe some deep kissing. Even spanking would be preferable to the endless sawing of the vibrator in and out of her juicy cunt. It wasn't that it didn't feel good, it just wasn't enough to get her off. Which reminded Karla of the time she had let herself be taken by Norman Osborne. He had the same basic philosophy. Rapacious, self-centered, uninterested in her pleasure...

Sue Storm slowed to a stop. She frowned, and the invisible bonds vanished. Moonstone could move again.

"You're not cumming," Sue Storm said. "Why? What am I doing wrong?"

...but nowhere near as perceptive as the Invisible Woman.

"With respect, Mistress," Karla said, playing coy as she stretched her limbs. "But you're fucking me like a man. Just pounding away. No woman has ever cum like that. You're a woman. You've experienced your husband crawling on top of you and pronging away. To what effect?"

Sue Storm considered this. She held up the vibrating toy. Then ran her blue eyes up and down the naked form of Dr. Karla Stone as she stretched. Slowly, the Invisible Woman nodded.

"You're right. I've been going about this all wrong."

There was something in her voice that caught Moonstone's attention. An edge that hadn't been there before. She knew that Sue Storm was new to this whole lesbian domination play, and that only Moonstone's own mental manipulations over weeks had driven the Invisible Woman to this point. Sue Storm's mind was unsettled...and Karla didn't know what she might do.
