Sue Storm Succeeds - So Dr. Stone Increases The Difficulty

The weight did not fall.

That was what Karla noticed, even as Sue Storm's body spasmed and shook. The trigger words had worked. The Invisible Woman had spontaneously climaxed. Yet she had sunk, mentally, into some state of concentration that allowed her to maintain her power without interruption.

That would not do. Karla knew she needed to break Sue.

"Invisible slut," Moonstone whispered in Sue's ear. "That's what they think you are. The weak cunt of the Fantastic Four. Do you really think Iron Man and Captain America respect you? As far as they're concerned, you're just another pair of pretty tits."

The psychiatrist slapped the Invisible Woman's breasts, hard. The weight on its invisible column did not move.

"And the villains. To Doctor Doom and the Mole Man, you're a bimbo. Reed Richard's cumdump," Karla grabbed the Invisible Woman's pussy and forced a finger into the tight twat. It was wet; her finger slid in easily, and Karla glowered.

Time to change tactics.

"Maybe you like that?" Karla said soothingly. She didn't take her finger out of Sue's pussy, but began to wiggle it around. "You get off on being seen as a sex object? Maybe you fantasize about what it would be like if they ravished you? I can see you fingering yourself at night, thinking about Galactus impaling you on his god-like shaft like some sort of living sex toy."

Sue Storm's blue eyes were open, staring straight ahead, pupils dilated. Sweat beaded her skin flushed with arousal. Yet there was no crash of the weight falling to the floor.

"Cum for me, super slut," Karla said, her eyes glowing, and she heard the swift intake of breath, felt the crush of those vaginal muscles on her finger. "Cum for me and fail, cum for me and let that weight drop, cum for me like the worthless cunt you are..."

At each use of the trigger word, Sue Storm spasmed. Her pussy juices ran over the villains hand, Moonstone's fingers plunging in and out of the sodden slit. Yet Sue Storm was stubborn, determined, disciplined. She knelt there and it was like an ice cube sitting unmelted in the heart of a fire. Karla shifted, four fingers trying to squeeze their way inside of Sue Storm's tight cunt.

Sue could hear Karla. Her body was responding. Yet her mind...Karla knew she needed to break down Sue Storm's mind. The villain reached for a bottle of lube and dribbled it down the crack of Sue's ass.

"You think you're doing so well, don't you? The prim, proper heroine, overcoming your innate lust. But what happens if a villain makes you cum with your ass?" Karla whispered.

For the first time, as Karla pressed a finger against the heroine's bumhole, Sue Storm's shoulders began to sag. Her pucker tightened as Karla applied more pressure, but the villain's digit was lubed and her own superhuman strength was greater than that of the muscular sphincter.
