Moonstone Spanks Sue Until Her Ass Is Red

The hand came down less like the wrath of an angry schoolmarm, and more like the caress of a giantess that doesn't know her own strength. Blood rushed to Sue Storm's face, her buttocks rippled at the blow, the **** of it moved through her body and she nearly spat out Dr. Stone's panties. The heroine had to bite down on the fabric, her saliva drenching the undies, to hold them in her mouth.

"One," Dr. Stone said, unable to keep the excitement and anticipation from her face. Sue Storm could not see the red imprint the heavy book had left on her backside, or the psychiatrist raising her instrument back for another blow.

It came down, almost exactly where the first landed. Pain lanced through the Invisible Woman's body. Her blue eyes watered. She did not wonder now at the horror in which corporal punishment was held. Sue had never spanked her own children, thinking it a barbaric remnant of an older style of parenting—besides which, Prof. Xavier had told her it really wasn't a good idea to spank mutants with potentially reality-altering powers, and he had dealt with enough of those that Sue had taken his word for it.

The blows came down, one after another. Not regularly. There was a pause between each one. A random gap that made Sue uneasy, unable to predict when the blow would fall. She had to fight an urge to project an invisible shield around her buttocks, but Dr. Stone would feel that—

—and what was more, Sue found she didn't want to.

The spanking was intense. The sharp pain of each impact seemed to race up her spine. Yet there was also something...exciting about it. An exhilaration like combat, but more intimate. She could feel blood rush to her ass, the pert posterior swelling slightly as it moved to the wounded backside to help it heal. Sue could feel the wetness in her exposed pussy, but could not see the cherry red color that her buttocks were turning after repeated blows.

Karla could. For someone of her superhuman strength and endurance, this "punishment" was nothing, not even a workout in terms of raw exertion. Yet Sue Storm heard the psychiatrist's breath quicken. Could almost feel the excitement that Karla radiated.

Until, at last, Karla let the book fall to the floor, and paused to admire her handiwork.

"Does it hurt?" Karla said, and gripped one red and swollen cheek. "Oh, sitting down will be a pain for you. Now—now is a good time to discuss aftercare."
