Dr. Stone Stretches Sue Storm's Pussy

Moonstone placed her hand on the naked heroines' flat, toned stomach. Not the washboard abs of a bodybuilder, but the well-defined muscles clear beneath the soft skin. The villain felt the heat of her body. The way it flexed beneath her touch. She let the soft tips of her fingers trace down to the crotch, where the invisible cock pistoned in and out of that heroic cunny.

Dr. Stone's nostrils flared.

"Hold it," she said. "Push that invisible dick inside as deep as it can go, and hold it."

The implants buzzed in Moonstone's head maddeningly, but the elation in her body made it feel like a song. Beneath her, she saw Sue Storm's pussy stop moving. Splayed open wide, those pale thighs quivering. Moonstone let the pad of her middle finger touch the swollen bud of Sue's clit. The beautiful blonde bitch moaned like a whore. Moonstone rubbed the clit in a soft circle, half-watching her body strain against the ropes.

Then the villain curled her finger. Pushed the tip down until it met the smooth invisible cylinder embedded in Sue Storm's cunt. Right to the line where pink pussy-flesh met the invisible dildo. To apply just a bit of pressure...

Sue gasped. Her body arched. Yet Moonstone's strength, even in her finger, was implacable. An impossible **** pressed against Sue Storm's filled pussy—and the pussy began to give way. Stretched. Blood oozed down Dr. Stone's nostrils as the fingertip **** its way into Sue's overstretched cunny, the integument stretched taut as she pushed it further. The tight tunnel squeezed her finger as Moonstone pushed deeper. She didn't stop until her whole finger was in there, right up to the knuckle.

Then she curled her finger. Found that special spot which made Sue Storm's eyes roll up in her head and mouth gape open, to release a sound from deep in her lungs. A tiny gravitimetric pulse...

Sue Storm didn't scream in pleasure. The sound she made wasn't human. The rope didn't snap, despite the strain of her muscles, but pretty patterns marked her skin. Moonstone wondered how the Invisible Woman would explain those marks to her husband and family.
