Dr. Stone Is A Very Hands-On Teacher

Sue Storm wasn't sure what she expected when she knocked on the door. There were butterflies in her stomach. What would Dr. Stone wear? What would she do? Would there be charts, or videos, maybe a medical model—

The door opened. Dr. Karla Stone stood there in a pristine white lab coat, hair up in a severe bun. She was wearing latex gloves, and smiled at Sue as she ushered the heroine into the room.

The layout had been changed a little. The chairs had been pushed into the corners; a folding screen had been set up on the left-hand side of the room, and in the clear space in the middle had been set up something like a gynaecology chair. A full-length mirror stood off to one side by the desk.

"Behind the curtain," Dr. Stone pointed. "Disrobe, please."

"Why?" Sue asked.

"Because I'm going to teach you how to masturbate," Dr. Stone said, with a carefully neutral smile, her glasses doing that trick where they caught the light and seemed to glow. "It's no good for you to just watch me do it. You need to feel it, with your own hands, your own body."

Sue turned. Her heart hammered against her breastbone. There was a chair behind the screen, and a small rack for her shoes. With a swallow, Sue disrobed. She shook a little as she did so. This seemed insane. Yet it was exciting. And...and maybe it was Sue's mind making up rationalizations, but it made sense to her in the moment as she undid her bra and peeled off her panties and set them carefully on the chair on top of her folded clothes.

She came out, feeling oddly ****, visible. Dr. Stone had lined up items on a towel on the edge of her desk. A bottle of lube. A selection of toys, some recognizable, others Sue had never seen before. With a nervous smile, Sue sat on the chair. Momentarily surprised to find that the back was less solid than it looked, but more like a kind of web of reinforced fabric. Her hands instinctively covered her crotch.

Carefully, Dr. Stone bent down to take Sue's feet and set them in the chair's uplifted stirrups. She smiled at Sue, but instead of trying to take her hands away, she set up a mirror so that Sue could see herself. The doctor then turned and moved behind the chair.

What happened next was surprising, even to Sue. The Invisible Woman hadn't bothered to look at the back of the chair, hadn't seen that it was essentially hollow, with a kind of seat and slots for legs. The doctor slid into place behind Sue—and then her hands came around, and slid down by touch over Sue's forearms, to grasp her wrists. With surprising strength, Dr. Stone peeled Sue's hands away, so that the naked heroine could stare into the mirror and see herself completely exposed.

Dr. Stone smiled. A strange aura grew around her head as she exerted her power a bit more, to keep Sue pliable as she guided the heroines hands back to her own pussy. Her voice came up from behind Sue, and the Invisible Woman stared at her own body as Dr. Stone slowly took her through a hand's-on lesson of her own anatomy. The parts and functions of her pussy. The words and terminology.

"This is your pussy, slit, gash, cunny, cunt," Dr. Stone intoned.

"This is my pussy, slit, gash, cunny, cunt," Sue echoed, eyes fixed as her own fingers, guided by Dr. Stone, spread out her wet, glistening sex.

"When your gash is wet, you need to rub it," Dr. Stone continued, and she guided Sue to rub her clit with slow circles, using the pads of her fingers.

"When my gash is wet, I need to rub it," Sue repeated, utterly enraptured.

Faster and faster they rubbed. The words repeated over and over, Sue's eyes were glued to the sight of her own slutty slit as she frigged her gash, faster and faster, her nipples hard and sensitive. Her breath came in quick gasps as she felt the anticipation rise inside of her, thighs a-quiver, toes curling and...

The first climax took less than ten minutes. Sue's whole body seized, the stirrups prevented her from bringing her legs together, and stars danced in front of her eyes.

Even Dr. Stone paused, the light dimmed as the doctor breathed heavily, blood pouring down from her nostrils.

"Now," Dr. Stone said as she withdrew her arms. "Try one on your own."
