Kegels

After Sue Storm had tucked the children into bed.

After she kissed her husband Reed goodnight as he sat up in his lab.

After she changed into a pair of panties and a blue Fantastic Four t-shirt big enough to be used as a nightie.

It was time for Sue Storm's stress-relieving exercises.

"Hmm," Sue moaned as the egg-shaped invisible **** field slid inside of her body.

She closed her eyes as she tensed her pelvic muscles. Squeezed and held them. Felt that delicious tension. Dr. Stone had said that this was a way to relieve stress—and that it made the sex better.

Sue Storm counted to ten and relaxed. Not just her pelvic floor, but her entire body. Dr. Stone had told her that was important too. Not just to contract, but to relax. Not just to tighten up, but to loosen up. Sue counted to ten and then tensed again.

Kegels had been something Sue Storm had tried after each of her pregnancies. She was told it would help tighten her vagina after birth, though her fitness instructors had all warned about doing too much. It wasn't good to get too tight, to overstress the muscles of her pelvic floor. Bad things could happen. So Sue had left it off, for years.

Until now. Until Dr. Stone had recommended them to her as a way to relieve her stress, to get back in touch with that part of her femininity she had repressed and forgotten.

In her mind's eyes, she pictured Dr. Stone. No...Karla. So smart, so composed. Karla with her tight sweaters, who liked to show off that wonderful cleavage. Sue could almost hear her voice in her head. She could play it over and over.

The darkness settled on Sue Storm like a lover. Beneath the sheets the air was hot. Sue quivered as she held the tension for a long minute. Her nipples hard as her pussy muscles squeezed down on the invisible egg. Then, at last, she relaxed. Panted in the night as she saw Dr. Stone smile at her.

When her fingers slipped down beneath her panties, Sue Storm found herself warm and ready. As the invisible egg shifted in shape to something longer and more slender, as it began to move, the Invisible Woman rubbed her clit and thought about Karla. Until with a gasp all the tension left her body in shivery moment beneath the sheets.

Just a few minutes before bed. A little more each night. So that when Sue Storm finally closed her eyes to sleep, she sank deep into dreams sensual and surreal...in which Karla played a prominent role.
