Kathy slipped out of her burgundy babydoll and joined Rob in the bed. She slowly caressed his smaller dick and balls and quickly rekindled his erection.
He fondled her huge breasts still amazed by her new height.
He went on top of her and wanted to penetrate her but she held him at bay. The more he tried to struggle, the more he realized how strong she had become.
"Only if you agree to become smaller and then give me the shoes to let me grow a bit more. Will you do this for me?" she asked Rob.
He mumbled something, visibly annoyed.
"Say it louder!"
"Fine I agree to shrink more but only for a short time. After, you will bring me back my original size."
"Of course, my love." she said releasing him from her grip.
His rock hard dick finally entered her wet pussy and he pounded into her. He tried to compensate his diminished size by his activity.
To him her vagina was huge and love was clearly different from what he was used to. For Kathy it was clearly worse.
She wondered if she could use the magical shoes to make him grow grow inside her. Maybe if she put some of her height in the shoes and they made love standing? But first, Rob would have to shrink even more.
He came inside her and they spent a moment in each other's arms.
Kathy was the first one to stand from the bed.
"Now it's time to keep your promise." she said, holding her pink slippers in her hands.
Rob stood slowly, still frowning.
"I'm sorry if I've been a bit pushy. I have been fantasizing about becoming taller for a long time but I never thought it could really happen."
Rob took the cute pink slippers and put them on.
They were several sizes too big for his shrunken feet but after a few seconds, they instantly became a perfect fit.
Kathy kissed his lips and said "Thank you for going along with it. I love you."
"I love you too."
"So you have to stand with your weight balanced on both feet and choose the style and height of the shoes."Kat explained.
Rob thought for a while, cleared his throat and said...
