Age-shifters twins

"Come on, Granny, please, take us to the beach!"

"It's hot, we want to bathe, let's go granny!"

Nathan and Elsa were pressing Catherine, their 70 YO grandmother, eager to enjoy the sea on this beautiful summer day. Their enthusiasm was, however, largely diminished by the fatigue of the old woman, who, especially today, was experiencing joint pain.

"Sorry children! Your grandma is not feeling well today ... Old age ..."

The two teenagers, at first disappointed, then cast an amused glance.

"Maybe we can fix it, Granny!"

The twins shake their hands and activate their Age-shifting powers. In an instant the pangs of their grandmother vanished. She felt even more energetic than she had been for 20 years.

"What have you done to me ?!" She wondered, realizing that her little children had just accomplished a feat.

"Nathan and I got power! We can make younger or older who we want as long as we hold hands, but it only lasts 12h"

Catherine looked at herself in a mirror and found that her hair had recovered a little of their brilliance. She estimated her current age at 50.

"It's ... miraculous"

His two children smiled.

"Can we go now, Granny?"

"Wait !"

"What again ?"

"Your power ... how much can they rejuvenate me ?" Catherine asked timidly

1h later, while Elsa and Nathan rushed into the water, their grandmother went to lounging on the beach, enjoying her 25-year-old body her grandchildren gave her back, wearing a bikini found in the old business of her youngest daughter.
