When Valerie took her thumb off the cube, the image showing was her, only this Valerie had muscles larger than Jenny had ever seen. Valerie closed her hand around the cube and smiled with anticipation.
Suddenly the growth began, every muscle in Valerie's body contracted and then swelled as if being filled with air, only it wasn't air, it was raw power. Valerie laughed as she began to flex wildly, marveling at her own incredible body. With each flex she grew taller and more muscular. Her already slim clothing became stretched to the max, and then with a mighty flex, her shirt and shorts were torn asunder, revealing all of her beautiful bronzed body. As the growth finally subsided, Valerie loomed over a Jenny, sporting muscles easily twice as large.
Valerie opened her eyes and ran a hand over her body.
"I'm a goddess" She whispered. 'I'm a fuckign GODDESS!"
She wasn't far from the mark. Valerie now stood at 7ft tall. Her biceps swelled to the size of bowling balls. Her back was a wall of muscle over three feet across. Rippling abs ran down to her bulging thighs. Her calves bunched into rock hard diamonds. She flexed her muscles in succession, feeling power surge through her.
"Look at me now you pathetic little girl!" Valerie sneered. " I'm the most powerful being on earth! I can do anything! And I owe it all to this little cube of yours!"
Jenny could only gaze with awe and fear at the Amazon goddess before her. Valerie continued to talk.
"This feels so fucking incredible.At last I have the power I've always dreamed of. Fuck being a skinny little weakling. With this body the world is mine to control!"

Jenny continued to stare in shock at Valerie...
