After ten minutes of waiting, he thought that maybe he should try his previous wish out.
He wished: "I wish that my sister zoes breasts will grow two cup sizes"
After he was done he thought that he should check his wish out and went downstairs.
He saw his sister zoe sitting on the couch like always at this hour.
But something was different, her bust.
Her bust was pretty big, maybe even bigger then Karyns breasts.
And he got a boner as he watched them jiggel with every movement she made and how her nippels poked out in front of her tank-top .
Remembering that this was intended to be a test, and not some perverted fantasy of his he wished:
"I wish that my sister Zoes breasts would shrink back to their previous size"
And shortly after he said that he turned away and after he could turn again he saw his sister sitting in her previous spot, but this time with her smaller bust.
A small grin came across his face as he thought of all the possibilitys he could do with an unlimited stone.
He rushed fast back to his room and locked, he got some serious wishing to do.
