You start to think, why you don't change your entire muscles?, so you wave you wand and said,
"I wish i had a big bodybuilder body, and a big cock and ball"
So, the wand do it's job, your body started to packed with muscles,and your cock and balls became bigger, but the one which shocked you is, a beard suddenly appeared, already shaved style, "Wow, it's- wait, my voice changed, I'M AN ADULT NOW!", you very suprised and happy, until it's stopped
You look at yourself, your height probably at 8 foot now, your muscles are heavily huge, and you looked down, and you suprised your cock at 4 feet long and your ball at size of softball, you flex your muscles every bit of it, and enjoyed it, even you have erection and fill your room with white liquids, "oh yeah, this gonna be good.."
The next day, you change your clothes with somewhat, fitted your body, and your noticed the wand is gone, so you change your identity, take job as bodybuilder, and get married, you enjoyed every life you got
End? it's up to you
