What Modifications Should He Make?

A Strength Booster

With a snap of his fingers, John watched as his beautiful delinquent girl (only now did he realise he never even knew her name) swelled up with impressive amounts of muscle.

First it was her arms, her deltoids billowing out like huge cushions of meat around her head. They strained and rippled beneath the sleeves of her T-shirt, tearing them clean off with one powerful flex. Then, her biceps swelled to yoga-ball sizes, with rope-like veins running like lines on a map over the mountains of muscle her upper arms had just gained. Her lower arms then began to swell too, and soon they had reached the size of rugby balls. The growth soon spreads down to her hands, which harden as if covered by thick leather. Her fingernails became black and sharp atop her meaty sausage fingers, and her knuckles were covered a layer of fine hair.

John felt himself grow giddy at the sight of her body, her huge arms and hands that could crush his skull in, sitting on her normal (but still athletic) lower body. She was **** to walk around like a bloated gorilla now, as her arms were longer than the entire rest of her body, and twice as strong as any bodybuilder's wet dream. He pressed his nose up against the glass, sighing as he watched this muscular thump around her bedroom, so gloriously large and powerful.

But this wasn't enough. He wanted more.
