Muscle Transfer

Jake Samson is the biggest and strongest guy around, and everybody knows it. Nearly seven feet tall and incredibly muscular, he's an imposing presence. Women are delighted with his size, and men intimidated by it. Jake's just used to it. He's always been the biggest and strongest guy around.

And then one day, he isn't. In fact, his situation becomes completely reversed. Suddenly he's the smallest and weakest guy around, barely coming up to most women's chins. He's weaker than them! His place and his power are taken from him. And the cause? An innocent wish made by Delilah Jameson, one of the women previously delighted with his size. As Jakes becomes tiny and weak, Delilah acquires everything he's lost – she becomes a towering, muscular amazon, seven feet tall, with arms and legs like tree trunks, and strength greater than any man around.

This is a transformation sequence, not a full story. There isn't much of a plot, it's an attribute theft sequence – male shrinking and female growing.
