Meanwhile, three streets over, in the wealthier part of town, Sarah was taking a shower.
Right after Jen's mom had made her wish, Sarah had started to change. As she was washing herself, her size-D breasts began to shrink until they became size-A breasts. She didn't notice. Her long hair became shorter. She didn't notice. Her body became more muscular. And, again, she didn't notice.
After she was done taking a shower, she began to get dressed and get ready for school. All the make-up, jewelry, and so forth, were gone. She wouldn't need all that stuff. She was a tomboy now. Well, to anyone else's point of view. To Sarah, she had always been this way.
She was no longer a cheerleader. That was too girly for her. She liked doing more boyish things.
All the other girls that were cheerleaders, however, lived in a different neighborhood, so they hadn't been affected by the wish. And, they didn't know that Sarah was a tomboy now.
