The stone flashed, causing Jon to close his eyes. When he opened them, he was greeted with an entirely new look for his bedroom. It was very clear that this room did not belong to a boy, but rather a girl.
Looking into his bedroom mirror, which had become a vanity, he saw that he was a female version of himself, looking more like a teenage version of his mom than an older version of his sister Zoe. The girl he saw was hot. Dirty blond hair, maybe D-cup breasts, thin but also curvy in all the right places. And her outfit was hot too. In fact, the way she was dressed, it was clear that she was part of the popular crowd.
At that moment, the doorbell rang. Considering that he had just seen Biff outside moments earlier, and also considering what he had just wished, it was probably Biff ringing the doorbell. But how could Jon even go see him? He had just become a girl! He wasn't used to this. And he didn't want to get used to it.
The doorbell rang again. Biff was impatient.
Obviously, the stone made it so that Jon and Biff were dating. But Biff was straight. So it turned Jon into a girl. The type of girl Biff liked. What was Jon going to do?
