Why can I not jump back? by Rhodry

Billy was one those kids, he was nature bully, he learned early in life he was smarter than the average person, but he isn't consider highly to intelligent, which gave him problems so, hide his problems, he hated the fact others could be more smarter, which secretly gave him problems. Anthony in other hand was more smarter, than rest of the school, never-mind the school district. Never mind the state?

Billy was aware the Anthony, was building a memory device, that could copy, duplicate other persons memory in sense, help other people improve there lives.
But Billy knew it was a great idea, for him. And only him.
But the machine was still in beta testing, it was still a work in progress.
But Billy didn't care. He slowly sneaked around, to take or copy. Even take it.
At the moment he put it on, he activate it. Something happen to the device, a moment he felt that, he was himself and another person. The other person, was Anthony pretty mature mother. But things did as he expected. He thought he get the dirt on Anthony.
He never expected to Anthony mother. So he decided to have some fun before. He returned to his body.
But the device didn't work as it should, he tried to believe himself again. When Anthony checked his device, he was Billy as her mother. Billy couldn't understand, why he couldn't return back to himself.
Anthony, said that the device was no more, ready to experiment animals than people. At the moment, Billy was no more he was Anthony's mother total and completely.
SO, YOU have to find away to get my body.
I don't have to do anything, he said. Well if you like my invention, here is one of them.
A flash of light struck Billy.
And He blacked out.
Moment later, Anthony's mother woke up. Dazed and confused.
I, I feel strange, I, I have those memory of someone, else.
I'm sorry, but the device, broke down, mother you have memories of a former student, sorry mother.
She left to her bedroom. And slowly started to undress herself. She couldn't that feeling that she was someone else.
