Chain reaction

This series was based on a series of captions from another caption blog but I can’t remember which one. If you know, put it in the comments.

Max (19) floated up out of his body, ecstatic that he’d finally got the spell to work. He swooped though the air, invisible, before sinking through the wall into the room of his sister, Emily (20). She was on her bed, flipping through her phone.
Max floated around, pulling faces with his invisible body, laughing at the fact that she had no idea he was there. He flew towards her, intending to pass right through her, but as soon as he flew into her body the world flipped and suddenly he had a physical body again.
He was lying in bed looking at a phone. But the fingers holding the screen were slender and delicate. he sat up and swore in his sister’s voice, then looked down at himself.
“Well, I’m in my sister’s body,” he laughed to himself. “Might as well enjoy it.”
He figured he could always go back. He stripped naked and straddled the chair, staring at himself in his mirror. His sister’s soft face looked back and he brought his hands up to her chest, feeling her bouncing breasts. The cool air of the room caressed his pussy and he felt himself growing wet as he ran Emily’s hands over her supple body.
Emily had been bounced from her body the instant Max had entered it. She didn’t know what was happening and tried to push herself back into her body but was blocked. She only realized who was inside when Max spoke to himself. And then he started touching her! That little pervert!
Emily was determined to get her revenge. She flew back to Max’s room and tried to take over his body. But she was again bounced away. Terror gripped her. She was body-less. And the world was starting to go grey. She could feel herself fading away, soon to be nothing. Unless she got into someone else’s body.
