Helen is possessed!

Adam instinctively backed away from Helen as her body jerked wildly. It was as if she had been hit by an invisible ****, her arms flailing irratically. As quickly as her body had started to move, it stopped and she stood there, head drooping to her chest.

"Helen, are you ok babe," Adam said, approaching his girlfriend cautiously.

"Yes, I'm fine," Helen replied calmly. Her head rose up so her eyes could meet Adam's. They looked normal and she had a gentle smile on her face.

"Are you sure?" Adam stared at Helen with a raised eyebrow. "You just spasmed all over the place. It was pretty weird."

"I'm sure, but I'm not Helen."

Adam frowned deeply at his girlfriend's last comment. "What do you mean you're not Helen?" he asked growing increasingly worried by her behaviour.

"It's me, Aga," Helen said, putting her hands on her hips. She looked at Adam expectantly, apparently waiting for his response to her statement.

"You're Aga?" Adam said. He looked deeply into his girlfriend's eyes, perhaps expecting to see some sort of glimmer that would indicate she was lying. Whatever he was looking for, Adam didn't find it. He did recall, however, the conversation he had only just had with Helen. "Please don't tell me this is something to do with that spellbook."

"She told you huh?" Helen, or perhaps Aga, said with a smirk. "I suppose she said I stole it from her?"

"That is what you said, yes," Adam said, not convinced that his girlfriend had been possessed by one of his close friends. Helen was someone that enjoyed acting, and Adam supposed this was some new way that she was practising entering into a role in an instant. He couldn't think why she'd pretend to be Aga though. Helen hated her.

"I didn't think you'd believe me," Helen said, wagging her finger at Adam. "I suppose you'll be wanting some proof I'm really Aga then?"

"That would certainly help," Adam agreed, though he didn't expect much. "Why don't you tell me something only Aga would know?"

"Easy," Helen chuckled. "There was that time you got an erection round mine, just from watching me put my socks on."

"Fuck off," Adam scoffed, going red. "Aga probably told you that on a night out or something. She loves embarrassing me."

"That is true," the supposed Aga agreed. "But remember Helen and I don't get along. We've barely spoken."

"Tell me something Aga wouldn't dare have shared with anyone then!"

"Ugh, you're really making me go there? Fine. You once walked in on me playing with myself and I let you watch me if you promised not to tell anyone."

Adam's jaw dropped and he pointed an accusing finger at his girlfriend's body. "Aga! That really is you!" Adam stood in wonder, certain that one of his best friends had somehow managed to possess his girlfriend. "So Helen was telling the truth, you really did argue over a spellbook in the shop?"

"Yep!" Aga said with a grin. "I couldn't let that dull girlfriend of yours steal such a wonderful artifact from me. She'd have used it to help her acting career or some other bollocks. Whereas I can use its power for something more fun!" Aga stepped in towards Adam and caressed his cheek with her hand.

"W-what do you mean?" Adam stuttered.

"You've told me how vanilla and boring she is in the bedroom. I'll let you do whatever you want with her body," Aga purred. Her eyes smouldered, suggesting all sorts of elicit pleasures. "Or anyone else's for that matter."
