Day 4.

Jenny's head was throbbing. She blearily opened her eyes and stared at an unfamiliar ceiling. What happened last night? She rolled over and her stomach lurched, threatening to disgorge its contents all over the floor. She groaned and laid back down.

Where was she? She thought about it. Jay! That son of a bitch! She scowled as the previous day's events came flooding back to her. Jay had fucked around on her! And now...

She gasped and rushed into the bathroom. Staring back at her from the mirror was a woman who looked terrible. Bloodshot, heavy-lidded eyes set in a pallid face. A mouth agape with horror as she looked over herself. Green eyes, a button nose, shoulder-length curly black hair. Her cheekbones were a little higher and her face a little smaller. Speaking of smaller, the woman in the mirror couldn't be taller than 5'2, a striking contrast to her 5'9 frame.

She heard someone in the other room calling her name. Claire! She and Claire had- shit, shit shit! She needed to deal with this now. She ran to the bedroom and hastily threw on a pair of panties and a bra. She noticed that her breasts were now a bit small for the C-cup bra. As she was putting on her pants, Claire walked in with two cups of coffee.

"Morning, sleepyh- what the fuck!?" Claire jumped backwards, spilling coffee on the floor as she did. "Who the fuck are you?" She squinted. "Jenny? What happened to you?"

Jenny looked at her pleadingly. "I can explain! Please, just calm down. I'll explain." The other woman sat speechlessly on the bed as Jenny began to recount the last few days. Claire listened in silence, then spoke when Jenny was done.

"So Jay goes out and cheats on you, and now you're both- what, turning into someone else? That makes no sense, Jenny. Do you really expect me to believe that?"

Jenny nodded. "I know. I hardly believe it myself. But look at me! I'm actually shorter. You can't fake that with contacts or hair dye. I'm really changing, Claire. I'm scared." As she said it, she realized that she wasn't scared. At least, not as scared as she had been the previous day.

"Jenny, this is fucking crazy. You can't just... change! We must be hallucinating or something. This isn't really happening."

Jenny thought about it. "You want to see crazy? We should check in on Jay. Things must be getting really weird for him."

Claire stared in disbelief. "You wanna see Jay? That piece of shit who cheated on you? Why the fuck would you want to see him? Seriously, what's going on with you?"

Jenny frowned. Claire raised a good point. Why would she want to see Jay? "I don't know why, but I'm not very mad at him anymore. I remember our fight, and I still think he's a total shithead for what he did. But it feels like I read about it in a book or something. It doesn't seem real to me."

Claire considered this. It sounds like they needed Jay's help to get to the bottom of this. As much as she hated the guy, Jenny was right - it was time to talk to him. "Ok, well at least let me call him. He doesn't deserve to talk to you after what he did." She pulled out her phone and dialed him as Jenny shrugged.

After four rings, she heard the beep of him accepting the call. There was a long pause. Finally she spoke. "Jay?"

A distinctly feminine voice answered, completely unlike Jay's. "I don't know."
