A woman

Will suddenly felt as if he wasn't allowed to wear his clothes. He stripped as quickly as he could, only regaining control of his body once he was naked. Of course he realized he now had the body of a woman, "What the fuck?" Sally was just staring at him, practically drooling. He shrugged, "I guess you never specified that the other version had to be male. Well, time to switch back." He snapped his fingers three times again and returned to his male form.

Sally had been totally silent when he'd been a woman, but now she came back to life and shrieked, "Oh my God, you're naked!"

Will quickly turned around, "Oh sorry," He pulled his clothes on as fast as he could and then turned around again, "Had to once I had that female body."

Sally looked confused, "Oh right. You were a woman, and you took off your shirt...and then you were a man again. I don't remember you snapping."

It was Will's turn to be confused, "Wait, you don't remember anything after I took off my shirt?"

Sally shook her head, "Nope. You took off your shirt, I saw the most amazing breasts ever, then you were suddenly a man again and I had to look away."

Hmm...Will had an idea of what his new superpower might be. It could be useful, but it certainly lined up with how their other successful wishes had been going. Could it be...? He'd have to test it out. "ok, I have an idea. Turn around please." He said to Sally.

Once she was facing away he took off this clothes again and snapped three times. First he tested his voice, "Sally can you hear me?"

Sally nodded, "Yep. You're a woman again?"

"Ya, but don't turn around. You don't feel strange or unusual?" Will asked.

"Nope. I'm fine."

"Ok, now please close your eyes and turn around." Sally did so and she still seemed perfectly normal. Will grabbed a pillow off the couch and held it above his chest, "Ok now open your eyes."

Sally did and smiled, "Wow. You make a hot woman."

"Ya ya, you still are with me though?" She nodded. Will dropped the pillow and immediately Sally's jaw went slack, "Sally? Sally?" Sally didn't reply. That pretty much confirmed his theory. Some kind of breast induced hypnosis. Great. Maybe he could use it to implant thoughts or commands? "Sally, nod if you hear me." Sally nodded, "Sally say cheeseburger."

"Cheeseburger." She said in a monotone voice.

"Sally squawk like a chicken." She immediately started squaking, "Stop. Hop on one foot." Sally immediately started to hop, "Ok you still stop hopping in 30 seconds." He immediately snapped his fingers three times.

Sally blinked, but kept hopping. She looked at him confused, "Will? What's going on? Why am I..." Her time expired and she stopped. "Ok, why was I just jumping? What happened after you dropped that pillow?"
