Ketchup Effect

"Wanna watch a movie on Netflix with me?"
Gabrielle looked up from her phone . "Sure! It´s my turn to chose the movie this time", she said with her innocent smile.
Adam groaned on the inside because Gabby always chose deep films with a lot of emotions. On the other hand she usually was up to sex afterwards.

They were one quarter into the movie and Adam was already losing it. It was time to use his secret weapon.
A week ago he had found an intriquely carved locked box at a garage sale and he bought it, hoping it contained something valueable. What he found was something more though. 
It was priceless.

It was an magical artifact. Adam couldn´t decipher all of the parchment that came with it but he got a broad picture.
With it he could  affect the thoughts of someone else and make them think like him.
Adam desperately wanted the movie to end but didn´t want to miss out on the sex so it was time to put the artifact to use.

He snuck it up behind Gabby´s head and activated it. Adam could feel the warmth of the artifact, a gem, heat up in his hand. 
The first ten seconds nothing happened but then Adam noticed that Gabby seemed to becoming disinterested in the movie. It was working! Adam continued with his channeling.
"What did I ever see in a movie like this!", Gabby suddenly spat out. "This is fucking crap! Screw this. I want to see something else". Now Adam figured he could make her stop watch chick flicks altogether if he just continued.

 

 "Whoa. I´ve never realized my boobs looked so big from this perspective", Gabby said, completely ignoring anything about movies by now.

Adam just sat and watched with a horny glee when his girlfriend began to undress and touch herself.

Now, magic can be capricious if you don´t know what you are doing. Something Adam soon will experience.
Ever heard of the Ketchup Effect? It can be applied to magic too.
First nothing, then a little, then everything at once.

The gem was still hot in Adam´s hand when he saw his girlfriends eyes move up in her head and slumped down in the sofa.
"Uh oh", Adam thought. Maybe he overdid it.

 

 He sighed a breath of relief though when he saw his girlfriend come about after just a couple of seconds of unconcioussness.
First she looked at herself and got a horrified look on her face, then she stared at Adam. "Did....did we just switch bodies?", she asked.

Adam didn´t understand what she meant. "...No?", still unsure on what was happening.
"It´s me! Adam!", she pleaded.
"No, I´m Adam", Adam said.
"I used a magical gem to switch us by mistake", we must find it!", panic was rising in her voice.
Adam put one and one together. She said she was Adam, and Adam was still Adam. That would mean that both was Adam. "Shit..."
"Dude. I think I know what happened....", he began.

 One explanation later and both Adam´s was on the clear what had happened. 
"Now what?", Adam-in-Gabby asked.
"We know that...you...", Adam gestured at his girlfriends body, "...have some residual Gabrielle in you so you can act like her to an extent. With our memories we can probably fake it for a while. Just to be on the safe side it´s better you move Gabby´s stuff in here was well. And avoiding contact with other people as much as we can until we have sorted out this mess", the original Adam suggested.

Adam-in-Gabrielle sighed. "Shit. I need something to relax my nerves", and went over to grab a drink.
"Bring the bottle", Adam said.

The pair drank the contents of the bottle to the last drop and it made both of them a bit tipsy.
A bit curious even.
What did it feel like for a girl?

Well, that question was answered in the bed.
