(Um, what was that light just now sis?)
(That had to be the magic, although unfortunately, it didnt work exactly as planned.)
(Why, what happened?)
(Well, it isn't the worst thing, but it isn't good. Basically, you and I are now bodyparts on my body, but I am no longer in control.)
(Wait, I know I am still your boobs, but what are you?)
(My new, softball sized, testicles.)
At that you couldn't keep yourself from laughing, however all of a sudden milk began erupting out of your nipples. It was then you heard the former Scarlett's body moan out "Hey, keep it inside you for a bit longer will you Boobies! I don't want to ruin another top."
Now it was Scarlett's turn to laugh. (Hahahaha, you name is now Boobies!! OMG this is like, so amazing. Hey Boobies, welcome, to being a girl.)
It then dawned on you, your mental voice now was almost identical to Scarlett's. You needed some answers, and the first thing you needed to know was who is now in charge. (So, if the real Scarlett is now a pair of balls, who is controlling the body?) You ask, probing your host's mind to hopefully get some answers.
