Mark stepped into the room with a triumphant smile on his face and said:"Bet you didn't expect that, huh? Now you'll be able to have a taste of the "other gender" for yourself, as you always call it." The girl who was more than a foot shorter than Mark stammered:"Who...who are you? And what have you done to me?" "Silly girl, pay attention, I just explained what I've done to you...the same that I've done to myself", Mark chuckled. "You see, I'm actually Mary but I changed myself into Mark and to let you have a taste of your own medicine I've changed you into...what shall we call you? Jessica seems good." Jessica was white with anger and shock. "Change me back right now!" Mark laid a gentle hand upon Jessica's shoulder:"not till you've learned to have some respect for your new form...and seeing as it's gonna take some time reeducating you, what shall we do first?"
