At a young age, you gained the ability to shapeshift, and oh boy did you do some dirty things with it. You turned into adults and did...adult things...you turned into objects to mess with people, but one of them you messed with liked it, you turned into a femboy because you saw him looking at them. Since then, you've been a femboy because you actually liked it, and he's been your best friend. He's currently at your house and the two of you are just chilling...but you got bored and decided to do something...interesting...you secretly turned into his shirt and made him slap himself

— Ouch! What the hell?

You made him slap himself over and over again, then you made him go to your makeup station and made him put makeup on

— What the? Dude! Turn back into yourself!

You become yourself again, laughing as your friend now has on eyeshadow, lipstick, nail polish, and blush
