"WHAT ARE YOU DOING?" Marie screams at you. Her voice start to drop a few octave. You notice an adam apple start to grow on her throat.
You just stay silent. After changing your girlfriend into a crossdresser boy, you knew that deep inside you like male. So, you secretly hoping your girlfriend change into Marcus, your best friend.
You can see Marie body clearly since she hasn't put any clothes after the last transformation. Unlike the last transformation, now it seems her inner organ start to change first. Her bone grow longer and bigger, adding her height from 5 feet to 6 feet. Her ovaries change into testicles. Her vagina gradually forming a penis. It's small at first but quickly lengthen to 7 inches, followed by big balls hanging quite nicely.
You see Marie's big penis, and thinking it's more appropriate to address her as a he. Although Marie's hourglass figure hasn't changed yet.
"I'M A MAN AGAIN?!?? WHAT ARE YOU? ARE YOU GAY?" Marie has deep baritone voice now. His adam apple clearly protruding from his throat.
Seeing Marie's hanging penis aroused you. You start unzipping your pants and stuck your penis inside Marie's mouth. Although, he was shocked at first, Marie seems to enjoy your cock. You feel his tongue licking your penis. You grab his long blonde hair and feel it is slipping your hand. Marie's long blonde hair start to retract inside his skull leaving a bald head. When you cum inside Marie's mouth, his face rapidly transform into your BFF face, Marcus. His beautiful Swedish face is changing into an African descent male face. His nose and mouth grows. His eyes become black.
Seeing this, you pull your cock and shove it to Marie's round and sexy ass. Your body and your boyfriend body move in a rythm. You notice his back is changing from slender female back into hard with muscle. His biceps grow significantly. You try to cusp your boyfriend breast, but at each thrust, it deflate into hard pectoral muscle. Marie's belly becomes hard and six pack appears on his belly.
Marie is like a clone of Marcus now, only his skin tone still light tan. You shoot antoher load of sperm inside Marie's ass just at the same time as Marie's. It seems to trigger the final change. Marie's skin start to darken, completing his African heritance.
You see your boyfriend face smiling at you. "Wow I don't know that fucked by a boy is this good", Marie said. "Wait Marie, you aren't mad at me anymore?", you confusedly asked. "Look babe, I know I agree to have sex with you in one condition that I'll pretend to be a woman named Marie, but I like you and I want to accept me as Marcus. Not as an imaginary Swedish girlfriend of yours named Marie."
