I've been dreading my 18th birthday for years, don't get me I couldn't wait to be an adult it's just my family has a curse from a Witch several hundred years ago, where when we turn 18 our body changes into the opposite sex for a year and if we get cum inside us or cum inside a girl it becomes permanent.
So here I am 12am on my 18th birthday waiting for the changes to happen when suddenly;
crack
my back cracks shrinking down.
crack crack
my limbs follow shortly after.
"Ahhhh!" I groan from the pain of my body changing.
pff pff
I feel my body hair fall out and softly land on the floor making my now wrinkle and hairless skin soft and smooth.
slurp
I hear my skin and muscles tighten and shrink to fit my shrinking body. I was once 6'1" now I'm 5'5" but the changes weren't done there, I feel different as my testicles suck up inside turning into ovaries
pop
"No no no!" My penis follows inside shrinking down to a small clit.
I feel the hormone change as my nipples begin to build pressure behind them.
My chest inflates growing two C cup size boobs bouncing with every movement I make.
crack
I feel my hips widen and my body figure change to be more feminine and slowly the pain dies down giving me a chance to catch my breath. I stood up and walked to my mirror and check out my new body. I was a hot Goth chick complete with make-up of my face, I then noticed the box of clothes my parents gave me for the year.
The following morning I eagerly got changed and went over to my buddies place to show my hot but temporary body off to him Long story short we got carried away and tried sex but I made sure he uses a condom and for months we had the greatest sex without making my changes permanent till today. We were fucking when he was getting ready to cum when…
rip
And he yelled out moaning
squirt
As I felt his warm cum enter my womb cumlocking me inside this form."Dude what the heck, you heard the condom rip why'd you cum inside?"
