You feel yourself transform

The hyper hung futa smirks at you.
"Boys are fun to break, but I prefer someone a little more, feminine."

Your cock shrinks to nothing and you feel something open up between your legs, you now have a brand new pussy and female reproductive system, your voice gets higher, small petit boobs grow from your chest and your hair grows longer. By the end of the transformation she looks excited to break in your new body.
