Try for a little payback

You kneeled there in thought with your face buried in Doe's pussy. You can't believe she would do all of this to you. The feeling of your own cum running down your thigh gives you an idea. Squeezing the muscles in your pussy you catch the cum that comes pouring out in your hand.

You begin eagerly sucking on her clit as you slide your cum soaked fingers into her pussy. Doe is none the wiser as you continue to gather the cum leaking out of you and push it into her pussy. The taste of your own cum leaking out of your girlfriend as you try to impregnate her has your pussy on fire. She cries out in orgasm as your fingers work their way once again into her pussy. Releasing your head she lays down on the bed and you lay next to her.

Now you just had to make sure Alex didn't manage to fill her pussy full of his own cum. With any luck she would be carrying your child as well.

You and Doe decide to take a shower together. It was something you always wanted to do when you were a man, but now you just relaxed under the hot water. Soaping up your body you clean the remaining cum out of your pussy. Now all that was left of the old you was the baby you carried and the cum inside Doe. You spend the next few hours cleaning up the house and making sure everything is presentable for when your master gets home.
