Push it in and fill her womb.

From Create Your Own Story

The thought of impregnating your little sister breaks you.

You grab Kayla in an inescapable embrace and slam it deep within her walls, kissing her womb as it stimulates every nerve on your rigid dick.

"Jason!" She weakly cries out your name and gasps as you release your load inside of her.

You spend nearly a minute filling your sister with your seed, and just you think you are done you feel your cock perk up and fire a final three jets into her snatch.

For a while you linger inside of her, kissing her tear streaked face and relishing in your incestuous act. She continues to lay under you almost limp now, not reciprocating in any way.

It was the best sex you have ever had, the best she has ever had, family time well spent you think. It fills your dreams with fever for the rest of your days. But alas, it is only your dreams and all good things...

Upon hearing of her pregnancy you are elated, but you are the only one.

Kayla, your family, and your girlfriend pretty much disown you, and you are no longer popular in any social circles. Was it worth it?
