Your step-sister calls you over to her house and when you get there it is clear that she is not in the greatest of moods. She is sad, but she doesn't want to talk about it. All she wants is to have her step-brother there to cheer her up.

But it's bothering you seeing her so upset, so you keep asking her what is the matter until you get the truth out of her.

She's upset because she wants to be pregnant. She wants it more than anything, so bad that she even considered going to a sperm bank. She knows how silly it all is. Then... she starts to say something and stops herself....

She's upset because she wants to be pregnant. She wants it more than anything, so bad that she even considered going to a sperm bank. She knows how silly it all is. Then... she starts to say something and stops herself. You prod her some more, and finally she tells you the other thing she's been keeping from you.

You're the only man she would want to get her pregnant. She knows just how wrong it is, but she can't help but feel that way. You're perfect in every single way and you're the only one she would want to do this with.

Taking her by surprise, you tell her that you want to be the one to get her pregnant. You've also had feelings for her, your step-sister.

Unable to contain her excitement, and wanting to get pregnant right away, she strips off all her clothes and before you know it, your step-sister is on top of you. She rides your cock, going up and down, before slowing down. She wants you to work up as much cum as possible, so when you do cum inside of her, it is the absolute biggest load.

Then, she has you lay her back on the bed, and as she is laying down, you go back inside of your step-sister. You keep on making love to her this way, as she tells you just how much she wants your cum deep inside of her, exploding against her womb, until you do just that. The two of you cum together, and you both just know, you just impregnated your step-sister.
