Fuck your college-age sister again

You're about put your cock back in her so as to cum inside her once more when she pushes you down onto your back.

She straddles your crotch, aims your cock at her opening, and shoves down hard. You hear her moan as your cum shoots out inside of her, but she then quickly begins to bounce on top of you at her own pace this time At first you feel uncomfortable with her weight on top of you, but she is too good for you to tell her to stop. You cum. She cums. You cum again. So does she. And again. And again.

After you cum in her for the ninth time, both of you are spent. But your spiritual senses tell you what you want to know: she is pregnant with your child now.
