Your best friend just left her fiancé and comes over to tell you the news. There's something else she wants to get off her chest, she's been in love with you for years and wants you to get her pregnant. Why not get started right away? She strips down and starts riding your cock in different positions while talking about how bad she wants you to impregnate her. You both cum together and give her a big cream pie. That's what best friends are for.
