Your dad is out of town for a couple of days, and it is a perfect time to get to know your new step-mom. However, she finds out that after all these years, your dad still hasn't told you about the birds and the bees. As she is trying to get pregnant, you were curious as to how it happens. Being 18 years old, she is shocked that you have no idea how it works. She tries explaining it, but you are more of a visual, physical learner. She decides to teach you, letting you lose your virginity to her. However, you cannot cum in her, as she is ovulating. While you try not to, it is difficult for you to control yourself. You end up filling up her pussy with your sperm, impregnating your step-mom's fertile womb... Let's hope your dad doesn't find out!
