Don't impregnate his wife

Your best friend, Jake, begs his wife Amy to get impregnated by you, b/c he wants to be a father & his sperm count is too low. Amy agrees to Jake to make him happy, but now that she is next to you in bed, she realizes this is a BIG mistake. She feels she isn't ready to be a mother. She is terrified that fucking another man and carrying his child would emotionally devastate Jake some years later. Sure, Jake is desperate to be a father, so desperate that he is willing to be cucked by you. But what if Jake later regrets this decision? What if being impregnated by you destroys what little self-esteem Jake has? Amy looks at your giant bulge with desire, yet she tearfully rejects you, b/c she knows fucking you will be a huge mistake that will derail her life. Will you help make her and Jake proud parents of a wonderful child? By cucking your best friend?
