Jacob and Jessica were deeply in love and completely on track for a beautiful marriage. There was only one glaring problem: Jessica’s stunning 20-year-old sister. She had a habit of wearing impossibly tight miniskirts and making suspiciously deliberate, low-cut wardrobe malfunctions whenever Jessica left the room. Jacob tried his best to ignore it.

One afternoon, the younger sister called Jacob, asking him to swing by the house to help proofread the wedding invitations. When he arrived, the house was dead silent. She was entirely alone.

Sauntering over to him, she whispered that she had developed an overwhelming, forbidden desire for him. “Just once,” she purred. “I want to have you just once before you commit your entire life to my sister.”

Without waiting for an answer, she turned and headed up the stairs. At the top landing, she provocatively slipped off her panties, tossed them down the steps right at his feet, and vanished into her bedroom.

Jacob stood frozen in absolute shock for a few seconds. Then, turning on his heel, he bolted out the front door and marched straight down the driveway toward his sedan.

Waiting right next to his vehicle was his future father-in-law, wiping tears of pure joy from his eyes. The older man stepped forward, wrapping Jacob in a massive, emotional bear hug.

We are so incredibly proud of you, son!” the father cried. “You passed our little family test with flying colors. We couldn’t ask for a more honorable man for our daughter. Welcome to the family!”

The moral of the story: Always, always keep your condoms in the glove compartment of your car.
