Go Home, take a pregnancy test.

After you get to shore, you say your goodbyes to Rick, get a taxi to the airport, and go home.

The next day you and Jen go to a pharmacy together and buy a pregnancy test. The clerk wishes you good luck, unsure of whether he meant good luck with the baby or not. He congratulated you on impregnating such a hot babe, Jen felt embarrassed and left.

Long story short, the results were as expected: Positive.

You tell both your parents the news. Your parents took it much more positively than Jen's parents did. But since you were taking responsibility for this, they finally agreed to accept you into their family.

Nine months later, a beautiful baby boy was born. Jen and the baby are healthy as ever, and recovering quickly. A lot of people are complimenting you, and they tell you how much the boy looks like his father.

Of course he does, Jen didn't have sex with anyone but me, ever.

-You think to yourself, proud that you managed to impregnate Jen the first time you ever had sex. You have strong swimmers indeed.

The End.
