You’re Back Early
Here’s a tip, guys. If your SO’s parents ask you to come at 5 PM, you come at 5 PM. Not 4:49, not 5:01. 5 PM sharp. You don’t want to witness anything that would take years of therapy to erase from your mind, and sadly, that’s what happened to the heroine of this story.
Since the dad wasn’t there yet, the OP and her boyfriend decided to out for a walk. They were chasing each other back to his home, and she won the race. However, she also won a chance to glance at the dad’s family jewels since he was walking around his house nude, not expecting them back until later.
