Unless you’re fornicating on a campus rooftop, you should always close the blinds when you sneak off upstairs to do some bid’ness.
From the description: “During a party at our place, my housemate decides its a great idea to bring a girl up to the roof to start makin moves. After they move things inside, he forgets to close the blinds…”
Nothing too crazy. But gotta love when the couple ducks after being spotted.
