muffin smuggling

When you sneak a woman onto an airplane in your carry-on or checked luggage for the express purpose of engaging in consensual in-flight sex through a hole previously created in the side of said luggage.

Flight attendant: “Excuse me, sir, but please remove your penis from that luggage. I’m worried you’ll get sperm on your travel items.”
Frequent flyer with his penis in a piece of luggage: “Thank you for your concern, but there are no travel items in here, only my wife. We’re muffin smuggling as a means of keeping our marriage strong.”
Flight attendant: “I see. It’s important to do things as a couple. Can I get you a ginger ale?”
Frequent flyer: “Yes. Can I have also have an extra pack of cookies?”
Flight attendant: “No.”
Wife, from within the luggage: “I love when we muffin smuggle.”
Frequent flyer, his penis still in a piece of luggage: “Me too, dear.”
Pilot: “We’ll be landing in 15 minutes.”
Flight attendant: “Sir, I’m going to need you to exit the overhead compartment and return to your seat.”
