"NSA"

 Amtrak 'Sunset Limited'
 Phoenix/Maricopa to New Orleans
 Clickity-clack, clickity-clack
 
 Sitting in the dining car
 Random assigned seating  
 Opposite reservation card, 'Mia'

 Porter leads her down the aisle
 I stand, holding her chair
 We chat, question, eat, drink, flirt

 Connection made, NSA
 Quick walk to a sleeping berth  
 Hand at her lower back

 Sit, kiss, fondle, foreplay
 Doggie, pull hair, pound
 Clickity-clack, clickity-clack

 Satisfy, rinse, repeat

 *Point of reference: "NSA" is No Strings Attached*
