Imagine your OTP where Person A has decided to volunteer at their local mall as a mall Santa. Person B is volunteering as an elf. 

Person B decides to have some fun with this and lines up to sit on Santa's lap. When their turn comes, Person B sits on Person A's lap, leans close to their ear, and whispers about how naughty they've been this Christmas  

   Bonus: if they go on break and have sex in the fake Christmas house on display
