Imagine:
Louis was in a photoshoot. You were admiring how beautiful he is. You see him walking over to you with the biggest smile on his face, he wraps his arms around your waist.
He puts his head on your shoulder and kisses your neck. He turns you to face him. "Hello love" he smirked. You blushed "Hello babe" you reply still blushing. He kissing your lips and then smacks your bum and winks as he walks back to the photoshoot.
