Concentrate
"Fiyero, you do realize, don't you, that I'm trying to concentrate?" Elphaba whispered fiercely, praying that no-one would notice what was going on.
Fiyero's answer was a mere grin as he squeezed Elphaba's knee.
Elphaba shook her head. "You're infuriating, do you know that?"
"Uh-huh."
"Oooh, I am so going to wipe that smirk off your face as soon as we get out of here."
"Can't wait," was Fiyero's smug reply.
"Class dismissed."
Elphaba was, for once, the first through the door, Fiyero hot on her heels. The green-skinned girl turned a corner sharply. As soon as Fiyero turned, Elphaba grabbed a handful of his shirt and pulled him to her, kissing him deeply.
"Is this is price I have to pay for not helping your concentration during class?" Fiyero whispered cheekily.
Elphaba merely kissed him again.
