No, concentrate on the class.

You suppress your impulse to seduce your teacher and spend an hour with him practicing your moves and your posture on the board. It's not exactly "surfing" yet what you are doing, but at least you have learned to keep yourself upright on a surfboard in the shallow water - for a few seconds.

As you walk back to your villa, a salty taste on your lips and salty seawater in your hair, muscles aching and pretty tired, you involunarily think back to the toned muscled torso of your teacher. Your resisted temptation today... but maybe you can give in tomorrow?
