I would ask them if they were looking for any shots in particular, or standard posing. If they give you some ideas work with it, if not, just do standard poses, boy-behind-girl, facing each other, maybe a group shot, individual poses.
Treat it as if it were any other type of shot you do with 1, 2 or more people in it.
Get the standard stuff first, then if you have time, try fun stuff.
