Poses for plus size subjects !?

I have a scheduled photo shoot in about a month for a couple the only problem is that they are very plus sized and want me to capture the best in their relationship and not in their size. they have brought me examples of pics they have done in the past where they claim to have felt covered in props. Can any one help me out on this one. also the lady or girl would like a face shot but she says she has big cheeks she wants somthing maybe shadow casted? I dont know i'm wreckin the brain trying to please this couple
