Ideas for my photo project PLEASE ?

My project is to make 5 campaign posters about something that has a negative connotation ociated with it. My idea is and alcohol. I am using the studio and have 5 friends (females) who are willing to help out by being models. I shot one so far, and she wore just her underwear and we made a fake bruise on her chest and had an alcohol bottle in the picture. My problem is that I have 4 moer models and I want these other pics to be more original. Any ideas?? thanks
