Just popped into my head the other day, and thought it might be an interesting scenario here:
Two models are stuck in a room, already desperate and in need. However, this is absolutely nowhere to go, not even anything to go in ... except ... They are each presented a large cup of water and told they can go in it if they can finish it. Either we see a beautiful woman losing it on the floor/her clothes, or we see a beautiful woman filling a cup she just emptied. Win-win! Sorry if this has been done before, I haven't had time to go look.
Of course this could be done with one model, but I enjoyed the idea of two for fantasy.
