I wouldn't want to be creative, instead I'd rather be planned. Observe her daily routine and looking for periods of isolation to minimize witnesses. You'd also want to check up on her network, friends, co-workers, and so on. If you're going to rape a woman, the less contacts she has - the better, leads to less chance of unannounced visits.
Of course, the actual act of rape itself needs to be thought out. It's not very smart to try and have her blow you, because she might bite down. Positions which insure that she has less chance of fighting back are ideal. It takes too long to actually tie her up for it, so you simply have to choose your positions carefully.
You can't forget that the less chance of being ID'd, the better. It's a good thought to choose a target that isn't in your general area.
