How about Lana being abducted by an extremely ugly, slimey, alien creature hell-bent on conducting impregnation experiments on Lana with his multiple, grotesquely over-sized male reproductive organs.  I can imagine the creature probing your every opening simultaneously and over and over as he injects his alien semen into your host body until he achieves success.  The "seed" for this idea actually cums from a couple videos I saw on the ZFX Productions site.  Hey............another porn video opportunity  for you, sweetie.
