Okay so what if, and stop me if you've heard this before... but what if Superman, with his superhearing heard Lois moaning, and went to her, and then with his x-ray vision he looks through the roof of the house and he sees Bruce Wayne making love to Lois?
And then he watches, he hears, he can smell them, he can taste the mingling of their juices, he focuses on a bead of sweat that runs down Bruce Wayne's back and into the crack of his ass, and then we zoom into the crack, we zoom in to the hole, we zoom in until we emerge from his penis with the sperm as he ejaculates us into Lois Lane's vagina, we ride the sperm, we follow them like salmon upriver, all in one take, and finally we see it, we see the egg, we follow the one, the chosen one, the one sperm who will make it and survive, the millions perish, with Superman's hearing we hear their death throes as Bruce and Lois' voices join into a chorus of le petit mort and finally in a crescendo the chosen sperm enters the egg and they become one, and we depart, we pull out from Lois like Bruce does, and he rolls off and lies on his back next to her, and they look up and we follow their gaze through the roof, still all in one take, until we return to Superman's eyes, then the camera rotates around to show his face, he is making the Come and See face, the tears roll, the sex scene is replayed in the reflections of his tears, and then a single tear falls for his face, we follow it, we see the sex in the drop until it splatters onto the roof where it breaks, and then we dive into the splattered drop, and we are in the ocean, and we go on to the next scene in Atlantis.
Kind of like that.
