It was with considerable injury and effort that Superman managed to calm the rampaging dog. Obviously, the Man of Steel could see, the dog needed to be considered in all future plans, and following much intellectual communication with Kan-el, and arrangement was arrived at.
Several months later, Lois gave birth to a number of offspring. The dog's embryo, being a super-embryo, could not be terminated, and so the litter of puppies had to be left to grow alongside Lois' and Superman's super-twins, one male and one female. It was necessary for Lois to quit her job at the Daily Planet and move to the Fortress of Solitude to care for the two babies and four pups. It was far from the ideal situation, for he had to leave Superdog there to guard all of them, and Superman was well aware that while he was absent for days, weeks and months at a time, Lois and the dog would, out of necessity, be sharing pleasure in their remote and lonely clime. Still, he supposed that was better than having Lois, with her newly-awakened and uncontrollable sexuality, on the loose in Metropolis.
Lex Luthor had vanished again and was certainly lurking somewhere, waiting to avenge himself on Superman through Lois. Life was going to be difficult for Superman and Lois as a couple for the immediate future. Still, he supposed things could be worse, and he now had Lois waiting for him at the Fortress of Solitude where, finally, they could have plenty of that-solitude-whenever he could turn manage to get Kan-el to baby-sit and stop sniffing around the woman.
Things could be better, ideally, but then again he had to admit, while gazing into her beautiful, passion-flushed eyes whilst fucking his steely cock into her, that they could be a hell of a lot worse.
