Orochimaru had something to ask his former Sensei. As it wasn't very important, it could wait until later...
In one universe, it did wait until later. In this one however...
He had just opened the door to his sensei's office a crack. From what he could hear, his sensei's "important" meeting which the secretary hadn't wanted him interrupting was a discussion about who would be Yondaime.
"I'm really sorry, but the law states that you can't name a foreign born shinobi Hokage, even if they are related to both the First and Second Hokages." Sarutobi-sensei's former teammate Homura was saying.
"I have an idea." Koharu-san said. "Why don't we name the man Kushina marries to the position of Hokage?"
"Why should we do that?" Sarutobi-sensei asked.
"We all know that Kushina is going to be the one wearing the pants in any marriage she gets into..." Koharu said.
Orochimaru closed the door and walked away thinking. Jiraiya's student Minato was currently dating the annoying redhead. If the boy married her...
He would just have to woo her, win her, and poison her the day he was named Hokage.
Twelve years later:
"Orochimaru! Bring me my breakfast!"
"Yes dear."
Orochimaru made his way out of his and his wife's bedroom glad for the millionth time that he'd abandoned all research into that immortality jutsu. Chances were that Kushina would stay alive forever just to spite him. She'd never even noticed when he poisoned her food, and had healed up quite nicely after he'd slit her throat during a particularly nasty argument. In fact, she'd done that several times.
That little hellspawn that Namikaze Minato had managed to sire before he'd broken him and Kushina up stood in the doorway of his bedroom snickering at him, as did one of his younger half sisters who had been born with that devil-woman's red hair.
For the millionth time, Orochimaru regretted the fact that he'd been greedy and done what it took to be named Hokage. For the nine-hundred thousandth time, he regretted the fact that he'd protected Kushina as well as he had, since Uchiha Madara had gone after the decoys he'd sent out of the village. If he hadn't, Kushina would have been out of his hair long ago. Sure, he'd have had a giant fox to deal with, but Kushina would be gone. Madara never got a second chance to attack. He didn't know what Kushina had done to the man who had "threatened her baby", and frankly he didn't want to know, especially considering the fact that the poor man whose skills far outstripped those of his former sensei had pissed himself and ran when he'd accidentally run into her when he'd shown up again eight years later to destroy the village.
There was only one aspect to his marriage to Kushina that he enjoyed. Unfortunately, this had played into Kushina's irrational desire to have a dozen children, a goal that they had already met, and would be passing in a few short months.
Orochimaru sighed in relief when he reached the kitchen. Kushina's personal chef Teuchi already had a half-dozen bowls of salt ramen prepared. He wouldn't be running from a red eyed pregnant demon witch this morning.
After delivering Kushina's breakfast, he quickly grabbed his hat and robe and dove out the window, racing for the office before he got roped into helping deal with the morning chaos that was nominally his household.
