This is part 10 of my SAO fanfiction. You can start with Part 1 here.

Kirito and Imouto were walked briskly through the caves, heading for the world tree so that Kirito could climb it and rescue his e-wife from the clutches of the evil fairy king.

Suddenly, Imouto pushed Kirito into a crevice in the rock wall. As she pinned his shoulders to the wall, she simultaneously thrust her hips against Kirito’s sheathed sword.

“Imouto… what is this magic spell you’ve cast on me?” asked Kirito. “I want to eat you so bad right now.”

“Stop it!” Yui scolded, peeking out of Kirito’s pocket. “Daddy, something’s getting closer.”

“Later, Yui. Daddy has some grownup business to take care of.”

“No, Yui’s right.” Imouto said, finishing her magic detection spell. “We’ve got to run. Someone’s coming.”

Kirito and Imouto ran through the caverns. Imouto’s enormous breasts heaved like gelatin, and Kirito studied them closely, admiring ALfheim Onlines excellent graphics and physics engines. Finally they arrived before a town in the middle of a lake. As they approached the gate, their entrance was blocked by a giant earthen wall.

But nothing could stop Kirito. He drew his sword and attacked the wall with all his might. Nothing happened, and he fell to the ground on his rear end.

“Curse those salamanders! I’m going to kill them all!” shouted Kirito, enraged. “I’m a pretty loose guy, but there’s one thing I can never forgive. Cockblocking! This is NOT cool!”

Kirito drew his sword, as Imouto looked on in amazement. It hadn’t looked this big the other day… Imouto drew her own sword, pitiful in comparison, and prepared to do swordplay at Kirito’s side.

“I want you to stay in the back and heal me,” said Kirito. “Squirt your magic healing spells into me from the rear.”

“That way, I can fight harder with a harder sword.”

Kirito attacked, but his penetration attempts were blocked by the enemy’s shields. Cockblocked again. Kirito was enraged. He was taking tons of  damage from the enemies, but Imouto’s life-giving juices coming into his rear kept his sword upright before him.

“No, Kirito! We can’t win this!” shouted Imouto, screaming in a combination of pain and ecstacy. “They have protection! Let’s give up!”

“Get behind me, Satan!” shouted Kirito, taking time to look back amidst the roaring flames. “Wearing protection is an affront against God. I cannot let this stand. While I’m alive, I won’t let any party members die, neither the born nor the unborn.”

“Go, daddy! Use the magic spell!” shouted Yui.

Kirito had saved up all the mana he had received in the rear from Imouto. He chanted the words of the magic spell, and transformed into a giant.

“I thought your sword was huge before, Kirito… but now… you’re a monster! A beast!”

Kirito destroyed the enemies in short order, swallowing some of them whole.

“Kirito, how did your body become so enormous and stiff? It’s like your sword became alive, and turned into a monster…!”

“That happens to me sometimes… but only when there’s something I like. When they use protection to block my sword, I just want to stick my sword in them all the more. I got to feel like a monster! It was lots of fun!”

“Kirito… don’t you like me?”

“I like you.”

“Then why won’t you eat me too, like you did with the Salamanders?”

“Swordplay is no fun when it’s consensual. But if you insist…”

Kirito ate Imouto.

Later, feeling refreshed, Imouto prepared to log out.

“Take care of my body, Yui-chan. Make sure your dad doesn’t do anything to it.”

“Daddy would never do anything like that!”

“Yui’s right,” interjected Kirito. “I thought I already told you. I’m not interested if it’s consensual. And you’re clearly consenting.”

Kirito sped off at the speed of light, dragging an unwilling Imouto behind him into the future. He needed to find Asuna. The stakes were too high. He had to get in a position to observe the cage on her wedding night. As a serious student of swordplay and Asuna’s lover, he had to witness this sparring match from a ringside seat.
