I was about to abandon this but since people have asked for a second chapter I could'nt resist.

This fic is pretty much where I plan to practice writing smut.

"Holy Shit" Levi said.

Pinned down before them was a twelve meter Titan with black hair and huge muscles.

"Don't worry Levi" Hanji reassured the Corporal. "That's Mikasa"

"What?" Levi qustioned.

"I knew this might happen so I made sure that we placed them in an isolated cabin." Hanji told him.

"Then why'd you proceed with the transfusion?" Levi said, angrily.

"It was a life or death situation. Eren begged me to do something" Hanji explained "And I wanted a new titan so oops."

Their conversation was interrupted when Mikasa gave off a sound. Not a scream nor a growl but something akin to a whimper. Levi and Hanji placed their hands on their blades as Eren slowly let go of Mikasa.

"She seems to have some degree of control." Hanji declared "Must be because she isn't a true Titan Shifter."

"Should I cut her out?" Levi inquired

"No" Hanji's face turned serious. "Let's observe first."

"We can't just leave them like that."

"She's not a true titan shifter so her transformation won't last long."

True to what Hanji said, Mikasa's transformation only lasted for thirty minutes.

"Hey" Eren was showing genuine concern. "How're you doing?"

"F-fine" Mikasa managed to choke out.

"Mikasa".

"Yes Eren?"

"Sorry"

"Wasn't your fault. I shouldn't have been careless while riding that wagon."

Eren only stared at her with compassion. The only reason as to why they couldn't totally retake Wall Maria was lying right in front of him. He couldn't use his Coordinate ability after he saw Mikasa's wounded form.

The wind was blowing against his hair. Close to his wagon were other wagons and the horses of the Scouting Legion. They were using a new formation. This one only relied on a hundred soldiers. All of the soldiers were supposed to be escorting him, Eren Yeager the coordinate.

After Historia was put on the throne, the Scouting Legion had much more freedom. Today, they would be using a hundred Titans to clear the path to Shiganshina district. After that, they would seal the hole in Wall Maria.

Burst!

Eren's thoughts were interrupted by the malfunctioning of the wagon next to his. The suspension system had broken, causing the wagon to spin out of control.

"MIKASA!"

To his horror, he saw the girl he loved get hit the worst in a horrible accident. Seeing her blood, he lost control of his ability.

They lost twenty-six men in order to get back to the walls.

"I think she was a twelve meter class." Hanji was about to finish reporting her findings to Erwin. "She was much more muscular than Eren though. From the latest blood samples we can say that most of her cells are starting to convert into Titan Shifter cells."

"I see. Anything else?"

"Yes. From what we've heard Eren went berserk on his third time transforming. It could've been the stress but I recommend we assume that during the third transformation, Titan Shifters turn unpredictable"

"What do you recommend?"

"I plan to have Mikasa transform two more times so that we can get past the phase where she might go berserk."

"This may delay our plans Hanji."

"She may be able to Crystallize. We could use that for resealing wall Maria."

Placing a hand on his chin, Erwin began to think.

"You have two weeks. I'll be in Sina for that period of time since I have to oversee the reconstruction of the system."

Mikasa and Eren were sleeping in a tent that was a hundred meters from the HQ.

"Eren"

"Yeah?"

"Tomorrow when I transform" Mikasa's face turned serious. "If I go berserk I want you to-"

"Ssshh.." Eren's lips made contact with Mikasa's, effectively shutting her up.

When their kiss had subsided Mikasa said something that signaled the beginning of the highlight of Eren's night.

"You know, I'm not that tired."

Moments later, Eren's member was positioned outside Mikasa's entrance. Seeing him look at her for permission, Mikasa nodded.

Eren made sure to move slowly. He had no intention of causing her pain. Overtime, he gradually picked up the pace.

"Eren" The way Mikasa uttered his name was almost incoherent as it was mixed with a moan.

Submitting to the pleasure of the moment, Eren and Mikasa's world became small. They were alone.

Most of all, they were happy.

The same couldn't be said for Jean who was tasked with guarding them.

Mikasa was positioned in the middle of the courtyard, her hand mere inches from her mouth. Thirty meters away, Eren was positioned with his hand close to his mouth as well.

"Whenever you're ready Mikasa" Hanji told the younger female.

After a huge burst of lightning and smoke, a fourteen meter class Titan was in front of them.

"Alright." Hanji was smiling. "Raise your right foot."

Mikasa complied.

"For the next test you'll build a cabin using the logs we've provided."

Within a few minutes, Mikasa had built a small cabin.

"Alright! Now try to harden!"

After several attempts, everyone came to the conclusion that Mikasa was'nt able to harden.

For the last transformation, Eren was ordered to be in Titan form before Mikasa transformed.

"Mikasa"

The raven haired girl looked at Hanji before nodding.

"Now."

Another burst of light occurred and a Titan now stood before them.

"Hrrr..." Mikasa looked like she was looking for something. She found what she was looking for when her eyes caught sight of Eren.

Eren was already in a fighting stance when he saw that Mikasa was running towards him.

Mikasa lunged forward, aiming for Eren and embraced him.

Hanji never thought she would see the day when a Titan would give another one a hug.
