Setting: Right after an Expedition. A few months after the fall of the evil regime.

I decided to give smut a try. The smut is rushed so I'm sorry for any blunders. I do not own Shingeki no Kyojin.

"Hang on Mikasa!"Eren screamed. The sight of her bleeding made his insides shiver. "Eren" Her voice was weak. "I'm sorry... I... Probably won't la-" Eren pressed his lips against hers. "I love you. Please don't die." Her will to live, previously a dying candle, became a hot sun. "Don't worry I won't... I love you too." Mikasa smiled before passing out.

She had been injured, not by a titan, but a mishap with a wagon.

Mikasa woke up to find that she was sharing a bed with Eren. A rubber tube connected Eren's arm to something. A second rubber tube was on the other side of the object. The other tube was connected to her arm.

"Morning sleepyhead." Eren said.

"Eren, what's with this rubber tube?"

"Miss Hanji is using one of her inventions to give you some of my blood. Don't worry, I have an unlimited supply."

"Wha-" Mikasa's eyes widened.

Eren cut her off. "You have me flowing through you, Mikasa"

She turned red before passing out, again.

"Mikasa, wake up." Miss Hanji tapped her shoulder.

"Good afternoon, Miss Hanji"

"Please call me Zoe."

"O-okay Zoe."

"Your boyfriend seems to have fallen asleep." Hanji looked at Eren, who was right beside Mikasa.

"He's not my-"

"Don't worry, so far the only people who've caught on are Me, Levi, Erwin and Armin. You're good at hiding your relationship."

"Oh." Mikasa turned bright red.

"Time to remove the tubes. You're a very lucky girl. Who'd have known Eren's blood was compatible with yours?"

Mikasa looked at Eren. "I agree, I am lucky, very lucky."

Hanji smiled, knowing what Mikasa had meant.

Mikasa woke up in the middle of the night, her hands were wrapped around Eren's waist. She discovered that Eren was awake, looking at the ceiling.

"I love you." Eren whispered.

"I love you too." Mikasa replied.

Eren pulled her in for a kiss. She kissed him back. She soon found herself on top of Eren, desperately kissing him. Eren was doing the same. They broke off to breathe then went at it again. Eren's hands made their way under her shirt. First, his hands indulged upon her abdominal muscles, causing Mikasa to give off a moan.

Then, they made their way to her breasts, cupping and squeezing them. Mikasa, not wanting to be bested, unzipped Eren's pants before indulging upon his member with her hand. The action caused Eren to moan. Eren's right hand made it's way to her pants, unzipping the said article of clothing, then indulging upon her moist entrance.

"H-how many?" The words suddenly escaped from Mikasa's mouth.

"What? What do you mean?" Eren was caught off guard.

"How m-many other women have y-you done this w-with?"

"None. You're my first." Eren was slightly embarrassed.

"Y-you're mine t-too." Mikasa spoke before he could ask her the same question.

Eren's fingers played with her clit, vigorously. Entering her was a privilege he had reserved for his member. Eren's actions caused Mikasa to moan. Mikasa lost the ability to focus on Eren's member, she had lost herself to the flood of pleasure. Eren soon found himself unable hold back.

Their clothes now littered the floor of the bedroom. Mikasa was in a position that didn't affect her injuries. while Eren was in a favorable position, ready to thrust his hard member into her.

"Mikasa, do I have your permission?" He asked.

"Y-yes. Please be gentle." She requested.

Mikasa let out a moan as Eren's member made it's way into her, slowly and gently. The last thing Eren wanted was to hurt her. Blood started to leak out from between her legs. Eren gradually picked up the pace. Mikasa did her best to prevent the moans from escaping but each time she tried, she was met with failure. Eren made no effort to hide the fact that he was saying her name repeatedly.

Mikasa suddenly felt a jolt of sensation pass through her. Her walls tightened on Eren's member as she reached the peak of pleasure. Eren wasn't that far as well. As soon as he heard Mikasa's cry of pleasure, he exploded inside of her.

"Eren!"

"Mikasa!"

Hanji visited them in the morning. "Here Mikasa take one of these." Hanji handed her a jar full of pills. "We wouldn't want any unexpected gifts."

Eren and Mikasa both turned red.

"Anyway..." Hanji decided it was time to change the subject. "The tests all came back with good results. Mikasa's body isn't rejecting the blood. Eren has probably replaced all the blood by now. Eren's blood didn't increase temperature again after the machine cooled it before proceeding to give Mikasa the blood." After giving them the results of the tests Hanji's expression turned serious. "Be more careful next time."

Mikasa bit her lip, strong enough to draw a small amount of blood.

I won't fail Eren again. I will protect him.

A sudden flash of light and a clap of thunder occurred.

Everything was a blur at first. Mikasa could hear Hanji's excited screams along with another clap of thunder. Her vision started to come back.

"Jaeger keep her pinned down! Braus get my 3DMG!" Levi's voice.

"Is that Mikasa!?" Armin's voice.

What's wrong? Why is everyone in a fuss?

Everything became clearer. She had regained her grip on reality, she saw that Eren's hands held both her shoulders. He had her under a hold. Eren was keeping her pinned down.

In his titan form.
