Gender bent Mikasa and Eren. More chapters on the way.

Eren was brushing her long brown hair when someone knocked on the front door. She laid the brush on her bed and went to open the door. When she opened the door she felt two hands grabbing her. She sighed and started to bite him.

"Eren that hurts!" he said in a cry of pain.

"Then don't assault me Mikasa" she said as she pushed Mikasa away.

Mikasa is the adopted brother of Eren when Mikasa's parents died of illness. Mikasa only assaulted Eren when they were alone; sister complex.

"Eren lets go on a date," he said happily, "I'll buy you anything you want."

He started to play with her hair which made Eren mad. She slapped his arm but that wasn't enough to stop Mikasa.

"Eren if you don't go on a date with me, I'll tell Armin about the time you-"

Eren punched Mikasa's stomach, she went to her room and started to get dressed. She fixed her dressed and brushed her hair again and grabbed her purse.

"Fine lets go." she said as she grabbed his hand. Mikasa had a smile on his face.

They walked to the park and sat on an empty bench. Eren felt embarrassed because people were staring at her and Mikasa. Mikasa was enjoying the moment that was happening.

"Eren, when will you become my wife?" he said. He felt a punch on his stomach and felt a sharp pain. He didn't care, if it was Eren then he didn't mind.

"Can you please stop with this?" she said angrily, "It's not normal"

He grabbed her and made her sit on his lap. She wanted to fight back but her face started to turn red from embarrassment. He wrapped his arms on her and started to rub her stomach.

"You know I love you," he said quietly, "You'll become mine eventually."

He then started to put his hands on her chest and then he felt a punch on his face.

"You're a pervert!" she said in an embarrassing tone.

"How come you get embarrassed?" he said. He already knew she wasn't being honest. She would always blush when she didn't know what to do or say.

"Because you always embarrass me" she said in a quiet tone.

Mikasa smiled and grabbed her hand. She blushed again and wanted to die of embarrassment.

"Let's go home" he said "Let's call it a day"

"Fine, I love you," she said as she wanted to cry, "I just don't know what to do."

Mikasa smiled and wiped Eren's tears, he found her expression rather cute.

Mikasa got up and carried Eren in the bridal position. She covered her face with her hands; she really wanted to die.

Mikasa carried Eren in that position, people stared and were whispering how they looked like a happy couple.

When they got home, Mikasa laid Eren on her bed and he got on top of her. He smiled at her and got her lips closer to her rose cheeks. He kissed her softly, Eren started to blush and wanted to him to stop. She pushed him a little, he looked surprised.

"Before we go any further," she said, "Will you be there for me?"

He smiled and kissed her lips. He already promised himself that he would make her happy no matter what.

"Yes," he said as he started to tangle his hands on hers. "I'll always be there for you."

She blushed and then started to look at him with smile.

"Then I'll let you become one with me"

Mikasa blushed a bit and stared to kiss Eren's neck softly. Mikasa wanted to do more than sex with Eren. He wanted to marry her and create a family and make their parents happy.

Mikasa started to take off his shirt. Eren blushed and started to remover her dress. She blushed and started to cover herself. Mikasa saw her beautiful smoothed rose skin and slender legs. He started to kiss her even though she was trying to remove her bra and panties.

Once Eren removed the rest of her clothes, Eren started to take off his pants and underwear. He started to with her body. Eren moaned from the pleasure and was trying her best to hide her panting.

Once Mikasa entered Eren, he saw tears on her face. Eren was hurting but she didn't wanted to Mikasa to stop.

"Eren if it hurts, I'll stop right now."

"Keep going, I'll endure it"

Mikasa keep going slowly trying to have this feeling of pleasure last as long as he can.

4 hours later

Mikasa woke up and saw Eren's face on his chest. He smiled and started to put one of his hands on her cheeks. He looked at all of the hickeys he left on Eren's neck and arms.

I'll protect you, no, I'll give you the happiest life.

Mikasa moved Eren slowly so he could get up. The moment he got up and put on his underwear, he saw their parents standing at the door. He never noticed that they got home early. He was surprised they left their bedroom door open.

"Hi mom, hi dad." he gulped and looked back at Eren who was still sleeping. He was shocked because her clothes were scattered in the room.

"When did you guys came home?"

I'm so dead.

"Can you explain why your sister is sleeping with you?" Grisha said in a loud tone, ignoring Mikasa's question. Carla wasn't mad but she was surprised of what she saw. Her hands were covering her mouth, but she was hiding a smile.

"She's in bed with me because she was tired?" he lied. He felt like if Grisha was going to kick him in the stomach.

"Hun don't be mad, Mikasa and Eren aren't related." she reminded him.

"He's still not getting out of this mess" he said with a glare.

"When Eren wakes up we will talk in the living room" he said.

Eren, maybe I won't protect you long enough.
